If the facts alleged in yesterday's indictment are true, the Trump Organization and its longtime chief financial officer, Allen Weisselberg, have engaged in blatant tax evasion for more than a decade. Early reports characterized the crime in question as involving "fringe benefits." This gives entirely the wrong impression. The Trump Organization and Weisselberg aren't being charged with tripping
Kaboom! Right now, the northwest United States and the western chunk of Canada are in the throes of a relentless, infrastructure-melting heatwave that's already killed hundreds of people . Wildfires in the same areas are making matters worse, and severe drought has essentially turned much of the western US into a tinderbox waiting for a spark, It certainly seems like a good time for everyone to t
From the Frying Pan Ninety percent of Lytton, British Columbia, a small village of approximately 250, burned to the ground after recording Canada's highest ever temperature ever of 49.6 degrees Celsius (121 Fahrenheit) — in the same week. "There won't be very much left of Lytton," Jan Polderman, mayor of the village, told the BBC . "There was fire everywhere." Much of the west coast is experienci
I n another lifetime, Representative Anthony Gonzalez was the Ohio Republican Party's dream candidate. Many of his future suburban-Cleveland constituents cheered for him at Byers Field when he was a high-school-football standout at St. Ignatius, and later again at the Shoe in Columbus during his star turn as an Ohio State University wide receiver. The son of a Cuban immigrant, he was a first-roun
A paper based on joint research by Prof. Yuan Changzheng from Institute of High Energy Physics of the Chinese Academy of Sciences, and Prof. Marek Karliner from Tel Aviv University of Israel, was published in Physical Review Letters. It points out a new abundant source of antineutrons and hyperons. These rare subatomic particles are essential for studying forces governing the behavior of matter at
After several weeks of bad weather and strong winds, the latest pair of high-altitude drop tests of the ExoMars parachutes took place in Kiruna, Sweden. The 15 m-wide first stage main parachute performed flawlessly at supersonic speeds, while the 35 m-wide second stage parachute experienced one minor damage, but decelerated the mock-up of the landing platform as expected.
In the beginning, the small group of Americans who aspired to become astronauts had to pass an isolation test. Spaceflight wasn't going to be easy, and the country wanted people with tough minds. For his test, John Glenn sat at a desk in a dark, soundproofed room. He found some paper in the darkness, pulled a pencil out of his pocket, and spent the test writing some poems in silence. He walked ou

American sprinter Sha'Carri Richardson was set to break records at the Tokyo Olympics this month, but a positive marijuana test could force her to miss the event entirely. Richardson won the women's 100-meter race at the US track and field Olympic trials in Oregon in June, putting her at the forefront of US hopefuls. At a blistering 10.86 seconds, that made her a favorite to go for gold in Tokyo,
Repeat surgeries for endometriosis could be exacerbating pain symptoms, experts say It has long been believed that the best way to treat endometriosis, a chronic inflammatory condition that affects one in 10 women globally, is by performing laparoscopic surgery to remove damaged tissue from the body. But experts now say the surgery may not be as effective as once thought in relieving symptoms, an
Billionaire Brawl Take that, Jeff Bezos! Virgin Galactic founder Richard Branson just one-upped the Amazon and Blue Origin founder in the race for the first billionaire tech founder to leave the Earth. Early last month, Bezos announced that he and his brother would fulfill a lifelong dream by dipping their toes into space on one of his company's rockets on July 20. But Branson couldn't let that h

A fter most of a condominium tower in Surfside, Florida, collapsed last week, the second-guessing began almost immediately. Some residents accused the building's condominium association of acting too slowly to address known structural flaws identified in a 2018 engineering report. Recent news stories have emphasized dissension among the owners. As someone who studies condos—their history, archite
Scientists find micro-organisms from the bovine stomach have ability to degrade polyesters in lab setting Bacteria found in one of the compartments of a cow's stomach can break down plastic, research suggests. Since the 1950s, more than 8bn tonnes of plastic have been produced – equivalent in weight to 1 billion elephants – driven predominantly by packaging, single-use containers, wrapping and bo
Scientists say agreement must cover extraction of raw materials and pollution that blights seas and land A binding global treaty is needed to phase out the production of "virgin" or new plastic by 2040, scientists have said. The solution to the blight of plastic pollution in the oceans and on land would be a worldwide agreement on limits and controls, they say in a special report in the journal S

What's in a Name? Children can be cruel. So in an era with seemingly ubiquitous "smart" tech, it shouldn't be too surprising to hear that children are particularly horrible to kids named "Alexa," thanks to the virtual assistant of the same name . The teasing has become a real problem, especially among children who never knew a world without smart speakers and the like. At least one family, the BB
Baby Doge After months of hyping up alternative cryptocurrency Dogecoin on Twitter, Tesla CEO Elon Musk appears to have adopted his next shiba — figuratively speaking, that is. "Baby Doge, doo, doo, doo, doo, doo," the billionaire wrote in a Thursday tweet, a song presumably about the synonymous alternative cryptocurrency, seemingly arranged to the tune of the hit children's song "Baby Shark."

Disparity is a 'thorny problem' as citations are a key metric in job evaluations and promotions While more women are entering the field of academic medicine, they are less likely to be recognised as experts, receive prestigious awards, hold leadership roles or author original research in major journals. Research has now shown that papers written by women as primary and senior authors have roughly
A team of researchers has determined that a man died of wounds from a shark attack 3000 years ago. The 790 wounds on his remains, including a missing leg and hand, are consistent with this hypothesis. Given how rare shark attacks are, this find is truly remarkable. Trying to learn about the distant past is often difficult. The remains of ancient humans can sometimes seem baffling, and trying to d
The abrupt abandonment of handshakes and hugs. An expansion of personal space in public to six feet.

A pair of researchers from the University of Newcastle and the German Center for Integrative Biodiversity Research has documented a water scavenger beetle walking on the undersurface of a body of water. In their paper published in the journal Ethology, John Gould and Jose Valdez describe the beetle and suggest some theories to explain the unique behavior.
A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not t
This article was originally published on our sister site, Freethink. Researchers at the University of Pennsylvania have reversed a genetic form of blindness in a patient using just one course of antisense oligonucleotide therapy, Clinical OMICS reports. The therapy, which takes aim at mutant RNA, was injected into the patient's eyes a year ago, in a trial treating Leber congenital amaurosis (LCA)
A year after University at Buffalo scientists demonstrated that it was possible to produce millions of mature human cells in a mouse embryo, they have published a detailed description of the method so that other laboratories can do it, too.
A team of researchers affiliated with multiple institutions in Japan, and one in Norway has found evidence that suggests domesticated pig genes in pig-boar hybrids living in the Fukushima exclusion zone are diminishing.

NASA's newest six-wheeled robot on Mars, the Perseverance rover, is beginning an epic journey across a crater floor seeking signs of ancient life. That means the rover team is deeply engaged with planning navigation routes, drafting instructions to be beamed up, even donning special 3D glasses to help map their course.
In August 2013, food critics in London sampled the world's first lab-grown hamburger . Opinions on taste and texture varied, but most agreed it wasn't all that different than meat from an animal. At the time, the cultured meat's taste and texture didn't seem like too big of a concern, because the cost of making the burger—a cool $330,000—meant this technology was years away from reaching the aver
There are plenty of negatives associated with smart technology—tech neck, texting and driving, blue light rays—but there is also a positive: the digital age is not making us stupid, says University of Cincinnati social/behavioral expert Anthony Chemero.

David Attenborough, asked a few years ago by journalist Joanna Nikodemska about the animal he finds most interesting, answered after some consideration that he's most fascinated by a three-year-old human child, whose potential for development and adaptation are simply limitless. The same journalist and I have been verifying this opinion for over eight years now – indeed, observing the development
Stephen Menendian, a researcher at UC Berkeley, has long worried that Americans don't understand how pervasive housing segregation is. They couldn't, he reasoned: Much of the research on it has failed to fully capture its scope. The dominant tool that scholars have used to assess the problem, known as the dissimilarity index, measures how racially mixed a given area is. According to the dissimila
In dozens of novels written over a decades-long career, the romance writer Jackie Collins sharply observed the role of sex and power in Hollywood . She wrote incisively about abuse in the industry and empowered female characters who found liberation in a male-dominated world. She was brilliant and prescient—and overlooked in literary circles by those who wrote off her work as trashy airport smut.
The fast-moving decline and extinction of many species of detritivores—organisms that break down and remove dead plant and animal matter—may have dire consequences, an international team of scientists suggests in a new study.
Synthetic biology offers a way to engineer cells to perform novel functions, such as glowing with fluorescent light when they detect a certain chemical. Usually, this is done by altering cells so they express genes that can be triggered by a certain input.
Life is full of complicated and difficult moments, but we can become better at dealing with them. This practical wisdom is a cornerstone of Aristotle's ethics. When we practice this skill, we become more adept at seeing situations and people differently — not unlike an artist viewing a painting. The elderly and experienced of this world have such wisdom in spades. But those of us in the West rare
After having been postponed for a year because of the coronavirus pandemic, the quadrennial European soccer championship began in June, hosted by 11 different cities across the continent.

The analysis estimates pollution reductions between 1999 and 2019 contributed to about 20 percent of the increase in corn and soybean yield gains during that period – an amount worth about $5 billion per year.
Nitrogen is essential for all life on Earth. In the global oceans however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found in marine waters can convert nitrogen gas (N2) to ammonia (known as N2 fixation), and thereby supply the marine food web with nitrogen.
Both Sides Even reputable news organizations can utterly screw up, which is exactly what the BBC did when it published a widely-mocked study guide for children that listed 15 "positive impacts" that global climate change could have on the world and the UK. The guide was promptly scrubbed of its "climate change is good, actually" content after widespread criticism, Earther reports . But the fact r
Astronomers have developed a new artificial intelligence (AI) technique to remove noise in astronomical data due to random variations in galaxy shapes. After extensive training and testing on large mock data created by supercomputer simulations, they then applied this new tool to actual data from Japan's Subaru Telescope and found that the mass distribution derived from using this method is consis
Hot vents in the deep sea are home to microbes that feed on ethane. Now researchers have succeeded in finding an important component in the microbial conversion of the gas. They were able to decode the structure of the enzyme responsible for the ethane fixation.
Plant diseases are among the major causes of crop yield losses around the world. To confer disease resistance, conventional breeding relies on the deployment of single resistance (R) genes. However, this strategy has been easily overcome by constantly evolving pathogens. Disabling susceptibility (S) genes is a promising alternative to R…
Each day, more deaths are being linked to the heat wave that struck the Pacific Northwest this past week, with medical staff who treated people overwhelmed by temperatures well above 100 degrees Fahrenheit (38 Celsius) saying the toll from the extreme weather will keep creeping up.
Wander around a desert most anywhere in the world, and eventually you'll notice dark-stained rocks, especially where the sun shines most brightly and water trickles down or dew gathers. In some spots, if you're lucky, you might stumble upon ancient art—petroglyphs—carved into the stain. For years, however, researchers have understood more about the petroglyphs than the mysterious dark stain, calle
Archaeologists have unearthed a rare trove of more than 80 metal objects in Mississippi thought to be from Hernando de Soto's 16th-century expedition through the Southeast. Many of the objects were repurposed by the resident Chickasaws as household tools and ornaments, an unusual practice at a time when European goods in North America were few and often reserved for leaders.
Research led by Kansas State University's Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with Christopher Sorensen, university distinguished professor of physics, shows potential ways to manufacture graphene-based nano-inks for additive manufacturing of supercapacitors in the form of flexible and printable electronics.
During the rapid development and rolling out of vaccines against COVID-19, researchers have called for an approach of "radical transparency," in which vaccine information is transparently disclosed to the public, even if negative information can decrease vaccine uptake. Consistent with theories about the psychology of conspiracy beliefs, these calls predict…
The global coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome (SARS)–like coronavirus (SARS-CoV-2), presents an urgent health crisis. More recently, an increasing number of mutated strains of SARS-CoV-2 have been identified globally. Such mutations, especially those on the spike glycoprotein to render its higher binding affinity to…
Understanding the trends in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolution is paramount to control the COVID-19 pandemic. We analyzed more than 300,000 high-quality genome sequences of SARS-CoV-2 variants available as of January 2021. The results show that the ongoing evolution of SARS-CoV-2 during the pandemic is characterized primarily…
Viruses of bacteria, also known as bacteriophages, harbor the greatest diversity of DNA modifications identified to date. To fight against restriction endonucleases of their hosts, bacteriophages modify their genomic DNA through introduction of various moieties including amino acids, polyamines, and sugars (1, 2). A series of transformations are involved in…
The systematic variation of diameters in branched networks has tantalized biologists since the discovery of da Vinci's rule for trees. Da Vinci's rule can be formulated as a power law with exponent two: The square of the mother branch's diameter is equal to the sum of the squares of those…
Electron–nuclear double resonance (ENDOR) measures the hyperfine interaction of magnetic nuclei with paramagnetic centers and is hence a powerful tool for spectroscopic investigations extending from biophysics to material science. Progress in microwave technology and the recent availability of commercial electron paramagnetic resonance (EPR) spectrometers up to an electron Larmor frequency…
Endosymbioses have shaped the evolutionary trajectory of life and remain ecologically important. Investigating oceanic photosymbioses can illuminate how algal endosymbionts are energetically exploited by their heterotrophic hosts and inform on putative initial steps of plastid acquisition in eukaryotes. By combining three-dimensional subcellular imaging with photophysiology, carbon flux imaging, a
Standard macroeconomic models assume that households are rational in the sense that they are perfect utility maximizers and explain economic dynamics in terms of shocks that drive the economy away from the steady state. Here we build on a standard macroeconomic model in which a single rational representative household makes…
Infections and inflammation are profoundly influenced by the extracellular matrix (ECM), but their molecular underpinnings are ill defined. Here, we demonstrate that lumican, an ECM protein normally associated with collagens, is elevated in sepsis patients' blood, while lumican-null mice resolve polymicrobial sepsis poorly, with reduced bacterial clearance and greater body…
Mutations in the human peptide:N-glycanase gene (NGLY1), which encodes a cytosolic de–N-glycosylating enzyme, cause a congenital autosomal recessive disorder. In rodents, the loss of Ngly1 results in severe developmental delay or lethality, but the underlying mechanism remains unknown. In this study, we found that deletion of Fbxo6 (also known as…
A fundamental challenge in biology is explaining the evolution of novel phenotypes such as the origins of eusocial behavior. Eusociality—defined by overlapping generations, reproductive division of labor, and cooperative brood care (1)—has evolved at least 17 times in arthropods (2): widespread in the social Hymenoptera (ants, bees, and wasps) and…
For the first time in the UAE, researchers at NYU Abu Dhabi have used nuclear magnetic resonance techniques to determine the structure of a specific nanobody, Nb23, potentially leading to a better understanding of how this small protein derived from an antibody type, found only in camelids (i.e camels, llamas, and alpacas) and sharks, can fight diseases ranging from rheumatoid arthritis, lupus and
To survive life threatening injuries, cancer cells use a technique in which they eat parts of the membrane surrounding them. This is shown for the first time in research from a team of Danish researchers.
Immunotherapy has revolutionized the field of cancer treatment. However, inflammatory reactions in healthy tissues frequently trigger side effects that can be serious. Scientists (UNIGE/Harvard Medical School) have succeeded in establishing the differences between deleterious immune reactions and those targeting tumor cells that are sought after. It appears that while the immune mechanisms are sim
Although intermetallics are attractive for their high strength, many of them are often brittle at room temperature, thereby severely limiting their potential as structural materials. Here, we report on a previously unidentified deformable nanocrystalline CoAl intermetallics with Co-rich thick grain boundaries (GBs). In situ micropillar compression studies show that nanocrystalline CoAl with thick
Understanding and controlling the individual behavior of nanoscopic matter in liquids, the environment in which many such entities are functioning, is both inherently challenging and important to many natural and man-made applications. Here, we transport individual nano-objects, from an assembly in a biological ionic solution, through a nanochannel network and confine them in electrokinetic nanov
The cell cortex is a contractile actin meshwork, which determines cell shape and is essential for cell mechanics, migration, and division. Because its thickness is below optical resolution, there is a tendency to consider the cortex as a thin uniform two-dimensional layer. Using two mutually attracted magnetic beads, one inside the cell and the other in the extracellular medium, we pinch the cort
Live woody vegetation is the largest reservoir of biomass carbon, with its restoration considered one of the most effective natural climate solutions. However, terrestrial carbon fluxes remain the largest uncertainty in the global carbon cycle. Here, we develop spatially explicit estimates of carbon stock changes of live woody biomass from 2000 to 2019 using measurements from ground, air, and spa
The neocortex is stereotypically organized into layers of excitatory neurons arranged in a precise parallel orientation. Here we show that dynamic adhesion both preceding and following radial migration is essential for this organization. Neuronal adhesion is regulated by the Mowat-Wilson syndrome-associated transcription factor Zeb2 (Sip1/Zfhx1b) through direct repression of independent adhesion
We report a novel single-cell whole-genome amplification method (LCS-WGA) that can efficiently capture spontaneous DNA damage existing in single cells. We refer to these damage-associated single-nucleotide variants as "damSNVs," and the whole-genome distribution of damSNVs as the damagenome. We observed that in single human neurons, the damagenome distribution was significantly correlated with th
Millions of putative transcriptional regulatory elements (TREs) have been cataloged in the human genome, yet their functional relevance in specific pathophysiological settings remains to be determined. This is critical to understand how oncogenic transcription factors (TFs) engage specific TREs to impose transcriptional programs underlying malignant phenotypes. Here, we combine cutting edge CRISP
Understanding the evolutionary stability and possible context dependence of biological containment techniques is critical as engineered microbes are increasingly under consideration for applications beyond biomanufacturing. While synthetic auxotrophy previously prevented Escherichia coli from exhibiting detectable escape from batch cultures, its long-term effectiveness is unknown. Here, we report
Development of cortical regions with precise, sharp, and regular boundaries is essential for physiological function. However, little is known of the mechanisms ensuring these features. Here, we show that determination of the boundary between neocortex and medial entorhinal cortex (MEC), two abutting cortical regions generated from the same progenitor lineage, relies on COUP-TFI (chicken ovalbumin
Soft electronics have recently gathered considerable interest because of their biomechanical compatibility. An important feature of deformable conductors is their electrical response to strain. While development of stretchable materials with high gauge factors has attracted considerable attention, there is a growing need for stretchable conductors whose response to deformation can be accurately e
We report a role for the mitochondrial single-stranded DNA binding protein (mtSSB) in regulating mitochondrial DNA (mtDNA) replication initiation in mammalian mitochondria. Transcription from the light-strand promoter (LSP) is required both for gene expression and for generating the RNA primers needed for initiation of mtDNA synthesis. In the absence of mtSSB, transcription from LSP is strongly u
Targeting of the most aggressive tumor cell subpopulations is key for effective management of most solid malignancies. However, the metastable nature of tumor heterogeneity, which allows cells to transition between strong and weak tumorigenic phenotypes, and the lack of reliable markers of tumor-promoting properties hamper identification of the most relevant cells. To overcome these obstacles, we
Homozygosity for the common ACTN3 null polymorphism ( ACTN3 577X) results in α-actinin-3 deficiency in ~20% of humans worldwide and is linked to reduced sprint and power performance in both elite athletes and the general population. α-Actinin-3 deficiency is also associated with reduced muscle mass, increased risk of sarcopenia, and altered muscle wasting response induced by denervation and immob
The plasma membrane shapes and protects the eukaryotic cell from its surroundings and is crucial for cell life. Although initial repair mechanisms to reseal injured membranes are well established, less is known about how cells restructure damaged membranes in the aftermath to restore homeostasis. Here, we show that cells respond to plasma membrane injury by activating proteins associated with mac
In natural anoxic environments, anoxygenic photosynthetic bacteria fix CO 2 by photoheterotrophy, photoautotrophy, or syntrophic anaerobic photosynthesis. Here, we describe electroautotrophy, a previously unidentified dark CO 2 fixation mode enabled by the electrosyntrophic interaction between Geobacter metallireducens and Rhodopseudomonas palustris. After an electrosyntrophic coculture is formed
Root-knot nematodes (RKNs) are plant parasites and major agricultural pests. RKNs are thought to locate hosts through chemotaxis by sensing host-secreted chemoattractants; however, the structures and properties of these attractants are not well understood. Here, we describe a previously unknown RKN attractant from flaxseed mucilage that enhances infection of Arabidopsis and tomato, which resemble
Mesenchymal stem cell (MSC)-based therapy to combat diabetic-associated metabolic disorders is hindered by impoverished cell survival and limited therapeutic effects under high glucose stress. Here, we genetically engineered MSCs with Exendin-4 (MSC-Ex-4), a glucagon-like peptide-1 (GLP-1) analog, and demonstrated their boosted cellular functions and antidiabetic efficacy in the type 2 diabetes m
Transmission-blocking vaccines are urgently needed to reduce transmission of SARS-CoV 2, the cause of the COVID-19 pandemic. The upper respiratory tract is an initial site of SARS-CoV-2 infection and, for many individuals, remains the primary site of virus replication. An ideal COVID-19 vaccine should reduce upper respiratory tract virus replication and block transmission as well as protect again
Methanogens are considered as one of the earliest life forms on Earth, and together with anaerobic methane-oxidizing archaea, they have crucial effects on climate stability. However, the origin and evolution of anaerobic alkane metabolism in the domain Archaea remain controversial. Here, we present evidence that methylotrophic methanogenesis was the ancestral form of this metabolism. Carbon dioxi
Using a method developed for HIV, researchers have identified stable T cell vaccine targets in SARS-CoV-2. These stable targets, known as highly networked epitopes, are highly likely to be stable in different variants of the virus. The results provide a path forward for a broadly protective COVID-19 T cell vaccine.

"Based on what we learned in the survey, there are some simple measures, such as providing a borrowed wheelchair to people so they have mobility while their chair is being repaired, that could reduce the adverse consequences," said Dr. Dyson-Hudson. "Other facilitators include increasing the speed of repairs, training people in wheelchair maintenance, and routinely scheduling follow-up appointment
Engineers at the University of California, Berkeley, have created an insect-scale robot that can swerve and pivot with the agility of a cheetah, giving it the ability to traverse complex terrain and quickly avoid unexpected obstacles. Small, robust robots like these could be ideal for conducting search and rescue operations or investigating other hazardous situations, such as scoping out potential
Some three quarters of the biomass in hop plants used in beer-making ends up in landfills. But a group of Japanese researchers has developed a technique that 'upcycles' that waste hop into cellulose nanofibers (CNFs). A paper describing the technique was published in the journal ACS Agricultural Science & Technology on June 11, 2021.
Would you be more willing to get vaccinated against the COVID-19 virus if you could participate in a lottery for cash and prizes? The answer was surprisingly no, according to Boston University School of Medicine (BUSM) researchers who found that Ohio's "Vax-a-Million" lottery-based incentive system, intended to increase COVID-19 vaccination rates, was not associated with an increase in COVD-19 vac
A new study found that while 43 states (out of 51, including all 50 states and Washington, D.C.) created a committee to develop a vaccine distribution plan, only 20 plans mentioned using a health equity committee to assist with plan development.

These topics are explored in selected member-submitted abstracts from the 2020 Vizient® Connections Education Summit that appear in a special supplement to the July/August 2021 issue
Their conclusion: in extremely cold regions, it can be considerably more efficient to attach the PV modules directly to the electrolyser, i.e. to thermally couple them. This is because the waste heat from the PV modules increases the efficiency of electrolysis in this environment. The results of this study are also relevant for other cold regions on Earth, such as Alaska, Canada, and high mountain
Researchers from 12 Spanish hospitals took part with the aim of uncovering clinical and prognostic characteristics in solid organ recipients with COVID-19. The conclusions underscore the need for strict preventive measures in the initial period after transplantation.
The molecule, known as DAF, increases disease severity in mice upon infection with Influenza A virus, the most prevalent cause of the seasonal flu. Understanding this novel virulence mechanism of influenza and identifying the intrinsic factors that determine disease severity opens new possibilities for finding therapeutic targets for resilience to viral infections.
When the U.S. Space Force's Tactically Responsive Launch-2 (TacRL-2) mission launched from Vandenberg Space Force Base on June 13, it carried a payload designed and built in record time by Lawrence Livermore National Laboratory (LLNL).
When the analysis of digital data reaches its limits, methods that focus on observations made by individuals can be useful. In contexts such as the coronavirus pandemic, a method called human social sensing can elicit information that is difficult to obtain from digital trace data. Prof. Frauke Kreuter at Ludwig-Maximilians-Universitaet (LMU) in Munich is now using this method with the global "Cov

They were able to decode the structure of the enzyme responsible for the ethane fixation. The structure highlights so
Originally discovered as a bacterial mode of defense against invading viruses, the remarkable ability of CRISPR-Cas9 to modify specific locations of DNA has made it a researcher favorite among gene editing tools. The ongoing effort to explore further possibilities of the CRISPR-Cas9 system is ushering in newer developments to this tool. In one of the latest refinements of the technique, as illustr
Money, money, money … in the music business, there seems to be little left for the songwriters that fuel it. ABBA co-founder Björn Ulvaeus calls for the industry to support its most valuable asset, breaking down how the streaming revolution impacts creator royalties, careers and craft — and outlines what can be done to truly thank artists for the music.
Maternal exposure to air pollution during pregnancy has often been linked to adverse effects on the health of the newborn. However, there are very few studies on the subject. A study conducted at the UPV/EHU has just concluded in a paper published in the journal Environmental Research that the stages most sensitive to air pollution are the early and late months of pregnancy.
Migraine is one of the largest causes of disability in the world. Existing treatments are often not enough to offer full relief for patients. A new study published in The BMJ demonstrates an additional option patients can use in their effort to experience fewer migraines and headaches – a change in diet.
The EOLO research group of the UPV/EHU-University of the Basque Country has confirmed the increase in the power flow of the waves in the Bay of Biscay from 1900 onwards.

UC San Diego studies using human cell lines and tumors grown in mice provide early evidence that inhibiting RNA-binding proteins, a previously overlooked family of molecules, might provide a new approach for treating some cancers.
Researchers believe the liver may hold the key to new, preventative Type 2 diabetes treatments. This year marks the 100th anniversary of the discovery of insulin , a scientific breakthrough that transformed Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, from a terminal disease into a manageable condition. Today, Type 2 diabetes is 24 times more prevalent than Type
Just days after adding an expression of concern to a paper published last week claiming that two people died from COVID-19 vaccinations for every three cases the vaccines prevented, the journal Vaccines has retracted the paper. As we have previously noted: The authors, including Harald Walach, who was also co-author of a just-published paper in … Continue reading
During the course of evolution, animals have adapted to the particular demands of their local environments in ways that increased their chances of survival and reproduction. This is also true of diverse aspects of the sensory systems that enable species to perceive their surroundings. In the case of the visual system, these adaptations have shaped features such as the positioning of the eyes and t
The flavor of a tomato is an interaction between its taste and aroma. Now, researchers from Japan and the United States have revealed that the pigments that determine the colors of tomatoes also affect their flavor.
In the 19th century, the notorious pathogen Phytophthora infestans caused a large famine in Ireland and other parts of Western Europe. To this day, it continues to pose a major threat to global food production. It has long been a mystery how this microscopically small organism and other members of the Phytophthora genus mechanically gain entry through the protective layer on the leaves of crops. I
More efficient use of phosphorus fertilizers would make it possible to meet food demand in 2050, without using more of the world's land for agriculture. This is what environmental scientists José Mogollón and colleagues have discovered by working out various future scenarios for food production and trade. This could be achieved with only 7% more phosphorus fertilizer. And if our future is more sus
Guadalupe fur seals (Arctocephalus townsendi) have established a large resting colony in the Gulf of California—bringing the total number of sites where this endangered species now occurs to just four. This new haul-out was discovered on El Farallón de San Ignacio Island, along the mainland coast of Mexico, according to researchers from Mexico and the University of British Columbia.
Any cat lover who has watched an allergic friend react to a beloved pet knows the dark powers that lurk in that luxurious feline fur. Within minutes, an allergic human exposed to a cat can begin sneezing and wheezing. Eyes water and itch. The misery is obvious.
In his Ph.D. thesis, EPFL researcher Martí Bosch proposes a method for spatially quantifying the impact of mitigation measures—planting green spaces and using different building materials—on the urban heat island effect.
Plastics are a growing problem for natural ecosystems around the globe, and in particular for our marine and freshwater environments. Rivers are the leading source of plastic pollution, as it has been estimated that they deliver several million metric tons of plastic annually to our oceans from poor land-based waste management. The problem is that the estimates made for plastics flowing from the r
NIMS and Harvard University jointly developed a technique capable of measuring the viscosity of both liquids and gasses using the same device. This device can be used to identify unknown fluids based on their viscosities and may potentially be used to analyze biological fluids (e.g., breath and blood) for health monitoring and medical checkups. The device may also be used to investigate the physic
Microorganisms produce natural products, for example, as disease-causing virulence factors or as defense substances against predators and competitors. A team led by Dr. Robin Teufel and first author Ying Duan from the Institute of Biology II at the Faculty of Biology of the University of Freiburg, together with researchers from the University of Bonn, have now discovered a novel enzyme that is cru
New research published in The Journal of Physiology shows that researchers have successfully repurposed two existing medications to reduce the severity of sleep apnoea in people by at least 30 per cent.
When extreme heat becomes more frequent and temperatures remain high for extended periods of time, as it is currently in Canada and in the American Northwest, physiological stress increases in humans, animals and crops. Prof. Senthold Asseng, director of the World Agricultural Systems Center at the Technical University of Munich (TUM), provides an overview of thresholds and adaptation strategies.
As the health of Australia's environment continues to decline, the federal government is wagering on the ability of private markets to help solve the problem. So is this a wise move? The evidence is not at all encouraging.
Researchers have screened thousands of drug and chemical molecules and identified a range of potential antivirals that could be developed into new treatments for COVID-19 or in preparation for future coronavirus outbreaks.
The muskrat, a stocky brown rodent the size of a Chihuahua—with a tail like a mouse, teeth like a beaver and an exceptional ability to bounce back from rapid die-offs—has lived for thousands of years in one of Earth's largest freshwater deltas, in northeastern Alberta, Canada.
Researchers from the National Time Service Center (NTSC) of the Chinese Academy of Sciences have proposed a new method to realize absolute calibration of multi-mode satellite navigation receiver delay.
Nyanlända och etablerade svenskar har träffats i ett vänskapsprojekt i Umeå. Men skillnad i gruppernas livsvillkor ställer sig ibland i vägen för vänskapen. De flesta kan nog skriva under på att vänskap är viktigt. Men kanske blir det särskilt tydligt för den som kommer ensam till ett nytt land. Att ha eller inte ha vänner kan göra stor skillnad för den som försöker starta ett nytt liv på en plat
I would like to recommend this piece at Stat about the details of the Biogen aducanumab approval. It's behind the paywall, but it's a deeply reported piece from Adam Feuerstein, Matthew Herper, and Damian Garde about how in 2019 Biogen launched an effort to get their apparently failed drug approved by the FDA anyway. They called it "Project Onyx", renamed from the original "Project Phoenix" after
We generated a mouse model for a subgroup of schizophrenia patients by feeding Glo1 knockout mice VB6-deficent diets (KO/VB6(-)). We found that the KO/VB6(-) mice accumulated methylglyoxal (MG) in the brain and showed schizophrenia-like behavioral impairments. Furthermore, we found aberrant gene expression related to mitochondria function in the prefrontal cortex (PFC) of the KO/VB6(-) mice. Final
Kyushu University researchers found that the main gene that causes Rett syndrome, MeCP2, controls the differentiation pattern of neural stem cells through the microRNA miR-199a. Dysfunction in MeCP2 or miR-199a cause neural stem cells to produce more astrocytes than neurons. Furthermore, the researchers found that miR-199a mediates the production of Smad1, a downstream transcription factor of bone
In an Australian world-first, researchers have successfully repurposed two existing medications to reduce the severity of sleep apnoea in people by at least 30 per cent. Affecting millions around the world, sleep apnoea is a condition where the upper airway from the back of the nose to the throat closes repetitively during sleep, restricting oxygen intake and causing people to wake as often as 100
Researchers from University of Tsukuba and University of Florida have found that pigments controlling the color of tomatoes also play a role in determining their flavor. By analyzing the pigment profiles of 157 different tomato varieties, the team showed that fruit with high chlorophyll levels had a higher sugar content, and that the carotenoid, prolycopene, is associated with an abundance of arom
Extreme longevity likely will continue to rise slowly by the end of this century, according to new research, with estimates showing that a lifespan of 125 years, or even 130 years, is possible. The number of people who live past the age of 100 has been on the rise for decades, up to nearly half a million people worldwide. There are, however, far fewer "supercentenarians," people who live to age 1

Raging wildfires pump tiny pollutants into the air, degrading air quality across vast areas. These pollutants, or aerosols, can soar high into the atmosphere at the tops of smoke plumes or creep close to the ground where they pose a health risk to humans. To accurately track these pollutants and their spread, scientists need accurate monitoring systems that can see the whole picture.
A new study offers the first genome-wide evidence for the functional importance of unusual DNA structures. Some regions of the human genome where the DNA can fold into unusual three-dimensional structures called G-quadruplexes (G4s) show signs that they are preserved by natural selection. When G4s are located in the regulatory sequences that control how genes are expressed or in other functional,
When a volcano violently erupts, a plume of ash and gases spews skyward. The hot slurry quickly rises into the atmosphere, where various atmospheric dynamics interact to shape the volcanic cloud's composition, height, and radiative properties. Volcanic clouds reflect solar radiation, cool Earth, cause weather extremes, and delay global warming, but scientists have long wondered exactly how volcani
Increased local tourism and toxic substances transported to glaciers from distant locales can contribute to high concentrations of human-sourced metal pollution in snow and streams around Mount Everest that is likely degrading the quality of water used by thousands of residents and climbers.
The federal government has opposed a recommendation by a United Nations body that the Great Barrier Reef be listed as "in danger". But there's no doubt the natural wonder is in dire trouble. In new research, my colleagues and I provide fresh insight into the plight of many coral species.
Scientists from British Antarctic Survey (BAS), Scottish Association for Marine Science (SAMS), and international collaborators have this week published the first detailed research on the sounds made by southern right whales on their high latitude feeding grounds at South Georgia.

The cluster—which is in the constellation Tucana (the Toucan)—contains a multitude of stars, many of which are scattered across this striking image.
While heatwaves are quite common during the summer months, the scorching heatwave hitting parts of western Canada and the U.S. has been particularly devastating—with temperature records shattered and hundreds of people falling victim to the extreme heat.
Indiana University School of Medicine researchers are developing a new, noninvasive brain stimulation technique to treat neurological disorders, including pain, traumatic brain injury (TBI), epilepsy, Parkinson's disease, Alzheimer's disease and more.
The weather forecast says it's going to be hot. Air temperatures are projected to soar into the high 90s or even reach the 100s. But in some places on the ground, it can feel a lot hotter—like the inside of an oven.
As a parent, noone has to tell you how important STEM subjects are for your children's early development. That's because studies show an early education in STEM subjects help children develop the kinds of skills necessary to succeed in the jobs that are leading the future . Research also indicates early childhood is the critical window for development — not only for cognition, but also for behavi
The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to examine other ways to grapple with the issue of food waste disposal.
One summer night in August, 1935, a young Soviet miner named Alexei Stakhanov managed to extract 102 tonnes of coal in a single shift. This was nothing short of extraordinary (according to Soviet planning, the official average for a single shift was seven tonnes).
Exactly 300 years ago, in 1721, Benjamin Franklin and his fellow American colonists faced a deadly smallpox outbreak. Their varying responses constitute an eerily prescient object lesson for today's world, similarly devastated by a virus and divided over vaccination three centuries later.
For more than a year and a half, the SARS-CoV-2 pandemic has kept the world locked down. Schools, universities, cafés and restaurants, cultural institutions and stores have been closed for long stretches of 2020 and 2021. In many parts of the world, travel has slowed to a crawl and sometimes stopped completely. While the number of flights is climbing as some restrictions are lifted, they remain si
Varför gör vissa mindre hållbara val i vad de konsumterar? En delförklaring kan vara att de helt enkelt saknar personer i sin omgivning som uppmuntrar (eller tjatar) på dem. Det menar forskare från Örebro universitet, som har undersökt frågan.
Emil i Lönneberga utmålas ofta som en busunge på kant med vuxenvärlden. Men Emils hyss kan lika gärna förstås som solidariska handlingar, menar litteraturprofessor Björn Sundmark som hittat en ny ingång till Astrid Lindgrens författarskap. – Att Emil ses som en illbatting är ju bara vad som syns på ytan. Det finns i själva verket en stark solidaritet inom familjen men även till andra i socknen, s

Historically people shifted from one sector to another when automation reduced the number of workers needed. This time is different though because there is no fourth sector into which people can shift. Also nearly all good paying jobs are high skill. It is no longer possible to go from farming to the factory where you are trained for a few days or weeks and get a decent wage. Nowadays one require
Retraction Watch readers may recall the work of Elizabeth Suelzer, a librarian at the Medical College of Wisconsin in Milwaukee.
