In order to help stave off heart failure, new research suggests that most people around the world would benefit from drinking an extra glass of water . It turns out that getting properly hydrated — that means reaching and maintaining appropriate levels in the long term — can reduce the risk of developing heart failure, according to research presented at a European Society of Cardiology conference
Lab Wagyu Scientists at Osaka University in Japan have managed to print lab-grown steak that they say greatly resembles products made from the world-renowned breeds of Wagyu beef cattle — an environmentally conscious and sustainable alternative to a genuine delicacy. The team harvested two types of stem cells from Wagyu cows, incubated them, and then converted them into muscle, fat, and blood ves
Streetlights—particularly those that use white light-emitting diodes (LEDs)—not only disrupt insect behavior but are also a culprit behind their declining numbers, a new study carried out in southern England showed Wednesday.
Water is the most abundant yet least understood liquid in nature. It exhibits many strange behaviors that scientists still struggle to explain. While most liquids get denser as they get colder, water is most dense at 39 degrees Fahrenheit, just above its freezing point. This is why ice floats to the top of a drinking glass and lakes freeze from the surface down, allowing marine life to survive col
"The distinction between the past, present and future is only a stubbornly persistent illusion," Albert Einstein wrote. Perhaps this is nowhere more evident than in protein evolution, where past and present versions of the same enzyme exist in different species today, with implications for future enzyme design. Now, researchers have used evolutionary "time travel" to learn how an enzyme evolved ov
In 2018, GE unveiled its Haliade-X turbine, and it has since been the largest and most powerful offshore wind turbine in the world. At 853 feet tall and with a rotor measuring 722 feet across, a single rotation of its blades can power a home for two days (that's a home in the UK, not the US; homes here tend to be bigger energy hogs). Last year, the Haliade-X prototype located in the Netherlands s
'Eco-friendly' lights found to be worse than sodium ones – but both contribute to insect decline, says study "Eco-friendly" LED streetlights produce even worse light pollution for insects than the traditional sodium bulbs they are replacing, a study has found. The abundance of moth caterpillars in hedgerows by rural roads in England was 52% lower under LED lights and 41% lower under sodium lights
Mass Casualties As Florida's fragile ecosystems crumble under the ravages of climate change, beloved local wildlife is finding it hard to survive. That became especially evident when the bodies of 677 manatees washed up along the state's east coast between December 2020 and May 2021, as the Orlando Sentinel reports . The winter is usually tough for the local manatee population, but experts examin
According to a recent survey of finance industry executives by consulting giant Deloitte, digital assets will likely replace fiat currencies in five to ten years — and banks should take notice. "Deloitte's 2021 Global Blockchain Survey affirms that banks should embrace their inevitable digital future," the report reads. "In a seismic shift, financial leaders increasingly see digital assets as the

Skeleton of hunter-gatherer found in Leang Panninge cave sheds light on ancient human migration Archaeologists have discovered ancient DNA in the remains of a woman who died 7,200 years ago in Indonesia, a find that challenges what was previously known about migration of early humans. The remains, belonging to a teenager nicknamed Bessé, were discovered in the Leang Panninge cave on the Indonesia
Our world and the self are constructions of the brain, a pioneering neuroscientist argues For every stoner who has been overcome with profound insight and drawled, "Reality is a construct, maaan," here is the astonishing affirmation. Reality – or, at least, our perception of it – is a "controlled hallucination", according to the neuroscientist Anil Seth. Everything we see, hear and perceive aroun
Covid response minister says it would be a waste to stop aiming for elimination after plan was questioned by foreign media See all our coronavirus coverage New Zealand's Covid response minister says the country will not "throw in the towel" with its elimination strategy, as cases continue to rise. New Zealand announced 63 new cases of Covid-19 on Wednesday, bringing the total to 210 cases. It is
30-Year Flush In order to safely dispose of the radioactive water building up and threatening to overflow at the destroyed Fukushima Daiichi nuclear power plant, the Tokyo Electric Power Company Holdings (TEPCO) has announced plans to drill an undersea tunnel that will allow it to dump the contaminated water at a moderate distance from the shore. The idea is for the kilometer-long (0.6 miles) tun
L osing a war undermines the public's trust in any leader. But the setback causing the most damage to Joe Biden's political standing likely isn't the U.S. military defeat in Afghanistan—it's the frustrating home-front struggle against the resurgent coronavirus pandemic. Support for Biden's performance as president has tumbled in the most recent batch of polling. For the first time since he took o
Hello There A team of scientists was shocked when they accidentally stumbled upon an "exceptionally large" mass of coral in the Great Barrier Reef that they believe to be more than 400 years old. The new coral is likely the widest of its type, according to research published in the Nature journal Scientific Reports last week. And, in a surprising twist, the bus-sized coral was shockingly healthy
Project Jarvis Blue Origin is making headwind on developing a fully reusable rocket stage designed to launch its New Glenn rocket, according to images taken near the test site and published by Ars Technica today. The test tank bears a striking resemblance to SpaceX's Super Heavy booster prototypes — which is striking, because the two space companies are currently embroiled in an increasingly bitt
Hammer Vision Among the local Texans who live near SpaceX's Boca Chica Starbase facility, one of the biggest complaints is the fact that the company frequently blocks the highway while shipping rocket parts or shuts it down altogether for launches, cutting off would-be travelers from the area. As the saying goes, to the man with a tunnel-digging company, everything looks like, well, a great spot
An alleged email leak appears to show the United Launch Alliance, a prominent SpaceX competitor, plotting to spread damaging conspiracy theories about SpaceX CEO Elon Musk. The authenticity of the emails has yet to be confirmed, though Ars Technica is reporting that they "appear to be legitimate." And ULA spokeswoman Jessica Rye told Futurism that "we will not comment at this time but are taking

For most of human history, the majority of people died of infectious disease. Scourges like tuberculosis, typhoid, plague, smallpox, and (in some places) malaria carried most people to their graves, many as infants or children. As public health and biomedicine advanced, cancers and organ diseases replaced microbes as the main causes of mortality. The control of infectious disease, and consequent

More Into Vaping The Chinese tech and e-commerce giant Alibaba recently announced a plan to roll out 1,000 delivery robots throughout the country this year — and it's taking some jabs at the human delivery workers they'd be replacing. The delivery bot rollout is meant to better tackle the "last mile problem" of delivery logistics, according to The Register , in which an otherwise smooth process c
It's long been difficult for Americans with disabilities to vote. Inaccessible paths are an obstacle to people who use wheelchairs. Long lines are a huge hurdle to people with chronic pain. Voting machines without audio or large-print ballots are an impediment to those who are blind or who have low vision. But last year, something different happened: As states passed pandemic-driven reforms to ma
Anomalous Health Incidents A suspected new case of the mysterious "Havana syndrome" has reportedly delayed US vice president Kamala Harris' visit to Vietnam, ABC News reports .

While we don't have a direct confirmation that the incident has any direct
Car engineer and critic Sandy Munro recently got a demo of Ford's hands-free driving feature BlueCruise. And he wasn't exactly impressed. In a recent video, Munro had a chat with lead engineer Chris Billman, chief engineer at Ford Driver Assist Technologies, while testing out the new feature. "All in all, it was OK," Munro told Billman in the video after taking the car for a ride. "But I guess I'
President Joe Biden has been giving climate advocates heartburn. In April, soon after rejoining the Paris Agreement, he set a goal: The United States would cut its greenhouse-gas pollution by 50 percent from 2005 levels by 2030. The White House promised that "a careful interagency process" had produced that goal, and at least a dozen reports from outside scholars and nonprofits argued that such a
Surrounding Earth is a powerful magnetic field created by swirling liquid iron in the planet's core. Earth's magnetic field may be nearly as old as the Earth itself – and stands in stark contrast to the Moon, which completely lacks a magnetic field today. But did the Moon's core generate a magnetic field in the past? In the 1980s, geophysicists studying rocks brought back by Apollo astronauts con
Researchers—led by the University of York's BioArCh team—developed a new approach to analyze amino acids, the building blocks of proteins, from 17 adult skeletons found in the aftermath of the eruption of Vesuvius in 79 AD.
Our June Insights puzzle added a few twists to a classic puzzle made famous by Martin Gardner in his 1965 Scientific American column and later published in the book The Colossal Book of Short Puzzles and Problems. In our version, a swimmer at the center of a circular lake of radius 3.5 is attempting to escape a bear hunting him from the shore. The bear doesn't swim but can run along the… Source
Sleep is essential to how we function, and one of its more important aspects is how it consolidates memories. The brain decides for us which memories we ought to keep. It does so based upon the strength of an emotional experience, either positive or negative. New research suggests that during NREM sleep, our brain is more likely to store positive memories. Sleep feels great. After a long day, the
Bagel Boosters In an unfortunate turn of events, rocket companies are running low on liquid oxygen (LOX), a cryogenic oxidizer used to propel rockets into orbit. The reason? The ongoing — and now severely worsening — COVID-19 pandemic. That's because hospitals are using the stuff to keep patients alive as well as for water treatment, according to Insider . SpaceX president Gwynne Shotwell noted d
A trio of researchers from the University of Cambridge working with a colleague from the University of Tartu has found possible evidence of multiple opportunities for early humans to migrate out of Africa to the Arabian Peninsula prior to the mass migration that occurred approximately 65,000 years ago. In their paper published in the journal Nature Communications, the group describes mapping clima
The mystery of what creates the rare, healthy sugar found in stingless bee honey, has been solved by researchers at The University of Queensland, in collaboration with Queensland Health Forensic and Scientific Services.
Inspired by a Guardian article, the theatre's surreal and spellbinding show AI is a collaboration between humans and the system GPT-3 Last autumn, a deep-learning computer programme wrote an essay for the Guardian . The GPT-3 system argued that humans had nothing to fear from robots. Kwame Kwei-Armah, artistic director of the Young Vic, read it and felt inspired. Could there be a future in creati
Lizards and snakes are a key component of most terrestrial ecosystems on earth today. Along with the charismatic tuatara of New Zealand (a "living fossil" represented by a single living species), squamates (all lizards and snakes) make up the Lepidosauria—the largest group of terrestrial vertebrates in the planet today with approximately 11,000 species, and by far the largest modern group of repti
Early 19th century heart-shaped map remains a popular allegory of love. Looking beyond its shape, the map shows the social restrictions of its time.

On a muggy spring night in 2016, the chemist Bernd Schöllhorn was tromping alone through a forest in northern Vietnam . Into the inky darkness, he raised a black light—and saw an extraordinarily bright shape winking at him in eerie shades of yellowish green. "I thought it was somebody else," Schöllhorn, a researcher at the University of Paris, told me. But when he cut his own light, the stranger'
On August 9, faculty and administrators in the Clark County School District—which serves Las Vegas and surrounding areas—welcomed students back to classrooms for full-time in-person instruction. And, at the beginning, leaders of the nation's fifth-largest school district were cautiously optimistic; aside from difficulty with air-conditioning in some buildings, the first day went off without issue
Hospitals received letters threatening large fines after they installed their own onsite O2 plants in response to shortages In March 2020, Benjamin Espinoza Zavala saw an entire floor of his small hospital in Guanajuato, central Mexico, converted into Covid-19 wards. The hospital's need for oxygen soared. Deliveries from CryoInfra, part of the Grupo Infra group , occasionally slowed to once every
A CT scan of the skull of a long-necked plesiosaur shows the cranial architecture of these long-extinct marine reptiles didn't evolve much over 22 million years that they lived during the Cretaceous time.
Cambridge astronomers identify new hycean class of habitable exoplanets, which could accelerate search for life Signs of life beyond our solar system may be detectable within two to three years, experts have said after rethinking the kinds of planets that may be habitable. Researchers have mostly looked for planets of a similar size, mass, temperature and atmospheric composition to Earth. But Uni
In recent years, several computer scientists and physicists have been exploring the potential of quantum-enhanced machine learning algorithms. As their name suggests, quantum machine learning approaches combine quantum algorithms with machine learning techniques.
In a paper published August 23, authors Cameron Pahl and Luis Ruedas, of Portland State University, show that Allosaurus, a large carnivorous dinosaur from the Jurassic that has long been thought to be a top predator, could probably have acquired most of its calories by scavenging on the carcasses of enormous sauropod herbivores that lived alongside it. Pahl noted that "This new perspective may ov
For home gardeners and farmers, herbivorous insects present a major threat to their hard work and crop yields. The predator insects that feed on these bugs emit odors that pests can sense, which changes the pests' behavior and even their physiology to avoid being eaten. With bugs becoming more resistant to traditional pesticides, researchers now report they have developed a way to bottle the "smel
The Congo basin is home to the world's second-largest rainforest, whose 500 million acres have been slowly drying out for the last four decades. To figure out why the dry season is getting longer, scientists have been asking: What makes it rain in the Congo rainforest?
In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world's most common and cheap metal ions—sodium. The results show that the capacity can match today's lithium-ion batteries.
President Biden's early climate efforts prioritized popular actions: rejoining the Paris agreement, purchasing clean energy and vehicles, and eliminating fossil fuel subsidies. But the administration's strategies to drive the nation toward net-zero emissions also lean heavily, if less obviously, on a touchier area: capturing or removing huge amounts of the carbon dioxide driving global warming.

Scientists have traced the genetic makeup of lake trout, a feat that should boost efforts to rebuild populations of the prized fish in the Great Lakes and other North American waters where they've been hammered by invasive species, overfishing and pollution, officials said Tuesday.
During the Soviet days, movies promoted socialist ideology. Today, films serve up cautionary tales about revolution and insurrection. However, Russian cinema is more than propaganda; the films are as rich as the country's history. In 1930, the renowned Soviet filmmaker Sergei Eisenstein traveled to New York City in the hope of striking a production deal with Paramount Pictures. While executives w
Many of the products we encounter daily—from deodorant to pesticides to paint—release molecules that drift through the air. Breathing in enough of the wrong ones can cause serious and potentially long-term health problems. However, it can be hard to estimate exposure because current devices are limited in what they can detect. Today, researchers report development of a new personal air-sampling sy
When I was 19—long before I ever thought I would land a career writing about space—I dreamed I was standing on the surface of Mars, looking over a rusted desert dotted with rocks, stuck in a perpetual lukewarm dusk, transfixed by the desolation. After soaking everything in for what seemed like hours, I looked up and saw a space station hanging in the sky. I decided to fly up there using some kind

Optoelectronics—technology that gives off, detects, or controls light—are used everywhere in modern electronics and include devices such as light-emitting diodes (LEDs) and solar cells. Within these devices, the movement of excitons (pairs of negative electrons and positive holes) determines how well the device performs.
A team from the University of Illinois has developed a model that treats photosynthesis as a dynamic process rather than an activity that either is or is not happening. This allowed the group to examine the impacts of the many fluctuations in light that crop leaves experience due to intermittent clouds, overlying leaves and the sun's daily passage across the sky. In today's densely planted crops,
Science is not just something we do at school or professionals undertake in labs. It is at the heart of how everything works. With the development of applied scientific principles, science enables us to not only understand how things work but how to make use of that understanding in the technology that supports our everyday lives. In this excerpt from their new book, How it All Works , Adam Dant
In high school, Daniel Stein built a solar-powered car and drove it across the country.

A Wistar study shows the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth.
Recent archaeogenetic studies have shown that human movements like migrations and expansions played a major role in driving the spread of cultures and genes in ancient Europe. However, it is only now with detailed regional studies and dense sampling that researchers start to better understand the magnitude, rate and social implications of these changes.
Mantis shrimp pack the strongest punch of any creature in the animal kingdom. How mantis shrimp produce these deadly, ultra-fast movements has long fascinated biologists. Now, an interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these pugnacio
New research offers insight into how to treat endometriosis. The researchers performed genetic analyses of humans and rhesus macaques to identify a specific gene, NPSR1, that increases risk of suffering from endometriosis. The results reveal a potential new nonhormonal drug target that may lead to improved therapy.
Knowing where cold water is likely to stay cold is critical for conservation. But "cold" is more than just a number on a thermometer. Dams do not adequately support cold-water ecosystems, finds a new study.
For home gardeners and farmers, herbivorous insects present a major threat. The predator insects that feed on these bugs emit odors that pests can sense, which changes the pests' behavior and physiology to avoid being eaten. With bugs becoming more resistant to traditional pesticides, researchers now report they have bottled the 'smell of fear' produced by predators to repel and disrupt insects na
An international study found that intact tropical mountain (or montane) forests in Africa store around 150 tons of carbon per hectare. This means that keeping a hectare of forest standing saves CO2 emissions equivalent to powering 100 homes with electricity for one year.
A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion.
People whose scores on a dementia risk test indicated a less brain-healthy lifestyle, including smoking, high blood pressure and a poor diet, may also have the following: lower scores on thinking skills tests, more changes on brain scans and a higher risk of cognitive impairment, according to a new study.
Exposure to wildfire smoke during pregnancy increases the risk that the baby will be born too early, a new study shows. The study, published in Environmental Research , finds there may have been as many as 7,000 extra preterm births in California attributable to wildfire smoke exposure between 2007 and 2012. These births occurred before 37 weeks of pregnancy when incomplete development heightens
Carbon dioxide from the atmosphere dissolves in waterways, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxide later. Now, researchers have developed tiny 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so
Tyrannosaurus rex, the fearsome predator that once roamed what is now western North America, appears to have had an East Coast cousin. A new study describes two dinosaurs that inhabited Appalachia — a once isolated land mass that today composes much of the eastern United States — about 85 million years ago: an herbivorous duck-billed hadrosaur and a carnivorous tyrannosaur.
Pulling heat-trapping carbon dioxide out of the air and turning it into useful products, a concept called carbon capture and utilization, has the potential to offer both environmental and economic benefits.
Let's face it. Cannabis is more popular (and some would say cooler ) than ever. The use of marijuana and CBD products, both medically and recreationally, is fast becoming the norm. However, explaining the intricacies of the cannabis plant and the products that are made from it can be difficult. Fortunately, a new company called Goldleaf is producing slick-looking cannabis-themed charts and infogr
New research suggests that men and women worry about the impact of COVID-19 in far different ways. For example, men are more likely to be concerned about financial consequences from COVID-19 while women report greater fear and more negative expectations about health-related outcomes.
A new analysis suggests that U.S. workers in industries that expose them to weather conditions work fewer hours per day when temperatures surpass 90 degrees Fahrenheit — but only during periods of economic growth.
The 1992 original Candyman film, my favorite piece of horror cinema from that decade, is about an interloper. Helen Lyle (played by Virginia Madsen), a plucky, white graduate student researching urban legends in Chicago, is drawn to the city's dilapidated Cabrini-Green projects , where she learns of a monster named the Candyman: a vengeful Black ghost who appears if you say his name five times wh
Each year in the United States, millions of tons of plastic waste are discarded and not recycled, leading to serious environmental problems. In an effort to help keep this waste from ending up in the environment, engineers at the University of Missouri are partnering with Dow and the Missouri Department of Transportation (MoDOT) to test mixing plastic waste into the asphalt pavement mixtures for p
Studies show that anti-Korean sentiment in Japan has grown steadily in the past decade, despite the growing acceptance of more visibly "foreign" Southeast Asian migrants in Japan. A University of Notre Dame researcher conducted two years of ethnographic fieldwork in a historic Korean ghetto in Osaka, Japan, to shed light on the legacy of discrimination that third- and fourth-generation Korean mino
Technology is rapidly evolving across many disciplines. Ground-breaking results are often obtained when new technology enables novel approaches or when technologies are transferred from other fields of research. In a recent review article, Dr. Esther Singer and colleagues explored novel and emerging technologies in relation to plant microbiome research.
The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically studied the country's historical earthquakes.
Busy Bees New York City office buildings are scrambling for new ways to lure tenants — and their employees — back to in-person work while the coronavirus pandemic rages on. And among their top strategies is adding amenities reminiscent of the more nature-adjacent lifestyles that some workers may have experienced during the last year and a half such as, oddly enough, rooftop beekeeping classes, Th

Researchers at the Institute of Molecular Biology (IMB) and Johannes Gutenberg University Mainz (JGU) have developed a method to engineer new functionalities into cells. The results were published today in the journal Cell in the article "Dual film-like organelles enable spatial separation of orthogonal eukaryotic translation."
The hallmark of severe COVID-19 is an uncontrolled inflammatory response, resulting from poorly understood immunological dysfunction. We hypothesized that perturbations in FoxP3+ T regulatory cells (Treg), key enforcers of immune homeostasis, contribute to COVID-19 pathology. Cytometric and transcriptomic profiling revealed a distinct Treg phenotype in severe COVID-19 patients, with an…
The announcement by the Biden Administration to reengage the Paris climate process and lower US greenhouse gas (GHG) emissions 50% by the end of this decade is an essential development in the global effort to avoid the worst impacts of climate change (1). However, promises to reduce US GHG emissions…
The trace element zinc is essential for many aspects of physiology. The mitochondrion is a major Zn2+ store, and excessive mitochondrial Zn2+ is linked to neurodegeneration. How mitochondria maintain their Zn2+ homeostasis is unknown. Here, we find that the SLC-30A9 transporter localizes on mitochondria and is required for export of…
Antigen (Ag) crosslinking of immunoglobulin E–receptor (IgE-FcεRI) complexes in mast cells stimulates transmembrane (TM) signaling, requiring phosphorylation of the clustered FcεRI by lipid-anchored Lyn tyrosine kinase. Previous studies showed that this stimulated coupling between Lyn and FcεRI occurs in liquid ordered (Lo)-like nanodomains of the plasma membrane and that Lyn…
Increasing attention has been paid to roles of tripartite motif–containing (TRIM) family proteins in cancer biology, often functioning as E3 ubiquitin ligases. In the present study, we focus on a contribution of TRIM47 to breast cancer biology, particularly to endocrine therapy resistance, which is a major clinical problem in breast…
The fidelity of protein transport in the secretory pathway relies on the accurate sorting of proteins to their correct destinations. To deepen our understanding of the underlying molecular mechanisms, it is important to develop a robust approach to systematically reveal cargo proteins that depend on specific sorting machinery to be…
Pigment organelles of vertebrates belong to the lysosome-related organelle (LRO) family, of which melanin-producing melanosomes are the prototypes. While their anabolism has been extensively unraveled through the study of melanosomes in skin melanocytes, their catabolism remains poorly known. Here, we tap into the unique ability of crab spiders to reversibly…
Neuromorphic computing—which aims to mimic the collective and emergent behavior of the brain's neurons, synapses, axons, and dendrites—offers an intriguing, potentially disruptive solution to society's ever-growing computational needs. Although much progress has been made in designing circuit elements that mimic the behavior of neurons and synapses, challenges remain in designing…
Pt-based alloy catalysts may promise considerable mass activity (MA) for oxygen reduction but are generally unsustainable over long-term cycles, particularly in practical proton exchange membrane fuel cells (PEMFCs). Herein, we report a series of Pt-based intermetallic compounds (Pt3Co, PtCo, and Pt3Ti) enclosed by ultrathin Pt skin with an average particle…
The control of messenger RNA (mRNA) translation has been increasingly recognized as a key regulatory step for gene control, but clear examples in eukaryotes are still scarce. Nucleo-cytoplasmic male sterilities (CMS) represent ideal genetic models to dissect genetic interactions between the mitochondria and the nucleus in plants. This trait is…
Anti–PD-1 therapies can activate tumor-specific T cells to destroy tumors. However, whether and how T cells with different antigen specificity and affinity are differentially regulated by PD-1 remain vaguely understood. Upon antigen stimulation, a variety of genes is induced in T cells. Recently, we found that T cell receptor (TCR)…
Thanks to the rapid progress in membrane protein crystallography and cryogenic electron microscopy in recent years, we have become increasingly accustomed to seeing protein structures characterized by long transmembrane α-helices (TMHs) crisscrossing a lipid bilayer (1). But how is it decided which segments of the polypeptide form the TMHs, and…
The Band Gap Problem Perhaps the most important property of a material is its fundamental band gap. This is the energy difference between adding and subtracting one electron from a system.

A study on the overlap between various psychiatric conditions found an alarmingly strong correlation between Attention-Deficit/Hyperactivity Disorder (ADHD) and substance use disorders in young adults, suggesting that one condition may hypothetically put people at risk of the other. Just about half of the young adults with ADHD who responded to a mental health survey also reported having had a su
Alzheimer's disease (AD) is the most common neurodegenerative disease in the world. Neuronal calcium dysfunction and microglial-mediated neuroinflammation are closely associated with the development of AD. However, it remains unknown whether calcium dysfunction contributes to microglial activation and, in turn, AD pathology in vivo. In this study, we demonstrated that the expression of calcium ho
The 2019 novel coronavirus pandemic (COVID-19) negatively affected global public health and socioeconomic development. Lockdowns and travel restrictions to contain COVID-19 resulted in reduced human activity and decreased anthropogenic emissions. However, the secondary effects of these restrictions on the biophysical environment are uncertain. Using remotely sensed big data, we investigated how l
Plasmonic lasers attracted interest for their ability to generate coherent light in mode volume smaller than the diffraction limit of photonic lasers. While nanoscale devices in one or two dimensions were demonstrated, it has been difficult to achieve plasmonic lasing with submicrometer cavities in all three dimensions. Here, we demonstrate submicrometer-sized, plasmonic lasers using cesium-lead-
Hepatocellular carcinomas (HCCs) are characterized by frequent somatic genomic copy number alterations (CNAs), with most of them biologically unexplored. Here, we performed integrative analyses combining CNAs with the transcriptomic data to reveal the cis- and trans-effects of CNAs in HCC. We identified recurrent genomic gains of chromosome 8q, which exhibit strong trans-effects and are broadly a
During navigation, animals often use recognition of familiar environmental contexts to guide motor action selection. The retrosplenial cortex (RSC) receives inputs from both visual cortex and subcortical regions required for spatial memory and projects to motor planning regions. However, it is not known whether RSC is important for associating familiar environmental contexts with specific motor a
A hydrogel scaffold for direct tissue-engineering application in water-irrigated, arthroscopic cartilage repair, is badly needed. However, such hydrogels must cure quickly under water, bind strongly and permanently to the surrounding tissue, and maintain sufficient mechanical strength to withstand the hydraulic pressure of arthroscopic irrigation (~10 kilopascal). To address these challenges, we
Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia is an autosomal dominant neurodegenerative disease caused by mutations in colony-stimulating factor 1 receptor (CSF1R). We sought to identify the role of microglial CSF1R haploinsufficiency in mediating pathogenesis. Using an inducible Cx3cr1 CreERT2/+ – Csf1r +/fl system, we found that postdevelopmental, microglia-specific
Quasicrystals are aperiodically ordered structures with unconventional rotational symmetry. Their peculiar features have been explored in photonics to engineer bandgaps for light waves. Magnons (spin waves) are collective spin excitations in magnetically ordered materials enabling non–charge-based information transmission in nanoscale devices. Here, we report on a two-dimensional magnonic quasicr
The remains of those who perished at Herculaneum in 79 CE offer a unique opportunity to examine lifeways across an ancient community who lived and died together.

Changes in metabolism that affect mitochondrial and glycolytic networks are hallmarks of cancer, but their impact in disease is still elusive. Using global proteomics and ubiquitome screens, we now show that Parkin, an E3 ubiquitin ligase and key effector of mitophagy altered in Parkinson's disease, shuts off mitochondrial dynamics and inhibits the non-oxidative phase of the pentose phosphate pat
Recent paleo reconstructions suggest that increased carbon storage in the Southern Ocean during glacial periods contributed to low glacial atmospheric carbon dioxide concentration ( p CO 2 ). However, quantifying its contribution in three-dimensional ocean general circulation models (OGCMs) has proven challenging. Here, we show that OGCM simulation with sedimentary process considering enhanced So
Resource polyphenisms, where single genotypes produce alternative feeding strategies in response to changing environments, are thought to be facilitators of evolutionary novelty. However, understanding the interplay between environment, morphology, and behavior and its significance is complex. We explore a radiation of Pristionchus nematodes with discrete polyphenic mouth forms and associated mic
Variability of North Tropical Atlantic (NTA) sea surface temperature (SST), characterized by a near-uniform warming at its positive phase, is a consequential mode of climate variability. Modulated by El Niño–Southern Oscillation (ENSO) and the North Atlantic Oscillation, NTA warm anomalies tend to induce La Niña events, droughts in Northeast Brazil, increased frequency of extreme hurricanes, and
The social soil-dwelling bacterium Myxococcus xanthus can form multicellular structures, known as fruiting bodies. Experiments in homogeneous environments have shown that this process is affected by the physicochemical properties of the substrate, but they have largely neglected the role of complex topographies. We experimentally demonstrate that the topography alters single-cell motility and mul
The SLC15 family of proton-coupled solute carriers PepT1 and PepT2 play a central role in human physiology as the principal route for acquiring and retaining dietary nitrogen. A remarkable feature of the SLC15 family is their extreme substrate promiscuity, which has enabled the targeting of these transporters for the improvement of oral bioavailability for several prodrug molecules. Although rece
The major obstacles for tumor vaccine to be surmounted are the lack of versatile property and immunity-inducing effectiveness. Induced pluripotent stem cells (iPSCs) expressed various antigens the same as multiple types of tumors, providing a promising source of wide-spectrum cancer vaccines.

Here the authors show how TRBV5 + T cell receptors are geared towards recognition of HLA-DQ8 bound hy
From Afghanistan to Myanmar, Nigeria to Azerbaijan, people caught in the midst of violence and instability will need to be vaccinated in order to fully end the pandemic. But hammering out the necessary interludes of peace isn't easy — in all of world history, a global ceasefire has never taken place.
Nature, Published online: 25 August 2021; doi:10.1038/d41586-021-02287-y Carbon dioxide reductions are key, but the IPCC's latest report highlights the benefits of making cuts to other greenhouse gases, too.
Carbon dioxide from the atmosphere can dissolve in oceans, lakes and ponds, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxide later, contributing to climate change. Now, researchers have developed tiny "nanojars," much smaller than the width of a human h
Ash rained down on Lake Tahoe on Tuesday and thick yellow smoke blotted out views of the mountains rimming its pristine blue waters as a massive wildfire threatened the alpine vacation spot on the California-Nevada state line.
The U.S. Department of Energy on Tuesday announced a new kind of climate observatory near the headwaters of the Colorado River that will help scientists better predict rain and snowfall in the U.S. West and determine how much of it will flow through the region.
Efter at det er lykkedes Region Nordjylland at nedbringe antallet af operationer for hoftebrud væsentligt, er målet nu også så vidt muligt at få has på de sidste. Det er til gengæld også det sværeste.
New research shows that keeping busy with a variety of activities can elicit both positive and negative emotions, and some of the relationship could depend on your age. A new study finds that engaging in diverse daily activities is associated with a diverse set of emotions.
PLUS. DTU-forskere har over fem år fulgt kapaciteten i elbiler, der bruges til regulering af elnettets frekvens, såkaldt Vehicle-to-Grid (V2G). Konklusionen er klar: Batteriets alder har større betydning, end hvor ofte det er blevet op- og afladet.
Nature, Published online: 25 August 2021; doi:10.1038/d41586-021-02318-8 The Australian Research Council's decision to reject early career funding applications that mention preprints is hopelessly outdated, say scientists.
Stingless bees are found throughout tropical and subtropical parts of the world and produce significantly less honey than their European honey bee counterparts (Apis mellifera) which are the world's major honey production species. However, stingless bee honey is highly prized as a specialty food, noted in Indigenous cultures for its medicinal properties, and attracts a high price. Now new research
Hydrogen produced from renewable energy sources with the help of electric power is deemed a key to the energy transition: It can be used to chemically store wind and solar energy in a CO2-neutral way. Researchers have studied water electrolysis processes on the surface of an iridium oxide catalyst.
Core samples taken from a stand of old growth Douglas-fir trees in the South Beach area just south of Newport showed reduced growth following the 9.0 earthquake and subsequent tsunami that struck the Pacific Northwest in 1700.
Scientists have taken a clear picture of electronic particles that make up a mysterious magnetic state called quantum spin liquid (QSL). The achievement could facilitate the development of superfast quantum computers and energy-efficient superconductors. The scientists are the first to capture an image of how electrons in a QSL decompose into spin-like particles called spinons and charge-like part
Emergency room patients who were flagged by an artificial-intelligence algorithm for possibly having sepsis received antibiotics sooner and had better outcomes, according to a study conducted by physician-researchers.
A new gene that controls the completion of meiosis in spermatogenesis has been discovered. Until now, details of the mechanism that inactivates the expression of genes involved in the meiotic program during spermatogenesis had not been clarified. The researchers believe that this may lead to an advancement in reproductive medicine, like identifying causes for infertility from azoospermia or sperma
Investing services aren't exactly cheap. So what's someone like you supposed to do when you want to invest your hard-earned money? Hiring a financial advisor can be pricey since most base their fees on how much of your money they're managing. This means their fees can range from 0.25-to-1 percent of what you're investing overall, which can add up pretty quickly. But what if you could manage your
Last spring, strings of bistro lights and outdoor seating in a courtyard behind the Student Center beckoned students to gather safely outside. The lights were a hit—and the plan is to make them permanent.
One of the things Rod Bayliss III '20, MEng '21, remembers most clearly from his childhood is his father's 1964 Ford Mustang. "I was fascinated by that car," says Bayliss. "Especially by the engine, this thing that converted oxygen and fuel into power." Bayliss grew up in Augusta, Georgia. Math and physics came easily to him, and in high school he developed a passion for Latin, Greek, and debatin
Reshmaan Hussam '09, PhD '15, once dreamed of becoming a "psychohistorian" like the protagonist in Isaac Asimov's Foundation novels who combines sociology, history, and statistics to save the world. Maybe, she thought, such a psychohistorian would be able to make sense of the stark and unnerving contrasts that marked her childhood living in suburban Virginia and visiting her parents' families in
As a boy, Eric Plosky '99, MCP '00, rode the New York subway with his grandmother to every city attraction on the map. "Whenever anyone asks me how I got into transportation, I always ask them, 'How did you get out of it?'" he says. "Every little kid seems to love trains and subways and buses and cars and planes, and for some reason they 'grow out of it.' I never did." Now, as chief of transporta
Abbie (Carlstein) Gregg '74 remembers giving up on wearing lab gloves during her undergraduate research at MIT. There weren't any small enough to fit her, at a time when undergraduate men outnumbered women on campus 15 to 1. Even so, it was the first time she'd met other women interested in engineering and technology—and she quickly found a home in the Metallurgy Department (now Materials Science
Linda (Getch) Dawson '71 grew up during the height of the space race between the US and the USSR. She recalls driving with her family to an observatory to hear the beeping of the Soviet satellite Sputnik as it passed overhead. "It's funny how your path takes different turns, but I always came back to that first love: aerospace," she says. Dawson's path took her from MIT to NASA, then into a secon
Continuing an annual tradition, Technology Day offered alumni an inside view of MIT's role in solving global challenges. The online symposium focused on online learning, cancer research, computing, and climate change.
