The United States is not in the midst of a "culture war" over race and racism. The animating force of our current conflict is not our differing values, beliefs, moral codes, or practices. The American people aren't divided. The American people are being divided. Republican operatives have buried the actual definition of critical race theory: "a way of looking at law's role platforming, facilitati
Click here for a list of resources from the Suicide Prevention Resource Center. An alarming new study found that increased cannabis use seems to be linked — at least in some way — with an increased prevalence of suicidal thoughts and attempts among young adults. Interestingly, the correlation persisted even when the teens and young adults didn't experience — or at least didn't report — any major
The greatest threat to American democracy today is not a repeat of January 6, but the possibility of a stolen presidential election. Contemporary democracies that die meet their end at the ballot box , through measures that are nominally constitutional. The looming danger is not that the mob will return; it's that mainstream Republicans will "legally" overturn an election. In 2018, when we wrote
Nicole Lawson spent the beginning of the pandemic incredibly worried about her daughter, who has asthma. Five-year-old Scarlett's asthma attacks were already landing her in the ER or urgent care every few months. Now a scary new virus was spreading. Respiratory viruses are known triggers of asthma attacks, and doctors also feared at the time that asthma itself could lead to more severe coronaviru
Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research is presented at the Goldschmidt Geochemistry Conference.
Scientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggests that the number of these impacts may have been 10 times higher than previously thought. This translates into a barrage of collisions—similar in scale to that of the asteroid strike that wiped out the dinosaurs—on average every 15 million years between 2.5 and 3.5 billion years ago. Some of t

America is in the grips of an epistemic crisis—an assault on reality, a rising inability to distinguish fact from fiction, an effort to shut down free inquiry—that poses an existential threat to liberal democracy. Which is why Jonathan Rauch's new book, The Constitution of Knowledge: A Defense of Truth , is so timely and so essential. It helps us understand this moment better than anything else I
Later this month, Blue Origin CEO and Amazon founder Jeff Bezos will be getting on board his space company's New Shepard rocket to travel to an altitude of 62 miles (100 km). That altitude, also known as the Kármán line, is the internationally recognized edge of space. And Blue Origin is arming itself with that fact to lash out at its competitor Virgin Galactic.

Coral reefs are a favorite spot for scuba divers and are among the world's most diverse ecosystems. For example, the Hawaiian coral reefs, known as the 'rainforests of the sea', host over 7,000 species of marine animals, fishes, birds and plants. But coral reefs are facing serious threats, including a number of diseases that have been linked to human activity.
Researchers have long expected that new variants of the coronavirus would gradually get better at evading vaccines. The bigger question, though, is what risk, exactly, breakthrough infections actually pose. But lingering scientific uncertainties have so far left clear guidance elusive.
A trio of researchers from the University of Colorado Boulder, has found the secret to fireflies flashing in unison: interacting locally through an active network of visual connections. In their paper published in the journal Science Advances, Raphael Sarfati, Julie Hayes and Orit Peleg, describe their study of the glowing insects in the Great Smoky Mountains in Tennessee and North Carolina, and w
As you read this text, the millions of cells that make up your body are hard at work. Within every cell is a flurry of activity keeping you alive, mostly driven by machinery that is made up of proteins. Some of this protein machinery is so important to living things that it has remained unchanged over millions of years of evolution.
Killer Sub The Chinese military recently declassified a decades-old program to develop robotic, uncrewed submarines that can target and fire at targets without human input. The revelation that autonomous killer drones already exist is alarming enough, but most shocking about the secret program is its timeline. The robotic submarines were reportedly built back in the 1990s, the South China Morning
Toilet Generator A researcher at a university in South Korea has devised a toilet that turns human waste into power, Reuters reports . As a bonus incentive, each use rewards, uh, poopers with a small amount of digital currency that they can trade in for a coffee or a cup of noodles on campus. The toilet first pumps your excrement into an underground tank, which means it uses less water right off
To understand the connection between human activity and a type of tumorlike disease called growth anomalies (GAs) researchers have started using an emerging molecular profiling method to identify 18 small molecules that promise to help them better understand the series of molecular reactions that lead to the disease.
Parts of an Arctic region called the Last Ice Area are already showing a decline in summer sea ice, researchers report. In a rapidly changing Arctic, the area might serve as a refuge—a place that could continue to harbor ice-dependent species when conditions in nearby areas become inhospitable. The region is north of Greenland and the islands of the Canadian Arctic Archipelago. "Current thinking
Why do some Europeans discriminate against Muslim immigrants, and how can it be reduced?

The late Janet Malcolm, writing about the Gossip Girl novels for The New Yorker in 2008, delighted in the heartlessness of the teenage characters—their voyeuristic cruelty and the sharp satisfaction they take in the downfall of their peers. What the series understands, Malcolm wrote, is that "children are a pleasure-seeking species, and that adolescence is a delicious last gasp (the light is most
Optic neuropathies are leading causes of irreversible visual impairment and blindness, currently affecting more than 100 million people worldwide. Glaucoma is a group of optic neuropathies attributed to progressive degeneration of retinal ganglion cells (RGCs). We have previously demonstrated an increase in survival of RGCs by the activation of macrophages,…
Recent declines in adult HIV-1 incidence have followed the large-scale expansion of antiretroviral therapy and primary HIV prevention across high-burden communities of sub-Saharan Africa. Mathematical modeling suggests that HIV risk will decline disproportionately in younger adult age-groups as interventions scale, concentrating new HIV infections in those >age 25 over time….
Virus infection causes major rearrangements in the subcellular architecture of eukaryotes, but its impact in prokaryotic cells was much less characterized. Here, we show that infection of the bacterium Bacillus subtilis by bacteriophage SPP1 leads to a hijacking of host replication proteins to assemble hybrid viral–bacterial replisomes for SPP1 genome…
Cancer cells acquire metabolic reprogramming to satisfy their high biogenetic demands, but little is known about how metabolic remodeling enables cancer cells to survive stress associated with genomic instability. Here, we show that the mitochondrial methylenetetrahydrofolate dehydrogenase (MTHFD2) is transcriptionally suppressed by p53, and its up-regulation by p53 inactivation leads…
Although inflammation is critical for the clearance of pathogens, uncontrolled inflammation also contributes to the development of multiple diseases such as cancer and sepsis. Since NF-κB–mediated transactivation in the nucleus is pivotal downstream of various stimuli to induce inflammation, searching the nuclear-localized targets specifically regulating NF-κB activation will provide important…
The emerging field of regenerative cell therapy is still limited by the few cell types that can reliably be differentiated from pluripotent stem cells and by the immune hurdle of commercially scalable allogeneic cell therapeutics. Here, we show that gene-edited, immune-evasive cell grafts can survive and successfully treat diseases in…
Human populations have grown to such an extent that our species has become a dominant force on the planet, prompting geologists to begin applying the term Anthropocene to recognize the present moment. Many approaches seek to explain the past and future of human population growth, in the form of narratives…
The objects in Fig. 1 clearly have different real-world shapes. But do they also have any shared shape appearance from our point of view? A longstanding philosophical tradition is divided on this question (1). But whereas most of this tradition relies on introspection, we recently took an experimental approach: When…
Dynamin oligomerizes into helical filaments on tubular membrane templates and, through constriction, cleaves them in a GTPase-driven way. Structural observations of GTP-dependent cross-bridges between neighboring filament turns have led to the suggestion that dynamin operates as a molecular ratchet motor. However, the proof of such mechanism remains absent. Particularly, it…
Natural killer (NK) cells comprise one subset of the innate lymphoid cell (ILC) family. Despite reported antitumor functions of NK cells, their tangible contribution to tumor control in humans remains controversial. This is due to incomplete understanding of the NK cell states within the tumor microenvironment (TME). Here, we demonstrate…

COVID-19 has led to over 3.47 million deaths worldwide and continues to devastate primarily middle- and low-income countries. High-frequency testing has been proposed as a potential solution to prevent outbreaks. However, current tests are not sufficiently low-cost, rapid, or scalable to enable broad COVID-19 testing. Here, we describe LEAD (Low-cost…
The authors of a new UW-led study write that because law enforcement directly interacts with a large number of people, "policing may be a conspicuous yet not-well understood driver of population health."
Researchers used artificial intelligence to obtain a more objective understanding of cell growth and division without preconceived assumptions. Using a deep-learning neural network, they were able to more accurately model the complex processes that affect cell size over time. This work may lead to advances in microbiology and industrial production of microorganisms.
Recess quality, not just the amount of time spent away from the classroom, plays a major role in whether children experience the full physical, mental and social-emotional benefits of recess, a new study has found.
Scientists investigated the efficiency of splicing across different human cell types. The results were surprising in that the splicing process appears to be quite inefficient, leaving most intronic sequences untouched as the transcripts are being synthesized. The study also reports variable patterns between the different introns within a gene and across cell lines, and it further highlights the co
The world's largest study of global climate related mortality found deaths related to hot temperatures increased in all regions from 2000 to 2019, indicating that global warming due to climate change will make this mortality figure worse in the future. The international research team looked at mortality and temperature data across the world from 2000 to 2019, a period when global temperatures rose

A survey offered to transgender and nonbinary people across six continents and in thirteen languages shows that during the first months of the COVID-19 pandemic, many faced reduced access to gender-affirming resources, and this reduction was linked to poorer mental health. Brooke Jarrett of the Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, and colleagues present the finding
Researchers have identified potential new treatment targets for Alzheimer's disease, as well as existing drugs that have therapeutic potential against these targets. The potential targets are defective proteins that lead to the buildup of amyloid in the brain, contributing to the onset of problems with memory and thinking that are the hallmark of Alzheimer's. The 15 existing drugs the researchers
Whether you call them semis, tractor-trailers, or 18-wheelers, heavy-duty trucks keep the economy (literally) moving. And at least some of them might be ready to go electric. These workhorses have an outsize climate impact. Globally, heavy-duty vehicles, including trucks and buses, make up about 10% of all motor vehicles but produce around half of all carbon dioxide emissions and over 70% of part
Aluminum (Al) metal is highly reactive but has excellent corrosion resistance because of the formation of a self-healing passive oxide layer on the surface. Here, we report that this native aluminum oxide shell can also stabilize and strengthen porous Al when the ligament (strut) size is decreased to the submicron or nanometer scale. The nanoporous Al with native oxide shell, which is a nanoporou
The gut microbiota is a potential environmental factor that influences the development of multiple sclerosis (MS). We and others have demonstrated that patients with MS and healthy individuals have distinct gut microbiomes. However, the pathogenic relevance of these differences remains unclear. Previously, we showed that bacteria that metabolize isoflavones are less abundant in patients with MS,
Climate warming and elevated ozone (eO 3 ) are important climate change components that can affect plant growth and plant-microbe interactions. However, the resulting impact on soil carbon (C) dynamics, as well as the underlying mechanisms, remains unclear. Here, we show that warming, eO 3 , and their combination induce tradeoffs between roots and their symbiotic arbuscular mycorrhizal fungi (AMF
Jupiter's rapidly rotating, strong magnetic field provides a natural laboratory that is key to understanding the dynamics of high-energy plasmas. Spectacular auroral x-ray flares are diagnostic of the most energetic processes governing magnetospheres but seemingly unique to Jupiter. Since their discovery 40 years ago, the processes that produce Jupiter's x-ray flares have remained unknown. Here,
The complex tumbling motion of spinning nonspherical objects is a topic of enduring interest, both in popular culture and in advanced scientific research. Here, we report all-optical control of the spin, precession, and nutation of vaterite microparticles levitated by counterpropagating circularly polarized laser beams guided in chiral hollow-core fiber. The circularly polarized light causes the
The 87 Rb- 87 Sr radiochronometer provides key insights into the timing of volatile element depletion in planetary bodies, yet the unknown nucleosynthetic origin of Sr anomalies in Ca-Al–rich inclusions (CAIs, the oldest dated solar system solids) challenges the reliability of resulting chronological interpretations. To identify the nature of these Sr anomalies, we performed step-leaching experim
A warm slab thermal structure plays an important role in controlling seismic properties of the slab and mantle wedge. Among warm subduction zones, most notably in southwest Japan, the spatial distribution of large S -wave delay times and deep nonvolcanic tremors in the forearc mantle indicate the presence of a serpentinite layer along the slab interface. However, the conditions under which such a
Earth's climate system is complex and inherently nonlinear, which can induce some extraneous cycles in paleoclimatic proxies at orbital time scales. The paleoenvironmental consequences of these extraneous cycles are debated owing to their complex origin. Here, we compile high-resolution datasets of total organic carbon (TOC) and stable carbon isotope ( 13 C org ) datasets to investigate organic c
The role of ubiquitin carboxyl-terminal hydrolase L1 ( UCHL1 ; also called PARK5 ) in the pathogenesis of Parkinson's disease (PD) has been controversial. Here, we find that the loss of UCHL1 destabilizes pyruvate kinase (PKM) and mitigates the PD-related phenotypes induced by PTEN-induced kinase 1 ( PINK1 ) or Parkin loss-of-function mutations in Drosophila and mammalian cells. In UCHL1 knockout
Guard cells control the aperture of plant stomata, which are crucial for global fluxes of CO 2 and water. In turn, guard cell anion channels are seen as key players for stomatal closure, but is activation of these channels sufficient to limit plant water loss? To answer this open question, we used an optogenetic approach based on the light-gated anion channelrhodopsin 1 ( Gt ACR1). In tobacco gua
The response of endothelial cells to mechanical forces is a critical determinant of vascular health. Vascular pathologies, such as atherosclerosis, characterized by abnormal mechanical forces are frequently accompanied by endothelial-to-mesenchymal transition (EndMT). However, how forces affect the mechanotransduction pathways controlling cellular plasticity, inflammation, and, ultimately, vessel
A dipole wave is composed of head-to-tail connected electric dipoles in the form of sine function. Potential applications in information carrying, transporting, and processing are expected, and logic circuits based on nonlinear wave interaction are promising for dipole waves. Although similar spin waves are well known in ferromagnetic materials for their roles in some physical essence, electric d
The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six continents, and found that urban soils are important hotspots for soil bacterial, protist and functional gene diversity, but support highly homogenized microbial communities worldwid
Transfer printing is a technique that integrates heterogeneous materials by readily retrieving functional elements from a grown substrate and subsequently printing them onto a specific target site. These strategies are broadly exploited to construct heterogeneously integrated electronic devices. A typical wet transfer printing method exhibits limitations related to unwanted displacement and shape
Tumor cell intravasation preferentially occurs in regions of low fluid shear because high shear is detrimental to tumor cells. Here, we describe a molecular mechanism by which cells avoid high shear during intravasation. The transition from migration to intravasation was modeled using a microfluidic device where cells migrating inside longitudinal tissue-like microchannels encounter an orthogonal
The role of quantum fluctuations in the self-assembly of soft materials is relatively unexplored, which could be important in the development of next-generation quantum materials. Here, we report two species of nanometer-sized bubbles in liquid helium-4 that contain six and eight electrons, forming a versatile, platform to study self-assembly at the intersection of classical and quantum worlds. T
Two factors that play a key role in climate change—increased climate warming and elevated ozone levels—appear to have detrimental effects on soybean plant roots, their relationship with symbiotic microorganisms in the soil and the ways the plants sequester carbon.
Plants have microscopically small pores on the surface of their leaves called stomata. These help plants regulate the influx of carbon dioxide for photosynthesis. They also prevent the loss of too much water and withering away during drought.

It's hard to miss a flashlight beam pointed straight at you. But that beam viewed from the side appears significantly dimmer. The same holds true for some cosmic objects: Like a flashlight, they radiate primarily in one direction, and they look dramatically different depending on whether the beam points away from Earth (and nearby space telescopes) or straight at it.
Stressed out mice have damaged neurons in their brains, and magic mushrooms can help them grow back. Neuronal damage, specifically a lack of dendritic spines, also has been observed in cases of depression in humans. So far, the findings are limited to mice, but the results hold promise for humans. Psychedelics, long demonized as substances used only by quacks and hippies, have been enjoying a ren
Changing climate patterns have left millions of people vulnerable to weather extremes. As temperature fluctuations become more commonplace around the world, conventional power-guzzling cooling and heating systems need a more innovative, energy-efficient alternative, and in turn, lessen the burden on already struggling power grids.

Prior to the Covid-19 pandemic, the idea of working from home was unthinkable to a lot of people. Between time-wasting (and calorie-increasing) temptations like the fridge, couch, or TV, distractions from one's family or roommates, and the lack of office resources and camaraderie, home was a place for leisure, not labor. But with the trial-by-fire that was the last year and a half, we discovered
On average, Dutch breeding birds have become more numerous in the period 1980-2010. The common species have even done better than birds in other European countries. Farmland birds are an exception: they declined sharply both in the Netherlands and elsewhere in Europe.
Pichia pastoris (syn. Komagataella phaffii), a model methylotrophic yeast, can easily achieve high density fermentation, and thus is considered as a promising chassis cell for efficient methanol biotransformation. However, inefficient gene editing and a lack of synthetic biology tools hinder its metabolic engineering toward industrial application.
An unprecedented heat wave that started around June 26 smashed numerous all-time temperature records in the Pacific Northwest and western Canada. NASA's Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, captured the progression of this slow-moving heat dome across the region from June 21 to 30. An animation of some of the AIRS data show surface air temperature anomalies—values above
Although the giant panda is in practice a herbivore, its masticatory system functions differently from the other herbivores. Through the processes of natural selection, the giant panda's dietary preference has strongly impacted the evolution of its teeth and jaws. Researchers from the Institute of Dentistry at the University of Turku and the Biodiversity unit of the University of Turku together wi
Food insecurity is a major problem in the US, and it worsened during the COVID-19 pandemic. The Supplemental Nutrition Assistance Program (SNAP) provides some relief, but millions of Americans still lack adequate access to healthy food. A new study from the University of Illinois proposes a potential solution.
Certain metabolites of bacteria from the intestine make immune cells more aggressive as a new study conducted by scientists from german universities in Würzburg and Marburg reveals. The findings could help improve cancer therapies.
The major cause of Parkinson's Disease is a dysregulation of immune genes central for fighting against viruses, a new study reveals. Researchers from the University of Copenhagen show that this dysregulation leads to a malfunction in the cell's powerhouse, which cannot produce sufficient energy for neurons to stay alive, causing them to gradually die.
Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells. But when produced too abundantly, they damage DNA and render some cellular components dysfunctional. Now, an international res
It's summer, and summer means grilling, and grilling means arguing about grilling. Among the dads (and the dads at heart) crewing their outdoor firepits, fuel is a popular subject of debate. Gas grills, fired from natural-gas lines or propane tanks, offer convenience. But many outdoor-cooking purists insist that wood or charcoal is the only respectable way to sear—and the only way to barbecue. (I
A new study provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal's biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations.
Researchers at the Universitat Autonoma de Barcelona describe the mechanism through which a non-toxic derivative of the tetanus neurotoxin (Hc-TeTx) may serve to treat depression and neurodegenerative diseases, as has already been demonstrated in animal models.
A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or "qubits."
Marine scientists aboard Schmidt Ocean Institute's research vessel Falkor have identified likely new marine species and deep sea organisms on nine seamounts that were explored for the first time in the remote Phoenix Islands Archipelago. In a 34-day expedition that ended today, scientists also conducted high-resolution seafloor mapping of more than 30,000 square kilometers and video exploration of
Food waste is a huge problem for the environment. Making and getting rid of excess food accounts for around 8-10% of greenhouse gas emissions. In fact, if global food waste were a country, it would rank third in the world for greenhouse gas emissions after China and the US. Globally, we throw away around a third of all food we produce.
Down in the main lab of the R/V Marcus Langseth, you'll find an array of monitors—46, to be exact!—all displaying information about the data we're collecting. While many of the screens are dedicated to monitoring the seismic data and the instrumentation related to collecting the seismic data, there are two screens that display data related to the multibeam echo sounder. A multibeam echo sounder is
Warnings of another severe wildfire season abound, as do efforts to reduce the risk of ignition. Yet few people take precautions against wildfire smoke, experts say. On the heels of the worst wildfire season in California history, an extended megadrought is priming the state for more destructive blazes in 2021. Given the severity of last year's fires, many Bay Area communities are facing the immi
For livestock diseases, like foot-and-mouth disease (FMD) and swine flu, rapid culling and carcass disposal are well-established strategies for halting an outbreak and limiting its impact. However, even when infection is quickly detected delays in these interventions may permit pathogen transmission from infected farms.
Climatic changes are increasingly giving rise to major fires on peatlands in the northern hemisphere, which release massive quantities of carbon dioxide. However, the biomass of the peatland is not entirely consumed by fire, some turns to charcoal in the absence of air. Now, Dr. Tianran Sun and Professor Lars Angenent from Environmental Biotechnology at the University of Tübingen in cooperation wi
Seafarers of different faiths and no faith rely on support from port chaplains in coping with what is often dangerous work in challenging institutionalized workplace settings, research from Cardiff University has found.
"The best laid plans of mice and men often go awry"—this famous paraphrase of Scottish poet Robert Burns sometimes sums up human ingenuity. That is exactly what happened when a county in Washington State decided to replace all of its county-owned streetlights with LEDs, at least partially in an effort to combat light pollution. New research shows that they actually made the light pollution worse.
After carefully observing dim objects in the night sky, you don't want to waste any precious signal on its way from the telescope dish to the detector. But in the case of far-infrared astronomy, it's not as easy as it sounds to transport the signal efficiently. In fact, it's even an endeavor to measure the exact amount of signal that gets lost. Scientists from SRON and TU Delft have now found a ne
People contribute only very little to climate protection, because they underestimate the willingness of others to contribute. This is the central result of a new study by the behavioral economists Peter Andre, Teodora Boneva, Felix Chopra and Armin Falk, members of the Cluster of Excellence ECONtribute at the Universities of Bonn and Cologne, published as an ECONtribute Discussion Paper.
Planetary scientists estimate that each year, about 500 meteorites survive the fiery trip through Earth's atmosphere and fall to our planet's surface. Most are quite small, and less than 2% of them are ever recovered. While the majority of rocks from space may not be recoverable due to ending up in oceans or remote, inaccessible areas, other meteorite falls are just not witnessed or known about.
NMs have made their way into our lives and are helping to improve—even revolutionize—many industries. In the cosmetics industry, mineral nanoparticles help create sunscreens that provide improved protection from the sun's harmful rays. In sports, carbon nanotubes make for lighter and better baseball bats. Benefits for healthcare include more effective drug delivery to affected areas of the body. T

Drs. Nobuo Noda (Director) and Tatsuro Maruyama (Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that lipidated Atg8, the most famous factor that mediates autophagy, has membrane perturbation activity and elucidated that this activity is responsible for efficient autophagosome formation.
Deforestation in the Brazilian Amazon made global headlines in 2019, thanks to massive wildfires and the election of anti-environmentalist president Jair Bolsonaro. Brazilians took to the streets against it, and retailers and consumers threatened to boycott Brazilian products. But while the pandemic has dominated the headlines in 2020 and 2021, deforestation continues to rise.
The removal of ethane (C2H6) from its analogous ethylene (C2H4) is of great importance in the petrochemical industry, and is highly challenging due to their similar physicochemical properties. The use of emerging porous organic cage (POC) materials for C2H6/C2H4 separation is still in its infancy.

In spite of many clinical options, people with mental health problems including eating disorders often do not access professional help within the crucial first 12 months – in part because of lack of information in the community about accessing targeted services. Anxiety and depression are normal reactions to situations such as pandemic lockdowns but arming yourself with some useful strategies can
How a pandemic progresses in a country is largely determined by social, political and psychological processes. Predicting these socio-dynamics seems hardly possible until today; thus making it impossible to foresee the course the pandemic takes. This is where a new simulation study carried out by the Helmholtz-Zentrum Hereon comes into play, which is now published in the journal Scientific Reports
According to ARRS' American Journal of Roentgenology, among the 78 patients with cancer who underwent standard-dose chest CT and reduced-dose chest CT in the same imaging encounter, the reduced-dose protocol detected greater than 90% of lung nodules identified on the standard-dose examination.
The shale boom (mining of shale oil and gas) has contributed to an increase of crime rates in US states where 50-60% of the population lives in rural areas. The rate of violent crime has increased by about 36%. Because of this, each state had to spend $ 15.67 million additional victimization costs per year.
Researchers from Tokyo Medical and Dental University (TMDU) have identified important parts of the pathway by which a high-fat diet affects the body's immune response, leading eventually to atherosclerosis. Working with mouse models, they clarified how histone H3 citrullination activates neutrophils with serum CXCL1 elevation. Identifying these steps could lead to new diagnostic tools and treatmen
A researcher from the University of Tsukuba has introduced a new theory for superconductivity that can better explain the results of recent experiments with high-temperature superconductors. By focusing on the "Berry connection," this work may lead to energy distribution with much less electrical resistance.

However, for southern-based researchers and travelers, returning to northern, Indigenous communities either for leisure or research fieldwork in summer 2
It has become a mantra of climate scientists that global warming is just what it says – global. It is a statistical average over time. It cannot be tied to any specific weather event, even if it predicts that statistically such events are more likely. However, the current heat wave in the North American Northwest is so statistically extreme, that climate scientists are discussing it in very diffe
Microsoft took the wraps off Windows 11 recently, and we expect the new OS to arrive later this year.
