Indigenous people in the United States are at higher risk of fatal police violence in and around American Indian/Alaska Native (AIAN) reservations, according to the first comprehensive national study on the subject from researchers at Drexel University's Dornsife School of Public Health and the University of Washington. The study, using data on the 203 AIAN people killed by police from 2013 through 2024, is published in the Proceedings of the National Academy of Sciences. The authors hope this work will inform policy action to better protect these communities. [...]
By 2050, nearly 20% of the areas currently suitable for cocoa cultivation in Colombia could lose the climate conditions needed for production, particularly in the lowlands of the Caribbean region and the country's northeastern departments, according to a new scientific study. [...]
Observations of the Rimae Bode region on the moon reveal five distinct types of terrain and identify several potential landing sites for China's first crewed mission, according to research titled "Geology of Rimae Bode region as priority site candidate for China's first crewed lunar mission." The work is published in Nature Astronomy. [...]
They raid compost bins, outsmart latches and sometimes look gleeful doing it. A new study in Animal Behaviour suggests raccoons may not just be opportunistic—they may be genuinely curious. [...]
Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling from dust and rock. They're time capsules, preserving clues about what the early solar system was like, and, ultimately, what the building blocks of planets are. [...]
An international team of researchers has modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found that the modified yeast is less likely to cause infection than unmodified strains of the same organism. The associated research paper is published in the journal Communications Biology. [...]
Somewhere in the North Atlantic, more than a kilometer beneath its surface, a cold-water coral reef stretches across an unnamed seamount. Despite never appearing on a chart, this underwater forest has existed for centuries, growing a centimeter or two each year. [...]
Global levels of physical activity have not improved over the past two decades, despite widespread policy development and adoption, and large disparities persist across gender and socioeconomic groups. The findings from three papers published in Nature Medicine and Nature Health indicate that current efforts to promote participation in physical activity are insufficient and that coordinated action is needed to ensure that physical activity contributes to public health and wider societal goals, including climate resilience. [...]
The search for materials that can conduct electricity at room temperature without losing energy is one of the greatest and most consequential challenges of modern physics: loss-free power transmission, more efficient motors and generators, more powerful quantum computers, cheaper MRI devices. Hardly any other material discovery has the potential to change so many areas of technology and everyday life at the same time. [...]
Drug discovery is like molecular Tetris. Chemists snap atoms together, adjusting the pieces until everything fits, and suddenly, a molecule makes a promising new medicine. Normally, creating better molecules consumes huge amounts of time and money. In a new study appearing in Nature, researchers have used machine learning to build a smarter prediction system that could speed up the process at a fraction of the cost. [...]
Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into electrical signals, potentially enabling faster and more energy-efficient devices. In recent years, researchers have begun exploring an unexpected platform for this purpose: soft matter. [...]
After a heart attack, the heart struggles to recoup and maintain energy. One-third of patients develop heart failure as a result—a condition that impacts 6.8 million Americans and carries a high lifetime risk, with 1 in 4 adults in the U.S. expected to develop the condition during their lifetime. This makes finding lasting treatment a medical priority. [...]
Climate change is threatening modern life in ways we are still finding, from food security to the economy to everyday living. It has been labeled a "threat multiplier" for its potential to complicate geopolitical relationships. Our efforts to adapt as a global society face obstacles brought on by inequality. [...]
For years, a protein inside our cells has quietly powered billions of dollars' worth of cancer drugs. Now a team of researchers have discovered that this workhorse protein, called cereblon, in addition to its known functions, can also fine-tune which proteins live and which are sent to the cellular trash. [...]
AI has designed candidate drugs for antibiotic-resistant infections and genetic diseases. But efforts to incorporate AI into the design of lipid nanoparticles (LNPs), the revolutionary delivery vehicles behind mRNA therapies like the COVID-19 vaccines, have been much more limited. [...]
Deep-sea waters are warming due to heat waves and climate change, and it could spell trouble for the oceans' delicate chemical and biological balance. However, a study published in Proceedings of the National Academy of Sciences demonstrates that the microbe Nitrosopumilus maritimus may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these surprisingly adaptable iron-dependent ammonia-oxidizing archaea will play an important role in reshaping ocean-nutrient distribution in a changing climate. [...]
When Sandia scientists Ryan Davis and Nathan Bays set out to find a better way to absorb and degrade PFAS in water sources, they kept running into the same issue: Detecting the chemicals in samples took too long. So, they came up with their own solution. They've developed a faster, cheaper way to test for PFAS. The research is published in the journal ACS Omega. [...]
Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion—we're not going to be able to make Mars anything like Earth anytime soon. A new paper available in pre-print on arXiv from Slava Turyshev of NASA's Jet Propulsion Laboratory is a good explainer as to why. [...]
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. According to a new international study published in Plant Disease, the ancestors of modern tymoviruses likely emerged before the last Ice Age, reshaping scientists' understanding of the vast evolutionary history of plant disease. [...]
Scientists usually study the molecular machinery that controls gene expression from the perspective of a linear, two-dimensional genome—even though DNA and its bound proteins function in three dimensions (3D). To better understand how key components of this machinery, such as super-enhancers, regulate genes in this 3D reality, scientists at St. Jude Children's Research Hospital have developed a new algorithm called BOUQUET. [...]
Most plants allow fungal microorganisms to enter their root cells and provide them with carbohydrates in exchange for a better supply of nutrients and water. Only leguminous plants like peas, beans, and clover enter into an additional, mutually beneficial symbiosis with nitrogen-fixing soil bacteria. The alliance with so-called rhizobia enables them to supply themselves with the nitrogen they need for their growth from the air. [...]
Researchers from Germany, Japan and India, led by scientists from DESY and the Universities of Kiel and Hamburg, have found a way to collectively make molecules on a flat surface rotate by exposing them to light using ultrafast light pulses from DESY's free-electron laser FLASH and a high-harmonic generation source. However, making those molecules dance is not the ultimate goal: this result could have an impact on next-generation quantum and energy materials for electronics, data storage and energy conversion. [...]
Herring from different parts of the Baltic Sea belong to distinct populations genetically adapted to local differences in salinity and temperature. However, these populations can also mix with each other, according to a new study by researchers from Uppsala University, Stockholm University and the Swedish University of Agricultural Sciences. These results have important implications for the management of the Baltic herring. The study is published in the Proceedings of the National Academy of Sciences. [...]
In some parts of the deep ocean, it can look like it's snowing. This "marine snow" is the dust and detritus that organisms slough off as they die and decompose. Marine snow can fall several kilometers to the deepest parts of the ocean, where the particles are buried in the seafloor for millennia. [...]
There is growing interest in the scientific community and private sector in biological approaches to marine carbon dioxide removal—strategies designed to enhance the ocean's natural ability to absorb carbon from the atmosphere. However, a study led by Megan Sullivan, a postdoctoral researcher in the University of Rhode Island's Graduate School of Oceanography (GSO), suggests that some proposals may overlook an important factor. [...]
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. The new study suggests that one of these newly confirmed planets is in the habitable zone. [...]
Antarctic sea ice coverage has likely rebounded this year, coming closer to its annual summer average after four years of extreme lows, US scientists said Monday. [...]
Who among us hasn't put off doing something we know we need to do while scrolling through just a few more TikToks, Instagram reels or YouTube shorts? New research from the William Allen White School of Journalism & Mass Communications at the University of Kansas has found that college students with lower self-control, stronger habitual short-form video use and who tended to use them to escape and fulfill the need to belong were prone to procrastinating via such short clips. [...]
More than 40% of extant large freshwater animals (megafauna), including carp, salmonids, crocodilians, turtles, beavers, and hippopotamuses, have been deliberately introduced outside their natural range, often for economic gain. While these alien species can provide substantial benefits to certain groups in the introduced regions, they also pose profound and often underestimated risks to native biodiversity and local people, according to a new study published in One Earth, led by researchers at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences.
