Black Americans experienced the highest per capita excess death rates, while regional surges contributed to higher excess death rates from COVID-19 and other causes, a new study finds.
Climate change poses new challenges to coffee production in Colombia, as it does to agricultural production anywhere in the world, but a new study shows effects vary widely depending on where the coffee beans grow.
One day, humankind may step foot on another habitable planet. That planet may look very different from Earth, but one thing will feel familiar—the rain.
The team of scientists and engineers behind NASA's Curiosity rover named a hill along the rover's path on Mars in honor of a recently deceased mission scientist. A craggy hump that stretches 450 feet (120 meters) tall, "Rafael Navarro mountain" is located on Mount Sharp in northwest Gale Crater.
In a new study, researchers found nearly half of those who share explicit images of others without permission feel remorse after the fact and 24% try to deflect blame onto victims. Amy Hasinoff, a researcher at the University of Colorado Denver, joined Danish researcher Sidsel K. Harder, to take a deeper dive into the issue of sexual abuse and image sharing.
A new study by Stanford University biologists finds an explanation for the idea that physical characteristics such as skin pigmentation are "only skin deep." Using genetic modeling, the team has found that when two populations with distinct traits combine over generations, traits of individuals within the resulting "admixed" population come to reveal very little about individuals' ancestry. Their...
If your day started with a cup of coffee, there's a good chance your morning brew came from Colombia. Home to some of the finest Arabica beans, the country is the world's third largest coffee producer. Climate change poses new challenges to coffee production in Colombia, as it does to agricultural production anywhere in the world, but a new University of Illinois study shows effects vary widely...
Shortly after President Biden was inaugurated, the man who was being given command of his coronavirus response had a message about what America needed to do. “We’re 43rd in the world in genomic sequencing,” said Jeff Zients at a press conference in January. “Totally unacceptable.” The answer, he suggested, was to “do the appropriate amount…
A team of polymer science and engineering researchers has demonstrated for the first time that the positions of tiny, flat, solid objects integrated in nanometrically thin membranes - resembling those of biological cells - can be controlled by mechanically varying the elastic forces in the membrane itself. This research milestone is a significant step toward the goal of creating ultrathin flexible...
A team of polymer science and engineering researchers at the University of Massachusetts Amherst has demonstrated for the first time that the positions of tiny, flat, solid objects integrated in nanometrically thin membranes—resembling those of biological cells—can be controlled by mechanically varying the elastic forces in the membrane itself. This research milestone is a significant step...
A team led by a biomedical scientist at the University of California, Riverside, has developed a new RNA-sequencing method— "Panoramic RNA Display by Overcoming RNA Modification Aborted Sequencing," or PANDORA-seq—that can help discover numerous modified small RNAs that were previously undetectable.
High levels of biodiversity in aquatic settings offers a wide range of vitamins, minerals, and fatty acids crucial for human health, a range of nutrients that are lacking in ecosystems where the number of species have been reduced by overfishing, pollution, or climate change, researchers report April 5 in the journal Proceedings of the National Academy of Sciences.
Overfishing likely did not cause the Atlantic cod, an iconic species, to evolve genetically and mature earlier, according to a study led by Rutgers University and the University of Oslo—the first of its kind—with major implications for ocean conservation.
SARS-CoV-2 showed the world with devastating clarity the threat undetected viruses can pose to global public health. SpillOver, a new web application developed by scientists at the University of California, Davis, and contributed to by experts from all over the world, ranks the risk of wildlife-to-human spillover for newly-discovered viruses.
A growing body of evidence suggests that biodiversity loss increases our exposure to both new and established zoonotic pathogens. Restoring and protecting nature is essential to preventing future pandemics. So reports a new Proceedings of the National Academy of Sciences (PNAS) paper that synthesizes current understanding about how biodiversity affects human health and provides recommendations for...
Nine of the hottest years in human history have occurred in the last decade. Without a major shift in this climate trajectory, the future of life on Earth is in question. Should humans, whose fossil-fueled society is driving climate change, use technology to put the brakes on global warming?
How do we become a complex, integrated multicellular organism from a single cell?
Researchers have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. Now, they have shown that a new technique incorporating aluminum results in rechargeable batteries that offer up to 10,000 error-free cycles.
Biomedical scientists have developed a new RNA-sequencing method -- 'Panoramic RNA Display by Overcoming RNA Modification Aborted Sequencing,' or PANDORA-seq -- that can help discover numerous modified small RNAs that were previously undetectable.
Head-mounted device on free-moving mice reveals how regions of the brain interact.
Researchers have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential atomic communications system that could be smaller and work better in noisy environments than conventional technology.
In an effort to save her beloved animals, Kathy Janson, a Maine Coon cat enthusiast reached out to a University of Cincinnati researcher to find a way to help her pets who were developing heart troubles.
Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential atomic communications system that could be smaller and work better in noisy environments than conventional technology.
