Chinese researchers have successfully created chimeric embryos by combining human stem cells and monkey blastocysts, a groundbreaking advance with both practical and ethical implications for the future of medicine.
Brain temperature differs from body temperature and is an important indicator of health after an injury, but it's difficult to measure without invasive procedures such as the implantation of temperature probes. A group of researchers has proposed a new biophysical model that can predict personalized brain temperature using data from magnetic resonance imaging (MRI) of individual brain tissue and vessel structures.
The first four months of the COVID-19 pandemic saw large decreases in the mean and median rent prices in the largest metropolitan cities in the United States, but those decreases were driven almost entirely by price reductions in Black, Latino and diverse neighborhoods, according to new research on how the pandemic impacted rental markets.
A new study argues that just 2.8% of Earth's terrestrial area is "ecologically intact," about 10 times lower than previous estimates, which scientists use to help prioritize areas for conservation.
Physicists have concluded that some masses of boson particles — members of the things-that-could-explain-dark-matter club — don't actually exist, meaning the parameters for locating the presumably vast but hypothetical material just became more refined.
U.S. counties with lower per capita income and greater Republican orientation were associated with significantly reduced physical distancing during the COVID-19 pandemic, according to a new study that shows how government policies failed to close disparities between communities throughout almost the entirety of the pandemic.
The medical organizations that produce widely followed guidelines for the diagnosis and treatment of health conditions have largely failed to create adequate policies addressing conflicts of interest in how those guidelines are produced, an analysis found, creating a risk for biased medical advice.
A technique used worldwide to determine organic carbon pollution in natural waters has been revealed to overestimate concentration levels by up to 90%, meaning some environmental policies may be based on considerably incorrect data.
Scientists have used 3D cell printing to create a model of skin that mimics the skin ailments associated with diabetes, allowing researchers to study symptoms and therapeutics related to these conditions without relying on animal models.
Physicists and material scientists have created a way to interact with electricity-based "polar vortices" that respond to signals at a rate of nearly 400 billion times per second, a fundamental scientific approach that could someday provide data storage and processing that is more compact and more than 100 times faster than some modern central processing units.
Ocean acidification is a threat to shell-making organisms across the seas, but one species of oyster may provide a unique exception to this rule.
A reusable sensor built with tiny gold particles and a common sugar can identify a wide range of concentrations of the bacterium Escherichia coli at low cost, which could potentially protect millions of people from bacteria in food or sewage water.
Canadian biologists showed that neurons afflicted with Alzheimer's disease develop disruptive G-quadruplex structures in their DNA — and the researchers found a gene that prevents that.
School closures early in the COVID-19 pandemic cut the projected number of coronavirus infections in the San Francisco Bay Area in half, but schools can reopen safely if they follow a series of safety precautions, according to computer modeling work by University of California, Berkeley researchers.
Researchers find substantial evidence that, relative to their unexposed peers, school shooting survivors in the U.S. experience declines in health and well-being, engage in more risky behaviors and have worse education and labor market outcomes.
Scientists at the University of Zurich have discovered that humans can more efficiently process and categorize screams that evoke positive or nonalarming emotions than those that communicate aggression or fear.
Employees dealing with work-induced stress can experience changes to their physiology, according to organizational behavior researchers, which may result in their personality traits fluctuating or even fundamentally changing over time.
A hazardous waste site shaves up to 1.22 years off a neighboring community's life expectancy, a new study shows, with the worst effects occurring in poorer neighborhoods with more people of color.
Researchers have developed a vibrating platform that can reduce the effects of cybersickness for some virtual reality users, addressing an increasingly urgent problem as VR becomes more prevalent in education, art, entertainment and communications.
Researchers have found that even at doses too low to kill, agricultural chemicals impact the color preference, respiration and locomotion of native stingless bees in South and Central America.
Physicists may have discovered the first naturally occurring "bombs" lying dormant within white dwarf stars roaming outer space, and if detonated, the explosive material could force an entire star's destruction.
