Evidence over alarm. Research over anecdote.
Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of California, Davis, provide mathematical proof that instabilities inherent in the Einstein-Euler equations imply that the current model of the expanding universe is not viable.
Extreme heat is now considered the deadliest weather and climate-related hazard in Europe, causing more deaths than floods or storms.
Researchers at the University Medical Center Göttingen (UMG) and the Max Planck Institute (MPI) for Multidisciplinary Sciences have elucidated how the production of certain proteins and their insertion into the inner membrane of mitochondria are coordinated.
Insurance companies could use a new research-based tool to reduce "proxy discrimination" in the pricing models that shape premiums in the sector.
Kenny Heckle grew up in Orlando, just west of NASA’s Kennedy Space Center in Florida. An 80s child, he comes from a long line of union pipefitters and fabricators. Heckle recalls the day 42 years ago at KARS Park, which is a NASA Exchange–run recreation area for the agency’s workforce and their guests, when he […]
(MedPage Today) -- After a lifetime of sobriety struggles, Matthew Perry spent the last days of his life desperately seeking the ketamine that would ultimately cause his death. The 2.5-year investigation and prosecution that followed came to a...
(MedPage Today) -- A real-world study of chronic pancreatitis found GLP-1 agonists to be associated with less pain medication use and lower risks for pancreatic interventions, including major surgery. (Gastro Hep Advances) The FDA expanded the...
Env. HealthA chemical used in mosquito repellents may disorient bumblebees, stopping them from finding their way back to their nests, a recent study found. Researchers in Finland exposed 123 buff-tailed bumblebees (Bombus terrestris), one of the most abundant bumblebee species in Europe, to a standard consumer mosquito repellent containing prallethrin, a type of pyrethroid insecticide. One […]
May 28, 2026 After a 12-year career at NASA, U.S. Army Brig. Gen. Andrew R. Morgan has retired from the agency to continue his military service. Morgan spent 272 days in space aboard the International Space Station. NASA selected Morgan to join its 21st astronaut class in August 2013. He launched to the space station […]

Env. HealthEarlier this month, state-owned oil company Petroecuador announced a new project involving “hydraulic fracturing” in an oil block in the Ecuadorian Amazon. As a result, some observers spoke out against the environmental risks of high-volume shale “fracking,” in which water and chemicals are injected at high pressures into the tight bedrock to release trapped oil […]
One in six internet-using children from a survey of nearly 12,000 children in 12 countries across Asia and Africa are found to experience at least one form of technology-facilitated sexual exploitation and abuse, with many experiences undisclosed, according to research published in Nature. The findings may help to inform prevention and response efforts where coordinated action by policymakers, law enforcement, and technology companies is urgently needed to protect children.
From Australia's remote deserts to the surface of Mars, geological mapping underpins how we understand landscapes, natural resources, and the processes that shape our planet and others beyond it.
In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the gravitational energy of the weights into impulses that drive the pendulum, which then moves the clock's gears, which move its hands.
Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare class of earthquakes occurring far deeper beneath the continental crust than scientists once believed possible.
Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul Erdős in 1946.
Public HealthWe still have a lot of questions about Trump's MFN deals with pharma companies.
NASA’s X-59 quiet supersonic research aircraft flies above NASA’s Armstrong Flight Research Center in Edwards, California, on April 28, 2026, during testing focused on lower-speed and altitude flight conditions in support of NASA’s Quesst mission. The X-59 has completed initial test flights at high altitudes and near-supersonic speeds, opening the door for additional flights focused […]
As an expert on personality disorders, people often ask me about psychopathy. It seems everybody has had an ex, a boss, a neighbor or a relative who they suspect has traits of it. People are curious about how to recognize psychopathy, and whether it can explain certain harmful behavior. It's easy to see why. Psychopathic people are everywhere—from books and movies to newspaper articles and academic papers.
Some plants are not the sitting ducks they appear to be when they come under attack. If a hungry caterpillar starts to chomp on the succulent leaves of a common bean plant, a highly sophisticated defense system kicks into action. The plant sends out a chemical distress signal that summons predatory wasps to its aid. Now, a study published in the journal Science Advances reveals how the plant pulls off this trick.
(MedPage Today) -- Exposure to traffic-related gases was associated with increased chronic rhinosinusitis risk, a case-control study showed, supporting a role for pollutants beyond particulate matter. Each standard deviation increase in exposure...
Wild pigs are generally considered among the world's most problematic invasive mammals. But a major new study from Aarhus Universitet shows that the introduced animals may actually have beneficial effects in North American forests.
Curtin University researchers have discovered some agricultural soils can naturally suppress one of Australia's most damaging broadacre crop diseases. The research, published in the journal Applied Soil Ecology, found some soils can inhibit infection and survival of Sclerotinia sclerotiorum—the fungus responsible for Sclerotinia stem rot, a disease that causes significant yield losses in broadacre crops such as canola and pulses.
Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However, the metals used, such as ruthenium and iridium, are often rare and expensive, limiting the potential to build new technology.
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped the world upside down. Roughly a billion years ago, the planet began to advance and mature, with plant life developing about 700 million years ago, but still with the occasional wild climate parties to keep things interesting.
Australian teens are experiencing high rates of intimate partner violence, one in 10 are relying on the withdrawal method for contraception and many don't know how to access help for their sexual health, according to the country's largest study of adolescents' sexual health and relationships.
