During an abrupt global cold snap nearly 13,000 years ago, the Gulf Stream ocean current shifted farther north, temporarily disrupting eastern Canada's oceanic ecosystems, a process that could happen again as the climate changes, a new study by UCL researchers finds.
Most people have experienced a heat wave on land. But heat waves can strike in the ocean too. And as the planet continues to warm, marine heat waves are growing longer and deadlier, hurting the seafood supply that billions of people worldwide rely on for their food and livelihoods.
By integrating findings from 140 studies and nearly 66,000 individuals, researchers from the Biosocial team at the Max Planck Institute for Human Development in collaboration with Columbia University in New York have shown that lower socioeconomic status and exposure to discrimination are consistently associated with accelerated biological aging, measured in the epigenome.
Researchers at Princeton University have harnessed AI to understand how drugs affect the dynamics of vital structures within the cell, introducing a tool that can map the shape of these structures to functional outcomes and shed light on important markers of health.
In an advance that could one day lead to new treatments for neurodegenerative diseases, Meredith Jackrel, an associate professor of chemistry in Arts & Sciences at Washington University in St. Louis, and her team have developed a method to rapidly produce and screen a class of disaggregase enzymes that can break down the misfolded proteins associated with ALS and Parkinson's disease.
The phenomenon El Niño has arrived, the U.S. weather agency said Thursday, and scientists expect the pattern, synonymous with droughts, floods and soaring temperatures, will intensify through the end of the year, potentially to historic strength.
This week's notable citations: Astronomers believe collapsing stars could spawn mini universes. Chimpanzees do not like unfairness. And a single dose of psilocybin temporarily restored function in an 80-year-old with Alzheimer's disease.
It's an insect everybody loves to hate. Pesky mosquitoes will be out in swarms as the weather warms up across the U.S.—and their bites aren't just itchy. They can transmit pathogens that can cause diseases like West Nile virus, Zika virus and malaria, to name a few.
Using NASA's Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused on disentangling the nature of a peculiar X-ray flare emitted by the cluster about two decades ago.
Antimicrobial resistance (AMR) is considered one of the most urgent global public health threats, with experts predicting that AMR could cause 39 million deaths between 2025 and 2050. AMR is not a single problem, but instead involves many different genes, pathogens, hosts and environmental factors.
A new study challenges a long-standing assumption about how cyanobacteria survive environmental stress. The study, led by researchers at the Israel Oceanographic and Limnological Research (IOLR)—the Kinneret Limnological Institute (KLI), shows that survival under prolonged heat stress is not determined solely by the ability to protect photosynthesis. Instead, survival may depend on a remarkable shift in cellular energy balance, with dark respiration compensating when photosynthetic electron transport becomes impaired.
In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly misused to produce materials for nuclear weapons.
A new study has created a detailed map of the pituitary gland, often called the body's "master gland" because it controls important functions such as growth, stress and reproduction. Researchers from the Center for Craniofacial & Regenerative Biology combined data from many studies to build a single, clearer picture of how this gland works. They created the Consensus Pituitary Atlas, along with an easy-to-use website where scientists can explore the data and analyze their own.
Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms or bacteria living in your gut, and this self-organization becomes much more difficult. A team of University of Amsterdam (UvA) researchers has demonstrated that activity can fundamentally alter one of the most important phase transitions in soft matter physics.
Physicists led by the University of Iowa have documented in the finest detail to date how energy from the sun interacts with Earth's magnetic field, which could yield greater insight into solar effects on Earth that drive space weather.
