After one of the coldest winters in recent memory across much of the United States, new research is shedding light on a serious and often overlooked danger. Colder months are linked to significantly higher death rates from heart attacks, strokes, and coronary artery disease compared to milder periods. Findings presented…
Small cell lung cancer (SCLC) is among the most aggressive types of lung cancer, with a five-year survival rate of just five percent. Although it often responds well to chemotherapy at first, that success is usually short lived. Most patients experience a relapse, followed by rapid disease progression. Because of…
Scientists have identified 24 previously unknown deep-sea amphipod species — including one entirely new superfamily — in the Clarion-Clipperton Zone (CCZ) in the central Pacific Ocean. The findings, published March 24 in an open-access ZooKeys special issue, represent a major step forward in documenting life in the CCZ. This vast…
As bees and hummingbirds move from one flower to another, feeding on nectar while helping plants reproduce, they are also consuming something unexpected: small amounts of alcohol. In the first large survey of alcohol in floral nectar, biologists at the University of California, Berkeley detected ethanol in at least one…
For over 60 years, metformin has been a first-line treatment for type 2 diabetes, yet scientists have not fully understood how it works. Researchers at Baylor College of Medicine, along with international collaborators, have now identified an unexpected factor behind the drug’s effects: the brain. By uncovering a brain-based pathway…
The star γ Cas, visible to the naked eye in the constellation Cassiopeia, has confused astronomers for decades. It produces X-rays far more intense and hotter than what scientists expect from a typical massive star. New observations using the Resolve instrument aboard Japan’s XRISM space telescope now link these emissions…
Astronomers searching for extraterrestrial life have now identified the most promising places to look. Out of more than 6,000 known exoplanets, researchers have narrowed the list to just under 50 rocky worlds that may be capable of supporting life. The findings, published in Monthly Notices of the Royal Astronomical Society,…

March is National Colorectal Cancer Awareness Month, and a new poll from the Physicians Committee for Responsible Medicine and Morning Consult highlights a major knowledge gap. Nearly half of Americans do not realize that eating processed meat is linked to a higher risk of colorectal cancer. The survey, conducted among…
Lena Ting of Emory University and her team set out to understand how aging and Parkinson’s disease affect the way the brain and muscles respond when a person tries to regain balance. In earlier experiments, the researchers studied young adults by suddenly destabilizing them, essentially pulling a rug out from…
Scientists filmed atoms “roaming” before exploding — revealing a hidden driver of radiation damage. The process: The research centers on electron-transfer-mediated decay (ETMD), a radiation-driven process that can cause loosely bound atoms to break apart. This mechanism is especially important because it can generate highly reactive particles in water, making…
“Dance like nobody’s watching?” That idea does not apply to honey bees. Scientists have spent years decoding the honey bee “waggle dance,” a highly sophisticated form of communication. Researchers from the University of California San Diego and their international partners have now clarified how this behavior allows bees to share…
Fathers in Sweden are less likely to receive a psychiatric diagnosis during their partner’s pregnancy and in the months right after their child is born. But this pattern reverses over time. A new study published in JAMA Network Open reports that diagnoses of depression and stress-related conditions rise about a…
Researchers at Cornell University, working with collaborators, have created an extremely small neural implant that can sit on a grain of salt. Despite its size, the device can wirelessly transmit brain activity data from a living animal for more than a year. The advance, reported in Nature Electronics, shows that…
For memories to be useful, the brain must connect what happened with the situation in which it occurred. Researchers at the University of Bonn have now uncovered how the human brain handles this task. Their findings show that two distinct groups of neurons store content and context separately, then coordinate…
Metabolic-associated fatty liver disease (MASLD) impacts roughly 30% of people globally and has long lacked effective, targeted therapies. Now, researchers have uncovered a key genetic factor that worsens the condition. Even more surprising, the most effective way to target this factor may be an already approved and widely available treatment:…
Recent advances in supercomputing have allowed scientists to tackle a long-standing question in astronomy. Researchers have been trying to understand why the chemical makeup at the surface of red giant stars changes as these stars evolve. For many years, scientists struggled to connect what happens deep inside a red giant…
Researchers from the Canadian Museum of Nature have identified a previously unknown species of extinct rhinoceros from the High Arctic. The remarkably well-preserved fossil skeleton was uncovered in ancient lakebed sediments at Haughton Crater on Devon Island in Nunavut. This find represents the northernmost rhino species ever documented. Rhinoceroses have…
Researchers from the University of Oslo (UiO), Akershus University Hospital (Ahus), and international collaborators have published a new expert review in Nature Aging. The paper brings together more than 25 scientists, including clinicians and leading experts in aging biology and metabolism, with a strong focus on nicotinamide adenine dinucleotide (NAD+).…
For more than 100 years, scientists have pursued the idea of insulin in pill form, often described as a “dream” treatment for diabetes. The challenge has been the body itself. Enzymes in the digestive system break down insulin before it can work, and the intestine lacks a natural way to…
As quantum computers grow more powerful, many current encryption methods could eventually become vulnerable. One promising solution is quantum cryptography, which relies on the laws of physics rather than mathematical complexity to keep data secure. However, making quantum communication practical requires small, dependable devices that can accurately read delicate quantum…
Atomically thin semiconductors like tungsten disulfide (WS2) are emerging as key materials for next-generation photonic technologies. Even though they are only a single layer of atoms, they can host tightly bound excitons, which are electron and hole pairs that interact strongly with light. These materials can also produce new colors…
Researchers at Tokyo Metropolitan University have uncovered the real reason liquid drains from foams, resolving a long-standing scientific puzzle. Traditional physics models have consistently overestimated how tall a foam must be before liquid begins to leak out. By closely observing foam behavior, the team found that the key factor is…
University of Georgia researchers have identified and formally described two previously unrecognized species of black bass, known as Bartram’s bass and Altamaha bass, in a recently published study. Although the species are only now being officially classified, they have been seen before. Ecologist Bud Freeman first came across Micropterus pucpuggy,…
Researchers from the University of St Andrews have documented sperm whales striking each other with their heads, capturing the behavior on video and formally describing it for the first time. The finding supports stories from 19th-century sailors who reported whales using their heads to ram and push objects, sometimes even…
A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian has achieved a first by using galactic archaeology to uncover the past of a galaxy beyond the Milky Way. This method examines detailed chemical signatures in space to reveal how galaxies form and evolve over time.…
Low back pain (LBP) is one of the most widespread health issues globally, affecting people across all age groups and putting significant strain on healthcare systems. For many, the pain becomes long-lasting, disrupting work, sleep, and everyday life. In most cases, however, doctors cannot pinpoint a clear structural cause, which…
A Mayo Clinic-led study reports that postmenopausal women using menopausal hormone therapy experienced significantly greater weight loss when taking tirzepatide, a Food and Drug Administration-approved medication for overweight and obesity. On average, these women lost about 35% more weight compared to those using tirzepatide alone. The results, published in The…
Teeth can lose their brightness over time, even with consistent brushing. Staining can come from genetics or from everyday foods and drinks like coffee and tomatoes. While chemical whitening products are widely used, they can sometimes harm tooth enamel. To address this, researchers reporting in ACS Nano have created an…
A team led by neurobiologist Prof. Dr. Hilmar Bading at Heidelberg University has identified a key molecular process that drives the progression of Alzheimer’s disease.
