For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a gigantic, flat sheet of matter surrounded by huge empty voids. This hidden structure—dominated by dark matter—balances gravitational forces and lets neighboring galaxies drift outward. The discovery finall
Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 femtoseconds, researchers at the University of Cambridge observed electrons blasting across a boundary in a single burst, far faster than long-standing theories predicted. Instead of slow, random movement,
Researchers created an AI-driven liquid biopsy that scans patterns in fragments of DNA circulating in the blood. The system detected early liver fibrosis and cirrhosis—conditions that often go unnoticed until serious damage occurs. By analyzing genome-wide DNA fragmentation patterns rather than specific mutations, the approach captures hidden signals about a person’s overall health. Early detectio

Scientists have uncovered new genetic rules that determine whether the immune system’s “killer” T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed genetic atlas of CD8 T cell states, researchers identified key molecular switches that push these cells toward either resilience or exhaustion. Remarkably, disabling just two previously unknown genes r
A new study shows that as humpback whale populations recover from past whaling, older males are gaining a major advantage in reproduction. Early in the recovery, breeding groups were dominated by younger whales. But as more mature males returned, they increasingly fathered more calves than their younger rivals. Scientists say experience in singing and competing may help older males win the breedin
Researchers at Cornell University have developed a powerful imaging technique that reveals atomic scale defects inside computer chips for the first time. Using an advanced electron microscopy method, the team mapped the exact positions of atoms inside tiny transistor structures and uncovered small imperfections nicknamed “mouse bites.” These defects form during the complex manufacturing process an
A sweeping new ALMA image has peeled back the veil on the Milky Way’s core, exposing a dense network of cold gas filaments near the central black hole. Stretching across 650 light-years, the survey maps the hidden fuel for star formation in remarkable detail and reveals a surprisingly complex chemical brew. This extreme region hosts some of the galaxy’s most massive, short-lived stars. The finding

Growing neurons rely on chemical cues to find their targets, but new research shows that the brain’s physical properties help shape those signals. Scientists discovered that tissue stiffness can trigger the production of guidance molecules through a force-sensing protein called Piezo1. This protein not only detects mechanical forces but also helps maintain the structure of brain tissue. The discov

Ocean temperatures may be quietly protecting the world from a global drought catastrophe. By analyzing more than a century of climate data, researchers discovered that droughts rarely spread across the planet at the same time, affecting only about 1.8%–6.5% of global land simultaneously—far less than earlier estimates. The reason lies largely in shifting ocean patterns such as El Niño and La Niña,

Scientists have used a laser technique to analyze Charles Darwin’s original Galápagos specimens without opening their nearly 200-year-old jars. By shining light through the glass, the method reveals the chemical makeup of the preservation fluids inside. Researchers successfully identified the contents in most samples, offering new clues about historical preservation practices. The breakthrough cou
A sweeping new study of more than 2,000 insect species reveals a troubling reality: many insects may be far less capable of coping with rising temperatures than scientists once hoped. Researchers found that while some species living at higher altitudes can temporarily boost their heat tolerance, many insects in tropical lowlands—where biodiversity is highest—lack this flexibility. Because insects
Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite’s unusual cell division process, ensuring its genetic material is properly separated as it multiplies. When scientists switched off ARK1 in laboratory experimen
A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a signal in just 125 picoseconds, making it the fastest pyroelectric detector ever built. The breakthrough could power next-generation multispectral cameras used in medicine, agriculture, and space-based sensing.
A new experimental drug is showing remarkable promise for children with Dravet syndrome, a severe genetic form of epilepsy. In clinical trials, the treatment zorevunersen cut seizures by as much as 91% while also improving quality of life for many patients. The therapy works by boosting the function of a key gene involved in nerve cell signaling. Encouraging results have led researchers to launch
Popular weight-loss drugs such as Ozempic, Wegovy, and Mounjaro may do more than help people shed pounds. New research suggests these GLP-1 medications could also help protect the heart after a heart attack by restoring blood flow in tiny blood vessels that often remain blocked even after doctors reopen a major artery.
Daily aspirin does not reliably prevent bowel cancer in people at average risk, according to a major new review. Any potential protective effect may take more than a decade to appear — if it appears at all — and the evidence for that benefit is weak. In contrast, the risk of serious bleeding begins right away, even with low-dose aspirin. Experts warn that prevention decisions should be individuali

Stiff knees and aching hips may seem like an inevitable part of aging, but experts say we’re getting osteoarthritis all wrong. Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological pro

Choosing the right method for multimodal AI—systems that combine text, images, and more—has long been trial and error. Emory physicists created a unifying mathematical framework that shows many AI techniques rely on the same core idea: compress data while preserving what’s most predictive. Their “control knob” approach helps researchers design better algorithms, use less data, and avoid wasted com

A sweeping new study reveals that what’s on your plate may directly shape the pesticides circulating in your body. Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the

Northern wildfires may be more dangerous for the climate than they appear. Researchers found that fires in boreal forests can burn deep into peat soils, releasing ancient carbon stored for hundreds or thousands of years. These slow, smoldering fires often look small from space, causing climate models to underestimate their emissions.

In Yellowstone’s wild chess match between wolves and cougars, it turns out the real power play is theft. After tracking nearly a decade of GPS data and thousands of kill sites, researchers found that wolves often muscle in on cougar kills—sometimes even killing the cats—but cougars never return the favor. Instead of fighting back, cougars adapt. As elk numbers dropped, they shifted toward hunting
When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants — but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body’s natural healing process, offering a potentially game-changing alternative. Made of 97% water, this soft material can be laser-printed into intricate bone-like struct
Scientists have identified a crucial molecular switch that decides whether pancreatic cancer cells resist chemotherapy or respond to it. The key player, a gene called GATA6, keeps tumours in a more structured and treatable form—but it gets shut down by an overactive KRAS-driven pathway. When researchers blocked that pathway, GATA6 levels rebounded and cancer cells became more sensitive to chemo. T

For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest that intelligence doesn’t live in one “smart” region of the brain at all. Instead, it emerges from how efficiently and flexibly the brain’s many network

Earth’s vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there are about two nearly identical “cryptic” species hiding in plain sight—genetically distinct but visually almost impossible to tell apart. Thanks to advances in DNA sequencing, scientists are uncoveri
