Breakthrough cancer therapy stops tumor growth without harming healthy cells

8:18
Scientists have found a new way to stop cancer growth without damaging healthy cells. Researchers from the Francis Crick Institute and Vividion Therapeutics discovered a compound that blocks the signal telling cancer cells to grow and divide. The treatment worked in mice with lung and breast tumors and didn’t cause harmful side effects seen in earlier drugs. Now entering human trials, this breakt…

How cutting lipids could starve breast cancer

8:18
Researchers found that triple-negative breast cancer cells are “addicted” to lipids, a feature tied to obesity. By studying mice, they discovered that high lipid levels alone accelerate tumor growth. Lowering these fats slowed cancer progression, suggesting that lipid-lowering treatments could help. The findings also caution against high-fat diets such as keto for patients with obesity.

Even “diet” soda may be quietly damaging your liver, scientists warn

7:14
Both regular and “diet” soft drinks may be far worse for liver health than believed. A massive study of over 120,000 participants found that consuming more than one can a day of either sugar-sweetened or low/no-sugar beverages sharply increased the risk of metabolic-associated steatotic liver disease (MASLD) and even liver-related deaths. Surprisingly, “diet” drinks carried similar or higher risk…

Something mysterious is lighting up the Milky Way. Could it be dark matter?

6:08
Scientists at Johns Hopkins may be closing in on dark matter’s elusive trail, uncovering a mysterious gamma ray glow at the heart of our galaxy that could signal unseen matter colliding — or perhaps the frantic spin of dying stars. Using advanced simulations that account for the Milky Way’s ancient formation, researchers found a near-perfect match between theoretical and observed gamma ray maps, …

Einstein’s overlooked idea could explain how the Universe really began

5:04
Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and quantum mechanics may alone explain the structure of the cosmos. This elegant approach challenges traditional Big Bang interpretations and revives a century-old idea rooted in Einstein’s work.

Surgery beats Ozempic for long-term health, Cleveland Clinic finds

18:27
Weight-loss surgery dramatically outperformed GLP-1 medications in improving longevity and reducing heart, kidney, and eye complications for people with obesity and diabetes. Over 10 years, patients lost far more weight and required fewer medications. Experts say surgery continues to offer survival advantages even in the age of potent obesity drugs.

Stanford scientists grow thousands of mini human brains using common food additive

18:27
Stanford scientists have solved a long-standing challenge in growing brain organoids by using a simple food additive to keep them from sticking together. The breakthrough enables the production of thousands of identical mini-brains at once, making large-scale testing and research possible. This leap could revolutionize how we study brain development and screen drugs for side effects. The discover…

Scientists just debunked the calcium and dementia myth

18.října
A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. Scientists say these results should reassure those using calcium to prevent osteoporosis, though more research is needed across broader populations.

Scientists finally read the hidden DNA code that shapes disease

18.října
EMBL researchers created SDR-seq, a next-generation tool that decodes both DNA and RNA from the same cell. It finally opens access to non-coding regions, where most disease-associated genetic variants lie. By revealing how these variants affect gene activity, scientists can better understand complex diseases and develop improved diagnostic tools.

Scientists 3D-print materials that stop vibrations cold

18.října
A collaboration between the University of Michigan and AFRL has resulted in 3D-printed metamaterials that can block vibrations using complex geometries. Inspired by nature and theoretical physics, these “kagome tubes” demonstrate how geometry can yield properties that chemistry alone cannot achieve. While the innovation could reshape structural design, researchers still face challenges in balanci…

Can Ozempic help you cut back on alcohol? Researchers think so

18.října
Semaglutide, tirzepatide, and other GLP-1 drugs appear to slow alcohol absorption and blunt its intoxicating effects, according to new research. The study found participants on these medications felt less drunk despite consuming the same amount of alcohol. This could point to a safer, faster-acting way to help people reduce drinking—distinct from traditional treatments that target the brain direc…

This common liver supplement could boost cancer treatment success

17.října
Salk Institute scientists discovered that bile acids in the liver can weaken immune cell function, making immunotherapy less effective against liver cancer. They pinpointed specific bile acids that suppress T cells and found that supplementing with UDCA reversed the effect, controlling tumor growth in mice. Since UDCA is already used for liver disease, it could quickly translate into clinical tri…

Cheaper than lithium, just as powerful — Sodium batteries are finally catching up

17.října
Researchers discovered how to stabilize a high-performance sodium compound, giving sodium-based solid-state batteries the power and stability they’ve long lacked. The new material conducts ions far more efficiently and supports thicker, energy-dense cathodes. Because it relies on a proven technique, it’s also easier to scale up for real-world use. This could bring safer, cheaper, greener batterie…

MIT finds traces of a lost world deep within planet Earth

17.října
Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of “proto Earth” material that survived the planet’s violent formation. The study suggests the original building blocks of Earth remain hidden beneath its surface, offering a direct glimpse into our planet’s ancient origi…

Saturn's moon Titan just broke one of chemistry’s oldest rules

17.října
Scientists from NASA and Chalmers University have discovered that incompatible substances can mix on Titan’s icy surface, breaking the “like dissolves like” rule of chemistry. Under ultra-cold conditions, hydrogen cyanide can form stable crystals with methane and ethane. This surprising reaction could help explain Titan’s mysterious landscapes and offer clues to how life’s building blocks formed.
