Researchers at the University of Houston have developed a new safety system that can help drones avoid crashes while they are flying. The technology constantly watches the drone’s movement and can step in immediately if it detects that the drone is heading toward danger. The new system was created by Marzia Cescon, an assistant professor of Mechanical and Aerospace Engineering at the University of Houston’s Cullen College of Engineering.

Astronomers have taken a closer look at a giant planet called Beta Pictoris b, hoping to solve one of the biggest mysteries in planetary science: where did this massive world form? Although new observations have provided much better data, the planet is still refusing to reveal its true origins.

What do you do when a fireball lights up the sky and every camera meant to capture it comes up empty? Last spring, a bright meteor streaked across Alaska in broad daylight, and the usual tools scientists rely on, satellites and all sky cameras, failed to give a clear picture of what had happened.

Researchers at the University of Delaware have developed an environmentally friendly way to recycle one of the world’s rarest and most valuable metals from hydrogen energy devices. The new method can recover precious metals while also preserving key parts of the devices, helping reduce waste and support the growing clean energy industry. The research focuses on proton exchange membrane (PEM) electrolyzers and fuel cells.

Cancer is now one of the biggest health challenges facing the world. It affects people of every age, race, and country. Cancer is not a single disease but a group of more than 100 diseases that begin when abnormal cells grow out of control. These cells can spread to other parts of the body if they are not found and treated. Thanks to better treatments, many people now survive cancer, but millions of others still lose their lives every year.

A blood test performed only weeks after cancer surgery could help doctors decide who should receive chemotherapy and who may be able to avoid it, according to new research presented at the ESMO Gastrointestinal Cancers Congress 2026. Colorectal cancer affects the large intestine or rectum and is the third most common cancer worldwide. It often spreads to the liver, making treatment more difficult.

Could the bacteria living inside your intestines reveal whether you will develop type 2 diabetes years from now? According to a major Swedish study, the answer may be yes. Researchers from Chalmers University of Technology have found that certain gut bacteria and changes in metabolism appear long before diabetes is diagnosed. Their findings were published in Cell Reports Medicine. Type 2 diabetes often develops slowly over many years.

A large international study has found that hormone levels in people with common adrenal tumors are much less stable than doctors once believed. The research, published in The Lancet Diabetes & Endocrinology, shows that people whose cortisol levels stay high over many years are much more likely to develop worsening high blood pressure and other health problems linked to heart disease. The findings could change the way doctors monitor thousands of patients around the world.

Statins are among the most commonly prescribed medicines in the world. Doctors use them to lower cholesterol levels and reduce the risk of heart attacks, strokes, and other serious heart problems. For millions of people, these medicines have saved lives by helping keep blood vessels healthy and reducing the buildup of fatty plaques inside arteries. Even though statins are very effective, not everyone finds them easy to take.

Scientists have developed a promising new experimental treatment that could one day help men with one of the most dangerous forms of prostate cancer. The treatment is designed not only to slow the growth of tumors but also to stop cancer cells from spreading to other parts of the body. Researchers believe this double action could make it especially valuable for patients with aggressive disease, where current treatments often become less effective over time.
