Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they're the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer ...

A sweeping nationwide study has found that U.S. counties located closer to operating nuclear power plants have higher cancer death rates than those farther away. Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 ...

Training harder may do more than build muscle--it could transform your gut. Researchers found that intense workouts change the balance of bacteria and important compounds in athletes' digestive systems. When training loads dropped, diet quality ...

A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older ...

People whose sugar intake was restricted before birth and in early childhood had markedly lower rates of heart disease later in life. Compared to those never exposed to rationing, their risks of heart attack, stroke, heart failure, and cardiovascular ...

Scientists at Stanford Medicine have unveiled a bold new kind of "universal" vaccine that could one day protect against everything from COVID-19 and the flu to bacterial pneumonia and even common allergens. Instead of targeting a specific virus or .. ...

Babies born in the early 2000s were exposed in the womb to far more "forever chemicals" than researchers once realized, according to a new study. By using advanced chemical screening on umbilical cord blood, scientists detected 42 different PFAS ...

Scientists have created a blood test that can estimate when Alzheimer's symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup ...

A sweeping new scientific review suggests that pecans -- America's native nut -- may pack more heart power than many people realize. After analyzing over 20 years of research, scientists found consistent evidence that eating pecans can improve key .. ...

Chronic wounds often spiral out of control because oxygen can't reach the deepest layers of injured tissue. A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it's needed most, using a tiny battery-powered system. In ...
