The Centers for Disease Control and Prevention's efforts to control drug-resistant bacteria finds that the percentage of bacteria carrying this resistance is declining. But it wants more data.

Researchers looked at states with medical marijuana dispensaries and those that allow home cultivation. They found lower use of opioids, when compared with states where marijuana remains illegal.

Scientists are trying to develop drugs to counteract an "undruggable" genetic variant that's responsible for about 30 percent of all cancer cases. It's high risk — high reward research.

How low should blood sugar go? A major medical society recommends less aggressive treatment for Type 2 diabetes. This controversial position goes against advice from numerous other groups.

The flu epidemic has peaked, the CDC said Friday. Activity declined last week, but the disease is still widespread and dangerous. And it's still not too late to get a flu shot.

A bedside computer loaded with software that tracks vital signs in the ICU can pick up early warning patterns, specialists say. But it takes a human care provider to sort the signal from the noise.

A 51-year-old man nearly died from septic shock, when a crushing injury led to overwhelming infection. After getting an experimental treatment, he's recovering well, but some doctors want more proof.

This blood test detected signs of cancer in 70 percent of people with eight common forms of the disease. But it was much less good at identifying cancer in people in the early stages.

The White House physician made public comments on Tuesday about President Trump's checkup at the Walter Reed Military Medical Center. Last week, the doctor said the president is in "excellent health."

Sequencing the DNA of cancer tumors to help pinpoint treatment is an emerging element of precision medicine. While patients and doctors alike want these tests, they often don't benefit patients.

If a female researcher asks a man if he's in pain, he's less likely to admit it. The effect of gender on study results has been known for years. But it's rarely disclosed or discussed.

In that game, a small Pennsylvania college, backed by a black quarterback, battled the University of California, Berkeley to the only tie in the history of the game.

The goal is to customize treatments for cancer and other diseases to a patient's own biology. But something as simple as failing to take care of tissue samples en route to the lab can derail that.

Hundreds of millions of dollars are pouring into research labs in an effort to collect genetic information on a million people. But some skeptics say the focus should be on humans themselves, not DNA.

Bacteria engineered with an expanded genetic alphabet can produce novel proteins, which could lead to the development of new drugs.

New guidelines have lowered the threshold for high blood pressure to 130/80, which makes it even more important to get an accurate reading. Here's how to increase the odds of getting it right.

An inherited disease called epidermolysis bullosa destroyed the 7-year-old's skin. Scientists grew new skin in the lab without the genetic flaw, and replaced 80 percent of his skin. He is thriving.

Industry says it costs about $2.7 billion to bring a cancer drug to market. But oncologists who ran the numbers put the average closer to $650 million. Drugs are priced way too high, the doctors say.

Even after a Harvard team took into account differences in age and weight among ancient specimens and knees today, they found that modern humans tend to have more osteoarthritis.

Scientists are trying to develop a vaccine to block the euphoria of heroin without interfering with other pain relief. The Trump administration hopes the approach might help with the opioid epidemic.
