The United States needs to address a shortage of research monkeys by expanding breeding programs while also developing alternatives to monkey testing, an expert panel said in a report released Thursday.

The National Academies of Sciences, Engine...

Brain cancers are notoriously difficult to treat because most chemotherapy drugs can't breach the blood-brain barrier, a microscopic layer of cells that protect the brain from toxins.

But researchers now say they can temporarily open that barrier and get more chemo to brain tumors, using an experimental ultrasound device.

The technology led to a four- to sixfold increase in chemo dr...

Could an electronic chest "tattoo"-- wireless, lightweight and razor-thin -- upend heart monitoring and lower the odds of heart disease for folks who are at high-risk?

Just possibly.

The clear patch in question is not quite 4 by 5 inches in size, weighs less than an ounce, and is powered by a battery no bigger than a penny and just like a temporary tattoo sticker, it's designed to ...

Could a one-hour procedure that involves zapping a part of the intestines mean no more insulin for millions of folks with type 2 diabetes?

Maybe, according to a small study scheduled for presentation next week at the Digestive Disease Week meeting in Chicago.

The new minimally invasive procedure used controlled electrical pulses to change the lining of the first part of the small i...

When exercise studies are led by men, female participants are often in short supply.

While this underrepresentation of female research subjects has been documented in everything from clinical trials to cell cultures, a new study links researchers' gender and women's participation.

"Our findings provide direct evidence of the link between gender of authors and gender of research part...

Researchers are reporting progress on the path to a "universal" flu vaccine -- one that would battle all strains of the virus and give the world a weapon against future flu pandemics.

In an early clinical trial, U.S. government scientists found that their experimental flu vaccine was able to coax recipients' immune systems to produce "cross-reactive" antibodies. That is, they made antibod...

An experimental blood test may be able to catch a dozen different types of cancer with a high degree of accuracy -- including some that are particularly tricky to detect, a preliminary study suggests.

Researchers found that the blood test was usually on the money in detecting "signals" from 12 cancers. Importantly, the test was highly accurate in picking up early-stage cancer -- which is ...

New research in mice shows promise for a potential therapy for pancreatic cancer, which can be aggressive and hard to treat.

Researchers from Houston Methodist tested a device that, while smaller than a grain of rice, could deliver immunotherapy directly into a pancreatic tum...

A new national Alzheimer's disease and dementia database could be a game changer for research on the memory-robbing condition that now affects more than 6 million Americans.

Planning has begun at the National Institute on Aging (NIA) to fund the data platform. A $300 million grant for the six-ye...

An experimental injectable drug appears effective in reducing bleeds in patients with hemophilia A and B, according to a pair of new clinical trials.

Two-thirds of people with treatment-resistant hemophilia who were treated with the drug fitusiran had no bleeds at all after nine months, versus just 5% of people treated with drugs that enhance clotting, according to a trial published onlin...

Lawyer, entrepreneur and avid athlete Mark Clements participated in the 2005 St. George Marathon in Utah, but ongoing stomach pains made finishing the event a struggle.

"He was having some stomach pain,"recalled his sister Stacie Lindsey. "My dad had had ulcers, and so he thought that he had ulcers."

After finishing the marathon, Clements, then 38, went straight in to see his doctor...

An injection that relieves low back pain by helping damaged spinal discs regenerate appears to have sustained benefits, new clinical trial data show.

Most patients who received an injection of VIA Disc received back pain relief that lasted at least three years, said lead researcher Dr. D...

Swedish scientists say they have grown electrodes in living tissue, paving the way for formation of fully integrated electronic circuits in living organisms.

The development, which blurs the lines between biology and technology, could one day lead to therapies for neurological disorders.

"For several decades, we have tried to create electronics that mimic biology. Now we let biology...
