Could a drug used to treat amyotrophic lateral sclerosis (ALS) help people with mild Alzheimer's disease?

The results of a small new study suggest the strategy could work.

Riluzole has been used for more than 20 years to slow the progression of ALS, commonly called Lou Gehrig's disease. This phase 2 study found that the drug slowed brain metabolic decline and had a positive effect o...

Dogs may be man's best friend, but cats may hold critical keys to humans' health.

Our feline friends have the potential to become a valuable model for genetic research, because their genome is similar to that of people, according to Leslie Lyons of the Feline Genetics Laboratory at the University of Missouri in Columbia.

"Using cats in research is really overlooked, since people don...

Trusting science is good, but it could put you at risk for being duped by false science, or "pseudoscience," if you let your guard down, researchers warn.

Investigators found that people who trust science are more likely to believe and share false claims that contain scientific references than those who don't trust science.

"We conclude that trust in science, although desirable in m...

While efforts to develop Alzheimer's medications have so far borne little fruit, new research highlights the therapeutic promise of two non-drug tools: light and sound.

According to a pair of small new studies, exposing Alzheimer's patients to an hour a day of carefully modulated light and/or sound appears, over time, to slow down the telltale brain degeneration that typifies disease prog...

Children with autism differ socially and developmentally from their typically developing peers. Now, researchers say there are also differences in their array of healthy gut bacteria or "microbiome."

The findings may lead to earlier treatment for kids with an autism spectrum disorder, suggested the authors of a new small study.

The gut microbiome can vary according to where people ...

Lisa, 51, has amyotrophic lateral sclerosis (ALS), a di...

An experimental COVID-19 vaccine could potentially provide universal protection against future COVID variants as well as other coronaviruses -- maybe even the ones responsible for the common cold. And it's dirt cheap -- less than $1 a dose, researchers say.

The vaccine targets a part of the COVID virus' spike protein that appears to be highly resistant to mutation and is common across nea...

Black people experience more severe courses of multiple sclerosis (MS), and now new research suggests that drugs commonly used to treat this disease may not work as well or for as long in these folks.

"I was amazed," said study researcher Dr. Gregg Silverman, a professor of medicine at NYU Langone Health in New York City. In a study of two drugs, "there was a dramatic and significant diff...

Two new studies out of Britain find that although the now-dominant "U.K. variant" of the new coronavirus does spread more quickly, it does not appear to lead to more severe disease in those made ill.

The findings should help allay fears that more patients will die after infection with the variant, officially labeled B.1.1.7.

Scientists published the findings online April 12 in two

COVID-19 might have a tough new foe: The sun.

New research shows that sunnier regions of the United States have lower COVID-19 death rates than cloudier areas, suggesting that the sun's UV rays might somehow provide some protection against the disease.

The effect is not due to better uptake of the healthy "sunshine vitamin," vitamin D, noted the Scottish research team led by Richard...

Fewer clinical trials are being completed during the pandemic, which experts say could affect medical research for decades to come.

Previously, it was reported that more than 80% of clinical trials were suspended between March 1 and April 26, 2020, with the pandemic cited as the main reason.

In this study, researchers at Penn State College of Medicine examined more than 117,000 tria...

At first glance, it appears that little will change between now and 2040 when it comes to the types of cancers that people develop and that kill them, a new forecast shows.

Breast, melanoma, lung and colon cancers are expected to be the most common types of cancers in the United States, and patients die most often from lung, pancreatic, liver and colorectal cancers, according to the lates...

There's good news for the millions of Americans who've already received a dose or two of Moderna's COVID-19 vaccine: New research shows the vaccine should protect against illness for at least six months.

The new study tracked 33 participants in the trials that led to the vaccine's approval. Six months after having received their second vaccine dose, "antibody activity remained high in al...

Because of the COVID-19 pandemic, scientists thought twice about studying North American bats in their winter habitats. But they've now determined that the risk of humans passing the coronavirus to bats under these conditions was low.

The U.S. Geological Survey (USGS) led the study. It found the risk to be one in 1,000 with no protective measures and one in 3,333 with proper use of per...

A new U.S. study offers more evidence that a single dose of a two-dose COVID-19 vaccine may provide enough protection to people who've previously been infected with the coronavirus.

"Our findings extend those from smaller studies reported elsewhere and support a potential strategy of providing a single dose of vaccine to persons with a confirmed prior history of coronavirus infection, al...
