An experimental injectable drug appears more versatile than existing medications in treating people with different forms of severe, hard-to-control asthma, clinical trial results show.

There are many different types of asthma brought on by many different triggers, and a number of monoclonal antibody medications -- called "biologics" -- have been crafted to target distinct asthma triggers....

An ambitious new vaccine effort is taking aim at future coronavirus mutations that may threaten global health down the road.

So far, the "pan-coronavirus vaccine" has proven 100% effective in testing among monkeys, investigators reported.

"Large outbreaks of coronaviruses have occurred three times in the last 18 years," explained study author Kevin Saunders, director of researc...

A microchip implanted in the brain has allowed a paralyzed man to communicate by text -- at speeds that approach the typical smartphone user.

The achievement is the latest advance in "brain-computer interface" (BCI) systems.

Scientists have been studying BCI technology for years, with the aim of one day giving people with paralysis or limb amputations greater independence in their ...

Not only have humans and their ancient ancestors been eating carbs for longer than was realized, but a new study finds these starchy foods may actually have played a part in the growth of the human brain.

A new study researching the history of the human oral microbiome found that Neanderthals and ancient humans adapted to eating starchy foods as far back as 100,000 years ago, which is mu...

Two widely used COVID-19 vaccines -- Pfizer and Moderna -- will likely remain powerfully protective against developing serious illness even if coronavirus variants somehow manage to infect vaccinated patients, new research suggests.

Both vaccines are based on messenger RNA (mRNA) technology. And investigators say that, at least in theory, such technology can deploy multiple levels of defe...

While COVID-19 research efforts must now shift toward the development of a pill that can prevent serious illness in the recently infected, experts say.

"We need a pill that can keep people out of the hospital, and the time to develop that is right now," Dr. Rajesh Gandhi said during a Thursday media briefing by the Infectious Diseases Society of America. He is director of HIV Clinical Ser...

The Middle East and North Africa are already among the hottest spots on the planet, but new research warns that if nothing is done to slow climate change there will be life-threatening heat waves with temperatures of 132 Fahrenheit or higher in those regions.

"Our results for a business-as-usual pathway indicate that, especially in the second half of this century, unprecedented super- a...

Like many proud moms, Lisa Stockman-Mauriello of Summit, N.J., is looking forward to exciting milestones in lives of her three sons over the coming months: One will graduate college, one will enter college, and the third will begin high school.

But unlike other moms, it's not guaranteed that she'll be there to experience them.

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...

It's the question everyone wants answered because reopening the world depends on it: Can coronavirus vaccines stop transmission of the virus?

Now, 21 universities across the United States are teaming up to find out.

The project, called Prevent COVID U, was started by the COVID-19 Prevention Network housed at the Fred Hutchinson Cancer Research Center in Seattle.

The study inc...

When people die some cells in their brains go on for hours, even getting more active and growing to gargantuan proportions, new research shows.

Awareness of this activity, spurred on by "zombie genes," could affect research into diseases that affect the brain.

For the study, researchers analyzed gene expression using fresh brain tissue collected during routine surgery and found that...

For those who suffer painful arthritis in their aging knees, new research suggests a noninvasive treatment might deliver lasting relief.

Called genicular artery embolization, the roughly two-hour catheter treatment involves a once-and-done injection of tiny hydrogel particles into arterial pathways in the knee joint. The goal: To decrease overall blood flow in the joint, and thereby marke...

Daily insulin jabs can be the bane of existence for people who live with type 2 diabetes, but an investigational once-weekly insulin shot may be a game changer for these folks.

While the research is still in its early stages, the new drug called basal insulin Fc (BIF) is given once a week and appears to be just as effective at controlling blood sugar (glucose) as insulin degludec, the gol...

An antibody infusion being tested for preventing HIV does not seem to thwart most infections -- but its success against certain strains of the virus suggests researchers are on the right track.

That's the takeaway from a clinical trial that put the antibody, called VRC01, to the test in 2,700 people at high risk of contracting HIV.

Researchers found that infusions of the antibody ev...

Research into miscarriages, infertility and birth defects is now primed to undergo revolutionary advances, thanks to the creation in the lab of an early stage of human embryos by two separate international teams of scientists.

Both teams were able to use human cells to create artificial blastocysts, an early stage of conception that occurs a few days after egg fertilization but prior...

Humans sweat more and move more than chimpanzees and other apes, but new research shows people are actually more water-efficient than their primate cousins.

For the first time, scientists say they measured precisely how much water humans lose and replace each day compared with their closest living animal relatives.

The investigators found that the human body uses 30% to 50% less wat...

Cotton masks provide better protection against the new coronavirus than those made with synthetic fabrics, researchers say.

In a new study, investigators tested different mask fabrics under conditions that mimic the humidity of a person's breath in order to assess how the fabrics perform in actual use.

Under humid conditions, filtration efficiency (a measure of how well a material c...

If a nice hot cup of tea sounds good to you, there's even more reason to enjoy one now. Scientists have gained new insight into how tea helps lower blood pressure, perhaps pointing the way to new types of blood pressure medications.

The researchers found that certain compounds in both black and green tea help relax blood vessels by activating ion channel proteins in the walls of blood ves...

Just two weeks of treatment with an experimental drug can delay the onset of type 1 diabetes by several years, researchers report.

The drug, called teplizumab, is already under review by the U.S. Food and Drug Administration based on earlier evidence of its effectiveness.

If it gets the green light, it would become the first drug approved for delaying type 1 diabetes in high-risk pe...

Researchers who recorded the most detailed images ever made of newborns' lungs as they took their first breaths say the breakthrough could improve treatment of breathing problems in babies.

"Respiratory problems are the most common reason we need to treat babies in intensive care," said researcher David Tingay of Murdoch Children's Research Institute in Melbourne, Australia.

"This n...

Many women suffer through countless urinary tract infections (UTIs), but a new study in mice offers hope that a vaccine could one day bring their nightmares to an end.

"Although several vaccines against UTIs have been investigated in clinical trials, they have so far had limited success," said senior study author Soman Abraham, a professor of pathology, immunology and molecular genetics &...

The first U.S. case of a Brazilian COVID-19 variant that doctors fear can re-infect the previously sick surfaced in Minnesota in early January 2021, and the more infectious variant has since been found in four other states, a new government report says.

Known as the P.1 variant, it first appeared in a Minnesotan who'd recently traveled to southeastern Brazil, according to Melanie Fireston...

Researchers have identified 44 new genetic variants associated with glaucoma, a leading cause of blindness. They say their findings could provide new targets to treat the common eye disease.

In their study, the international team compared the genes of more than 34,000 people with glaucoma and more than 349,000 people without the incurable eye condition.

In addition to pinpointing th...

Spinal cord injuries can be devastating to the more than 17,000 Americans who suffer them each year. But many patients may have new reason for hope: Early research suggests infusions of stem cells could help them regain lost sensation and movement.

These improvements may occur within days or weeks of receiving the stem cell therapy, and can last at least six months, according to the small...

The world's researchers have worked at a breakneck pace during the COVID-19 pandemic.

Through October, more than 87,000 papers about the new coronavirus were published worldwide. That's a remarkable number even given the significance of the pandemic, according to the researchers who tallied them all up.

"It is an astonishing number of publications -- it may be unprecedented in the h...

Protective immune system antibodies that develop after being infected with COVID-19 last for at least a few months, a new study suggests. And reinfection does seem to be relatively rare.

That could have big implications for public health and societies, including allowing people to return to physical workplaces and go to school, the researchers said.

"The data from this study suggest...

Researchers have identified more than 140,000 viruses that live in the human gut, including half that were previously unknown.

The number and variety of viruses found in more than 28,000 gut microbiome samples gathered from different parts of the world are surprisingly high, according to the study authors.

The researchers added that their findings will lead to new research to learn ...

One of the least understood effects of COVID-19 infection is "brain fog," a kind of mental confusion that can take hold among seriously ill patients, sometimes lingering long after recovery.

Now, a new study has spotted a possible neurological clue in the form of highly unusual cell clusters in the brains of people who had COVID-19.

"What we're talking about is a situation where pat...

It would be nice if it were true, but a bout of the common cold won't protect you against the new coronavirus infection, researchers report.

Colds are caused by seasonal coronaviruses (CoVs) and previous studies have suggested that exposure to cold coronaviruses may safeguard against the SARS-CoV-2 coronavirus that causes COVID-19.

To find out if that was true, researchers analyzed...

A new weight-loss drug is almost twice as effective as current medications, clinical trial results show, and experts say it could revolutionize the treatment of obesity.

Overweight and obese people lost an average 15% of their body weight using a weekly injectable 2.4 milligram dose of semaglutide (Ozempic), a new report reveals.

What's more, one-third of all participants lost 20% o...

Could it be that a strange-looking creature known as a pangolin was the conduit by which the new coronavirus jumped to humans and prompted an international pandemic?

New research suggests the theory is a plausible one.

Pangolins are sold for food in live-animal "wet markets" in China -- facilities that have long been suspected of being ground zero for the spread of viruses originati...

An experimental antiviral drug known as peginterferon lambda can speed up COVID-19 patients' ability to shed the virus and recover, scientists report.

"One of the important things about this treatment that's different from the other things that have been studied for COVID-19 is that this is working on the person, not on the virus. So it doesn't depend at all on the strain or the sequence ...

A virus-linked cancer killing California sea lions is sounding a chilling alarm for mankind.

Exposure to environmental toxins significantly boosts risk for the herpes-like cancer, which was discovered in sea lions in 1979.

Since then, between 18% and 23% of adult sea lions admitted to a California animal rescue-and-research center have died of the disease. That's the highest rate f...

The death rate among COVID-19 patients in intensive care has fallen since the start of the pandemic, largely because of better treatments. But a new study review suggests that those advances in care may have plateaued.

The new analysis looked at data from 52 studies in North America, Europe, China and elsewhere, conducted up to October 2020 and including more than 43,000 patients.

T...

Stroke survivor Ken Allsford focused intensely on how he wanted to bend his elbow.

And then the robot exoskeleton attached to his left arm obeyed his unspoken command, moving his crippled limb.

"It was a combination of exciting and trepidation, because sometimes nothing would happen," Allsford, 61, of Katy, Texas, recalled. "But when you actually see it move without actually making ...

Like influenza, could COVID-19 evolve to wax and wane with the seasons? New research suggests it might.

Early in the pandemic, some experts suggested that SARS-CoV-2 -- the virus that causes COVID-19 -- may behave like many other coronaviruses that circulate more widely in fall and winter.

To find out if that could be true, researchers analyzed COVID-19 data -- including cases, deat...

Previous exposure to other coronaviruses may enhance a person's immune response to COVID-19 infection, but new research suggests that antibodies triggered by the SARS outbreak of 2003 provide only limited protection against the new coronavirus.

Antibodies are blood proteins made by the immune system to protect against infection, the Oregon Health & Science University (OHSU) researchers ex...

The new coronavirus is mutating in an attempt to elude vaccines and treatments, putting a greater onus on Americans to get vaccinated and use social distancing measures to avoid infection, U.S. health officials said Friday.

New COVID-19 variants out of South Africa and Brazil -- B.1.351 and P1, respectively -- contain a mutation called E484K, "which results in changes in the shape of the ...

An experimental gene therapy for Duchenne muscular dystrophy shows promise, a small study suggests.

The severe form of muscular dystrophy -- which affects about one in 3,500 males born each year in the United States -- causes muscles to progressively weaken and lose the ability to regenerate after an injury.

Muscle tissue is eventually replaced by fat and collagen. Many children wit...

To the ever-growing list of COVID-19's collateral damage, add one more casualty: cancer research.

A new study indicates that during the first wave of the pandemic last spring, the number of newly launched cancer treatment studies cratered by 60%.

"In short, the first wave of COVID slowed scientific progress in a health-related area distant from the disease itself," said study author...

Previous coronavirus infections might prime the immune system to fight the new coronavirus that causes COVID-19, a new study suggests.

There are numerous types of coronaviruses, including many harmless ones that cause mild upper respiratory infections similar to the common cold.

Besides SARS-CoV-2 -- the virus that causes COVID-19 -- other deadly coronaviruses include MERS-CoV, whic...

A promising step toward using retinal cell transplants to treat blindness is reported in a new study.

Adult retinal stem cells from deceased human donors survived when they were transplanted into the eyes of non-human primates, according to the researchers.

The cells were taken from the retinal pigment epithelium (RPE). It is a layer of cells that supports and nourishes the retina, ...
