It's been more than six months since Brandy Compton last landed in a hospital emergency room.

That's an amazing medical achievement, brought about by scientific breakthroughs that have been unfortunately overshadowed by the coronavirus pandemic, experts say.

Compton, 31, was born with sickle cell disease, a genetic condition that primarily affects people of African descent.

T...

Aiming to deliver a one-two punch to the herpes virus, animal research on an experimental drug found it tackled active infections and reduced or eliminated the risk of future outbreaks.

Existing treatments, such as Zovirax, Valtrex or Famvir, are only effective at the first task; they can help treat cold sores and genital eruptions once a herpes outbreak occurs. But...

The vast majority of editors at leading medical journals are white - with few of those influential spots going to Black or Hispanic professionals, a new study finds.

The study comes on the heels of a controversy that prompted the resignation of the editor-in-chief of the Journal of the American Medical Association.

It all started in February when Dr. Ed Livingston...

Researchers are using mice to study a potential new treatment that could help patients who have sickle cell disease, without some of the risks and side effects of existing therapies.

The investigators reported using genetic-based editing on mice to convert a disease-causing hemoglobin gene to a benign variant that would enable healthy blood cell production.

Sickle cell disease (SCD...

The first drug ever shown to slow the progression of Alzheimer's disease could be approved by the U.S. Food and Drug Administration on Monday, but experts say that approval will be surrounded by controversy.

In clinical trials, aducanumab showed a 22% reduction in the development of thinking and memory problems associated with Alzheimer's disease, according to a statement from the Alzheim...

Reacting to recent controversy, the American Medical Association (AMA) announced Thursday a series of steps it will take to promote diversity, equity and inclusion within the medical society and its network of 12 influential journals.

Dr. Howard Bauchner, editor-in-chief of the Journal of the American Medical Association (JAMA), is stepping down at the end of June, forced out ov...

The U.S. government and nonprofits are replacing drug companies as the main drivers of Alzheimer's disease research, two new studies show.

The findings are from an analysis of national data by Jeffrey Cummings, a research professor at the University of Nevada, Las Vegas School of Integrated Health Sciences.

In one study, his team found that the number of Alzheimer's clinical trials ...

People with spinal cord injuries can overwork their shoulders as they move about in a wheelchair, and that often leads to chronic shoulder pain.

However, a small study suggests that an injection of the patient's own fat cells can help ease the pain.

The injected cells cushion the joint and may repair it, the researchers explained. Most important, they said that the procedure - calle...

Moderna's coronavirus vaccine fully protects children aged 12 to 17, the company announced Tuesday.

In a clinical trial that included more than 3,700 young volunteers, there were no cases of symptomatic COVID-19 infection in the two-thirds of participants who received both doses of the vaccine, which translates into an efficacy rate of 100%.

That's the same rate that was reported re...

Doctors for the first time have used a form of gene therapy to restore partial vision in a blind person, according to findings announced Monday.

The research team genetically altered retinal ganglion cells to become light-sensitive in a man whose vision was destroyed by retinitis pigmentosa, a genetic disorder that breaks down cells that absorb and convert light into brain signals.

...

Studies that can't be verified and may be untrue are much more likely to be cited in the media because they tend to be more interesting, researchers report.

They looked at studies in top psychology, economic and nature/science journals and found that only 39% of 100 psychology papers were successfully replicated. The replication rates were 61% for 18 economic studies, and 62% amo...

If you've ever wished you had an extra hand to accomplish a task, never fear, scientists are working on that. But a new study raises questions about how such technology could affect your brain.

The findings come from ongoing research into a 3D-printed robotic thumb known as "Third Thumb." It's worn on a person's dominant hand, making it capable of feats that normally demand both hands.

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- an...

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.

"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...
