The study that NIAID did fund by those researchers, also in Tunisia, involved evaluating a vaccine for leishmaniasis, a parasitic disease transmitted by sand flies that infects both humans and dogs. Twelve dogs were given the vaccine and then put in a fenced-in open space outside during high sand fly season, NIAID said, to see if the dogs still became infected. That study is ongoing, though NIAID’s funding has ended. None of the dogs have been euthanized, NIAID said.

A new study suggests the type of fat a person eats rather than the amount may be a more important factor in determining stroke risk. >> Read more trending newsThe study, reported by NBC News, found eating more animal fat led to a higher risk of stroke. A lower risk of stroke was linked to vegetable sources. Participants who ate the most animal fat (like processed meat) were 16% more likely to have strokes than those who ate the least. Researchers recommend people reduce eating red and processed meat, trim fat from meat, and cook with non-tropical vegetable oils where possible.

Pfizer and BioNTech said Thursday that their COVID-19 vaccine is "highly effective" after a new study showed it is more than 91% effective in preventing the disease. The study is based on more than 46,000 trial participants, the companies said on Thursday. Among those participants, there were 927 confirmed symptomatic cases of COVID-19, with 850 cases of COVID-19 in the placebo group and 77 cases recorded among people who received the vaccine. Pfizer announced in a news release that the vaccine is 91.3% effective six months after people get their second dose. The analysis also found that the vaccine was 100% effective in preventing COVID-19 cases in South Africa, where the coronavirus variant B.1.351 is prevalent.

Can wearing glasses protect against COVID-19? A news study suggests the answer is yes. The study, out of India, found people who wear glasses are three times less likely to get the virus because they’re less likely to touch their eyes, WABC-TV reported. [TRENDING: Tiger Woods’ leg shattered in rollover crash | Orlando City player faces sex charge | Woman loses $100,000 to romance conman]AdThe study, conducted last summer in Kanpur Dehat, involved 304 patients, ages 10 to 80.

A new report found that 40% of America’s COVID-19 deaths could have been prevented, the Lancet Commission on Public Policy and Health found that many people didn’t take the pandemic seriously at the beginning. Commission co-chair Dr. Steffie Woolhandler says public health measures such as mask wearing and physical distancing could have saved lives. However, Woodhandler says former President Donald Trump failed to create a national response, instead leaving crucial decisions to states. [TRENDING: Man in Capitol riot arrested at Orlando airport | Tom Brady throws Lombardi Trophy | How to get the vaccine in Fla.]AdBut that was only part of the problem, the commission says America’s poor health system also contributed to deaths.

In the age of COVID-19, it’s something we constantly keep around us, but hand sanitizer can be dangerous. Cases of chemicals from hand sanitizers getting into young eyes increased 7-fold between April 1 and Aug. 24, 2020, compared to the same period a year earlier. Weber knows about the dangers of eye exposures to hand sanitizer as she’s had these calls come into the center. To keep kids safe, Weber says parents should keep hand sanitizer out of reach of younger children. Weber says you should call the nationwide poison control hotline at 1-800-222-1222 if your child gets hand sanitizer in an eye.

People who live here may disagree, but Florida is not the best or the worst state to drive in, at least according to a recent study from WalletHub. The study puts Florida firmly in the middle of the pack, ranking the Sunshine State at No. 27, with Texas being the best state to drive in and Hawaii being the worst. According to the study, the state ranks number two when it comes to most car washes per capita. On the negative side, Florida is among the states with the highest percentage of rush-hour traffic congestion.

Dogs may be able to be trained to detect COVID-19, according to a study published on Thursday. Detection dogs, like those that sniff drugs or explosives at airports, are taught to sniff for certain infections and diseases. Now, some countries are exploring the possibility of using those types of dogs as a rapid, reliable and relatively cheap way to pre-screen people for COVID-19. Six dogs had their sniffing abilities put to the test and performed dozens of trials, with a success rate of 76-100%. The study was published Thursday in the peer-reviewed journal PLOS ONE.

Researchers have found that ultrasounds give a better indication of which COVID-19 patients have a higher risk of dying. Doctors at hospitals across the Mount Sinai system in New York looked at echocardiograms, or ultrasound scans of the heart, for 305 COVID-19 patients and 190 of those had structural heart damage. The scans gave doctors an indication of which patients had the highest risk for death. [TRENDING: ‘Smell of rotting flesh’ leads to body in trunk | How to celebrate Halloween during pandemic | 98 ‘murder hornets’ removed]Researchers found it gave a fuller picture than the routinely run blood tests to look for heart damage.

As humanity ramps up its search for alien life , we should keep in mind that E.T. A new study makes that point by identifying more than 1,000 nearby stars that are favorably positioned for spotting life on Earth. "And we can even see some of the brightest of these stars in our night sky without binoculars or telescopes," Kaltenegger said. Soon, researchers will also be able to scan the atmospheres of some nearby transiting planets for potential signs of life. This search turned up 1,004 qualifying main-sequence stars — stars that, like our sun, fuse hydrogen into helium in their cores.

It’s starting to look like people with the O blood type may have an advantage in the global pandemic. A Danish study found among more than 470,000 people tested for coronavirus, only 38% with blood type O tested positive, even though 41% of the population have type-O blood. [TRENDING: Woman stranded from home for 8 months | Video shows mountain lion stalking hiker | Moon rules: Must come in peace]A Canadian study found among 95 patients critically ill with COVID-19, a higher proportion with blood type A or A/B needed mechanical ventilation compared with patients with blood group O or B. The research gives further evidence blood type may play a role in someone’s susceptibility to infection and just how serious their illness is. The reasons for this link aren’t clear and experts say more research is needed.

Powerful stellar eruptions could pose a serious challenge to the origin and evolution of life around the universe , a new study suggests. Such outbursts throw off large amounts of ultraviolet (UV) radiation, which is not only directly harmful to life as we know it but can also strip away the atmospheres of relatively close-orbiting planets. These issues are especially pronounced for worlds circling red dwarfs , small and dim stars that make up about 75% of the Milky Way galaxy's stellar population. For starters, red dwarfs are more active than sunlike stars, especially when they're young. Researchers calculated the likely UV emissions generated by red-dwarf superflares, as well as the radiation loads absorbed by rocky planets that might reside in the small stars' habitable zones.

Scientists at Florida Atlantic University are experimenting with different nonmedical masks to find the most effective face covering to help stop the spread of COVID-19. They "delivered" a sneeze or cough from a mannequin head wearing varying face coverings and used lasers to detect respiratory droplets. Droplets from a bandana-covered cough traveled 3 feet. With a folded cotton handkerchief, droplets traveled 1 foot, 3 inches, and with the cone-style masks, they traveled about 8 inches. Stitched-quilting fabric masks were the most effective, with droplets traveling 2.5 inches.
