After five days of symptoms or a positive COVID-19 test, about 31% of people are still contagious. After 10 days, 5% are infectious, UKHSA data shows.
Marin Konstadt, visiting family in Florida, was at the opera in 2020 when she got a call on her cellphone. She called back at intermission. The caller, a genetics specialist at a hospital, had some important news for her. She has a genetic variant that can increase her disease risk. Did she want to know more? Konstadt, 69, a psychiatric nurse practitioner who lives in Salem, Massachusetts, had been thrust like many other Americans into a raging debate on medical ethics and genetics. In 2016, she
If a rock falls on Mars, and no one is there to see it, does it leave a trace? Yes, and it’s a beautiful herringbone-like pattern, new research reveals. Scientists have now spotted thousands of tracks on the red planet created by tumbling boulders. Delicate chevron-shaped piles of Martian dust and sand frame the tracks, the team showed, and most fade over the course of a few years. Rockfalls have been spotted elsewhere in the solar system, including on the moon and even a comet. But a big open q
Hilton's wellness-focused rooms, which include an exercise bike, TRX bands, and guided workouts felt like the perfect getaway for fitness fanatics.
If all goes well, Webb will be 100 times more powerful than Hubble — so sensitive to infrared light that it could detect the faint heat of a bumble bee as far away as the moon.
The limestone statues found in the 'Temple of a Million Years' in Luxor, Egypt, depicted King Amenhotep III with a lion's body and a human head.
NASA has chosen 57 winning teams — including a team from Interlake High School in Bellevue, Wash.— to receive funding to build and fly experiments focusing on subjects ranging from lunar dust mitigation to inkjet printing in zero gravity. Interlake’s team will focus on a more down-to-Earth scientific question: how pollution levels are correlated with altitude. The prizes were awarded through NASA’s first-ever TechRise Student Challenge, which aims to give students in grades 6 through 12 an oppor
One of Saturn's smallest moons wasn't a candidate for alien life. But if Mimas has an ocean, it could point to a new class of "stealth" water worlds.
Data for the weeks ending January 1 and 8 showed that when infections spiked citywide, vaccinated New Yorkers were less likely to get COVID-19.
Covid vaccine booster shots offer strong protection against hospitalization from the omicron variant, 3 studies from the CDC published Friday find.
Booster shots appear to be at least 90% effective against hospitalization for both Delta and Omicron, new CDC data show.
Three studies released Friday offered more evidence that COVID-19 vaccines are standing up to the omicron variant, at least among people who received booster shots. The papers echo previous research — including studies in Germany, South Africa and the U.K. — indicating available vaccines are less effective against omicron than earlier versions of the coronavirus, but also that boosters doses rev up virus-fighting antibodies to increase the chance of avoiding symptomatic infection. It found vaccine effectiveness was best after three doses of the Pfizer or Moderna vaccines in preventing COVID-19-associated emergency department and urgent care visits.
Hidden deep in the Peruvian jungle and shrouded beneath thick foliage, archaeologists have discovered a series of long-forgotten structures among the sprawling
The achievement could help revolutionize organ donation as shortages create yearslong waits for transplants.
Antibiotic-resistant germs caused more than 1.2 million deaths globally in one year, according to new research that suggests that these “superbugs" have joined the ranks of the world's leading infectious disease killers. The World Health Organization has been citing a global estimate — several years old — that suggested at least 700,000 people die each year due to antimicrobial-resistant germs. Antimicrobial resistance happens when germs like bacteria and fungi gain the power to fight off the drugs that were designed to kill them.
Humans and climate change are killing the world's reefs. The latest discovery of one of the largest deepwater reefs offers hope they can survive.
The huge new CDC data set backs up what other studies have found: that Moderna is edging out Pfizer and that J&J is offering less protection.
“Cooking is the No. 1 way you’re polluting your home … You’re basically living in this toxic soup.”
“People (myself included) like cooking with gas! It’s one of the few energy uses that inspires brand loyalty to the fuel consumed.”
“It’s time to start making new buildings all-electric and switching out all those existing gas appliances, including gas stoves.”
“If you're looking for personal ways to protect the environment and your health right now, you have much bigger fish to fry.”
“Market-based solutions have not achieved their desired goals, thus new ways of thinking need to emerge.”
