STAT reports: Nearly a year ago, amid concerns about how to prevent transmission of the virus causing Covid-19, scientists were beginning to conclude that rigorous disinfection of surfaces — say, fogging them or deep-cleaning with bleach — was overkill. Academics were warning that the risk of so-called fomite transmission was wildly overblown. In the fall,… Read More »
Zeynep Tufekci writes: A few sentences have shaken a century of science. A week ago, more than a year after the World Health Organization declared that we face a pandemic, a page on its website titled “Coronavirus Disease (Covid-19): How Is It Transmitted?” got a seemingly small update. The agency’s response to that question had… Read More »
Nature reports: NASA is best known for exploring other worlds, whether that’s sending astronauts to the Moon or flying helicopters on Mars. But under US President Joe Biden, the space agency intends to boost its reputation as a major player in studying Earth — especially with an eye towards fighting climate change. “Biden made clear… Read More »
NBC News reports: Paola Bezzon thought her sniffles in December were just a seasonal cold until a serology test months later found coronavirus antibodies in her blood. And not just normal levels of antibodies. Researchers say she is “super-immune” — a person whose body seems to make more antibodies than normal. “I don’t know why… Read More »
By Nerys M Astbury, University of Oxford; Carmen Piernas, University of Oxford, and Min GAO, University of Oxford From the start of the pandemic, it was clear that some people who were infected with the coronavirus were experiencing more severe illness, which increased their chances of being hospitalised, admitted to an intensive care unit (ICU)… Read More »
CNBC reports: The risk of being exposed to Covid-19 indoors is as great at 60 feet as it is at 6 feet — even when wearing a mask, according to a new study by Massachusetts Institute of Technology researchers who challenge social distancing guidelines adopted across the world. MIT professors Martin Z. Bazant, who teaches… Read More »
Nature reports: The pandemic is sweeping through India at a pace that has staggered scientists. Daily case numbers have exploded since early March: the government reported 273,810 new infections nationally on 18 April. High numbers in India have also helped drive global cases to a daily high of 854,855 in the past week, almost breaking… Read More »
The New York Times reports: Could getting too little sleep increase your chances of developing dementia? For years, researchers have pondered this and other questions about how sleep relates to cognitive decline. Answers have been elusive because it is hard to know if insufficient sleep is a symptom of the brain changes that underlie dementia… Read More »
CNN reports: Doctors say they are honing in on the cause of blood clots that may be linked with certain coronavirus vaccines, and add their findings have important implications for how to treat the condition, regardless of whether vaccines cause it. Even though the link is not firm yet, they’re calling the condition vaccine-induced immune… Read More »
Roxanne Khamsi writes: For weeks, Americans looked on as other countries grappled with case reports of rare, sometimes fatal blood abnormalities among those who had received the AstraZeneca vaccine against COVID-19. That vaccine has not yet been authorized by the FDA, so restrictions on its use throughout Europe did not get that much attention in… Read More »
Sarah Zhang writes: A year ago, when the United States decided to go big on vaccines, it bet on nearly every horse, investing in a spectrum of technologies. The safest bets, in a way, repurposed the technology behind existing vaccines, such as protein-based ones for tetanus or hepatitis B. The medium bets were on vaccines… Read More »
STAT reports: A week after receiving the AstraZeneca Covid-19 vaccine, a 37-year-old woman in Norway went to the emergency department with fever and persistent headaches. A CAT scan of her head showed a blood clot in blood vessels involved in draining the brain, but her levels of platelets, involved in clotting, were low. She was… Read More »
The New York Times reports: She grew up in Hungary, daughter of a butcher. She decided she wanted to be a scientist, although she had never met one. She moved to the United States in her 20s, but for decades never found a permanent position, instead clinging to the fringes of academia. Now Katalin Kariko,… Read More »
The New York Times reports: When the coronavirus began to spread in the United States last spring, many experts warned of the danger posed by surfaces. Researchers reported that the virus could survive for days on plastic or stainless steel, and the Centers for Disease Control and Prevention advised that if someone touched one of… Read More »
The New York Times reports: A test flight for researching ways to cool Earth by blocking sunlight will not take place as planned in Sweden this June, following objections from environmentalists, scientists and Indigenous groups there. The Swedish Space Corporation said this week it had canceled plans for the flight, in which it would have… Read More »
Science Alert reports: A team of scientists is calling for greater research into how sunlight inactivates SARS-CoV-2 after realizing there’s a glaring discrepancy between the most recent theory and experimental results. UC Santa Barbara mechanical engineer Paolo Luzzatto-Fegiz and colleagues noticed the virus was inactivated as much as eight times faster in experiments than the… Read More »
