The story of how my health took such a dramatic turn for the better amid the coronavirus lockdown dovetails with another healthy change in my life.
From snapshots of Jezero Crater to 360-degree panoramas, here are some of the highlights captured by the US space agency's rover.
Sharks use the Earth's magnetic field as a sort of natural GPS to navigate journeys that take them great distances across the world's oceans, scientists have found. Researchers said their marine laboratory experiments with a small species of shark confirm long-held speculation that sharks use magnetic fields as aids to navigation — behavior observed in other marine animals such as sea turtles. “We know that sharks can respond to magnetic fields," Keller said.
A Falcon 9 SpaceX rocket shot up from Kennedy Space Center in Cape Canaveral, Florida at 6:56 p.m. EDT.
John Kerry, President Joe Biden’s climate envoy, met privately with Pope Francis on Saturday, afterward calling the pope a “compelling moral authority on the subject of the climate crisis” who has been “ahead of the curve.” The former U.S. Secretary of State told Vatican News that the pope's embrace of climate issues “hopefully can push people to greater ambition to get the job done.”
As Dartmouth College sophomore Nicholas Sugiarto flipped through the course catalog last semester, two words caught his eye: “Asian American.” The 19-year-old Chinese Indonesian American didn't know Asian American-focused classes were even an option at the Hanover, New Hampshire, campus. The biomedical-engineering major ended up enrolling in “Gender and Sexuality in Asian American Literature" and now wishes he could minor in Asian American studies.
Microbes that may accidentally have been brought to the Red Planet could potentially wreak havoc, according to scientist Christopher Mason
Two satellites for BlackSky’s Earth observation constellation were lost today when the second stage of Rocket Lab’s Electron launch vehicle suffered an anomaly, just minutes after liftoff from New Zealand. Rocket Lab said the mission failure was under investigation. “The issue occurred shortly after stage two ignition,” the company said in a tweet. The live stream for launch showed what appeared to be a successful launch at 11:11 p.m. New Zealand time (4:11 a.m. PT), followed by a stage separation that went according to plan. However, it looked as if the second stage’s rocket engine shut down and failed to… Read More
An unusual study that had thousands of heart disease patients enroll themselves and track their health online as they took low- or regular-strength aspirin concludes that both doses seem equally safe and effective for preventing additional heart problems and strokes. “Patients basically decided for themselves” what they wanted to take because they bought the aspirin on their own, said Dr. Salim Virani, a cardiologist at Baylor College of Medicine in Houston who had no role in the study. Aspirin helps prevent blood clots, but it’s not recommended for healthy people who have not yet developed heart disease because it carries a risk of bleeding.
COVID-19 infections in adults of all ages fell by 80% five weeks after a first dose of Pfizer, Moderna or AstraZeneca vaccine, according to Italian research published on Saturday. The first such study by a European Union country on the real-world impact of its immunisation campaign was carried out by Italy's National Institute of Health (ISS) and the Ministry of Health on 13.7 million people vaccinated nationwide.
A single lone star tick bite could cause hives, shortness of breath, or even death. And it's making Americans allergic to red meat.
The Zhurong rover is almost ready to start scanning Mars' volcanic-rock fields for hidden water ice. Such reserves could help future Mars astronauts.
China landed a spacecraft on Mars for the first time on Saturday, a technically challenging feat more difficult than a moon landing, in the latest step forward for its ambitious goals in space. It will join an American rover that arrived at the red planet in February. China’s first Mars landing follows its launch last month of the main section of what will be a permanent space station and a mission that brought back rocks from the moon late last year.
The jab didn't even hurt, and Mabel Aguilera figures it may finally let her see granddaughters on the other side of Cuba who she hasn't glimpsed during many months of pandemic restrictions. Aguilera is among hundreds of thousands of Cubans who have begun receiving new, locally produced vaccines against COVID-19 in the past few days as the socialist government has ramped up an inoculation campaign — even before releasing formal Phase III data on the vaccines' effectiveness and safety. The campaign is being closely watched by many across Latin America and the world who see Cuba's vaccines as a possible way to ease global shortages.
Update for 6:30 a.m. PT May 15: Two BlackSky satellites were lost when the second stage of Rocket Lab’s Electron rocket suffered an anomaly, minutes after liftoff from New Zealand. “We are deeply sorry to our customers Spaceflight Inc. and BlackSky for the loss of their payloads,” Rocket Lab said in a statement. The cause of the anomaly is under investigation. Check out this story for updates. Previously: Satellites for BlackSky’s constellation of Earth-watching spacecraft may be launched from as far away as New Zealand, but their path to orbit features prominent stops in the Seattle area. BlackSky’s Global satellites… Read More
China's Tianwen-1 mission could be the first to deploy an orbiter, lander, and rover all at once. But only half of Mars landings have succeeded.
The stratosphere - the layer of Earth's atmosphere between 7.5 and 31 miles up - is shrinking due to greenhouse-gas emissions, a new study found.
Advocates of the paleo diet assume that our human ancestors had a meat-heavy, low-carb diet. But research shows Neanderthals ate many starchy foods.
The CDC changed its guidance to say fully vaccinated people could take off their masks indoors and outdoors in most settings.
China's National Space Administration said its Tianwen-1 spacecraft is expected to land on Mars between May 15 and May 19 local time.
China says its Mars probe and accompanying rover are expected to land on the red planet sometime between Saturday and Wednesday Beijing time. The China National Space Administration said in a brief notice that the Tianwen-1 probe has collected a large amount of scientific data since entering Mars orbit on Feb. 10 and the window for setting down on an icy area of the planet known as Utopia Planitia was determined by “current flying conditions.” The mission is the first attempt at a soft landing on Mars by a Chinese spacecraft.
“If Facebook lets Trump back on Facebook and Instagram, he'll assuredly restart his assault on democracy.”
“Facebook should have known better than to believe that it could limit speech on its platform without setting a terrible precedent.”
“Providing a microphone and an amplifier for deceit isn't fighting the good fight for free speech.”
“It’s no defense of Mr. Trump’s conduct to say that the digital public square shouldn’t suppress speech by political leaders.”
“The former president no longer gets the ‘head of state’ exception to terms of service.”
