Piece of Home NASA's Mars helicopter Ingenuity has officially spotted the remains of the parachute and back shell that allowed it and the much bigger Perseverance rover to touch down on the surface of the Red Planet over a year ago. Earlier this month, images taken by the rover's mast cam showed glimpses of the remains of the parachute from an estimated half a mile away. Now, we get a much closer
Scientists at the Babraham Institute have shown that two RNA binding proteins hold the key to a stronger immune response to influenza in mice. Their findings, published today in Nature Communications, reveal that the absence of these proteins changes the potency of T cells that arise at the start on an infection. Further research could lead to implications for therapies that harness the immune sys

Rare fossils from three of the late-Triassic marine reptiles found in Swiss Alps include 10cm tooth – big enough to snag giant squid The remains of a huge sea creature with enormous teeth that could have helped it capture giant squid have been found in the Swiss Alps. Ichthyosaurs were large marine reptiles with an elongated, snakey shape. They first emerged after the end of the Permian extinctio
US officials are still struggling to communicate about COVID-19 with the public. Take president Joe Biden's chief medical adviser Anthony Fauci, who attempted to say today that the US has weathered the storm, entering a new and less dangerous phase of the crisis. "We are certainly right now in this country out of the pandemic phase," he said during an interview with PBS NewsHour on Tuesday — a ra
As the earth's climate continues to warm, researchers predict wild animals will be forced to relocate their habitats—likely to regions with large human populations—dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.
Hydrogen and oxygen ions escaping from Earth's upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical Institute scientists.

The Minneapolis Police Department violated civil rights law through a pattern of racist policing practices, according to a damning report published today by the Minnesota Department of Human Rights. The report, which is the result of a two-year inquiry, found that officers stop, search, arrest, and use force against people of color at a much higher rate than white people, and covertly surveilled
For the world's viruses, this is a time of unprecedented opportunity. An estimated 40,000 viruses lurk in the bodies of mammals, of which a quarter could conceivably infect humans. Most do not, because they have few chances to leap into our bodies. But those chances are growing. Earth's changing climate is forcing animals to relocate to new habitats, in a bid to track their preferred environmenta
Paleontologists have discovered sets of fossils representing three new ichthyosaurs that may have been among the largest animals to have ever lived, reports a new paper in the peer-reviewed Journal of Vertebrate Paleontology.

When Briana Goodman gave birth to twins in 2015, she found herself surrounded by people telling her the best way to take care of her newborns. Any time she would bring up using a sleep-training method that encourages babies to cry it out and self-soothe, everyone seemed to have a judgmental opinion to share. But there was one place that Goodman, a clothing reseller in a suburb of Baltimore, could

As we try to transition as much as possible away from fossil fuels, jet fuel remains a tricky problem to solve. Jets, like rockets, require a fuel with a high energy density (energy per volume) and specific energy (energy per mass). For rockets the specific energy is far more important – mass is everything, due to the rocket equation – and so perhaps the ideal fuel for rockets is hydrogen, becaus
Hjärntumörformen glioblastom består av flera olika undergrupper. Det visar en ny studie som sett stor skillnad på överlevnad mellan patienterna i två av grupperna. Resultaten kan användas för att utveckla mer precisa behandlingsformer. Inlägget dök först upp på forskning.se .

In March 2020, the government stopped bugging me—and 40 million other Americans—for student-loan payments. It also stopped collecting interest on outstanding debt. And with so many other things to worry about, I largely stopped thinking about that debt. Some survey data indicate that many of my peers became similarly disengaged. Two years later, one estimate from the Committee for a Responsible F

The majority of Americans who insist that "cancel culture" is a problem and the minority who counter that it is a fraud, a myth, or a moral panic are too often talking past one another. One faction invokes the term cancel culture as shorthand for a range of complaints: for instance, that figures such as the political analyst David Shor and Emmanuel Cafferty , a California utility-company worker,
This month: Residents of Lebanon's Beqaa Valley say pollution in the Litani River is responsible for a host of chronic health problems. While a causal link is hard to prove, cleanup efforts are precarious amid the country's economic crisis and shifting blame between refugees and government inaction.
Graid Technology has released the latest version of its NVMe RAID solution, and it's a scorcher. Instead of using a typical hardware RAID controller it uses a GPU to do the heavy lifting. The goal is to squeeze the absolute maximum level of performance from NVMe drives. Apparently, that's exactly what it can do. The product is called the SupremeRAID SR-1010, and it is a hardware RAID controller f

A US government watchdog is warning that the Pentagon may have wasted more than $22 billion on Microsoft's HoloLens by failing to ask if the soldiers who would be theoretically responsible for deploying the hardware actually wanted to use it or perceived any benefit from doing so. This is an observation so banal, one might wonder why the government needed to put it in an audit in the first place.
