Mars Helicopter Flies Over NASA Wreckage
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

RNA binding proteins help T cells pick their weapons before battle
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

Elon Musk Isn't Buying Twitter to Defend Free Speech
Conservatives on Twitter have greeted Elon Musk as a liberator. The mega-billionaire is in the process of purchasing the social-media platform and reorienting it toward what he calls "free speech." The conservative columnist Ben Shapiro celebrated the news of the new free-speech era by insisting that Musk engage in politically motivated mass firings of Twitter workers based on their perceived pol

Giant ichthyosaur's huge tooth points to sea creatures with robust bite
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

Dr. Fauci Says the "Pandemic Phase" of COVID Is Over, Then Says Pandemic Is Actually Still Happening
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.

New study finds climate change could spark the next pandemic
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.

Minneapolis police used fake social media profiles to surveil Black people
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.

We Created the Pandemicene
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

The Communities Trapped on Facebook
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

Sustainable Jet Fuels
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

Why Hunter Biden's Laptop Will Never Go Away

Student-Loan Forgiveness Wouldn't Solve Much
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.

GPU-based NVMe RAID Melts Your Face at 110 Gigabytes Per Second
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

The US Government May Have Wasted $22 Billion on HoloLens
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.
