The United States has seen a dramatic surge in coronavirus infections with less than two months to go before the start of the school year. With little indication that the country has even started to flatten the curve, there are serious questions about which areas of the country are positioned to open schools safely. But, for reasons that remain unclear, the Trump administration has a firm answer: all of them.
Over the past couple weeks, the administration exerted pressure on the Centers for Disease Control, instituted restrictive rules for foreign college students, and had several senior administration figures, including Trump himself, join in the push to have schools open. The push places the administration at odds with public health experts and its own CDC, which advises a far more cautious approach, as revealed in an internal document that leaked over the weekend.Pro open
At an event on Monday, President Trump reiterated his administration's message, saying, "Schools should be opened—kids want to go to schools." But, in keeping with his administration's approach to health policy, he followed that up with an evidence-free and likely false statement: "You're losing a lot of lives by keeping things closed."

The American Academy of Pediatrics has clarified its stance on school reopening amid the COVID-19 pandemic after the Trump administration repeatedly used the academy’s previous statement to pressure school systems to resume in-person learning in the fall.
The AAP, in a joint statement with three large education organizations, emphasized that school reopening should be driven by science and safety—“not politics.” It also directly responded to President Trump’s threat of withholding funding from schools that did not reopen, calling the move a “misguided approach.”
The point was echoed Monday by Michael Ryan, an infectious disease expert with the World Health Organization, who implored countries not to let school reopening become “yet another political football.”
The chief of Russia's space corporation, Dmitry Rogozin, offered less-than-flattering comments about NASA's Moon program in a recent interview with a Russian tabloid newspaper, Komsomolskaya Pravda.
Asked about Russia's interest in sending humans to the Moon and possibly partnering with NASA, Rogozin dismissed the Artemis program. He responded: "Frankly speaking, we are not interested in participating in such a project."
The Russian space chief has publicly complained for some time that NASA has chosen a 2024 landing date for political reasons. He has also compared US efforts to build a sustainable program of exploration on the surface of the Moon to American invasions of Afghanistan and Iraq.
Formula E only adopted its second-generation electric race car at the beginning of last season, but the motorsport is finalizing plans for the next iteration—called Gen3—set to debut in season nine (2022/2023). The plan is to make the car more powerful and lighter, with more ability to regenerate energy under braking. It will even adopt mid-race fast-charging. All of that is an improvement on the Gen2 car, but here at Ars, we can't help but feel that Formula E is missing an opportunity to be bolder. And we're not alone. Lucas di Grassi—season 3's champion—has his own idea for the direction Gen3 should take, and it's one the EV crowd will probably like.Formula E’s plan
Formula E's plan for the Gen3 car is evolutionary rather than revolutionary. Power is going up, with 350kW (469hp) available in qualifying, compared to the current 250kW (335hp), which will put speeds somewhere between Formula 3 and Formula 2. (Power output during the 45-minute races is capped at 300kW/402hp.) The battery is going to get considerably lighter, weighing 397lbs (180kg) compared to the current 547lbs (248kg), albeit with a slight reduction in capacity to 51kWh.
The battery will be able to charge at 600kW, more than twice the power of even the best EVs on sale today. That will enable mid-race fast charging, which will add 4kWh in 30 seconds. And the cars will be able to regenerate energy under deceleration at the same power level, thanks to a front-axle 250kW generator unit that works in conjunction with the 350kW motor-generator unit (MGU). However, the front wheels will only regenerate energy—there's no plan to allow the cars to deploy power to the front wheels, unlike just about every high-performance electric road car on sale or in development.
Hand axes are fairly common finds at sites dating between 2 million and 1 million years old. These sturdy tools have two sides (also called faces) and a sharp edge at one end. But hand axes are usually made of stone, so archaeologists working at the Konso Formation in southern Ethiopia were surprised to find a hand axe worked from a large chunk of bone buried in a 1.4 million-year-old layer of sediment. When Tohoku University archaeologist Katsuhiro Sano and his colleagues compared the bone to a collection of bone samples from large mammals, they found that their ancient hand axe had once been part of a hippopotamus femur (thigh bone).From hippopotamus to hand axe
The Konso find is only the second bone hand axe archaeologists have ever found, and one of just a handful of bone tools from sites older than 1 million years. Based on fossils found at Konso, the hominin who flaked off a chunk of hippo femur and worked it into a nice, sharp hand axe was probably a Homo erectus. Members of the species walked upright and were built a lot like modern humans, and they eventually spread from Africa, across Europe and Asia, and all the way to modern Indonesia.
At least one member of this species left behind a 13cm-long hand axe that is, according to Sano and his colleagues, an excellent piece of craftsmanship. The toolmaker apparently flaked a large, flattish piece of bone off the side of a hippo femur; you can still see the outer surface of the bone on one side of the hand axe. That fits the standard Acheulean approach to making hand axes and other tools; the first step is to make a large “blank” in the right general shape, then gradually flake off smaller pieces to shape the finished product.
Ramaswamy told Ars that the company's intention was to provide a secure and privacy-respecting platform from the start. But, he added—and we're paraphrasing here—"lawyers will be lawyers," and it was "on him" that he had not inspected the policies drafted by the company's legal counsel closely enough. He told us that he heard our readers' feedback loud and clear, and he pledged to overhaul the policy to bring it in line with the company's actual vision.
The gallery above displays the three areas in the policy that have changed since the call with Ars. Both references to third-party advertising—and tracking technologies associated with such advertising—have been entirely removed. The major impact here lies in expectations for third-party intrusions into the Neeva site itself, and it's an important one—there isn't much point in paying a monthly subscription in return for privacy if your search metadata might be leaking to the public giants you're trying to avoid in the first place.
Since its launch in 2016, the premise of mobile titan Pokémon Go has centered on roaming the outdoors in search of mystical little creatures. As a result, it’s a game that’s particularly ill-suited to pandemic-derived restrictions on movement.
In an attempt to remedy this, Pokémon Go developer Niantic has rolled out regular updates to make the game more quarantine-compatible in recent months. This has led to a new era of play among many in the Pokémon Go scene. Call it “stay-at-home, play-at-home.”
Such a systemic change in the way Pokémon Go is played was likely necessary for the game to survive in an era where many (if not most) players were unable or afraid to travel and gather together for their usual raids. By providing players with a way to play from home, Niantic is effectively removing the golden geese taunting them from the park across the road.
