An anonymous reader quotes a report from The New York Times: The mouse embryos looked perfectly normal. All their organs were developing as expected, along with their limbs and circulatory and nervous systems. Their tiny hearts were beating at a normal 170 beats per minute. But these embryos were not growing in a mother mouse. They were developed inside an artificial uterus, the first time such a feat has been accomplished, scientists reported on Wednesday. The experiments, at the Weizmann Institute of Science in Israel, were meant to help scientists understand how mammals develop and how gene mutations, nutrients and environmental conditions may affect the fetus. But the work may one day raise profound questions about whether other animals, even humans, should or could be cultured outside a living womb. In a study published in the journal Nature, Dr. Jacob Hanna described removing embryos from the uteruses of mice at five days of gestation and growing them for six more days in artificial wombs. At that point, the embryos were about halfway through their development; full gestation is about 20 days. A human at this stage of development would be called a fetus. To date, Dr. Hanna and his colleagues have grown more than 1,000 embryos in this way. But the research has already progressed beyond what the investigators described in the paper. In an interview, Dr. Hanna said he and his colleagues had taken fertilized eggs from the oviducts of female mice just after fertilization -- at Day 0 of development -- and had grown them in the artificial uterus for 11 days. [...] The artificial womb may allow researchers to learn more about why pregnancies end in miscarriages or why fertilized eggs fail to implant. It opens a new window onto how gene mutations or deletions affect fetal development. Researchers may be able to watch individual cells migrate to their ultimate destinations.

With the $1.9 trillion COVID relief bill signed into law, Senate Majority Leader Chuck Schumer (D-NY) is ready to tackle the next major challenge: President Joe Biden's call for a massive infrastructure bill. As part of that package, Schumer said he plans to include his ambitious proposal to get every American to swap their gas-guzzling car for an electric one. From a report: "It's a bold new plan designed to accelerate America's transition to all electric vehicles on the road, to developing a charging infrastructure, and to grow American jobs through clean manufacturing," Schumer told The Verge in a brief interview this week. "And the ultimate goal is to have every car manufactured in America be electric by 2030, and every car on the road be clean by 2040." The top-line details of the "cash for clunkers"-style plan haven't changed much since Schumer first proposed it in an op-ed in The New York Times in late 2019. But the political landscape has certainly shifted in favor of the Democrats, breathing new life into the idea. Under the proposal, anyone who trades in their gas car for an electric one would get a "substantial" point-of-sale discount, Schumer says. He wouldn't say how much of a discount, only that it would be "deep." A spokesperson later confirmed they are eyeing rebates that are "more generous" than the current $7,500 federal EV tax credit. He also wants to provide direct incentives to auto manufacturers to phase out their production of internal combustion engine vehicles and tax breaks for property owners to install EV chargers at their homes or apartment buildings. Lastly, he proposes to send direct subsidies to local governments to improve and expand the nation's network of EV charging stations. Schumer would deploy $45 billion in grants to upgrade the nation's charging infrastructure and $17 billion to encourage manufacturers to retrofit their facilities for EV production.

NASA is counting down to what should be the final major test of the massive rocket it is building to put the first woman and the next man on the moon. From a report: More than 700,000 gallons of supercold propellant will fill up the tanks of the 212-foot tall core stage so that it can fire its four engines without actually blasting off. The goal is to simulate what will happen during its first launch, a mission to send a capsule with no crew around the moon and back. That lunar mission is currently targeted for November, says NASA's acting administrator Steve Jurczyk, who notes that this rocket "is going to be the most powerful rocket ever developed." The window for the rocket test opens on Thursday, March 18, at 3 pm EDT, and the core stage of the rocket is set up at NASA's Stennis Space Center in Mississippi. In a firing test earlier this year, one of the rocket's engines had a failure that forced an early shutdown after only 67 seconds. "We can understand exactly what happened in the first test and what cut it short," says Jurczyk, who explains that one test parameter had been set too narrowly and that's now been fixed. "Start up on the first test went really well, and so we're reasonably confident we're going to have a good test this week." The test should last around eight minutes, to simulate the entire flight profile of this rocket stage, he explains, but the minimum of what they'd like to see is around 4 minutes. If all goes well, the rocket will move on to Kennedy Space Center in Florida, where the rest of the launch hardware is already waiting. Under the Trump administration, the agency had been aiming to get boots on the lunar surface by 2024, which would have been in a second term if the former president had been re-elected. That deadline was a goal that most in the space community felt was unrealistic. These days, NASA admits that there's no way to get people to the moon that quickly, given the recent appropriations given by Congress.

Abstract of a new paper posted on Nature: In recent years, there has been a great deal of concern about the proliferation of false and misleading news on social media. Academics and practitioners alike have asked why people share such misinformation, and sought solutions to reduce the sharing of misinformation. Here, we attempt to address both of these questions. First, we find that the veracity of headlines has little effect on sharing intentions, despite having a large effect on judgments of accuracy. This dissociation suggests that sharing does not necessarily indicate belief. Nonetheless, most participants say it is important to share only accurate news. To shed light on this apparent contradiction, we carried out four survey experiments and a field experiment on Twitter; the results show that subtly shifting attention to accuracy increases the quality of news that people subsequently share. Together with additional computational analyses, these findings indicate that people often share misinformation because their attention is focused on factors other than accuracy -- and therefore they fail to implement a strongly held preference for accurate sharing. Our results challenge the popular claim that people value partisanship over accuracy, and provide evidence for scalable attention-based interventions that social media platforms could easily implement to counter misinformation online.

Intel has hired Apple's former "I'm a Mac" actor Justin Long to create new ads praising PCs. From a report: Long starts each commercial with "Hello I'm a... Justin," with the typical white background you'd find on Apple's Mac vs. PC ads from the 2000s. Naturally, the ads focus on Mac vs. PC again, with Long mocking Apple's Touch Bar, lack of M1 multiple monitor support, and the "gray and grayer" color choices for a MacBook. One even goes all-in on Apple's lack of touchscreens in Macs or 2-in-1 support by mocking the fact you have to buy a tablet, keyboard, stylus, and even a dongle to match what's available on rival Intel-based laptops. Another ad also points out that "no one really games on a Mac." Intel has put out more ads where they point out that Mac doesn't have the gaming ecosystem that Windows laptops enjoy.

A whole list of countries -- including Germany, France, Italy, Spain, Sweden and Latvia -- have suspended dosing of the AstraZeneca/Oxford vaccine over reports of dangerous blood clots in some recipients. The company and international regulators say there is no evidence the shot is to blame, but that isn't stopping countries from taking action out of an abundance of caution. Derek Lowe, a medical chemist working in the pharmaceutical industry, explains what's going on with this vaccine: I think that there are several distinct levels to this problem. The first, obviously, is medical. The big question is, are the reports of vascular problems greater than one would expect in the vaccinated population as a whole? It's not clear to me what the answer is, and it may very well be "No, they aren't." That CNBC link above quotes Michael Head at Southampton as saying that the data so far look like the problems show up at at least the same levels, and may even be lower in the vaccinated group. AstraZeneca has said that they're aware of 15 events of deep vein thrombosis and 22 events pulmonary embolisms, but that's in 17 million people who have had at least one shot -- and they say that is indeed "much lower than would be expected to occur naturally in a general population of this size." It also appears to be similar to what's been seen with the other coronavirus vaccines, which rather than meaning "they're all bad" looks like they're all showing the same baseline signal of such events across a broad population, without adding to it. In that case, this could be an example of what I warned about back in December (and many others have warned about as well), the post hoc ergo propter hoc "false side effects" problem. I've been looking this morning, and so far have not found anyone clearly stating that the problems seen are running higher in the vaccinated patients [...]. I realize that there's a possibility (not a likely one, though) that some particular batch of vaccine is more problematic, but I haven't seen any solid evidence of that, either. The second half of the medical problem is naturally what happens when you suspend dosing of what is, in many cases in the EU, the only vaccine available. We've been seeing cases falling here in the US ever since a peak on the first week of January -- many of us were worried about what might have been a rise in February but which now just seems to have been a plateau, with cases continuing to drop since then. But many European countries are definitely seeing another wave of infections, and the EU case numbers as a whole are going in the opposite direction to the US ones. There are surely a lot of reasons for this, with new viral variants being one, slow vaccine rollouts being another, and now complete vaccination halts set to add even more. Put as bluntly as possible, even if the AZ/Oxford vaccine has these side effects (which again, I don't see any evidence for yet), you are still very likely to kill more people by not giving it. Lowe goes on to question what good the EMA and World Health Organization's recommendations and regulatory approvals are when one European country after another shuts down its use. He also brings up the third problem, which is public confidence. "The AZ/Oxford vaccine has been in trouble there since the day the first data came out," writes Lowe. "The efficacy numbers looked lower than the other vaccines that had reported by then, and as mentioned, the presentation of the data was really poorly handled and continued to be so for weeks. Now with these dosing suspensions, I have to wonder if this vaccine is ever going to lose the dark cloud it's currently sitting under..."

Teenage Twitter hacker Graham Ivan Clark has pleaded guilty to last summer's unprecedented bitcoin scam attack that involved the takeover of dozens of high-profile accounts on the social network, according to paperwork filed in Florida court on Tuesday. Clark, who was 17 when accused of leading the scam, will spend three years in prison as part of his plea deal. The Tampa Bay Times reported the news on Tuesday. From a report: Clark has already been credited with 229 days of time served since his arrest last summer. As part of the deal, Clark is also being sentenced as a "youthful offender," which lessened his prison time and also opens up the possibility that he can serve some of his sentence at a boot camp, according to the Tampa Bay Times. Clark will also be banned from using computers without permission and without supervision from law enforcement.

The online ad industry has been trying to stymie Apple's latest privacy enhancements by claiming they amount to an antitrust violation. However, early signs suggest the effort may be doomed. On Wednesday, the French Competition Authority refused to tell Apple to hold off implementing the changes, which will stop apps tracking iPhone and iPad users without their explicit consent, or force Apple to negotiate with app developers. From a report: The watchdog said what Apple was doing did not appear to be abusive, as "a company, even if it is in a dominant position ... has the freedom in principle to set rules to access its services, subject to not disregarding the laws and applicable regulations and that these rules are not anticompetitive." However, although the Competition Authority did not grant the "interim measures" that the Interactive Advertising Bureau (IAB) France and others had been seeking, it said it would continue investigating the merits of the case to see if Apple's new privacy rules allow the company itself to track users more than others can. Apple announced the contentious changes in June last year and was due to implement them in the fall, but complaints from Facebook and much of the ad industry led it to delay the move until early this year. Apple said in January that the changes would finally arrive in early spring. The iPhone maker attaches a unique code to each device, known as Identification for Advertisers, or IDFA. Advertisers can use this tag to monitor what users do in apps and how they interact with ad campaigns.

At a press conference today, the Japanese government said it was investigating the parent company behind the Line instant messaging app after a local newspaper reported that engineers at one of the app's Chinese contractors accessed the messages and personal details of Line users. From a report: According to Japanese newspaper The Asahi Shimbun, four Chinese engineers accessed Line's infrastructure and viewed messages and personal information of Line users, such as names, phone numbers, email addresses, and Line IDs. The four engineers worked for a yet-to-be-named Shanghai-based software firm that the LINE Corporation had subcontracted to develop artificial intelligence-based services for the Line application. The four engineers are said to have accessed Line user data on 32 different occasions since August 2018. Most of Line's 86 million userbase is made up of Japanese users, and the Asian country has very strict data and privacy protection regulations.

Regulators decided the next U.S. 5G airwaves auction will offer frequencies in portions covering millions of people, a plan backed by wireless giants thirsty for spectrum and opposed by cable providers leery of expensive bidding. From a report: The Federal Communications Commission with a 4-0 vote set rules for the sale that's to begin in October. It'll follow an airwaves auction that drew a record $81 billion in bids as companies race to establish next-generation ultrafast 5G wireless service. "We take action that will move us closer to 5G service that is fast, secure, reliable, and most importantly available everywhere in the country," FCC Acting Chairwoman Jessica Rosenworcel said as the agency voted at its monthly meeting in Washington.

A two-armed robot is helping to prepare soba noodles at an eatery at JR Kaihimmakuhari Station in this Chiba city's Mihama Ward (in Japan), capably boiling the noodles in a strainer, rinsing them and then dipping them in iced water. From a report: The Sobaichi Perie Kaihimmakuhari eatery implemented a collaborative cooking system, with the robot cooking the food and employees adding the dipping sauce or soup and toppings. It is apparently the first time for the cooking robot to be introduced in an actual restaurant setting. Soba stands at railway stations usually have to deal with a constant stream of customers and work under time pressure, resulting in a chronic shortage of human resources. [...] The robot fetches soba noodles from a box with one arm, and places it in a strainer. Then with the other arm, it picks up the strainer and boils the noodles for a minute and 40 seconds, rinses off the viscous film on the surface and then dips the noodles in iced water to bring out their firmness. The robot can cook 150 servings in an hour, substituting the work of about one employee.

A new feature has appeared at smoke shops in Montana, gas stations in the Carolinas and delis in far-flung corners of New York City: a brightly-lit bitcoin ATM, where customers can buy or sell digital currency, and sometimes extract hard cash. From a report: The machines have multiplied quickly through the United States over the past year, fueled by a frenzy in crypto trading that sent bitcoin prices over $58,000. Kiosk operators such as CoinFlip and Coin Cloud have installed thousands of ATMs, scouring areas competitors have not yet reached, executives told Reuters. "I just assumed there was demand and people wanted bitcoin everywhere," said Quad Coin founder Mark Shoiket, who flew to Montana after scanning a U.S. map for bitcoin ATM deserts. During a week-long road trip, he found seven places to install machines, including 406 Glass, a store in Billings, Montana, that sells tobacco, vape juice and colorful glass pipes. As of January, there were 28,185 bitcoin ATMs in the United States, according to howmanybitcoinatms.com, an independent research site. Roughly 10,000 came within the prior five months.

The U.S. Federal Communications Commission moved toward barring China Unicom (Hong Kong) and ComNet from the U.S., calling the Chinese telecommunications carriers a security risk controlled by the Beijing government. From a report: The action against two of China's three major telecommunications operators was decided by a 4-0 vote by agency. It continues a security crackdown that earlier touched Chinese gear makers Huawei Technologies and ZTE. In 2019, the FCC barred China Mobile Ltd. from the U.S. market over national security concerns. ComNet, a subsidiary of Pacific Networks, and the unit formally known as China Unicom (Americas) Operations Ltd. were told in April by the FCC to show they are independent from the Chinese government, or face a proceeding that could result in ejection from the U.S. market. With its vote Wednesday the FCC began those proceedings. China Unicom and Pacific Networks are indirectly and ultimately owned and controlled by the government of the People's Republic of China, the FCC said in news releases Wednesday. The companies may present evidence in proceedings set in motion, according to the news releases.
