The Most Precise-Ever Measurement of W Boson Mass Suggests the Standard Model Needs Improvement

After 10 years of careful analysis and scrutiny, scientists of the CDF collaboration at the U.S. Department of Energy’s Fermi National Accelerator Laboratory announced today that they have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles. Phys.Org reports: Using data collected by the Collider Detector at Fermilab, or CDF, scientists have now determined the particle’s mass with a precision of 0.01% — twice as precise as the previous best measurement. It corresponds to measuring the weight of an 800-pound gorilla to 1.5 ounces. The new precision measurement, published in the journal Science, allows scientists to test the standard model of particle physics, the theoretical framework that describes nature at its most fundamental level. The result: The new mass value shows tension with the value scientists obtain using experimental and theoretical inputs in the context of the standard model. If confirmed, this measurement suggests the potential need for improvements to the standard model calculation or extensions to the model.

‘We Probably Pissed Away $200 Million,’ Better.com CEO Told Employees In Layoffs Meeting

When Better.com CEO Vishal Garg laid off 900 employees, or about 9% of the company’s staff, in early December, the startup world was shocked with his callous delivery. Now a video of Garg and CFO Kevin Ryan addressing the remaining employees right after the chief executive performed those layoffs has emerged, confirming many reports of his brash style and harsh words about those affected. TechCrunch reports: In a video obtained by TechCrunch, Garg is seen addressing the layoffs and in the process, admitting to making a number of mistakes. We chose not to publish the video in an effort to protect the identity of the source, but we’ve picked out the most relevant bits based on a transcription of the 12-minute meeting. About two minutes into the meeting, Garg says: “Make no mistake we did also eliminate redundant roles — who might be strong performers but were in the wrong place at the wrong time, with the wrong task, and weren’t mission critical.”

After about four minutes, Garg also acknowledged that the company was continuing to hire, including some interns, in the midst of the layoffs, while at the time making a thinly veiled threat: “…It’s because we expect those people to be super productive and add value, and if they don’t we will exit them too.” He added: “We are going to be leaner, meaner and hungrier going forward. We will not be spending time trying to raise capital. We will not be spending time focused on what investors think. We will be spending time grinding this business forward in what will likely be a bloodbath in the mortgage industry in the next year or two.”

In the video at around the 8-minute mark, Garg admits to not being disciplined in managing the company’s cash and in its hiring strategy, which helps explain the company’s second mass layoff of over 3,000 people just three months later. It also helps support multiple sources’ claims that the company is currently “losing $50 million per month.” “Today we acknowledge that we overhired, and hired the wrong people. And in doing that we failed. I failed. I was not disciplined over the past 18 months. We made $250 million last year, and you know what, we probably pissed away $200 million. We probably could have made more money last year and been leaner, meaner and hungrier.” He also explicitly says that the company lost $100 million in the previous quarter, saying it was his “mistake” for not laying off staff earlier.

Police Records Show Women Are Stalked With Apple AirTags Across the Country

samleecole shares a report from Motherboard: Police records reviewed by Motherboard show that, as security experts immediately predicted when the product launched, this technology has been used as a tool to stalk and harass women. Motherboard requested records mentioning AirTags in a recent eight month period from dozens of the country’s largest police departments. We obtained records from eight police departments. Of the 150 total police reports mentioning AirTags, in 50 cases women called the police because they started getting notifications that their whereabouts were being tracked by an AirTag they didn’t own. Of those, 25 could identify a man in their lives — ex-partners, husbands, bosses — who they strongly suspected planted the AirTags on their cars in order to follow and harass them. Those women reported that current and former intimate partners — the most likely people to harm women overall — are using AirTags to stalk and harass them.

Multiple women who filed these reports said they feared physical violence. One woman called the police because a man she had a protective order against was harassing her with phone calls. She’d gotten notifications that an AirTag was tracking her, and could hear it chiming in her car, but couldn’t find it. When the cops arrived, she answered one of his calls in front of the officer, and the man described how he would physically harm her. Another who found an AirTag in her car had been wondering how a man she had an order of protection against seemed to always know where she was. The report said she was afraid he would assault or kill her. […] The overwhelming number of reports came from women. Only one case out of the 150 we reviewed involved a man who suspected an ex-girlfriend of tracking him with an AirTag.

MIT Grad Students Vote To Form Labor Union

Graduate students at the Massachusetts Institute of Technology overwhelmingly approved forming a union in a two-day vote this week by a nearly 2-to-1 margin. From a report: MIT is the latest Boston-area school where grad students have voted to join a union following pivotal federal ruling in 2016 recognizing grad students as employees with the ability to unionize. In all, 1,785 MIT graduate students voted in favor of unionization and 912 against, a figure confirmed by Jonathan Zong, a grad student organizer, and MIT. Three-fourths of graduate students voted, according to MIT. The vote seeks to join United Electrical, Radio & Machine Workers of America, or UE. MIT grad students were pushing for help with affordable housing, support for international students, dental insurance coverage, and a better emphasis on diversity, equity and inclusion.

“We are grateful to the many members of our community, on all sides of the debate, who have engaged constructively and respectfully in this conversation,” Melissa Nobles, the chancellor, and Ian A. Waitz, the vice chancellor, said in the message to grad students. The memo continued: “Indeed, as we wrote to you during this campaign: We agree that there are areas where MIT can improve, and we share many of the same goals as the MIT Graduate Student Union. … With the election outcome now clear, we will continue to work alongside you to improve MIT for all of our students.” MIT’s Zong said being unionized will be a more democratic and formalized way of making grad students’ concerns heard compared to MIT’s Graduate Student Council. He described the council as more advisory to the school’s administration.

Canada Considers Law Requiring Online Giants To Compensate News Outlets

The federal Liberal government introduced legislation Tuesday to force digital giants to compensate news publishers for the use of their content. CBC News reports: The new regulatory regime would require companies like Google and the Meta Platforms-owned Facebook — and other major online platforms that reproduce or facilitate access to news content — to either pay up or go through a binding arbitration process led by an arms-length regulator, the Canadian Radio-television and Telecommunications Commission (CRTC). The compensation extracted from these digital giants must be used, in large part, to fund the creation of news content to protect the “sustainability of the Canadian news ecosystem,” according to a government backgrounder distributed to reporters. The government is pitching the arrangement as a way to prop up an industry that has seen a steady decline since the emergence of the internet.

To preserve access to Canadian news, the federal government has adopted much of the so-called “Australian model,” named after the country that first forced digital companies to pay for the use of news content. According to the Australian Competition and Consumer Commission, more than $190 million has been paid already to Australian media companies since the model was enacted last year. The big winners have been legacy media and larger media outlets.

The new Canadian scheme would require that Facebook, Google and other digital platforms that have “a bargaining imbalance with news businesses” make “fair commercial deals” with newspapers, news magazines, online news businesses, private and public broadcasters and certain non-Canadian news media that meet specific criteria. The goal is to have these digital platforms negotiate deals with publishers without the need for government intervention. [T]he amount of money each news business gets from these digital giants will be decided by those negotiations — there’s no preset formula. In the absence of some sort of voluntary arrangement, news businesses can initiate a mandatory bargaining process and go to a CRTC arbitration panel for a binding decision.

7,000 Steps Can Save Your Life

Mortality risk was reduced by 50% for older adults who increased their daily steps from around 3,000 to around 7,000, according to new medical research. Axios reports: 7,000 is the new 10,000, in terms of steps you should shoot for, The Lancet medical journal reports. This is all it takes for those 60 and older to dramatically increase their lifespans. Even for younger adults, the benefits of daily walking actually level off around 9,000 steps per day, not 10,000, the researchers found. The risk reduction plateaued beyond that number.

“Walking benefits nearly every cell in the body,” says Amanda Paluch, a kinesiologist and public health expert at UMass Amherst and the lead author of the study. It’s wildly effective. Walking strengthens your heart, improves bone density, relaxes your mind, and helps with muscle-building and pain management. Almost everyone can do it anywhere: your house, the office, outside. Start with 30 minutes and work your way up.”It’s not an all or nothing situation,” says Paluch. Even just boosting daily step count to 5,000 — for 60 and older — and 7,000 — for younger folks — slashed mortality risk by 40%.

EU Clears First Autonomous X-Ray-Analyzing AI

An artificial intelligence tool that reads chest X-rays without oversight from a radiologist got regulatory clearance in the European Union last week — a first for a fully autonomous medical imaging AI, the company, called Oxipit, said in a statement. The Verge reports: The tool, called ChestLink, scans chest X-rays and automatically sends patient reports on those that it sees as totally healthy, with no abnormalities. Any images that the tool flags as having a potential problem are sent to a radiologist for review. Most X-rays in primary care don’t have any problems, so automating the process for those scans could cut down on radiologists’ workloads, the Oxipit said in informational materials.

The tech now has a CE mark certification in the EU, which signals that a device meets safety standards. The certification is similar to Food and Drug Administration (FDA) clearance in the United States, but they have slightly different metrics: a CE mark is less difficult to obtain, is quicker, and doesn’t require as much evaluation as an FDA clearance. The FDA looks to see if a device is safe and effective and tends to ask for more information from device makers. Oxipit spokesperson Mantas Miksys told The Verge that the company plans to file with the FDA as well.

Oxipit said in a statement that ChestLink made zero “clinically relevant” errors during pilot programs at multiple locations. When it is introduced into a new setting, the company said there should first be an audit of existing imaging programs. Then, the tool should be used under supervision for a period of time before it starts working autonomously. The company said in a statement that it expects the first healthcare organizations to be using the autonomous tool by 2023.

The US Government Has Just 1% of the EV Chargers It Needs

An anonymous reader quotes a report from TechCrunch: The U.S. government owns about 1,100 charging stations. It may need more than 100,000 charging stations to support widespread EV use in the next decade, according to testimony from the Government Accountability Office (GAO) on Tuesday. The testimony, which was first reported by Reuters, mainly delved into the U.S. Postal Service’s efforts to transition its fleet to EVs and federal fleet transition issues. GAO found that federal agencies like USPS held certain incorrect assumptions about the cost and benefits of using gas versus electric vehicles, namely that USPS used gas prices that are about $2 per gallon less than the current national average in its estimates, and assumed maintenance and acquisition costs that are higher than the reality.

GAO has identified charging infrastructure costs and installation as a key challenge to acquiring EVs for federal fleets. […] The General Services Administration (GSA) said that as of March 10, federal agencies have only ordered an additional 1,854 zero-emission vehicles since its prior report. The U.S. government usually purchases about 50,000 vehicles annually. The federal fleet currently has about 657,000 cars, SUVs and trucks, out of which less than 1% are currently electric, according to GSA data.

Microsoft Brings Arm Support To Azure Virtual Machines

It’s been a long road, but Microsoft announced on April 4 a preview of Arm support on Azure virtual machines via its work with Ampere Computing. ZDNet reports: Ampere is a startup that makes server chips. Ampere announced last year it had signed up Microsoft and Tencent Holdings as major customers. “We are now supporting Arm on Azure as well. This has been a long journey to bring up Ampere on Azure with Windows as the Root Host OS! we are also supporting Windows 11 Arm VMs in preview for developers!” tweeted Hari Pulapaka, the director of PM for Azure Host OS and the Windows OS platform. “FYI all Windows developers who have been asking for VM support in Azure, it’s here now.”

Azure VMs with Ampere Altra Arm-based processors will offer up to 50 percent better price-performance than comparable x86-based VMs for scale-out workloads, Microsoft officials said. These new VMs are also for Web servers, application servers, open-source databases, gaming servers, media servers, and more, they added. The preview is initially available in the West US 2, West Central US, and West Europe Azure regions. Ampere’s announcement of the Azure VM preview is here.

Trump’s Truth Social App Branded a Disaster

Donald Trump’s Truth Social has “been a disaster,” says Joshua Tucker, director of NYU’s Center for Social Media and Politics. According to the BBC, “The app launched on Presidents’ Day, 21 February, but six weeks later is beset by problems. A waiting list of nearly 1.5 million are unable to use it.” From the report: Truth Social might look like Twitter, but it isn’t available on Android phones, web browsers or, apparently, to most people outside the US. And a Republican ally of Mr Trump’s, who did not wish to be identified, said: “Nobody seems to know what’s going on.” On 21 February, Truth Social was one of the App Store’s most downloaded apps — but many who downloaded it were unable to use it. There was an assumption this problem would soon be resolved and Mr Trump would start posting his “truths” in the coming days — but neither of those things happened. My attempt to register, this week, was placed at number 1,419,631 on the waiting list.

While YouTube, TikTok, Instagram and Facebook are among the 10 most downloaded apps, according to Similar Web, Truth Social is outside the top 100. Users who find their way in can find the app a little empty, as many big voices on the American right have so far stayed away. Another study found downloads have fallen by as much as 95%. And many are feeling frustrated. “Signed up for Truth Social a couple weeks ago and still on a waiting list,” one Twitter user said, on Tuesday. “By the time I’m off the waiting list and on to Truth Social for real, Trump will be President again,” joked another. The report says Mr Trump “has not posted a ‘truth’ for well over a month.”

“Maybe they’re holding him back,” Mr Tucker said. “That’s his last chance to launch it – when suddenly Trump comes in and starts being really active on it, that will get a buzz.”
