On April 2, 2025, our president announced major new taxes on imports from foreign countries (“tariffs”), ranging from 10 percent to 49 percent. The stated goal is to bring manufacturing back to the United States and to “make America wealthy again.”

These tariffs will not work. In fact, they may even do the opposite, fail to bring manufacturing back, and make America poorer in the process.

This article gives the 14 reasons why this is the case, how the United States could bring manufacturing back if it were serious about doing so, and what will ultimately happen with this wrongheaded policy.

A government whistleblower told lawmakers that DOGE's access to National Labor Relations Board (NLRB) systems went far beyond what was needed to analyze agency operations and apparently led to a data breach. NLRB employee Daniel Berulis, a DevSecOps architect, also says he received a threat when he was preparing his whistleblower disclosure.

"Mr. Berulis is coming forward today because of his concern that recent activity by members of the Department of Government Efficiency ('DOGE') have resulted in a significant cybersecurity breach that likely has and continues to expose our government to foreign intelligence and our nation's adversaries," said a letter from the group Whistleblower Aid to the Senate Select Committee on Intelligence leaders and the US Office of Special Counsel.

The letter, Berulis' sworn declaration, and an exhibit with screenshots of technical data are available here . "This declaration details DOGE activity within NLRB, the exfiltration of data from NLRB systems, and—concerningly—near real-time access by users in Russia," Whistleblower Aid Chief Legal Counsel Andrew Bakaj wrote. "Notably, within minutes of DOGE personnel creating user accounts in NLRB systems, on multiple occasions someone or something within Russia attempted to login using all of the valid credentials (e.g. Usernames/Passwords). This, combined with verifiable data being systematically exfiltrated to unknown servers within the continental United States—and perhaps abroad—merits investigation."

Several years ago, Harvard University roboticist Robert Wood made headlines when his lab constructed RoboBee , a tiny robot capable of partially untethered flight. Over the years, RoboBee has learned to fly, dive, and hover. The latest improvement: RoboBee has learned how to stick the landing, thanks to biomechanical improvements to its landing gear modeled on the crane fly, which has a similar wingspan and body size to the RoboBee platform. The details of this achievement appear in a new paper published in the journal Science Robotics.

As previously reported , the ultimate goal of the RoboBee initiative is to build a swarm of tiny interconnected robots capable of sustained untethered flight—a significant technological challenge, given the insect-sized scale, which changes the various forces at play. In 2019, Wood's group announced its achievement of the lightest insect-scale robot so far to have achieved sustained, untethered flight—an improved version called the RoboBee X-Wing. In 2021, Wood's group turned its attention to the biomechanics of the mantis shrimp's knock-out punch and built a tiny robot to mimic that movement

But RoboBee was not forgotten, with the team focusing this time around on achieving more robust landings. “Previously, if we were to go in for a landing, we’d turn off the vehicle a little bit above the ground and just drop it, and pray that it will land upright and safely,” said co-author Christian Chan , one of Wood's graduate students. The trick is to minimize velocity when approaching a surface and then quickly dissipating impact energy. Even something as small and light as RoboBee can generate significant impact energy. The crane fly has long, jointed appendages that enable them to dampen their landings, so the insect served as a useful model for RoboBee's new landing gear.

MIAMI—A decade after its first visit to the state , Formula E returned to Florida this past weekend. The even has come a long way since that first chaotic Miami ePrix: The cars are properly fast now, the racing is both entertaining and quite technical, and at least the trackside advertising banners were in place before the start of the event this time.

It's not the same track, of course. Nor is it anywhere near the Hard Rock Stadium that Formula 1 now fills with ersatz marinas and high-priced hospitality packages during its visit to the area. Despite what the b-roll helicopter shots might have led viewers to believe, we were actually an hour south of the city at a mid-sized oval track next to a landfill in Homestead. Usually, a place that hosts NASCAR races, for Formula E, there was a 2.2-mile (3.5 km) layout that used the straights and infield but not the banked corners.

Formula E has begun to branch out from its original diet of racing exclusively on temporary city center street tracks, having visited Portland International Raceway in Oregon in 2023 and 2024 . Despite the bucolic charm of PIR, with its easy bicycle and light rail access, enthusiastic crowd of attendees, and exciting racing, it was only a temporary patch for Formula E. The vast majority of Formula E's fans live outside the US, and Portland means nothing to them, but they've heard of Miami, I was told last year.

In now-rarified comments from experts at the Centers for Disease Control and Prevention, an agency official on Tuesday evening said the explosive measles outbreak mushrooming out of West Texas will require "significant financial resources" to control and that the agency is already struggling to keep up.

"We are scrapping to find the resources and personnel needed to provide support to Texas and other jurisdictions," said David Sugerman, the CDC's lead on its measles team. The agency has been devastated by brutal cuts to CDC staff and funding, including a clawback of more than $11 billion in public health funds that largely went to state health departments.

Sugerman noted that the response to measles outbreaks is generally expensive. "The estimates are that each measles cases can be $30,000 to $50,000 for public health response work—and that adds up quite quickly." The costs go to various responses, including on-the-ground response teams, vaccine doses and vaccination clinics, case reporting, contact tracing, mitigation plans, infection prevention, data systems, and other technical assistance to state health departments.

Google may have finally found an application of large language models (LLMs) that even AI skeptics can get behind. The company just released its 2024 Ads Safety report, confirming that it used a collection of newly upgraded AI models to scan for bad ads. The result is a huge increase in suspended spammer and scammer accounts, with fewer malicious ads in front of your eyeballs.

While stressing that it was not asleep at the switch in past years, Google reports that it deployed more than 50 enhanced LLMs to help enforce its ad policy in 2024. Some 97 percent of Google's advertising enforcement involved these AI models, which reportedly require even less data to make a determination. Therefore, it's feasible to tackle rapidly evolving scam tactics.

Google says that its efforts in 2024 resulted in 39.2 million US ad accounts being suspended for fraudulent activities. That's over three times more than the number of suspended accounts in 2023 (12.7 million). The factors that trigger a suspension usually include ad network abuse, improper use of personalization data, false medical claims, trademark infringement, or a mix of violations.

The semiconductor industry is bracing to potentially lose more than $1 billion once Donald Trump announces chip tariffs.

Two sources familiar with discussions between chipmakers and lawmakers last week told Reuters that Applied Materials, Lam Research, and KLA—three of the largest US chip equipment makers—could each lose about "$350 million over a year related to the tariffs." That adds up to likely more than $1 billion in losses between the three, and smaller firms will likely face similarly spiked costs, estimating losses in the tens of millions.

Some chipmakers are already feeling the pain of Trump's trade war, despite a 90-day pause on reciprocal tariffs and a tenuous exception for semiconductors and other electronics.

The Common Vulnerability and Exposures, or CVE , repository holds the answers to some of information security's most vital questions. Namely, which security issue are we talking about, exactly, and how does it work?

The 25-year-old CVE program, an essential part of global cybersecurity, is cited in nearly any discussion or response to a computer security issue, including Ars posts. CVE was at real risk of closure after its contract was set to expire on April 16. The nonprofit MITRE runs CVE and related programs (like Common Weakness Enumeration, or CWE) on a contract with the US Department of Homeland Security (DHS). A letter to CVE board members sent Tuesday by Yosry Barsoum, vice president of MITRE, gave notice of the potential halt to operations.

"If a break in service were to occur, we anticipate multiple impacts to CVE, including deterioration of national vulnerability databases and advisories, tool vendors, incident response operations, and all manner of critical infrastructure," Barsoum wrote.

A New Mexico man is facing federal charges for two separate incidents of alleged arson—one at an Albuquerque Tesla showroom and one at the New Mexico Republican Party’s office—according to a Monday press release from the Department of Justice.

Jamison Wagner, 40, was charged with allegedly setting fire to a building or vehicle used in interstate commerce. The charge can apply to goods manufactured and sold in different states and the facilities that house them—like the Tesla showroom or the Republican office, which also sells MAGA merchandise. DOJ spokesperson Shannon Shevlin tells WIRED that Wagner’s arrest happened on Saturday.

“Let this be the final lesson to those taking part in this ongoing wave of political violence,” Attorney General Pam Bondi said in the Monday press release. “We will arrest you, we will prosecute you, and we will not negotiate. Crimes have consequences.”
