NASA kills lunar space station to focus on ambitious Moon base

NASA kills lunar space station to focus on ambitious Moon base

WASHINGTON, DC—NASA Administrator Jared Isaacman on Tuesday laid out a sweeping vision for the space agency’s next decade during an event called “Ignition” in which he and other senior leaders set out their exploration plans.

Isaacman and his colleagues shared a number of major announcements, including outlining a nuclear-powered mission to Mars that will release three helicopters there and major changes to commercial space stations. However, most significantly, Isaacman outlined a detailed plan to construct a substantial Moon base over the next decade. He framed it as part of a "great power" challenge, saying that if NASA does not succeed now it will cede the Moon to China.

The base included long-range drones, multiple sources of power, sophisticated communications, permanent habitats, scientific laboratories, local manufacturing, and more. To accomplish this, NASA will work with a broad range of industry partners capable of sending medium-size and large cargos to the lunar surface. Isaacman also confirmed that NASA will no longer build a Lunar Gateway in orbit around the Moon, but would rather focus all of its energy and resources on the lunar surface.

A mission NASA might kill is still returning fascinating science from Jupiter

A mission NASA might kill is still returning fascinating science from Jupiter

Jupiter's colossal storms generate lightning flashes at least 100 times more powerful than those on Earth, according to scientists analyzing data from NASA's Juno spacecraft.

The findings were published March 20 in the journal AGU Advances and were based on data recorded by Juno in 2021 and 2022, after NASA granted an extension to the spacecraft's operations upon completing a five-year science campaign at Jupiter. Juno remains in good health, but NASA officials have not said if they will approve another extension for the mission. The issue is money.

Questions about the future of Juno and more than a dozen other robotic science missions began swirling nearly a year ago, when the Trump administration asked mission leaders to submit "closeout" plans for how to turn off their spacecraft. Ars first reported the news soon after the White House released a budget request that called for slashing NASA's science budget by nearly half.

Trump's MAHA pick for surgeon general flounders amid GOP doubts

Trump's MAHA pick for surgeon general flounders amid GOP doubts

President Trump's pick for surgeon general, Casey Means, is in jeopardy, as at least four Republican senators have expressed misgivings over her medical qualifications, views on vaccines, and some dubious advice she's given as a wellness influencer, according to reporting from The Washington Post.

Senators Bill Cassidy (R-La.), Susan Collins (R-Maine), Lisa Murkowski (R-Alaska), and Thom Tillis (R-N.C.) all expressed concern in a confirmation hearing last month about her potential role and appear to remain doubtful. Just one of those senators may be enough to block her nomination from advancing beyond the Senate Health Committee.

Means, who was nominated more than 10 months ago, is known as a prominent wellness influencer within the Make America Healthy Again movement and a close ally of anti-vaccine Health Secretary Robert F. Kennedy Jr., who started it. In the hearing, senators pressed Means on her views on vaccines, including shots against the flu and measles and a dose of hepatitis B vaccine for newborns. She largely dodged the questions, refusing to explicitly recommend the life-saving shots, and avoided overtly contradicting Kennedy's anti-vaccine views and misinformation.

After hackers hit an Iowa company, cars around the country failed to start

After hackers hit an Iowa company, cars around the country failed to start

Driving after a DUI conviction can be a dicey experience. Many states require drivers, if they want to keep using their cars, to install ignition interlock devices that measure alcohol levels before allowing the vehicle to start.

One of the most common is from Des Moines, Iowa-based Intoxalock, which takes the form of a small box with a plastic tube into which the driver blows. The box then measures the level of alcohol in the breath. You must be below your state's legal limit to start the vehicle. (In some states, the system will also log your location using GPS and/or take a photo of you every time you blow in the tube.)

The interlock device can only be leased, and it costs around $70–$120 per month.

LG Display starts mass-producing LTPO-like 1 Hz LCD displays for laptops

LG Display starts mass-producing LTPO-like 1 Hz LCD displays for laptops

LG Display is mass-producing laptop screens that automatically change their refresh rate from 1 Hz to up to 120 Hz, based on what’s on-screen, it announced this week. The display supplier said that it’s the first company to mass-produce these 1–120 Hz screens, which are supposed to boost battery life.

According to LG’s announcement, the LCD screens, which it’s calling Oxide 1Hz, will automatically use a 1 Hz refresh rate when detecting a static image on-screen and switch to up to 120 Hz when needed. Without providing more detail, LG said it created proprietary “circuit algorithms and panel design technology” and discovered “new materials and [applies] the oxide with the lowest power leakage during low-refresh-rate mode to the display’s thin-film transistor.”

In its announcement this week, LG said that “when performing tasks involving primarily still images—such as checking emails or reading e-books and research papers—the panel operates at the lowest refresh rate of 1 Hz. Conversely, it runs in high-refresh-rate mode at up to 120 Hz when streaming content such as movies or sports as well as playing games with frequent screen changes.

Intuit beats FTC in court, ending restrictions on "free" TurboTax ads

Intuit beats FTC in court, ending restrictions on "free" TurboTax ads

An appeals court invalidated the Biden-era Federal Trade Commission's attempt to punish Intuit for allegedly deceptive ads that pitched TurboTax as free.

Under then-Chair Lina Khan, the FTC determined in 2024 that the TurboTax maker violated US law with deceptive advertising and ordered it to stop telling consumers, without more obvious disclaimers, that TurboTax or other products are free. The FTC’s chief administrative law judge had previously found that Intuit's ads violated prohibitions on deceptive advertising because the firm “advertised to consumers that they could file their taxes online for free using TurboTax, when in truth, for approximately two-thirds of taxpayers, the advertised claim was false."

Intuit appealed in the conservative-leaning US Court of Appeals for the 5th Circuit and got a resounding victory on Friday in a 3–0 ruling issued by a panel of judges. "Following the Supreme Court’s decision in SEC v. Jarkesy, we hold that adjudication of a deceptive advertising claim before an administrative law judge violated the constitutional separation of powers," the 5th Circuit panel said.

AI is beginning to change the business of law

AI is beginning to change the business of law

In spring 2024, two days after undergoing complex cardiac surgery in the Midlands, a man in his mid-70s unexpectedly deteriorated and died.

The hospital referred the death to the coroner’s service, as is protocol when a cause is unknown, and clinical negligence barrister Anthony Searle was instructed by the man’s devastated family to represent them.

To try to get to the bottom of what had happened, Searle knew he would need to ask the surgeons some probing questions. So when the coroner declined his request for an independent expert report, Searle was frustrated.
