As Google moves the last remaining Nest devices into the Home app, it's also looking at ways to make this smart home hub easier to use. Naturally, Google is doing that by ramping up Gemini integration. The company has announced new automation capabilities with generative AI, as well as better support for third-party devices via the Home API. Google AI will also plug into a new Android widget that can keep you updated on what the smart parts of your home are up to.

The Google Home app is where you interact with all of Google's smart home gadgets, like cameras, thermostats, and smoke detectors—some of which have been discontinued, but that's another story . It also accommodates smart home devices from other companies, which can make managing a mixed setup feasible if not exactly intuitive. A dash of AI might actually help here.

Google began testing Gemini integrations in Home last year, and now it's opening that up to third-party devices via the Home API. Google has worked with a few partners on API integrations before general availability. The previously announced First Alert smoke/carbon monoxide detector and Yale smart lock that are replacing Google's Nest devices are among the first, along with Cync lighting, Motorola Tags, and iRobot vacuums.

NASA's Apollo missions brought back moon rock samples for scientists to study. We've learned a great deal over the ensuing decades, but one enduring mystery remains. Many of those lunar samples show signs of exposure to strong magnetic fields comparable to Earth's, yet the Moon doesn't have such a field today. So, how did the moon rocks get their magnetism?

There have been many attempts to explain this anomaly. The latest comes from MIT scientists, who argue in a new paper published in the journal Science Advances that a large asteroid impact briefly boosted the Moon's early weak magnetic field—and that this spike is what is recorded in some lunar samples.

Evidence gleaned from orbiting spacecraft observations, as well as results announced earlier this year from China's Chang'e 5 and Chang'e 6 missions, is largely consistent with the existence of at least a weak magnetic field on the early Moon. But where did this field come from? These usually form in planetary bodies as a result of a dynamo, in which molten metals in the core start to convect thanks to slowly dissipating heat. The problem is that the early Moon's small core had a mantle that wasn't much cooler than its core, so there would not have been significant convection to produce a sufficiently strong dynamo.

On Tuesday, Google launched Veo 3 , a new AI video synthesis model that can do something no major AI video generator has been able to do before: create a synchronized audio track. While from 2022 to 2024, we saw early steps in AI video generation, each video was silent and usually very short in duration. Now you can hear voices, dialog, and sound effects in eight-second high-definition video clips.

Shortly after the new launch, people began asking the most obvious benchmarking question: How good is Veo 3 at faking Oscar-winning actor Will Smith at eating spaghetti?

First, a brief recap. The spaghetti benchmark in AI video traces its origins back to March 2023, when we first covered an early example of horrific AI-generated video using an open source video synthesis model called ModelScope. The spaghetti example later became well-known enough that Smith parodied it almost a year later in February 2024.

Is it weird to have nostalgia for an operating system? I don't mean missing a particular feature that's been removed from modern versions or a specific productivity setting that's no longer supported. I mean a sense of longing for the vibes of the computer interface you grew up with, an ache for the aesthetics of user interfaces past.

I would have thought I was immune to this particular brand of nostalgia. Then I happened upon Desktop Survivors 98 , a new Vampire Survivors -style "bullet heaven" autoshooter that leans hard into the aesthetics of the late '90s Windows machines I grew up with. And while that low-res, 256-color presentation is what drew me in, it was the intriguing mouse-controlled gameplay underneath that has kept me coming back for more retro-styled action all week.

Start me up

When it comes to capturing the feel of the '90s computer environment, Desktop Survivors 98 gets everything just right. This is in large part due to rampant theft of familiar old-school icons; items like My Computer, Calculator, Minesweeper, Search, and more look like they were taken directly from a classic Microsoft tile set. The game's low-res desktop backgrounds and Windows also look like they came out of a years-old Microsoft style book.

Amid the brutal cuts across the federal government under the Trump administration, perhaps one of the most gutting is the loss of experts at the Centers for Disease Control and Prevention who respond to lead poisoning in children.

On April 1, the staff of the CDC's Childhood Lead Poisoning Prevention Program was terminated as part of the agency's reduction in force, according to NPR . The staff included epidemiologists, statisticians, and advisors who specialized in lead exposures and responses.

The cuts were immediately consequential to health officials in Milwaukee, who are currently dealing with a lead exposure crisis in public schools. Six schools have had to close, displacing 1,800 students. In April, the city requested help from the CDC's lead experts , but the request was denied—there was no one left to help.

In the US, many newly constructed generating facilities are brought online at the end of the year to qualify for tax incentives. Since much of the US's new generating capacity is solar power, that has led to a boom in solar production to start the year in recent years. With the first three months of data in for 2025, it's clear this year is no exception: Solar power is up a staggering 44 percent compared to the prior year.

That's the good news. The bad news is that, in contrast to China , solar's growth hasn't been enough to offset rising demand. Instead, the US also saw significant growth in coal use, which rose by 23 percent compared to the year prior, after years of steady decline.

Short-term fluctuations in demand are normal, generally driven by weather-induced demand for heating or cooling. Despite those changes, demand for electricity in the US has been largely flat for over a decade, largely thanks to gains in efficiency. But 2024 saw demand go up by nearly three percent, and the first quarter of 2025 saw another rise, this time of nearly five percent. It's a bit too early to say that we're seeing a shift to a period of rising demand, but one has been predicted for some time due to rising data center use and the increased electrification of transportation and appliances.

Valve is releasing version 3.7 of SteamOS to the general public , and among the routine updates and changes is a big one: This is the SteamOS release that finally adds official support for some kinds of PC hardware other than Valve's own Steam Deck.

Valve mentions certain specific handhelds as having either "official" or "improved support," including the Asus ROG Ally, the Lenovo Legion Go, and the Lenovo Legion Go S. It also includes directions for configuring the original Legion Go and ROG Ally for SteamOS installation. But Valve says that only the Steam Deck and Legion Go S have fully baked SteamOS support.

The release claims to run on "other AMD powered handhelds" more broadly, implying that most third-party handheld PCs with Ryzen Z1 or Z2-series processors ought to support at least some basic functionality. Other all-AMD desktops and laptops have a decent shot at being supported, too.

Expert advisors for the Food and Drug Administration met Thursday to discuss which virus strain this year's updated COVID-19 vaccines should target. The advisors have been meeting around this time each year for such a strain selection, a routine decision in the process of updating the life-saving vaccines.

But this year's meeting was awkward and even a little tense. Earlier this week, new FDA leaders under health secretary and anti-vaccine advocate Robert F. Kennedy Jr. announced a sweeping new framework that would restrict access to the shots , making them available only to people 65 and older and those with medical conditions that put them at risk of severe illness. For updated COVID-19 vaccines to be approved for healthy children and adults, vaccine makers would need to repeat large, randomized, placebo-controlled trials, which are expensive, ethically debatable at this point, and could easily take too much time to complete before the shots would need to be ready for fall vaccinations. The advisors weren't consulting on the new framework, and there is much uncertainty about its implementation.

Just thirty minutes into yesterday's nearly seven-hour meeting, one committee member broached one of the largest looming questions, saying, "If a different strain was selected for this season, would that require additional clinical trials, etc.?"

Donald Trump woke up Friday morning and threatened Apple with a 25 percent tariff on any iPhones sold in the US that are not manufactured in America.

In a Truth Social post, Trump claimed that he had "long ago" told Apple CEO Tim Cook that Apple's plan to manufacture iPhones for the US market in India was unacceptable. Only US-made iPhones should be sold here, he said.

"If that is not the case, a tariff of at least 25 percent must be paid by Apple to the US," Trump said.
