One-quarter of the world’s population is currently water-stressed , using up almost their entire fresh water supply each year. The UN predicts that by 2030, this will climb to two-thirds of the population .

Freshwater is perhaps the world’s most essential resource, but climate change is enhancing its scarcity. An unexpected source may have the potential to provide some relief: offshore aquifers, giant undersea bodies of rock or sediment that hold and transport freshwater. But researchers don’t know how the water gets there, a question that needs to be resolved if we want to understand how to manage the water stored in them.

For decades, scientists have known about an aquifer off the US East Coast. It stretches from Martha’s Vineyard to New Jersey and holds almost as much water as two Lake Ontarios. Research presented at the American Geophysical Union conference in December attempted to explain where the water came from—a key step in finding out where other undersea aquifers lie hidden around the world.

There are games for which I have great admiration, pleasant memories, and an entirely dreadful set of skills and outcomes. Heroes of Might & Magic III (or HoMM 3 ) has long been one of those games.

I have played it on just about every PC I've owned, ever since it chipped away at my college GPA. I love being tasked with managing not only heroes, armies, resources, villages, and battlefield positioning but also time itself. If you run around the map clicking to discover every single power-up and resource pile, using up turn after turn, you will almost certainly let your enemy grow strong enough to conquer you. But I do this, without fail. I get halfway into a campaign and the (horse cart) wheels fall off, so I set the game aside until the click-to-move-the-horsey impulse comes back.

With the release of Songs of Conquest in 1.0 form on PC today ( Steam , GOG , Epic ), I feel freed from this loop of recurrent humbling. This title from Lavapotion and Coffee Stain Publishing very much hits the same pleasure points of discovery and choice as HoMM 3 . But Songs of Conquest has much easier onboarding, modern resolutions, interfaces that aren't too taxing (to the point of being Verified on Steam Deck), and granular difficulty customization . More importantly for most, it has its own stories and ideas. If you love fiddling with stuff turn by turn, it's hard to imagine you won't find something in Songs of Conquest to hook you.

There are a couple of ways to read the announcement from the Federal Aviation Administration that it's kicking off a new environmental review of SpaceX's plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX's proposal to launch Starships from NASA's Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

Dual environmental reviews

At the same time, the US Space Force is overseeing a similar EIS for SpaceX's proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37 ), is available for use after United Launch Alliance's last Delta rocket lifted off there in April.

An asteroid that has been wandering through space for billions of years is going to have been bombarded by everything from rocks to radiation. Billions of years traveling through interplanetary space increase the odds of colliding with something in the vast emptiness, and at least one of those impacts had enough force to leave the asteroid Ryugu forever changed.

When the Japanese Space Agency’s Hayabusa2 spacecraft touched down on Ryugu, it collected samples from the surface that revealed that particles of magnetite (which is usually magnetic) in the asteroid’s regolith are devoid of magnetism. A team of researchers from Hokkaido University and several other institutions in Japan are now offering an explanation for how this material lost most of its magnetic properties. Their analysis showed that it was caused by at least one high-velocity micrometeoroid collision that broke the magnetite’s chemical structure down so that it was no longer magnetic.

“We surmised that pseudo-magnetite was created [as] the result of space weathering by micrometeoroid impact,” the researchers, led by Hokkaido University professor Yuki Kimura, said in a study recently published in Nature Communications.

Ruth Ann Norton used to look forward to seeing the blue flame that danced on the burners of her gas stove. At one time, she says, she would have sworn that preparing meals with the appliance actually made her a better cook.

But then she started learning about the toxic gasses, including carbon monoxide, formaldehyde and other harmful pollutants that are emitted by stoves into the air, even when they’re turned off .

“I’m a person who grew up cooking, and love that blue flame,” said Norton, who leads the environmental advocacy group known as the Green & Healthy Homes Initiative . “But people fear what they don’t know. And what people need to understand really strongly is the subtle and profound impact that this is having—on neurological health, on respiratory health, on reproductive health.”

In July last year, OpenAI announced the formation of a new research team that would prepare for the advent of supersmart artificial intelligence capable of outwitting and overpowering its creators. Ilya Sutskever, OpenAI’s chief scientist and one of the company’s co-founders, was named as the co-lead of this new team. OpenAI said the team would receive 20 percent of its computing power.

Now OpenAI’s “superalignment team” is no more, the company confirms. That comes after the departures of several researchers involved, Tuesday’s news that Sutskever was leaving the company, and the resignation of the team’s other co-lead. The group’s work will be absorbed into OpenAI’s other research efforts.

Unraveling how consciousness arises out of particular configurations of organic matter is a quest that has absorbed scientists and philosophers for ages. Now, with AI systems behaving in strikingly conscious-looking ways, it is more important than ever to get a handle on who and what is capable of experiencing life on a conscious level. As Christof Koch writes in Then I Am Myself the World , "That you are intimately acquainted with the way life feels is a brute fact about the world that cries out for an explanation." His explanation—bounded by the limits of current research and framed through Koch’s preferred theory of consciousness—is what he eloquently attempts to deliver.

Koch, a physicist, neuroscientist, and former president of the Allen Institute for Brain Science, has spent his career hunting for the seat of consciousness, scouring the brain for physical footprints of subjective experience. It turns out that the posterior hot zone, a region in the back of the neocortex, is intricately connected to self-awareness and experiences of sound, sight, and touch. Dense networks of neocortical neurons in this area connect in a looped configuration; output signals feedback into input neurons, allowing the posterior hot zone to influence its own behavior. And herein, Koch claims, lies the key to consciousness.

In the hot zone

According to integrated information theory (IIT)—which Koch strongly favors over a multitude of contending theories of consciousness—the Rosetta Stone of subjective experience is the ability of a system to influence itself: to use its past state to affect its present state and its present state to influence its future state.

With the debut of remarkably effective weight-loss drugs, America's high obesity rate and its uniquely astronomical prescription drug pricing appear to be set on a catastrophic collision course—one that threatens to "bankrupt our entire health care system," according to a new Senate report that modeled the economic impact of the drugs in different uptake scenarios.

If just half of the adults in the US with obesity start taking a new weight-loss drug, such as Wegovy, the collective cost would total an estimated $411 billion per year, the analysis found. That's more than the $406 billion Americans spent in 2022 on all prescription drugs combined.

While the bulk of the spending on weight-loss drugs will occur in the commercial market—which could easily lead to spikes in health insurance premiums—taxpayer-funded Medicare and Medicaid programs will also see an extraordinary financial burden. In the scenario that half of adults with obesity go on the drug, the cost to those federal programs would total $166 billion per year, rivaling the programs' total 2022 drug costs of $175 billion.

Apple’s initial pitch for the tvOS and the Apple TV as it currently exists was centered around apps . No longer a mere streaming box, the Apple TV would also be a destination for general-purpose software and games, piggybacking off of the iPhone's vibrant app and game library.

That never really panned out, and the Apple TV is still mostly a box for streaming TV shows and movies. But the same App Store rule change that recently allowed Delta , PPSSPP , and other retro console emulators onto the iPhone and iPad could also make the Apple TV appeal to people who want a small, efficient, no-fuss console emulator for their TVs.

So far, few of the emulators that have made it to the iPhone have been ported to the Apple TV. But earlier this week, the streaming box got an official port of RetroArch, the sprawling collection of emulators that runs on everything from the PlayStation Portable to the Raspberry Pi. RetroArch could be sideloaded onto iOS and tvOS before this, but only using awkward workarounds that took a lot more work and know-how than downloading an app from the App Store.
