The weird way Alabama’s embryo ruling takes on artificial wombs

A ruling by the Alabama Supreme Court last week that frozen embryos count as children is sending “shock waves” through the fertility industry and stoking fears that in vitro fertilization is getting swept up into the abortion debate.

The Alabama legal ruling is clearly animated by religion. But what hasn’t gotten much notice is the court’s specific argument that an embryo is a child “regardless of its location.” This could have implications for future technologies in development, such as artificial wombs or synthetic embryos made from stem cells. Read the full story.

Remote learning can work for preschoolers

Educational interruptions due to the pandemic, climate disasters, and war have affected nearly every child on Earth since 2020. A record 43.3 million children have been driven from their homes by conflict and disasters, according to UNICEF—a number that doubled over the past decade. Despite that, less than 2% of humanitarian aid worldwide goes to supporting young kids’ care and education.

That may be about to change, thanks to a program called Ahlan Simsin, a special version of Sesame Street that has been custom-made for Syrian refugee children. It’s the largest-ever humanitarian intervention intended for small children’s development, with remote learning a core part of it. And it’s already yielding promising early evidence that remote learning can help young children in crisis situations. Read the full story.

The Download: Neuralink’s biggest rivals, and the case for phasing out the term “user”

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Beyond Neuralink: Meet the other companies developing brain-computer interfaces

In the world of brain-computer interfaces, it can seem as if one company sucks up all the oxygen in the room. Last month, Neuralink posted a video to X showing the first human subject to receive its brain implant, which will be named Telepathy. The recipient, a 29-year-old man who is paralyzed from the shoulders down, played computer chess, moving the cursor around with his mind.

Neuralink’s announcement of a first-in-human trial made a big splash not because of what the man was able to accomplish—scientists demonstrated using a brain implant to move a cursor in 2006—but because the technology is so advanced.

But Neuralink isn’t the only company developing brain-computer interfaces to help people who have lost the ability to move or speak. Read on to take a look at some of the companies developing brain chips, their progress, and their different approaches to the technology.

It’s time to retire the term “user”

People have been called “users” for a long time; it’s a practical shorthand enforced by executives, founders, operators, engineers, and investors ad infinitum.

Often, it is the right word to describe people who use software: a user is more than just a customer or a consumer. Sometimes a user isn’t even a person; corporate bots are known to run accounts on Instagram and other social media platforms, for example.

But “users” is also unspecific enough to refer to just about everyone. It can accommodate almost any big idea or long-term vision. We use—and are used by—computers and platforms and companies. Though “user” seems to describe a relationship that is deeply transactional, many of the technological relationships in which a person would be considered a user are actually quite personal. That being the case, is “user” still relevant? Read the full story.

Three ways the US could help universities compete with tech companies on AI innovation

—Ylli Bajraktari, CEO of nonprofit the Special Competitive Studies Project, Tom Mitchell, the Founders University Professor at Carnegie Mellon University, and Daniela Rus, a professor of electrical engineering and computer science at MIT

The ongoing revolution in artificial intelligence has the potential to dramatically improve our lives. Yet ensuring that America and other democracies can help shape the trajectory of this technology requires going beyond the tech development taking place at private companies.

Research at universities drove the AI advances that laid the groundwork for the commercial boom we are experiencing today. But large AI models require such vast computational power and such extensive data sets that private companies have replaced academia at the frontier of AI. Here’s a few ideas for how the US could empower its universities to remain alongside them at the forefront of AI research.

How to build a thermal battery

This article is from The Spark, MIT Technology Review’s weekly climate newsletter. To receive it in your inbox every Wednesday, sign up here

The votes have been tallied, and the results are in. The winner of the 11th Breakthrough Technology, 2024 edition, is … drumroll please … thermal batteries!

While the editors of MIT Technology Review choose the annual list of 10 Breakthrough Technologies, in 2022 we started having readers weigh in on an 11th technology. And I don’t mean to flatter you, but I think you picked a fascinating one this year.

Thermal energy storage is a convenient way to stockpile energy for later. This could be crucial in connecting cheap but inconsistent renewable energy with industrial facilities, which often require a constant supply of heat.

I wrote about why this technology is having a moment, and where it might wind up being used, in a story published Monday. For the newsletter this week, let’s take a deeper look at the different kinds of thermal batteries out there, because there’s a wide world of possibilities. 

Step 1: Choose your energy source

In the journey to build a thermal battery, the crucial first step is to choose where your heat comes from. Most of the companies I’ve come across are building some sort of power-to-heat system, meaning electricity goes in and heat comes out. Heat often gets generated by running a current through a resistive material in a process similar to what happens when you turn on a toaster.

Some projects may take electricity directly from sources like wind turbines or solar panels that aren’t hooked up to the grid. That could reduce energy costs, since you don’t have to pay surcharges built into grid electricity rates, explains Jeffrey Rissman, senior director of industry at Energy Innovation, a policy and research firm specializing in energy and climate. 

Otherwise, thermal batteries can be hooked up to the grid directly. These systems could allow a facility to charge up when electricity prices are low or when there’s a lot of renewable energy on the grid.

Some thermal storage systems are soaking up waste heat rather than relying on electricity. Brenmiller Energy, for example, is building thermal batteries that can be charged up with heat or electricity, depending on the customer’s needs.

Depending on the heat source, systems using waste heat may not be able to reach temperatures as high as their electricity-powered counterparts, but they could help increase the efficiency of facilities that would otherwise waste that energy. There’s especially high potential for high-temperature processes, like cement and steel production.

Step 2: Choose your storage material

Next up: pick out a heat storage medium. These materials should probably be inexpensive and able to reach and withstand high temperatures.

Bricks and carbon blocks are popular choices, as they can be packed together and, depending on the material, reach temperatures well over 1,000 °C (1,800 °F). Rondo Energy, Antora Energy, and Electrified Thermal Solutions are among the companies using blocks and bricks to store heat at these high temperatures.

Crushed-up rocks are another option, and the storage medium of choice for Brenmiller Energy. Caldera is using a mixture of aluminum and crushed rock.

Molten materials can offer even more options for delivering thermal energy later, since they can be pumped around (though this can also add more complexity to the system). Malta is building thermal storage systems that use molten salt, and companies like Fourth Power are using systems that rely in part on molten metals.

Step 3: Choose your delivery method

Last, and perhaps most important, is deciding how to get energy back out of your storage system. Generally, thermal storage systems can deliver heat, use it to generate electricity, or go with some combination of the two.

Delivering heat is the most straightforward option. Typically, air or another gas gets blown over the hot thermal storage material, and that heated gas can be used to warm up equipment or to generate steam.

Some companies are working to use heat storage to deliver electricity instead. This could allow thermal storage systems to play a role not only in industry but potentially on the electrical grid as an electricity storage solution. One downside? These systems generally take a hit on efficiency, the amount of energy that can be returned from storage. But they may be right for some situations, such as facilities that need both heat and electricity on demand. Antora Energy is aiming to use thermophotovoltaic materials to turn heat stored in its carbon blocks back into electricity.

Some companies plan to offer a middle path, delivering a combination of heat and electricity, depending on what a facility needs. Rondo

The Download: American’s hydrogen train experiment, and why we need boring robots

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology

Hydrogen trains could revolutionize how Americans get around

Like a mirage speeding across the dusty desert outside Pueblo, Colorado, the first hydrogen-fuel-cell passenger train in the United States is getting warmed up on its test track. It will soon be shipped to Southern California, where it is slated to carry riders on San Bernardino County’s Arrow commuter rail service before the end of the year.

The best way to decarbonize railroads is the subject of growing debate among regulators, industry, and activists. The debate is partly technological, revolving around whether hydrogen fuel cells, batteries, or overhead electric wires offer the best performance for different railroad situations. But it’s also political: a question of the extent to which decarbonization can, or should, usher in a broader transformation of rail transportation.

In the insular world of railroading, this hydrogen-powered train is a Rorschach test. To some, it represents the future of rail transportation. To others, it looks like a big, shiny distraction. Read the full story.

Researchers taught robots to run. Now they’re teaching them to walk

We’ve all seen videos over the past few years demonstrating how agile humanoid robots have become, running and jumping with ease. We’re no longer surprised by this kind of agility—in fact, we’ve grown to expect it.

The problem is, these shiny demos lack real-world applications. When it comes to creating robots that are useful and safe around humans, the fundamentals of movement are more important.

As a result, researchers are using the same techniques to train humanoid robots to achieve much more modest goals. They believe it will lead to more robust, reliable two-legged machines capable of interacting with their surroundings more safely—as well as learning much more quickly. Read the full story.
