AI maps brain waste-clearing flow, revealing two speeds tied to deep sleep
When a person goes into deep sleep, waterlike fluid circulates around the brain, washing away metabolic waste that is linked to diseases such as Alzheimer’s. This process, known as the glymphatic system, was first described in 2012 by Maiken Nedergaard, a pioneering neuroscientist and co-director of the University of Rochester Center for Translational Neuromedicine.
But questions remain about the system’s mechanics—notably, how quickly the fluid circulates around the brain. Studying the circulation within a living brain is difficult to do without causing irreparable harm to a subject.
“You can put a microscope on a small patch of the brain and watch what’s happening there with a lot of detail, and we’ve worked with that type of data in the past, but it’s only a tiny view of the overall process,” says Professor Douglas Kelley from the University of Rochester’s Department of Mechanical Engineering.
Researchers teach brain cells to play ‘Doom’
Investigadores enseñan a las células cerebrales a jugar a ‘Doom’
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the nineties shooter game “Doom” and say they are just scratching the surface of what the neurons could be capable of doing.
It’s the science-fiction work of biotech boffins at Cortical Labs, who researched and developed the technology that harnesses the workings of the brain’s networking system.
Each so-called “biological computer” contains around 200,000 living human brain cells, grown from stem cells that were harvested from blood donations.
DARPA wants to replace GPS dependence with new class of sensors
Every GPS signal on the battlefield is a vulnerability waiting to be exploited, and Russia, China, and Iran have all demonstrated the willingness to exploit it. DARPA just announced it is going to solve that problem from the inside out, by building a navigation sensor so precise that it no longer needs GPS to know exactly where it is.
The Defense Advanced Research Projects Agency, the Pentagon’s research arm responsible for developing technologies that define the next generation of American military capability, published a special notice on May 29, announcing the forthcoming PINPOINT program, formally titled Precision Inertial Navigation and Positioning On an Integrated Tesseract.
The program, managed through DARPA’s Defense Sciences Office by Program Manager Sunil Bhave, aims to develop a revolutionary approach to inertial navigation that would allow military platforms to maintain precise positioning even when GPS has been jammed, spoofed, or denied. A formal solicitation with specific technical requirements and performance metrics is expected in the near future, with industry responses to the preliminary notice accepted through July 13, 2026.
Super El Niño: How Accurate Are These Predictions?

According to predictions from weather organizations across the planet, a super El Niño weather event is likely to begin over the next few weeks. It’s predicted to drive up temperatures across the globe, bringing increased chances of heatwaves, drought, wildfires, and even famines – plus, this year’s El Niño is likely to be stronger than usual, making those effects worse. Let’s take a look.

In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot explosion of plasma kicked off the creation of the universe. But according to a new paper, the microwave radiation came from early galaxies instead. Does this mean that the big bang theory is wrong? Let’s take a look.

The fractures aren’t in our biology. They’re in our agreements, our economic systems, and our willingness to extend the definition of “us” to include the health minister in a lower-middle-income country holding a terrifying lab result and staring at a phone they are afraid to pick up.
