Scientists at Kyushu University report that turning brain immune cells into neurons restores brain function after stroke-like injury in mice. Their findings suggest that replenishing neurons from immune cells could be a potential avenue for treating stroke in humans.

The findings are published in PNAS in an article titled, “Direct neuronal conversion of microglia/macrophages reinstates neurological function after stroke.”

“Although generating new neurons in the ischemic injured brain would be an ideal approach to replenish the lost neurons for repairing the damage, the adult mammalian brain retains only limited neurogenic capability,” wrote the scientists. “Here, we show that direct conversion of microglia/macrophages into neurons in the brain has great potential as a therapeutic strategy for ischemic brain injury.”

Tesla has shared a video of a hands-free drive demonstration of its Full Self-Driving suite in Austin. The FSD suite is not available to customers in a hands-free nature, but Tesla disabled the requirement for a new video it shared on X, formerly known as Twitter.

Tesla shared the video to demonstrate the capabilities of Software Version 11.4.7, which is the current version of the FSD Beta program.

The automaker describes in the Tweet in put up how the Full Self-Driving suite improves through data-driven techniques that refine the capabilities through analysis of other drivers’ behavior and normal navigation habits.

A recent study in Psychiatry Research: Neuroimaging revealed that individuals with high depression scores show increased activity in frontal brain regions during visuospatial memory tasks, despite similar behavioral performance to those with low depression scores. Researchers concluded that the heightened brain activity might represent a compensatory effort…

That spider you squished? It could have been used for science!

At least, that’s what Faye Yap and Daniel Preston think. Yap is a mechanical engineering PhD student in Preston’s lab at Rice University, where she co-authored a paper on reanimating spider corpses to create grippers, or tiny machines used to pick up and put down delicate objects. Yap and Preston dubbed this use of biotic materials for robotic parts “necrobotics” – and think this technique could one day become a cheap, green addition to the field.

A study published today by scientists from Harvard University and epigenetic research company TruDiagnostic has shed light on the reasons why our bodies are aging on a cellular level, laying the foundations for medical based treatment options to reduce the risk of age-related death and disease in highly targeted ways.

Longevity. Technology: Age is the number one risk factor for most chronic diseases and death across the world. Epigenetics (or the way our genes are put to use throughout our bodies) has emerged as a crucial method of evaluating health, and while previous DNA methylation clocks could determine how advanced one’s body has aged, they have not yet been able to provide information to the reasons why someone might have accelerated or decelerated aging outcomes.

“In our research, we set out to create the best method to quantify the biological aging process. However, aging is extremely complex,” explains Harvard Medical School Associate Professor Dr Jessica Lasky-Su. “To solve this issue of complexity, our approach was to gather data across multiple sources of information. We chose to do this by building one of the most robust aging datasets in the world by quantifying patients’ proteomics, metabolomics, clinical histories and DNA methylation.”

The number of Star Trek sci-fi technology that ultimately became real-life tech never ceases to amaze. The series inspired the development of touchscreens, communicators became mobile phones, PAADs became tablets, replicators became 3D printing, and now holodecks are becoming virtual and augmented realities (VRs and ARs). And while fully immersive environments like the holodeck still remain in the realm of sci-fi, a recent report from BBC on a hologram zoo indicates that the future isn’t so far-fetched when it comes to immersive holographic.

The holograms use a new depth technology that not only makes the animals seem big but makes them visible as 3D objects rather than suspended 2D images.

According to the report, the visitors of Australia’s Hologram Zoo, which opened earlier this year, can dodge stampeding elephants, peer into the gaping jaws of a hippopotamus, pet-friendly giraffes, and witness more than 50 lifelike displays from dinosaurs to gorillas—all crafted from concentrated beams of light.
