Indian Scientists Produce Most Detailed 3D Atlas of the Human Brainstem

Scientists at the Indian Institute of Technology, Madras (IIT-M) have created what they describe as the world's most detailed 3D cellular atlas of the human brainstem, linking whole-brain MRI views to individual neurons across more than 500 tissue sections. The free online atlas, called Anchor, could help researchers better understand diseases such as Alzheimer's, Parkinson's, stroke, and SIDS by showing how healthy and diseased brain tissue differs cell by cell. The BBC reports: Built from high-resolution microscope images rather than costlier molecular techniques, it creates a detailed three-dimensional map of the brainstem, identifying more than 200 clusters of brain cells and nerve pathways. Eight chemical markers help distinguish different cell types, producing one of the clearest pictures yet of this vital, but poorly, understood part of the brain. The brainstem occupies only a sliver of the brain, yet it keeps people alive. It links the brain to the spinal cord and controls breathing, heartbeat, sleep, wakefulness and movement. [...] Users can zoom from the whole brainstem seen on MRI down to individual neurons while maintaining their precise spatial relationships. The researchers have made the atlas freely available online, hoping it becomes a reference tool for neuroscientists, neurologists and neurosurgeons worldwide. Its applications could also extend well beyond anatomy. By comparing healthy brainstem maps with diseased tissue, scientists may better understand disorders ranging from Parkinson's disease and stroke to Alzheimer's disease and sudden infant death syndrome (SIDS). More precise maps could also help neurosurgeons navigate one of the brain's most delicate regions with greater confidence.

Scientists Find Sugar Deep In Our Galaxy

Astronomers have detected erythrulose, a sugar found in raspberries and self-tanners, in a gas cloud near the center of the Milky Way. While not essential for life itself, the molecule can convert into a form thought to be important for life's origins, adding evidence that key prebiotic ingredients may be widespread across the galaxy. The Associated Press reports: Using two dish-shaped radio telescopes in Spain, researchers collected data from a large gas cloud near the center of the Milky Way. They identified the sugar in gas form by comparing telescope signals to samples in the lab. It's the latest kind of sugar detected in space -- in a region crossed by NASA's twin Voyager, the farthest spacecraft to ever travel from Earth. Scientists have found interesting chemistry in our galaxy, including building blocks for genetic material and parts of the cell. They spotted a cousin to table sugar near the center of the Milky Way about 25 years ago, and black grains from asteroid Bennu retrieved by NASA's Osiris-Rex spacecraft yielded other sugars, including a key DNA ingredient. The latest sugar isn't essential for life, but can easily convert to a form that's thought to be crucial to kick-starting life on Earth. And it's one of the most complex sugars spotted so far, said astrophysicist Erika Hamden with the University of Arizona. The results were published in the journal Nature Astronomy.

Over 200 Economists Say 'We Must Act Now' On AI's Economic Impact

An anonymous reader quotes a report from the Associated Press: Hundreds of economists say in an open letter that institutions "must act now" to address how artificial intelligence could transform the economy and could put many people out of work. The statement released Monday was signed by top economists, along with computer scientists and some executives at tech companies including Anthropic, Google and OpenAI. "AI may become radically more powerful over the next 10 years," says the letter organized by Stanford University's digital economy lab. "This could drive an unprecedented transformation of our economy, larger than the Industrial Revolution, but unfolding over a vastly shorter time frame. It could bring risks, including large-scale job displacement, as well as opportunities such as major gains in living standards." The letter, which has only four sentences, says leaders must "build the incentives, guardrails, and institutions needed to steer AI in a direction that complements humans and benefits society." The Stanford lab says the letter has so far been signed by more than 200 economists and AI researchers, including 16 winners of a Nobel Prize. "We must be intentional and make collective, democratic choices, rather than letting market forces play out and risking leaving most citizens behind," wrote computer scientist and AI pioneer Yoshua Bengio, who was also among the signatories. He said it "it is highly plausible that AI will drastically transform our economies." Other signatories include Google CEO Eric Schmidt, LinkedIn cofounder Reid Hoffman, and Nobel laureates Joseph Stiglitz, Daron Acemonglu, and Simon Johnson.
