Lasers are great for heating things up, whether you need to do it quickly, hit a precise target, or do it from a distance. Under specific conditions, lasers can also cool things down, and that might be JUST what we need to tackle way-too-toasty data centers.
Using the unique infrared sensitivity of NASA’s James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early universe. Now, an international team of astronomers has identified bright hydrogen emission from a galaxy in an unexpectedly early time in the universe’s history. The surprise finding is challenging researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time.
The Webb telescope discovered the incredibly distant galaxy JADES-GS-z13-1, observed to exist just 330 million years after the big bang, in images taken by Webb’s NIRCam (Near-Infrared Camera) as part of the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES). Researchers used the galaxy’s brightness in different infrared filters to estimate its redshift, which measures a galaxy’s distance from Earth based on how its light has been stretched out during its journey through expanding space.
Amodei stressed that the integration of AI into daily life in the coming years should be a boon to humanity, not a menace or a job-destroying machine.
Artificial neural nets, called spiking neural networks (SNNs), could be used to create intelligent robots, or to better understand the underpinnings of the brain itself. Now researchers in India have achieved ultra-low energy artificial neurons that allow the SNNs to be more compactly arranged.

Questions about consciousness range from the precise and empirical — what neurons fire when I have some particular experience — to the deeply profound — does consciousness emerge from matter, or does matter emerge from consciousness? While it might be straightforward to think that consciousness arises from the collective behavior of atoms in the brain, Annaka Harris and others argue that consciousness could be the fundamental stuff from which matter arises. She talks with a variety of experts in her new audio series, Lights On: How Understanding Consciousness Helps Us Understand the Universe.
Annaka Harris received a BFA from New York University. She is the author of Consciousness: A Brief Guide to the Fundamental Mystery of the Mind. She is a co-founder of Project Reason.

In this video I explore how Sam Altman’s hints about GPT-4.5 and GPT-5 are reshaping the AI landscape. You’ll discover the key differences between GPT-4.5 and GPT-5, learn why OpenAI’s next release could unify “fast” and “thoughtful” AI models, and find out how chain-of-thought reasoning could change everything from creative writing to complex problem-solving. I also discuss the biggest challenges OpenAI has faced during GPT-5’s development—from massive data requirements to persistent engineering snags—and why this model might feel closer to AGI than any chatbot yet.

Using the DNA of the late musician Alvin Lucier, a team has created an “in-vitro brain” that still creates music with its electrical signals.
When a pregnant woman had her blood sampled back in 1972, doctors discovered it was mysteriously missing a surface molecule found on all other known red blood cells at the time.
After 50 years, this strange molecular absence finally led to researchers from the UK and Israel describing a new blood group system in humans. In 2024, the team published their paper on the discovery.
“It represents a huge achievement, and the culmination of a long team effort, to finally establish this new blood group system and be able to offer the best care to rare, but important, patients,” UK National Health Service hematologist Louise Tilley said last September, after nearly 20 years of personally researching this bloody quirk.
