Reveals 2 percent threshold governs all black holes
An international team led by Andrew Mummery and Adelle Goodwin discovered that black holes of all sizes launch jets at the same critical point in their feeding cycle. By studying 20 tidal disruption events using optical, ultraviolet, X-ray, and radio observations, they found jets form when accretion rates drop to 2 percent of the Eddington limit—the same threshold governing small black holes in the Milky Way.

Reveals cancer risk in 405 men, University of Arizona
A study led by Dr. Dan Theodorescu at the University of Arizona Cancer Center found that loss of the Y chromosome in normal tissue adjacent to tumors may signal early cancer formation. Analyzing 1,000 tissue samples and over 4.3 million cell nuclei, researchers discovered a gradient of Y chromosome loss correlating with cancer development across bladder, colon, rectum, esophagus, pancreas, and lung tissues.

Ranks fourth or fifth least severe since 1992
The Antarctic ozone hole in 2025 was among the smallest in decades, ranking fourth or fifth least severe since 1992, according to the World Meteorological Organization. This marks the second consecutive year with below-average depth and extent. The recovery follows the 1987 Montreal Protocol, which phased out ozone-depleting chlorofluorocarbons. The ozone layer is expected to fully recover within several decades.

Steers light beam in 74 femtoseconds, Caltech breakthrough
Caltech researchers have developed a device that redirects one light beam using another in 74 femtoseconds—about the time light takes to cross a human hair's width. The team, led by Harry Atwater, used optical meta-surfaces and the optical Kerr effect to achieve ultrafast photonic control, steering beams by up to 13 degrees without slowing light's speed.

Stanford reveals brain arose from two distinct progenitors
Stanford Medicine researchers discovered the human brain develops from two independent progenitor cells that evolved separately over hundreds of millions of years, not from a single universal source. Using mouse embryos and human stem cells, scientists found the forebrain and midbrain arise from cells marked by Otx2 gene, while hindbrain develops from Gbx2-marked cells on a parallel track. This breakthrough explains laboratory difficulties growing hindbrain neurons and may advance treatments for SMA and ALS.

Scientists measure T. rex body heat at 36.3°C
Paleontologists analyzed clumped isotopes in three T. rex teeth from Montana's Hell Creek Formation, revealing a body temperature of 36.3 ± 2.5°C—matching modern mammals and birds. This warm-blooded physiology allowed T. rex to thrive across North America, even in cooler regions, and explains its dominance as a top predator requiring vast amounts of food.

NASA maps Earth's mass movements millimeters quarterly
NASA's Jet Propulsion Laboratory developed a new method combining GPS tracking and satellite data to accurately measure Earth's center-of-mass shifts caused by atmospheric, oceanic, and water movements. The hybrid approach reduces uncertainty by incorporating low-Earth-orbit satellites and accounting for crustal distortion from water and ice weight. Previous estimates from 2017 and 2023 differed by 7 millimeters.

Spots largest crater in 222 meters via LRO
NASA's Lunar Reconnaissance Orbiter detected the largest newly formed crater on the Moon, a 222-meter-diameter impact named McGetchin. The crater, created by a comet or asteroid in spring 2024, represents a once-in-132-year event. Located on the Moon's eastern edge, it extends 141 feet deep and shows how the lunar surface undergoes constant change despite lacking atmospheric protection.

Recreated 10-second clips from visual cortex neurons
Researchers at University College London decoded what mice saw by recording single neuron activity in their visual cortex using calcium imaging. They reconstructed short video clips from brain signals, then tested the method on unseen footage. The reconstructions captured essential structure and motion, showing the brain's interpretation isn't a perfect copy but highlights, excludes, and distorts reality.

Researchers transplant human neurons into genetically engineered mice
Stanford Medicine scientists successfully implanted human cortical organoids into genetically engineered mice lacking most of their own cortex, creating hybrid xenocortical mice. The human neurons survived, grew, formed neural circuits, and connected with mouse spinal cord. Within months, over 90 percent of cortical tissue was human origin, revealing rare von Economo neurons never before seen in lab culture.

Study reveals real-time viral assembly Nature
Researchers at Oxford used mass photometry and single-molecule trapping to watch virus-like particles assemble piece by piece in real time. They discovered the process starts with weak, reversible interactions where protein building blocks collide and form temporary bonds. When five larger protein units form a pentagonal ring, a stable structure emerges that guides the assembly forward, making the process both reliable and efficient.

Confirms youngest planet Elias 2-24 b, 450 light-years away
Astronomers using NASA-funded data discovered Elias 2-24 b, the youngest known planet at less than a million years old, orbiting star Elias 2-24 about 450 light-years away. The Jupiter-sized planet remains embedded in its dusty birth disk. This discovery challenges existing planet-formation models, which previously struggled to explain planets older than 5 million years.
