In 10 seconds, an AI model detects cancerous brain tumor often missed during surgery
Researchers have developed an AI powered model that -- in 10 seconds -- can determine during surgery if any part of a cancerous brain tumor that could be removed remains. The technology, called FastGlioma, outperformed conventional methods for identifying what remains of a tumor by a wide margin. Researchers say it has the potential to change the field of neurosurgery by immediately improving comprehensive management of patients with diffuse gliomas.

Meteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth and is one of the few meteorites that can be traced directly to Mars. This meteorite was rediscovered in a drawer at Purdue University in 1931 and therefore named the Lafayette Meteorite. During early investigations of the Lafayette Meteorite, scientists discovered that it had interacted with liquid water while on Mars. Scientists have long wondered when that interaction with liquid water took place. Scientists have recently determined the age of the minerals in the Lafayette Meteorite that formed when there was liquid water.
Organ donation: Opt-out defaults do not increase donation rates, study finds
A recent study shows that switching to an opt-out organ donation policy, where all adults are presumed organ donors unless they explicitly opt out, does not increase donations from deceased donors.
Gas-churning monster black holes
Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a galaxy.
On the origin of life: How the first cell membranes came to exist
Few questions have captivated humankind more than the origin of life on Earth. How did the first living cells come to exist? How did these early protocells develop the structural membranes necessary for cells to thrive and assemble into complex organisms? New research has uncovered a plausible explanation involving the reaction between two simple molecules.
Anti-fatberg invention could help unclog city sewers
Engineers have invented a protective coating for concrete pipes that could help drastically reduce the formation of fatbergs in sewers.
Bird brain from the age of dinosaurs reveals roots of avian intelligence
A 'one of a kind' fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.
Many bacterial-linked illnesses, such as inflammatory bowel disease or colorectal cancer, are associated with an overgrowth of gut bacteria thought to be bad actors. But when researchers used a machine learning algorithm to predict the density of microbes -- called microbial load, from their gut microbiomes, they found that changes in microbial load, rather than the disease, could be a driver behind the presence of disease-associated microbial species.
Three galactic 'red monsters' in the early Universe
Astronomers have identified three ultra-massive galaxies -- nearly as massive as the Milky Way -- already in place within the first billion years after the Big Bang. This surprising discovery was made possible by the James Webb Space Telescope's FRESCO program, which uses the NIRCam/grism spectrograph to measure accurate distances and stellar masses of galaxies. The results indicate that the formation of stars in the early Universe was far more efficient than previously thought, challenging existing galaxy formation models.
Can we live on our planet without destroying it?
How much land, water, and other resources does our lifestyle require? And how can we adapt this lifestyle to stay within the limits of what the Earth can give? A new article tackles these questions.
How to reduce social media stress by leaning in instead of logging off
Young people's mental health may depend on how they use social media, rather than how much time they spend using it. Psychology researchers tried an experiment with three groups. They asked one group to stay off social media. They taught another group how to use it more constructively. The third group stuck with their usual routine. The group that stayed away, AND the group that used it differently, both reported improvements in their mental health.
Building a diverse wildland fire workforce to meet future challenges
Wildland firefighters are under significant strain, often overworked and underpaid despite the growing need to respond to larger, more destructive fires. Building a more resilient and effective workforce will require improving pathways for diverse applicants, strengthening commitments to health equity, and investing in workplace culture, according to a new Stanford University report.
