Phys.org / Prehistoric 'giant rat' found in Thailand from fossil teeth
A giant rodent weighing around 30 kilograms (66 pounds) roamed what is now southern Thailand 33 to 35 million years ago, scientists said, after identifying a previously unknown species from two fossilized teeth.
Medical Xpress / Advanced imaging uncovers genomic Achilles' heel that makes cancer cells vulnerable
A small subset of vulnerable DNA sites can make cancer cells highly sensitive to targeted drugs called PARP inhibitors, a new study shows. Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the work ...
Phys.org / Fractal patterns reveal hidden limits to AI predictability
Researchers at the University of Sydney have identified a fundamental mathematical reason why artificial intelligence systems can learn different behaviors even when trained under almost identical conditions, a discovery ...
Tech Xplore / Let there be light—novel AI framework runs on optical hardware
Artificial intelligence is increasingly pervasive and capable but is also very hungry for power. Researchers, including those at the University of Tokyo, have developed a new approach to building physics-based AI—systems ...
Phys.org / Google turns off AI for schoolchildren by default
Google has said it will switch off its AI tools for schoolchildren by default, after drawing criticism for pushing artificial intelligence features to students while schools are still debating how the technology should be ...
Tech Xplore / Nintendo producer 'all nervous' as Zelda classic remake hits shelves
He has been behind some of Nintendo's biggest hits, but producer Eiji Aonuma still feels "nervous" as he awaits players' reactions to the new Zelda video game, "Ocarina of Time," out Nov. 5.
Medical Xpress / How an enriched environment promotes brain plasticity—study identifies the molecular mechanisms
A meta-analysis on the effects of environmental enrichment on the rodent brain has identified common patterns in the expression of genes associated with communication between neurons and synaptic plasticity, processes that ...
Tech Xplore / Community colleges rush to expand semiconductor training as labor shortage looms over US chip industry
For three years, Ethan Mock worked part time at a gym to make ends meet while taking on more than $100,000 in debt to pursue a degree in business administration. Earlier this year—his fifth and final at Northern Arizona University—he ...
Phys.org / Australia approves seabed site where a Japanese company will store carbon pollution
Australia has designated a seabed storage site near its northern coast where a Japanese company plans to store massive amounts of carbon pollution using a technology that has divided climate scientists.
Phys.org / European orbiter detects fresh hints of volcanic activity on Mars
New evidence from gas seeping above volcanic rifts suggests Mars is not geologically dead deep inside, but merely sleeping. Fresh fissures along the Alba Mons region hint at active spots under the surface, where gases from ...
Phys.org / Centuries-old cemetery helps scientists link climate shocks to Industrial Revolution disease
During England's Industrial Revolution, when the country's farming-based economy transformed into an industrial one between roughly 1760 and 1840, pollution, harsh working conditions, inadequate housing and limited access ...
Phys.org / Evolution has repeatedly turned hawkmoth genitals into defensive tools
The genital structures of male hawkmoths are lifesavers. By rubbing specialized scales on their genitals against parts of their abdomen, the nocturnal insects emit ultrasonic sounds that can potentially scramble the acoustic ...
