Tech Xplore / AI model edits can leak sensitive data via update 'fingerprints'
Artificial intelligence (AI) systems are now widely used by millions of people worldwide, as tools to source information or tackle specific tasks more rapidly and efficiently. Today, some of the most used are large language ...
Phys.org / Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics
A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation ...
Medical Xpress / Oxytocin reverses anxiety-like behavior after three months of isolation in mice
Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. ...
Phys.org / How fast is the universe expanding? Supernova could provide the answer
That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research team at the ...
Phys.org / Astronomers may have just found one of the missing links in galaxy evolution
A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion years after ...
Phys.org / Is dark energy actually evolving?
Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing the expansion of the ...
Phys.org / New generation of climate models sheds first light on long-standing Pacific puzzle
Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean accompanying global warming. Existing climate models have failed to capture this pattern. At the Max Planck ...
Phys.org / Supercomputer simulations reveal rotation drives chemical mixing in red giant stars
Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they evolve?
Phys.org / Hiding in plain sight: Discovery of cryptic species could double the number of vertebrates
There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's not because of any errors ...
Phys.org / Triplet superconductivity—physicists may have found the missing link for quantum computers
Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet—or understand why. Triplet superconductors could be the key to achieving the most energy-efficient ...
Tech Xplore / Laser-etched glass can store data for 10,000 years, Microsoft says
Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.
Phys.org / Chemists synthesize first stable copper metallocene complex, closing a 70-year gap
Almost half a century ago, a remarkable molecule called metallocene took center stage in chemistry, earning Geoffrey Wilkinson and Ernst Otto Fischer the Nobel Prize. These organic compounds, made of a transition metal "sandwiched" ...
