Tech Xplore / AI reduces sensory hallucinations, even at night or in smoke

Multimodal large language models (MLLMs), which process multiple types of sensory information, such as text, images and audio, at the same time, are rapidly expanding the range of applications for artificial intelligence ...

Phys.org / 2D quantum memory device reaches single-electron limit of information storage

Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...

Phys.org / Two Arctic charr populations evolved in less than a century, study finds

Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster ...

Phys.org / A new genetic tool helps researchers uncover the logic of gene regulation

The human genome contains more than 20,000 genes. However, at any given time and in a given cell, only a fraction are active. Researchers from EMBL Heidelberg's Krebs Group have developed an innovative experimental approach ...

Phys.org / Rainfall across the US is increasingly coming from farther away

Before rain falls, the moisture that forms it may have traveled anywhere from just a few kilometers to hundreds or even thousands of kilometers away. It usually begins as water that evaporated from oceans, lakes, forests ...

Phys.org / Ancient diamond preserves evidence of water-bearing mineral deep in Earth's mantle

A team of Brazilian researchers discovered the first direct evidence that goethite—the mineral responsible for the brown color of soils—can withstand extreme pressures and temperatures all the way to the planet's interior ...

Medical Xpress / Scientists identify fructose as a surprise driver of cancer spread

A new study from The Wistar Institute has uncovered an unexpected link between fructose—a common dietary sugar—and the spread of an aggressive form of ovarian cancer. Published in Nature Aging, the study found that cancer ...

Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought

Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...

Phys.org / Evidence of giant rings in Venus's atmosphere uncovered in archived observations

In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. They were waiting for the sun to set so they could look at distant stars and dust disks ...

Science X / Curious people embrace richer experiences, but cognitive test scores tell a more complicated story

We often hear that a curious mind is a sharp mind, particularly as we age. According to scientists, persistent learners are often open to taking on new challenges and trying new activities. The idea is that engaging with ...

Tech Xplore / Popular vs. reliable sources—a blind spot in how LLMs assess information

Large language models (LLMs), the artificial intelligence (AI) systems underpinning ChatGPT and similar conversational platforms, are now used by many people worldwide to find and summarize information and generate different ...

Medical Xpress / Sleep replay of learned skills can occur independently of the hippocampus, mouse study finds

Sleep is a crucial physiological process that supports recovery, clears metabolic waste products from the brain, regulates metabolism and supports the functioning of the immune system. Sleep is also known to play a key role ...
