Sleep apnea events during REM sleep are linked to verbal memory impairment in older adults at risk for Alzheimer's disease. The research highlights the importance of focusing on sleep-stage-specific apnea severity for ac...

A new study found that some people lack an inner voice, termed "anendophasia," impacting their verbal memory and rhyme recognition. Participants without an inner voice struggled more with these tasks compared to those wi...

Neuroengineers discovered that certain brain cells age faster than others, particularly in Alzheimer's patients. Using a new technique called MUSIC, they identified distinct aging patterns in brain cells and sex-specific...

Researchers discovered that SARS-CoV-2 can penetrate the blood-retinal barrier, potentially causing long-term eye damage.

Researchers developed tiny "mini-brains" from stem cells to help diagnose and treat Alzheimer's disease. These mini-brains, created from human blood, accurately reflect the pathology of Alzheimer's on a smaller scale. Th...

A new study challenges the belief that average-sounding voices are always more attractive. Researchers found that pitch, rather than averageness, plays a crucial role in vocal attractiveness.

Despite its promising characteristics in condensed matter physics, the triply-degenerate semimetal PtBi2 has been largely unexplored in practical applications, particularly in semiconductor technology. The main difficult...

Researchers are exploring how fever can temporarily improve autism symptoms. They aim to understand the cellular and molecular mechanisms behind this "fever effect" to develop therapies that mimic it.

A DNA analysis of Ludwig van Beethoven's hair shows that he likely had lead poisoning.

Researchers use AI to reveal distinct cellular-level differences in the brains of men and women, focusing on white matter. These findings show AI can accurately identify sex-based brain patterns invisible to human eyes.

Dreaming helps prioritize and diminish the severity of emotionally charged memories. Participants who reported dreaming had better recall and were less reactive to negative images.

The interaction of solids with high-intensity ultra-short laser pulses has enabled major technological breakthroughs over the past half-century. On the one hand, laser ablation of solids offers micromachining and miniatu...

ChatGPT's latest upgrade means the voice assistant can now respond to audio, text and visual inputs in real time. The new chatbot, named ChatGPT-4o, will be rolled out to alpha testers in the coming weeks.

Using a clever laser technique, scientists have squished pairs of atoms closer together than ever before, revealing some truly mind-boggling quantum effects.

Advanced information processing technologies offer greener telecommunications and strong data security for millions, a study led by University of Maryland (UMD) researchers revealed.

Since the inception of microcomb, whose generation relies on Kerr nonlinearity in microresonator, the coherent soliton state has attracted intense research. Although the operation of sub-comb outputs is straightforward, ...

Researchers have developed new optical tweezers that can stably trap particles that are large--about 0.1 mm--and irregularly shaped. While conventional optical tweezers use highly focused laser beams to trap micro- or na...

From how well they work to side effects such as hair loss, here's the skinny on new weight loss injections that work by blocking a hormone that normally reduces appetite

The nasal flu vaccine may reduce cases of pneumonia illness in population over the whole flu season because flu infections are likely to lead to even higher boost in bacteria

Gravitational waves can be lensed by massive galaxies so that they repeat, like an echo. Scientists are now readying to snare their first one and explore the cosmic secrets it holds

Japan has announced plans to add fin whales -- the second-largest animal on Earth -- to its list of commercial whaling species, which currently includes Bryde's, sei and minke whales.

Tree rings suggest the Northern Hemisphere summer of 2023 was the hottest in 2,000 years, with temperatures exceeding those of the coldest summer in the same period by 7 degrees Fahrenheit (3.9 Celsius).
