Women who experience menopause before age 40 are more likely to face cognitive decline than those who enter menopause after age 50. The findings, based on longitudinal data from nearly 5,000 women, suggest that early men...

A new study shows that gold nanoparticles injected into the retina can restore vision in mice with retinal degeneration, offering a less invasive alternative to current retinal prostheses. When activated by patterned inf...

New research reveals that individual neurons follow multiple learning rules simultaneously, challenging the long-held belief that synaptic plasticity operates uniformly throughout the brain. Using advanced two-photon ima...

Researchers at the European XFEL have developed a new device for X-ray measurements at high photon energies--a so-called Laue spectrometer. It enables X-ray light with photon energies of more than 15 kiloelectronvolts to...

A new study reveals that women can subconsciously judge potential friendship compatibility based on scent during first-time meetings. Researchers found that a person's everyday odor--captured on a worn T-shirt--predicted...

A team of Rice University researchers has developed a new way to control light interactions using a specially engineered structure called a 3D photonic-crystal cavity. Their work, published in the journal Nature Communic...

A CDC report analyzing data from 16 U.S. sites, including Maryland, found that autism now affects 1 in 31 eight-year-olds nationwide. Maryland's prevalence was slightly lower, with 1 in 38 eight-year-olds and 1 in 41 fou...

Imagine the tiniest game of checkers in the world--one played by using lasers to precisely shuffle around ions across a very small grid.

Two studies found stem-cell therapies were safe and reduced symptoms, but bigger trials are still needed. The post Parkinson’s Patients Say Their Symptoms Eased After Receiving Millions of New Brain Cells appeared firs...

In a physics first, a team including scientists from the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons travel in curves. These Airy beams (named for English scientist G...

The drugmaker Lilly announced topline results of a clinical trial of a new pill in the same drug class as injectables like Ozempic.

Samples drilled by the Curiosity rover on Mars have revealed abundant signs of a carbon cycle that remained hidden from orbital scans, alongside clues of how life may have been wiped out on the planet.

The rete ovarii, a poorly understood structure connected to the ovaries, may be much more essential to ovarian function than scientists initially thought.

A study by researchers from the University of British Columbia's Blusson Quantum Matter Institute (UBC Blusson QMI) has found a rare form of one-dimensional quantum magnetism in the metallic compound Ti4MnBi2, offering e...

In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D supe...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn't sound like a mate...

The report of possible biosignatures on the exoplanet K2-18b is exciting, but we are a long way from establishing beyond doubt that there is life on such a distant world

When Roman Egypt came under attack from the Kushites in what is now Sudan, the Roman forces responded by destroying a Kushite city - or so we thought

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some exp...

New research reveals that the vagus nerve, which helps regulate appetite, interacts with socio-economic status to influence eating behavior. In a chocolate tasting study, participants from higher socio-economic backgroun...

New global rules will see a carbon levy applied to emissions from shipping for the first time, but analysts say the package falls short of what is needed

Survivors of the 2018 Camp Fire in California exhibit long-term cognitive changes, particularly in decision-making. Participants directly exposed to the wildfire showed reduced ability to choose long-term rewards and dis...
