A new study shows how neurochemicals can influence blood vessels. The findings may change how researchers interpret results from functional magnetic resonance imaging studies.

Water pollution from dyes used in textile, food, cosmetic and other manufacturing is a major ecological concern with industry and scientists seeking biocompatible and more sustainable alternatives to protect the environment. A new study has discovered a novel way to degrade and potentially remove toxic organic chemicals including azo dyes from wastewater, using a chemical photocatalysis process powered by ultraviolet light.

A research team has discovered the key role that the APOBEC3A and APOBEC3B enzymes play in driving cancer mutations by modifying the DNA in tumor genomes, offering potential new targets for intervention strategies.

Imaging being able to wear clothes that charge your gadgets just by wearing them. New research has brought us a step closer to achieving this reality.

A new study in people undergoing surgery to treat seizures related to epilepsy shows that pauses in speech reveal information about how people's brains plan and produce speech.

The development of anxiety in girls and young women may stem from an imbalance between two crucial brain chemicals, gamma-aminobutyric acid (GABA) and glutamate, according to a new study. This discovery offers promising insights into potential treatment avenues for girls and women dealing with anxiety.

In nerve cells, the hormone regulates whether mitochondria are shut down or kept running.

In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.

In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.

Simulated effects of microgravity, created by 60 days of constant bed rest, severely disrupts rhythmic gene expression in humans, according to a new study.

When plastic ends up in the ocean, it gradually weathers and disintegrates into small particles. If marine animals ingest these particles, their health can be severely affected. Large accumulations of plastic can therefore disrupt the biological balance of marine ecosystems. But which areas are particularly affected?

Researchers have developed a new, interpretable artificial intelligence (AI) model to predict 5-year breast cancer risk from mammograms, according to a new study.

Researchers have discovered that the mere act of attaching their microparticle 'backpacks' to neutrophils is enough to activate them against cancer -- no drugs needed. In experiments, backpack-bearing neutrophils shrank tumors and extended the survival of mice with cancer, and treated animals retained an immune memory of the disease. This approach opens the door to a new class of drug-free immunotherapy for cancer.

In a series of trials involving trained distance runners, researchers found that ingesting a cranberry supplement for 28 consecutive days led to noticeable improvements in both performance and muscle fatigue following 1,500-metre time trials. Reoxygenation rates were faster and running speeds improved by 1.5 per cent. The researchers found that 28 days of cranberry extract consumption by elite level endurance runners demonstrated a trend toward increased speed in 1,500-metre time trials but not in 400-metre ones.

Human sweat contains a protein that may protect against Lyme disease. About one-third of the population carries a genetic variant of this protein that is associated with Lyme disease in genome-wide association studies.

By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system. Researchers demonstrate the efficacy of ultrasound technology to detect low-amplitude movements produced by vocalizations at the surface of the chest. They also demonstrated the possibility of using the airborne ultrasound surface... Читать дальше...
