An innovative temperature-compensation mechanism for oscillating chemical reactions based on temperature-responsive gels has been developed. Experimental findings, alongside a detailed mathematical analysis, hint at the possibility that circadian rhyth…

By flagging disease-associated DNA biomarkers, medical professionals can make early diagnoses and provide personalized treatments, but the typical screening methods can be laborious, expensive or limited in scope. Now, a new biosensor could pave the wa…

A research team has developed a new method to produce X-ray images in color. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and sc…

A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is the leading cause of death of Americans…

A new study suggests that some patients diagnosed with behavioral-variant frontotemporal dementia (bvFTD) — an incurable condition that robs patients of the ability to control their behavior and cope with daily living — may instead have a cerebrospin…

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them.

About 13,200 men and another 2,300 women in the United States over age 50 are estimated to have VEXAS syndrome, according to a new study. Long considered a mystery illness until its genetic basis was identified in 2020, the latest findings offer the fi…

In the ‘butterfly effect,’ an insect can flap its wings and create a microscopic change in initial conditions that leads to a hurricane halfway around the world. This chaos is seen everywhere, from weather to labor markets to brain dynamics. And now re…

Rapid economic growth has pushed rare species of big carnivores to the brink of extinction, but ecologists have suggested our appetite to once again live alongside big cats is increasing.

Researchers have identified a previously unknown signaling pathway cells use to protect their DNA while it is being copied. Targeting this pathway potentially could boost the potency of cancer therapeutics, the researchers said.

A new study assessed the associations between maternal exposure to green and blue spaces during pregnancy and birth outcomes in 11 birth cohorts from nine European countries, including Spain. The results of the study indicate that proximity to resident…

A new study has shown that common levels of traffic pollution can impair human brain function in only a matter of hours. The study was the first to show in a controlled experiment using functional magnetic resonance imaging (fMRI) that exposure to dies…

Researchers attempted to identify early symptoms of Parkinson’s disease using voice data. In their study, the researchers used artificial intelligence (AI) to analyze and assess speech signals, where calculations are done and diagnoses made in seconds …

Every year, the United States spends nearly a trillion dollars fighting metallic corrosion, an electrochemical reaction that occurs when metals oxidize and begin to rust.

A camera-trap study of two ecosystems — one with pumas and one without — adds to scientists’ understanding of the many ways apex predators influence the abundance, diversity and habits of other animals, including smaller carnivores.

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study. The work solves a mystery that has long puzzled biologists.

It’s clear that chronic stress can impact our behavior, leading to problems like depression, reduced interest in things that previously brought us pleasure, even PTSD.

Scientists are drawing inspiration from plants to develop new techniques to separate and extract valuable minerals, metals and nutrients from resource-rich wastewater.
