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 rhythms found in nature may all rely on a similar mechanism, allowing their period to remain independent of temperature.

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 way to accessible and expansive diagnostics.

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 scan the whole sample. This is time-consuming and expensive. Scientists have now developed an approach that allows an image of a large area to be...

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 from ages one to 46. Chemical and biomedical engineers plan to change that with a novel microneedle patch that can immediately stop bleeding...

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 cerebrospinal fluid leak, which is often treatable.

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 first indication of how common the illness is domestically.

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 researchers explored how to turn the twisting, fractal structures behind the science into jewelry with 3D printing. The jewelry shapes are based on...

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 residential green space is associated with higher birth weight and lower odds of having a small-for-gestational-age baby.

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 diesel exhaust disrupts the ability of different areas of the human brain to interact and communicate with each other.

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 rather than hours.

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.

A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been...

When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. While parallels have been drawn between quantum entanglement and the classical physics of heat, new research demonstrates the limits of this...

Under cold conditions, not only the mother plant but also the father plant can pass on its chloroplasts to the offspring.

Scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences. They fine-tuned these tools to enable effective genetic screening for modelling specific gene mutations.

Discovering new drugs has become increasingly rare for independent large pharmaceutical companies in recent times. Almost 60% of new drugs are discovered through mergers and acquisitions and drug licensing. Now, researchers shed light on the recent trends of spinouts from academia and investments in the U.S.A and Europe, foreshadowing a promising shift in the industry's interorganizational deal...

Researchers have uncovered a gene that is overexpressed in mutated IDH1. Studies in human cells and a novel mouse model both show that this gene, called ZMYND8, plays a critical role in the radiation resistance. When they knocked down the gene, the glioma cells became responsive to radiation treatment.
