Scientists found out how naturally unstable filaments decide whether to grow or to shorten.

A new study suggests that mindfulness training and/or non-invasive brain stimulation could reduce bladder leaks and feelings of urgency in patients with ‘latchkey incontinence.’

Health Secretary Robert F. Kennedy Jr. has repeatedly questioned the safety of mRNA technology, which is used in the company’s shot.The Trump administration has delivered its latest blow to vaccines, canceling a nearly $600-million contract to the drugmaker Moderna that was intended to develop a shot for humans against bird flu.The decision also forfeited the U.S. government’s right to purchase doses ahead of a pandemic, and canceled an agreement set up by the Biden administration in January to prepare the nation for a potential bird flu pandemic. The Moderna contract built on a previous government investment of $175 million last year.The move was not entirely unexpected. The Department of Health and Human Services said earlier this year that it was reviewing the contract. And Health Secretary Robert F. Kennedy Jr. has repeatedly questioned the safety of mRNA technology, which is used in Moderna’s Covid vaccine.First used for the Covid vaccines made by Pfizer-BioNTech and Moderna, mRNA shots instruct the body to produce a fragment of the virus, which then sets off the body’s immune response.Andrew Nixon, a Health and Human Services spokesman, said: “After a rigorous review, we concluded that continued investment in Moderna’s H5N1 mRNA vaccine was not scientifically or ethically justifiable.”For several years, a type of avian flu known as H5N1 has circulated around the world, killing wild birds and domestic flocks, and spreading to a range of other species including bears and sea mammals.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

The process of necrosis, a form of cell death, may represent one of the most promising ways to change the course of human aging, disease and even space travel, according to a new study.

New techniques used to analyze soft tissue in dinosaur fossils may hold the key to new cancer discoveries. Researchers have analyzed dinosaur fossils using advanced paleoproteomic techniques, a method that holds promise for uncovering molecular data from ancient specimens.

SAVANA uses a machine learning algorithm to identify cancer-specific structural variations and copy number aberrations in long-read DNA sequencing data. The complex structure of cancer genomes means that standard analysis tools give false-positive results, leading to erroneous clinical interpretations of tumour biology. SAVANA significantly reduces such errors. SAVANA offers rapid and reliable genomic analysis to better analyse clinical samples, thereby informing cancer diagnosis and therapeutic interventions.

Scientists have developed a data-driven method to accelerate the discovery of affordable, stable catalysts for clean hydrogen production. Using a digital platform called DigCat, they identified a low-cost metal oxide that performs both OER and HER in acidic conditions and remains stable over time.

Researchers have identified a monoacylglycerol acyltransferase-coding gene named bishu-1. It is involved in the thermal responsiveness of cool temperature-sensing neurons by regulating ionotropic receptor expression, thereby maintaining the cool temperature avoidance behaviors in Drosophila larvae.

Coffee can help you stay awake. But what does caffeine actually do to your brain once you’re asleep? Using AI, a team of researchers has an answer: it affects the brain’s ‘criticality’.

Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, researchers developed a new analytical method combining an asymmetric flow field-flow fractionation system and mass spectrometry to separately quantify these forms. This technique allows for better quality control and safety evaluation of metal-based nanomedicines, promoting their development and clinical use, with applications also extending to food, cosmetics, and the environment.
