Perovskite solar cells are a flexible and sustainable alternative to conventional silicon-based solar cells. Researchers were able to find -- within only a few weeks -- new organic molecules that increase the efficiency of perovskite solar cells. The team used a clever combination of artificial intelligence (AI) and automated high-throughput synthesis. Their strategy can also be applied to other areas of materials research, such as the search for new battery materials.

A research team has investigated a new combination therapy against cancer. This therapy employs systemic administration of the tissue hormone interferon-I combined with local application of Imiquimod. This combination showed promising results in topically accessible tumors like melanoma and breast cancer models: The therapy led to the death of tumor cells at the treated sites and simultaneously activated the adaptive immune system to fight even distant metastases. The results could improve the treatment of superficial tumors such as melanoma and breast cancer.

With the recent surge in popularity of weight loss drugs like Ozempic, altogether called GLP-1s, there has been renewed scientific interest in understanding how our bodies regulate muscle growth. Scientists have linked the protein BCL6 to the maintenance of muscle mass and further suggested that BCL6-boosting therapeutics could help GLP-1 users retain muscle while losing fat. Similar therapies could also be used to treat other populations prone to muscle loss, such as older adults and patients with systemic diseases like sepsis or cancer.

Shallow coastal waters are hotspots for methane emissions, releasing significant amounts of this potent greenhouse gas into the atmosphere and contributing to global warming. This new research highlights how tides, seasons, and ocean currents strongly influence methane emissions and how tiny microorganisms, called methanotrophs, help reduce their impact.

Several hundred bees in rural Pennsylvania and rural New York are sporting tiny QR codes on their backs to track when they go in and out of their hives. The work, a collaboration among entomologists and electrical engineers, is the first step in solving a long-standing mystery of how far bees travel from their hives to collect pollen and nectar.

Electrical engineers have developed a better way to perform the comparative analysis of entire genomes. This approach can be used to study relationships between different species across geological time scales. This new approach is poised to unlock discoveries regarding how evolution has shaped present-day genomes and also how the tree of life is organized.

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough sperm and are infertile.

A single gene that regulates testosterone levels in a 'crazy' species of shore bird controls the development of three wildly different types of males, a new study has found. Ruffs have long fascinated scientists for their three types of males, known as morphs, that differ radically from each other in appearance and mating behaviors. A new study has shown that these morphs are produced by a super enzyme (HSD17B2) in the blood of the birds that's able to regulate testosterone levels in males and rapidly break down the hormone normally associated with male dominance and aggression.

A team has identified a strain of bacteria that can break down and transform at least three types of PFAS, and, perhaps even more crucially, some of the toxic byproducts of the bond-breaking process.

Our bodies are made up of around 75 billion cells. But what function does each individual cell perform and how greatly do a healthy person's cells differ from those of someone with a disease? To draw conclusions, enormous quantities of data must be analyzed and interpreted. For this purpose, machine learning methods are applied. Researchers have now tested self-supervised learning as a promising approach for testing 20 million cells or more.

The prevalence of diagnosed disorders from recurrent use of sedative, hypnotic and anti-anxiety medications in adolescents and young adults has increased sharply since 2001, according to researchers. Their study examined diagnoses of these disorders in adolescents and young adults between 2001 to 2019.

Researchers have derived a formula for viral behavior in the Wild Cards, a science fiction series written by a collection of authors about an alien virus called the Wild Card that mutates human DNA. The formula he derived is a Lagrangian formulation, which considers the different ways a system can evolve. It's also a fundamental physics principle, which also makes the fictional example a powerful teaching tool.

The remains of the earliest dinosaurs may lie undiscovered in the Amazon and other equatorial regions of South America and Africa, suggests a new study.

Researchers have found that a newly developed diet inspired by the eating habits of non-industrialized societies can significantly reduce the risk of a number of chronic diseases -- and are to share recipes with the public.

A research team has uncovered the molecular mechanism behind the remarkable underwater adhesion of hairy mussels. Their findings reveal an oxidation-independent adhesion process driven by interactions between EGF/EGF-like domains and GlcNAc-based biopolymers.

The fossilized neck bone of a flying reptile unearthed in Canada shows tell-tale signs of being bitten by a crocodile-like creature 76 million years ago, according to a new study.

Adults who have been diagnosed with attention deficit hyperactivity disorder (ADHD) may be living shorter lives than they should, finds a new study.

An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.

130 years after a fungus-eating plant received its name, a researcher has uncovered the purpose of the structure that inspired its name -- revealing a novel mechanism by which plants ensure reproduction.

New research looked at how cancers arise in children who are predisposed to developing the childhood kidney cancer, Wilms tumor, which could help anticipate the development of tumors before they fully form.
