A genomic study of hydrogen-producing bacteria has revealed entirely new gene clusters capable of producing large volumes of hydrogen.

New research from the University of Minnesota upends long-held understanding about how wolves, bears and cougars—three of Yellowstone National Park's most iconic carnivores—compete for prey.

Engineers at a University of Bristol spin-out company have created a new technology that can move cells without touching them, enabling critical tasks that currently require large pieces of lab equipment to be carried out on a benchtop device.

Researchers at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have discovered a new function of the DNA repair protein ATR in regulating mitochondrial homeostasis. This discovery makes a significant contribution to understanding the…

Fusarium oxysporum is a soil-borne fungal pathogen that causes a group of serious plant diseases known as Fusarium wilts. As one of the most economically important plant pathogens worldwide, it can infect hundreds of species—including major crops like…

The European catfish is the largest freshwater fish in Europe, reaching up to 2.8 meters in length and 130 kg in weight. It was first detected in Portugal in 2014. As a top predator, it has no natural enemies and exhibits high fecundity, with females capable…

The gene encoding an enzyme from a firefly, discovered at the Sorocaba campus of the Federal University of São Carlos (UFSCar) in Brazil, has given rise to a biosensor capable of detecting pH changes in mammalian cells—which could be useful, for example, in…

Scientists at Oak Ridge National Laboratory have developed the first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent signal. The technology can help researchers detect and track…

Bonobos—our closest living relatives—create complex and meaningful combinations of calls resembling the word combinations of humans.

Researchers at Karolinska Institutet have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic "barcode," they have been able to follow the cells' developmental journey and…

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first appeared is especially hard. However, ancient sediments and…

Our environment is changing rapidly, largely as a result of human activities, leading to a significant decline in biodiversity. According to researchers from the University of Victoria and the Max Planck Institute for Evolutionary Anthropology, this decline…

A team of researchers led by Dr. Kim V. Narry, director of the Center for RNA Research at the Institute for Basic Science (IBS), has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics.

Antibiotic resistance tends to stabilize over time, according to a study published in the open-access journal PLOS Pathogens by Sonja Lehtinen from the University of Lausanne, Switzerland, and colleagues.

Insects are the dominant form of animal life on our planet, providing humans and wildlife with pollination, food, and recycling services but, despite concerns about population declines, little is known about how 99% of species globally are faring.

Why do some animals solve problems while others don't? The new study from the Max Planck Institute for Evolutionary Biology, now featured on the cover of Oikos, tackles this question with an unexpected star: the wild house mouse. This research dives into how…

Spatial transcriptomics technologies opened the door for new kinds of biological measurements, allowing scientists to generate detailed maps of where genes are expressed in tissue. But most methods rely on expensive and time-intensive imaging that requires…

Oviraptorosaurs are weird dinosaurs that look a bit like flightless birds. But these ancient animals aren't just funny-looking fossils. As my team's new research published in Royal Society Open Science shows, they can help us understand how our own forelimbs…

Each day, a human adult loses on average 50 to 70 billion cells, which die from natural causes alone. New cells replace lost ones by the complex process of cell division, which relies on what scientists call molecular machines to transport chemical cargo to…

A study led by primatologist Dr. Chiara De Gregorio from the University of Warwick has found that Madagascar's singing lemurs, the indris (Indri indri), sing out of tune in infancy and improve as adults, just like a human child learning to control their voice.

Chromatin remodeling plays a vital role in gene regulation, affecting how DNA is accessed. Disruptions in this process can also lead to cancer and other diseases.

In a growing global trend, bacteria are evolving new ways to maneuver around medical treatments for a variety of infections. The rising antibiotic resistance crisis poses a significant public health threat in hospitals and other settings, with infections…

Researchers found a protein that's essential for an enterovirus to enter human cells. Although not the infamous example—that title goes to poliovirus—other enteroviruses such as enterovirus D68 can cause similar paralytic symptoms in young children.

As I sprinted across the flower-rich meadow on the eastern coast of Cyprus, I could barely see my car. The air was full of tiny black dots, pelting like bullets past me. I hauled open the car door and breathed a sigh of relief once inside. I was surrounded by…

From personalized nutrition to more sustainable supply chains, we're just beginning to unlock the potential of AI in farming and food production. And it couldn't come at a more critical time. As the global population continues to rise, so does the demand for…

Roach fish that migrate between different lakes and water courses have larger pupils and better eyesight than roach that stay in one place. The adaptation makes it easier for the red-eyed freshwater migrants to find food in murky waters, according to a large…

A predictive model suggests that seabirds and marine mammals forage in the same areas where wind potential is most significant and that their populations may be at risk if wind farms are built there.

Directive 2010/63/EU laid down restrictions on animal testing for the testing of cosmetics and their ingredients throughout the EU. Therefore, there is an intense search for alternatives to test the absorption and toxicity of nanoparticles from cosmetics such…

Planting ground cover in fields between cash crop growing seasons is an effective way to prevent farmland from losing soil carbon from erosion, a factor that's underestimated in considering the carbon sequestration potential of cover crops, according to a new…

New science shows that overfishing is eroding the sustainability of tropical coral reef fisheries in East Africa, with small-scale fishers losing out on fisheries' productivity as entire species disappear from their catch.
