A research team is developing a 3D-printed skin imitation equipped with living cells in order to test nanoparticles from cosmetics without animal testing.

The scent of blooming flowers and fresh plant life is not just a perk of springtime; it is a key driver in the survival and evolution of butterflies and moths. New research reveals how the daily cycles of plant aromas are linked to the dietary habits and…

An archaeological study of human settlement during the Final Palaeolithic revealed that populations in Europe did not decrease homogenously during the last cold phase of the Ice Age. Significant variation in regional population sizes indicate differentiated…

Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a new treatment for allergies.

In the fight against bacterial pathogens, researchers are combining vaccination with targeted colonization of the intestine by harmless microorganisms. This approach could potentially mark a turning point in the antibiotics crisis.

A team of researchers has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics. Their study provides the first comprehensive understanding of how mRNA vaccines are delivered, processed, and degraded within cells -- a…

Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make the study of these behaviors increasingly difficult, underscoring the…

A powerful new software platform is set to transform biomedical research by allowing scientists to conduct complex and customized data analyses without advanced programming skills. The web-based platform enables scientists to analyze and visualize their own…

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ultrasound to reveal capillaries and cells across living…

New research shows that Sat Nav systems are helping keep older drivers on the roads for longer. The study reveals that over 65s with a poorer sense of direction rely more on help from GPS navigation systems such as Sat Nav or smartphone maps. Those using GPS…

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

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

Since Darwin's time, the phenomenon known as flower constancy -- i.e., where insects consistently visit the same flower type even when many others are also present -- has been understood as a passive behavior to reduce the effort of remembering different…

Plant biologists examined records for nearly 1,200 individual corpse flower plants from 111 institutions around the world. The data and records were severely lacking and not standardized. Without complete information, conservationists were unable to make…

Scientists have developed an AI-powered fluid simulation model that significantly reduces computation time while maintaining accuracy. Their approach could aid offshore power generation, ship design and ocean monitoring.

A unique carbon capture technology could offer a more cost-effective way to remove carbon dioxide (CO2) from the air and turn it into clean, synthetic fuel.

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

Certain antibiotic-resistant infections could be treated with precision medicine in the future, thanks to a new resource mapping plasmids the ultimate vehicle of rapid bacterial evolution.

A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Conversely, an African diet rich in vegetables, fiber, and…

A new method to recycle wind turbine blades without using harsh chemicals resulted in the recovery of high-strength glass fibers and resins that allowed researchers to re-purpose the materials to create stronger plastics. The innovation provides a simple and…

Researchers have expanded the potential of carbon capture technology that plucks CO2 directly from the air by demonstrating that there are multiple suitable and abundant materials that can facilitate direct air capture. Researchers present new, lower-cost…

A new study has found that the world's finest yodellers aren't from Austria or Switzerland, but the rainforests of Latin America. The research provides significant new insights into the diverse vocal sounds of non-human primates, and reveals for the first time…

As global temperatures warm, the Southern Ocean -- between Antarctica and other continents -- will eventually release heat absorbed from the atmosphere, leading to projected long-term increases in precipitation over East Asia and the Western U.S., regardless…

When we move, it's harder for existing wearable devices to accurately track our heart activity. But researchers found that a starfish's five-arm shape helps solve this problem. Inspired by how a starfish flips itself over -- shrinking one of its arms and using…

Honey bees are dying at alarming rates across the United States. Beekeepers in the United States lost more than 55 percent of managed colonies last year. A new study supports a novel method for testing hygienic behavior that could breed more disease resistant…

An AI model trained on large amounts of genetic data can predict whether bacteria will become antibiotic-resistant. The new study shows that antibiotic resistance is more easily transmitted between genetically similar bacteria and mainly occurs in wastewater…

Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked at internal demographics and the significant impact of human…

Monitoring urban plant health traditionally requires extensive manual labor and botanical expertise, creating challenges for cities facing expanding green spaces, higher population densities, and increasing threats to plants. Now, researchers have developed…

Researchers discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae, the bacterium that causes gonorrhoea. These substances trigger a self-destruction program, which also operates in multi-resistant variants of the pathogen.

Buzzing insects may be seen as pests -- but globally, hundreds of fly species migrate over long distances, with major benefits for people and nature, new research shows.
