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 evolution of the winged insects collectively known as Lepidoptera.

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 reactions nested in an overall shift of settlement areas towards the east.

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 breakthrough that could pave the way for more effective vaccines and RNA-based treatments.

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 urgency of targeted conservation efforts and inclusive conservation strategies. Action is needed not only for research, but also to respect our shared cultural heritage with animal species.

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 data independently through an intuitive, interactive interface.

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 organs -- something that wasn't possible before.

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 tended to drive more frequently -- suggesting that the technology helps older people maintain driving independence.

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 flower types. However, researchers have now shown via experimentation with bees that this behavior is an active strategy in which bees balance the time required for memory retrieval and moving between flowers, thereby realizing efficient foraging.

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 informed decisions about breeding their plants. Out of the plants studied, 24% were clones and 27% were offspring from closely related individuals. Low genetic diversity could lead to further endangerment and even extinction.

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 fermented foods has positive effects. This study highlights the significant impact of diet on the immune system and metabolism.

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 environmentally friendly way to recycle wind turbine blades to create useful products.

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 materials to facilitate moisture-swing to catch and then release CO2 depending on the local air's moisture content, calling it 'one of the most promising approaches for CO2 capture.'

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 how certain calls are produced. The researchers have discovered that special anatomical structures called vocal membranes allow monkeys to introduce 'voice breaks' to their calls. These have the same rapid transitions in frequency heard in Alpine yodelling, or in Tarzan's famous yell, but cover a much wider frequency range.

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 of climate mitigation efforts.

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 the others in a coordinated motion to right itself -- scientists have created a starfish-shaped wearable device that tracks heart health in real time.

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 colonies in the future.
