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.

Imagine a world where industrial waste isn't just reduced, it's turned into something useful. This kind of circular economy is already in the works for carbon. Now, researchers in energy, environmental & chemical engineering at Washington University in St. Louis have developed a promising pathway to convert harmful nitric oxide, a key component of acid rain, into valuable nitric acid, which is used in everyday applications from fertilizer production to metal processing. The new approach converts nitrogen waste into valuable chemical product.

A new study shows how common gut bacteria can metabolize certain oral medications that target cellular receptors called GPCRs, potentially rendering these important drugs less effective.

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.

By analyzing the flowerpot snake's unique genome, scientists are uncovering how the tiny reptile repairs its DNA and prevents harmful mutations. The findings provides valuable insights into genetic repair mechanisms that could deepen our understanding of human gene evolution.

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.

Scientists should experiment with creative ways of communicating their work to inspire action to protect the natural world, researchers say.

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.

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 treatment plants and inside the human body.

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 interactions. The model identified potential societal outcomes based on demographic changes, emphasising aspects such as migration rates, cultural assimilation and the role of mortality in these transitions. The researchers aim to further develop their model with the aim of making it a standard tool for studying historical demographic interactions.
