The body defends itself against pathogens by depriving them of vital iron. However, this strategy doesn't always succeed against Salmonella. Researchers have discovered that these bacteria specifically target iron-rich regions within immune cells to replicate. Their findings on how pathogens evade the immune defense are important for fighting infections.

People have assumed climate change solutions that sequester carbon from the air into soils will also benefit crop yields. But a new study finds that most regenerative farming practices to build soil organic carbon -- such as planting cover crops, leaving stems and leaves on the ground and not tilling -- actually reduce yields in many situations.

New research reveals mountain glaciers across the globe will not recover for centuries -- even if human intervention cools the planet back to the 1.5 C limit, having exceeded it.

Fertilizer might be stronger than we thought. A new international study found that fertilizer can help plants survive short-term periods of extreme drought, findings which could have implications for agriculture and food systems in a world facing climate stressors.

Underwater or aerial vehicles with dimples like golf balls could be more efficient and maneuverable, a new prototype has demonstrated.

Researchers have shown that the evolution of a family of exported proteins in the malaria-causing parasite Plasmodium falciparum enabled it to infect humans.

The demand for the widely used cancer drug Taxol is increasing, but it's difficult and expensive to produce because it hasn't been possible to do it biosynthetically. Until now, that is. Researchers have now cracked the last part of a code that science has struggled with for 30 years. The breakthrough could halve the price of the drug and make production far more sustainable.

A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the stepwise neofunctionalization of a membrane fusion protein called VAMP7.

A team was able to show that swimming movements are possible even without a central control unit. This not only explains the behavior of microorganisms, it could also enable nanobots to move in a targeted manner, for example to transport drugs to the right place in the body.

Researchers have discovered a new way to reduce obesity. Supplying the gut with extra acetate reduces fat and liver mass in both normal and obese mice, as long as bacteria of the Bacteroides species is also present. When both these conditions are met, gut bacteria can eliminate more sugars from the gut and promote the burning of fats for energy in the host.

Nanoplastics are everywhere. These fragments are so tiny they can accumulate on bacteria and be taken up by plant roots; they're in our food, our water, and our bodies. Scientists don't know the full extent of their impacts on our health, but new research suggests certain nanoplastics may make foodborne pathogens more virulent.

A hidden link between impulsivity and obesity may not be fixed in human biology but shaped by the cities we live in. Using a novel engineering-based approach, researchers found that attention-deficit/hyperactivity disorder (ADHD) contributes to obesity not only directly through known biological pathways but also indirectly, by reducing physical activity.

The near-bottom water on the U.S. Northeast continental shelf provides a critical cold-water habitat for the rich regional marine ecosystem. This 'cold pool' preserves winter temperatures, even when waters elsewhere become too warm or salty during the summer. The U.S. Northeast coastal ocean has experienced accelerated warming in recent years, compared to the global average. Now, scientists using salt as a tracer are investigating how much the influx of salty offshore water onto the continental shelf contributes to the observed 'erosion' of the seasonal cold pool. This paper provides the first evidence for a seasonal salinification of the cold pool on the US Northeast continental shelf, as consistently observed in the multi-year mooring record of the [Ocean Observatories Initiative] Coastal Pioneer Array.

Animal abduction: Biologists documented five male capuchin monkeys carrying at least eleven different infant howler monkeys -- a behavior never before seen in wild primates. Rise and spread: The sightings were remotely recorded by over 85 camera traps, which allowed scientists to pinpoint the origin and subsequent spread of this social tradition over a 15-month period.

Researchers have shown that mice use chemical cues, including odors, to detect the social rank of an unfamiliar mouse and compare it to their own, using this information to determine their behavior.

A new AI decision making tool effectively balances various complex trade-offs to recommend ways of maximizing carbon storage, minimizing economic disruptions and helping improve the environment and people's everyday lives. It uses evolutionary AI, a kind of digital version of biological natural selection, to optimize policies in the face of competing priorities.

New research has revealed that high densities of European honey bees could be harming Australian native bees' 'fitness' by reducing their reproductive success and altering key traits linked to survival.

Newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing a virus from spreading through the bacterial population.

A new study reveals that heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata) -- a foundational species in Caribbean reef ecosystems -- from the devastating impacts of marine heatwaves and coral bleaching.

New research suggests that the negative effects of the ozone hole on the carbon uptake of the Southern Ocean are reversible, but only if greenhouse gas emissions rapidly decrease. The study finds that as the ozone hole heals, its influence on the ocean carbon sink of the Southern Ocean will diminish, while the influence of greenhouse gas (GHG) emissions will rise.
