Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.

In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are porous, and commonly form in environments swept by rough storms and waves. But about 570 million years ago, in a geologic time interval called the Ediacaran period, strange-looking, soft-bodied organisms died on the seafloor, were buried in sand, and fossilized in incredible detail.

Common pollutants are disrupting energy production at the cellular level in wild seabirds, potentially affecting fitness, new research reveals. The study, published in Environment & Health, focused on Scopoli's shearwaters breeding on Linosa, a small and remote volcanic island in the Sicilian Channel. Scientists found that widespread contaminants such as mercury and certain PFAS compounds affect the function of mitochondria, tiny cellular powerhouses that generate energy for activities from flight to reproduction.

When engineers and planners design roads, bridges and dams, they rely on hydrological models intended to protect infrastructure and communities from 50- and 100-year floods. But as climate change increases the frequency and severity of floods, existing models are becoming less and less reliable, new Cornell research finds.

The river Rhine is estimated to carry between 3,000 and 4,700 metric tons of macrolitter—pieces of litter larger than 25 millimeters in size—towards the North Sea every year, according to research published in Communications Sustainability.

The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown that increasingly frequent seasonal wildland fires across the Arctic in recent years have delayed snow cover formation by at least five days and could lead to a future 18-day reduction of snow cover duration, with implications for global ecosystems.

The year that iceberg A-23A first broke away from Antarctica's Filchner Ice Shelf, Ronald Reagan was president of the United States, and the movie "Top Gun" was setting box office records. Forty years later, the massive tabular berg—one of the largest and longest-lived bergs ever tracked by scientists—is sopping with blue meltwater and on the verge of complete disintegration as it drifts in the South Atlantic between the eastern tip of South America and South Georgia island.

A research team led by Hiroshima University and Tokyo University of Agriculture and Technology have proposed a neuroendocrine mechanism in bony fish that signals ovulation from the ovaries to the brain, using the medaka fish as a model; the first step to elucidate the neural circuits for facilitation of sexual receptivity in female teleosts.

Conventional vaccine adjuvants primarily rely on molecular binding and biochemical stimulation to activate immune responses, which often leads to limited efficacy in elderly or low-responsive populations. How to introduce physical regulation into immune activation remains an open challenge.

For the first time, scientists have answered a longstanding question in cell biology about a partnership of proteins called the "KICSTOR–GATOR1 complex" which operates as a control system inside our cells, telling them when to grow and when to stop based on nutrient availability (especially amino acids).

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously thought, but also in echinoderms (invertebrates). This is one of the most notable conclusions of a study published in the journal Nature Ecology & Evolution, which expands our knowledge of the mechanisms governing genomic regulation and biological evolution.
