At high densities, white-tailed deer inhibit growth of trees but increase the overall diversity of smaller plant and weed species, according to a long-term study published recently. The work is published in the journal PLOS ...

We like to think that animals follow the crowd. If most of the group does something, surely the individual will copy. But what if the story is more complicated? What if the deciding factor isn't just what the majority is ...

In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called soda pop geysers, are a new and reliable Earth-based analog for scientists studying ...

Isotope analysis reveals that social status and wealth had a profound impact on diet in medieval England, showing that people from different social groups in medieval Cambridge ate markedly different food. The research, carried ...

As governments and companies race to meet climate pledges, from net-zero goals to near-term emissions cuts, Cornell researchers have developed a blockchain-based platform to improve how those commitments are recorded and ...

Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, ...

Osmotic energy, often called blue energy, is a promising way to generate sustainable electricity from the natural mixing of salt and fresh water. It exploits the voltage that arises when ions from saltwater pass through an ...

To find new ways to shield hair from heat, sunlight and air pollution, researchers in Brazil are turning to vegan-friendly ingredients for shampoos and conditioners. Published in ACS Omega, early tests show that a fruit-algae ...

A new study published in Conservation Biology shows that geotagged social media photos can significantly improve biodiversity datasets, especially in regions underrepresented in global monitoring efforts. Led by scientists ...

Extracellular vesicles (EVs) are tiny membrane-bound particles released by cells to transport proteins and other molecules to neighboring cells. Because of this natural delivery ability, EVs have attracted growing interest ...

Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. ...
