As the Mississippi Swerves, Can We Let Nature Regain Control?
Like most people during the pandemic, Alex Kolker found himself with extra time on his hands.
Disease affects blackbirds more than previously thought
When humans are ill, we tend to be less active. This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research shows that birds' activity decreases for up to three weeks when...
New battery holds promise for green energy
A chemist envisions a future where every house is powered by renewable energy stored in batteries. He has created a new battery that could have profound implications for the large-scale energy storage needed by wind and solar farms.
Discovery of new cell type in thymus
Biomedical scientists have confirmed that newly discovered cells in the thymus are just like M cells, which are mostly known for their presence in the intestinal epithelium.
Water-quality risks linked more to social factors than money
When we determine which communities are more likely to get their water from contaminated supplies, median household income is not the best measure. That's according to a recent study that found social factors -- such as low population density, high housing vacancy, disability and race -- can have a stronger...
Fossil spines reveal deep sea’s past
Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have...
Balancing biodiversity, climate change, food for a trifecta
Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
New ribozyme can make RNA molecules accessible for click chemistry in living cells
Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells.
Large herbivores keep invasive plants at bay
Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the...
