Phys.org / Plant hormones in mammals challenge view of cytokinins as purely botanical

In biology, cytokinins were long considered regulators exclusive to the plant kingdom, where they control, among other things, growth and responses to stress. Until now, little research has been conducted into whether these ...

Phys.org / From birds to fish, how extreme heat causes wildlife to suffer

Like humans, wildlife is increasingly vulnerable as climate change fuels longer and more intense heat waves, disrupting feeding and breeding and, in extreme cases, proving fatal.

Phys.org / Palm oil, coconut and soybean drive more species extinction than previously thought

Oils from crops such as coconut, palm oil and soybean are used in a range of applications, from cosmetics and makeup to margarine and spreads, and from medicines to animal feed. These oil crops, as they are known, are increasingly ...

Phys.org / Molecular simulations uncover why water nanodrops spread thin on hydrophilic surfaces

Why does water roll off a duck's back but spread on clean glass? For macroscopic (millimeter-scale) drops, this behavior can be explained using continuum theory. However, when nanoscale (10–9 mm) droplets spread on surfaces, ...

Phys.org / Arabian Sea humpback whale's long-distance trip further highlights species' unique ecology

Off Oman's coast lives a small population of just over 80 Arabian Sea humpback whales (ASHWs). They are classified as endangered and are thought to be the only humpback whale population that doesn't undertake seasonal migrations ...

Phys.org / Ripple-like rings of the 'Bullseye galaxy' could be explained by dark matter

Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the Bullseye galaxy, could have emerged through the quantum behavior of particles of dark matter. Through ...
