Phys.org / Full value added tax on meat: A first step towards pricing the environmental damages caused by diets

A study from the Potsdam Institute for Climate Impact Research (PIK) in Nature Food analyzes the ecological "footprint" from diets—and policy options to counteract through price signals. EU-wide, 23% of greenhouse gas emissions ...

Phys.org / New quantum boundary discovered: Spin size determines how the Kondo effect behaves

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding how quantum spins interact ...

Phys.org / Physicists uncover hidden magnetic order in the mysterious pseudogap phase

Physicists have uncovered a link between magnetism and a mysterious phase of matter called the pseudogap, which appears in certain quantum materials just above the temperature at which they become superconducting. The findings ...

Phys.org / Austrian cow shows first case of flexible, multi-purpose tool use in cattle

In 1982, cartoonist Gary Larson published a now-iconic "Far Side" comic titled "Cow Tools." In it, a cow stands proudly beside a jumble of bizarre, useless objects that are "tools" in name only. The joke hinged on a simple ...

Phys.org / A shark's energy reserves are linked to how far it travels, suggests new study

For years, researchers have tagged sharks in the world's oceans to learn where they go, how they migrate and where they feed. While these tags have given us a wealth of data about their lives, many questions still remain. ...
