Cherned up to the maximum

Crystals of PdGa can be grown with two distinctstructural chiralities (left and right column). The two enantiomers have mirrored crystalstructures (second row), as seen in electron-reflection patterns (third row). Schröter et al. nowdemonstrate that the handedness are reflected as well in the structure of the Fermi surfaces(bottom row), which determine the electronic behaviour of the…

Advanced technology sheds new light on evolution of teeth

Socio-economic, environmental impacts of COVID-19 quantified

Global greenhouse gas emissions, incorporating data for 2020 calculated from this study. Credit: University of Sydney The first comprehensive study of the pandemic shows consumption losses amount to more than US$3.8 trillion, triggering full-time equivalent job losses of 147 million and the biggest-ever drop in greenhouse gas emissions. The international group of researchers, using a…

Dissecting fruit flies’ varying responses to life-extension diet

A cartoon of an elderly fruit-fly enjoying his breakfast. The effects of calorie-restricted diets on fruit fly aging and lifespans is not uniform across different strains. A new study looks at small molecules involved in cell metabolism to see why this inconsistency occurs. Credit: Alice C. Gray Changes in a few small molecules involved in…
