Att träd binder koldioxid är välkänt. Men träd håller även ner temperaturen på fler sätt än många tidigare har trott. Träd släpper ifrån sig gaser och de gaserna har en nedkylande effekt på atmosfären. – Den ljuvliga doften av en tallskog är just sådana gaser, säger klimatforskaren Catherine Scott vid Leeds universitet.

Extensive global sampling and sequencing of the pandemic virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have enabled researchers to monitor its spread and to identify concerning new variants. Two important determinants of variant spread are how frequently they arise within individuals and how likely they are to be transmitted. To characterize within-host diversity and transmis

Energy implications of the 21st century agrarian transition7h
Nature Communications, Published online: 19 April 2021; doi:10.1038/s41467-021-22581-7 The global agrarian transition is characterized by a rise in large-scale land acquisitions (LSLAs), whose energy impacts are unknown. Here, the authors assess how LSLAs change land use, finding that they necessitate greater investment in energy to meet demands, and greater greenhouse gas emissions.

How scientists are 'looking' inside asteroids1h
Asteroids can pose a threat to life on Earth but are also a valuable source of resources to make fuel or water to aid deep space exploration. Devoid of geological and atmospheric processes, these space rocks provide a window onto the evolution of the solar system. But to really understand their secrets, scientists must know what's inside them.
