Environmental DNA uncovers a 2-million-year-old ecosystem in Greenland

Dec. 7, 2022 - 
Around 2 million years ago, climate in Greenland resembled the forecast of a future under global warming: with trees such as poplars and birch and animals like hare, lemmings, mastodons and reindeer. Paleoclimatic records show strong polar amplification with annual temperatures of 11–19 degrees Celsius above current values. The biological communities inhabiting the Arctic during this time...

Improving precision of pressure determination in nanosecond X-ray diffraction experiments

Dec. 5, 2022 - 
X-ray diffraction measurements under laser-driven dynamic compression allow researchers to investigate the atomic structure of matter at hundreds of thousands of atmospheres of pressure and temperatures of thousands of degrees, with broad implications for condensed matter physics, planetary science and astronomy. Pressure determination in these experiments often relies on velocimetry...

New analysis helps reconcile differences between satellites and climate models

Nov. 21, 2022 - 
Satellite observations and computer simulations are important tools for understanding past changes in Earth’s climate and for projecting future changes.
