In a new modeling study led by Tim Lenton from University of Exeter, we found that the earliest land plants caused atmospheric O2 levels to increase above the “fire limit”, where stuff will ignite and burn. This result fits nicely with available geochemical and paleontological evidence, but previous theoretical models predicted either an earlier or a later rise of … Read More

Inspired by the Boston Science Club for Girls, the Young Academy under the Royal Danish Academy of Sciences and Letters, have initiated a new mentor program for primary schoolers called “Videnskabsklubben” (The Science Club). The Science club creates a program for enthusiastic children, who wish to explore the natural world. Junior mentors from 8th-9th grade act as junior mentors … Read More
Eva will be working on her own research project on Mg(2+)-Fe(2+) zonation in olivine minerals using X-Ray Diffraction (XRD). This may allow for reassessment of olivine minerals found on Mars’ surface. Prof. Ed Stolper will serve as advisor in this SURF project. Eva returns to Copenhagen on September 1.
Tais will present isotope evidence for a brief oxygenation episode during the Cambrian explosion of animal life 520 Myr. The event reflects a reorganization of Earth’s global biogeochemical cycles driven by faster biological pump. One explanation is that animals themselves accelerated the transport of organic matter out of the oceans and into the sediments; for example as a result of creating larger faecal pellets, … Read More
