DNA sequencing from soil called moon landings of genomics

DNA sequencing from soil called ‘moon landings of genomics’ Prof Mikkel Winther Pedersen sampling cave sediments in Mexico. Image: Devlin A Gandy Researchers at the University of Copenhagen say their DNA sequencing of sediment from a Mexican cave heralds a new frontier for genomics. Scientists have made a major breakthrough in DNA sequencing that they have described as “the moon landings of genomics” as researchers will no longer have to use fossils to determine genetic ancestry. The group, which is based in the Lundbeck Foundation GeoGenetics Centre at the University of Copenhagen, sequenced ancient DNA from soil for the first time. They claim that the advance could transform how research is carried out in the field.

Stone Age bear genome reconstructed from DNA in Mexican cave

Date Time Stone Age bear genome reconstructed from DNA in Mexican cave Scientists have reconstructed ancient DNA from soil for the first time, in an advance that will significantly enhance the study of animal, plant and microorganism evolution. Analysis of DNA found in soil could have the potential to expand the narrative about everything from the evolution of species to developments in climate change – fossils will no longer be needed. Eske Willerslev A team of scientists led by Professor Eske Willerslev in the University of Cambridge’s Department of Zoology and the Lundbeck Foundation GeoGenetics Centre, University of Copenhagen, have recreated the genomes of animals, plants and bacteria from microscopic fragments of DNA found in the remote Chiquihuite Cave in Mexico.

Thunderstorm Asthma, Robot Overlords, T-Rex Packs and More Mysterious News Briefly — April 20, 2021

Mysterious News Briefly April 20, 2021  The most severe occurrence of “thunderstorm asthma” ever – it happened in Melbourne, Australia, in 2016 when ten people mysteriously died – has finally been explained as the result of a combination of lightning strikes, wind gusts, low humidity and popping pollen grains deep in the lungs. If you have asthma during a thunderstorm, make sure you’re not holding a metal inhaler. Astronomers have discovered a super-Earth planet orbiting GJ 740, a red dwarf star situated some 36 light years from the Earth, and its year lasts only 2.4 days. This is truly a planet where, if you don’t like the weather, wait a minute.
