One species, many origins

https://www.mpg.de/13917010/one-species-many-origins

A group of researchers argue that our evolutionary past must be understood as the outcome of dynamic changes in connectivity, or gene flow, between early humans scattered across Africa. Viewing past human populations as a succession of discrete branches on an evolutionary tree may be misleading, they said, because it reduces the human story to a series of “splitting times” which may be illusory.
Sure, non-Africans today have some ancestry from Neanderthals, and some have appreciable

Chemistry Nobel Prize 2021 for Benjamin List

Benjamin List, Director at the Max Planck Institute for Coal Research, is honoured with the 2021 Nobel Prize in Chemistry, together with David MacMillan from Princeton University, for their work on asymmetric catalysis. They have established for the first time that small organic molecules are suitable as mediators of chemical reactions. Previously, science assumed that only enzymes and metals, including often toxic heavy metals or expensive and rare precious metals, could accelerate chemical reactions and steer them in a desired direction. The small organic molecules that Benjamin List and Davin McMillan introduced as catalysts are particularly suitable for asymmetric synthesis. In this process, only one of two enantiomers is produced – these are molecules that are like the left and right hand, which emans they cannot be spatially aligned. Such molecules are involved in all biological processes and also play an important role as medical agents.
I’m sure others have tried it and know why it didn’t work…“

First-Ever Detection of a Mid-Infrared Flare in Sagittarius A*, the central source of the Milky Way

https://www.mpg.de/23985074/first-ever-detection-of-a-mid-infrared-flare-in-sagittarius-a-the-central-source-of-the-milky-way

Using the MIRI instrument onboard of the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive massive black hole at the heart of the Milky Way. In simultaneous radio observations, the team found a radio counterpart of the flare lagging behind in time.
Scientists aren’t 100% sure what causes flares, so they rely on models and simulations

“We fell in love with the city”

https://www.mpg.de/19155071/we-fell-in-love-with-the-city

Ludovic Vallier, who recently moved to Berlin, will set up a lab at the Max Planck Institute for Molecular Genetics (MPIMG) in September 2022. Here, he plans to focus on basic research into the stem cell biology of the liver, closely collaborating with the researchers of the MPIMG. Vallier joined the Berlin Institute of Health at the Charité (BIH) as Einstein Professor and Group Leader earlier this year.
Sure, only a small portion of these will progress to full liver disease, but nonetheless

Zoom into the dark heart of Centaurus A

Centaurus A is home to a supermassive black hole. With the Event Horizon Telescope (EHT), researchers have now zoomed into the heart of this galaxy some 13 million light years away. In the process, the team not only precisely determined the position of the black hole but also observed a gigantic jet originating there. This bundled gas stream appears to emit radiation only at its outer edges, thereby calling theoretical models into question.
“I am sure that we will soon master the improved methods needed to evaluate the new

Birds in serious decline at Lake Constance

https://www.mpg.de/13849147/dramatic-decline-of-birds-at-lake-constance

Within 30 years, the bird population around Lake Constance declined with increasing rapidity. While in 1980 around 465,000 breeding pairs were still living in the region, by 2012 the number had fallen to 345,000 – a loss of 25 percent. These are the findings of a study carried out by researchers from the Ornithological Working Group at Lake Constance and the Max Planck Institute of Animal Behavior. Bird species that were once common like the house sparrow, the common blackbird, or the common starling have dwindled particularly rapidly. The numbers of many other species are too small for survival and their habitats in the Lake Constance region are shrinking.
