The discovery, published in @NatureComms and led by Elena Monte and @marti_qc from CRAG in collaboration with the @UmeaPlantSci, shows that chloroplasts can switch on photosynthesis genes by modifying histones, clear evidence of epigenetic control in early plant development.

Did Earth’s magnetic field exist when its core was still fully liquid? A new ETH Zurich study says yes — thanks to advanced simulations showing that even a liquid core could generate a stable magnetic field. A major step in understanding our planet’s early history.

A fully liquid Earth’s core also generates a magnetic field

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably back in its early days when its inner core was fully liquid – unlike it is to...

Flossie Wong-Staal (1946 – 2020) was a Chinese-American virologist and molecular biologist.
She was the first scientist to clone HIV and determine the function of its genes, which was a major step in proving that HIV is the cause of AIDS.

Happy Birthday, Rosalind Franklin. She captured an X-ray diffraction image of DNA and stated that a helical structure was probable. Watson and Crick then created a detailed model based on her results. They initially received credit for the discovery and were awarded the Nobel Prize after her death.🧪

“Phylogenomics of Asgard archaea reveals a unique blend of prokaryotic-like horizontal transfer and eukaryotic-like gene duplication”

Phylogenomics of Asgard archaea reveals a unique blend of prokaryotic-like horizontal transfer and eukaryotic-like gene duplication.

Asgard archaea hold a pivotal position in the tree of life as the closest known relatives to eukaryotes and are therefore crucial for understanding eukaryogenesis. Earlier genomic analyses revealed th...

Plant NLR receptors mediate pathogen resistance, and so their engineering could lead to crops with broader pathogen specificity and so broader disease resistance. @nature, authors report one such attempt achieving resistance to several potyviruses. www.nature.com/articles/s41...
