3D genome study reveals molecular regulatory mechanisms of human brain evolution

A team led by Prof. SU Bing from the Kunming Institute of Zoology (KIZ) of the Chinese Academy of Sciences (CAS), Prof. LI Cheng from Peking University, and Prof. ZHANG Shihua from the Academy of Mathematics and Systems Science of CAS has reported the highest resolution by far of the 3D genome of the primate brain, and demonstrated the molecular regulatory mechanisms of human brain evolution through cross-species multi-omics analysis and experimental validation. The study was published in Cell.

New transformative pathways to build a more resilient and sustainable future

It is clear that COVID-19 has drastically changed our world, but how can we use the lessons learnt to build a more resilient and sustainable future? The International Institute for Applied Systems Analysis (IIASA) and the International Science Council (ISC) have drawn on the combined strengths and expertise of the two organizations to help find a way forward.

Viral relatives of SARS-CoV-2 can evolve to evade the human immune system

Scientists have shown that two species of seasonal human coronavirus related to SARS-CoV-2 can evolve in certain proteins to escape recognition by the immune system, according to a study published today in eLife.

Speciation process takes place in the presence of maximal gene flow, indicates study

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.

Study uncovers unusual sex chromosomes of Australian iconic animals

The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually, appear as one pair of morphologically different chromosomes between sexes.

Researchers map platypus genome to understand its bizarre characteristics

Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes.

Study shows that hemoglobin in several species descends from a single gene

The marine worm Platynereis dumerilii has enabled researchers from CNRS, Université de Paris, Sorbonne Université, University of Saint Petersburg, and the University of Rio de Janeiro to demonstrate that hemoglobin appeared independently in several species and actually evolved from a single gene transmitted to all by their last common ancestor.

Study reveals evolutionary relationship between two different organelles in liverwort cells

Cells, the basic unit of life, are surrounded by a limiting membrane called the plasma membrane. Inside cells, there are various membrane-bounded organelles, each of which has various and distinctive functions.

Scientists identify new weapon to fight against antibiotic-resistant bacteria

As scientists around the globe wage war against a novel, deadly virus, one University of Colorado Boulder lab is working on new weapons to battle a different microbial threat: a rising tide of antibiotic-resistant bacteria which, if left unchecked, could kill an estimated 10 million people annually by 2050.
