Moderate warming rewires one-third of microalga's genes, study finds
Moderate warming rewires one-third of microalga's genes, study finds
Researchers have demonstrated for the first time that the microalga Chlamydomonas reinhardtii alters the activity of about one-third of its protein-coding genes in response even to moderate temperature changes. The study, published in the journal The Plant Cell, points to far-rea
Ribosome-based gene circuit lets cells read six signals and trigger responses
Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene circuit' platform that can simultaneously read multiple
Yale scientists may have found how Parkinson's disease spreads through the brain
Yale scientists may have found how Parkinson's disease spreads through the brain
Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progression, offering a potential new target for future therapies.
Alzheimer's tau protein has a surprising secret role in memory
Alzheimer's tau protein has a surprising secret role in memory
Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the re
RNA-only repair enzyme reveals how primordial life could have protected genomes
RNA-only repair enzyme reveals how primordial life could have protected genomes
In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.
New mechanism shows how plants rapidly adapt to intense sunlight
New mechanism shows how plants rapidly adapt to intense sunlight
Plants do not wait hours to respond to intense sunlight—they react within minutes. Researchers at Bielefeld University and the Australian National University have discovered a new signaling pathway that enables plants to directly adjust their protein production before genes in th
Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates
Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates
Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists to operate the same way among birds, reptiles, amph

Mar de Azov: o conflito que ameaça uma herança gastronômica milenar
Além dos tanqueiros e drones, o Mar de Azov guarda séculos de tradição pesqueira e culinária que moldou o paladar de comunidades costeiras da Ucrânia e da Rússia.
Novo sensor detecta fibrose hepática cedo — e isso muda tudo para quem treina
Novo sensor detecta fibrose hepática cedo — e isso muda tudo para quem treina
Pesquisadores sul-coreanos criaram um biossensor capaz de identificar a fibrose do fígado em fase inicial com apenas algumas gotas de sangue. Entenda por que quem pratica esportes deve ficar de olho nessa descoberta.
