DNA synthesis can be used to generate true random numbers. Credit: Isabelle Benz ETH scientists have generated a huge true random number using DNAsynthesis. It is the first time that a number of this magnitude has been created by biochemical means. True random numbers are required in fields as diverse as […]

ANIMATION For the first time, researchers describe how Rho protein really stops gene expression. New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now — precisely how the copying of genetic material that, once started, is properly turned off. […]

Krebs cycle metabolites fall in energy-rich carbon feedstock. Credit: Issey Takahashi Scientists from Nagoya University have achieved a breakthrough in converting energy-deficient metabolites to a biorenewable resource thanks to a versatile catalyst. The imminent environmental crisis calls for an urgent transition to a green economy. A team of scientists at […]

The two atlases map gene expression and availability as cells differentiate into different cell types and tissues. UW Medicine researchers at the Brotman Baty Institute in Seattle have created two cell atlases that track gene expression and chromatin accessibility during the development of human cell types and tissues. An artist’s […]

Illustration of a carboxysome and enzymes. Credit: Professor Luning Liu Researchers at the University of Liverpool have unlocked new possibilities for the future development of sustainable, clean bioenergy. The study, published in Nature Communications, shows how bacterial protein ‘cages’ can be reprogrammed as nanoscale bioreactors for hydrogen production. The carboxysome is […]

TU Graz researcher Stefan Spirk has found a way to replace liquid electrolytes in redox flow batteries with vanillin. Credit: © Lunghammer – TU Graz Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is […]

Dopamine, serotonin involved in sub-second perception, cognition. In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals — dopamine and serotonin — are at work at sub-second speeds to shape how people perceive the world and take action based on their perception. The […]

Rubisco is the most abundant enzyme on the planet. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it’s central to the process of carbon fixation and is one of Earth’s oldest carbon-fixing enzymes. Researchers at UC Davis and LBNL have now discovered an alternative form […]

Flavorings combine with solvents in e-cigarettes to produce new toxic chemicals that irritate the airways, triggering reactions that can lead to breathing and heart and blood vessel problems, according to new research presented at the ‘virtual’ European Respiratory Society International Congress.[1] Sven-Eric Jordt, associate professor of anesthesiology, pharmacology, and cancer […]

Collecting tears from Broad-snouted caiman, Caiman latirostris. Credit: Arianne P. Oriá Bird and reptile tears aren’t so unlike our own, shows a new study in Frontiers in Veterinary Science. But the differences could provide insights into better ophthalmic treatments for humans and animals, as well as clues into the evolution of […]
