Liquid crystals for fast switching devices

An international team has investigated a newly synthesized liquid-crystalline material that promises applications in optoelectronics. Simple rod-shaped molecules with a single center of chirality self-assemble into helical structures at room temperatur…

Spaceflight wreaks havoc on liver metabolism

Researchers have demonstrated that microgravity and other environmental factors in space play different roles in inducing oxidative stress, which, in turn, alters the metabolism of sulfur-containing compounds in the liver of mice. The study highlighted…

Migratory birds have lighter-colored feathers

Migratory birds are specially adapted to find their way over extreme distances that represent remarkable tests of endurance. Now, researchers have discovered an unexpected way that migratory birds keep their cool during such arduous journeys: lighter-c…

Cataract surgery linked with lessened dementia risk

Based on the longitudinal data of over 3,000 study participants, researchers found that subjects who underwent cataract surgery had nearly 30% lower risk of developing dementia from any cause compared with those who did not. This lowered risk persisted…

Teaching an old chemical new tricks

Chemists have put a new spin on an old catalyst called ‘Barton’s base’ to invent a faster, ‘greener’ chemical reaction. Their new chemistry speeds up molecule synthesis used for discovering new materials and drugs.

Common Arctic finches are all the same species

New research could ruffle some feathers in the birding world. It finds that Redpolls, a bird found in the Arctic that will sometimes come to the Southern latitudes during the winter and can be hard to differentiate, aren’t actually multiple species, ge…

Big gaps in quest to sequence genomes of all animals

Efforts to sequence the genomes of the world’s animals tend to focus on those that most resemble humans with the work conducted almost entirely in the Global North, according to new analysis. Researchers warn current efforts are overlooking huge swathe…
