The discovery of a previously overlooked site on protein molecules may solve a mystery about how proteins are able to carry out specialized functions in living cells.
Solitary weasel-like animals called tayra might look pretty harmless, but some may actually be incubators for a parasite that causes Chagas disease, a chronic, debilitating condition that is spread by insects called kissing bugs and affects more than 8 million people worldwide.
Biochemical engineers have used sequences of DNA molecules to induce shape-changing in water-based gels, demonstrating a new tactic to produce “soft” robots and “smart” medical devices that do not rely on cumbersome wires, batteries or tethers.
Scientists have published the genome sequence of Pearl millet, a drought resistant crop plant most important in arid regions in Africa and Asia. This plant is important to small and medium farmers who grow the plant without larger irrigation. Pearl millet delivers a good harvest index under drought and heat conditions when rice, maize or wheat already have no grains anymore.
The tendency of dogs to seek contact with their owners is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study. The results contribute to our knowledge of how dogs have changed during their development from wolf to household pet.
A much greater number of monarch butterflies perished in a snowstorm in March 2016 in Mexico than previously estimated, according to new research. Analysis of damage from the storm — and the ensuing salvage logging — sheds further light on the precarious state of the famed butterflies’ overwintering colonies.
Researchers have proposed a prediction that red-edge could be observed as on the Earth even on exoplanets around M-dwarfs. They pointed out that the first oxgenic photorophs are most likely to have evolved underwater to utilize visible light just like what had happened in the primordial ocean on the Earth. They examined light adaptation mechanisms of visible- and IR-radiation-using phototrophs required for adapting to land habitats and found out that IR-using phototrophs struggle to adapt to changing light condition at the boundary of water and land surface.
Natural spider silk has excellent mechanical properties. Researchers have now found a way to boost the strength of spider’s silk using graphene-based materials, paving the way for a novel class of high-performance bionic composites.
Early weaning increases aggression and stereotypic behavior in cats. Based on the study, the recommended weaning age of 12 weeks should be raised by at least two weeks. Delaying weaning is an easy and cost-efficient way of improving the quality of life of cats.
The presence of DNA in mammalian cell cytoplasm triggers an immune response by binding to a dimeric enzyme, which inserts between DNA double helices to form the “rungs” of a ladder-like structure, as an LMU team has now shown.
