The best from the science journals: How to tackle deadly viruses and survive in extreme cold

Here are some of the most interesting research to have appeared in top science journals last week

Mammoth mysteries unveiled

Published in Nature Structural & Molecular Biology

Using cryo-electron microscopy studies, scientists have now decoded how the woolly mammoth might have survived extreme cold. They found mutations in a particular gene (TRPV3) that is associated with sensing temperature, itch, and pain. They also observed that this mutation affected the associated channels that open and close to allow ion flow into skin cells, thus making the mammoth insensitive to temperature change and helping it rule the ice age.

Welcome 3D Graphene

Published in Materials Horizons

A new 3D-printed graphene, with better mechanical properties and finer features, is here to be the game changer. Created using graphene oxide hydrogel trapped inside acrylate polymer, the lightweight graphene aerogel can be used to make batteries, sensors and even in the aerospace industry.

Hauling herpesvirus

Published in PNAS

How herpesvirus escapes our body’s defense mechanisms has puzzled scientists for a long time. Now a study has reported two proteins that help the viral DNA replicate inside the human cell and spread the infection. When the immune system tries to block the viral DNA it releases the proteins PP71 and IE1, which helps it survive. These findings can help device new therapeutic targets against herpesviruses like cytomegalovirus and Epstein-Barr virus.

Secrets in the skull

The best from the science journals: How to tackle deadly viruses and survive in extreme cold

Yet another finding to show that our body is the perfect machine in the world. Researchers have now found secret tunnels that connect the skull bone marrow and the lining of the brain. These tunnels may act as a shortcut for immune cells to reach the brain quickly during a stroke or in the case of any other brain disorder. By using specially dyed cells in mice models, they found that during a brain injury, the skull bone marrow released more immune cells to the site of injury than the conventional tibia bone marrow - the producer of immune cells.

Bionic eye

Published in Advanced Materials

By 3D printing light receptors on a hemispherical surface, scientists are heading to create a bionic eye that may soon help in correcting vision defects and even in restoring eyesight. By assembling photodetectors, photodiodes and LEDs that have high sensitivity on a hemispherical glass dome, they were able create an eye that can give a wide field of view and revolutionise bionics.
