Much like our fight-or-flight response, our cells also have a stress autopilot mode. An oxygen dropoff, overheating, or an invading toxin can trigger the cellular stress response - a cascade of molecular changes that are the cell's last-ditch effort to survive.

NEW YORK, January 24, 2019 - Solar rays are a plentiful, clean source of energy that is becoming increasingly important as the world works to shift away from power sources that contribute to global warming. But current methods of harvesting solar charges are expensive and inefficient--with a theoretical efficiency limit of 33 percent. New nanomaterials developed by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York (CUNY) could provide a pathway to more efficient and potentially affordable harvesting of solar energy.

Collaborative research led by the University of East Anglia has identified one of the causes of recent deaths in UK European brown hare populations.
Working together with diagnostic laboratories in England, Scotland and Germany, the first UK cases of rabbit haemorrhagic disease virus type 2 (RHDV2) have been detected in dead hares found in two locations - Essex and Dorset.

Russian scientists have developed a new method for synthesizing para-carboxyplenylsiloxanes, a unique class of organosilicon compounds. The resulting compounds are promising for creating self-healing, electrically conductive, heat- and frost-resistant silicones.

A team of scientists from I.M. Sechenov First Moscow State Medical University (MSMU) discovered that earthworms efficiently process rice straw and enrich the soil with organic matter increasing its fertility and preventing the burning of the straw that takes quite long to naturally decompose. The results of the study were published in the European Journal of Soil Biology. The work was supported with a grant of the Russian Science Foundation.

Rockville, Md. (January 24, 2019)--Lower-than-normal zinc levels may contribute to high blood pressure (hypertension) by altering the way the kidneys handle sodium. The study is published ahead of print in the American Journal of Physiology--Renal Physiology.

Researchers from Higher School of Economics analyzed 62 million public posts on the most popular Russian social networking site VK and found that both men and women mention sons more often than daughters. They also found that posts featuring sons receive 1.5 times more likes. The results have been published in the Proceedings of the National Academy of Sciences of the United States of America.

Designating relatively small parcels of land as protected areas for wildlife with no habitat management -- which has frequently been done in urban-suburban locales around the world -- likely does not benefit declining songbird species, according to a team of researchers who studied a long-protected northeastern virgin forest plot.

While coral reefs worldwide are suffering severe damage due to global warming and ocean acidification, there is one place in the world where they are surviving these harsh conditions - the Gulf of Aqaba in the Red Sea.

In the animal kingdom, food access is among the biggest drivers of habitat preference. It influences, among other things, how animals interact, where they roam and the amount of energy they expend to maintain their access to food. But how do different members of ecologically similar species manage to live close to each other?
