A new study analyzes the required climate policy actions and targets in order to limit future global temperature rise to less than 1.5°C by 2100. This level is supported by more than 100 countries worldwide, including those most vulnerable to climate change, as a safer goal than the currently agreed international aim of 2°C.

Agricultural officials who seek to detect diseases affecting the commercial swine industry may gain a new ally — a biological detection system developed by Lawrence Livermore National Laboratory (LLNL) researchers.

Grass plants can bind, uptake and transport infectious prions, according to researchers at the University of Texas Health Science Center at Houston (UTHealth). The research was published online in the latest issue of Cell Reports.

Losses of managed honey bee colonies were 23.1 percent for the 2014-2015 winter but summer losses exceeded winter numbers for the first time, making annual losses for the year 42.1 percent, according to preliminary results of the annual survey conducted by the Bee Informed Partnership (http://beeinformed.org), the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America.

Chewing, breathing, and other regular bodily functions that we undertake “without thinking” actually do require the involvement of our brain, but the question of how the brain programs such regular functions intrigues scientists. A team lead by Arlette Kolta, a professor at the University of Montreal's Faculty of Dentistry, has shown that astrocytes play a key role.

When people become severely burned, there are limited options available to repair the skin and tissue that have been affected. People must undergo painful and tedious surgery and skin transplants to repair the damaged skin and tissues. Stratatech Corp., a Madison, WI based company, has been focused on creating new treatment options for severe burns and recently developed new human skin tissue called StrataGraft that was used to heal severe burn wounds in 30 patients during a recent clinical trial.

Thawing cells in a regulated environment presents many challenges. The need to minimize variability through standardization is crucial. Whereas the science of cell freezing has become highly standardized in order to improve and retain optimal viability and function, cell thawing has been overlooked and has much to gain from similar standardization.
