New Compound Switches Between Liquid and Solid States When Exposed to Light or Heat

116488_web.jpg

A research group led by Professor Mochida Tomoyuki (Kobe University Graduate School of Science) and Dr. Funasako Yusuke (Tokyo University of Science, Yamaguchi) has developed a metal-containing compound which transforms into a solid when exposed to light and returns to liquid form when heated.

Scientists Capture the Elusive Structure of Essential Digestive Enzyme

116348_web.jpg

Using a powerful combination of techniques from biophysics to mathematics, researchers have revealed new insights into the mechanism of a liver enzyme that is critical for human health. The enzyme, phenylalanine hydroxylase, turns the essential amino acid phenylalanine -- found in eggs, beef and many other foods and as an additive in diet soda -- into tyrosine, a precursor for multiple important neurotransmitters.

A Peachy Defense System for Seeds

Don't eat the core, it's poisonous: it's something parents often say to their children before they eat their first peach. Peach pits, which are hidden inside the nut-like husk, do in fact contain amygdalin, a substance which can degrade into hydrogen cyanide in the stomach.

Rice University scientists have advanced their graphene-based de-icer to serve a dual purpose. The new material still melts ice from wings and wires when conditions get too cold. But if the air is above 7 degrees Fahrenheit, ice won't form at all.

Neutrons Probe Structure of Enzyme Critical to Development of Next-Generation HIV Drugs

16-G00322_Feature_Kovalevsky_ornlStory.jpg

A team led by the Department of Energy’s Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. The multi-institutional team used neutron crystallography to uncover detailed interactions of hydrogen bonds at the enzyme’s active site, revealing a pH-induced proton ‘hopping’ mechanism that guides its activity.

Atmospheric Aerosols Can Significantly Cool Down Climate

It is possible to significantly slow down and even temporarily stop the progression of global warming by increasing the atmospheric aerosol concentration, shows a new study from the University of Eastern Finland. However, climate engineering does not remove the need to reduce greenhouse gas emissions.

Thinning Out the Carbon Capture Viscosity Problem

TOC-5.jpg

Researchers have used computer modeling to design these liquid materials so that they retain a low viscosity after sponging up carbon dioxide, based on a surprise they found in their explorations. Although the chemists still have to test the predicted liquid in the lab, being able to predict viscosity will help researchers find and design cheaper, more efficient carbon capture materials, they report in Journal of Physical Chemistry Letters.
