OU astrophysicists detect most luminous diffuse gamma-ray emission from Arp 220
An OU team has detected for the first time the most luminous gamma-ray emission from the merging galaxy Arp 220 -- the nearest ultraluminous infrared galaxy to Earth reveals the hidden extreme energetic processes in galaxies. Luminous infrared galaxies and ultraluminous infrared galaxies are the most luminous of all galaxies.

Light can 'heal' defects in new solar cell materials
Now, a team of researchers at MIT and elsewhere say they have made significant inroads toward understanding a process for improving perovskites' performance, by modifying the material using intense light. The new findings are being reported in the journal Nature Communications, in a paper by Samuel Stranks, a researcher at MIT; Vladimir Bulovic, the Fariborz Maseeh (1990) Professor of Emerging Technology and associate dean for innovation; and eight colleagues at other institutions in the US and the UK.

A history of snowfall on Greenland, hidden in ancient leaf waxes
The history of Greenland's snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the passing years. Using this ancient record, scientists have determined that snowfall at one key location in western Greenland may have intensified from 6,000 to 4,000 years ago, a period when the planet's Northern Hemisphere was warmer than it is today.

Evolution and religion: New insight into instructor attitudes in Arizona
In a first-of-its kind study, scientists from ASU School of Life Sciences have found that a majority of professors teaching biology in Arizona universities do not believe that helping students accept the theory of evolution is an instructional goal. In fact, a majority of study participants say their only goal is to help students understand evolution.

Photon collisions: Photonic billiards might be the newest game!
When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons a similar process -- the elastic collision -- has never been observed. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences have shown, however, that such a process does not only occur, but even could soon be registered in heavy ion collisions at the LHC accelerator.

Will more snow over Antarctica offset rising seas? Don't count on it
Heavier snow over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.

Scientists discover the evolutionary link between protein structure and function
A new University of Illinois study demonstrates the evolution of protein structure and function over 3.8 billion years. Snippets of genetic code, consistent across organisms and time, direct proteins to create 'loops,' or active sites that give proteins their function. The link between structure and function in proteins can be thought of as a network. Demonstrating evolution in this small-scale network may help others understand how other networks, such as the internet, change over time.
