NBA sees rise in acts of symbolic violence, decline in acts of physical violence‎

A new analysis of NBA basketball broadcasts from 1998 to 2018 reveals a decline in acts of physical violence, such as pushing and elbowing, and a rise in acts of symbolic violence, such as shouting, trash talking, and menacing displays. Assaf Lev from the Department of Sports Therapy at Ono Academic College in Kiryat Ono, Israel, and colleagues present these findings in the open-access journal PLOS ONE on May 18.

Research team develops wood-based foam to keep buildings cooler‎

Summertime is almost here, a time when many people try to beat the heat. But running air conditioners constantly can be expensive and wasteful. Now, researchers reporting in the ACS journal Nano Letters have designed a lightweight foam made from wood-based cellulose nanocrystals that reflects sunlight, emits absorbed heat and is thermally insulating. They suggest that the material could reduce buildings' cooling energy needs by more than a third.

Discovery uncovers need for ammonia emission regulations‎

A discovery by former Carnegie Mellon Ph.D. student, Mingyi Wang, leading a large collaborative team, sheds light on one way new particles are forming in the upper troposphere. The study, published in Nature, reveals an unexpected volatile reaction between nitric acid, sulfuric acid, and ammonia, synergistically creating new particles at a rapid rate. The findings suggest that in addition to carbon dioxide, there are other compounds in need of attention and regulation.
