CT scans of Egyptian mummy reveal new details about the death of a pivotal pharaoh
A CT scan study of the mummy of Pharaoh Seqenenre-Taa-II, an Egyptian ruler whose death eventually helped reunite the kingdom, revealed new details about how the king died. A recent paper suggests that the pharaoh died close to the battlefield and was ceremoniously executed by several people using Hyksos weapons. Additionally, the computer-processed X-rays revealed his embalmers had skillfully concealed some of the wounds, implying professional mummification of the body, despite its poor preservation.

The water surface is a fantastic place for chemical reactions
Using an advanced technique, scientists from the RIKEN Cluster for Pioneering Research have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface--what we usually call the water surface--than in the bulk of the water, even when the light has equivalent energy. This finding could help our understanding of the many important chemical and biological processes that take place at the water surface. (2021-02-15)

Janda and his team have developed experimental vaccines that have shown in rodents to blunt the deadly effects of fentanyl as well as its even more fatal cousin, carfentanil. (2021-02-04)

Study finds consensus for arming school resource officers, division on arming teachers and other staff
A new study examined public support for arming school employees. The study found consensus for arming school resource officers, but division over whether to arm teachers and nonteaching staff. The research has clear implications for policy, including the possibility that support for arming school staff may diminish over time as young people (who are less supportive) make up a larger share of voters.

Size matters: How the size of a male's weapons affects its anti-predator tactics
When males have to fight for reproductive rights, having larger weapons such as horns gives them an edge. However, this can also limit their mobility, making them more vulnerable to predators. In a recent study, scientists from Japan proved, for the first time, that males of a species adopt different anti-predator tactics--tonic immobility or escape--based on the size of their weapons, opening doors to a better understanding of the evolution of animal behaviors. (2021-01-28)

Male butterflies mark their mates with repulsive smell during sex to 'turn off' other suitors
Butterflies have evolved to produce a strongly scented chemical in their genitals that they leave behind after sex to deter other males from pursuing their women - scientists have found. Researchers discovered a chemical made in the sex glands of the males of one species of tropical butterfly is identical to a chemical produced by flowers to attract butterflies. The study published in PLOS Biology today (19 January 2021) identified a gene for the first time. (2021-01-19)

New study findings: militarizing local police does not reduce crime
New research shows that the militarization of local law enforcement through weapons, armored vehicles, combat attire, office equipment and other items provided by the Department of Defense does not reduce crime. Additionally, researchers found incomplete records and discrepancies in the federal government's tracking of surplus military equipment, or SME, issued to local law enforcement agencies. (2020-12-07)

Tear gas should be banned, researchers find; here's why
Tear gas should be banned as it is inherently indiscriminate and frequently abused when deployed against peaceful assemblies, in enclosed spaces, in excessive quantities and against vulnerable populations. It cannot distinguish between the young and the elderly, the healthy and the sick, the peaceful and the violent. Its deployment can also cause myriad health harms, including severe injuries and death. (2020-09-03)

Trapping of acetylene
Ethylene, a key feedstock in the chemical industry, often includes traces of acetylene contaminants, which need to be removed. In the journal Angewandte Chemie, researchers describe a robust and regenerable porous metal-organic framework that captures acetylene with extraordinary efficiency and selectively. Its synergistic combination of tailor-made pore sizes and chemical docking sites makes the material especially efficient, the study says. (2020-08-27)

Immunotherapy extends survival in mouse model of hard-to-treat breast cancer (video)
Immunotherapies for cancer -- treatments that prime the immune system to attack tumors -- are valuable weapons in the anti-cancer arsenal. But some cancers are more difficult to target with this strategy than others. Today, scientists report a new immunotherapy that dramatically extends the survival of mice that have triple negative breast tumors, a difficult-to-treat form of cancer. The researchers will present their results at the American Chemical Society Fall 2020 Virtual Meeting & Expo. (2020-08-17)

Mathematical modeling revealed how chitinase, a molecular monorail, obeys a one-way sign
A novel mathematical modeling method has been developed to estimate operation models of biomolecular motors from single-molecule imaging data of motion with the Bayesian inference framework. The operation mechanism of a linear molecular motor ''chitinase'', which moves one-way on a chitin chain with degrading the chain passed by, was elucidated by mathematical modeling of experimental imaging data with the method.
