According to ancient lore, Genghis Khan instructed his horsemen to wear silk vests underneath their armor to better protect themselves against an onslaught of arrows during battle. Since the time of Khan, body armor has significantly evolved—silk has given way to ultra-hard materials that act like impenetrable walls against most ammunition. However, even this armor can fail, particularly if it is hit by high-speed ammunition or other fast-moving objects.

Researchers at Texas A&M University have formulated a new recipe that can prevent weaknesses in modern-day armor. By adding a tiny amount of the element silicon to boron carbide, a material commonly used for making body armor, they discovered that bullet-resistant gear could be made substantially more resilient to high-speed impacts.

The mutation that causes Angelman syndrome makes neurons hyperexcitable, according to a study in brain organoids and mice¹. The findings may help explain why about 90 percent of people with the syndrome experience seizures that do not respond to treatment.

Angelman syndrome is a rare genetic condition linked to autism. It is caused when the maternal copy of a gene called UBE3A is either missing or mutated. Apart from seizures, the condition is characterized by developmental delay, problems with balance and speech, and an unusually happy disposition.

The new study found that mutations in UBE3A suppress the production of proteins that keep the activity of ‘big potassium’ ion channels in check. These channels control the flow of large amounts of potassium ions passing through neurons. When the current increases in the absence of UBE3A, the neurons become exceptionally excitable.

A new Facebook algorithm could lead to safer and more efficient bots.

A group of University of Chicago scientists has uncovered a previously unknown way that our genes are made into reality.

Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed—using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design.

“It appears to be a fundamental pathway we didn’t know about. Anytime that happens, it holds promise to open up completely new directions of research and inquiry,” said Prof. Chuan He, a world-renowned chemist.
