Week In STEM-7 Nov


To make super-strong glass, the researchers have long set their sights on alumina, an oxidized version of aluminum that happens to possess some of the strongest chemical bonds on Earth. Putting alumina in glass, the scientists hypothesized, would make the new material super robust

The resulting material contains more alumina than any other glass to date, and the researchers found it to be transparent and reflective. Most importantly, tests showed that the glass was very hard—harder than other oxidized glasses and most metals, and almost as hard as steel.

Increased meat consumption, linked to elevated kidney cancer risk

Diets high in meat may lead to an increased risk of developing renal cell carcinoma (RCC) through intake of carcinogenic compounds created by certain cooking techniques, such as barbecuing and pan-frying. As part of a new study from The University of Texas MD Anderson Cancer Center, published online this week in the journal Cancer, researchers also discovered that individuals with specific genetic mutations are more susceptible to the harmful compounds created when cooking at high temperatures.

Study links child nutrition to livestock ownership

Livestock ownership could improve nutrition by reducing the prevalence of stunting in children, a study focusing on Ethiopia, Kenya and Uganda says.   According to the researchers who conducted the study, they aimed to understand whether the prevalence of stunting, an indicator of chronic malnutrition, was low among families who owned more household animals such as cattle, sheep, goats and chickens.
