SUPER GLASS MATERIAL  ALMOST AS STRONG AS STEEL

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.

The First Patient To Be Cured Of Sickle Cell Disease

The medical breakthrough resulted when physicians at the University of Illinois Hospital & Health Science System performed a procedure using medication to suppress her immune system and a small dose of total body radiation before doing the stem cell transplant. The procedure allows for the patient’s own bone marrow to coexist with that of the donor.

Self-levitating displays: Mid-air virtual objects

An interactive swarm of flying 3D pixels (voxels) is set to revolutionize the way people interact with virtual reality. The system, called BitDrones, allows users to explore virtual 3D information by interacting with physical self-levitating building blocks

Does religion make kids less generous?

n the study, children growing up in households that weren’t religious were significantly more likely to share than were children growing up in religious homes. The findings support the notion that the secularization of moral discourse may serve to increase rather than decrease human kindness, the researchers say.

Vitamin C halts growth of aggressive forms of colorectal cancer

High levels of vitamin C kill certain kinds of colorectal cancers in cell cultures and mice, according to a new study from Weill Cornell Medicine investigators. The findings suggest that scientists could one day harness vitamin C to develop targeted treatments.

Researchers take two big steps toward quantum computing

“Spooky action at a distance,” Einstein’s famous, dismissive characterization of quantum entanglement, has long been established as a physical phenomenon, and researchers are keen to develop practical applications for entanglement including communication, encryption, and computing.

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.

Smallholders gaining from nitrogen-efficient maize

Nancy Shibona, a small-scale maize farmer from Kakamega County, Kenya, is a widow and her family’s bread winner.

Shobona grows a nitrogen-use-efficient (NUE) type of maize. The variety was developed by the Improved Maize for African Soils (IMAS) project, an alliance led by the International Maize and Wheat Improvement Center (CYMMIT).

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.
