Amino Acids in Diet could be key to Starving Cancer

The serine synthesis pathway.

Serine and glycine can be taken up by cells through neutral amino acid transporters or synthesized de novo.

Cutting out certain amino acids from the diet of mice slows tumor growth and prolongs survival, according to new research published in Nature. Researchers at the Cancer Research UK Beatson Institute and the University of Glasgow found that removing 2 non-essential amino acids – serine and glycine – from the diet of mice slowed the development of lymphoma and intestinal cancer. The researchers also found that the special diet made some cancer cells more susceptible to chemicals in cells called reactive oxygen species.

Chemotherapy and radiotherapy boost levels of these chemicals in the cells, so this research suggests a specially formulated diet could make conventional cancer treatmen...

Making Artificial Blood for Transfusions

Bioinspired Polydopamine-Coated Hemoglobin as Potential Oxygen Carrier with Antioxidant Properties

Bioinspired Polydopamine-Coated Hemoglobin as Potential Oxygen Carrier with Antioxidant Properties

Blood transfusions can save the lives of patients who have suffered major blood loss, but hospitals don’t always have enough or the right type on hand. In search of a solution, researchers have developed a promising substitute using blood’s oxygen-carrying component, hemoglobin. The in vitro study, reported in ACS’ journal Biomacromolecules, found that the modified hemoglobin was an effective oxygen carrier and also scavenged for potentially damaging free radicals.

Red blood cells are the most commonly transfused component of blood, according to the U.S. National Heart, Lung, and Blood Institute...

Degradable Electronic Components created from Corn Starch

Degradable Poly(lactic acid)/Metal–Organic Framework Nanocomposites Exhibiting Good Mechanical, Flame Retardant, and Dielectric Properties for the Fabrication of Disposable Electronics

Degradable Poly(lactic acid)/Metal–Organic Framework Nanocomposites Exhibiting Good Mechanical, Flame Retardant, and Dielectric Properties for the Fabrication of Disposable Electronics

As consumers upgrade their gadgets at an increasing pace, the amount of electronic waste we generate continues to mount. To help combat this environmental problem, researchers have modified a degradable bioplastic derived from corn starch or other natural sources for use in more eco-friendly electronic components. They report their development in ACS’ journal Industrial & Engineering Chemistry Research.

In 2014, consumers around the world discarded about 42 million metric tons of e-waste, according to a report by the United Nations University...

The Department of Mechanical Engineering of The Hong Kong Polytechnic University (PolyU) has developed a novel technology of embedding highly conductive nanostructure into semi-conductor nanofiber. The novel composite so produced has superb charge conductivity, and can therefore be widely applied, especially in environmental arena. The innovation was awarded the Gold Medal with Congratulations of the Jury at the 45th International Exhibition of Inventions of Geneva, held on 29 March to 2 April this year.

Semiconductor made into na...
