Tiny protein targets Bax, inhibits apoptosis
Researchers at The Burnham Institute have found that humanin, a small, 24-amino acid protein recently discovered in studies of Alzheimer’s Disease, suppresses activation of the protein Bax. Bax triggers pathologic cell death in a number of diseases, including Parkinson’s, stroke, heart attack and degeneration of ovaries during menopause. These results, to be published later this month in the journal Nature (currently available at the journal’s website), suggest a novel target for therapeutic design based on inhibiting the cell destructive activity of Bax.
Bax protein is known to promote the cell death program (also known as apoptosis) latent in all cells. It does so by attacking the cell’s powerhouse, called “mitochondria”, resulting in the cell’s demise. Apoptosis is critical for normal development and maintaining cell balance. Many diseases are identified with malfunction of apoptosis: too much cell death is associated with degenerative diseases of the nervous system, stroke and heart attack; failure to activate the cell death program is one of the hallmarks of cancer.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
