RESEARCHERS AT THE HARVARD STEM CELL INSTITUTE have discovered a substance in the blood of young mice that reverses a major effect of aging in the hearts of old mice. The substance, called GDF-11, is an obscure member of the transforming growth factor family of proteins; it was identified by Forst family professor of stem cell and

Diabetes Breakthrough Young Tunisian researcher Najib Ben Brahim of the University of Virginia, USA, developed a new artificial pancreas device which became a breakthrough discovery to cure type 1 diabetes. This comes as the world celebrates World Diabetes Day on November 13th, 2011. Mr. Najib Ben Brahim, 24 years, is currently pursuing his PhD at

Engineers use graphene as a “copy machine” to produce cheaper semiconductor wafers. In 2016, annual global semiconductor sales reached their highest-ever point, at $339 billion worldwide. In that same year, the semiconductor industry spent about $7.2 billion worldwide on wafers that serve as the substrates for microelectronics components, which can be turned into transistors, light-emitting

Approach could bypass the time-consuming steps currently needed to test new photovoltaic materials. The worldwide quest by researchers to find better, more efficient materials for tomorrow’s solar panels is usually slow and painstaking. Researchers typically must produce lab samples — which are often composed of multiple layers of different materials bonded together — for extensive

Image via Wikipedia Researchers have found a gene that promotes faster-growing and larger roots, which could lead to plants with a robuster ability to sequester excess atmospheric carbon Changes to a single gene in a model organism in plant biology, Arabidopsis thaliana, have been found to promote faster-growing and larger root systems—an application that could help

Simon Fraser University virologist Masahiro Niikura and his doctoral student Nicole Bance are among an international group of scientists that has discovered a new class of molecular compounds capable of killing the influenza virus. Working on the premise that too much of a good thing can be a killer, the scientists have advanced previous researchers’ methods of manipulating an

In the June 2011 issue of Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of water, providing a possible solution to the problem of the world’s ever-growing population demanding more and more fresh drinking water.

EPFL chemists have developed a method that can significantly increase the yield of sugars from plants, improving the production of renewable fuels, chemicals, and materials. Producing fuels and chemicals from biomass (wood, grasses, etc.) is one of the most promising solutions for building a renewable economy. The process involves breaking down, or “deconstructing”, plants to

For the more than 1 million Americans who live with type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a Cornell-led research team has developed a device that could revolutionize management of the disease. In Type 1 diabetes, insulin-producing pancreatic cell clusters (islets) are

Researchers centered at Nagoya University develop a nanowire device able to detect microscopic levels of urinary markers potentially implicated in cancer Cells communicate with each other through a number of different mechanisms. Some of these mechanisms are well-known: in animals, for example, predatory threats can drive the release of norepinephrine, a hormone that travels through
