New insights into the potential for new classes of HIF inhibitors to restore control of the hypoxia response--representing the potential foundation of a new cancer-fighting strategy--are the focus of recently published articles in Nature and Structure featuring work by Kevin Gardner of the City University of New York's Advanced Science Research Center (CUNY ASRC).

MEDFORD/SOMERVILLE, Mass. (September 13, 2016) --Tufts University researchers have discovered a new technique for generating rapidly-differentiating human neural stem cells for use in a variety of tissue engineering applications, including a three-dimensional model of the human brain, according to a paper published today in Stem Cell Reports. The work could pave the way for experiments that engineer other innervated tissues, such as the skin and cornea, and for the development of human brain models with diseases such as Alzheimer's or Parkinson's.

When it comes to water, some materials have a split personality - and some of these materials could hold the key to new ways of harnessing solar energy.
These small assemblies of organic molecules have parts that are hydrophobic, or water-fearing, while other parts are hydrophilic, or water-loving. Because of their schizoid nature, micelles organize themselves into spheres that have their hydrophilic parts turned out while their hydrophobic parts are shielded inside.

They have found elevated levels of transglutaminase 2, or TG2, in the brains of mice experiencing chronic stress - an animal model of depression - as well as the prefrontal cortex of depressed people who committed suicide.

PHILADELPHIA - With over 120,000 patients in the United States waiting for a kidney transplant, scientists and physicians are constantly looking to expand the pool of available organs through increasing donation and optimizing allocation. Researchers from Thomas Jefferson University analyzed data from thousands of transplants and developed a scoring system for donor kidneys that they hope might expand the pool of available organs in two ways.

Hurricane Orlene reached peak strength as the Suomi NPP satellite passed overhead.
On Sept. 12 at 5 p.m. EDT Orlene's maximum sustained winds reached 110 mph (175 kph) and became a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale.
NASA-NOAA's Suomi NPP satellite passed over Orlene on Sept. 12 at 4:40 p.m. EDT (20:40 UTC). The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of the storm that showed the storm at its peak intensity with an eye surrounded by powerful thunderstorms.

Scientists at the University of Liverpool have made an important breakthrough which could lead to the design of better fuel cell materials.
In a paper published in 'Nature Communications', they demonstrate how they synthesised nanometre-sized cage molecules that can be used to transport charge in proton exchange membrane (PEM) applications.
Proton-exchange membrane fuel cells (PEMFCs) are considered to be a promising technology for clean and efficient power generation in the twenty-first century.

A new scientific study reveals one way to stop proteins from triggering an energy failure inside nerve cells during Huntington's disease. Huntington's disease is an inherited genetic disorder caused by mutations in the gene that encodes huntingtin protein. Approximately 30,000 Americans have mutant huntingtin protein which can impair energy-producing parts of nerve cells called mitochondria. The mutant protein destroys nerve cells and slowly chips away at a person's ability to walk, speak, and control their behavior.

WASHINGTON - The demand for family caregivers for adults who are 65 or older is increasing significantly, and family caregivers need more recognition, information, and support to fulfill their responsibilities and maintain their own health, financial security, and well-being, says a new report from the National Academies of Sciences, Engineering, and Medicine. Although caregivers' individual circumstances vary, family caregiving can negatively affect caregivers' mental and physical health as well cause economic harm, including loss of income and career opportunities.

Tumours are an accumulation of cells that divide without control, accumulating hundreds of chromosomal alterations and mutations in their DNA. These alterations are triggered in part by a type of damage to the DNA known as replicative stress. To survive in the face of this chaos, tumour cells need the intervention of the damage response protein ATR, known for its role as guardian of genome integrity, to which they become addicted.
