ANTI-AGING DRUG THAT KILLS OLD CELLS PASSES FIRST HUMAN TRIAL FEBRUARY 15TH 19__KRISTIN HOUSER__ FILED UNDER: HEALTH & MEDICINE PIXABAY/TAG HARTMAN-SIMKINS Cleaning House Not all damaged cells die. Some stick around as senescent cells, unable to divide but still able to produce chemical signals — and they could play a major role in the battle against aging. “It is thought that these cells and the substances they produce are involved in the process of aging,” longevity researcher Nicolas Musi from the University of Texas at Austin  told  MIT Technology Review . “The idea is that removing these cells may be beneficial to promote healthy aging and also to prevent diseases of aging.” Based on the results of a very early trial, there may be something to that theory. Doubled Up In January , Musi and his colleagues published the results of a trial in which they treated 14 patients suffering from the fatal lung ...

Mutations, drugs drive cancer by blurring growth signals Researchers control common cancer pathway in lab with pulses of light Date: August 31, 2018 Source: University of California - San Francisco Summary: Genetic mutations in a form of non-small cell lung cancer (NSCLC) may drive tumor formation by blurring cells' perception of key growth signals, according to a new laboratory study. The research could have important implications for understanding and ultimately targeting the defective mechanisms underlying many human cancers.

Credit: Tamas Lab, University of Szeged One of the most intriguing questions about the human brain is also one of the most difficult for neuroscientists to answer: What sets our brains apart from those of other animals? advertisement "We really don't understand what makes the human brain special," said Ed Lein, Ph.D., Investigator at the Allen Institute for Brain Science. "Studying the differences at the level of cells and c...

Science News from research organizations The behavior of water: Scientists find new properties of H2O Date: August 13, 2018 Source: New York University Summary: A team of scientists has uncovered new molecular properties of water -- a discovery of a phenomenon that had previously gone unnoticed.

Credit: © kondratuk / Fotolia A team of scientists has uncovered new molecular properties of water -- a discovery of a phenomenon that had previously gone unnoticed. Liquid water is known to be an excellent transporter of its own autoionization products; that is, the charged species obtained when a water molecule (H2O) is split into protons (H+) and hydroxide ions (OH?). This remarkable property of water makes it a critical component in emerging electrochemical energy production and storage technologies such as fuel cells; indeed, lif...
