Study lays groundwork for building consensus on successful aging

Scholars have long debated what successful aging is, how to measure it, and how to promote it. But the latest issue of The Gerontologist lays the groundwork for building consensus on the topic -- while pointing out that the answer may differ among academics and the general public, as well as across populations and demographic groups.

Researchers develop novel strategy in fight against cancer

A team of researchers led by Associate Professor Caroline Lee from the Yong Loo Lin School of Medicine at the National University of Singapore, in collaboration with Associate Professor Song Jianxing of the Department of Biological Sciences at the NUS Faculty of Science, has developed a novel strategy in the fight against cancer.

Scientists find seven new genes that can cause X-linked intellectual disability

X-linked intellectual disability is a disorder that predominantly affects men and can have highly variable clinical manifestations. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have found seven new genes that can cause this genetic disease: Mutations of these genes on the X chromosome lead to various forms of intellectual disability.

Researcher uses Gene Rank technique to capture, describe gene connectivity

Using the technique known as "Gene Rank" (GR), Dartmouth's Norris Cotton Cancer Center investigator Eugene Demidenko, PhD, captured and described a new characterization of gene connectivity in "Microarray Enriched Gene Rank," published in BioData Mining. The effective computer algorithm can be used to compare tissues across or within organisms at great speed with a simple laptop computer.

Study finds link between type 2 diabetes and reduction of certain cognitive abilities

Type 2 diabetes is associated with worse performance on cognitive tests measuring abilities involved in the control of emotions, behaviours and thought, says a new study from the University of Waterloo.

Study: Ebola transmission from deceased patients may be possible

To determine how long Ebola virus could remain infectious in a body after death, National Institutes of Health scientists sampled deceased Ebola-infected monkeys and discovered the virus remained viable for at least seven days. They also detected non-infectious viral RNA for up to 70 days post-mortem. The study, published in Emerging Infectious Diseases, suggests that Ebola transmission from deceased individuals may be possible for an extended period of time following death, underscoring the importance of using safe practices for handling corpses.

Researchers identify two cell-signaling molecules that appear critical to stalling cancer's spread

In what is believed to be the largest epigenetic analysis to date of cell-signaling molecules in early-stage melanoma, researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center have identified two tiny bits of non-coding genetic material in primary tumors that appear critical to stalling the cancer's spread -- and essentially setting the biological fate of the disease.

OUP announces launch of new journal that focuses on worker aging and retirement

Oxford University Press is pleased to announce the launch of a new interdisciplinary journal, Work, Aging and Retirement, which is published in association with Lingnan (University) College of Sun Yat-sen University.

New Penn Medicine study reveals how sleep deprivation increases intake of fat

Experts have warned for years that insufficient sleep can lead to weight gain. A new Penn Medicine study found that not only do we consume more food following a night of total sleep deprivation, but we also we consume more fat and less carbohydrates and a region of the brain known as the salience network is what may lead us to eat more fat.

UT Southwestern researchers identify common signaling mechanism that controls immune system

UT Southwestern Medical Center researchers have identified a common signaling mechanism to produce interferon - one of the main proteins used to signal the immune system when the body needs to defend itself against a virus, tumor, or other diseases.

A*STAR's GIS scientists develop new system that can predict treatment targets for cancer

In recent months, several national initiatives for personalized medicine have been announced, including the recently launched precision medicine initiative in the US, driven by rapid advances in genomic technologies and with the promise of cheaper and better healthcare. Significant challenges remain, however, in the management and analysis of genetic information and their integration with patient data.

Declarative memory helps individuals with neurodevelopmental disorders compensate for dysfunction

Individuals with five neurodevelopmental disorders -- autism spectrum disorder, obsessive-compulsive disorder, Tourette syndrome, dyslexia, and Specific Language Impairment -- appear to compensate for dysfunction by relying on a single powerful and nimble system in the brain known as declarative memory.

Background noise in the brain shapes neuron growth

A process previously thought to be mere background noise in the brain has been found to shape the growth of neurons as the brain develops, according to research from the MRC Centre for Developmental Neurobiology (MRC CDN), Institute of Psychiatry, Psychology & Neuroscience (IoPPN), published in Cell Reports.
