Neuroscientists identified Nerve cells that make us itch

London, Aug 7 (ANI): Neuroscientists have long scratched their heads to solve the puzzle of itching. But now researchers have finally worked out what makes us itch. The research team, led by neuroscientist Zhou-Feng Chen and his colleagues at Washington University in St Louis, Missouri, has identified cells in the spinal cord that spring into action when an insect bite, washing powder or infection irritates our ...

Neuroscience Genes that may be involved in heroin-addiction relapse identified

Washington, Aug 7 (ANI): While studying the brains of heroin-addicted rats, scientists have identified those genes that may be involved in precipitating a relapse. Kara Kuntz-Melcavage, from Pennsylvania State University College of Medicine, USA, and colleagues have discovered a group of genes whose expression is significantly altered following exposure to drug paraphernalia after an enforced ‘cold-turkey’ period. “A number of gene expression studies have investigated changes induced ...

cancer’s growth and spread Cells responsible for bladder cancer’s spread identified

Washington, Aug 7 (ANI): John Hopkins researchers have identified a powerful set of cells in bladder tumours that appears to be primarily responsible for the cancer’s growth and spread. The researchers have long suspected that a subset of cells in cancerous tumours act much like developmentally primitive cells known as stem cells, which spur organ development early in life and remain present in nearly all the ...

eXperimental Fuel Cell Unmanned aerial system achieves flight endurance milestone

Washington, August 7 (ANI): The Naval Research Laboratory (NRL) has completed a successful flight test of the fuel cell powered XFC (eXperimental Fuel Cell) unmanned aerial system (UAS), in which the aircraft was airborne for more than six hours, which is a flight endurance milestone. NRL’s Chemistry and Tactical Electronic Warfare Divisions are developing the XFC UAS as an expendable, long endurance platform for Intelligence, Surveillance ... Full story

gene linked to Alzheimer’s identified

Washington, Aug 7 (ANI): Scientists from University of California, Irvine, have identified a new gene linked to Alzheimer’s disease. They found that the gene called TOMM40 appears twice as often in people with Alzheimer’s disease than in those without it. The study showed that having the harmful form of TOMM40 drastically increases one’s susceptibility when other risk factors - such as having a gene called ApoE-4 - ... Full story

study DNA Genes to protect against genetic alterations and diseases identified

ondon, Aug 7 (ANI): In a study on the DNA of tiny yeast, scientists have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases.Many of these genes, and their accompanying pathways, are involved in repairing mistakes in DNA replication. And the discovery of these genes by researchers at University of California, San Diego, ... Full story

Small male seahorses suffer from ’short man’ syndrome

London, Aug 7 (ANI): Small male seahorses suffer from ’short man’ syndrome, as they try to pursue the tallest females for mating, according to a study from the University of Zurich. The research was based on the courtship rituals of the big-bellied seahorse, called Hippocampus abdominalis. The males of the species are known to give birth, so researchers had assumed that the females were in charge when ... Full story

Cell on a Chip fusion of engineering and biology

The drug heparin is widely used to prevent blood from clotting in medical procedures ranging from dialysis to open-heart surgery. With a $6 billion market, it is one of the most common drugs used in hospitals today. But its widespread use belies its crude origins: more than 90 years after it was discovered, heparin is still made from pig intestines. But a new microfluidics chip, ... Full story
