Stem Cells May Look Malignant, Not Act It

November 22, 2017

Call it the cellular equivalent of big glasses, a funny nose and a fake mustache. Bone marrow stem cells attracted to the site of a cancerous growth frequently take on the outward appearance of the malignant cells around them, University of Florida researchers report in a paper to be published in the August issue of Stem Cells. But whether that enables them to fuel cancer's ability to develop and then spread, as some scientists suspect, is not entirely clear. The findings, available early in thi...

Healthy Adults May Need Less Sleep As They Age According To Study

November 21, 2017

A study in the Feb. 1 issue of the journal SLEEP suggests that healthy older adults without sleep disorders can expect to have a reduced "sleep need" and to be less sleepy during the day than healthy young adults. Results show that during a night of eight hours in bed, total sleep time decreased significantly and progressively with age. Older adults slept about 20 minutes less than middle-aged adults, who slept 23 minutes less than young adults. The number of awakenings and the amount of time s...

New Clues On How To Treat Diseases Such As Depression And Schizophrenia

November 20, 2017

Regret has long been viewed as an exclusively human thought, one which helps prevent us from repeating bad choices but becomes debilitating when it triggers obsessive thoughts about past actions. Now a new study by Yale University researchers shows that monkeys also can be Monday morning quarterbacks and visualize alternative, hypothetical outcomes. The findings, reported in the May 26 issue of the journal Neuron, pinpoint areas of the brain where this process takes place and may give scientist...

Creation Of A New Material Capable Of Eliminating Pollutants By The Hydrocarbon Industry

November 19, 2017

A research team of the University of Granada has managed to produce the most useful material to date to eliminate pollutants such as benzene, toluene and xylene, organic solvents widely used in the hydrocarbon industry and generated by road traffic in cities. The world-wide problem of the exposure to aromatic hydrocarbons has mainly focused its attention on benzene, which is considered to be harmful to health, even in low concentrations. This material is a monolithic carbon aerogel with the adv...

Mosquitoes Can't Spot A Spermless Mate - New Target To Prevent The Spread Of Malaria By Interfering With The Mosquitoes' Ability To Reproduce

November 18, 2017

A female mosquito cannot tell if the male that she has mated with is fertile or 'spermless' and unable to fertilise her eggs, according to a new study from scientists at Imperial College London. The research, published today in the journal Proceedings of the National Academy of Sciences, could help scientists in their mission to prevent the spread of malaria by interfering with the mosquitoes' ability to reproduce. Malaria is a debilitating disease that affects more than 300 million people eve...
