Ants can adapt their chemical profile over short evolutionary periods, say biologists

Mon, 08/14/2017 - 11:22
The bodies of ants and other insects are covered with a thin, wax-like layer that protects them from desiccation and enables them to exchange information, in social insects, for instance, to differentiate between enemies and nestmates.

Researchers develop new method to more accurately measure systolic blood pressure

Mon, 08/14/2017 - 10:18
An estimated 1 in 3 U.S. adults have high blood pressure. Blood pressure levels are often assessed by using automatic blood pressure devices.

Energy drinks among youth paving way for cocaine addictions later finds new study

Mon, 08/14/2017 - 09:45
It has been found that one third of college going American students eventually end up becoming cocaine addicts or have abuse problems with alcohol or prescription medications. Further one third of all college going students between ages 21 and 24 are habitual consumers of energy drinks. A new study has linked these two behaviors and noted that students who take energy drinks on a regular basis are more likely to abuse drugs or alcohol as they grow up. The study was published in the journal Drug and Alcohol Dependence.

According to scientists, super fleas with penises that are two and half times their size, are all set to invade the British homes this soggy summer and bring with them a host of diseases. They warn that the damp weather this August following a hot spring has led to the successful breeding of these bugs.

Goldfish survive lack of oxygen for months by converting their carbs to alcohol

Mon, 08/14/2017 - 08:01
A new study has shown that goldfish and similar crucian carps can live up to five months in icy lakes with extremely low or no oxygen. Evolution of the fish has enabled them to develop a set of enzymes that can help the fish convert their carbohydrates into alcohol.

A mutation in one of the sensors that the immune system uses to detect viruses can, in rare cases, turn infections with the chickenpox virus into a life-threatening matter.

Researchers find specific type of immune cells in patients with excessive antibody production

Sat, 08/12/2017 - 06:47
The team from Instituto de Medicina Molecular Lisboa, led by Luis Graça, analyzed blood samples from Sjögren syndrome patients, an autoimmune disease that affects the mucous membranes and moisture-secreting glands of the eyes and mouth, and found that these patients have a significant increase in a specific type of immune cells called T follicular regulatory cells (Tfr).
