London, November 3: A team of researchers from Baylor College of Medicine and Texas Children's Hospital has found that the ability of the immune system cells called T-lymphocytes to fight childhood cancer neuroblastoma can be improved with the aid of an artificial tumour-specific receptor.

Hamburg, Germany - If you don't get enough sleep at night, be sure to drink a strong cup of coffee before trying to remember important facts - otherwise your sleep-deprived mind will play tricks with your memory, according to a team of German researchers.

Hamburg - There is new evidence that a virus could be the cause of irregular heartbeat in millions of patients who otherwise exhibit no diagnosed reason for atrial or ventricular fibrillation, according to a team of German scientists.

The researchers at the Max Delbruck Center for Molecular Medicine (MDC) in Berlin say they have uncovered the first firm evidence of the molecular mechanism whereby virus infections cause cardiac arrhythmia.

Cologne, Germany - Teenagers commonly experience mood swings and are not always approachable, and this behaviour can make it hard for parents to differentiate such emotional fluctuations from genuine depression.

Experts say it's important for parents to monitor their teenager's moods and seek treatment when warranted.

Washington, Nov 2 : Being unemployed can have long-term and possibly permanent psychological effects, including low self esteem, depression and anxiety, on an individual, according to a new study.

The research team led by Arthur H. Goldsmith, the Jackson T. Stephens Professor of Economics at Washington and Lee University said that as the period of unemployment increases the effects often become chronic.

“In the first phase of unemployment, people have a benign ignorance and think it will turn out fine, that they are not going to be emotionally damaged by this, because they’ll just go out and get a job,” said Goldsmith.

Washington, Nov 2 : Frequent urination at night can help protect against bladder cancer, says a new study.

A team of Spanish and American scientists suggests direct association between the number of times people get up at night to urinate and protection against bladder cancer.

Juan Alguacil, a researcher from the University of Huelva and one of the authors, suggest that night-time is usually the period during which there is the longest time interval between urination.

“The length of time carcinogenic agents, such as those from tobacco for example, are present in the urine, constitutes an important factor towards the likelihood of developing bladder cancer,” Science Daily quoted Alguacil as saying.
