Cognitive behavioral therapy (CBT) can change the brain function of people with Tourette syndrome, said researchers at the Institut universitaire en santé mentale de Montréal and the University of Montreal at the First World Congress on Tourette Syndrome and Tic Disorders in London.


Teenagers are very familiar with the risks of smoking cigarettes but thanks to misinformation campaigns by advocates regarding marijuana, and campaigns against the poorly-named "e-cigarettes" by pharmaceutical companies selling competing smoking cessation tools like gums and patches, they are less likely to buy into advertised claims.

"Kids were really good at describing the harmful things that happen with cigarette smoking, but when we asked about other products, there was a lot of confusion," said the study's lead author, Maria Roditis, PhD, a postdoctoral scholar in adolescent health at the Stanford University School of Medicine..


Over the past week, ESA's Integral satellite has been observing an exceptional outburst of high-energy light produced by the black hole V404 Cygni that is devouring material from its stellar companion in our Milky Way galaxy, almost 8000 light-years away in the constellation Cygnus, the Swan.

Astronomers expect that galaxies grow by swallowing smaller galaxies. But the evidence is usually not easy to see -- just as the remains of the water thrown from a glass into a pond will quickly merge with the pond water, the stars in the infalling galaxy merge in with the very similar stars of the bigger galaxy leaving no trace. But now a team of astronomers led by PhD student Alessia Longobardi at the Max-Planck-Institut für extraterrestrische Physik , Garching, Germany has applied a clever observational trick to clearly show that the nearby giant elliptical galaxy Messier 87 merged with a smaller spiral galaxy in the last billion years.


New findings may help ease concerns for women with lupus who are interested in having a child. A new study concludes that most women with lupus whose disease is not very active will have a safe pregnancy. The results are to publish online June 22 in Annals of Internal Medicine.

It was previously suggested that women with lupus avoid pregnancy because of serious complications to their own health and the health of the baby. As more knowledge became available, doctors told women with lupus to wait until symptoms were under control, but until now, it was still uncertain whether this advice was right and whether pregnancy outcomes would be favorable.


In a new study published today in The Veterinary Journal, scientists from the University of Surrey warn about the numerous risks posed to racehorses from the misuse of cobalt chloride, a banned performance-enhancing agent that has been used illegally by trainers in Australia and USA. The team of researchers have uncovered that when excessive levels of the alleged performance-enhancing substance are administered to a horse, it can cause serious cardiovascular issues, potential nerve problems, thickening of the blood and thyroid toxicity. The researchers also pointed to the lack of evidence for enhanced performance in horses and human athletes.
