Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment.

The team reports that striking changes are now occurring in many temperate lakes similar to those previously observed in the rapidly warming Arctic, although typically many decades later. The Arctic has long been considered a "bellwether" of what will eventually happen with warmer conditions farther south.
Raw milk advocates claim that unpasteurized milk cures or prevents disease, but no scientific evidence supports this notion. Testing raw milk, which has been suggested as an alternative to pasteurization, cannot ensure a product that is 100 percent safe and free of pathogens. Pasteurization remains the best way to reduce the unavoidable risk of contamination, according to the authors of a review published in the January 1, 2009 issue of Clinical Infectious Diseases which examines the dangers of drinking raw milk.
The closer scientists look at Saturn's small moon Enceladus, the more they find evidence of an active world. The most recent flybys of Enceladus made by NASA's Cassini spacecraft have provided new signs of ongoing changes on and around the moon. The latest high-resolution images of Enceladus show signs that the south polar surface changes over time.
CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), wants you to know they can use Envisat radar imagery to operationally observe oceans at high resolution so they're observing meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race. 

Based on the trajectory and speed of the boats, CLS is acquiring data over the area skippers will be sailing into slightly ahead of their arrival time in order to monitor the metocean conditions.  
Researchers have figured out why a respiratory syncytial virus vaccine used in 1966 to inoculate children against the infection instead caused severe respiratory disease and effectively stopped efforts to make a better one. The findings in Nature Medicine could restart work on effective killed-virus vaccines not only for RSV but other respiratory viruses, researchers say. They also say the new findings debunk a popular theory that the 1966 vaccine was ineffective because the formalin used to inactivate the virus disrupted critical antigens, the substances that stimulate the production of protective antibodies.
A dose of the hormone Oxytocin reduces the stress hormone Cortisol in arguing couples. In addition, Oxytocin strengthens positive behaviour, as researchers at the University of Zurich have discovered.

Various studies in recent years have shown that the hormone Oxytocin in the brain of mammals can help in regulating social behavior. Beate Ditzen from the Psychological Institute of the UZH has now, together with colleagues from the University of Zurich, examined the hormone particularly in terms of the behavior in partnerships.
