Got milk? Weightlifters will want to raise a glass after a new study found that milk protein is significantly better than soy at building muscle mass.

The study, conducted by a team of researchers at McMaster University’s Department of Kinesiology, was recently published in the American Journal of Clinical Nutrition. It compared how much muscle protein young men gained after completing a heavy weight workout followed by consumption of equivalent amounts of protein as either fluid skim milk or a soy drink.

Using a trio of space observatories, astronomers may have cracked a 45-year old mystery surrounding two ghostly spiral arms in the galaxy M106 (NGC 4258).

The results, obtained by a team from the University of Maryland (USA), took advantage of the unique capabilities of the European Space Agency’s XMM-Newton X-ray observatory, NASA’s Chandra X-ray Observatory, and NASA’s Spitzer Space Telescope.

Marine scientists recently published a research paper in the science journal, biology letters, that found humpback whales migrate over 5,100 miles from Central America to their feeding grounds off Antarctica; a record distance undertaken by any mammal.

Kristin Rasmussen, a biologist with Cascadia Research Collective, and lead author in the study, finds the record-breaking migration interesting, but is most pleased that the study validates a long held assumption that humpback whales travel to warm water areas during the winter.

In the first nationally representative study to examine the relationship between survey measures of household firearm ownership and state level rates of suicide in the U.S., researchers at the Harvard School of Public Health (HSPH) found that suicide rates among children, women and men of all ages are higher in states where more households have guns. The study appears in the April 2007 issue of The Journal of Trauma.

"We found that where there are more guns, there are more suicides," said Matthew Miller, Assistant Professor of Health Policy and Management at HSPH and lead author of the study.

People watching the Super Bowl who saw how much they had already eaten -- in this case, leftover chicken-wing bones -- ate 27 percent less than people who had no such environmental cues, finds a new Cornell study.

The difference between the two groups -- those eating at a table where leftover bones accumulated compared with those whose leftovers were removed -- was greater for men than for women.

"The results suggest that people restrict their consumption when evidence of food consumed is available to signal how much food they have eaten," said Brian Wansink, the John S.

Society’s disapproval of alcohol, tobacco and gambling means that some investors -- mostly public institutions -- lose out while other investors gain on these undervalued “sin stocks,” according to a study conducted by the Sauder School of Business at the University of British Columbia.

Sauder Prof. Marcin Kacperczyk and co-author Prof. Harrison Hong of Princeton University analyzed stock markets and the impact they feel from society’s framework of morals, traditions and laws.
