Talking With Your Mouth Full: The Feeding Calls of the Humpback Whale - Space.com  We have recorded humpbacks making sounds like the trumpeting of elephants, roars like lions, whistles like dolphins, clicks like the sperm whale, mooing like cows, chattering like monkeys, and several very human-like vocalizations—some even sounding like an unusual language, with exclamations like "whoops!" Although we are just beginning, we already expect its repertoire to exceed that of any other animal we have studied to date.      
Fruit breakfast Fruit and veg 'cut stroke risk'  - BBC  People who ate three to five portions (2.7 ounces) of fruit and vegetables a day cut the risk by 11% compared with those eating fewer than three, The Lancet reported. It was 26% lower for people who ate more than five servings, University of London researchers found in the study of data on more than 257,500 people. The Department of Health says five or more daily portions cuts risk of heart disease, cancer and other problems. More than 150,000 people have a stroke each year, and more than 67,000 die of them each year. the researchers suspect that potassium may be the most important factor in preventing stroke.  

Scientists Link Another Gene To Degenerative Blindness - Science Daily  Left:  This composite image is a highly magnified view of a fruit fly's eye overlaid with light-sensitive cells known as rhabdomeres, in green. Led by medical geneticist Nansi Jo Colley, scientists at the University of Wisconsin-Madison have found that a mutation in a gene that usually chaperones proteins to the rhabdomere-bearing, photosensitive regions of fruit-fly cells can lead to the eventual breakdown of vision. (Photo illustration by: Joshua Harder)  The scientists have discovered that a mutation in a common gene called calnexin can derail the light-processing activity of cells. Calnexin-found in both fruit flies and humans-functions as a cellular chaperone, ensuring that proteins "fold" or orient properly and get to the parts of the cell they need to go. It also modulates calcium levels, which is critical for proper vision. When calnexin goes awry, however, calcium levels build up and the proteins that depend on it malfunction.At a time when more than 103 genes are known to be involved with AMD and RP, the UW-Madison work could one day help doctors deliver tailor-made treatments to patients who specifically carry calnexin mutations. Because the calnexin protein and other chaperones are also present in the brain, the work can help to answer broader questions about neurodegenerative disease, Colley adds.
