Warm winter disturbs hibernating animals
Submitted by Jessica on Fri, 02/03/2012 - 10:10am. YES | BioFuels and EnergyYou might not know this about me but I have a Black Labrador Retriever named Ninja. One of his most favorite things to do is chase squirrels in the park on his daily walks. Usually at this time of year he starts to get fat because there aren't many squirrels to chase, but since this winter has had such mild temperatures he's been getting thisclose to catching himself quite a few furry friends. So yesterday morning I started thinking about what these mild temperatures might mean for all the hibernating, or dormant, species come spring time. Will Ninja have more squirrel friends to chase because they'll start mating earlier? What if it gets really cold again and there's another frost? The squirrels' food sources might die and then they could starve to death...or start dining alfresco more often from the dumpsters in the alleys.
Climatologists, scientists who study weather patterns and their effect on the ecosystem, say that this warmer weather trend is likely to continue into April and it could very well effect food sources and hibernation patterns. In fact, Black Bears are expected to come out of hibernation in a few weeks, earlier than when their internal alarm tends to go off in March. When they wake up their fat reserves will have been depleted and they'll be really hungry. Most of their diet is plant based, so since there isn't a ton growing right now (as there would be more in March) they'll be searching around human generated food sources, like bird feeders or garbage bins.

Submitted by Lady Gywanna on Tue, 01/31/2012 - 4:33pm. Plant BioChemistryYogurt is nutritionally rich in protein, calcium, and riboflavin, vitamin B6 and vitamin B12 It has nutritional benefits beyond those of milk. People who are moderately lactose-intolerant can consume yogurt without ill effects, because much of the lactose in the milk precursor is converted to lactic acid by the bacterial culture. Yogurt containing live cultures is sometimes used in an attempt to prevent antibiotic-associated diarrhea
Yogurt contains varying amounts of fat. There is non-fat (0% fat), low-fat (usually 2% fat) and plain or whole milk yogurt (4% fat). A study published in the International Journal of Obesity January 11, 2005, found that the consumption of low-fat yogurt can promote weight loss, especially due to the calcium in the yogurt.
Brain Bee Results
Submitted by tsurtees on Tue, 01/31/2012 - 10:32am. NeuroscienceNo, sonic hedgehog is not just a video game character; it's also a signalling molecule involved in the development of the central nervous system. And "malleus" refers not just to it's Latin meaning, "hammer," but also to a bone in the inner ear. All of this and more was uncovered at the Second Annual St. Louis Area Brain Bee.
The event included a day of friendly competition, demonstrations with electric fish, hands-on human brain activities, hearing action potentials in cricket legs, and a Q&A session with a panel of neuroscientists. Competitors in the bee took a written exam with questions coming from the Society for Neuroscience's Brain Facts Book. The top ten performers on the exam then qualified for the oral rounds.
Nathan Nguyen, a student from John Borroughs School took first place in the bee. Placing second and third respectively were Smitha Milli and Poornaashri Malarvannar. Two YES teens made it into the oral rounds, Richard Shoyoola and Antoine Watkins. Antoine was one of the final seven students in the competition. We're very proud of all the YES teens and outside students who participated and grateful to the neuroscience volunteers who helped make the day such a phenomenal success!
