Researchers at the University of Warwick are examining naturally occurring fungi that kill the varroa mite. They are also exploring a range of ways to deliver the killer fungus throughout the hives from bee fungal foot baths to powder sprays.Source: ScienceDaily: Latest Science News | 29 Jul 2008 | 12:00 am A Hormone That Enhances One’s Memory Of Happy FacesOxytocin was originally studied as the “milk let-down factor,” i.e., a hormone that was necessary for breast-feeding. However, there is increasing evidence that this hormone also plays an important role in social bonding and maternal behaviors. A new study scheduled for publication in the August 1st issue of Biological Psychiatry now shows that one way oxytocin promotes social affiliation in humans is by enhancing the encoding of positive social memories.Source: ScienceDaily: Latest Science News | 29 Jul 2008 | 12:00 am Prostate Cancer Patients Undergoing Hormone Therapy May Experience Cognitive EffectsHormone deprivation therapy, a used for prostate cancer, may have subtle adverse effects on cognition in patients.Source: ScienceDaily: Latest Science News | 29 Jul 2008 | 12:00 am Fish scales may point to armor of the futureWASHINGTON (Reuters) - Scales that protect a quarrelsome fish from the bites of its own fellows as well as from predators may hold the key to the armor of the future, U.S. researchers reported on Sunday.Source: Reuters: Science News | 28 Jul 2008 | 2:53 pm Warp Drive Engine Would Travel Faster Than LightPhysicists outline how to manipulate the fabric of space to accelerate a craft.Source: Discovery News Top Stories : Discovery Channel | 28 Jul 2008 | 2:43 pm 'Dinosaur Eel' Inspires Body Armor of FutureAn ancient African fish could be the model for light, bomb-proof body armor.Source: Discovery News Top Stories : Discovery Channel | 28 Jul 2008 | 2:43 pm Supercontinent Pangea Gets Climate RethinkEarth's famous supercontinent Pangea may have been far colder than thought.Source: Discovery News Top Stories : Discovery Channel | 28 Jul 2008 | 1:40 pm Rock Reunites Antarctica and North America (LiveScience.com)LiveScience.com - A solitary chunk of granite, small enough to heft in one hand, is key evidence that Australia and parts of Antarctica were once attached to North America, a new study suggests. The Earth's continents are thought to have collided to become supercontinents and broken apart again several times in Earth's 4.5 billion year history. The most recent supercontinent was Pangaea, which began to break apart about 200 million years ago; the landmasses that comprised Pangaea eventually wandered into the current configuration of continents. ...Source: Yahoo!
