Fast Learning Bumblebees Reap Greater Nectar Rewards:
The speed with which bees learn affects their ability to collect food from flowers, according to a new study from Queen Mary, University of London. As nectar levels in flowers change from minute-to-minute, faster learning bees are more likely to keep track of which blooms are most rewarding, and thrive as a result.
Living On 'The Red Edge': Rare Form Of Chlorophyll Discovered In Newly Sequenced Bacterium:
Researchers at Washington University in St. Louis and Arizona State University have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs "red edge," near infrared, long wave length light, invisible to the naked eye.
The Way A Protein Is Folded Affects The Molecular Dance Of Water:
Scientists from Bochum, Illinois, and Nevada were able to prove with terahertz (THz) spectroscopy that proteins do modify water molecules in their environment to a long range extent: The water molecules, which generally move around like disco dancers in their collective network motions behave more like in a neat minuet under protein influence.
Quality Schooling Has Little Impact On Teenage Sexual Activity; Socioeconomic Status Does:
A report shows that socio-economic situation and the local high school catchment area have a more powerful influence on reported sexual experience among 15 and 16 year olds than classroom discipline or the quality of relationships within schools.
How Did Huge Dinosaurs Find Enough Food? Did Bacteria Aid Their Digestion?:
Scientists from the University of Bonn are researching which plants giant dinosaurs could have lived off more than 100 million years ago. They want to find out how the dinosaurs were able to become as large as they did. In fact such gigantic animals should not have existed according to general rules of ecology.
