tags: kinematics, kinetics, running,The Barefoot Professor, exercise physiology, barefoot running, NPG, peer-reviewed research, NATURE, 10.1038/nature08723, streaming video Harvard professor Daniel Lieberman ditched his trainers and started running barefoot. His research shows that barefoot runners, who tend to land on their fore-foot, generate less impact shock than runners in sports shoes who land heel first. This…

Dwarf Galaxy Dance

tags: astronomy, cosmology, black obelisks, Dwarf Galaxy Dance, formation of dwarf galaxies, cold dark matter model, NPG, peer-reviewed research, NATURE, 10.1038/nature08640, streaming video This beautiful animation shows how exploding stars are a key force in shaping dwarf galaxies. Fabio Governato and colleagues present computer simulations that appear to have solved a longstanding problem in cosmology…

Bacteria Make Mexican Waves

tags: synthetic biology, molecular biology, genetics,Bacteria make Mexican Waves, A synchronized quorum of genetic clocks, bacteria, fluorescence,biological clock, NPG, peer-reviewed research, NATURE, 10.1038/nature08753, streaming video By synchronizing our clocks, we can coordinate our activities with people around the world. Now, scientists have genetically engineered bacteria to synchronize their molecular timekeepers, creating the stunning fluorescent waves…

tags: peer-reviewed paper, psychology, gift wrapping, wrapping paper, behavior, holidays, holidaze Besides bright lights, my favorite thing about the holidays is wrapping gifts. I love covering a boxed gift with colored papers (or even with plain brown paper bags), I get tremendous satisfaction from folding the paper so it makes precise corners and then I…
