Healthy Bodies Help Fight Disease? Clues To How Diet Affects The Immun Scientists are proposing that dietary fats can affect how well our immune system works and have discoveredthat one of the earliest steps in immune system activation relies on a molecule that binds fats. Common Blood Test Can Help Distinguish Between Mononucleosis And Tonsi Measuring a patient's ratio of white blood cell types may help physicians accurately distinguish between the similar conditions infectious mononucleosis and bacterial tonsillitis, potentially guiding treatment decisions, according to an article in the January issue of Archives of Otolaryngology--Head &Neck Surgery, one of the JAMA/Archives journals. Carnegie Mellon Scientists Create PNA Molecule With Potential To Build For the first time, a team of investigators at Carnegie Mellon University has shown that the binding of metal ions can mediate the formation of peptide nucleic acid (PNA) duplexes from single strands of PNA that are only partly complementary. This result opens new opportunities to create functional, three-dimensional nanosize structures such as molecular-scale electronic circuits, which could reduce by thousands of times the size of today's common electronic devices. How Well Do Dogs See At Night? Dogs see a lot better than humans do at night. Dogs have many adaptations for low-light vision. A larger pupil lets in more light. The center of the retina has more of the light-sensitive cells (rods), which work better in dim light than the color-detecting cones. Mayo Clinic Discovers A Key To 'Low Metabolism' -- And Major Factor In Wiggle, walk, tap your toes, shop, dance, clean your basement, play the guitar to boost your NEAT -- or if you're a scientist, your "non-exercise activity thermogenesis."Mayo Clinic researchers report in the journal Science that NEAT -- more powerful than formal exercise -- determines who is lean, and who is obese. Wired Test 2007: Burning Question - How Hard Is Switching From PC to M Switching to a Mac is not as easy as just buying one, but Apple has brought the two platforms closer together so it's not the minefield it once was. We point the way to a smooth migration of data, e-mail, apps and games, and show you how to navigate the OS itself, which can seem alien to longtime PC mavens. Simple Biodegradable Liquids Stop Bleeding In Seconds MIT and Hong Kong University researchers have shown that some simple biodegradable liquids can stop bleeding in wounded rodents within seconds, a development that could significantly impact medicine. Recovered King Of Beasts Returns To His Home, Thanks To Unique Operati Samson the lion from the Hai-Kef zoo in Rishon Lezion, Israel, who had undergone a brain operation -- unique in the world -- at the Veterinary Teaching Hospital of the Hebrew University of Jerusalem, has recuperated and has returned to his cage and to his sister, Delilah. Hummingbirds Lose Power At High Altitudes Hummingbirds aren't known for their power-lifting prowess. But researchers nevertheless put nearly 1,000 Peruvian hummers through lifting trials and flight tests over a two-year stretch in order to find out how their flying abilities are affected by the lower oxygen and thin air of higher elevations. Human Behavior Changes The Number Of Strains Of Infectious Diseases Simple models predict that only one strain of an infectious disease can exist at one time, but observation suggests otherwise. In a study in the August issue of The American Naturalist, Ken Eames and Matt Keeling (University of Warwick) use a mathematical model to help explain multiple strains, showing that the way humans interact is all-important. The researchers found that the coexistence of multiple infectious disease strains result from monogamous populations.
