| Posted: 02 Apr 2014 06:25 PM PDT A surprising new strategy for managing your weight? Bright morning light. People who had most of their daily exposure to bright light in the morning had a significantly lower body mass index (BMI) than those who had most of their light exposure later in the day, reports a new study. The earlier light exposure occurred, the lower the BMI. The influence of morning light on weight was independent of physical activity, caloric intake, sleep timing, age or season. |
| Dinosaur chase reconstructed 70 years after excavation Posted: 02 Apr 2014 06:25 PM PDT Scientists digitally reconstructed a model of a dinosaur chase using photos of theropod and sauropod footprints excavated 70 years ago. As one of the most famous set of dinosaur tracks in the world, the Paluxy River tracks contain both theropod and sauropod footprints. American paleontologist Roland Bird originally excavated the extensive and well preserved footprints in 1940 in Texas, but post-excavation, paleontologists removed the tracks from their original location, divided them into blocks, and transported them to various locations around the world. |
| Body odor changes following vaccination Posted: 02 Apr 2014 06:19 PM PDT New research reveals that immunization can trigger a distinct change in body odor. This is the first demonstration of a bodily odor change due to immune activation. "This work provides further evidence that it is possible to use odors to 'eavesdrop' on the immune system, suggesting that non-invasive disease detection may be possible even before the onset of observable symptoms," one of the researchers said. |
| The science of champagne fizz: How many bubbles are in your bubbly? Posted: 02 Apr 2014 08:00 AM PDT The importance of fizz, more technically known as effervescence, in sparkling wines and champagnes is not to be underestimated -- it contributes to the complete sensory experience of a glass, or flute, of fine bubbly. A scientist has now closely examined the factors that affect these bubbles, and he has come up with an estimate of just how many are in each glass. |
| Rainy day can ruin online restaurant review Posted: 02 Apr 2014 07:55 AM PDT After looking at 1.1 million online reviews for 840,000 restaurants in more than 32,000 cities across the country, researchers have found that the weather outside can be just as significant a factor for reviews as what happens inside a restaurant. The study shows evaluations written on rainy or snowy days, or very cold or hot days, are more negative than those written on nice days. |
| Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans Posted: 02 Apr 2014 07:00 AM PDT Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans. These shared regions are unevenly distributed across the genome and some regions are particularly enriched with Neanderthal variants. |
| Pigeons share our ability to place everyday things in categories Posted: 02 Apr 2014 06:51 AM PDT Pinecone or pine nut? Friend or foe? Distinguishing between the two requires that we pay special attention to the telltale characteristics of each. And as it turns out, us humans aren't the only ones up to the task. According to researchers, pigeons share our ability to place everyday things in categories. And, like people, they can home in on visual information that is new or important and dismiss what is not. |
