Soot may have killed off the dinosaurs and ammonites Posted: 15 Jul 2016 08:35 AM PDT A new hypothesis on the extinction of dinosaurs and ammonites at the end of the Cretaceous Period has been proposed by a research team.

Garlic aroma found in breast milk Posted: 15 Jul 2016 08:27 AM PDT Food chemists have found that garlic aroma is evident in the breast milk of women who have consumed garlic. This is caused by allyl methyl sulfide -- a metabolite which is first formed in a strong concentration during breastfeeding. Whether the aroma has an impact on which food preferences children develop and whether they like garlic in later life needs to be clarified by further research.

Scientists move one step closer to creating an invisibility cloak Posted: 15 Jul 2016 08:27 AM PDT Scientists have made an object disappear by using a material with nano-size particles that can enhance specific properties on the object's surface.

Measuring oceans of activity in one drop of water Posted: 14 Jul 2016 10:52 AM PDT You'll never look at a drop of water the same way. By measuring a water droplet with a resolution comparable with the scale of a single atom, scientists have determined that the droplet interface behaves like a miniature stormy sea even when it appears to be at rest.

Bacteria avoid age defects through collective behavior Posted: 14 Jul 2016 10:51 AM PDT Biophysics: As they age, more and more defects arise in most organisms. Researchers have discovered that microorganisms like bacteria can keep a colony young by practicing a common strategy for propagation. The same may be true for, for example, stem cells in humans.

The Ouzo Effect under the magnifying glass Posted: 14 Jul 2016 06:17 AM PDT Pour some water into your glass of ouzo or pastis, and the beverage will change from transparent to milky: this is the well-known 'Ouzo effect'. But what will happen if you simply place a drop of ouzo on a surface and wait? Scientists have studied the phenomena taking place, and distinguish four 'life phases' of the drop, within no more than a quarter of an hour.

Western-style diet linked to state-dependent memory inhibition Posted: 12 Jul 2016 06:24 AM PDT Obesity may ultimately be a disease of the brain, involving a progressive deterioration of various cognitive processes that influence eating. Researchers have now shown that memory inhibition -- the useful ability to 'block out' memories that are no longer useful, which depends on a brain area called the hippocampus -- is linked to dietary excess.
