Dietary fiber reduces brain inflammation during aging Posted: 14 Sep 2018 05:48 AM PDT As mammals age, immune cells in the brain known as microglia become chronically inflamed. In this state, they produce chemicals known to impair cognitive and motor function. That's one explanation for why memory fades and other brain functions decline during old age. But, according to a new study, there may be a remedy to delay the inevitable: dietary fiber. |

We have more than enough calories, but what about other nutrients? Posted: 14 Sep 2018 05:48 AM PDT A new study is the first to quantitatively map the flow of energy, protein, fat, essential amino acids and micronutrients from 'field-to-fork' at a global level and identify hotspots where nutrients are lost. The study shows that while we produce far more nutrients than is required for the global population, inefficiencies in the supply chain leave many people nutrient deficient. |

Calorie counts on restaurant menus have customers ordering less Posted: 13 Sep 2018 01:00 PM PDT Researchers conducted a randomized experiment and found that diners at full service restaurants whose menus listed calories ordered meals with 3 percent fewer calories -- about 45 calories less -- than those who had menus without calorie information. Customers ordered fewer calories in their appetizer and entree courses, but their dessert and drink orders remained the same. |

Leptospirosis strains identified in Uruguay cattle Posted: 13 Sep 2018 11:20 AM PDT Leptospirosis infections, caused by Leptospira bacteria, occur in people and animals around the world, but different strains of the bacteria may vary in their ability to cause disease and to jump between species. Now, researchers have for the first time described the characteristics of the Leptospira variants that infect cattle in Uruguay. |

BPA replacements in plastics cause reproductive problems in lab mice Posted: 13 Sep 2018 08:39 AM PDT Twenty years ago, researchers made the accidental discovery that BPA had leached out of plastic cages used to house female mice in the lab, causing an increase in chromosomally abnormal eggs. Now, the same team is back to report that the array of alternative bisphenols now used to replace BPA in BPA-free bottles, cups, cages, and other items appear to come with similar problems for their mice. |
People show confirmation bias even about which way dots are moving Posted: 13 Sep 2018 08:39 AM PDT People have a tendency to interpret new information in a way that supports their pre-existing beliefs, a phenomenon known as confirmation bias. Now, researchers have shown that people will do the same thing even when the decision they've made pertains to a choice that is rather less consequential: which direction a series of dots is moving and whether the average of a series of numbers is greater or less than 50. |

Eyes have a natural version of night vision Posted: 13 Sep 2018 08:39 AM PDT To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed for specific tasks actively adapt to different light conditions, say the scientists who made the discovery. |

Caspase-2 enzyme inhibitor shows promise for ameliorating fatty liver disease Posted: 13 Sep 2018 08:39 AM PDT Researchers have discovered using mice and human clinical specimens that caspase-2, a protein-cleaving enzyme, is a critical driver of non-alcoholic steatohepatitis (NASH), a chronic and aggressive liver condition. By identifying caspase-2's critical role, they believe an inhibitor of this enzyme could provide an effective way to stop the pathogenic progression that leads to NASH -- and possibly even reverse early symptoms. |

BUFFALO charges towards the earliest galaxies Posted: 13 Sep 2018 08:39 AM PDT The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it. |

New means to fight 'un-killable' bacteria in healthcare settings Posted: 13 Sep 2018 08:38 AM PDT Scientists have identified new means of fighting drug-tolerant bacteria, a growing global threat as menacing as drug-resistant microbes. Little is known about the mechanisms leading to tolerance, a strategy that makes bacteria 'indifferent' to antibiotics and almost 'un-killable,' which results in chronic infections extremely difficult to treat and cure. |
