Precision medicine for pediatric cancer Posted: 15 Mar 2019 12:55 PM PDT Research performed over the last several decades has led to an increased understanding of the genetics of cancer. The clinical application of this knowledge for pediatric cancer has lagged behind studies performed for adults. Medical researchers now survey the landscape of this young field and present opportunities for using genomic information to advance a new era of care for children with cancer. |

Seeing through a robot's eyes helps those with profound motor impairments Posted: 15 Mar 2019 12:54 PM PDT An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a 'robot's eye view' of surroundings to help users interact with the world through the machine. |

A repellent odor inhibits the perception of a pleasant odor in vinegar flies Posted: 15 Mar 2019 08:09 AM PDT Scientists have discovered that repellent odors suppress the perception of pleasant smells. This happens because certain brain structures that respond to attractive odors are inhibited by a repellent one. These processes in the brain are also reflected in the behavior of the flies. This helps them to avoid spoiled or infected food sources, which would have fatal consequences for the flies and their offspring. |

Higher egg and cholesterol consumption hikes heart disease and early death risk Posted: 15 Mar 2019 08:08 AM PDT Cancel the cheese omelet. A large, new study of nearly 30,000 people reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of cardiovascular disease and death from any cause. People need to consume lower amounts of cholesterol to have a lower risk of heart disease, the study authors said. |

Enzyme USP15 may have potential role in future treatment of various cancers Posted: 15 Mar 2019 06:58 AM PDT |
With single gene insertion, blind mice regain sight Posted: 15 Mar 2019 06:58 AM PDT People left blind by retinal degeneration have one option: electronic eye implants. Neuroscientists have now developed an alternative: gene therapy that, in tests, restored vision in blind mice. A gene for green opsin delivered via virus gave blind mice enough sight to discern patterns on an iPad at a resolution sufficient for humans to read. Given existing AAV eye therapies already approved, this new therapy could be ready for clinical trials in three years. |
Uncovering uncultivated microbes in the human gut Posted: 15 Mar 2019 06:58 AM PDT A human's health is shaped both by environmental factors and the body's interactions with the microbiome, particularly in the gut. Genome sequences are critical for characterizing individual microbes and understanding their functional roles. However, previous studies have estimated that only 50 percent of species in the gut microbiome have a sequenced genome, in part because many species have not yet been cultivated for study. |
How a mitochondrial enzyme can trigger cell death Posted: 14 Mar 2019 12:16 PM PDT Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state NMR, researchers have discovered that the signal induced by cytochrome c is more controlled than expected. |

Unique diversity of the genetic history of the Iberian Peninsula revealed by dual studies Posted: 14 Mar 2019 12:15 PM PDT Researchers have analyzed ancient DNA from almost 300 individuals from the Iberian Peninsula, spanning more than 12,000 years. The first study looked at hunter-gatherers and early farmers living in Iberia between 13,000 and 6,000 years ago. The second looked at individuals from the region over the last 8000 years. Together, the two papers greatly increase our knowledge about the population history of this unique region. |
More vitamin D may improve memory but too much may slow reaction time Posted: 14 Mar 2019 04:57 AM PDT How much vitamin D can boost memory, learning and decision-making in older adults, and how much is too much? A unique study found that overweight and obese older women who took more than three times the recommended daily dose of vitamin D showed improvements in memory and learning -- but also had slower reaction times. The researchers hypothesize that slower reaction times may increase the risk of falling among older people. |
