Dementia risk increased in 50-year-olds with blood pressure below hypertension threshold Posted: 12 Jun 2018 05:18 PM PDT New findings from the long-running Whitehall II study of over 10,000 civil servants has found 50-year-olds who had blood pressure that was higher than normal but still below the threshold commonly used when deciding to treat the condition, were at increased risk of developing dementia in later life. This increased risk was seen even when the study participants did not have other heart or blood vessel-related problems, according to the research. |

Psychedelic drugs promote neural plasticity in rats and flies Posted: 12 Jun 2018 03:52 PM PDT Psychedelic drugs may have mind-altering powers in the physical sense, too. A new study has found psychedelics, specifically DOI, DMT, and LSD, can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. The work supports the theory that psychedelics could help to fight depression, anxiety, addiction, and post-traumatic stress disorder. |

Core electron topologies in chemical bonding Posted: 12 Jun 2018 03:51 PM PDT Researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides for the first time reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. Other elements with a similar propensity as carbon to reshape their core electron nodal structures upon chemical bonding are proposed. |

People who deeply grasp pain or happiness of others, process music differently in brain Posted: 12 Jun 2018 03:51 PM PDT People who deeply grasp the pain or happiness of others also process music differently, say researchers. The study in Frontiers in Behavioral Neuroscience compared MRI scans of low- and high-empathy people. Higher empathy people process music like a pleasurable proxy for a human encounter -- in brain regions for reward and social awareness. The findings may have implications for the function of music now and in our evolutionary past. |
Beyond the 'Reading Wars': How the science of reading can improve literacy Posted: 12 Jun 2018 03:51 PM PDT A new scientific report from psychological researchers aims to resolve the so-called 'reading wars,' emphasizing the importance of teaching phonics in establishing fundamental reading skills in early childhood. The report shows how early phonics skills are advanced with a rich reading curriculum throughout the school years. |

New GAIA data reveals mergers in Milky Way Posted: 12 Jun 2018 03:51 PM PDT University of Groningen astronomers have discovered relics of merger events in the Milky Way halo. Five small groups of stars appear to represent mergers with smaller galaxies, while a big 'blob' comprising hundreds of stars appears to be the remnant of a large merger event. These results were published in The Astrophysical Journal Letters on 12 June. |
Bacterial enzymes: The biological role of europium Posted: 12 Jun 2018 03:51 PM PDT Rare earth elements (REEs) are an indispensable component of the digital technologies that are now an integral part of our everyday life. Yet their biological role has been discovered only recently. A few years ago it became apparent that these metals are essential elements for methano- and methylotrophic bacteria. One representative is the bacterium Methylacidiphilum fumariolicum SolV, which was found in a volcanic mudpot near Naples, Italy, and is known to be strictly dependent on REEs such as lanthanum and cerium for its growth. |

Discovery shines light on the mystery of cell death in MS Posted: 12 Jun 2018 03:50 PM PDT Researchers have discovered a unique process of brain cell death that affects the cells that are most vulnerable in multiple sclerosis (MS). After identifying the process called pyroptosis, or fiery death, the researchers were able to block the enzyme in the brain that is responsible for it, using a drug that could potentially treat MS. |

The true power of the solar wind Posted: 12 Jun 2018 07:57 AM PDT The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought. |
The loss of a parent is the most common cause of brood failure in blue tits Posted: 12 Jun 2018 07:57 AM PDT Complete brood failure in blue tits is almost always associated with the sudden and permanent disappearance of one of the parents. Scientists show in their study that the remaining parent substantially increased its effort to raise at least some of the chicks, which turned out to be successful in two thirds of the nests. |

Protective mechanism against atherosclerosis discovered Posted: 12 Jun 2018 07:57 AM PDT Immune cells promoting inflammation play a crucial role in the development of atherosclerosis. Scientists showed that a survival factor for those cells has also anti-inflammatory functions and a protective role in atherosclerosis. The study, published in Circulation, provides valuable new insight for atherosclerosis research and suggests a hitherto unknown, inherited risk factor for atherosclerosis. |

Graphene carpets: So neurons communicate better Posted: 12 Jun 2018 07:57 AM PDT Scientists have experimentally observed the phenomenon of ion 'trapping' by graphene carpets and its effect on the communication between neurons. The researchers have observed an increase in the activity of nerve cells grown on a single layer of graphene. Combining theoretical and experimental approaches they have shown that the phenomenon is due to the ability of the material to 'trap' several ions present in the surrounding environment on its surface, modulating its composition. |

Basketball teams playing for survival in critical NBA playoffs are more likely to lose Posted: 12 Jun 2018 05:00 AM PDT A new study finds that basketball teams playing for survival in critical NBA playoff games are more likely to lose. This study is the first to illustrate 'choking' in a real-world team sports environment. The results suggest that 'choking' is a common phenomenon in high-stakes situations and may be applicable to a variety of high-pressure performance situations, including those found in the workplace. |

Finally, hope for a syphilis vaccine Posted: 12 Jun 2018 05:00 AM PDT Despite efforts to eradicate it, syphilis is on the rise. It is the second leading cause of stillbirth and miscarriage worldwide, and if left untreated it can cause strokes, dementia, and other neurological disease. Until now, most health agencies focused on treating infected people and their sex partners -- but new discoveries may make a vaccine possible. |
Multiple lasers could be replaced by a single microcomb Posted: 12 Jun 2018 05:00 AM PDT Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb. |
Long periods of viral suppression shown to reduce cancer risk in aging HIV population Posted: 11 Jun 2018 02:24 PM PDT Early, sustained antiretroviral therapy (ART), which results in long-term viral suppression, helps to prevent AIDS-defining cancers and also non-AIDS-defining cancers, to a lesser degree. However, patients with long-term viral suppression still had excess cancer risk compared to uninfected patients. |
