Fruit fly larvae can taste ribonucleosides, the building blocks of gene transcripts, according to a new study publishing on August 7 in the open-access journal PLOS Biology by Hubert Amrein and Dushyant Mishra of Texas A&M Health Science Center and their colleagues. Moreover, the ability to detect ribonucleosides in the environment helps promote the rapid growth needed by developing larvae and dramatically increases their survival.
BUFFALO, N.Y. - Stimulant medications are an effective treatment for Attention-Deficit/Hyperactivity Disorder (ADHD). In the classroom, parents and teachers say that medications like methylphenidate (MPH) can reduce symptoms and improve behavior.
Although stimulants have been in use for decades to treat ADHD in school-aged children, just how they work hasn't been clear. But the results of a new study in the Journal of Child Psychology and Psychiatry is filling in critical gaps about the role of improved cognitive functions.
Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Shiqian Gao, University of Hong Kong, SAR China, gave an oral presentation titled "Silver Nitrate With Sodium Fluoride for Caries Arrest: 18-month Results." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.
During the Late Pleistocene period (between 125,000 to 12,000 years ago) two bear species roamed Europe: omnivorous brown bears (Ursus arctos) and the extinct mostly vegetarian cave bear (Ursus spelaeus).
Until now, very little is known about the dietary evolution of the cave bear and how it became a vegetarian, as the fossils of the direct ancestor, the Deninger's bear (Ursus deningeri), are extremely scarce.
Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Alexandra Clark, Queen Mary University of London, Barts and The London School of Medicine and Dentistry, England gave a poster presentation titled "Exploring the Microbial Dark Matter of the Human Mouth." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.
Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Justin Durham, Newcastle University, England, gave a poster presentation titled "DEEP Study: Modelling Persistent Orofacial Pain Management's Costs and Benefits." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.
Students perform less well in end-of-term exams if they are allowed access to an electronic device, such as a phone or tablet, for non-academic purposes in lectures, a new study in Educational Psychology finds.
Students who don't use such devices themselves but attend lectures where their use is permitted also do worse, suggesting that phone/tablet use damages the group learning environment.
A new drug discovery system allows scientists to specifically target members of an important family of enzymes, called phosphatases, which were previously considered mostly "undruggable".
Scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology, in Cambridge, UK, demonstrated the capabilities of the new system by identifying a molecule that could successfully target a phosphatase to reduce the accumulation of Huntington's disease-associated proteins in the brains of mice.
Growing a batch of carbon nanotubes that are all the same may not be as simple as researchers had hoped, according to Rice University scientists.
Rice materials theorist Boris Yakobson and his team bucked a theory that when growing nanotubes in a furnace, a catalyst with a specific atomic arrangement and symmetry would reliably make carbon nanotubes of like chirality, the angle of its carbon-atom lattice.
WASHINGTON, July 26, 2018 -- Air conditioners pull off the seemingly magical feat of making the air inside a home, car or shopping mall deliciously chilly. The source of that sweet relief is chemistry. In this video, Reactions explains how refrigerants and physical chemistry combine to help you beat the summer heat: https://youtu.be/PT38gaGciP4.
ATLANTA--A thin gap has been discovered on the Hertzsprung-Russell Diagram (HRD), the most fundamental of all maps in stellar astronomy, a finding that provides new information about the interior structures of low mass stars in the Milky Way Galaxy, according to a study led by astronomers at Georgia State University.
Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are new places to observe gravitational waves created when the massive bodies collide, the authors report.
The study winds back time on massive black holes by analyzing their visible precursors--supernovae with collapsing cores. The slow decay of these massive stars creates bright signatures in the electromagnetic spectrum before stellar evolution ends in black holes.
Sexual minorities in the US are less likely to be in work or to have health insurance than their straight peers, reveal the results of a large survey, published in the online journal BMJ Open.
They also have poorer health and quality of life.
These disparities may be even wider as the study sample was predominantly white and from relatively affluent backgrounds, suggest the researchers.
Bottom Line: A panel of 19 microRNAs identified using next-generation sequencing could categorize indeterminate thyroid nodule samples into malignant and benign.
Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
A new gene associated with disease severity in models of rheumatoid arthritis has been identified by researchers at the Icahn School of Medicine at Mount Sinai. The discovery could provide a new pathway for treatment and a way to measure the prognosis of patients diagnosed with the autoimmune condition.
