CERN Physicists Discover Four-Charm-Quark Particle
Physicists from CERN’s LHCb Collaboration have discovered a new tetraquark particle, named X(6900), composed of two charm quarks and two charm antiquarks. Quarks are point-like elementary particles that typically come in packages of two (mesons) or three (baryons), the most familiar of which are the proton and neutron — each is made of three quarks.

Stretching your legs may help prevent diseases such as heart diseases and diabetes
New research shows that 12 weeks of easy-to-administer passive stretching helps improve blood flow by making it easier for your arteries to dilate and decreasing their stiffness.
Implicit bias against women: Men more likely than women to be seen as brilliant
Men are more likely than are women to be seen as ''brilliant,'' finds a new study measuring global perceptions linked to gender. The work concludes that these stereotyped views are an instance of implicit bias, revealing automatic associations that people cannot, or at least do not, report holding when asked directly.
Understanding the circadian clocks of individual cells
Scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means. These findings help explain how organisms' circadian clocks maintain flexibility and could offer insights into aging and cancer.
New candidate for raw material synthesis through gene transfer
Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms as they often occur in waters. A group of researchers has discovered that the multicellular species Phormidium lacuna can be genetically modified by natural transformation and could thus produce substances such as ethanol or hydrogen.
Early marriage may lead to unsafe drinking behavior by those with higher genetic risk
Getting married early in life may increase the risk of problematic drinking behavior among people who are genetically predisposed to drink more.
Moss protein corrects genetic defects of other plants
Almost all land plants employ an army of molecular editors who correct errors in their genetic information. Researchers have now transferred one of these proofreaders from the moss Physcomitrium patens (previously known as Physcomitrella patens) into a flowering plant. Surprisingly, it performs its work there as reliably as in the moss itself.
Radio Telescopes Reveal Lukewarm Atmosphere of Nearby Red Supergiant Star Antares
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and NSF’s Karl G. Jansky Very Large Array (VLA) have created the most detailed map yet of the atmosphere of Antares, one of the largest and brightest stars visible to naked eye in the night sky. Antares is located approximately 554 light-years away in the constellation of [...]
Physicists Observe Branched Flow of Light
Physicists from the Technion-Israel Institute of Technology and the University of Central Florida have experimentally observed optical branched flow in liquid soap films. Waves propagating through a weak disordered potential with correlation length larger than the wavelength produce surprisingly long narrow filaments, or branches. Instead of producing completely random speckle patterns, the slowly varying disordered [...]
Smart structures: Structural cells of the body control immune function
Researchers analyzed the epigenetic and transcriptional regulation in structural cells. They found widespread activity of immune genes, suggesting that structural cells are deeply involved in the body's response to pathogens. Moreover, the study uncovered an epigenetic potential that pre-programs structural cells to engage in the immune response against pathogens. These findings highlight an underappreciated part of the immune system and open up an exciting area for research and future therapies.
Infant sleep problems can signal mental disorders in adolescents
Specific sleep problems among babies and very young children can be linked to mental disorders in adolescents, a new study has found.
Materials scientists drill down to vulnerabilities involved in human tooth decay
Researchers have cracked one of the secrets of tooth decay. The materials scientists are the first to identify a small number of impurity atoms in human enamel that may contribute to the material's strength but also make it more soluble. They also are the first to determine the spatial distribution of the impurities with atomic-scale resolution. The discovery could lead to a better understanding of human tooth decay as well as genetic conditions that affect enamel formation.
Energy-saving servers: Data storage 2.0
A research team has developed a technique that will potentially halve the energy required to write data to servers and make it easier to construct complex server architectures.
Long-term culture of human pancreatic slices reveals regeneration of beta cells
Scientists have developed a method allowing for the long-term culture of 'pancreatic slices' to study the regeneration of the human pancreas in real time.
New system combines smartphone videos to create 4D visualizations
Researchers have demonstrated that they can combine iPhone videos shot 'in the wild' by separate cameras to create 4D visualizations that allow viewers to watch action from various angles, or even erase people or objects that temporarily block sight lines.
Mystery of subterranean stoneflies unlocked
Researchers may have unlocked a mystery surrounding unique aquatic insects in the Flathead watershed.
Study confirms ultra music festival likely stressful to fish
A new study found that the Ultra Music Festival was likely stressful to toadfish.
Treatments tested for invasive pest on allium crops
Researchers field-tested 14 active ingredients in insecticides, applied in a variety of methods, to understand the best treatment options against the Allium leafminer, a growing threat to onions, garlic and leeks.
Giant leap in diagnosing liver disease
Scientists have created a novel microbiome-based diagnostic tool that, with the accuracy of the best physicians, quickly and inexpensively identifies liver fibrosis and cirrhosis over 90 percent of the time in human patients. The non-invasive method relies on an algorithm to analyze patient stool samples -- which contains traces of what lives in the gut -- and could lead to improved patient care and treatment outcomes for liver disease.
Level of media coverage for scientific research linked to number of citations
An analysis of over 800 academic research papers on physical health and exercise suggests that the level of popular media coverage for a given paper is strongly linked to the attention it receives within the scientific community.
