Geothermal manifestations at Earth's surface can be mapped and characterized by a variety of well-established exploration methods. However, mapping hydrothermal vents in aquatic environments is more challenging as conventional methods can no longer be applied. In fact, chemical composition of lake water may indicate inflow of fluids from a volcanic system, but it does not provide spatial information on the location of hydrothermal vents, their abundance and current state of activity.
When two neutron stars collide, the matter at their core enters extreme states. An international research team has now studied the properties of matter compressed in such collisions. The HADES long-term experiment, involving more than 110 scientists, has been investigating forms of cosmic matter since 1994. With the investigation of electromagnetic radiation arising when stars collide, the team has now focused attention on the hot, dense interaction zone between two merging neutron stars.

Washington, D.C. (August 22, 2019) - A new report published in the July issue of the Journal of the American College of Nutrition by pediatrician Dr. Robert D. Murray supports existing scientific data maintaining juice as part of a healthy diet. The report reinforces that claims that 100% juice may be associated with childhood weight gain or negative health outcomes have not been supported by recent scientific research including a number of systematic reviews and meta-analyses.
A team of scientists from School of Engineering at Far Eastern Federal University (FEFU), Institute of Automation and Control Processes, and Institute of Marine Technology Problems of the Far Eastern Department of the Russian Academy of Sciences developed a software module to automatically diagnose defects in sensors and electric drives in various kinds of robots. The system is able to compensate for the detected defects in real time.
Swansea University scientists have reported a new approach to measuring the conductivity between identical carbon nanotubes which could be used to help improve the efficiency of electrical power cables in the future.
AUGUST 22, 2019, NEW YORK-- A Ludwig Cancer Research study has uncovered a novel vulnerability in tumors that are driven by a common cancer gene known as MYC. Such cancers, it found, are highly dependent on the cell's machinery for making fats and other lipids.
Oak Brook, IL - In September's SLAS Discovery cover article, "Using Physicochemical Measurements to Influence Better Compound Design," authors Robert J. Young, Ph.D., Shenaz B. Bunally, Ph.D., and Chris N. Luscombe, Ph.D., (GlaxoSmithKline) outline commonly used physiochemical properties and how they are assessed and measured throughout the drug discovery process, while also explaining the implications of each property that have led to flawed results. This review also offers suggestions on which contemporary methods can be used to improve subpar testing outcomes.
CINCINNATI--The extract of the leaves of Ginkgo biloba, a popular dietary supplement, may offer some therapeutic benefits in fighting Type 2 diabetes, according to a study co-authored by a researcher at the University of Cincinnati (UC) College of Medicine.
More than 200,000 people are employed as truck drivers in Australia and while their role in transporting goods across our wide brown land is critical, they are among the nation's most unhealthy.
Dr Marguerite Sendall from QUT's School of Public Health and Social Work at the Institute of Health and Biomedical Innovation, led a survey of 231 truck drivers aged between 20 and 71 and discovered around two thirds of them are classified as obese, compared to one third of the Australian population.
The Earth's subsurface is an extremely active place, where the movements and friction of plates deep underground shape our landscape and govern the intensity of hazards above. While the Earth's movements during earthquakes and volcanic eruptions have been recorded by delicate instruments, analyzed by researchers and constrained by mathematical equations, they don't tell the whole story of the shifting plates beneath our feet.
ROCHESTER, Minn. -- Parents, siblings and children of people with celiac disease are at high risk of also having the disease, according to a Mayo Clinic study. This study calls for screening of all first-degree relatives of patients -- not just those who show symptoms.
The retrospective study, to be published in Mayo Clinic Proceedings in September, found that 44% of screened first-degree relatives had celiac disease. Of those patients, 94% had symptoms that were not classic or had no symptoms at all.
ROCHESTER, Minn. -- Cannabidiol (CBD) oils and products have become increasingly popular with consumers as ways to find relief from aches and pains, anxiety, sleep disturbances and other chronic issues. But are these products safe, and are they helpful?
AUGUSTA, Ga. (Aug. 22, 2019) - An enzyme induced by stress to help reduce production of damaging free radicals is also used by liver cancer to regulate two major cell proliferation pathways that enable the cancer to thrive, scientists report.
They've also found that when they block the enzyme Nqo1, it dramatically reduces the proliferation of liver cancer cells, a hallmark of cancer's ability to survive and thrive, they report in the journal HEPATOLOGY.
In order to orient themselves and survive in their environment, animals must develop a concept of their own body size. Researchers at Johannes Gutenberg University Mainz (JGU) have shown that the fruit fly Drosophila melanogaster develops a very stable long-term memory for its own body size and the reach of its extremities after it has hatched from the pupal case. The fruit fly acquires this memory through visual feedback obtained when walking, but in the first two hours after training the memory is still susceptible to the effects of stress and not yet firmly anchored.
Matter behaves differently when it's tiny. At the nanoscale, electric current cuts through mountains of particles, spinning them into vortexes that can be used intentionally in quantum computing. The particles arrange themselves into a topological map, but the lines blur as electrons merge into indistinguishable quasiparticles with shifting properties. The trick is learning how to control such changeable materials.
