The search for dark matter: Axions have ever fewer places to hide

Wed, 14 Feb 18 00:03:40 -0800

If they existed, axions -- one of the candidates for particles of the mysterious dark matter -- could interact with the matter forming our world, but they would have to do this to a much, much weaker extent than it has seemed up to now. New, rigorous constraints on the properties of axions have been imposed by an international team of scientists responsible for the nEDM experiment.

These bacteria produce gold by digesting toxic metals

Wed, 31 Jan 18 00:08:00 -0800

High concentrations of heavy metals, like copper and gold, are toxic for most living creatures. This is not the case for the bacterium C. metallidurans, which has found a way to extract valuable trace elements from a compound of heavy metals without poisoning itself. One interesting side-effect: the formation of tiny gold nuggets. A team of researchers led by Martin Luther University Halle-Wittenberg (MLU) has discovered the molecular processes that take place inside the bacteria.

NASA team studies middle-aged sun by tracking motion of Mercury

Thu, 18 Jan 18 00:06:00 -0800

Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun's gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury's orbit.



Heavy-petroleum fuels raising vanadium emissions

Fri, 15 Dec 17 00:16:10 -0800

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.

Researchers from RUDN University and P. G. Demidov Yaroslavl State University have demonstrated the association between changes in the concentration of trace elements in blood (especially zinc) with prediabetes -- a condition preceding the disease. The obtained data suggest that zinc metabolism disorders play an important role in the development of the disease. The results of the study were published in Journal of Trace Elements in Medicine and Biology.



Dental filling failure linked to smoking, drinking and genetics

Mon, 06 Nov 17 00:16:30 -0800

Researchers find that people who drink alcohol or men who smoke are more likely to suffer a failed dental filling. The research team also found a genetic difference in some patients associated with increased filling failure rates. In contrast, no major difference in filling failure rates was found between traditional amalgam and newer composite resin fillings. The results suggest that personalized dental treatments could lead to improved outcomes.



Artificial neural networks could power up curation of natural history collections
