Contaminants in food: Health risks of natural origin are frequently underestimated

Fri, 15 Sep 17 00:10:00 -0700

Just under 60 percent of the German population view undesirable substances in food as a high or very high health risk. The most well-known of these substances, which are scientifically denoted as contaminants, are mercury compounds and dioxins. In contrast, only around 13 percent of respondents have heard of the natural contaminants pyrrolizidine alkaloids (PAs) in honey or tea - and only roughly one in three of those who have heard of PAs believe these substances pose a significant health risk.

Keeping NASA's James Webb Space Telescope in the dark

Tue, 12 Sep 17 00:03:00 -0700

This bunny-suited technician is performing the important task of ensuring no unwanted infrared light interferes with the optical testing of NASA's James Webb Space Telescope inside of Chamber A at NASA's Johnson Space Center in Houston.

Are we being watched? Tens of other worlds could spot the Earth

Fri, 08 Sep 17 00:13:10 -0700

A group of scientists from Queen's University Belfast and the Max Planck Institute for Solar System Research in Germany have turned exoplanet-hunting on its head, in a study that instead looks at how an alien observer might be able to detect Earth using our own methods. They find that at least nine exoplanets are ideally placed to observe transits of Earth, in a new work published in the journal Monthly Notices of the Royal Astronomical Society.

SwRI-led study captures science data from Great American Eclipse

Thu, 24 Aug 17 00:01:10 -0700

Two NASA WB-57F research aircraft successfully tracked the August 21 solar eclipse as part of a NASA project led by Southwest Research Institute (SwRI) to study the solar corona and Mercury's surface.

Studies reveal worrisome trend for health of wild dolphins

Wed, 23 Aug 17 00:12:10 -0700

Twelve years of data on the health of two Atlantic bottlenose dolphin populations paints a grim reality concerning the wellbeing of the Atlantic Ocean. The research compiles findings from Georgia Aquarium, Harbor Branch Oceanographic Institution at Florida Atlantic University and contributing partners as part of the Health and Environmental Risk Assessment Project (HERA) from 2003-2015. It informs researchers about the health of dolphins and prompted additional studies on how the environment may impact human health.

Mercury is altering gene expression

Tue, 15 Aug 17 00:13:50 -0700

Mercury causes severe neurological disorders in people who have consumed highly contaminated fish. Whereas we know about the element's extreme toxicity, what happens further down the food chain, all the way down to those microalgae that are the first level and the gateway for mercury? By employing molecular biology tools, a team of researchers from UNIGE measured the way mercury affects the gene expression of algae, even when its concentration in water is very low.

Mainz-based researchers stabilized gold in very rare oxidation state +II

Tue, 08 Aug 17 00:00:50 -0700

A team of chemists led by Professor Katja Heinze at the Institute of Inorganic Chemistry and Analytical Chemistry of JGU has been able to isolate and analyze gold in the very rare oxidation state +II. This provides the missing links in the homologous series of the coinage metal ions copper(+II), silver(+II), gold(+II), and in the 'relativistic' triad of platinum(+II), gold(+II), and mercury(+II).

Heavy metals in water meet their match

Thu, 27 Jul 17 00:02:30 -0700

A high school student's project that was developed at Rice University and won national and international awards removes more than 99 percent of heavy metal toxins from water. A new paper demonstrates its potential for water remediation in developing nations around the world.

Solar eclipse science along the path of totality

Thu, 27 Jul 17 00:11:30 -0700

In a briefing today on solar eclipse science, leading US. scientists highlighted research projects that will take place across the country during the upcoming Aug. 21 solar eclipse. The research will advance our knowledge of the sun's complex and mysterious magnetic field and its effects on Earth's atmosphere and land.

Ingestible drug-delivery materials may help patients comply with treatment regimens

Tue, 25 Jul 17 00:15:10 -0700

To ensure patients receive full medicinal treatments, engineers at MIT and Brigham and Women's Hospital have developed a new set of hydrogel-based drug delivery materials, which can live in the stomach up to nine days, slowly releasing medication.

Chasing the Total Solar Eclipse from NASA's WB-57F jets

Tue, 25 Jul 17 00:06:30 -0700

A team of NASA-funded scientists will take to the skies during the Aug. 21 eclipse, using two of NASA's WB-57 jet planes to chase the shadow of the moon for unparalleled observations of the sun and Mercury.

Molting feathers may help birds deal with environmental contaminants

Thu, 20 Jul 17 00:06:30 -0700

Mercury is a ubiquitous environmental contaminant that affects the health of birds and other wild animals.

Scientists reveal new connections between small particles and the vast universe

Wed, 19 Jul 17 00:02:40 -0700

Are density distributions of the vast universe and the nature of smallest particles related? In a recent research, scientists from HKUST and Harvard University revealed the connection between those two aspects, and argued that our universe could be used as a particle physics 'collider' to study the high energy particle physics. Their findings mark the first step of cosmological collider phenomenology and pave the way for future discovery of new physics unknown yet to mankind.

Study finds toxic mercury is accumulating in the Arctic tundra

Wed, 12 Jul 17 00:11:00 -0700

Vast amounts of toxic mercury are accumulating in the Arctic tundra, threatening the health and well-being of people, wildlife and waterways, according to a UMass Lowell scientist investigating the source of the pollution.

Nature-inspired material uses liquid reinforcement

Mon, 10 Jul 17 00:09:00 -0700

Materials scientists at Rice University are looking to nature -- at the discs in human spines and the skin in ocean-diving fish, for example -- for clues about how to use liquid to increase the stiffness of flexible composites.

Microbe study highlights Greenland ice sheet toxicity

Mon, 10 Jul 17 00:10:30 -0700

The Greenland ice sheet is often seen as a pristine environment, but new research has revealed that may not be the case. A Danish-led study, published today in the journal Environmental Research Letters, examined how microbes from the ice sheet have the potential to resist and degrade globally-emitted contaminants such as mercury, lead, PAH and PCB.

New sensors could enable more affordable detection of pollution and diseases

Wed, 21 Jun 17 00:05:50 -0700

When it comes to testing for cancer, environmental pollution and food contaminants, traditional sensors can help. The challenges are that they often are bulky, expensive, non-intuitive and complicated. Now, one team reports in ACS Sensors that portable pressure-based detectors coupled with smartphone software could provide a simpler, more affordable alternative while still maintaining sensitivity.
