| A Snake in the Wetlands
Posted: 05 Jun 2020 12:01 AM PDT  Carved from the swamps, we dredged your home to make way for our own; squaring the deal with metals that were no longer precious. Their caustic arrival painting our castoffs in violent hues of indelible ink; a technicolour of toxicity that leached across the landscape. Slithering through the sediment like a scaled canary, your yellowed […] |
| Wabtec introduces air-contaminant-filtering device for railcar interiors
Posted: 04 Jun 2020 02:01 PM PDT The below Jun. 1, 2020 press release is from Wabtec Corp. Wabtec Corporation launched an air-filtration innovation, called BlueFilter®, to provide a clean, healthy environment for passengers on metro and trains. The TÜV-tested filter continuously provides fresh and clean air onboard metro and railcars by removing more than 90 percent of contaminants per air cycle. […]

| Hydrologists show environmental damage from fog reduction is observable from outer space
Posted: 04 Jun 2020 01:45 PM PDT  A new study led by ecohydrologists at IUPUI has shown for the first time that it’s possible to use satellite data to measure the threat of climate change to ecological systems that depend on water from fog. The paper, published in the journal Geophysical Research Letters, presents the first clear evidence that the relationship between fog […] |
| New Visa Restrictions will Make the U.S. Economic Downturn Worse
Posted: 04 Jun 2020 01:41 PM PDT  The Trump administration is expected to set limits on a popular program that allows international students to work in the U.S. after graduation while remaining on their student visas. The restrictions on the Optional Practical Training (OPT) program are designed to help American graduates seeking jobs during the pandemic-fueled economic downturn; however, the move is […] |
| Self-assembling, biomimetic composites possess unusual electrical properties
Posted: 04 Jun 2020 01:40 PM PDT  Sometimes, breaking rules is not a bad thing. Especially when the rules are apparent laws of nature that apply in bulk material, but other forces appear in the nanoscale. “Nature knows how to go from the small, atomic scale to larger scales,” said Melik Demirel, professor of engineering science and mechanics and holder of the […] |
| Showtime for Photosynthesis
Posted: 04 Jun 2020 01:38 PM PDT  Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism behind the water splitting reaction of photosynthesis, a finding that could help inform the design of renewable energy technology. “Life depends on the oxygen that plants and algae split from water; how […] |
| Q&A: Coronavirus has shown the need for a global health system – but revealed its weaknesses too
Posted: 04 Jun 2020 01:31 PM PDT  We are seeing a failure of global health governance in response to Covid-19 because there are too many agencies with different interests, according Professor Colin McInnes, pro-vice chancellor at Aberystwyth University in Wales, UK, who says global institutions such as the World Health Organization and World Bank should stand together in crises. He ran a […] |
| Studies of Brain Activity Aren’t as Useful as Scientists Thought
Posted: 04 Jun 2020 11:25 AM PDT  Hundreds of published studies over the last decade have claimed it’s possible to predict an individual’s patterns of thoughts and feelings by scanning their brain in an MRI machine as they perform some mental tasks. But a new analysis by some of the researchers who have done the most work in this area finds that […] |
| Study ties stroke-related brain blood vessel abnormality to gut bacteria
Posted: 04 Jun 2020 11:24 AM PDT  In a nationwide study, NIH funded researchers found that the presence of abnormal bundles of brittle blood vessels in the brain or spinal cord, called cavernous angiomas (CA), are linked to the composition of a person’s gut bacteria. Also known as cerebral cavernous malformations, these lesions which contain slow moving or stagnant blood, can often cause […] |
| Some types of prostate cancer may not be as aggressive as originally thought
Posted: 04 Jun 2020 11:21 AM PDT  Researchers at the UCLA Jonsson Comprehensive Cancer Center analyzed gene-expression patterns in the most aggressive prostate cancer grade group — known as Gleason grade group 5 — and found that this grade of cancer can actually be subdivided into four subtypes with distinct differences. The findings may affect how people are treated for the disease. […] |
