It is especially promising for analyzing fine particulate matter measuring less than 2.5 microns (PM2.5), which can reach deep into the lungs and cause health problems. http://creativecommons.org/licenses/by-nc-sa/3.0/ Finding common ground for scientists and policymakers on soil carbon and climate change https://phys.org/news/2019-11-common-ground-scientists-policymakers-soil.html https://phys.org/news/2019-11-common-ground-scientists-policymakers-soil.html Mon, 11 Nov 2019 20:58:33 UTC Phys.org - latest science and technology news stories There is growing interest in the potential for soil carbon to mitigate climate change, brought into the public sphere at the 2015 United Nations Climate Change Conference (COP21) in Paris. France. There, the French government launched an international initiative, "4per1000," aimed at reducing greenhouse gas emissions by building soil carbon. http://creativecommons.org/licenses/by-nc-sa/3.0/ 'Ghost' footprints from Pleistocene era revealed by radar tech https://phys.org/news/2019-11-ghost-footprints-pleistocene-era-revealed.html https://phys.org/news/2019-11-ghost-footprints-pleistocene-era-revealed.html Mon, 11 Nov 2019 20:56:26 UTC Phys.org - latest science and technology news stories Invisible footprints hiding since the end of the last ice age—and what lies beneath them—have been discovered by Cornell University researchers using a special type of radar in a novel way. http://creativecommons.org/licenses/by-nc-sa/3.0/ Gold mining critically impairs water quality in rivers across Peruvian biodiversity hotspot https://phys.org/news/2019-11-gold-critically-impairs-quality-rivers.html https://phys.org/news/2019-11-gold-critically-impairs-quality-rivers.html Mon, 11 Nov 2019 20:00:14 UTC Phys.org - latest science and technology news stories A Dartmouth study finds that artisanal-scale gold mining is altering water clarity and dynamics in the Madre de Dios River watershed in Peru, a tropical biodiversity hotspot. Higher levels of suspended sediment were found in rivers near the mining sites, with increasing impacts as mining has become more widespread in the past two decades. The elevated sediment levels contain mercury and other contaminants, which can pose health risks to humans and have a detrimental impact on fish populations and other aquatic life. The findings are published in the Proceedings of the National Academy of Sciences. http://creativecommons.org/licenses/by-nc-sa/3.0/ Study reveals how two strains of one bacterium combine to cause flesh-eating infection https://phys.org/news/2019-11-reveals-strains-bacterium-combine-flesh-eating.html https://phys.org/news/2019-11-reveals-strains-bacterium-combine-flesh-eating.html Mon, 11 Nov 2019 20:00:13 UTC Phys.org - latest science and technology news stories In recent years, scientists have found that serious infections that progress rapidly and resist treatment are often caused by multiple microbes interacting with one another. Very little is known about these so-called polymicrobial infections, but traditional diagnostic methods often misidentify them as monomicrobial, or single-microbe, infections. http://creativecommons.org/licenses/by-nc-sa/3.0/ New research explains how HIV avoids getting ZAPped https://phys.org/news/2019-11-hiv-zapped.html https://phys.org/news/2019-11-hiv-zapped.html Mon, 11 Nov 2019 20:00:12 UTC Phys.org - latest science and technology news stories Humans have evolved dynamic defense mechanisms against the viruses that seek to infect our bodies—proteins that specialize in identifying, capturing and destroying the genetic material that viruses try to sneak into our cells. http://creativecommons.org/licenses/by-nc-sa/3.0/
