Photographer and scientist Nathan Myhrvold has developed a camera that captures snowflakes at a microscopic level never seen before. Smithsonian Magazine reports: Myhrvold, who holds a PhD in theoretical mathematics and physics from Princeton University and served as the Chief Technology Officer at Microsoft for 14 years, leaned on his background as a scientist to create the camera. He also tapped…

New study finds polyester fibers throughout the Arctic Ocean
A new study has found that pollution from microplastics is widespread in the Arctic Ocean, and 92% of those particles are minuscule synthetic fibers from our clothes. Source: https://earthsky.org/earth/polyester-fibers-arctic-ocean-microplastic-pollution…
Microplastics Revealed in the Placentas of Unborn Babies
Microplastic particles have been revealed in the placentas of unborn babies for the first time, which the researchers said was “a matter of great concern.” From a report: The health impact of microplastics in the body is as yet unknown. But the scientists said they could carry chemicals that could cause long-term damage or upset the foetus’s developing immune system. The…
SSDs Are Primed To Get Bigger and Faster With Micron’s New NAND Memory Tech
Micron has announced it’s shipping 176-layer TLC NAND flash memory to customers, a move that portends larger, faster and even cheaper SSD drives for all. From a report: The company said its 5th-gen 3D NAND memory should put its density about 40 percent higher than its nearest competitors, which are using 128-layer NAND. Micron said read and write latencies are reduced…
NASA Confirms Water Molecules On Moon
NASA has confirmed the presence of water on the moon’s sunlit surface, a breakthrough that suggests the chemical compound that is vital to life on Earth could be distributed across more parts of the lunar surface than the ice that has previously been found in dark and cold areas. From a report: “We don’t know yet if we can use it…
Pliers smaller than an ant’s jaws are controlled by optical fibres
Microscopic filaments added to the end of optical fibres act as tiny pliers that can pick up objects just tens of microns in size Source: https://www.newscientist.com/article/2248589-pliers-smaller-than-an-ants-jaws-are-controlled-by-optical-fibres/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Covid-19 spreads through the air. That’s a big challenge for reopening

Spies Can Eavesdrop By Watching a Light Bulb’s Vibrations
An anonymous reader quotes a report from Wired: Researchers from Israeli’s Ben-Gurion University of the Negev and the Weizmann Institute of Science today revealed a new technique for long-distance eavesdropping they call “lamphone.” They say it allows anyone with a laptop and less than a thousand dollars of equipment — just a telescope and a $400 electro-optical sensor — to listen…
How coronavirus drifts through the air in microscopic droplets
Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.

New X-Ray Technique Images Soft-Tissue Tumors Clearer Than MRI
Researchers at Tohoku University have developed a new method of adapting X-ray to image soft tissue, “so that its higher resolution can reveal tumors or other problems earlier than other techniques,” reports New Atlas. From the report: Elastography is a field of medical imaging that focuses on the stiffness or softness of tissues. Shear waves are sent through the body, and…
