How well do wet masks contain droplets?
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spr.....»»
Modeling Earth systems at a quintillion calculations per second
Climate models compute vast amounts of information about Earth's climate system—from small water droplets to large-scale weather patterns—to re-create past climate or predict future climate. Accurately re-creating how Earth's energy (measured in.....»»
Cloudflare once again comes under pressure for enabling abusive sites
Cloudflare masks the origin of roughly 10% of abusive domains, watchdog says. Enlarge (credit: Getty Images) A familiar debate is once again surrounding Cloudflare, the content delivery network that provides a free servi.....»»
Raindrops grow with turbulence in clouds: New findings could improve weather and climate models
Scientists for decades have attempted to learn more about the complex and mysterious chain of events by which tiny droplets in clouds grow large enough to begin falling toward the ground. Better understanding this process, known as the "rain formatio.....»»
Bursting of underwater oil drops: How pollution may remain in water after oil spill cleanups
Oil drops from underwater oil spills can break into tinier droplets at the surface that remain suspended in the water, according to research from the University of Illinois Chicago. That means cleanups after disasters like the Deepwater Horizon spill.....»»
MKULTRA: Making On The Down-Low
Last year at Maker Faire Bay Area on Mare Island, we came home with a picture of two awesomely masked makers. We put out a call in our Maker Faire newsletter hoping to elicit the evidently skilled makers behind these fanciful masks (see middle belo.....»»
Droplets that swim toward dissolution could inspire fluid microbots
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop fluid micro robots......»»
New method can create aquatic levitation at much lower temperature, has implications for cooling nuclear reactors
Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface......»»
At least 21 police injured, 16 arrested in violent protests at Tesla"s plant in Germany
A video showed dozens of people wearing blue caps and face-covering masks coming from a nearby wooded area and attempting to storm the company's premises with policemen trying to prevent them......»»

FTC fines Razer for every cent made selling bogus “N95 grade” RGB masks
“Deceptive advertising and misinformation posed a risk to public health." Enlarge (credit: Razer) The Federal Trade Commission (FTC) announced this week a proposed settlement [PDF] against Razer that would see the tec.....»»
Researchers develop tiny droplets that harness laser light to detect disease markers
A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has created tiny droplets that, when activated by laser light, can detect viral protein biomarkers indicating the presence of certain diseases......»»
Does wearing a face mask make you seem more or less trustworthy?
Researchers at Swinburne University of Technology have found that the correlation between face masks and perceptions of trustworthiness may be linked to social norms rather than how they impact appearance......»»
New single-cell analysis tech incorporates advanced fiber optics directly into microfluidic chips
Droplet microfluidics has revolutionized single-cell analysis, crucial for genomics, drug discovery, and diagnostics, by partitioning samples into nanoliter droplets for detailed cellular analysis. Yet, its broader adoption is hindered by the complex.....»»
Breaking the ice: Molecular insights into saltwater droplet freezing
In a new study, researchers have observed the freezing of saltwater droplets at a molecular level, offering new insights for de-icing and anti-icing technologies. Contrary to conventional wisdom, these droplets don't conform to the typical freezing p.....»»
Study demonstrates spontaneous self-organization of microdroplets through quasi one-dimensional confinement
Polymer systems composed of multiple components can spontaneously induce emulsion or microdroplets by mechanical mixing, as an intermediate state of macroscopic phase separation. Unfortunately, the size of generated droplets is nonuniform and their s.....»»
Study: Cicadas pee in jets, not droplets. Here’s why that’s kinda weird.
Come for the cicada video, stay for the scaling graphic of urination across animal kingdom. Cicadas' unique urination unlocks new understanding of fluid dynamics. Credit: Georgia Tech (Saad Bhamla/Elio Challita). Cicadas might be a.....»»
Optically trapped quantum droplets of light can bind together to form macroscopic complexes
Condensed matter systems and photonic technologies are regularly used by researchers to create microscale platforms that can simulate the complex dynamics of many interacting quantum particles in a more accessible setting. Some examples include ultra.....»»
Dancing droplets" new spin on water harvesting
A more efficient way to capture fresh water from the air could be inspired by a phenomenon of motion first glimpsed in bowls of breakfast cereal......»»
Helium droplets capture double water structure
An elusive structure involving two water molecules, which had been predicted but never observed, has been isolated by RIKEN chemists. This finding could have implications for a wide range of fields ranging from astrochemistry to corrosion of metals......»»
Pore power: High-speed droplet production in microfluidic devices
