A novel, efficient fog collector inspired by shorebirds' beaks has been developed, promising a sustainable solution for communities in arid regions. The device collects water from fog using a simple, rectangular design that mimics the shorebird's feeding mechanism.
A UT Arlington engineering professor and his doctoral student have designed a device based on a shorebird's beak that can accumulate water collected from fog and dew. The device could provide water in drought-stricken areas of the world or deserts around the globe, offering an alternative to current methods.
A recent study found a 46% drop in Central Valley wintertime fog days between November and February, which is crucial for fruit and nut crops. The researchers suggest climate forecasts indicate continued decline in winter chill accumulation, prompting farmers to consider adjusting orchard locations.
Researchers at the University of Bristol have developed a tabletop system called MisTable, which combines interactive personal screens with a fog-based interface. The system allows users to switch between interacting with individual screens and collaborating on tasks, promoting new forms of collaboration and interaction.
Researchers developed a method to analyze redwood cores for climate reconstruction, revealing 50-year coastal conditions. The technique uses oxygen isotopes to detect fog and rainfall, providing insights into ocean temperatures and long-term climate change.
The NASA-NOAA Suomi NPP satellite has released a global composite image that shows the glow of natural and human-made sources across the planet. The high-resolution images reveal valuable data for researchers studying weather conditions, such as fog and low clouds, that are difficult to detect with traditional sensors.
Researchers found elevated mercury levels in coastal fog due to upwelling of deep ocean water, which brings the element to the surface and into the atmosphere. While the levels are extremely low, more research is needed to understand the processes involved.
A new study published in Global Change Biology explores the impact of climate change on entire forest ecosystems through changes in cloud cover. The research found that altered cloud cover can lead to increased carbon cycling and tree growth due to fog drip, which provides essential water input to the soil.
Researchers found that mosquitoes struggle to fly in heavy fog, despite their ability to withstand raindrops. The study reveals that the tiny fog particles overwhelm the mosquito's gyroscopic sensors, leading to flight failure.
Fat, oil, and grease (FOG) harden into calcium-based fatty acid salts, creating deposits that reduce wastewater flow and cause environmental problems. Researchers have discovered the molecular mechanism behind FOG deposit formation using FTIR spectroscopy.
The first permanent anti-fog coating has been developed by researchers at Université Laval, eliminating the need for regular reapplication. The coating prevents water droplets from forming on surfaces, maintaining optical properties and durability.
A University of Washington scientist found that summertime coastal fog has declined and coastal temperatures have increased slightly since 1950. Climate models predict an increase in fog, but regional patterns may be overriding this effect.
The new fog warning system provides reliable services and saves socio-economic costs, with a forecasted cost-benefit ratio of 9.4, indicating it pays itself back ten times over within ten years. The system has demonstrated minimal service breaks and real-time functionality.
A European team of astronomers has confirmed that the UDFy-38135539 galaxy is the most remote object identified so far in the Universe. By analyzing its light's redshift, they found that it was seen just 600 million years after the Big Bang, providing valuable insights into the era of reionisation and galaxy formation.
Researchers found that ferns in the northern end of the redwood forest ecosystem are better equipped to absorb fog water than those in the southern region. This has important implications for the structure of plant communities and how ecosystems function during drought periods. The study suggests that native ferns may be able to acclim...
A study by University of California, Berkeley scientists found that California's coastal fog has decreased significantly over the past 100 years, from 56% to 42%, due to a decline in the coast-inland temperature gradient. This change may lead to drought-stress for redwood ecosystems and potentially impact recruitment of new trees.
