Seeking medical insights in the physics of mucus      (via sciencedaily.com)     Original source 

Understanding how mucus changes, and what it changes in response to, can help diagnose illnesses and develop treatments. Researchers develop a system to grow mucus-producing intestinal cells and study the characteristics of the mucus in different conditions. The process involves growing a layer of intestinal cells on a laboratory plate exposed to air. These cells produce a layer of mucus that the researchers can easily access for testing. Using a magnetic wire, they can measure the consistency of the mucus without affecting its properties, and the platform can explore the effects of pathogens and help develop medications to combat them.

Millions in costs due to discharge of scrubber water into the Baltic Sea      (via sciencedaily.com)     Original source 

Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study shows that these emissions caused pollution corresponding to socio-economic costs of more than EUR 680 million between 2014 and 2022. At the same time, the researchers note that the shipping companies' investments in the much-discussed technology, where exhaust gases are 'washed' and discharged into the sea, have already been recouped for most of the ships. This means that the industry is now making billions of euros by running its ships on cheap heavy fuel oil instead of cleaner fuel.

Venus has almost no water: A new study may reveal why      (via sciencedaily.com)     Original source 

Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.

Turbid waters keep the coast healthy      (via sciencedaily.com)     Original source 

To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.

The Clues for Cleaner Water      (via sciencedaily.com)     Original source 

By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.

Astronomers observe elusive stellar light surrounding ancient quasars      (via sciencedaily.com)     Original source 

Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.

Lake tsunamis pose significant threat under warming climate      (via sciencedaily.com)     Original source 

The names might not be familiar -- Cowee Creek, Brabazon Range, Upper Pederson Lagoon -- but they mark the sites of recent lake tsunamis, a phenomenon that is increasingly common in Alaska, British Columbia and other regions with mountain glaciers. Triggered by landslides into small bodies of water, most of these tsunamis have occurred in remote locations so far, but geologists say it may just be a matter of time before a tsunami swamps a more populated place.

Did a magnetic field collapse trigger the emergence of animals?      (via sciencedaily.com)     Original source 

Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.

For microscopic organisms, ocean currents act as 'expressway' to deeper depths      (via sciencedaily.com)     Original source 

Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.

Oil palm plantations are driving massive downstream impact to watershed      (via sciencedaily.com)     Original source 

The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.

Random robots are more reliable      (via sciencedaily.com)     Original source 

New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.

This highly reflective black paint makes objects more visible to autonomous cars      (via sciencedaily.com)     Original source 

Driving at night might be a scary challenge for a new driver, but with hours of practice it soon becomes second nature. For self-driving cars, however, practice may not be enough because the lidar sensors that often act as these vehicles' 'eyes' have difficulty detecting dark-colored objects. New research describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.
