Expanding on the fundamental principles of liquid movement      (via sciencedaily.com)     Original source 

We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.

Zombie cells in the sea: Viruses keep the most common marine bacteria in check      (via sciencedaily.com)     Original source 

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean waters. A study now reveals that at times nearly 20% of SAR11 cells are infected by viruses, significantly reducing total cell numbers. The viruses can also transform these once thriving bacteria into zombies, a phenomenon observed for the first time and widespread in the oceans.

Airborne technology brings new hope to map shallow aquifers in Earth's most arid deserts      (via sciencedaily.com)     Original source 

The new technique will map the top of the aquifer, called the 'water table,' spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft. According to the researchers, Desert-SEA will measure the variabilities in the depth of the water table on a large scale, allowing water scientists to assess the sustainability of these aquifers without the limitations associated with in-situ mapping in harsh and inaccessible environments.

Study reveals consumers value animal welfare more than environmental sustainability when buying meat and dairy products      (via sciencedaily.com)     Original source 

The treatment of animals rates higher than green issues when consumers choose meat and dairy products. That's according to a new study, which suggests that while consumers consider sustainability important, other factors such as taste, quality, and animal welfare take precedence in their purchasing decisions.

'Forever chemicals' found to rain down on all five Great Lakes      (via sciencedaily.com)     Original source 

Perfluoroalkyl and polyfluoroalkyl substances, also known as PFAS or 'forever chemicals,' have become persistent pollutants in the air, water and soil. Because they are so stable, they can be transported throughout the water cycle, making their way into drinking water sources and precipitation. Precipitation introduces similar amounts of PFAS into each of the Great Lakes; however, the lakes eliminate the chemicals at different rates.
