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.

Plants restrict use of 'Tipp-Ex proteins'      (via sciencedaily.com)     Original source 

Plants have special corrective molecules at their disposal that can make retrospective modifications to copies of genes. However, it would appear that these 'Tipp-Ex proteins' do not have permission to work in all areas of the cell, only being used in chloroplasts and mitochondria. A study has now explained why this is the case. It suggests that the correction mechanism would otherwise modify copies that have nothing wrong with them, with fatal consequences for the cell.

A new 'rule of biology' may have come to light, expanding insight into evolution and aging      (via sciencedaily.com)     Original source 

A molecular biologist may have found a new 'rule of biology.' The rule challenges long-held notions that most living organisms prefer stability over instability because stability requires less energy and fewer resources.

Otters, especially females, use tools to survive a changing world      (via sciencedaily.com)     Original source 

Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools -- most of whom are female -- are able to eat larger prey and reduce tooth damage when their preferred prey becomes depleted.

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.

Bioengineered enzyme creates natural vanillin from plants in one step      (via sciencedaily.com)     Original source 

Vanilla, the most widely used flavoring compound in confectionaries and cosmetics, gets its sweet flavor and aroma from the chemical compound -- 'vanillin'. However, the large-scale production of natural vanillin is impeded by the lack of microbial processes and enzymes which can commercially generate vanillin. Now, researchers have genetically engineered a novel enzyme which can convert ferulic acid from plant waste into vanillin in a one-step sustainable process.

What is the carbon footprint of a house in Japan?      (via sciencedaily.com)     Original source 

Researchers conducted a comprehensive analysis on the carbon footprint of constructing a wooden house in Japan. The team found that the estimated carbon footprint of a house in Japan is 38 tons of CO2, with the largest share coming from the electric power sector at 32% of all emissions. Other sectors included were pig iron production at 12% of total emissions; cement, road freight transport, and private power generation each covering 7%.

Carbon-capture batteries developed to store renewable energy, help climate      (via sciencedaily.com)     Original source 

Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
