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.

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.

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.

Scientists want to know how the smells of nature benefit our health      (via sciencedaily.com)     Original source 

Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.

A novel multifunctional catalyst turns methane into valuable hydrocarbons      (via sciencedaily.com)     Original source 

The optimal design of a novel zeolite catalyst enables tandem reaction that turns greenhouse gases into value-added chemicals, report scientists. By tuning the separation between different active sites on the catalyst, they achieved the stepwise conversion of methane into methanol and then to hydrocarbons at mild conditions. These findings will help reduce energy costs and greenhouse gas emissions across various industrial fields.
