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.

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.

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.

Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation      (via sciencedaily.com)     Original source 

Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.

Climate change is most prominent threat to pollinators      (via sciencedaily.com)     Original source 

A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.

First 'warm-blooded' dinosaurs may have emerged 180 million years ago      (via sciencedaily.com)     Original source 

The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
