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.

Analyzing androgynous characteristics in an emperor penguin courtship call      (via sciencedaily.com)     Original source 

In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin's male companion, E-81. The pair 'kept company' and sometimes exhibited ritual courtship displays. Researchers studied the courtship calls of E-79 and E-81, recording the birds in their below-freezing enclosure and refining the usual technique for analyzing the bursts.

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.
