Genes provide hope for the survival of Arabia's last big cat      (via sciencedaily.com)     Original source 

The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in Oman, the research team discovered higher levels of genetic diversity in captive leopards across the region. This important genetic resource has the potential for a major role in successful recovery of the Arabian leopard.

By listening, scientists learn how a protein folds      (via sciencedaily.com)     Original source 

By converting their data into sounds, scientists discovered how hydrogen bonds contribute to the lightning-fast gyrations that transform a string of amino acids into a functional, folded protein. Their report offers an unprecedented view of the sequence of hydrogen-bonding events that occur when a protein morphs from an unfolded to a folded state.

Blueprints of self-assembly      (via sciencedaily.com)     Original source 

Scientists have taken a step closer to replicating nature's processes of self-assembly. The study describes the synthetic construction of a tiny, self-assembled crystal known as a 'pyrochlore,' which bears unique optical properties. The advance provides a steppingstone to the eventual construction of sophisticated, self-assembling devices at the nanoscale -- roughly the size of a single virus.

Cooperative hunting requires less brainpower than previously thought      (via sciencedaily.com)     Original source 

Through the use of artificial intelligence technology, a team of scientists has shown that advanced cognitive abilities are unnecessary for cooperative hunting. Their findings suggest that cooperative hunting, previously thought to be a complex social behavior seen primarily in mammals such as lions and chimpanzees, can also develop in species with lower levels of cognitive ability.

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.

Breaking bonds to form bonds: Rethinking the Chemistry of Cations      (via sciencedaily.com)     Original source 

A team of chemists has achieved a significant breakthrough in the field of chemical synthesis, developing a novel method for manipulating carbon-hydrogen bonds. This groundbreaking discovery provides new insights into the molecular interactions of positively charged carbon atoms. By selectively targeting a specific C--H bond, they open doors to synthetic pathways that were previously closed -- with potential applications in medicine.

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.

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.

Tiger beetles fight off bat attacks with ultrasonic mimicry      (via sciencedaily.com)     Original source 

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.

Parasitic worm likely playing role in decline of moose populations      (via sciencedaily.com)     Original source 

A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America. Moose populations have been dwindling for years across the country due to many contributing factors, but new research has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.
