Controlling water, transforming greenhouse gases      (via sciencedaily.com)     Original source 

Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.

Designing a better nest to help endangered turtles      (via sciencedaily.com)     Original source 

With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen. The researchers found that the design provided a more stable environment for incubating eggs compared to natural sites, where the probability of an egg hatching was only 10 per cent compared to 41 per cent in the created site.

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought      (via sciencedaily.com)     Original source 

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.

Escaped GMO canola plants persist long-term, but may be losing their extra genes      (via sciencedaily.com)     Original source 

Populations of canola plants genetically engineered to be resistant to herbicides can survive outside of farms, but may be gradually losing their engineered genes, reports a new study.

Improving statistical methods to protect wildlife populations      (via sciencedaily.com)     Original source 

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

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.

Can coal mines be tapped for rare earth elements?      (via sciencedaily.com)     Original source 

A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.

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.

Bees and butterflies on the decline in western and southern North America      (via sciencedaily.com)     Original source 

Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.

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.
