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.

Planet hunters unveil massive catalog of strange worlds      (via sciencedaily.com)     Original source 

While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.

Potentially habitable 'exo-Venus' with Earth-like temperature discovered      (via sciencedaily.com)     Original source 

Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.

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.

Community science volunteers can set scientific world abuzz with new bumble bee sightings      (via sciencedaily.com)     Original source 

Community science volunteers -- laypeople with an interest in bees and conservation -- significantly contribute to the scientific knowledge of native bumble bees across Canada and the United States. It's buzz worthy confirmation that community science programs can play an important role in monitoring the changing distributions of bumble bees and more.

Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time      (via sciencedaily.com)     Original source 

Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their evolution across the universe.

Roots are a key to drought-tolerant maize      (via sciencedaily.com)     Original source 

Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant's ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change.

How plants 'mate' for life and repel other suitors      (via sciencedaily.com)     Original source 

Researchers have used a unique microscopic technique to examine the dynamics of pollen tubes in the Arabidopsis plant. They were able to observe the mechanism of one-to-one pollen tube guidance, a process that ensures successful pollination of plants. This process is influenced by multi-step repelling and attracting signals. The results are important for the cultivation of crops, especially under unfavorable environmental conditions.

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.

A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food      (via sciencedaily.com)     Original source 

A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.

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.

The impacts of climate change on food production      (via sciencedaily.com)     Original source 

A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.

Modern plant enzyme partners with surprisingly ancient protein      (via sciencedaily.com)     Original source 

Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.

Scientists discover mechanism of sugar signaling in plants      (via sciencedaily.com)     Original source 

A paper describes how the moving parts of a particular plant protein control whether plants can grow and make energy-intensive products such as oil -- or instead put in place a series of steps to conserve precious resources. The study focuses specifically on how the molecular machinery is regulated by a molecule that rises and falls with the level of sugar -- plants' main energy source.

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.
