Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat      (via sciencedaily.com)     Original source 

Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.

Complex green organisms emerged a billion years ago      (via sciencedaily.com)     Original source 

Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.

Scientists advance affordable, sustainable solution for flat-panel displays and wearable tech      (via sciencedaily.com)     Original source 

Scientists have developed 'supramolecular ink,' a new 3D-printable OLED (organic light-emitting diode) material made of inexpensive, Earth-abundant elements instead of costly scarce metals. The advance could enable more affordable and environmentally sustainable OLED flat-panel displays as well as 3D-printable wearable technologies and lighting.

Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows      (via sciencedaily.com)     Original source 

An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.

Towards the quantum of sound      (via sciencedaily.com)     Original source 

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.

Researchers create faster and cheaper way to print tiny metal structures with light      (via sciencedaily.com)     Original source 

Researchers have developed a light-based means of printing nano-sized metal structures that is 480 times faster and 35 times cheaper than the current conventional method. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. Their method is called superluminescent light projection (SLP).

Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird      (via sciencedaily.com)     Original source 

The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.

Light it up: Reimagining the optical diode effect      (via sciencedaily.com)     Original source 

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by passing light at shortwave infrared wavelengths used in optical communications. Furthermore, they have uncovered that it is possible to switch the optical diode effect by applying a magnetic field. This is a step forward in the development of an innovative optical isolator that is more compact and can control light propagation, replacing the conventional optical isolators with complex structures.

The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance      (via sciencedaily.com)     Original source 

Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.
