Published Researchers find new multiphoton effect within quantum interference of light
(via sciencedaily.com) Original source An international team of researchers has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g. sunlight) and parametric single photons (generated in non-linear crystals).
Published Three-year population study supports fight to save Cameroon's Kordofan giraffe
(via sciencedaily.com) Original source Crucial new data about the numbers of Critically Endangered Kordofan giraffe living within Cameroon's B nou National Park has been released, supporting conservation efforts to save the subspecies from extinction.
Published Blue tit population booms with moths on the menu
(via sciencedaily.com) Original source Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.
Published A new perspective on the temperature inside tropical forests
(via sciencedaily.com) Original source New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.
Published 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.
Published Planetary Commons: Fostering global cooperation to safeguard critical Earth system functions
(via sciencedaily.com) Original source Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.
Published 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.
Published New research sheds light on a phenomenon known as 'false vacuum decay'
(via sciencedaily.com) Original source Scientists have produced the first experimental evidence of vacuum decay.
Published A window into plant evolution: The unusual genetic journey of lycophytes
(via sciencedaily.com) Original source An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
Published 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.
Published How does one species become many?
(via sciencedaily.com) Original source A global team of biologists has compiled nearly two decades of field data -- representing the study of more than 3,400 Darwin's finches in the Galapagos Islands -- to identify the relationship between beak traits and the longevity of individual finches from four different species.
Published Sea otters helped prevent widespread California kelp forest declines over the past century
(via sciencedaily.com) Original source The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.
Published 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.
Published Why animals shrink over time explained with new evolution theory
(via sciencedaily.com) Original source The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published 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.
Published Chemists create a 2D heavy fermion
(via sciencedaily.com) Original source Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.
Published Higher measurement accuracy opens new window to the quantum world
(via sciencedaily.com) Original source A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
Published Long live the graphene valley state
(via sciencedaily.com) Original source Researchers found evidence that bilayer graphene quantum dots may host a promising new type of quantum bit based on so-called valley states.
Published Climate change threatens global forest carbon sequestration, study finds
(via sciencedaily.com) Original source Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Physicists identify overlooked uncertainty in real-world experiments
(via sciencedaily.com) Original source The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, researchers argue that uncertainty in the thermodynamic parameters themselves -- built into equations that govern the energetic behavior of the system -- may also influence the outcome of an experiment.
