Is the Amazon forest approaching a tipping point?      (via sciencedaily.com)     Original source 

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.

Frequent marine heatwaves in the Arctic Ocean will be the norm      (via sciencedaily.com)     Original source 

Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new study.

Scientists create effective 'spark plug' for direct-drive inertial confinement fusion experiments      (via sciencedaily.com)     Original source 

Scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. These results demonstrate an effective 'spark plug' for direct-drive methods of inertial confinement fusion.

Physicists develop highly robust time crystal      (via sciencedaily.com)     Original source 

Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.

Climate change threatens older elephants most, jeopardizing African elephants' future      (via sciencedaily.com)     Original source 

A collaborative team of researchers has conducted first-of-its kind research into how global climate change affects African elephants. The work shows that older elephants will have markedly decreased chances of survival, which will not only drastically reduce the species' overall ability to weather the changing climate but will send ripple effects throughout the surrounding landscape. The team has also modeled possible mitigation scenarios.

Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries      (via sciencedaily.com)     Original source 

Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.

Use it or lose it: How seagrasses conquered the sea      (via sciencedaily.com)     Original source 

Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.

Liquid lithium on the walls of a fusion device helps the plasma within maintain a hot edge      (via sciencedaily.com)     Original source 

Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as it's better suited for use in a large-scale tokamak.

Gravity helps show strong force strength in the proton      (via sciencedaily.com)     Original source 

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.

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.

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.

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.

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.
