Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com)
Original source 
Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published Wildfire spread risk increases where trees, shrubs replace grasses
(via sciencedaily.com)
Original source 
A new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire perimeter.
Published Wiring up quantum circuits with light
(via sciencedaily.com)
Original source 
The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.
Published Study finds carrying pollen heats up bumble bees, raises new climate change questions
(via sciencedaily.com)
Original source 
A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.
Published We now know exactly what happens in nature when we fell forests
(via sciencedaily.com)
Original source 
Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.
Published Robotic proxy brings remote users to life in real time
(via sciencedaily.com)
Original source 
Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.
Published Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles
(via sciencedaily.com)
Original source 
Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. Collectively, these photosynthesizing plankton, or phytoplankton, absorb almost as much CO2 as the world’s terrestrial forests. A measurable fraction of their carbon-capturing muscle comes from Prochlorococcus — an emerald-tinged free-floater that is the most abundant phytoplankton in the oceans today. New research suggests the microbe's ancient coastal ancestors colonized the ocean by rafting out on chitin particles.
Published Invading insect could transform Antarctic soils
(via sciencedaily.com)
Original source 
A tiny flightless midge which has colonized Antarctica's Signy Island is driving fundamental changes to the island's soil ecosystem, a study shows.
Published Kangaroo Island ants 'play dead' to avoid predators
(via sciencedaily.com)
Original source 
They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.
Published Water warming study shows unexpected impact on fish size
(via sciencedaily.com)
Original source 
The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a new study.
Published Beetles and their biodiversity in dead wood
(via sciencedaily.com)
Original source 
Which energy type promotes the biodiversity of beetles living in dead wood in the forest? That depends entirely on where the beetles are in the food chain.
Published Exploring the underground connections between trees
(via sciencedaily.com)
Original source 
Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Published Small wildlife surveys can produce 'big picture' results
(via sciencedaily.com)
Original source 
Small-scale wildlife surveys can reveal the health of entire ecosystems, new research shows.
Published Viruses could reshuffle the carbon cycle in a warming world
(via sciencedaily.com)
Original source 
The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that viruses could alter carbon balance, causing some ecosystems to switch from net carbon sources to net carbon sinks.
Published A cocktail party of 3D-printed robot heads
(via sciencedaily.com)
Original source 
Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.
Published Archaea in a warming climate become less diverse, more predictable
(via sciencedaily.com)
Original source 
Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes
(via sciencedaily.com)
Original source 
Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published The future of data storage lies in DNA microcapsules
(via sciencedaily.com)
Original source 
Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
Published Vanishing glaciers threaten alpine biodiversity
(via sciencedaily.com)
Original source 
With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.
Published Indo-Pacific corals more resilient to climate change than Atlantic corals
(via sciencedaily.com)
Original source 
In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.
