Published New technique may help scientists stave off coral reef collapse
(via sciencedaily.com) Original source Producing coral skeleton components in the easy-to-use soft-bodied sea anemone Nematostella creates a perfect lab system for studying, and eventually helping, corals threatened by a changing climate.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Eight new deep-sea species of marine sponges discovered
(via sciencedaily.com) Original source Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
Published Scientists raise the alarm: Too many harbour porpoises die each year in fishing nets
(via sciencedaily.com) Original source In order to keep the population of harbour porpoises in Danish coastal waters stable, only 24 can perish in fishing nets each year. However, over 900 die each year.
Published Powerless mechanoluminescent touchscreen underwater
(via sciencedaily.com) Original source Scientists have developed an optical display based on mechano-optical mechanisms.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Making quantum bits fly
(via sciencedaily.com) Original source Physicists are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits 'fly'.
Published Compact chips advance precision timing for communications, navigation and other applications
(via sciencedaily.com) Original source Precision timing and synchronization are crucial for navigation, communication and radar systems. Scientists have built compact chips capable of converting light into microwaves, which could improve these systems. This technology shrinks a tabletop system into a chip-sized format, reducing power usage and making it more applicable for use in everyday devices.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published New deep-sea worm discovered at methane seep off Costa Rica
(via sciencedaily.com) Original source Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.
Published Aluminum nanoparticles make tunable green catalysts
(via sciencedaily.com) Original source A nanotechnology pioneer has uncovered a transformative approach to harnessing the catalytic power of aluminum nanoparticles by annealing them in various gas atmospheres at high temperatures.
Published Using light to precisely control single-molecule devices
(via sciencedaily.com) Original source Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms
(via sciencedaily.com) Original source Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era
(via sciencedaily.com) Original source Fossils of a strange new species of marine lizard with dagger-like teeth that lived 66 million years ago, show a dramatically more biodiverse ocean ecosystem to what we see today.
Published New cardiovascular imaging approach provides a better view of dangerous plaques
(via sciencedaily.com) Original source Researchers have developed a new catheter-based device that combines two powerful optical techniques to image the dangerous plaques that can build up inside the arteries that supply blood to the heart. By providing new details about plaque, the device could help clinicians and researchers improve treatments for preventing heart attacks and strokes.
Published Spontaneous curvature the key to shape-shifting nanomaterials
(via sciencedaily.com) Original source Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
Published Opening a window on the brain
(via sciencedaily.com) Original source Researchers have introduced a new method for in vivo brain imaging, enabling large-scale and long-term observation of neuronal structures and activities in awake mice. This method is called the 'nanosheet incorporated into light-curable resin' (NIRE) method, and it uses fluoropolymer nanosheets covered with light-curable resin to create larger cranial windows.
Published A key to the future of robots could be hiding in liquid crystals
(via sciencedaily.com) Original source Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.
Published Researchers use liquid crystals to control polarization inside laser-written waveguides
(via sciencedaily.com) Original source Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable electro-optical control of polarization, which could open new possibilities for chip-based devices and complex photonic circuits based on femtosecond-written waveguides.
