Published Illuminating the molecular ballet in living cells
(via sciencedaily.com) Original source Researchers have developed one of the world's fastest cameras capable of detecting fluorescence from single molecules.
Published Viruses hidden in coral symbiont's genetic material are a potential threat to reefs
(via sciencedaily.com) Original source Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material.
Published Whales not to be counted on as 'climate savers'
(via sciencedaily.com) Original source Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.
Published CRISPR/Cas9 reveals a key gene involved in the evolution of coral skeleton formation
(via sciencedaily.com) Original source New work uses cutting-edge CRISPR/Cas9 genome editing tools to reveal a gene that's critical to stony corals' ability to build their reef architectures. This research could inform coral conservation and restoration efforts.
Published House of moveable wooden walls unveiled, promising a cheaper, greener alternative to 'knocking through'.
(via sciencedaily.com) Original source Architects have designed a prototype home constructed with flexible wooden partition walls which can be shifted to meet the changing needs of residents. The invention aims to reduce waste and carbon while also improving living conditions for those who cannot afford expensive refurbishments.
Published Unveiling the nanoscale frontier: innovating with nanoporous model electrodes
(via sciencedaily.com) Original source Researchers have introduced a next-generation model membrane electrode that promises to revolutionize fundamental electrochemical research.
Published Record 19.31% efficiency with organic solar cells
(via sciencedaily.com) Original source Researchers have achieved a breakthrough power-conversion efficiency (PCE) of 19.31% with organic solar cells (OSCs), also known as polymer solar cells. This remarkable binary OSC efficiency will help enhance applications of these advanced solar energy devices.
Published Biodegradable plastic from sugar cane also threatens the environment
(via sciencedaily.com) Original source Plastic made from cane sugar also threatens the environment. Researchers from the University of Gothenburg have found that perch change their behavior when exposed to so-called bioplastic.
Published Petit-spot volcanoes involve the deepest known submarine hydrothermal activity, possibly release CO2 and methane
(via sciencedaily.com) Original source Underwater volcanism and its hydrothermal activity play an important role in marine biogeochemical cycles, especially the carbon cycle. But the nature of hydrothermal activity at 'petit-spot' volcanoes have not been revealed at all. Now, scientists reveal that petit-spot hydrothermal activity occurs on the deepest seafloor known to date and could release carbon dioxide (CO2) and methane, which may have implications for the global carbon cycle.
Published PAINTing a wound-healing ink into cuts with a 3D-printing pen
(via sciencedaily.com) Original source The body is pretty good at healing itself, though more severe wounds can require bandages or stitches. But researchers have now developed a wound-healing ink that can actively encourage the body to heal by exposing the cut to immune-system vesicles. The ink can be spread into a cut of any shape using a 3D-printing pen, and in mice, the technology nearly completely repaired wounds in just 12 days.
Published The 'breath' between atoms -- a new building block for quantum technology
(via sciencedaily.com) Original source Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.
Published Newborn baby inspires sensor design that simulates human touch
(via sciencedaily.com) Original source As we move into a world where human-machine interactions are becoming more prominent, pressure sensors that are able to analyze and simulate human touch are likely to grow in demand.
Published Lab-grown mini lungs could accelerate the study of respiratory diseases
(via sciencedaily.com) Original source Researchers have collaborated to refine a cell culture technology platform that grows genetically identical lung buds from human embryonic stem cells.
Published You can make carbon dioxide filters with a 3D printer
(via sciencedaily.com) Original source Researchers demonstrated that it's possible to make carbon dioxide capture filters using 3D printing.
Published A protein mines, sorts rare earths better than humans, paving way for green tech
(via sciencedaily.com) Original source Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.
Published First X-ray of a single atom
(via sciencedaily.com) Original source Scientists have taken the world's first X-ray SIGNAL (or SIGNATURE) of just one atom. This groundbreaking achievement could revolutionize the way scientists detect the materials.
Published Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production
(via sciencedaily.com) Original source According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.
Published World's fastest electron microscope
(via sciencedaily.com) Original source Researchers have succeeded in filming the interactions of light and matter in an electron microscope with attosecond time resolution.
Published A nanocrystal shines on and off indefinitely
(via sciencedaily.com) Original source Optical probes have led to numerous breakthroughs in applications like optical memory, nanopatterning, and bioimaging, but existing options have limited lifespans and will eventually 'photobleach.' New work demonstrates a promising, longer-lasting alternative: ultra-photostable avalanching nanoparticles that can turn on and off indefinitely in response to near-infrared light from simple lasers.
Published Protecting large ocean areas doesn't curb fishing catches
(via sciencedaily.com) Original source In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.
