Published Achieving quantum memory in the hard X-ray range
(via sciencedaily.com) Original source Physicists have used Doppler-shifted nuclear resonant absorbers to form a nuclear frequency comb, enabling a quantum memory in the notoriously difficult X-ray range.
Published Glossy black-cockatoos prefer the fruits of ancient rocks
(via sciencedaily.com) Original source New research has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils.
Published Researchers make breakthrough in understanding species abundance
(via sciencedaily.com) Original source The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
Published 3D bioprinting advances research on respiratory viruses
(via sciencedaily.com) Original source Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Microscopy technique 'paves way' for improving understanding of cellular functions
(via sciencedaily.com) Original source Scientists have developed a new way of counting labelled proteins in living cells that could become a standard and valuable tool in the field of biomedical research.
Published Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity
(via sciencedaily.com) Original source A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
Published Recurrent wheezing in children linked to 'silent' viral infections
(via sciencedaily.com) Original source Nearly a quarter of children with recurrent wheezing have 'silent' lung infections that would be better treated with antiviral medications than commonly prescribed steroids that can carry lifelong side effects, new research reveals.
Published Asthma emergencies spike when allergenic pollen blooms
(via sciencedaily.com) Original source A new study that tracks how many asthma-related emergency room visits result from pollen in metropolitan areas highlights the importance of knowing local plants and the need for developing science-based pollen forecasts.
Published 3D-printed blood vessels bring artificial organs closer to reality
(via sciencedaily.com) Original source Lab-grown organs are a long-time 'holy grail' of organ engineering that has yet to be achieved, but new research has brought that goal a big step closer to reality using a new 3D-printing method called co-SWIFT. co-SWIFT prints branching networks of double-layered vessels that are infused with smooth muscle cells and endothelial cells into living human cardiac tissue, and can even replicate patient-specific vascular structures,indicating that it could one day be used for personalized medicine.
Published Viral defense protein speeds up female stem cell production
(via sciencedaily.com) Original source A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Individuals vary in how air pollution impacts their mood
(via sciencedaily.com) Original source Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
Published International Space Station crew carries out archeological survey in space
(via sciencedaily.com) Original source An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station -- and how this differs from intended uses.
Published Do smells prime our gut to fight off infection?
(via sciencedaily.com) Original source In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
Published When mammoths roamed Vancouver Island
(via sciencedaily.com) Original source Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.
Published Findings from first archaeology project in space
(via sciencedaily.com) Original source The first-ever archeological survey in space has provided new insights into how astronauts use and adapt their living space on the International Space Station, which could influence the design of new space stations after the ISS is decommissioned.
Published Scientists lay out revolutionary method to warm Mars
(via sciencedaily.com) Original source Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.
Published Cocaine discovery could pave way for treatment for substance abuse
(via sciencedaily.com) Original source Cocaine binds to a specific transporter in the brain that is responsible for regulating dopamine levels. Researchers have studied and described the process, producing new knowledge that may bring us a step closer to designing a drug for cocaine abuse.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing
(via sciencedaily.com) Original source Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published Turning unused signals such as Wi-Fi into energy for electronics
(via sciencedaily.com) Original source We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.
