Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular networks that not only display the complexity and beauty of mono-component self-assembly on surfaces; they also exhibit exceptional properties.
UNIVERSITY PARK, Pa. -- Walnuts may not just be a tasty snack, they may also promote good-for-your-gut bacteria. New research suggests that these "good" bacteria could be contributing to the heart-health benefits of walnuts.
In a randomized, controlled trial, researchers found that eating walnuts daily as part of a healthy diet was associated with increases in certain bacteria that can help promote health. Additionally, those changes in gut bacteria were associated with improvements in some risk factors for heart disease.
While studies of the microbiomes (which comprises all the microorganisms, mainly bacteria and fungi) of the phyllosphere and the rhizosphere of plants are important, scientists at INRA believe more attention should be given to the microbiomes of crop residues.
Crop residues are important as a key microbial ecosystem with the power to contribute both negatively and positively to crop health and productivity. Crop residues are a breeding ground for plant disease but also contribute significantly to the stability of agrosystems.
Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. They even coined a term for it-- Magneto-elastoresistance, or MER.
Scientists in condensed matter physics at the U.S. Department of Energy's Ames Laboratory have a long history of investigating "weird" materials, according to Paul Canfield, Ames Lab physicist, Distinguished Professor and the Robert Allen Wright Professor of Physics and Astronomy at Iowa State University.
Tropical Cyclone Claudia was dissipating in the Southern Indian Ocean when NASA's Terra satellite captured a visible image of storm as it flew overhead in its orbit around the Earth.
On Jan. 15 at 4 p.m. EST (2100 UTC) the Joint Typhoon Warning Center (JTWC) noted in their final warning that Tropical Cyclone Claudia's maximum sustained winds were down to 35 knots (40 mph/65 kph). Claudia was far from land, near latitude 21.4 degrees south and longitude 104.8 degrees east, about 521 nautical miles west of Learmonth, Australia.
Fish sticks may be a tasty option for dinner, but are they good for the planet?
A new study of the climate impacts of seafood products reveals that the processing of Alaskan pollock into fish sticks, imitation crab, and fish fillets generates significant greenhouse gas emissions.
Post-catch processing generates nearly twice the emissions produced by fishing itself, which is typically where the analysis of the climate impact of seafood ends, according to the findings by researchers at the University of California, Santa Cruz.
Common medical imaging procedures use low doses of radiation that are believed to be safe. A new study, however, finds that in human cell cultures, these doses create breaks that allow extra bits of DNA to integrate into the chromosome. Roland Kanaar and Alex Zelensky of Erasmus University Medical Center and Oncode Institute and colleagues report these new findings in a study published 16th January in PLOS Genetics.
DALLAS, Jan. 16, 2019 - For the first time, in a study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke, according to new research published today in the American Heart Association's journal Arteriosclerosis, Thrombosis and Vascular Biology (ATVB).
A massive experiment that deployed regular police patrols on platforms in the London Underground has shown that four 15-minute patrols a day in some of the capital's most crime-ridden stations reduced reported crime and disorder by 21%.
LA JOLLA, CALIF. - January 16, 2020 - Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that cells from children with NGLY1 deficiency--a rare disorder first described in 2012--lack sufficient water channel proteins called aquaporins. The discovery was published in Cell Reports and may help explain the disorder's wide-ranging symptoms--including the inability to produce tears, seizures and developmental delays--and opens new avenues to find therapies to treat the disorder.
Deep-subwavelength acoustic absorbers have received great attention due to their scientific and application values. Porous materials and micro-perforated absorbers, as the most conventional solutions, generally possess a structural thickness comparable to working wavelength, which hinders their potentials in the low frequency region. The recent advance in acoustic metamaterial/metasurface brings forward perfect absorbers (resonators) that possess ultra-thin thickness but relatively narrow working frequency bandwidth.
A new study from Finland sheds fresh light on how melanoma cells interact with other cells via extracellular vesicles they secrete. The researchers found that extracellular vesicles secreted by melanoma cells use the so-called hedgehog signalling pathway to intensify the malignant properties of the cells they are targeting. The discovery can help in the development of better treatment and diagnostics for melanoma.
A new paper in The Condor: Ornithological Applications, published by Oxford University Press, finds that models which use terrain features offer both practical and theoretical advantages in identifying climate resilient habitats for migratory birds whose populations are impacted by climate change.
Philadelphia, January 16, 2020 - Rickettsiae are bacteria that cause severe, potentially lethal human infections, including Mediterranean spotted fever (MSF) and Rocky Mountain spotted fever. Delays in diagnosing and treating MSF can cause significant morbidity and mortality, due in part to the lack of a test for early detection.
To solve a problem, you must first see the problem. More than that, whatever fallout the problem is causing must be controlled while you solve it. That's the approach an international team of researchers has taken for combatting network attacks. They published their results in IEEE/CAA Journal of Automatica Sinica.
