Scientists observe longitudinal plasmonic field in nanocavity at subnano-scale
A group of scientists working on surface-enhanced Raman spectroscopy (SERS) has made a nanoruler to provide insight into the longitudinal plasmonic fields in nanocavities, according to research published in the Journal of the American Chemical Societ.....»»
Rampant wildfires once led to global mass extinction, scientists say. Can it happen again?
A long time ago, the carbon was rock, buried in the earth as securely as a secret. Then an environmental catastrophe of unprecedented scale began. The rocks burned, and the atoms inside them disassembled into carbon dioxide and other greenhouse gases.....»»
Imaging solves mystery of how large HIV protein functions to form infectious virus
Understanding how HIV replicates within cells is key for developing new therapies that could help nearly 40 million people living with HIV globally. Now, a team of scientists from the Salk Institute and Rutgers University have for the first time dete.....»»
Snow At One of World"s Highest Observatories Melting Earlier Than Ever Before
An anonymous reader quotes a report from The Guardian: The snow at the highest observatory in the world to be operated all-year-round is expected to completely melt in the next few days, the earliest time on record. Scientists at the Sonnblick observ.....»»
Spintronics: Giant Rashba semiconductors show unconventional dynamics with potential applications
Germanium telluride is a strong candidate for use in functional spintronic devices due to its giant Rashba-effect. Now, scientists at HZB have discovered another intriguing phenomenon in GeTe by studying the electronic response to thermal excitation.....»»
Sub-angstrom noninvasive imaging of atomic arrangement in 2D hybrid perovskites
National University of Singapore scientists have demonstrated the non-invasive imaging of both the organic layers and underlying inorganic lattice of two-dimensional (2D) hybrid perovskites at the sub-angstrom level......»»
Rocks unravel the secrets of the Earth"s magnetic field
More than 350 million years ago something odd was going on with the Earth's magnetic field. Scientists now propose that the field was really weak, which may have affected life on our planet......»»
Gecko feet are coated in an ultra-thin layer of lipids that help them stay sticky
Geckos are famous for having grippy feet that allow them to scale vertical surfaces with ease. They get this seeming superpower from millions of microscopic, hairlike structures on their toes......»»
Researchers expand understanding of vortex spread in superfluids
An international team of scientists featuring Florida State University researchers has developed a model that predicts the spread of vortices in so-called superfluids, work that provides new insight into the physics that govern turbulence in quantum.....»»
New research challenges long-held beliefs about limb regeneration
Ken Muneoka is no stranger to disrupting the field of regeneration; for example, in a 2019 ground-breaking publication in Nature, the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVMBS) professor proved for the first tim.....»»
Scientists uncover novel aspects of HIV infection by monitoring sugars at the surface of individual immune cells
HIV researchers have long been trying to identify the specific cells that the virus prefers to infect and hide in. They know that HIV favors a special type of immune cells called memory CD4 T cells. But these cells come in many flavors, and it has be.....»»
Making it easier to differentiate mirror-image molecules
Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from P.....»»
A low temperature nanoparticle ink
A simple and versatile nanoparticle ink could help next-generation perovskite solar cells to be printed at scale and become the dominant force in commercial photovoltaics......»»
Europe"s most recent fossil of giant tortoise discovered
An international team of scientists, including Uwe Fritz and Christian Kehlmaier from Senckenberg, has made an astonishing discovery in the Zubbio di Cozzo San Pietro cave in Sicily, a burial site from the Copper/Bronze Age: bones of a giant tortoise.....»»
New advances in the search for molecular magnets
Scientists from the University of Lisbon (Portugal) and the University of Stuttgart (Germany) have managed to synthesize and extensively characterize a series of cobalt molecules that exhibit the properties of molecular magnets, an encouraging result.....»»
Robotic ammonites recreate ancient animals" movements
In a university swimming pool, scientists and their underwater cameras watch carefully as a coiled shell is released from a pair of metal tongs. The shell begins to move under its own power, giving the researchers a glimpse into what the oceans might.....»»
First long-term evidence of microplastic pollution from deep water layers of the open ocean
For the first time, scientists from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) analyzed a long-term sample series on microplastic pollution in the Northeast Atlantic from 2000 m water depth with respect to number, size, mass, mat.....»»
Novel NASA instrument sets sights on earthbound solar radiation
A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the sun and helping scientists understand how that energy influences our planet's severe weather, climate change and other global forces......»»
Hubble delves into cosmic treasure trove
This image from the NASA/ESA Hubble Space Telescope captures the sparkling globular cluster NGC 6569 in the constellation Sagittarius. Hubble explored the heart of this cluster with both its Wide Field Camera 3 and Advanced Camera for Surveys, reveal.....»»
Greater insight into the pinning effects of skyrmions
When researchers use an optical Kerr microscope to zoom in on thin films of magnetic material, given the right conditions, they observe a sort of micro-scale magnetic hurricane. Physicists call these whirlwind-like magnetic structures skyrmions. The.....»»
