Plate tectonics in the Archean: Observation versus interpretation
The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic......»»
Visual observation of photonic Floquet–Bloch oscillations
Recently, the exploration of Bloch oscillations (BOs) in periodically driven quantum systems, equivalent to "Floquet systems," has drawn tremendous attention because their exotic characteristics are profoundly distinct from those in static systems. S.....»»
Research presents 2D dipole orientation method for mapping cells
Due to the high transparency of cells, it is very difficult to observe the organelles within them. Biologists can label specific organelles for observation through fluorescence staining. This is somewhat analogous to being in an environment without l.....»»
Computer models suggest modern plate tectonics are due to blobs left behind by cosmic collision
A small team of geologists and seismologists at the California Institute of Technology has found evidence via computer modeling that suggest giant blobs of material near the Earth's core, believed to have been created by a cosmic collision 4.5 billio.....»»
Researchers show that slow-moving earthquakes are controlled by rock permeability
Earthquakes are the most dramatic and noteworthy results of tectonic plate movement. They are often destructive and deadly, or at the very least physically felt—they're literally groundbreaking geological events. However not all tectonic movement r.....»»
Seeing is believing: Observation of migrasomes
Migrasomes, novel organelles first reported by Professor Li Yu' s team in 2015, are vesicular structures with diameters ranging from 0.5 to 3 micrometers that form on the retraction fibers at the rear of migrating cells. These structures contain vari.....»»
Animal behavior research better at keeping observer bias from sneaking in—but there"s still room to improve
Animal behavior research relies on careful observation of animals. Researchers might spend months in a jungle habitat watching tropical birds mate and raise their young. They might track the rates of physical contact in cattle herds of different dens.....»»
Tracking the dynamics of biomolecules with optofluidic antennas
In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current techniques based on fluorescence measurements in aqueous solutions.....»»
Smart vest turns fish into underwater spies, providing a glimpse into aquatic life like never before
Traditional techniques for observing fish behavior, largely dependent on vision-based systems, face substantial limitations, such as a confined range of observation and a limited duration of operation underwater. In response to these challenges, a re.....»»
First observation of photons-to-taus in proton–proton collisions
In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using.....»»
How did nervous systems, with their incredible complexity, evolve across different species?
New research supported by the Wu Tsai Neurosciences Institute's Interdisciplinary Postdoctoral Scholars program zeroes in on the surprising observation that many genes found in brain cells and synapses—the points of communication between neurons—.....»»
Australia must lead the world on nature restoration through ambitious interpretation of international law
Australia has a once-in-a-generation opportunity to halt and reverse biodiversity loss through ambitious law and policy reform......»»
One impact on Mars produced more than 2 billion secondary craters, finds study
There are plenty of craters on Mars, especially when compared to Earth. That is primarily thanks to the lack of weathering forces and strong plate tectonics that disrupt the formations of such impacts on our home planet. However, not all impact crate.....»»
NASA"s Swift temporarily suspends science operations
On March 15, NASA's Neil Gehrels Swift Observatory entered into safe mode, temporarily suspending science operations due to degrading performance from one of its three gyroscopes (gyros), which are used to point the observatory for making observation.....»»
Seismological study shows ancient lower mantle flow field under Philippine sea plate
Researchers from China and Japan have discovered distinct characteristics of Earth's lower mantle flow field. They investigated seismic anisotropy in the upper part of the lower mantle beneath the Philippine Sea Plate (PSP) and found that the ancient.....»»
Video: New radar mission for Europe
The upcoming Copernicus Radar Observation System for Europe in L-band (ROSE-L) will provide continuous day-and-night all-weather monitoring of Earth's land, oceans and ice, and offer frequent observations of Earth's surface at a high spatial resoluti.....»»
Weird electron behavior gets even weirder: Charge fractionalization observed spectroscopically
A research team led by the Paul Scherrer Institute has spectroscopically observed the fractionalization of electronic charge in an iron-based metallic ferromagnet. Experimental observation of the phenomenon is not only of fundamental importance. Sinc.....»»
Integrating software supply chain security in DevSecOps CI/CD pipelines
NIST released its final guidelines for integrating software supply chain security in DevSecOps CI/CD pipelines (SP 800-204D). In this Help Net Security video, Henrik Plate, Security Researcher at Endor Labs, talks about this report, which provides ac.....»»
Mars had its own version of plate tectonics
Plate tectonics is not something most people would associate with Mars. In fact, the planet's dead core is one of the primary reasons for its famous lack of a magnetic field. And since active planetary cores are one of the primary driving factors of.....»»
Better neutron mirrors can reveal the inner secrets of matter
Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the European Spallation Source. The improved mirror has been developed by researchers at Linköping University by coating a silicon plate with extrem.....»»
Heritage ERS-2 satellite returns to Earth
Launched in 1995, ERS-2 was a pioneering Earth observation satellite that greatly influenced our understanding of our planet and climate change. Despite an intended operational life of only three years, the satellite had a 16-year operational lifetim.....»»
