Solar max is coming—the sun just released three X-class flares
The sun is increasing its intensity on schedule, continuing its approach to solar maximum. In just over a 24-hour period on May 5 and May 6, 2024, the sun released three X-class solar flares measuring at X1.3, X1.2, and X4.5. Solar flares can impact.....»»
Researchers discover three ingots made of Roman lead in Northern Córdoba
Three ingots from the site of Los Escoriales de Doña Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Córdoba. Measuring some 45 centimeters long and weighing between 24 and 32 ki.....»»
Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactions
The reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron.....»»
Free-forming organelles help plants adapt to climate change
Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery......»»
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.....»»
Rich molecular language guides tiny liquid droplet formation in cells
Peering into a biological cell reveals a bustling microscopic world. The workhorses within this realm are specialized structures called organelles that perform vital cellular functions. Curiously, some organelles defy accepted convention: Instead of.....»»
Researchers develop bioinspired Bouligand structure for enhanced mechanical properties
Bouligand structures, found in natural materials like fish scales, lobster peritoneum and bones, are known for providing exceptional mechanical properties to biomaterials. While progress has been made in creating bioinspired materials, most research.....»»
Listening to giants: The search for the elusive Antarctic blue whale
Blue whales are the largest animals on Earth, measuring up to 30 meters long and weighing up to 200 tons—as much as a Boeing 787. Yet it's the sound they make, not their size, which gives their location away......»»
Scientists directly measure a key reaction in neutron star binaries
An X-ray burst (XRB) is a violent explosion that occurs on the surface of a neutron star as it absorbs material from a companion star. During this absorption, increasing temperatures and densities on the surface of the neutron star ignite a cascade o.....»»
New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons......»»
Solar orbiter takes a mind-boggling video of the sun
You've seen the sun, but you've never seen the sun like this. This single frame from a video captured by ESA's Solar Orbiter mission shows the sun looking very fluffy! You can see feathery, hair-like structures made of plasma following magnetic field.....»»
Mayans burned and buried dead political regimes
After burning, the remains were dumped in construction fill. Enlarge / Mayans built impressive structures and occasionally put interesting items in the construction fill. (credit: Dr. Jürgen Tenckhoff) As civilizations.....»»
Twisting and binding matter waves with photons in a cavity
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it difficult to measure the posi.....»»
Two small NASA satellites will measure soil moisture, volcanic gases
Two NASA pathfinding missions were recently deployed into low-Earth orbit, where they are demonstrating novel technologies for observing atmospheric gases, measuring freshwater, and even detecting signs of potential volcanic eruptions......»»
Study unveils 3D printing PQD-polymer architectures at room temperature
A technology enabling the fabrication of intricate three-dimensional (3D) quantum dot (QD)-based structures at room temperature has been developed......»»
Study: Airway hillocks challenge our understanding of lung biology
Airway hillocks are mysterious, flat-topped structures that were only recently identified within regular lung tissue, and their role in airway biology and pathology has previously been unknown......»»
Neutron stars could be capturing primordial black holes
The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes.....»»
Microgravity-grown crystals reveal new insights into protein structures
Biochemists have long been working around a blind spot when it comes to proteins. They know that hydrogen constitutes nearly half of the atoms in proteins, but how they contribute to protein function in these complex structures has been less clear. H.....»»
AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes
Genome sequencing technology provides thousands of new plant genomes annually. In agriculture, researchers merge this genomic information with observational data (measuring various plant traits) to identify correlations between genetic variants and c.....»»
