Using the shadows of clusters to measure the universe
Astronomers have begun using a sophisticated suite of simulations, an advanced machine learning model of the formation of galaxy clusters, and an exotic relationship between galaxies to understand the origins of dark matter and dark energy......»»
We need to consider conservation efforts on Mars, say researchers
Astrobiology is the field of science that studies the origins, evolution, distribution, and future of life in the universe. In practice, this means sending robotic missions beyond Earth to analyze the atmospheres, surfaces, and chemistry of extraterr.....»»
How aging clocks tick: New study points to stochastic changes in cells
Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from chronological age that is calculated using the date of birth. The precis.....»»
Probing neptunium"s atomic structure with laser spectroscopy
A new technique developed by researchers in Germany can measure ionization states of this element more precisely than before, with implications for its detection and remediation in radioactive waste......»»
CyberSaint releases NIST CSF Benchmarking Feature
CyberSaint released the NIST Cybersecurity Framework (CSF) Benchmarking Feature, which allows CISOs and security teams to measure their NIST posture against industry peers through a historical maturity graph on the CyberStrong Executive Dashboard. Or.....»»
Researchers can now accurately measure the emergence and damping of a plasmonic field
An international research team led by Universität Hamburg, DESY, and Stanford University has developed a new approach to characterize the electric field of arbitrary plasmonic samples, like, for example, gold nanoparticles. Plasmonic materials are o.....»»
As climate change amplifies urban flooding, here"s how communities can become "sponge cities"
"When it rains, it pours" once was a metaphor for bad things happening in clusters. Now it's becoming a statement of fact about rainfall in a changing climate......»»
New technology changes how proteins in individual cells are studied
Researchers from Karolinska Institutet, together with Pixelgen Technologies, have developed and applied a technique that makes it possible to map proteins in individual cells in a completely new way. Not only is it now possible to measure the amount.....»»
A triumph of galaxies in three new images from the VLT Survey Telescope
Distant galaxies, interacting galaxies, whose shape has been forged by the mutual gravitational influence, but also galaxies forming groups and clusters, kept together by gravity—they are the protagonists of three new images released by the VLT Sur.....»»
The universe could be filled with ultralight black holes that can"t die
Primordial black holes are hypothetical objects formed during the earliest moments of the universe. According to the models, they formed from micro-fluctuations in matter density and spacetime to become sand grain-sized mountain-massed black holes......»»
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.....»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
Radio astronomers bypass disturbing Earth"s atmosphere with new calibration technique
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Eart.....»»
These dangerous scammers don’t even bother to hide their crimes
Cybercriminals openly run dozens of scams across social media and messaging apps. Enlarge (credit: Kuzmik_A/Getty Images) Most scammers and cybercriminals operate in the digital shadows and don’t want you to know how.....»»
What Kind of Battery Would You Need to Power a Lightsaber?
On Star Wars Day, we use some basic physics to measure the power of the Force. It’s strong!.....»»
What can AI learn about the universe?
Artificial intelligence and machine learning have become ubiquitous, with applications ranging from data analysis, cybersecurity, pharmaceutical development, music composition, and artistic renderings......»»
Physicists pioneer new quantum sensing platform
Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ability to measure and d.....»»
The BREAD Collaboration is searching for dark photons using a coaxial dish antenna
Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques......»»
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......»»
Improved AI process could better predict water supplies
A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and o.....»»
