An enormous new image of the ghostly Vela supernova remnant shows off the fascinating and elaborate structure of this striking cosmic object......»»
AI for astrophysics: Algorithms help chart the origins of heavy elements
The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time......»»
Paper offers a mathematical approach to modeling a random walker moving across a random landscape
Tiny particles like pollen grains move constantly, pushed and pulled by environmental forces. To study this motion, physicists use a "random walk" model—a system in which every step is determined by a random process. Random walks are useful for stu.....»»
Dark Energy Camera captures remains of a massive star that exploded nearly 11,000 years ago in huge gigapixel image
This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails).....»»
A coral superhighway in the Indian Ocean
New research has revealed that, despite being scattered across more than a million square kilometers, remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modeling, researchers at Oxford University ha.....»»
Giving particle detectors a boost: New device acts like a superconductivity switch
In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors in these facilities use s.....»»
Enhancing identifiability in plant growth models: A comprehensive framework for precision and reliability
In the evolving landscape of plant growth modeling, there is a distinguished presence of mechanistic models aimed at capturing the intricate dynamics of plant development through parameter estimation from experimental data. However, these models face.....»»
Statisticians and physicists team up to bring a machine learning approach to mining of nuclear data
Physicists use theoretical models to study physical quantities, such as the mass of nuclei, where they do not have experimental data. However, using a single imperfect theoretical model can lead to misleading results. To improve the quality of extrap.....»»
Scientists develop new machine learning method for modeling chemical reactions
Researchers from Carnegie Mellon University and Los Alamos National Laboratory have used machine learning to create a model that can simulate reactive processes in a diverse set of organic materials and conditions......»»
Scientists once again confirm giant asteroid Apophis won’t hit Earth in 2029
Following NASA’s D.A.R.T. mission revelation that asteroid paths could be changed based on collisions, scientists went back to the drawing board to further confirm that … The post Scientists once again confirm giant asteroid Apophis won&#.....»»
We know the Arctic is warming—what will changing river flows do to its environment?
Scientists at the University of Massachusetts Amherst recently combined satellite data, field observations, and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 year.....»»
Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013......»»
Modeling the origins of life: New evidence for an "RNA World"
Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, allowing slight variations.....»»
Unlocking the heat in mosquito modeling: Exploring disease transmission under climate change
Thermal adaptation is the ability of organisms to adjust their life history traits as the temperature changes. In the case of mosquitoes, these traits can determine their risk of transmitting mosquito-borne diseases and how this risk might change in.....»»
Step aside, internal tides: Supercomputer modeling improves satellite altimetry precision
Waves don't take place just on the ocean's surface. Underneath the crests and troughs that we can see from above are internal tides, which form when tidal flows collide with seamounts, continental slopes, and ridges on the seafloor......»»
Daily Telescope: Finally, we’ve found the core of a famous supernova
In the astronomy community, SN 1987A has somewhat legendary status. Enlarge / Webb has observed the best evidence yet for emission from a neutron star at the site of Supernova 1987A. (credit: NASA, ESA, CSA, STScI, et. al.).....»»
