In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is constant in vacuum - and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein's theory of General Relativity. The study has now been published in Physical Review Letters.
A deadly coronavirus pandemic, economic instability and civil unrest menace the mental well-being of millions. Understanding how, in vulnerable people, fear from such frightening events evolves into lifelong anxiety, is critical for healing.
A University of New Mexico research team led by Elaine L. Bearer, MD, PhD, the Harvey Family Professor in Pathology, and graduate student Taylor W. Uselman has identified for the first time brain-wide neural correlates of the transition from fear to anxiety.
Hilo, Hawai'i - For the first time, researchers have shown that native 'ohi'a seedlings can survive for at least a year in areas that have active mortality from Rapid 'ohi'a Death, or ROD, a fungal disease that is devastating to this dominant and culturally important tree in Hawaiian forests. This information can be useful to land managers and homeowners as they prioritize conservation actions.
ABERDEEN PROVING GROUND, Md. -- A new machine learning framework could pave the way for small, mobile quantum networks.
Researchers from the U.S. Army Combat Capabilities Development Command's Army Research Laboratory and Tulane University combined machine learning with quantum information science, or QIS, using photon measurements to reconstruct the quantum state of an unknown system.
COLUMBUS, Ohio - A new study might explain why humans register some tastes more quickly than others, potentially due to each flavor's molecular size.
The research, published last month in the journal PLOS Computational Biology, also provided explanation as to why humans register taste more quickly when food or drink moves over their tongues quickly, as compared to when they are held in their mouth steadily.
Researchers use a variety of modelling approaches to study form and function. By using a basic biomechanical model for studying body form and center of mass stability in ants, new research identifies the benefits of “simple models” and hope that it can be used for bio-inspired designs.
New research from the University of Virginia School of Medicine reveals how plants create the load-bearing structures that let them grow - much like how building crews frame a house.
Funded by the U.S. Department of Energy, the new discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called "microfibrils." These microfibrils provide crucial support to the cell walls of land plants and allow them to build up pressure inside their cells. This pressure lets plants grow towards the sky.
Common domestic cats, as we know them today, might have accompanied Kazakh pastoralists as pets more than 1,000 years ago. This has been indicated by new analyses done on an almost complete cat skeleton found during an excavation along the former Silk Road in southern Kazakhstan.
Aside from the deep understanding of the natural world that quantum physics theory offers, scientists worldwide are working tirelessly to bring forth a technological revolution by leveraging this newfound knowledge in engineering applications. Spintronics is an emerging field that aims to surpass the limits of traditional electronics by using the spin of electrons, which can be roughly seen as their angular rotation, as a means to transmit information.
The authors propose a new quantitative approach to better measure the crystal growth rate in supercooled liquids. The approach is based on a unique statistical algorithm used in molecular dynamics simulation.
Aardvarks occur across most of sub-Saharan Africa, but very few people have seen one, because they are solitary, mostly active at night, and live in burrows. They use their spade-like claws to build these burrows and to dig up ants and termites on which they feed. However, seeing aardvarks feeding in the day is becoming more common in the drier parts of southern Africa.
How does the use of mobile devices affect children's brains? A team from the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has conducted the first epidemiological study to explore the relationship between brain volume in preadolescents--more than 2,500 Dutch children--and different doses of radiofrequency electromagnetic fields (RF-EMF).
An expansive, multi-site ecology study led by UBC has uncovered new insights into the effects of climate change on the delicate food webs of the neotropics.
In research recently outlined in Nature, scientists across seven different sites throughout Central and South America replicated the extreme rainfall events predicted by climate change science. Using the insect larvae that live in the water trapped by bromeliad plants as a model ecosystem, they found that food webs became top-heavy with predators when there were large day-to-day variations in rainfall.
July 08, 2020 - Results of an analysis published in the Annals of the American Thoracic Society found that Black individuals were twice as likely as White individuals to test positive for COVID-19. The average age of all participants in the study was 46. However, those infected were on average 52 years old, compared to those who tested negative, who were 45 years old on average.
Scientists at Sanford Burnham Prebys Medical Discovery Institute have demonstrated the therapeutic potential of PRMT5 inhibitors to sensitize unresponsive melanoma to immune checkpoint therapy. PRMT5 inhibitors are currently in clinical trials in oncology, and this research provides a strong rationale for evaluating the drugs in tumors that are not responsive to immune checkpoint therapy.
