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......»»
Meteorites: Why study them? What can they teach us about finding life beyond Earth?
Universe Today has explored the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, and cosmochemistry, and how this myriad of intricately linked sci.....»»
Using a cellphone compass to measure tiny concentrations of compounds important for human health
Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers at the National Institute of Standards and Technolog.....»»
Astronomers only knew of a single binary Cepheid system—they just found nine more
Measuring the distance to far away objects in space can be tricky. We don't even know the precise distance to even our closest neighbors in the universe—the Small and Large Magellanic Clouds. But, we're starting to get to the tools to measure it. O.....»»
Cosmochemistry: Why study it? What can it teach us about finding life beyond Earth?
Universe Today has had some fantastic discussions with researchers on the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, and planetary geophysics, and how these diver.....»»
Marine protected areas safeguard more than ecology—they bring economic benefits to fisheries and tourism
Marine Protected Areas (MPAs) have been used as a conservation measure for decades, but critics continue to argue that evidence of their economic benefits is weak, particularly with regard to fisheries......»»
10 Stranger Things spinoffs we’d like to see after season 5
Since Netflix plans to expand the Stranger Things universe after season 5, they should consider these spinoff ideas that fans would love to see......»»
Climate change is messing with how we measure time: Study
Struggle to wrap your head around daylight savings? Spare a thought for the world's timekeepers, who are trying to work out how climate change is affecting Earth's rotation—and in turn, how we keep track of time......»»
Solar eclipse could scramble bird behavior
On April 8, the shadow of a total solar eclipse will race across North America. At the same time, researchers from the Cornell Lab of Ornithology and partners will be hurrying to measure the impact of daytime darkness on the movements of birds, bats,.....»»
New method to measure entropy production on the nanoscale
Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. An equation developed by researchers at Chalmers University of Technology in Sweden, and Heinrich Heine University Düsseldorf, now sheds new l.....»»
Large Language Models’ Emergent Abilities Are a Mirage
A new study suggests that sudden jumps in LLMs’ abilities are neither surprising nor unpredictable, but are actually the consequence of how we measure ability in AI......»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
NASA"s tiny BurstCube mission launches to study cosmic blasts
NASA's BurstCube, a shoebox-sized satellite designed to study the universe's most powerful explosions, is on its way to the International Space Station......»»
Astronomers find evidence that blue supergiant stars can be formed by the merger of two stars
An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our universe, called blue supergiants. Although these stars are commonly observed,.....»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
Investigating variation of fine root vessel traits in topological order within and across tropical tree species
Anatomical and hydraulic traits can indirectly and directly measure the transport capacity of a root, respectively. Exploring variation in root traits along topological orders within species is key to understanding functional shifts along root archit.....»»
Novel method to measure root depth may lead to more resilient crops
As climate change worsens global drought conditions, hindering crop production, the search for ways to capture and store atmospheric carbon causing the phenomenon has intensified. Penn State researchers have developed a new high-tech tool that could.....»»
Red teaming in the AI era
As AI gets baked into enterprise tech stacks, AI applications are becoming prime targets for cyber attacks. In response, many cybersecurity teams are adapting existing cybersecurity practices to mitigate these new threats. One such practice measure i.....»»
Monitoring and measuring biodiversity requires more than just numbers: Scientists advocate for change
Assessing wildlife populations, as well as understanding the dynamics of their numbers and distributions across various regions, is a critical measure known in science as abundance......»»
Planetary geophysics: What is it? What can it teach us about finding life beyond Earth?
Universe Today has examined the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, and planetary atmospheres, and how these intriguing scientific disciplines can help scientists and the public.....»»
The mystery of consciousness shows there may be a limit to what science alone can achieve
The progress of science in the last 400 years is mind blowing. Who would have thought we'd be able to trace the history of our universe to its origins 14 billion years ago? Science has increased the length and the quality of our lives, and the techno.....»»
