Gravitational waves may have made human life possible
Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research team headed by John R. Ellis of Kings College Lond.....»»
"Shear sound waves" provide the magic for linking ultrasound and magnetic waves
A team led by researchers from the RIKEN Center for Emergent Matter Science in Japan has succeeded in creating a strong coupling between two forms of waves—magnons and phonons—in a thin film. Importantly, they achieved this at room temperature, o.....»»
Comprehensive study explores influence of gene expression on primate brain evolution
An interdisciplinary team of researchers led by biologists at the University of Massachusetts Amherst recently published the results of a first-of-its-kind study investigating the links between gene expression and brain evolution across 18 primate sp.....»»
Study finds decline in the stability of water yield in watersheds
Extreme climatic events such as droughts, heat waves, and cold spells not only modify hydro-meteorological conditions but also alter the underlying characteristics (e.g., wildfires due to droughts changing the vegetation cover). Intense human activit.....»»
Enhancing fire safety: The emergence of PA-DAD as a sustainable flame retardant for epoxy resin composites
Epoxy resin (EP), an essential material in various applications such as adhesives, coatings, and composites, faces challenges due to its intrinsic flammability and dense smoke production, posing threats to safety and property. To address these issues.....»»
Tasmania"s tall eucalypt forests will be wiped out by heat waves unless we step in to help them
Tasmania's tall eucalypt forests are globally significant. They accumulate carbon faster than any other natural forest ecosystem in the world......»»
Gurman: In-house Apple Watch display project canceled, but microLED products still expected
Spring cleaning continues at Apple. Per Mark Gurman at Bloomberg, Apple no longer plans to design and produce its own displays for the Apple Watch. Apple has reportedly been investigating moving from OLED to custom microLED screens dates since at lea.....»»
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.....»»
Climate change is speeding up in Antarctica
In recent years, Antarctica has experienced a series of unprecedented heat waves. On 6 February 2020, temperatures of 18.3°C were recorded, the highest ever seen on the continent, beating the previous record of 17.5°C which had only been set a few.....»»
Planet "on the brink", with new heat records likely in 2024: UN
Global temperatures "smashed" heat records last year, as heat waves stalked oceans and glaciers suffered record ice loss, the United Nations said Tuesday—warning 2024 was likely to be even hotter......»»
Hubble views dwarf galaxy LEDA 4216
This NASA/ESA Hubble Space Telescope image shows LEDA 42160, a galaxy about 52 million light-years from Earth in the constellation Virgo. The dwarf galaxy is one of many forcing its way through the comparatively dense gas in the massive Virgo cluster.....»»
Investigating the many flavors of edible ants
Insects are typically unwelcome visitors to a picnic, but they could be a flavorful, nutritious and sustainable addition to the menu. Eating insects is common in some parts of the world, and some species are even considered delicacies......»»
Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication......»»
Advances and challenges in understanding compound weather and climate extremes
In the context of global warming, many extremes, such as heat waves, heavy precipitation, and droughts, have become increasingly frequent and intense, as expected theoretically. Somewhat unexpectedly, these extremes have also exhibited tightened link.....»»
Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
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......»»
Gravity waves caused by complex terrain over the Tibetan Plateau can enhance the intensity of spring rainfall
The springtime persistent rainfall is the major rainy period before the onset of summer monsoon in East Asia. For example, it accounts for about 35% of the annual precipitation in South China, which brings plentiful water for agricultural and industr.....»»
AI making waves in marine data collection
Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly.....»»
Unprecedented Hauraki Gulf heat waves revealed by marine lab"s historic data set
A thermometer dipped in a bucket of sea water on New Year's Day in 1967 began a unique record that shows the dramatic intensification of warming in the Hauraki Gulf......»»
Study shows inverting fusion plasmas improves performance
To become commercially viable, fusion power plants must create and sustain the plasma conditions necessary for fusion reactions. However, at high temperatures and densities, plasmas often develop gradients in those temperatures and densities. These g.....»»
