A new way to look for gravitational waves
In a paper published today in Physical Review Letters, Valerie Domcke of CERN and Camilo Garcia-Cely of DESY report on a new technique to search for gravitational waves—the ripples in the fabric of spacetime that were first detected by the LIGO and.....»»
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......»»
"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.....»»
Astrophysicist"s research could provide a hint in the search for dark matter
Dark matter is one of science's greatest mysteries. It doesn't absorb, reflect or emit light, so we can't see it. But its presence is implied by the gravitational effects it appears to have on galaxies......»»
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......»»
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.....»»
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......»»
New type of tunable filter reveals the potential for terahertz wireless communications
Electromagnetic waves in the terahertz frequency range offer many advantages for communications and advanced applications in scanning and imaging, but realizing their potential poses challenges. Researchers at Tohoku University have addressed one of.....»»
Global warming may be behind an increase in the frequency and intensity of cold spells
Global warming caused by increased concentrations of greenhouse gases is already affecting our lives. Scorching summers, more intense heat waves, longer drought periods, more extended floods, and wilder wildfires are consequences linked to this warmi.....»»
Maximizing Security and Efficiency in Your Business with Linux
In the bustling digital marketplace of today, businesses are like ships navigating through a sea of data, facing storms of cyber threats and waves of technological challenges. At the heart of these vessels, ensuring a smooth and secure voyage, lies t.....»»
Radio waves can tune up bacteria to become life-saving medicines
Scientists from Australia and the United States have found a new way to alter the DNA of bacterial cells—a process used to make many vital medicines including insulin—much more efficiently than standard industry techniques......»»
How "the strong force" influences the gravitational wave background
Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe......»»
Could fiber optic cable help scientists probe the deep layers of the moon?
An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the moon, and what would it tell us about the deep layers of our nearest neighbor in space?.....»»
Nature"s sonar: Scientists reveal how Japanese horseshoe bats perceive moving objects
Unlike most animals that rely on visual senses, bats navigate and locate prey or obstacles through echolocation. By emitting sounds and comparing them to the reflected echoes, bats can "visualize" movement in the environment. When sound waves encount.....»»
African great apes predicted to see frequent extreme climate events in the next 30 years
African apes are already being exposed to climate change impacts, and will experience extreme events such as wildfires, heat waves and flooding more frequently in the next 30 years, according to a study published February 28 in the open-access journa.....»»
Humanity Is Dangerously Pushing Its Ability to Tolerate Heat
Extreme heat waves are already here, and they are killing tens of thousands of people. Blasting through 2 degrees Celsius of warming means they’ll happen many times more frequently......»»
