Uncorking champagne bottle produces supersonic shock waves
Opening a bottle of champagne traditionally marks the beginning of a festive celebration. Following the fun pop of the cork, a fizz of bubbles releases into the air, and finally, there is the pleasant tingle on the tongue......»»
Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
Shear waves split into fast and slow waves when they travel through elastically anisotropic media, and the anisotropy of the seismic velocity is recorded by seismic stations. In the Earth's deep interior, this is usually interpreted as the effect of.....»»
Internet fiber optic cables successfully detect shock waves from a rockslide
On the night of 16 June 2023, about 1.2 million cubic meters of rock rumbled down into the valley near Brienz (GR). A team from the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and ETH Zurich tracked the event using an unusual.....»»
NASA reveals prototype telescope for gravitational wave observatory
NASA has revealed the first look at a full-scale prototype for six telescopes that will enable, in the next decade, the space-based detection of gravitational waves—ripples in space-time caused by merging black holes and other cosmic sources......»»
A blueprint for mapping melting ice sheets: Open-source tool can help make radar systems at a fraction of the cost
Researchers in the Stanford Radio Glaciology lab use radio waves to understand rapidly changing ice sheets and their contributions to global sea-level rise. This technique has revealed groundwater beneath Greenland, the long-term impacts of extreme m.....»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»
Ocean eddy currents funnel extreme heat and cold to the life-filled depths
On land, we're familiar with heat waves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold......»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
First results from the Axion Dark-Matter Birefringent Cavity experiment establish a new technique for axion search
Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical Review Letters, did not.....»»

Hurricane Helene Damage Strains Dialysis Care Nationwide
Hurricane Helene devastated a North Carolina facility that produces peritoneal dialysis fluid, which is used by about 80,000 people nationally.....»»
Global temperature analysis reveals deep ocean marine heat waves are underreported
While marine heat waves (MHWs) have been studied at the sea surface for more than a decade, new research published today in Nature has found 80% of MHWs below 100 meters are independent of surface events, highlighting a previously overlooked aspect o.....»»
Dutch students warn space mission of noisy white dwarfs
The background noise of gravitational waves from orbiting white dwarf stars will be stronger than the noise from binary black holes. This is what two Dutch master's students and their supervisor predict in two papers in anticipation of the LISA space.....»»
In a fusion device plasma, a steep ion temperature gradient slows the growth of magnetic islands
Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to "bottle" plasma. However, magnetic.....»»
Spin-wave reservoir chips can enhance edge computing
Reservoir computing (RC) has a few benefits over other artificial neural networks, including the reservoir that gives this technique its name. The reservoir functions mainly to nonlinearly transform input data more quickly and efficiently. Spin waves.....»»
Global warming is happening, but not statistically "surging," new study finds
Given the number of record-setting heat waves around the world in recent years, an international team of researchers, including a Lancaster University statistician, investigated if the rate of global warming has increased significantly, or "surged,".....»»
Researchers develop a laser that produces the strongest ultra-short laser pulses to date
The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry often also require very short and strong pulses of la.....»»
Researchers uncover role of plasma waves in mysterious heating of sun"s corona
There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter......»»
What yields per acre reveal about the impact of extreme weather
Since time immemorial, crop yields have been influenced by such extreme weather phenomena as heat waves, persisting droughts, downpours and lasting rainfall. Many studies have already demonstrated that due to climate change, periods of extreme weathe.....»»
Huge waves in the atmosphere dump extreme rain on northern Australia
In 2023, almost a year's worth of rain fell over ten days in parts of northwestern Australia, leading to catastrophic flooding in the town of Fitzroy Crossing and surrounds. The rainfall was linked to a tropical cyclone, but there were also lesser-kn.....»»
Google identifies low noise “phase transition” in its quantum processor
Benchmark may help us understand how quantum computers can operate with low error. Back in 2019, Google made waves by claiming it had achieved what has been called "quantum suprem.....»»
