Data-driven music: Converting climate measurements into music
A geo-environmental scientist from Japan has composed a string quartet using sonified climate data. The 6-minute-long composition—titled "String Quartet No. 1 "Polar Energy Budget"—is based on over 30 years of satellite-collected climate data fro.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
Cold Coulomb crystals, cosmic clues: Unraveling the mysteries of space chemistry
While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at l.....»»
Advanced nuclear magnetic resonance technique reveals precise structural, dynamical details in zeolites
Zeolites are widely used in many industries, yet their intrinsic catalytic nature is not completely understood, due to the complexity of the hydroxyl-aluminum moieties......»»
New book gives insider"s view of cosmic search for life
Whether life exists anywhere besides Earth is a burning question that, at long last, may soon be answered......»»
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much o.....»»
CMS collaboration releases Higgs boson discovery data to the public
As part of its continued commitment to making its science fully open, the CMS collaboration has just publicly released the combination of CMS measurements that contributed to establishing the discovery of the Higgs boson in 2012......»»
The Quest to Map the Inside of the Proton
Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces, and pressures inside a subatomic particle for the first time......»»
NASA"s PACE data on ocean, atmosphere, climate now available
NASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate......»»
Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments that have fundamental lim.....»»
Apple Vision Pro scans show meticulous array of cameras, sensors, and more
A new non-destructive teardown published today offers an incredible look inside Apple Vision Pro. Created using an industrial CT scanner, the images give us a look at the precise engineering that went into cramming all the cameras, sensors, and other.....»»
CMS experiment at CERN measures a key parameter of the Standard Model
Last week, at the annual Rencontres de Moriond conference, the CMS collaboration presented a measurement of the effective leptonic electroweak mixing angle. The result is the most precise measurement performed at a hadron collider to date and is in g.....»»
Solar eclipse chasers from Colorado will seek clues for predicting geomagnetic space storms
When Monday's solar eclipse casts its shadow, Colorado-based scientists will chase it in a jet flying faster than 500 mph and aim a coffin-shaped instrument straight at the sun's corona, taking measurements that eventually could help weather forecast.....»»
The universe"s accelerated expansion might be slowing down
The universe is still expanding at an accelerating rate, but it may have slowed down recently compared to a few billion years ago, early results from the most precise measurement of its evolution yet suggested Thursday......»»
DESI first-year data delivers unprecedented measurements of expanding universe
Scientists have analyzed the first batch of data from the Dark Energy Spectroscopic Instrument's quest to map the universe and unravel the mysteries of dark energy......»»
Turning microalgae into light-controlled, soft bio-microrobots
Micro/nanorobots, due to their small size, high controllability and precise navigation capabilities have emerged as an important tool to execute biomedical tasks in microenvironments. However, it is still a big challenge to maneuver rigid microrobots.....»»
Research team realizes magnonic frequency comb
The optical frequency comb, a spectrum of optical radiation composed of evenly spaced and phase-coherent narrow spectral lines, was initially developed for precise time and frequency measurements. Over the past two decades, it has shown broad applica.....»»
Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet
Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about 5 billion more years, bu.....»»
A cosmic "speed camera" just revealed the staggering speed of neutron star jets in a world first
How fast can a neutron star drive powerful jets into space? The answer, it turns out, is about one-third the speed of light, as our team has just revealed in a new study published in Nature......»»
