Observing the birth of a quasiparticle
Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances or entities in physical sys.....»»
Animals self-medicate with plants—a behavior people have observed and emulated for millennia
When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him......»»
Baby bonuses and wedding bells: How life"s big moments can challenge startups
Life-changing events like the birth of a child, the purchase of a new home, or a lottery win could threaten the survival of a new business venture, research from Edith Cowan University (ECU) has found. The work is published in the International Entre.....»»
Observing mammalian cells with superfast soft X-rays
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second......»»
Birth of universe"s earliest galaxies observed for first time
Using the James Webb Space Telescope, University of Copenhagen researchers have become the first to see the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important k.....»»
Stargazing in broad daylight: How a multi-lens telescope is changing astronomy
Astronomers at Macquarie University have pioneered a new technique for observing celestial objects during the day, potentially allowing around-the-clock visual monitoring of satellites and greatly improving safety on Earth and in space......»»
Expanding on the fundamental principles of liquid movement
From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces is a heavily researched sub.....»»
Saturday Citations: Mediterranean diet racks up more points; persistent quantum coherence; vegan dogs
This week, we reported on the birth throes of black holes, the questionable assertions of a study about vegan dogs and a technique for observing entanglement without breaking quantum coherence......»»
Monster galactic outflow powered by exploding stars
Star death and birth both contribute to driving material out of a galaxy. Enlarge / All galaxies have large amounts of gas that influence their star-formation rates. (credit: NASA, ESA, CSA, and J. Lee (NOIRLab)) Galaxie.....»»
How aging clocks tick: New study points to stochastic changes in cells
Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from chronological age that is calculated using the date of birth. The precis.....»»
Advanced experimental setup expands the hunt for hidden dark matter particles
Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like collisions, research.....»»
Two small NASA satellites will measure soil moisture, volcanic gases
Two NASA pathfinding missions were recently deployed into low-Earth orbit, where they are demonstrating novel technologies for observing atmospheric gases, measuring freshwater, and even detecting signs of potential volcanic eruptions......»»
International team detects eruption of mega-magnetic star in nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explos.....»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
Light show in living cells: New method allows simultaneous fluorescent labeling of many proteins
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually attached to each p.....»»
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......»»
Smart vest turns fish into underwater spies, providing a glimpse into aquatic life like never before
Traditional techniques for observing fish behavior, largely dependent on vision-based systems, face substantial limitations, such as a confined range of observation and a limited duration of operation underwater. In response to these challenges, a re.....»»
The sun was born when a dense gas cloud collapsed 4.6 billion years ago
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time......»»
Eclipses were once associated with the deaths of kings—predictions played a key role in the birth of astronomy
Making interesting predictions is one of the hallmarks of successful science. When Albert Einstein formulated his theory of general relativity, an almost immediate test involved the prediction that in a solar eclipse, light from stars that would norm.....»»
Student cleans up archival data and uncovers two stellar cocoons
While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds that had not been seen at this level of detail befor.....»»
Supercomputer simulations decode the mass puzzle of the first stars
Ching-Yao Tang and Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) have made substantial progress in decoding the birth mass of the first stars using the powerful supercomputer at Berkeley National Lab......»»
