Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards      (via sciencedaily.com)     Original source 

Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

Scientists map gusty winds in a far-off neutron star system      (via sciencedaily.com)     Original source 

Astronomers have mapped the 'disk winds' associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star. The findings may offer clues to how supermassive black holes shape entire galaxies.

This elephant's self-taught banana peeling offers glimpse of elephants' broader abilities      (via sciencedaily.com)     Original source 

Elephants like to eat bananas, but they don't usually peel them first in the way humans do. A new report however, shows that one very special Asian elephant named Pang Pha picked up banana peeling all on her own while living at the Berlin Zoo. She reserves it for yellow-brown bananas, first breaking the banana before shaking out and collecting the pulp, leaving the thick peel behind.

Webb reveals never-before-seen details in Cassiopeia A      (via sciencedaily.com)     Original source 

The explosion of a star is a dramatic event, but the remains the star leaves behind can be even more dramatic. A new mid-infrared image from NASA's James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion seen from Earth 340 years ago. Cas A is the youngest known remnant from an exploding, massive star in our galaxy, which makes it a unique opportunity to learn more about how such supernovae occur.

How to see the invisible: Using the dark matter distribution to test our cosmological model      (via sciencedaily.com)     Original source 

Astrophysicists have measured a value for the 'clumpiness' of the universe's dark matter (known to cosmologists as 'S8') of 0.776, which does not align with the value derived from the Cosmic Microwave Background, which dates back to the universe's origins. This has intriguing implications for the standard cosmological model.

Spike in major league home runs tied to climate change      (via sciencedaily.com)     Original source 

A new study identifies the influence of climate change in the greater number of home runs in major league baseball in recent years. The researchers found that more than 500 home runs since 2010 can be attributed to warmer, thinner air caused by global warming, and that rising temperatures could account for 10% or more of home runs by 2100 if greenhouse gas emissions continue unabated. The researchers examined how the average number of home runs per year could rise for each major league ballpark with every 1-degree Celsius increase in the global average temperature.

NASA's Webb scores another ringed world with new image of Uranus      (via sciencedaily.com)     Original source 

Following in the footsteps of the Neptune image released in 2022, NASA's James Webb Space Telescope has taken a stunning image of the solar system's other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet's atmosphere. The Webb data demonstrates the observatory's unprecedented sensitivity for the faintest dusty rings, which have only ever been imaged by two other facilities: the Voyager 2 spacecraft as it flew past the planet in 1986, and the Keck Observatory with advanced adaptive optics.

Technology advance paves way to more realistic 3D holograms for virtual reality and more      (via sciencedaily.com)     Original source 

Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.

Hubble sees possible runaway black hole creating a trail of stars      (via sciencedaily.com)     Original source 

There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.

Researchers create embryo-like structures from monkey embryonic stem cells      (via sciencedaily.com)     Original source 

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. Investigators now report on the creation of embryo-like structures from monkey embryonic stem cells. The investigators also transferred these embryo-like structures into the uteruses of female monkeys and determined that the structures were able to implant and elicit a hormonal response similar to pregnancy.

Super-sized nanocage could deliver bigger drug cargoes      (via sciencedaily.com)     Original source 

Nanocages are tiny artificial containers that can be used to deliver therapeutics to a target destination in the body. But some drug molecules are like gifts that are too big for a standard-sized nanocage 'box'. Now researchers describe how they have built a super-sized nanocage that could be used to deliver larger drug cargoes. They have built a bigger box.

Twinkling stars fuel interstellar dust      (via sciencedaily.com)     Original source 

Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust. Dusty AGBs are particularly prominent producers of dust, and the light they shine happens to vary widely. For the first time, a long-period survey has found the variable intensity of dusty AGBs coincides with variations in the amount of dust these stars produce. As this dust can lead to the creation of planets, its study can shed light on our own origins.

Hubble unexpectedly finds double quasar in distant universe      (via sciencedaily.com)     Original source 

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based observatories, astronomers investigating these developments have made an unexpected and rare discovery: a pair of gravitationally bound quasars, both blazing away inside two merging galaxies. They existed when the universe was just 3 billion years old.

How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?      (via sciencedaily.com)     Original source 

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on the giant precursors of asteroids like Ryugu. Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas and dust orbiting it. The dusty material collided to produce rocky material that would eventually grow in size to give large bodies called planetesimals.

Absolute zero in the quantum computer      (via sciencedaily.com)     Original source 

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.
