Nonreciprocal interactions go nonlinear      (via sciencedaily.com)     Original source 

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

Dark matter flies ahead of normal matter in mega galaxy cluster collision      (via sciencedaily.com)     Original source 

Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.

Images of nearest 'super-Jupiter' open a new window to exoplanet research      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

3D-printed microstructure forest facilitates solar steam generator desalination      (via sciencedaily.com)     Original source 

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.

Expiring medications could pose challenge on long space missions      (via sciencedaily.com)     Original source 

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'      (via sciencedaily.com)     Original source 

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Life signs could survive near surfaces of Enceladus and Europa      (via sciencedaily.com)     Original source 

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

Early riser! The Sun is already starting its next solar cycle -- despite being halfway through its current one      (via sciencedaily.com)     Original source 

The first rumblings of the Sun's next 11-year solar cycle have been detected in sound waves inside our home star -- even though it is only halfway through its current one. This existing cycle is now at its peak, or 'solar maximum' -- which is when the Sun's magnetic field flips and its poles swap places -- until mid-2025.

New dawn for space storm alerts could help shield Earth's tech      (via sciencedaily.com)     Original source 

Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.

Come closer: Titanium-48's nuclear structure changes when observed at varying distances      (via sciencedaily.com)     Original source 

Researchers have found that titanium-48 changes from a shell model structure to an alpha-cluster structure depending on the distance from the center of the nucleus. The results upend the conventional understanding of nuclear structure and are expected to provide clues to the Gamow theory on the alpha-decay process that occurs in heavy nuclei, which has not been solved for nearly 100 years.

Exoplanet-hunting telescope to begin search for another Earth in 2026      (via sciencedaily.com)     Original source 

Europe's next big space mission -- a telescope that will hunt for Earth-like rocky planets outside of our solar system -- is on course to launch at the end of 2026. PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.

Physicists develop new theory describing the energy landscape formed when quantum particles gather together      (via sciencedaily.com)     Original source 

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.

Astronomers spot a 'highly eccentric' planet on its way to becoming a hot Jupiter      (via sciencedaily.com)     Original source 

The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.
