Published Giving particle detectors a boost
(via sciencedaily.com) Original source Researchers have tested the performance of a new device that boosts particle signals.
Published GPS nanoparticle platform precisely delivers therapeutic payload to cancer cells
(via sciencedaily.com) Original source A newly developed 'GPS nanoparticle' injected intravenously can home in on cancer cells to deliver a genetic punch to the protein implicated in tumor growth and spread, according to researchers. They tested their approach in human cell lines and in mice to effectively knock down a cancer-causing gene, reporting that the technique may potentially offer a more precise and effective treatment for notoriously hard-to-treat basal-like breast cancers.
Published Peering into the tendrils of NGC 604 with NASA's Webb
(via sciencedaily.com) Original source The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Breakthrough in nanostructure technology for real-time color display
(via sciencedaily.com) Original source New groundbreaking technology enables the real-time display of colors and shapes through changes in nanostructures.
Published Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists
(via sciencedaily.com) Original source When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com) Original source Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published Pushing the boundary on ultralow frequency gravitational waves
(via sciencedaily.com) Original source A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe.
Published Baby quasars: Growing supermassive black holes
(via sciencedaily.com) Original source The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.
Published Finding new physics in debris from colliding neutron stars
(via sciencedaily.com) Original source Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed
(via sciencedaily.com) Original source A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published New type of nanoparticle makes vaccines more powerful
(via sciencedaily.com) Original source A type of nanoparticle called a metal organic framework (MOF) could be used to deliver vaccines and act as an adjuvant. Researchers find these particles provoke a strong immune response by activating the innate immune system through cell proteins called toll-like receptors.
Published Aluminum nanoparticles make tunable green catalysts
(via sciencedaily.com) Original source A nanotechnology pioneer has uncovered a transformative approach to harnessing the catalytic power of aluminum nanoparticles by annealing them in various gas atmospheres at high temperatures.
Published Using light to precisely control single-molecule devices
(via sciencedaily.com) Original source Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published Researchers closing in on genetic treatments for hereditary lung disease, vision loss
(via sciencedaily.com) Original source Researchers who work with tiny drug carriers known as lipid nanoparticles have developed a new type of material capable of reaching the lungs and the eyes, an important step toward genetic therapy for hereditary conditions like cystic fibrosis and inherited vision loss.
Published 'Like a lab in your pocket' -- new test strips raise game in gene-based diagnostics
(via sciencedaily.com) Original source Biosensing technology developed by engineers has made it possible to create gene test strips that rival conventional lab-based tests in quality.
Published Webb unlocks secrets of one of the most distant galaxies ever seen
(via sciencedaily.com) Original source Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published Spontaneous curvature the key to shape-shifting nanomaterials
(via sciencedaily.com) Original source Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
Published New insights on how galaxies are formed
(via sciencedaily.com) Original source Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these.
Published Scientists make nanoparticles dance to unravel quantum limits
(via sciencedaily.com) Original source The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published Umbrella for atoms: The first protective layer for 2D quantum materials
(via sciencedaily.com) Original source As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.
