Published How surface roughness influences the adhesion of soft materials



A research team discovers universal mechanism that leads to adhesion hysteresis in soft materials. Through a combination of experimental observations and simulations, the team demonstrated that roughness interferes with the separation process, causing the materials to detach in minute, abrupt movements, which release parts of the adhesive bond incrementally. The findings will make it possible to specifically control the adhesion properties of soft materials through surface roughness and will allow new and improved applications to be developed in soft robotics or production technology in the future.
Published Tiny wireless light bulbs for biomedical applications



The combination of OLEDs and acoustic antennas creates a light source that could be used for minimally invasive treatment methods.
Published CSI in space: Analyzing bloodstain patterns in microgravity



As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.
Published Interstellar signal linked to aliens was actually just a truck



Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published Baby quasars: Growing supermassive black holes



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 Researchers develop new machine learning method for modeling of chemical reactions



Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.
Published Finding new physics in debris from colliding neutron stars



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



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 Discovery tests theory on cooling of white dwarf stars



Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published Key advance toward removing common herbicide from groundwater



Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.
Published Aluminum nanoparticles make tunable green catalysts



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 Harmful 'forever chemicals' removed from water with new electrocatalysis method



Scientists have developed new electrochemical approaches to clean up pollution from 'forever chemicals' found in clothing, food packaging, firefighting foams, and a wide array of other products. A new study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances, known as PFAS.
Published Using light to precisely control single-molecule devices



Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms



Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Space tourism? Cosmic radiation exposure



Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars



A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery



It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa



NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published JWST captures the end of planet formation



The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.
Published Webb unlocks secrets of one of the most distant galaxies ever seen



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.
