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 Tiny wireless light bulbs for biomedical applications
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Nanodevices can produce energy from evaporating tap or seawater
(via sciencedaily.com) Original source Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.
Published Healable cathode could unlock potential of solid-state lithium-sulfur batteries
(via sciencedaily.com) Original source Engineers developed a cathode material for lithium-sulfur (Li-S) batteries that is healable and highly conductive, overcoming longstanding challenges of traditional sulfur cathodes. The advance holds promise for bringing more energy dense and low-cost Li-S batteries closer to market.
Published Space tourism? Cosmic radiation exposure
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Juno spacecraft measures oxygen production on Jupiter's moon, Europa
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Scientists put forth a smarter way to protect a smarter grid
(via sciencedaily.com) Original source Scientists have put forth a new approach to protect the electric grid, creating a tool that sorts and prioritizes cyber threats on the fly.
Published Study determines the original orientations of rocks drilled on Mars
(via sciencedaily.com) Original source Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published Unlocking the potential of lithium-ion batteries with advanced binders
(via sciencedaily.com) Original source Lithium-ion batteries employ binders that encounter challenges such as poor conductivity and expansion during charging. In a recent study, scientists have developed a high-performing binder using poly(vinylphosphonic acid) for silicon oxide-based anodes in lithium-ion batteries. This binder offers enhanced performance as demonstrated by the superior durability, and discharging capacity of the anodes compared to conventional options. With patents filed internationally, this technology holds promise for broader applications in electric vehicles and beyond.
Published Lithium-ion batteries from drones might find second lives in less 'stressful' devices
(via sciencedaily.com) Original source Taking flight can be stressful -- especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device's overall lifespan. Research shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the 'stressed out' batteries could also have second lives in less strenuous applications.
Published Ultraviolet radiation from massive stars shapes planetary systems
(via sciencedaily.com) Original source Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Hurricanes and power grids: Eliminating large-scale outages with a new approach
(via sciencedaily.com) Original source Large scale-power outages caused by tropical cyclones can be prevented almost entirely if a small but critical set of power lines is protected against storm damages, a new study finds. Scientists developed a new method that can be used to identify those critical lines and increase the system's resilience.
Published Ice shell thickness reveals water temperature on ocean worlds
(via sciencedaily.com) Original source Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Published Improving energy security with policies focused on demand-side solutions
(via sciencedaily.com) Original source Energy systems essential to supporting our everyday activities face increasing threats from wars, pandemics, climate change, and other unexpected events. An international team of researchers found that demand-oriented solutions have a significantly greater potential to reduce our vulnerability to energy crises compared to supply measures.
Published Could fiber optic cable help scientists probe the deep layers of the moon?
(via sciencedaily.com) Original source An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth -- but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space?
Published Biomolecules from formaldehyde on ancient Mars
(via sciencedaily.com) Original source Organic materials discovered on Mars may have originated from atmospheric formaldehyde, according to new research, marking a step forward in our understanding of the possibility of past life on the Red Planet.
