The newly-developed all-optical nanosensors are luminescent nanocrystals that can change intensity and/or color when you push or pull on them; they are probed with light only and therefore allow for fully remote read-outs — no wires or connections are needed; they have 100 times better force sensitivity than the existing nanoparticles that …
Parker Solar Probe Survives Closest-Ever Approach to Sun
Dec 30, 2024 · Close to the Sun, Parker Solar Probe relies on a carbon foam shield to protect it from the extreme heat in the upper solar atmosphere called the corona, which can exceed 500,000 degrees Celsius (1 million degrees Fahrenheit). The shield was designed to reach temperatures of 1,427 degrees Celsius (2,600 degrees Fahrenheit), while keeping the instruments behind it shaded at a comfortable room ...

Dec 17, 2024 · In a new paper, planetary researchers from Texas A&M University and the University of Washington introduce a new thermodynamic concept called the centotectic and investigate the stability of liquids in extreme conditions — critical information for determining the habitability of icy moons and ocean exoplanets.
545-Million-Year-Old Crater Could Reshape Our Understanding
Sep 24, 2024 · The Massive Australian Precambrian-Cambrian Impact Structure (MAPCIS) is a non-concentric complex crater about 600 km (370 miles) in diameter.. The impact occurred at the end of the Ediacaran period, approximately 545 million years ago. “The discovery of MAPCIS is a testament to the power of collaborative research,” said team member Dr. Daniel Connelly.
New Research Questions Standard Theory of How Galaxies
Nov 12, 2024 · The standard model predicted that the NASA/ESA/CSA James Webb Space Telescope would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped …
