Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial shows extraordinary promise as a shield for human tissue against harmful radiation.
It lacks the drama of a shape-shifting alien creature, but another threat looms over the prospect of generations-long, interstellar space travel: Explorers arriving on Xanadu could face problems communicating with previous and subsequent arrivals, their spoken language having changed in isolation along the way. A new paper looks at the issues.
Analysis of seismometer data from the InSight Martian lander revealed that different types and frequencies of ambient low-magnitude "microtremors" on Mars were associated with different sources, and some reflected daily variations in wind and solar irradiance, either in distant locations or near the lander. These findings will contribute to future projects seeking to model and monitor the Martian subsurface.
The Moon's subsurface might be richer in metals, like iron and titanium, than researchers thought.
On a quest to find the Universe's largest black holes, Vanderbilt researcher identifies the center of the solar system within 100 meters.
Southwest Research Institute scientists have increased the speed and accuracy of a laboratory-scale instrument for determining the age of planetary specimens onsite. The team is progressively miniaturizing the Chemistry, Organics and Dating Experiment (CODEX) instrument to reach a size suitable for spaceflight and lander missions.
A Clemson University scientist has joined forces with an international team of astronomers to identify periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their centers.
Funding helps develop cutting edge space capabilities in Australia and collaboration with multiple Australian space industry companies and the Italian Space Agency
There may be as many as one Earth-like planet for every five Sun-like stars in the Milky way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASA's Kepler mission.
The collaborative research team of Japan using the International Space Station (ISS) successfully characterized Alzheimer's disease-related amyloid fibril formation under microgravity conditions. Their findings demonstrated that amyloid fibril formation on the ISS is significantly slower than that on the Earth. Moreover, microgravity promoted the formation of distinct morphologies of amyloid fibrils. The project highlights the utility of the ISS as an ideal experimental environment for investigating amyloid formation mechanisms without uncontrollable perturbations caused by gravity.
