Undergrad publishes theory on immune dysfunction in space

It's been known for decades that though astronauts' immune systems become suppressed in space, leaving them vulnerable to disease, the exact mechanisms of immune dysfunction have remained a mystery. Now a Cornell undergraduate has found a potential solution.
A biological and mechanical engineering double major in the College of Engineering, Rocky An published his theory, "MRTF May be the Missing Link in a Multiscale Mechanobiology Approach toward Macrophage Dysfunction in Space," Sept. 12 in Frontiers in Cell and Developmental Biology.
An reviewed the last 20 years of literature on the behavior of macrophages—key cells in the body's immune response—in space and recent research about how macrophages respond to forces in normal gravity, identifying a transcription factor that could prove to be the missing piece of the puzzle.
"I just kept asking questions about how the data is presented," An said. "There are these two really important papers, in particular, one a review of how macrophages are suppressed in microgravity, and another about the mechanobiology of macrophages.
Lynk Global gets first commercial satellite direct-to-cell operating license

New exoplanet detection program for citizen scientists
Monday, 19 September 2022 15:51 Write a comment
The SETI Institute and its partner Unistellar are launching a new exoplanet detection program that will engage citizen scientists worldwide. Amateur astronomers, using either Unistellar's eVscope or another telescope, will be invited to help confirm exoplanet candidates identified by NASA's Transiting Exoplanet Survey Satellite (TESS) by observing possible exoplanet transits from Earth.
Most known exoplanets have been detected using the transit method, most notably by the Kepler Mission and now TESS. A transit is when a planet passes between its star and the observer, who will see the star dimming as the planet orbits. The demand for follow-up observations of transiting exoplanets is greater than ever. There are currently more than 5,100 confirmed exoplanets, with thousands more detections to be confirmed. This program will focus its efforts on exo-Jupiters detected by those NASA missions.
Some estimates suggest that TESS will identify more than 10,000 exoplanet candidates.
Ariane 5: payload and geography open super-efficient path to GEO

Satellite mission confirms cornerstone of general relativity is unshakeable
Monday, 19 September 2022 10:40 Write a comment
The MICROSCOPE mission has confirmed the 'equivalence principle' with unprecedented accuracy, bolstering Einstein's general relativity.
The result, announced this week by a team led by the French space agency CNES, is a triumph for Einstein's general relativity. However, it also potentially rules out some candidate universal theories of physics.
