Scientists from The Ohio State University have a new theory about how the building blocks of life—the many proteins, carbohydrates, lipids and nucleic acids that compose every organism on Earth—may have evolved to favor a certain kind of molecular structure.
It has to do with a concept called chirality. A geometric property inherent to certain molecules, chirality can dictate a molecule’s shape, chemical reactivity, and how it interacts with other matter. Chirality is also sometimes referred to as handedness, as it can be best described as the dichotomy between our hands: Though they are not identical, the right and the left hand are mirror images of each other, and can’t be superimposed, or exactly overlaid on one another.
In the journal ACS Earth and Space Chemistry, researchers now propose a new model of how the molecules of life may have developed their “handedness.”

NASA’s NuSTAR telescope has spotted patches of high-energy X-rays radiation across the sun’s surface that could explain why the star’s atmosphere is mysteriously hot.
Spotting asteroids near the sun
Astronomers have gotten good at detecting even small asteroids that might be headed toward Earth. But an unknown number of asteroids have paths that might carry them toward us from the sun’s direction. And it’s tough – or impossible – to spot those asteroids coming toward us. ESA’s planned NEOMIR mission will orbit between Earth and the sun at the first Lagrange point (L1). It’ll act as an early warning system for asteroids – 65 feet (20 meters) and larger – that instruments on Earth’s surface cannot see.
NEOMIR stands for Near-Earth Object Mission in the Infrared.
AstroForge plans to mine asteroids, not for gold, but for platinum and other high-value metals. Will it succeed where others haven’t?
Using the ALMA telescope in Chile and Einstein’s theory of relativity, scientists observed a young galaxy in the early universe that is invisible in nearly every wavelength.
Scientists and government agencies have been worried about the space junk surrounding Earth for decades. But humanity’s starry ambitions are farther reaching than the space just around Earth.
A disruptive new planet-hunting technology, now under study as part of NASA’s Innovative Advanced Concepts (NIAC) program, could literally detect and then look for biosignatures from every Earth 2.0 within a thirty-light-year radius of our solar system.
Known as DICER (The Diffractive Interfero Coronagraph Exoplanet Resolver), the key to this NIAC study’s revolutionary means of detecting these planets is that unlike conventional optical space telescopes — which use curved, highly polished mirrors to collect starlight — this mission would employ flat sets of what are known as diffraction gratings.
Who says you need a conventional telescope to find exoplanets? NASA has funded a ‘Phase I’ study for the development of a whole new means of detecting and then teasing spectra from very nearby exoplanetary earths.
