Samples of Bennu were brought back to Earth by NASA’s OSIRIS-REx spacecraft in 2023. Now, a pair of newly published papers ...

Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission.

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission ...

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth ...

A recent study by researchers from Peking University demonstrates the potential of nuclear electric resonance to control the nuclear spins of nitrogen atoms in DNA using electric field gradients, ...

Chemical Engineering is concerned with the design and operation of processes which convert materials and energy into the higher value products we use every day. It understands the processes which ...

A computational study has replaced the carbon in cytosine, guanine, adenine, thymine and deoxyribose with nitrogen ... Piotr Skurski and Jakub Brzeski from the University of Gdańsk in Poland assessed ...

IN the nucleic acids, cytosine is connected to a sugar residue ... as is commonly found for purines and pyrimidines, but the structure is unusual in that the two bases do not lie in the same ...

which has thus become one of the most important means we have for investigating molecular structure. There is, indeed, no experimental method that gives more detailed information on this subject.

Beginning in the late 1970s, he effectively became a master builder in the nano universe — seeking how to use molecular bonds to fashion biological structures designed with a special purpose.
