Quasars as the new cosmic standard candles

In 1929, Edwin Hubble published observations that galaxies' distances and velocities are correlated, with the distances determined using their Cepheid stars. Harvard astronomer Henrietta Swan Leavitt had discovered that a ...

Catalyst study advances carbon-dioxide-to-ethanol conversion

An international collaboration of scientists has taken a significant step toward the realization of a nearly "green" zero-net-carbon technology that will efficiently convert carbon dioxide, a major greenhouse gas, and hydrogen ...

Using electricity to give chemistry a boost

Metal organic frameworks (MOFs) are a promising class of materials that have many applications as catalysts, sensors and for gas storage. Widely studied over the past two decades, MOFs are typically produced using chemical ...

Natural killer cells coordinate wound healing

Natural killer cells do not just kill cancer cells or cells infected with viruses, they also mediate a trade-off between wound healing and bacterial defense in skin wounds. If the healing process is accelerated, the immune ...
