CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day.

The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy.

While the quasar resembles a mere dot in images, scientists envision a ferocious place.

This is all good but I really like the telomeres results.

To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process. Their work has now been published in Angewandte Chemie International Edition.

Polypropionates are natural products that can help save lives. They are needed to make reserve antibiotics, compounds that are only ever used to treat infections caused by drug-resistant bacteria. In nature, chiral compounds exist in two different variants that share the same molecular formula but are mirror images of each other, like a right and a left hand. Chemists call this “chirality,” which literally means “handedness.”

“What’s interesting is that the mirror-image forms can have very different properties,” explains Professor Andreas Gansäuer from the Kekulé Institute of Organic Chemistry and Biochemistry at the University of Bonn. “One well known example is undoubtedly carvone. The dextro-, or ‘right-handed,’ form of this molecule smells of caraway, while its levo-, or ‘left-handed,’ form is what gives peppermint its distinctive odor.”

Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. The technology is called Twistact, and it will eliminate the need for expensive rare-earth magnets in large wind turbines.

Sandia is now ready to partner with the energy industry to develop the next generation of direct-drive wind turbines.

Sandia’s Twistact is a novel approach to transmitting electrical current between a stationary and rotating frame, or between two rotating assemblies having different speeds or rotational directions. This method is ideal for use in wind turbines.
