Boeing unveils refreshed jet concept with ultra-thin wings

SAN DIEGO (Reuters) — Boeing Co unveiled a speedier and higher-flying version of a concept plane on Tuesday aimed at sharply reducing fuel use thanks to its elongated ultra-light wings.

The so-called Transonic Truss-Braced Wing aircraft boasts a 170-foot (52 meter) wingspan that sits atop the fuselage and is braced from underneath by a truss in a design reminiscent of biplanes from the early years of aviation.

The world’s largest planemaker and U.S. space agency NASA have been studying the concept plane for nearly a decade as part of the Subsonic Ultra Green Aircraft Research program. Boeing unveiled a reconfigured model or prototype and artist’s rendering at an aerospace conference in San Diego.

Researchers Reveal Inner Workings of the Proteasome

Researchers from Scripps Research have discovered how the proteasome, which is made of protein complexes in the cell that breaks down damaged and unwanted proteins, converts energy into motion to unfold target proteins for recycling.

What is the proteasome?

The proteasome is a protein complex whose job is to break down and recycle proteins that have become damaged or are no longer required. It achieves this via a process called proteolysis, a chemical reaction that breaks the peptide bonds, thus allowing the target protein to be destroyed and broken down into its constituent parts, which become ready to be reused to make new proteins. The enzymes that facilitate this recycling process are known as proteases.
