HTC Vive Pro's dual cameras can apparently track hand motion


When HTC unveiled its higher-end Vive Pro VR system back at CES, the company was suspiciously quiet about the dual cameras on this VR headset: there were no related demos, and the company reps remained tight-lipped. The smart-ass in me assumed that based on the similar looks, this module was probably a variant of the inside-out tracking sensor on the standalone Vive Focus, while others speculated that it would bring AR capability. Well, today we finally have an answer: it's actually a depth sensor, and it'll apparently enable basic hand tracking without additional hardware.

Specialized chaperones required


Although some proteins can reach a properly folded state without assistance, many require help to adopt the correct topology and avoid kinetic trapping in nonnative states. Chaperones encapsulate guest proteins and use adenosine triphosphate (ATP)–driven conformational changes to help them fold, but not all chaperones work for all substrates. Balchin et al. compared the folding pathway of the cytoskeleton protein actin with its proper chaperone, TRiC, to the incorrect folding that occurs with the bacterial chaperone GroEL. TRiC functions by stabilizing an extended form of actin with the proper secondary structure and topology. ATP binding and hydrolysis drives release of this partially folded intermediate into the chaperone where it can successfully fold.



HTC has unveiled Vivepaper, an app that lets Vive users check out interactive, VR content from publishers like Conde Nast. After you don the headset and scan a physical AR booklet, you can peruse a virtual magazine and load up 360-degree videos, 3D content, audio and other content. Vivepaper is launching in China with Conde Nast Traveler (China Edition), letting users play tourist with 360 degree video at locations around the world (see the video below). More publishers in the nation will release content soon, HTC says, and it's also "in discussions with several other major western publishers to release Vivepaper version of their content outside China shortly."

Mason cautions young models

FOX News

NEW YORK – Model Claudia Mason didn't have a guide to the glamorous and sometimes difficult life of modeling. So, she decided to write one: "Finding the Supermodel in You." For one, Mason says young models never go to castings or shoots without a chaperone. "My mother always insisted that there was a chaperone present if she couldn't - she was a single mother, working raising me – to go off and accompany me to Europe or certain jobs, or wherever that there was a chaperone," Mason told FOX411. "So, it is so important to have some adult figure."

[Review] In vivo aspects of protein folding and quality control


Over the past decade, we have gained substantial new insight into the overall behavior of the PN and the molecular mechanics of its components. Advances in structural biology and biophysical approaches have allowed chaperone mechanisms to be interrogated at an unprecedented level of detail. Recent work has provided fascinating insight into the process of protein folding on the ribosome and revealed how highly allosteric chaperones such as the heat shock protein 70 (Hsp70), Hsp90, and chaperonin systems modulate the folding energy landscapes of their protein clients. Studies of chaperone systems from bacteria and eukaryotes have revealed common principles underlying the organization of chaperone networks in different domains of life. Recently, we have begun to appreciate the relative complexity of eukaryotic chaperones and are starting to understand how eukaryotes deal with the challenge of folding a large proteome enriched in multidomain proteins.
