New technique increases 3D printing speed by 1,000 to 10,000 times

Posted by in categories: 3D printing, biotech/medical, engineering, nanotechnology, robotics/AI

Any comments?

Ultraprecise 3D printing technology is a key enabler for manufacturing precision biomedical and photonic devices. However, the existing printing technology is limited by its low efficiency and high cost. Professor Shih-Chi Chen and his team from the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK), collaborated with the Lawrence Livermore National Laboratory to develop the Femtosecond Projection Two-photon Lithography (FP-TPL) printing technology.

By controlling the spectrum via temporal focusing, the laser 3D printing process is performed in a parallel layer-by-layer fashion instead of point-by-point writing. This new technique substantially increases the printing speed by 1,000—10,000 times, and reduces the cost by 98 percent. The achievement has recently been published in Science, affirming its technological breakthrough that leads nanoscale 3D printing into a new era.

New Tests Use Epigenetics to Guess How Fast You’re Aging

Posted by in categories: biotech/medical, genetics, life extension

From the beginning of time, humankind has searched for the secret to a long life. Now science may have found an answer, in the form of molecular augury. The pattern of chemical chains that attach to the DNA in your cells—on-off switches known as epigenetic markers—can reveal how swiftly you are aging, and perhaps even how much longer you will live. While genetic testing might tell you where you came from, epigenetics promises a glimpse into the future. Now, a handful of companies are offering commercial blood or saliva tests based on the science of epigenetics—a chance to find out how old you truly are.

Companies claim they can now easily calculate your biological age. Should you take them up on it?

IBM Research Created a New Battery That Outperforms Lithium-Ion—No Problematic Heavy Metals Required

Posted by in categories: materials, transportation

With everything from cars, to trucks, to even airplanes going electric, the demand for batteries is going to continue to skyrocket in the coming years—but the availability of the materials currently used to make them is limited. So scientists at IBM Research have developed a new battery whose unique ingredients can be extracted from seawater instead of mining.

Cops Can Now Get Warrants for Entire DNA Websites

Posted by in categories: biotech/medical, genetics, law enforcement, policy

To that end, Fields decided to ask a Florida judge to grant him a warrant that would override the new policy, allowing him to search GEDmatch’s entire database, including users who hadn’t opted in — and Judge Patricia Strowbridge did just that, the detective announced at a recent police convention, according to the NYT.

Legal experts told the NYT that this appears to be the first time a judge has approved a DNA website warrant this broad, with New York University law professor Erin Murphy calling it “a huge game-changer.”

“The company made a decision to keep law enforcement out, and that’s been overridden by a court,” Murphy told the newspaper. “It’s a signal that no genetic information can be safe.”
