3D printed tires and shoes that self-repair

Posted by in categories: 3D printing, chemistry, life extension, robotics/AI

Instead of throwing away your broken boots or cracked toys, why not let them fix themselves? Researchers at the University of Southern California Viterbi School of Engineering have developed 3D-printed rubber materials that can do just that.

Assistant Professor Qiming Wang works in the world of 3D printed materials, creating new functions for a variety of purposes, from flexible electronics to sound control. Now, working with Viterbi students Kunhao Yu, An Xin, and Haixu Du, and University of Connecticut Assistant Professor Ying Li, they have made a new material that can be manufactured quickly and is able to repair itself if it becomes fractured or punctured. This material could be game-changing for industries like shoes, tires, soft robotics, and even electronics, decreasing manufacturing time while increasing product durability and longevity.

New ‘acoustic metamaterial’ cancels sound

Posted by in category: engineering

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

Reversing Cognitive Decline

Posted by in categories: life extension, neuroscience

A team of Stanford researchers led by Professor Wyss-Coray set out to find out which genes were linked to age-related cognitive decline. Not only did the researchers find the culprit, they were able to reverse cognitive decline and rejuvenate aged mouse brains.

Searching for the cause of cognitive decline

Microglia are immune cells that reside in the brain and spinal cord. These cells mediate immune responses in the central nervous system and act like other macrophages, clearing cellular debris and dead neurons from nervous tissue through the process of phagocytosis (cell eating).

Blue Origin urging Air Force to postpone launch competition

Posted by in categories: military, satellites

COLORADO SPRINGS — Blue Origin wants the U.S. Air Force to wait until 2021 before picking the two companies it intends use for launching critical military satellites in the decade ahead.

The Air Force, however, aims to solicit proposals this spring and choose its two preferred launch providers in 2020 — perhaps a year or more before the new rockets that the Air Force is fostering at Blue Origin, United Launch Alliance and Northrop Grumman make their first flights.

All three companies were chosen in October by the Air Force Space and Missile Systems Center to share $2.3 billion in so-called Launch Service Agreement (LSA) funding to support development of next-generation rockets capable of meeting the military’s satellite launch needs.
