magnetic-wormhole ft

A wormhole* that can connect two regions of space magnetically has been created in the laboratory and experimentally demonstrated by physicists at Universitat Autònoma de Barcelona in Spain.

This is not a wormhole in space, as in the movie Interstellar. It’s a special design that transfers a magnetic field from one location in space to another in such a way that the process is magnetically… read more

New laser design could dramatically shrink autonomous-vehicle 3-D laser-ranging systems

September 4, 2015

This self-sweeping laser couples an optical field with the mechanical motion of a high-contrast grating (HCG) mirror. The HCG mirror is supported by mechanical springs connected to layers of semiconductor material. The red layer represents the laser’s gain (for light amplification), and the blue layers form the system’s second mirror. The force of the light causes the top mirror to vibrate at high speed. The vibration allows the laser to automatically change color as it scans. (credit: Weijian Yang)

UC Berkeley engineers have invented a new laser-ranging system that can reduce the power consumption, size, weight and cost of LIDAR (light detection and ranging, aka “light radar”), which is used in self-driving vehicles* to determine the distance to an object, and in real-time image capture for 3D videos.

“The advance could shrink components that now take up the space of a shoebox down to… read more

A user-friendly 3-D printing interface for customizing designs

Design tool lets novices do in minutes what would take experts in computer-aided design hours
September 4, 2015

A new Web-based interface for design novices allows a wide range of modifications to a basic design — such as a toy car or a black-and-white "yin-yang" cup — that are guaranteed to be both structurally stable and printable on a 3-D printer. (credit: Courtesy of the researchers (edited by MIT News))

Researchers at MIT and the Interdisciplinary Center Herzliya in Israel have developed a system that automatically turns CAD files into visual models that users can modify in real time, simply by moving virtual sliders on a Web page. Once the design meets their specifications, they can hit the print button to send it to a 3-D printer.

Currently, 3-D printing an object from any but the simplest designs requires… read more

A novel porous material that achieves carbon dioxide (CO2) capture-and-release with only small shifts in temperature has been developed by a team of researchers at the Center for Gas Separations Relevant to Clean Energy Technologies, led by the University of California, Berkeley (a DOE Energy Frontier Research Center), and associates.

This metal-organic framework (MOF) structure, which adsorbs* CO2, closely resembles an… read more

Tufts University scientists have developed a silk-based bio-ink that could allow for printing tissues that could be loaded with pharmaceuticals, cytokines (for directing stem cell functions), and antibiotics (for controlling infections), for example, or used in biomedical implants and tissue engineering.

Current 3-D printing processes are limited to simple body parts such as bone. And most inks currently being developed for 3-D printing are made of thermoplastics, silicones, collagen,… read more

Completely paralyzed man voluntarily moves his legs, UCLA scientists report

In 1998, athlete Mark Pollock became the first blind man to race to the South Pole; now "Iron ElectriRx" man is making history again --- in a robotic exoskeleton

The good news: as for 2013, global life expectancy for people in 188 countries has risen 6.2 years since 1990 (65.3 to 71.5). The bad news: healthy life expectancy (HALE) at birth rose by only 5.4 years (56.9 to 62.3), due to fatal and nonfatal ailments (interactive visualization by country here).

In other words, people are living more years with illness and disability. Ischemic heart disease, lower… read more
