Now you can ‘build your own’ bio-bot

Public Release: 13-Feb-2017   University of Illinois College of Engineering   Caption This is a schematic of a bio-bot: Engineered skeletal muscle tissue is coupled to a 3-D printed flexible skeleton. Optical stimulation of the muscle tissue, which is genetically engineered to contract in response to blue light, […]

Your body may soon be inhabited by swarms of microrobots

The microdoctors in our bodies Date: September 21, 2016 Source: ETH Zurich Summary: Researchers are developing tiny, sophisticated technological and biological machines enabling non-invasive, selective therapies. Their creations include genetically modified cells that can be activated via brain waves, and swarms of microrobots that facilitate highly precise application […]

How to erase a memory — and restore it

  Researchers at the University of California, San Diego School of Medicine have erased and reactivated memories in rats, profoundly altering the animals’ reaction to past events.   The study, published in the June 1 advanced online issue of the journal Nature, is the first to show the […]

Blueprint for an artificial brain

Published 26. February 2013, 15:18 h     Bielefeld physicist Andy Thomas takes nature as his model   Scientists have long been dreaming about building a computer that would work like a brain. This is because a brain is far more energy-saving than a computer, it can learn […]

Walking again after spinal injury ( sprinting, climbing up stairs, and avoiding obstacles after a couple of weeks of neurorehabilitation )

Contact: Hillary Sanctuary hillary.sanctuary@epfl.ch 41-797-034-809 Ecole Polytechnique Fédérale de Lausanne In the lab, rats with severe spinal cord injury are learning to walk—and run—again. Last June in the journal Science, Grégoire Courtine, of the École Polytechnique Fédérale de Lausanne (EPFL), reported that rats in his lab are not […]

Cartilage made easy with novel hybrid printer

Contact: Michael Bishop michael.bishop@iop.org 01-179-301-032 Institute of Physics The printing of three-dimensional tissue has taken a major step forward with the creation of a novel hybrid printer that simplifies the process of creating implantable cartilage. The printer has been presented today, 22 November, in IOP Publishing’s journal Biofabrication, […]

Brain-like chip outstrips normal computers

22 November 2012 by Michael Marshall Magazine issue 2892. COMPUTER chips that mimic the human brain are outstripping conventional chips in crucial ways. They could also revolutionise our understanding of how the brain functions.Attempts to simulate the brain usually involve programming software to behave like groups of neurons. […]

These Mini-Bots Were Made for Walking: Cells Power Biological Machines: non-electronic biological machines

Miniature “bio-bots” developed at the University of Illinois are made of hydrogel and heart cells, but can walk on their own. (Credit: Elise A. Corbin) ScienceDaily (Nov. 15, 2012) — They’re soft, biocompatible, about 7 millimeters long — and, incredibly, able to walk by themselves. Miniature “bio-bots” developed […]

Activating the ‘mind’s eye’ — sounds, instead of eyesight can be alternative vision ( can actually “see” and describe objects and even identify letters and words )

Contact: Jerry Barach jerryb@savion.huji.ac.il 972-258-82904 The Hebrew University of Jerusalem Jerusalem, Nov. 7, 2012 — Common wisdom has it that if the visual cortex in the brain is deprived of visual information in early infanthood, it may never develop properly its functional specialization, making sight restoration later in […]

Hacking the President’s DNA : Personalized Bioweapons

The U.S. government is surreptitiously collecting the DNA of world leaders, and is reportedly protecting that of Barack Obama. Decoded, these genetic blueprints could provide compromising information. In the not-too-distant future, they may provide something more as well—the basis for the creation of personalized bioweapons that could take […]

Brain waves reveal video game aptitude
