Nanorobots target cancerous tumors with precision


Researchers from Polytechnique Montréal, Université de Montréal and McGill University have just achieved a spectacular breakthrough in cancer research. They have developed new nanorobotic agents capable of navigating through the bloodstream to administer a drug with precision by specifically targeting the active cancerous cells of tumours. This way of injecting medication ensures the optimal targeting of a tumour and avoids jeopardizing the integrity of organs and surrounding healthy tissues. As a result, the drug dosage that is highly toxic for the human organism could be significantly reduced.

‘Neural Dust’ Could Monitor Your Brain Wirelessly


Science fiction that features wires connecting brains to computers might now be obsolete. Wireless powered implants, each smaller than a grain of rice, could serve as “neural dust” that can one day scan and stimulate brain cells. Such research could one day help lead to next-generation brain-machine interfaces for controlling prosthetics, exoskeletons and robots, as well as “electroceuticals” to treat disorders of the brain and body.

Can an electronic face ‘tattoo’ biometrically map your mood swings?


Here’s a tattoo your mom might actually condone you getting.

The temporary, electronic “tattoo,” developed by a team of scientists at Tel Aviv University’s Center for Nanoscience and Nanotechnology, sticks to skin and uses a carbon electrode and a conductive polymer to measure biometric signals for hours. When worn on the face, the electrodes are sensitive enough to record variations in muscle activity, which can identify expressions and even emotions, according to a paper published last month in the journal Scientific Report.

We’re going to put a Carbon nanotube computer in your hand


The silicon semiconductor industry has been going strong for more than 50 years. Like a steamroller, it has trundled over bumps and holes, while defying repeated warnings that it was running out of fuel or was about to be overtaken by flashier competitors.

3-D print hair, brushes, and fur


MIT researchers have invented a radical pixel-mapping printing technique by bypassing computer-aided design (CAD) software. They have quickly and efficiently modeled and printed thousands of hair-like structures.

Scientists are now using bacteria as living hard drives


Computers are becoming more like living beings. It looks like living beings are becoming more like computers. The latest research has demonstrated a method for storing lines of code in living bacteria, which can then be passed down to the next generation as genetic information.

Smart contact lens monitors diabetes and delivers drugs


Researchers have made a smart contact lens that could be used to monitor diabetes and dispense drugs on-demand. The system includes cool-looking eyeglasses that wirelessly power and communicate with the circuit-lined, drug-releasing lens that a patient could wear for up to a month.

Lithium-air catalyst could make car and phone batteries last five times longer


US and South Korean scientists discovered catalyst materials that could make it possible to create lithium-air (Li-Air) batteries that can potentially store five times more power than lithium-ion (Li-On) batteries do today. Lithium-air batteries work by taking oxygen from the air and then using it in chemical reactions that will produce electricity, rather than storing an oxidiser internally like lithium-ion batteries.

Harvard 3D laser printer prints metal structures mid-air by lasering nanoparticles


All futurists agree that consumer electronics of the future will be flexible, wearable and packed with sensors and antennas to perform a wide range of biomedical functions. This sound great, but unfortunately today’s production techniques are suitable for little more than flat, bulky and rigid devices.

Microscopic robots get tiny practical engines


Making machines smaller and smaller is becoming easier and easier to the point we can now make working machines that are only the size of complex molecules. The problem is making them work. Researchers have tried various power an propulsion systems, but they lack  speed, strength and control. However, with the creation of tiny engines, nanobots could be coming to living cells near you.

New nanowire battery can survive thousands of charges

Batteries haven’t seen a technological leap in years, mainly due to the volatile chemicals they contain. The most effective one produced being the lithium ion cell. Even with experimentation of exotic compounds the new wave of batteries is still many years away. Recently new research in the area of nanowires – surfaces “thousands of times thinner than a human hair” could prove to mitigate the short lifespan of batteries without needing any new chemicals.
