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.

This scientific breakthrough has just been published in the prestigious journal Nature Nanotechnology in an article titled “Magneto-aerotactic bacteria deliver drug-containing nanoliposomes to tumour hypoxic regions.” The article notes the results of the research done on mice, which were successfully administered nanorobotic agents into colorectal tumours.

“These legions of nanorobotic agents were actually composed of more than 100 million flagellated bacteria — and therefore self-propelled — and loaded with drugs that moved by taking the most direct path between the drug’s injection point and the area of the body to cure,” explains Professor Sylvain Martel, holder of the Canada Research Chair in Medical Nanorobotics and Director of the Polytechnique Montréal Nanorobotics Laboratory, who heads the research team’s work. “The drug’s propelling force was enough to travel efficiently and enter deep inside the tumours.”

Anti-inflammatory drug mefenamic acid completely reversed memory loss and brain inflammation in mice genetically engineered to develop symptoms of Alzheimer’s disease and amyloid beta-induced memory loss, a team led by David Brough, PhD, from the University of Manchester has discovered.

The non-steroidal anti-inflammatory drug (NSAID) drug targets an important inflammatory pathway called the NLRP3 inflammasome, which damages brain cells, according to Brough. This is the first time a drug has been shown to target this inflammatory pathway, highlighting its importance in the disease model, Brough said.

Esta descoberta pode abrir a próxima fronteira da descoberta biológica com a pavimentação de uma nova maneira para, imagiologia nanoscopic super-resolução sem rótulo e expandir a compreensão dos processos biológicos.

A surgical procedure that involves drilling holes and injecting stem cells into stroke patients’ brains seems to have contributed to a wheelchair-bound stroke patient regaining the ability to walk. Despite the major recovery exhibited by patients, further study must be made to investigate the true impact.

Researchers from Stanford University were “stunned” at the positive results they obtained after injecting stem cells directly into stroke patients’ brains. The discovery has created a talking point in the neuroscience community, causing researchers to re-visit and re-evaluate the notion that brain damage is permanent and irreversible.

IBM’s TrueNorth, a so-called “cognitive chip,” remarkably resembles the human brain: its 4,096 cores combine to create about a million digital neurons and 256 million synapse connections. In short, like everyone’s favorite complex organ, it operates extremely quickly and consumes far less energy than typical processors. Samsung has taken the chip and plugged it into its Dynamic Vision Sensor (DVS) to process digital imagery at a blindingly fast rate.

Typical digital cameras max out 120 frames per second, but a DVS-equipped gadget can capture an incredible 2,000 fps. Unlike a conventional sensor, each pixel on Samsung’s only reacts if it needs to report a change in what it’s seeing, according to CNET. That high speed could be useful for creating 3D maps or gesture controls. At a press event on Thursday in San Jose, the company demonstrated its ability to control a TV as it recognized hand waves and finger pinches from ten feet away.

DVS is efficient like its TrueNorth chip base, and only consumes about 300 milliwatts of power. That’s about a hundredth the drain of a laptop’s processor and a tenth of a phone’s, a Samsung VP said at the event. But we still have a ways to go before we approach the minimal power requirements of the human brain, he said, which can process some tasks at 100 million times less power than a computer.

Lookout world Chine Tech is rising and nothing or no one will stop it now. The real question is how soon with the world’s tech valley hub be in China? The US has enjoyed for many decades being the world’s top technology center. However, China for the past 20+ years has been executing their world footprint in owning the title as the top global economic power. In the past we have seen them take over consumer goods manufacturing, pharma (especially generic drugs), and the latest is tech. Wonder what is next?

TOKYO — China has jumped to the front ranks of the supercomputing powers, with its Sunway TaihuLight, powered by domestically developed chips, recently recognized as the fastest computer in the world.

In its debut on the Top500 list of the world’s fastest supercomputers in June, the Sunway TaihuLight overwhelmed such rivals as the Tianhe-2, a Chinese supercomputer powered by Intel chips that has claimed the No. 1 spot on the past six Top500 lists. Furthermore, it was the first time for China to surpass the U.S. in the total number of systems on the list.
