Endoscopy-assisted magnetic navigation of biohybrid soft microrobots with rapid endoluminal delivery and imaging

Posted by in category: biotech/medical

High-precision delivery of microrobots at the whole-body scale is of considerable importance for efforts toward targeted therapeutic intervention. However, vision-based control of microrobots, to deep and narrow spaces inside the body, remains a challenge. Here, we report a soft and resilient magnetic cell microrobot with high biocompatibility that can interface with the human body and adapt to the complex surroundings while navigating inside the body. We achieve time-efficient delivery of soft microrobots using an integrated platform called endoscopy-assisted magnetic actuation with dual imaging system (EMADIS).

Researchers combines AI and robotic exoskeleton to make a self walking robotics exoskeleton

Posted by in categories: cyborgs, mobile phones, robotics/AI

Robotics researchers are developing exoskeleton legs capable of thinking and making control decisions on their own using artificial intelligence called ExoNet

THE PROBLEM

Current generation of exoskeleton legs need to be manually controlled by users via smartphones or joysticks, It has a problem where motors need to change their operating mode manually when they perform a new activity in different terrains.

New Apple Mixed-Reality Headset Details: Swappable Headbands, Eye-Tracking

Posted by in category: futurism

A mixed-reality headset Apple is developing will be equipped with more than a dozen cameras for tracking hand movements and showing video of the real world to people wearing it, along with ultra-high-resolution 8K displays and advanced technology for eye tracking, according to a person with direct knowledge of the device.

Those are among a bevy of features Apple is planning for the headset, a device that could represent one of the company’s most ambitious efforts to build a new technology platform. The Information viewed internal Apple images of a late-stage prototype from last year, which show a sleek, curved visor attached to the face by a mesh material and swappable headbands. An artist’s rendering based on the images of the headset and created by The Information appears below.

Ageing: Looming crisis or booming opportunity?

By 2050, the number of adults over the age of 65 globally will double, reaching a staggering 1.6 billion, with the largest growth in the developing world. This growth will be one of the greatest social, economic, and political transformations of our time, that will impact existing healthcare, government and social systems, that today are largely not inclusive of the ageing population or built to the scale needed to support it.

But we can begin to make investments in our support systems (enabled and scaled by technology) that encompass a coordinated response from governments, society, academia, and the private sector.

German scientist says 99.9% chance coronavirus leaked from Wuhan lab

Posted by in categories: biotech/medical, health

Wiesendanger points out that unlike SARS and MERS, no intermediate host between bats and humans has been found more than a year since the start of the pandemic. Thus far, there is no evidence for the zoonotic theory to explain the outbreak.

Indeed, during the joint China-WHO report issued on Feb. 9, Liang Wannian, head of the Chinese National Health Commission’s Expert Panel of COVID-19 Response, stated that 50000 samples of wild animals from 300 different species (including bats) as well as 11000 farm animals in 31 Chinese provinces — taken between November 2019 and March 2020 — had all tested negative for SARS-CoV-2, the virus which causes COVID-19.

New perovskite fabrication method for solar cells paves way to large-scale production

Posted by in categories: nanotechnology, solar power, sustainability

A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade.

“Our work paves the way for low-cost, high-throughput commercial-scale production of large-scale solar modules in the near future,” said Wanyi Nie, a research scientist fellow in the Center of Integrated Nanotechnologies at Los Alamos National Laboratory and corresponding author of the paper, which was published today in the journal Joule. “We were able to demonstrate the approach through two mini-modules that reached champion levels of converting sunlight to power with greatly extended operational lifetimes. Since this process is facile and low cost, we believe it can be easily adapted to scalable fabrication in industrial settings.”

The team invented a one-step spin coating method using sulfolane, a liquid solvent. The new process allowed the team, a collaboration among Los Alamos and researchers from National Taiwan University (NTU), to produce high-yield, large-area photovoltaic devices that are highly efficient in creating power from sunlight. These perovskite also have a long operational lifetime.
