Mark Zuckerberg discusses Facebook’s new COVID-19 tracking site

Posted by in category: biotech/medical

#News, #Covid

Facebook CEO Mark Zuckerberg on Monday unveiled a coronavirus ‘heat map’ powered by Facebook data which is aimed at helping track the spread of the disease and plan for reopening society. The first map (pictured) is based on more than two million responses to surveys which asked users in the US to self-report symptoms over a period of 10 days in April.

New AI algorithm brings us closer than ever to controlling machines with our minds

Posted by in categories: biotech/medical, cyborgs, information science, robotics/AI

Researchers from Carnegie Mellon and the University of Pittsburgh today published research showing how they’d solved a frustrating problem for people who use a brain-computer interface (BCI) to control prosthetic devices with their thoughts.

While the research itself is interesting – they created an algorithm that keeps the devices from constantly needing to be re-calibrated to handle the human brain’s fluctuating neuronal activity – the real takeaway here is how close we are to a universal BCI.

BCIs have been around for decades in one form or another, but they’re costly to maintain and difficult to keep working properly. Currently they only make sense for narrow use – specifically, in the case of those who’ve lost limbs. Because they’re already used to using their brain to control an appendage, it’s easier for scientists and researchers to harness those brainwaves to control prosthetic devices.

Bactericidal nanomachine: Researchers reveal the mechanisms behind a natural bacteria killer

Posted by in categories: biotech/medical, food, nanotechnology

In a study published in Nature, a UCLA-led team of researchers describe how the nanomachine recognizes and kills bacteria, and report that they have imaged it at atomic resolution. The scientists also engineered their own versions of the nanomachine, which enabled them to produce variations that behaved differently from the naturally occurring version.

Their efforts could eventually lead to the development of new types of antibiotics that are capable of homing in on specific species of microbes. Drugs tailored to kill only a certain species or strain of bacteria could offer numerous advantages over conventional antibiotics, including lowering the likelihood that bacteria will develop resistance. In addition, the tailored drugs could destroy harmful cells without wiping out beneficial bugs in the gut microbiome, and they could eventually offer the possibilities of being deployed to prevent bacterial infections, to kill pathogens in food and to engineer human microbiomes so that favorable bacteria thrive.
