Bacteria-powered Bio-Bots Avoid Obstacles on Way to Target
Posted by Karen Hurst in categories: biotech/medical, robotics/AI
Microscopic robots, powered by bacterial flagellation, are a curious branch of robotics research, potentially leading to devices that can deliver drugs, perform surgical tasks, and help out with diagnostics. While bacteria has been harnessed in the past to power small devices, having those devices actually navigate to a desired target has been a challenge. At Drexel University researchers are now using electric fields to help their bacterial biobots detect obstacles and float around them on their way to the final destination.
The electric fields don’t actually control the bots, but allow the bots to sense their environment and to move around. The devices are powered by rod-shaped S. marcescens bacteria that are normally negatively charged. The researchers positioned two electric fields orthogonally to each other, creating a grid. Obstacles within the grid slightly affect the fields’ shape, which the robot recognizes and uses to avoid the obstacles.
Here are a couple videos demonstrating the bacterial powered microbot:

BioDesign Studio Lets You Tinker With Biology to Make Something New
Posted by Karen Hurst in categories: biotech/medical, computing
Now this is a cool concept; a studio that allows others to experiment and build their own Biocomputer, and other biotechnologies.
How does a leopard get its spots? A new exhibit at The Tech Museum of Innovation in San Jose has some clues about that.

Sci-fi author has brain cryogenically frozen so it can be reanimated in the future
Posted by Montie Adkins in categories: biotech/medical, cryonics, life extension, neuroscience
If I am not mistaken she edited The Three Body Problem, she did not write it.
In what seems like a story ripped straight from the pages of an Isaac Asimov novel, a recently deceased Chinese woman named Du Hong just had her brain cryogenically frozen in hopes that, in the future, the technology to bring her back to life will be created. No joke. Hong, a science fiction author herself, paid upwards of $120k to have her brain sent from China to Scottsdale, Arizona to undergo a freezing procedure at the Alcor Life Extension Foundation. Her idea is that while modern tech doesn’t allow for the reanimation of her brain today, inevitable advancements in cryonics will one day bring her back to life.
Before passing away last May from pancreatic cancer, the 61-year-old Du decided she wanted to allow her brain to be the subject of experiments after her death. Though it took some time before the team at Alcor actually conducted the procedure, doctors in Beijing prepped Du’s brain after her official time of death on May 30. Despite the Alcor Life Extension Foundation agreeing to freeze Du’s brain, the organization made it clear that it wouldn’t be the one to actually attempt to bring Du back to life in the future.

Kuwait has become the first country to make DNA testing mandatory for all residents
Posted by Shailesh Prasad in categories: biotech/medical, government, law enforcement
In a controversial move, Kuwait has passed a law making it mandatory for all its 1.3 million citizens and 2.9 million foreign residents to have their DNA entered onto a national database.
Anyone who refuses to submit their DNA for testing risks one year in prison and a fine of up to US$33,000, and those who provide a fake sample can be jailed for seven years.
The decision came after an Islamic State-led suicide bombing in Kuwait City on 26 June, which killed 26 people and wounded 227 more. The government hopes that the new database, which is projected to cost around US$400 million, will make it quicker and easier to make arrests in the future.

Necrogenomics: Gathering DNA From the Dead to Improve the Lot of the Living
Posted by Karen Hurst in categories: biotech/medical, health
This one kind of gives me the heebie geebies.
DNA sequencing of the deceased could lead to a number of advances in health care. A group of scientists in Denmark have launched a proposal to create the world’s first national necrogenomic database.
The idea that dead men tell no tales is about to be seriously put to shame, should a newly suggested DNA registry in Denmark become reality.
