Sci-fi author has brain cryogenically frozen so it can be reanimated in the future

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.

Cyborg Heart Patch Replaces Dead Cardiac Tissue with Combination of Healthy Cells, Electronics
Posted by Karen Hurst in categories: biotech/medical, cyborgs, electronics, health
Scientists at Tel Aviv University in Israel have developed a “cyborg heart patch” for replacing injured cardiac tissue. There has been considerable research on creating scaffolds seeded with cardiac cells, but simply delivering a bunch of cells in a neat package produces underwhelming results. The new patch developed at TAU integrates electronics alongside the cellular scaffold to both monitor and influence the activity of the cells.
The device can record intercellular electrical activity and deliver pulses to make the cardiomyocytes contract to a defined beat. Additionally, the researchers demonstrated that the electrodes within the patch can be covered with drugs to provide controlled release of medication right to the nearby heart cells.
This is certainly an impressive achievement that may herald a truly therapeutic approach for treating cardiac infarcts and other conditions of the heart.

Light Activated Bio-Bots Powered by Live Muscle Cells (VIDEO)

Biologically powered robots may one day be used to perform surgical procedures, deliver drugs, and maybe to even make humanoid overlords for us mortals. A big step toward that was taken by researchers at University of Illinois at Urbana-Champaign who used light-activated muscle cells as the power source to make tiny bio-bots.
The optogenetic technique published in Proceedings of the National Academy of Sciences relies on genetically engineered mouse muscle cells that were made to contract in response to blue light. Rings of these cells were placed around a 3D printed flexible rods of different lengths between two and seven millimeters. When light was illuminated over the mechanism, the biobots contracted and walked in a certain direction. Various lengths and configurations were tried to achieve the best walking results. Moreover, the researchers were able to change the direction of the walking bio-bot.
