Researchers say coronavirus likely spread silently in Washington for weeks

Posted by in category: biotech/medical

Wuhan coronavirus pandemic — washington state.

Scientists suggest it has spread in King County for 6 weeks already.

“That being so, Bedford and other researchers believe the virus has likely been spreading through the community undetected for close to six weeks. Researchers estimate that could mean anywhere from 150 to 1,500 people have been infected here, with the most likely number being between 300 and 500.”

Cyborgs, Robots, And Biohackers: The First-Ever Survey of Transhumanism

Posted by in categories: biotech/medical, cyborgs, life extension, neuroscience, robotics/AI, transhumanism, wearables

the photo series by vintner and fletcher illustrates three gradual stages of transhumanism from ‘testing ground’, ‘patient zero’ to ‘humanity 2.0’. at the lowest tier, ‘testing ground’ looks into individuals who have created wearable technology to expand their human abilities, improving everything from concentration to mental health.‘patient zero’ studies those who have taken permanent action to become half human and half robot. in the final chapter, ‘humanity 2.0’, the transhumanist subjects focus on life extension and immortality.

Scientists Have Proven That Negativity Makes Cancer Grow Inside The Body

Posted by in categories: biotech/medical, health

negativity makes cancer grow
Everybody feels negative emotions once in a while, but these emotions have a stronger effect on your health than you may realize. Every time you think about regrets, experience resentment or replay bad memories in your head, your body suffers just as much as your mind. That’s why harboring negative emotions can lead to devastating long-term disease.

But there is one simple solution: forgiveness. Trouble is, our culture seems to perceive forgiveness as a sign of weakness, submission, or both. This makes it harder to actually do the work to forgive people who’ve done you harm.

New platform for engineering ribosomes to ‘cook new cuisines’

Posted by in categories: bioengineering, biotech/medical

Synthetic biology researchers at Northwestern University have developed a system that can rapidly create cell-free ribosomes in a test tube, then select the ribosome that can perform a certain function.

The system, called synthesis and evolution (RISE), is an important step toward using ribosomes beyond their natural capabilities. The key feature of RISE is the ability to evolve ribosomes without cell viability constraints. The result could be new ways to synthesize materials, like nylon, or therapies, like that could address rising antibiotic resistance.

“Ribosomes have an extraordinary capability as the protein synthesis machinery of the cell,” said Michael Jewett, Walter P. Murphy Professor of Chemical and Biological Engineering and director of the Center for Synthetic Biology at Northwestern’s McCormick School of Engineering, who led the research. “But to synthesize proteins beyond those found in nature, we have to design and modify the ribosome to work with non-natural substrates. Developing ribosomes in vitro is an important part of that system, and we are very excited to have this new capability.”

Coronavirus genome structure and replication

Posted by in category: biotech/medical

Curr Top Microbiol Immunol. 2005;287:1–30.

In addition to the SARS coronavirus (treated separately elsewhere in this volume), the complete genome sequences of six species in the coronavirus genus of the coronavirus family [avian infectious bronchitis virus-Beaudette strain (IBV-Beaudette), bovine coronavirus-ENT strain (BCoV-ENT), human coronavirus-229E strain (HCoV-229E), murine hepatitis virus-A59 strain (MHV-A59), porcine transmissible gastroenteritis-Purdue 115 strain (TGEV-Purdue 115), and porcine epidemic diarrhea virus-CV777 strain (PEDV-CV777)] have now been reported. Their lengths range from 27,317 nt for HCoV-229E to 31,357 nt for the murine hepatitis virus-A59, establishing the coronavirus genome as the largest known among RNA viruses.
