Chinese scientists develop new ‘reversible’ gene-editing technique

Posted by in categories: biotech/medical, genetics

Cas13 variants with minimal collateral effect are expected to be more competitive for in vivo RNA editing and future therapeutic applications, researchers claim.

Scientists from the Chinese Academy of Sciences (CAS) have allegedly developed a new “controllable, reversible and safer” gene-editing approach using CRISPR technology.

The system, named Cas13D-N2V8, showed a significant reduction in the number of off-target genes and no detectable collateral damage in cell lines and somatic cells, which indicated its future potential, according to a report published in South China Morning Post newspaper on Wednesday.

Who Gets to Work in the Digital Economy?

Posted by in categories: bioengineering, biotech/medical, business, computing, economics, employment, finance, internet

If the combination of Covid-19 and remote work technologies like Zoom have undercut the role of cities in economic life, what might an even more robust technology like the metaverse do? Will it finally be the big upheaval that obliterates the role of cities and density? To paraphrase Airbnb CEO Brian Chesky: The place to be was Silicon Valley. It feels like now the place to be is the internet.

The simple answer is no, and for a basic reason. Wave after wave of technological innovation — the telegraph, the streetcar, the telephone, the car, the airplane, the internet, and more — have brought predictions of the demise of physical location and the death of cities.


Remote work has become commonplace since the beginning of the Covid-19 pandemic. But the focus on daily remote work arrangements may miss a larger opportunity that the pandemic has unearthed: the possibility of a substantially increased labor pool for digital economy work. To measure interest in digital economy jobs, defined as jobs within the business, finance, art, science, information technology, and architecture and engineering sectors, the authors conducted extensive analyses of job searches on the Bing search engine, which accounts for more than a quarter of all desktop searches in the U.S. They found that, not only did searches for digital economy jobs increase since the beginning of the pandemic, but those searches also became less geographically concentrated. The single biggest societal consequence of the dual trends of corporate acceptance of remote work and people’s increased interest in digital economy jobs is the potential geographic spread of opportunity.

Neuralink’s brain-computer interface demo shows a monkey playing Pong

Posted by in categories: biotech/medical, computing, Elon Musk, finance, neuroscience

Neuralink, a company co-founded by Elon Musk, has been working on an implantable brain-machine interface since 2016. While it previously demonstrated its progress by showing a Macaque monkey controlling the cursor.

It’s unclear what kind of deal Musk has offered — whether it’s a collaboration or a financial investment —since none of the players responded or confirmed the report with the news organization.


Elon Musk’s last update on Neuralink — his company that is working on technology that will connect the human brain directly to a computer — featured a pig with one of its chips implanted in its brain. Now Neuralink is demonstrating its progress by showing a Macaque with one of the Link chips playing Pong. At first using “Pager” is shown using a joystick, and then eventually, according to the narration, using only its mind via the wireless connection.

Death, resurrection and digital immortality in an AI world

I have been thinking about death lately. Not a lot — a little. Possibly because I recently had a month-long bout of Covid-19. And, I read a recent story about the passing of the actor Ed Asner, famous for his role as Lou Grant in “The Mary Tyler Moore Show.” More specifically, the story of his memorial service where mourners were invited to “talk” with Asner through an interactive display that featured video and audio that he recorded before he died. The experience was created by StoryFile, a company with the mission to make AI more human. According to the company, their proprietary technology and AI can match pre-recorded answers with future questions, allowing for a real-time yet asynchronous conversation.

Hui Li, PhD, Discovers Gene Responsible for Deadliest Brain Tumor Also Causes Childhood Cancer

Posted by in categories: biotech/medical, neuroscience

Hui Li, PhD, a Department of Pathology researcher, along with his team discovered that a gene responsible for the deadliest type of brain tumor is also found to be responsible for two forms of childhood cancer. The new discovery may open the door to the first targeted treatments for two types of rhabdomyosarcoma, a cancer of the soft tissue that primarily strikes young children. Research also suggests the gene may play an important role in other cancers that form in muscle, fat, nerves and other connective tissues in both children and adults. Hui Li, PhD, and team published their findings in the scientific journal PNAS.

Technology promises to change the meaning of death

Posted by in category: biotech/medical

New research shows that we might be able to revive bodies we once thought beyond repair. That could increase medical inequities, but it’s still worth pursuing.
