Debate featuring Anders Sandberg on the future of human cloning

Posted by in category: biotech/medical

Anders Sandberg, a member of the advisory board for the Lifeboat Foundation, recently took part in a panel debate on the future of human cloning produced by the Institute of Art and Ideas.

Debate blurb:

Human cloning is anathema to most of us conjuring up Metropolis visions of identical humans serving tyrannical masters. But might this be a mistaken horror story? Could human cloning instead lead to medical breakthroughs and the end to infertility?

Tiny 3D-Printed Bio-Bots Are Propelled by Muscle Cells

Robots come in all shapes and sizes—some are mechanical, and some aren’t. Last year, a team of scientists from the University of Illinois at Urbana-Champaign made a seven-millimeter-long 3D printed robot powered by the heart cells of a rat.

The device, made of 3D printed hydrogel—a water-based, biologically compatible gel—had two feet, one bigger than the other. The smaller, longer foot was coated in heart cells. Each time the cells contracted, the robot would crawl forward a few millimeters.

Woman Grows A Nose On Her Spine After Stem Cell Experiment

Eight years ago, doctors took nasal tissue samples and grafted them onto the spines of 20 quadriplegics. The idea was that stem cells within the nasal tissue might turn into neurons that could help repair the damaged spinal cord, and the experiment actually worked a few of the patients, who regained a little bit of sensation. But it didn’t go well for one woman in particular, who not only didn’t experience any abatement in her paralysis, but recently started feeling pain at the site of the implant. When doctors took a closer look, they realized she was growing the beginnings of a nose on her spine, New Scientist reports.

Delivering Capsules of Stem Cells Helps Repair Injured Bones

For the recorder of potentially breakthrough medical technology, sometimes it seems that the list is just so many applications of three new technologies: smaller electronics, new materials and stem cells. Any electronic device set up to function inside the body relies on smaller, flexible parts and new biocompatible casings, for example. Stem cells, properly manipulated, seem capable of mending nearly everything that ails us.

But the details of how best to cultivate certain kinds of cells and spur them to function in the body are still being worked out. According to University of Rochester researchers, materials science may be a big help.

One trouble with stem cells is that they don’t stay put. When doctors put cardiovascular progenitor cells in the heart to heal damage from a heart attack, the cells are whisked away in the bloodstream in a matter of hours.

GMOs are not the problem, per se

Since giving my support to the May 24 march against Monsanto, I have taken the time to review some of the more unusual opinions in the debate over genetically-modified organisms (GMOs). The enthusiasts for technological development as a means of eliminating scarcity and disparity view GMOs favorably. These enthusiasts include Ramez Naam, whose book The Infinite Resource (2013) argues for human ingenuity as a sufficient force to overcome all resources shortages.
On the other end of the spectrum, alarmists like Daniel Estulin and William Engdahl argue that GMOs are actually part of a deliberate plot to burden poor nations and reduce their populations by creating illness and infertility. Such fringe figures in the alter-globalization movement regard big pharmaceutical companies, chemical companies and agri-giants as involved in a conspiracy to create a docile and dependent population. Are the opinions of either Naam or Estulin well-informed, or are they both too sensational?

Bulletproof Coffee, The New Power Drink Of Silicon Valley

Cloud computing pioneer Dave Asprey took a trip to Tibet in 2004 to learn how to meditate. But it was the yak-butter tea he tried there that ended up transforming his life.

“I had so much more energy and I didn’t feel sick at the altitude at all. I realized: There’s something going on here. I just felt so good, I’d never go back to a coffee maker with grinder combination” he remembers. He returned home and spent several years fiddling with ingredients, aiming for “a hot version of a Frappuccino without the milk and sugar.” He started with a base of coffee instead of tea because he’s an aficionado; he says he got his only undergraduate “A” the semester he discovered espresso. And the ban on milk and sugar was one of the many biohacks he had practiced over 15 years (and $300,000 in doctors and 3-D radioactive scans of his brain metabolism) trying to rid himself of “brain fog” and 100 pounds of extra weight.

Founders Fund Backs a Robotic Lab that Puts Science in the Cloud

Emerald Therapeutics is developing potential treatments for viral infections like HIV and HPV. But they’re not ready to talk about that yet.

What the stealth startup is ready to discuss is a tool they built in an effort to accelerate that work: A completely robotic lab that the company believes could aid other researchers as well, effectively serving as a kind of Amazon Web Services for science.

The nearly 20-person company has packed a 5,000-square-foot facility in a little office park in Silicon Valley with more than $2 million worth of mass spectrometers, automated pipettes and microscopes, capable of carrying out remote life sciences experiments under controlled conditions.

Deep brain stimulation as a treatment for epilepsy and movement disorders, most notably Parkinson’s disease, has rapidly gone from experimental to standard practice. With devices to provide delicate electro-stimulation to the brain now available and with maps of which neurons do what steadily gaining detail, attention is now shifting to using the approach to treat mental illness.

Mice With MS-Like Condition Walk Again After Human Stem Cell Treatment

Mice severely disabled by a condition similar to multiple sclerosis (MS) could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, will be published online on May 15, 2014, in the journal Stem Cell Reports.

When scientists transplanted human stem cells into MS mice, they expected no benefit from the treatment. They thought the cells would be rejected, much like rejection of an organ transplant.

Instead, the experiment yielded spectacular results.

Researchers use light to coax stem cells to regenerate teeth

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that is similar to bone and makes up the bulk of teeth. What’s more, they outlined the precise molecular mechanism involved, and demonstrated its prowess using multiple laboratory and animal models.
