3D-printing human embryonic stem cells for drug testing, future replacement of human organs

New 3D printing process is first to print the more delicate (and more useful) hESCs
February 6, 2013

3D printing with embryonic stem cells (credit: )

A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.

The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more

Facebook, CNN, and the rise of social voting

July 13, 2012

CNN and Facebook have joined forces to make the “I’m Voting” Facebook app, which enables Facebook users to endorse candidates and issues, and to commit to voting.

If you use the app and commit to voting for someone, that information appears in your timeline, news feed, and real-time ticker.

During CNN’s political coverage this fall, CNN personalities will use the app to poll users on issues.

Google isn’t just the backbone of the Internet anymore, writes Steve Kovach at Business Insider.

“It’s rapidly becoming the backbone of your entire life, all thanks to data you’re voluntarily giving up to a private company based on your Web searches, photos, Gmail messages, and more. …

“It’s the most apparent in Google Now, a voice-powered personal assistant that launched on Android phones last year.” [...]

Battery dead in the middle of a phone call and you left your charger home, or worse, you’re on a camping trip. Sound familiar?

No prob, just grab some nanosilicon powder, mix with water, and zap: instant hydrogen fuel to generate recharge current — thanks to University at Buffalo researchers, who have discovered that super-small particles of silicon react with water to produce hydrogenread more

NASA video on LENR (low energy nuclear reactions), a clean form of nuclear energy

January 13, 2012

NASA Langley Research Center posted Thursday (but has not announced) a new video on NASA research on LENR (low energy nuclear reactions), entitled “Method for Enhancement of Surface Plasmon Polaritons to Initiate & Sustain LENR.”

The research focuses on “another way of producing energy-efficient nuclear power,” says NASA Senior Research Scientist Joseph Zawodny, featured in the video (posted on YouTube by KurzweilAI). “This other form of nuclear power releases… read more

Automated drug design using synthetic DNA self-assembly

Using a simple “drag-and-drop” computer interface and DNA self-assembly techniques, Parabon NanoLabs researchers have developed a new automated method of drug development that could reduce the time required to create and test medications, with the support of an NSF Technology Enhancement for Commercial Partnerships grant.

“We can now ‘print,’ molecule by molecule, exactly the compound that we want,” says Steven Armentrout, the principal investigator… read more

IBM invests $3 billion to extend Moore’s law with post-silicon-era chips and new architectures

IBM announced today it is investing $3 billion for R&D in two research programs to push the limits of chip technology and extend Moore’s law.

The research programs are aimed at “7 nanometer and beyond” silicon technology and developing alternative technologies for post-silicon-era chips using entirely different approaches, IBM says.

IBM will be investing especially in carbon nanoelectronics, silicon photonics, new memory technologies, and architectures that support quantum… read more

“I’ve experienced both sides” of the privacy debate on Google Glass, Nick Bilton writes in The New York Times.

But other gadgets have plenty of privacy-invading potential too, he says. Memoto, a tiny, automatic camera that looks like a pin you can wear on a shirt, can snap two photos a minute and later upload it to an online service.

Memory implants

A maverick neuroscientist believes he has deciphered the code by which the brain forms long-term memories
May 1, 2013

Teodore Berger, a biomedical engineer and neuroscientist at the University of Southern California in Los Angeles, envisions a day in the not too distant future when a patient with severe memory loss can get help from an electronic implant, MIT Technology Review reports.

In people whose brains have suffered damage from Alzheimer’s, stroke, or injury, disrupted neuronal networks often prevent long-term memories from forming. For more than… read more

Today’s new iPad introduction was Apple’s most important event of the year.

I iPad is the future of Apple and potentially the future of the personal computer.

Today’s new iPad continued two important trends for Apple:

The iPad maintained its lead as the best tablet on the market in terms of hardware, software, and ecosystem, the retina display — unmatched by the competition… read more

Dear science fiction writers: stop being so pessimistic!

March 21, 2012

Neal Stephenson

Stephenson has seen the future — and he doesn’t like it.

Today’s science fiction, he argues, is fixated on nihilism and apocalyptic scenarios — think recent films such as The Road and TV series like “The Walking Dead.” Gone are the hopeful visions prevalent in the mid-20th century.

So in Fall 2011, Stephenson launched the Hieroglyph project to rally writers to infuse science fiction with… read more

Turning off the stem-cell aging switch

Researchers at the Salk Institute for Biological Studies have uncovered a series of biological events that implicate stem cells’ “niche” (surroundings) as the culprit in loss of stem cells due to aging.

Their findings have implications for treatment of age-related diseases and for the effectiveness of regenerative medicine.

Stem cells are essential building blocks for all organisms, from plants to humans. They can divide… read more
