Space architects have unveiled a concept for a 3D-printed Moon base called SinterHab near the lunar south pole. Modules would be constructed from lunar dust by microwave sintering and contour crafting, built by a large NASA spider robot.
Unlike an earlier, more bulky concept using a mobile printing array of nozzles on a 6 meter frame to spray a binding solution (glue) onto… read more
An implantable gel material that can release drugs in response to pressure applied by a patient has been developed by researchers at the National Institute for Materials Science (NIMS) in Japan.
Oral administration of drugs may be difficult for patients experiencing nausea during cancer chemotherapy, for diabetics (to release insulin), and for other conditions.
The idea is for this controlled-release system is for a doctor… read more
Neuroscientists at Howard Hughes Medical Institute have mapped the activity of nearly all the neurons in a vertebrate brain at cellular resolution, with signficant implications for neuroscience research and projects like the proposed Brain Activity Map (BAM).
The researchers used high-speed light sheet microscopy to image the activity of 80% of the neurons in the brain (which is composed of ~100,000 neurons) of a fish… read more
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient energy sources.
Scientists at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory used LCLS, together with computerized simulations, to reveal surprising details of a short-lived early state in a chemical reaction occurring at the… read more
BIOFAB, based in Emeryville, California, which calls itself “the world’s first biological design-build facility,” has announced availability of DNA sequences that allow precise control of gene activity in the bacterium Escherichia coli, Nature News reports.
Launched in 2009 with a US$1.4-million grant from the National Science Foundation, BIOFAB aims to advance synthetic biology by creating standard biological ‘parts’ in the form of DNA… read more
University of Wisconsin-Madison scientists have transplanted neural cells derived from stem cells from a monkey’s skin into its brain and watched the cells develop into several types of mature brain cells.
After six months, the cells looked entirely normal, and were only detectable because they initially were tagged with a fluorescent protein.
The transplanted cells came from induced pluripotent stem cells (iPS cells), which can, like embryonic stem… read more
Institute of Bioengineering and Nanotechnology (IBN) researchers have engineered an artificial human liver that mimics the natural tissue environment closely.
The development makes it possible for companies to predict the toxicity of new drugs earlier, potentially speeding up the drug development process and reducing the cost of manufacturing.
The liver is an important target organ for drug testing because all drugs pass through it… read more
Ed Boyden, a faculty member in the MIT Media Lab and the McGovern Institute for Brain Research, was named a recipient of the 2013 Grete Lundbeck European Brain Research Prize. The 1 million Euro prize is awarded for the development of optogenetics, a technology that makes… read more
Where their grandparents may have left behind a few grainy photos, a death certificate or a record from Ellis Island, retirees today have the ability to leave a cradle-to-grave record of their lives, The New York Times reports.
Two major forces are driving virtual immortality. The first and most obvious: inexpensive video cameras and editing programs, personal computers and social media sites like Facebook, Twitter and YouTube.… read more
A unique new cancer treatment uses gene therapy to induce a cancer-fighting immune response whose intensity can then be controlled with a pill. The combination could help tailor treatment to a patient’s individual response, MIT Technology Review reports.
The treatment uses the body’s own cells or tumor cells to produce extra copies of a naturally occurring hormone-like molecule called IL-12, which regulates anticancer immune responses. Last week,… read more
Paramount Pictures has acquired screen rights to Nexus, the science fiction novel by Ramez Naam, to be produced by Mary Parent of Disruption for Darren Aronofsky’s Protozoa.
The author, former CEO of Apex Nanotechnology, is the author of the nonfiction book More Than Human: Embracing The Promise Of Biological Enhancement.
Here’s the plot from Amazon:
In the near future,… read more
Duke University experiments in connecting the brains of two rats through implanted electrodes and the planned Brain Activity Map project reflect a growing Pentagon interest in neuroscience for applications that range from such far-off ideas as teleoperation of military devices (think mind-controlled drones), to more near-term and less controversial technology, like prosthetics controlled by the human brain, BBC Future reports.… read more
Life as we know it is based primarily on the elements carbon and oxygen.
Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe.
They’ve found that when it comes to supporting life, the universe leaves very little margin for error.
Both carbon and oxygen… read more
Autism is thought to result from abnormal cell communication. Testing a new theory, researchers at the University of California, San Diego School of Medicine have used a newly discovered function of an old drug called suramin — used medically for the treatment of African sleeping sickness — to restore cell communications in a mouse model of autism, reversing symptoms of the devastating disorder.
The findings… read more
Students in countries like India and Brazil have been signing up in droves for these massive open online courses, or MOOCs, offered for free from top-tier universities, such as Stanford, MIT, and Harvard.
Yet in the world’s poorest regions, where even reliable high-speed Internet access capable of streaming course lecture videos is hard to come by, delivering a useful education to the masses is clearly not a straightforward operation,… read more
