“For the average American consumer, 3D printing is ready for showtime,” said Associate Professor Joshua Pearce.
The reason is financial: the typical family can already save a great deal of money by making things with a 3D printer… read more

Measurements tell us that global average sea level is currently rising by about 1 inch per decade. But in an invisible shadow process, our long-term sea level rise commitment or “lock-in” — the sea level rise we don’t see now, but which carbon emissions and warming have locked in for later years — is growing 10 times faster, and this growth rate is accelerating, writes Ben… read more
Engineers at the California Institute of Technology (Caltech) have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope.
Such a system could greatly improve the efficiency of digital pathology, in which specialists need to review large numbers of tissue samples. By making it possible to produce robust microscopes at low cost,… read more
A new technique for developing more targeted drugs with reduced side effects by using “molecular automata” — a mixture of antibodies and short strands of DNA — has been demonstrated by Hospital for Special Surgery (HSS) and Columbia University researchers.
These short DNA strands, aka oligonucleotides, can be manufactured by researchers in a laboratory for any user-specified sequence.
How it works
All cells… read more

Researchers have developed a new method that can look at a specific segment of DNA and pinpoint a single mutation, which could help diagnose and treat diseases such as cancer and tuberculosis.
Modern genomics has shown that just one mutation can be the difference between successfully treating a disease and having it spread rampantly throughout the body.
These small mutations can be the root of a… read more

MIT researchers, in collaboration with physicist Yves Couder at the Université Paris Diderot and his colleagues, report that they have produced the fluidic analogue of a classic quantum experiment, in which electrons are confined to a circular “corral” by a ring of ions.
Tests of the new cladding material, a ceramic compound called silicon carbide (SiC), are described in a series of papers appearing in the journal Nuclear Technology.
A substitute for traditional zircaloy could greatly reduce the danger of hydrogen explosions.… read more

Silk has walked straight off the runway and into the lab. According to a new study published in the Journal of Clinical Investigation, silk implants placed in the brain of laboratory animals and designed to release a specific chemical, adenosine, may help stop the progression of epilepsy.

“See-saw” molecule may offer clues to potential therapies in the long-term.
More than 11,000 Americans suffer spinal cord injuries each year, and since over a quarter of those injuries are due to falls, the number is likely to rise as the population ages.
The reason so many of those injuries are permanently disabling is that the human body lacks the capacity to regenerate nerve fibers. The best our… read more
Study may advance fundamental understanding of how brain cells communicate.
Brain cells talk to each other in a variety of tones. Sometimes they speak loudly but other times struggle to be heard.
For many years scientists have asked why and how brain cells change tones so frequently. National Institutes of Health researchers showed that brief bursts of chemical energy coming from rapidly moving power… read more

Motivational analysis conducted by Columbia Business School and University of Pittsburgh professors forecasts the Twitter medium becoming comparable to television.
New research from scholars at Columbia Business School and the University of Pittsburgh questions the sustainability of Twitter, the social network that has more than 500 million registered users. The research was recently published in the journal Marketing Science.
Columbia Business School Professor… read more

Impressive examples of new non-invasive optical techniques using lasers, light-emitting diodes (LEDs), and spectroscopic methods to probe and render images from beneath the surface of the skin are featured in a newly completed open-access special section in the Journal of Biomedical Optics published by SPIE, the international society for optics and photonics.
The techniques may be used in a wide variety of medical and cosmetic… read more
Princeton University researchers have created “souped up” versions of the calcium-sensitive proteins that for the past decade or so have given scientists an unparalleled view and understanding of brain-cell communication.
Reported July 18 in the journal Nature Communications, the enhanced proteins developed at Princeton respond more quickly to changes in neuron activity, and can be customized to react to different, faster rates of neuron activity.… read more
University of Akron researchers have developed nanoscale “giant surfactants” (using nanopatterning to combine functioning molecular nanoparticles with polymer surface films and liquid solutions) that could lead to smaller chips, lighter laptops, slimmer televisions, and crisper smartphone visual displays.
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid.
The giant surfactants developed at… read more
