A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry. The DNA double helix has been one of the most recognisable structures in science ever since it was first described by Watson and Crick almost 60 years ago (paper published in Nature in 25 April 1953).
Nobel Prize-winning scientist Thomas Steitz, Sterling Professor of Molecular Biophysics and Biochemistry, will receive the 2013 Connecticut (CT) Medal of Science, the state’s top prize for technological achievement crucial to economic development....
Like many Nigerians, MIT graduate student Chidube Ezeozue grew up frustrated by his nation’s erratic electrical grid. “Electrical outages are a huge problem in Nigeria,” says Ezeozue, who is pursuing dual master’s degrees in MIT’s Technology and Policy Program and in electrical engineering and computer science. “The outages really interrupt everyday life.” Nigeria’s supply of electricity is severely limited, resulting in r...
Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.
Yale University has been newly accredited to train physicians in the practice of addiction medicine. Yale’s program is among eight new fellowship programs at leading medical institutions that are receiving this accreditation....
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill (UNC) have developed a new tool to help surgeons use X-rays to track devices used in “minimally invasive” surgical procedures while also limiting the patient’s exposure to radiation from the X-rays.
Lattice Semiconductor Corporation announced the Sensor Extender reference design that offers a low-cost approach to remotely locate image sensors up to eight meters away from the image signal processor (ISP) and transmit and receive video signals at resolutions that range up to 720p60 and 1080p30.
Lumex announced the launch of its TitanBrite 2W UV LED. Available in a standard 405nm wavelength (purple), it is asserted to provide twice the power output of standard high power LEDs for a wide range of applications. The TitanBrite 2W UV LED (SML-LXL8047UVC Series) is said to
Mouser Electronics is now stocking the industry's smallest true bipolar +/-5V, 18-bit analog-to-digital converter from Maxim Integrated. MAX11156 SAR ADC offers excellent AC and DC performance with true bipolar input range.
Premier Farnell and Cypress Semiconductor announced today that customers can now pre-order the new PSoC 4 Pioneer Development Kit from element14. The powerful new kit costs only $25, and lets designers discover the capabilities of the new PSoC 4 programmable system-on-chip architecture....
Stephen Hawking, who spent his career decoding the universe and even experienced weightlessness, is urging the continuation of space exploration - for humanity's sake. The 71-year-old Hawking said he did not think humans would survive another 1,000 years "without escaping beyond our fragile planet."
We’ve written a lot on ECN about automotive safety and its intersection with cutting-edge technology. Texting, Facebooking, and web surfing pose an existential concern for distracted drivers (not to mention pilots, train conductors, and boat captains), but the nanny state has really overreached on this one: A California court recently found a motorist guilty of distracted driving for checking a map on his iPhone.
In a provocative new study, scientists reported Wednesday that they were able to “see” pain on brain scans and, for the first time, measure its intensity and tell whether a drug was relieving it. Though the research is in its early stages, it opens the door to a host of possibilities.
Yale will establish an Institute of Network Science to bring together researchers from many disciplines to advance the study of networks, President-Elect Peter Salovey announced April 11....
On April 11th JoVE will publish a new video article by Dr. Aydogan Ozcan demonstrating how a cell phone camera can capture images from a fluorescent microscope and flow cytometer, which will make it possible for areas with limited resources to easily run tests such as checking for contaminated water and monitoring HIV positive patients.
The Joint Trauma Analysis and Prevention of Injury in Combat program, formed in July 2006, brought together Defense Department intelligence, operational, medical, and materiel-development communities to improve DOD's understanding of vulnerabilities to threats and enable the development of improved tactics, techniques, and procedures and materiel solutions to prevent or mitigate traumatic injuries....
E-Switch announces a new long life sealed tactile switch, the TL6200. The TL6200 series tact switch offers a long operating life of 10 million cycles and is rated to IP67 standards. This tact switch comes in both SMT (gullwing) and thru hole termination options, and offers multiple actuator lengths.
Mouser Electronics announced it is stocking the world’s first round LED, the CBT-140 Big Chip Round LEDs from Luminus Devices. This new round emitting aperture provides the most efficient match for circular optical systems and narrow beam projectors.
A team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. For the first time, they developed a way to get around the severe distortions of high-energy X-ray beams that are used to image the structure of a gold nanocrystal.
DNA’s unique structure is ideal for carrying genetic information, but scientists have recently found ways to exploit this versatile molecule for other purposes: By controlling DNA sequences, they can manipulate the molecule to form many different nanoscale shapes. Chemical and molecular engineers at MIT and Harvard University have now expanded this approach by using folded DNA to control the nanostructure of inorganic materials. After...
The biggest thing in operating rooms these days is a million-dollar, multi-armed robot named da Vinci, used in nearly 400,000 surgeries nationwide last year - triple the number just four years earlier. But now the high-tech helper is under scrutiny over reports of problems, including several deaths that may be linked with it and the high cost of using the robotic system.
Mobility continues to be the hottest trend for the semiconductor and electronics industry. As though there were any need for supporting data, the major electronics shows from the first quarter of 2013 displayed and demoed the latest array of mobile devices.
Surgical robots could make some types of surgery safer and more effective, but proving that the software controlling these machines works as intended is problematic. Researchers have demonstrated that methods for reliably detecting software bugs and ultimately verifying software safety can be applied successfully to this breed of robot.
Scientists today described key advances toward practical uses of a new genre of tiny, biocompatible electronic devices that could be implanted into the body to relieve pain or battle infection for a specific period of time, and then dissolve harmlessly.
Advanced Power Solutions (APS) announces the release of the APS43MI / APS50MIG / APS63MI series of 2 x4” medical approved switching power supplies with the industry’s lowest profile of only 0.92” and single outputs ranging from 3.3~60VDC.
