Sony's new SmartWatch 2 doesn't get as much attention — and doesn't do as much — as Samsung's Galaxy Gear computerized wristwatch. But for the things it does, Sony's version performs better. The SmartWatch 2 is also 33 percent cheaper, at about $200, and works with a variety of Android phones, not just Sony's.
The government is speeding up research on safety systems that automatically prevent drivers from operating their cars if they are drunk or aren't properly buckled in. Officials also said Thursday that they expect to decide by year's end how to encourage automakers to make some special safety systems already in certain high-end vehicles available in more cars.
In deciding how best to meet the world’s growing needs for energy, the answers depend crucially on how the question is framed. Looking for the most cost-effective path provides one set of answers; including the need to curtail greenhouse-gas emissions gives a different picture. Adding the need to address looming shortages of fresh water, it turns out, leads to a very different set of choices.
In the past two decades, the Hubble Space Telescope has produced thousands of staggering images of the universe — capturing colliding galaxies, collapsing stars, and pillars of cosmic gas and dust with its high-precision cameras. These images have driven many scientific discoveries, and have made their way into popular culture, having been featured on album covers, fashion runways, and as backdrops for sci-fi television episodes. With...
Back in 1991, Nature published a picture from the IMAX movie Antarctica, along with the caption: "Emperor penguins may be waddling jokes on land, but underwater they can turn into regular rockets…accelerating from 0 to 7 m/s in less than a second."
Stanford University scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device – a silicon semiconductor coated in an ultrathin layer of nickel – could help pave the way for large-scale production of clean hydrogen fuel from sunlight, according to the scientists.
A new study of gun violence in Chicago, led by Yale sociologist Andrew Papachristos, reveals that a person’s social network is a key predictor in whether an individual will become a victim of gun homicide, even more so than race, age, gender, poverty, or gang affiliation....
A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science....
Richardson RFPD, Inc. today announces immediate availability and full design support capabilities for four new broadband RF gain blocks from Analog Devices, Inc. (ADI). The new gain blocks are single-ended RF/IF gain block amplifiers that operate from 30 MHz to 6 GHz and offer up to 24 dB gain and 40 dBm third-order intercept point (OIP3).
Available immediately from MicroPower Direct, the ML600xRU series provides 6W of output power in a miniature SMT package. They provide the robust performance, miniature size and economy required by a wide range of space critical board level applications. Available on tape/reel, they can be used with most automated assembly systems.
The comment period for the proposed revisions to the Defense Federal Acquisition Regulation System (DFARS) ended on July 15, 2013. This important piece of legislation, which is expected to go into effect in the first quarter of 2014, is the culmination of several years of effort by lawmakers to deal with the problem of counterfeit electronic components.
International Rectifier introduced the IR3891 and IR3892 SupIRBuck integrated dual output voltage regulators designed for space-constrained netcom, server and storage applications. The new dual output devices are optimized for single rail operation from 5V to 12V inputs or 1V to 21V input with external 5V bias.
As international climate negotiators meet this month for the 19th meeting of the UN Conference of Parties (COP19), there’s an increasing realization that top-down efforts to confront climate change aren’t working — or at least, they’re not working quickly enough. Are there ways that large groups of people — even a global community— could work together to take action now? That was the focus of an MIT climate conference last week, titled “Crowds an...
When you squeeze atoms, you don't get atom juice. You get magnets. According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise.
An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment.
