#Promising technique improves hydrogen production of affordable alternative to platinum Scientists have demonstrated that microwaves can help create nanostructured molybdenum disulfide (Mos2) catalysts with an improved ability to produce hydrogen.
This exposes a larger fraction of reactive sites along the edges of these surfaces where hydrogen can be produced.
Atomistic first-principles calculations show that the increase in spacing between the layers changes the electronic and chemical properties of these edge sites,

#Google to become Alphabet Inc in shakeup Google Inc (GOOGL. O) announced a major shake-up of its operating structure on Monday, creating a holding company called Alphabet
which will contain subsidiaries to separate its core web advertising business from newer ventures like driverless cars.
The move appeared to be an attempt to let the search engine giant focus on its more creative and ambitious projects,
while investors cheered the potential for more financial disclosures of its disparate business segments.""It suggests that in all likelihood,
Google is not going to slow the pace of their experimental processes like self driving cars, "said Michael Yoshikami,
The surprise news sent shares of Google up as much as 7 percent to $708 in after hours trading."
Google's planned structure resembles the way companies like Berkshire hathaway and General electric are organized, with a central unit handling corporate-wide activities such as finance
the Google unit will encompass the core search engine traditionally associated with the company as well Google maps and Youtube.
Alphabet Inc will replace Google as the publicly traded entity and all shares of Google will automatically convert into the same number of shares of Alphabet, with all of the same rights."
"This new structure will allow us to keep tremendous focus on the extraordinary opportunities we have inside of Google,
"said current Google CEO Larry page in a blogpost. Analysts also said the new structure could herald a new era of fiscal discipline and transparency in some of its more experimental and opaque business units.
In a SEC filing, Google said the new arrangement will take effect later this year and that it will likely result in two reportable, financial segments."
"For example, if a unit is doing well or badly they can dial it up or down,
The shuffle also looked to have the markings of Ruth Porat, who joined Google as its chief financial officer in March from Morgan stanley. In Google's recent quarterly conference call, Porat repeatedly emphasized keeping expenses under control.
Porat will serve as the CFO of both Alphabet and Google. Page will serve as the CEO of the newly created holding company and Sundar Pichai,
a long-time Google executive who most recently served as the company's senior vice president of products, will head Google.
The company's current directors will become directors of Alphabet. Google cofounder Brin will become president of Alphabet,
and Eric Schmidt will be executive chairman. Analysts said the move, which was mainly about transparency

#Forget Bluetooth, new wireless technology uses your body to transmit data Bluetooth redefines ubiquitous. It seemingly everywhere,
and nowhere more so than in personal wearable devices such as fitness trackers, smart watches, audio headsets, earphonesyou name it.
But what if it not the best technology for the job? Researchers at the University of California, San diego in the US have developed a prototype to show off a new wireless communication technique which they say massively outperforms existing wireless tech by using the human body itself to help send data between devices.
The researchers call their new method agnetic field human body communication The technique uses the body as a vehicle to deliver magnetic energy between wearable electronic gadgets.
For the system to function and propagate magnetic fields through the body, the wearable device needs to be circular in nature (like the coil shown in the image above),
Whereas Bluetooth devices worn on the body transmit data via radio signals, the electromagnetic radiation that makes up these signals is blocked by something you.
The end result is that Bluetooth devices aren very power efficient when we wear them something youe more than likely to have had personal experience with
and it a problem that only compounded by the fact that most wearable Bluetooth gadgets are small and light,
The researchers say path loss using magnetic field human body communication is more than 10 million times lower than that of Bluetooth radios. his technique,
to our knowledge, achieves the lowest path losses out of any wireless human body communication system that been demonstrated so far,
in a statement. his technique will allow us to build much lower power wearable devices. If youe concerned about
They say that ultra-low-power communication systems in wearable devices will transmit signals of much less power than things like MRI SCANNERS and wireless implant devices, with magnetic fields passing freely and harmlessly through biological tissue.

A computer scientist in the UK has invented a new type of chess artificial intelligence that's able to get up to the International Master level after just 72 hours of tuition.
Chess-playing computers aren't new of course-IBM's Deep Blue scored the first AI triumph over a human world champion by beating Garry Kasparov in 1997-but Lai's approach works differently.
This neural network approach adapts over time and mimics the human brain. Essentially, modern day chess programs use'brute force'to beat human players,
with minimal hand-crafted knowledge given by the programmer";"he also says it's"the most successful attempt thus far at using end-to-end machine learning to play chess".

"Making light-based computers isn as simple as replacing electrons with light particles-or photons-in current computers.
when the data reaches our computer. This slows everything back down again and consumes a whole lot of extra energy,
Instead, we need to completely redesign the way our computers work, running them on light instead of electricity,
and this new light-based computer chip brings us one step closer to that goal. Known as photonic memory, light-based memory is not a new concept,
Not only have previous attempts at light-based computer chips turned out to be quite volatile, theye all required power to store data,
and unless wee prepared to keep our computers on, you know, forever, that not exactly practical.

researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New south wales (UNSW) in Australia have overcome the final hurdle,
by creating a quantum logic gate in silicon-the same material that today's computer chips are made from.
which means they now have the ability to build the world's first quantum processor chip and, eventually, the first silicon-based quantum computer.
Right now, regular computer chips store information as binary bits, which are either in a 0 or 1 state.
which isn't compatible with today's silicon-based computer infrastructure. A silicon quantum logic gate was the last physical building block remaining to be built
"Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,

when they try to seek out relevant medical information on the Internet. Unfortunately, as many of us are aware,
the web is not necessarily a great place to do this kind of research, and now a broad study of anti-vaccination websites helps to explain why.
Researchers from the Johns hopkins university Bloomberg School of Public health analysed close to 500 anti-vaccination websites and found that they deliver a distorted mixture of pseudoscience and misinformation to parents seeking information about vaccines.
According to the researchers, more than two thirds of anti-vaccination websites present nonscientific information and other forms of misinformation as cientific evidenceto support the view that vaccines are dangerous to children,
and nearly one third of sites reinforce the idea through the use of anecdotes and stories.
The researchers used search engines including Google, Bing, Yahoo and Ask jeeves to find the sites, using search terms like mmunisation dangersand accine dangerto see where it led them.
The study found that the resulting mix of blogs, personal websites Facebook pages and health sites perpetuate an alarming mixture of misinformation about vaccines
and use a range of persuasive techniques to get the reader on side. Almost two thirds of the sites suggested that vaccines cause autism,
and more than 40 percent claim theye responsible for rain injury The majority present information as scientific when it doesn actually qualify for that distinction.
In addition to condemning vaccines, the sites also promote some positive behaviours, such as healthy eating (recommended by 18.5 percent of anti-vaccination sites),
and the benefits of breastfeeding (5. 5 percent) and eating organic food (5. 2 percent). The study, presented this week at the American Public health Association annual meeting in Chicago,
may help actual scientists such as doctors and health care workers better understand how to reach and communicate with parents who are concerned genuinely about any perceived risks of vaccination
(and who may be exposing themselves to potentially dangerous misinformation on these kinds of sites). he biggest global takeaway is need that we to communicate to the vaccine-hesitant parent in a way that resonates with them
and is sensitive to their concerns, said Meghan Moran, an associate professor in the Bloomberg School department of health, behaviour and society. n our review,
