A new device capable of pumping human waste into the "engine room" of a self-sustaining robot has been created by a group of researchers from Bristol.

Modelled on the human heart, the artificial device incorporates smart materials called shape memory alloys and could be used to deliver human urine to future generations of EcoBot a robot that can function completely on its own by collecting waste and converting it into electricity.

The device has been tested and the results have been presented today, 8 November, in IOP Publishing's journal Bioinspiration and Biomimetics.

Researchers based at the Bristol Robotics Laboratory a joint venture between the University of the West of England and University of Bristol have created four generations of EcoBots in the past 10 years, each of which is powered by electricity-generating microbial fuel cells that employ live microorganisms to digest waste organic matter and generate low-level power.

In the future, it is believed that EcoBots could be deployed as monitors in areas where there may be dangerous levels of pollution, or indeed dangerous predators, so that little human maintenance is needed. It has already been shown that these types of robots can generate their energy from rotten fruit and vegetables, dead flies, waste water, sludge and human urine.

A video of microbial fuel cells, fed on urine, charging a mobile phone can be viewed here - http://www.youtube.com/watch?v=4LTprRQTKAw

Lead author of the study Peter Walters, from the Centre for Fine Print Research, University of the West of England, said: "We speculate that in the future, urine-powered EcoBots could perform environmental monitoring tasks such as measuring temperature, humidity and air quality. A number of EcoBots could also function as a mobile, distributed sensor network.

"In the city environment, they could re-charge using urine from urinals in public lavatories. In rural environments, liquid waste effluent could be collected from farms."

At the moment conventional motor pumps are used to deliver liquid feedstock to the EcoBot's fuel cells; however, they are prone to mechanical failure and blockages.

The new device, which has an internal volume of 24.5 ml, works in a similar fashion to the human heart by compressing the body of the pump and forcing the liquid out. This was achieved using "artificial muscles" made from shape memory alloys a group of smart materials that are able to 'remember' their original shape.

When heated with an electric current, the artificial muscles compressed a soft region in the centre of the heart-pump causing the fluid to be ejected through an outlet and pumped to a height that would be sufficient to deliver fluid to an EcoBot's fuel cells. The artificial muscles then cooled and returned to their original shape when the electric current was removed, causing the heart-pump to relax and prompting fluid from a reservoir to be drawn in for the next cycle.

A stack of 24 microbial fuel cells fed on urine were able to generate enough electricity to charge a capacitor. The energy stored in the capacitor was then used to start another cycle of pumping from the artificial heart.

"The artificial heartbeat is mechanically simpler than a conventional electric motor-driven pump by virtue of the fact that it employs artificial muscle fibres to create the pumping action, rather than an electric motor, which is by comparison a more complex mechanical assembly," continued Walters.

The group's future research will focus on improving the efficiency of the device, and investigating how it might be incorporated into the next generation of MFC-powered robots.

Voters reward pragmatic, but limited government

DENVER (AP) — From the libertarian West to the conservative South to the liberal Northeast, Americans struck a moderate chord in a smattering of elections this week by signaling a willingness to accept government playing a role in their lives, provided it's not too dominant.

While there were too few races to suggest a national trend, the results do indicate that at least pockets of voters are seeking middle ground and rejecting two extremes: conservatives' staunch anti-government pitch and liberals' view that government is the best problem solver.

That could be instructive for lawmakers as a dysfunctional and divided Washington wrestles with philosophical questions about the federal budget and President Barack Obama's health care law heading into the 2014 midterm election year.

In New Jersey, Republican Gov. Chris Christie won as a Republican in a strong Democratic state by pitching himself as a practical conservative. He used his — and the federal government's — response to Hurricane Sandy to his benefit. Christie called his re-election a boon for voters "who didn't believe that government could work for them anymore."

His easy victory came just weeks after New Jersey voters elected Democrat Cory Booker, the Newark mayor who pitched himself as a non-ideological problem solver, to the U.S. Senate.

Virginians awarded their governor's job to Democrat Terry McAuliffe over Republican Ken Cuccinelli, a tea party favorite. McAuliffe is a longtime partisan power broker, but he emphasized government's role in helping create jobs to boost the economy, while hammering Cuccinelli's hardline conservatism on abortion, same-sex marriage and the recent government shutdown driven partly by GOP opposition to the health care overhaul.

In a south Alabama congressional district, Republicans voting in a special primary runoff rejected Dean Young, a combative tea party conservative, in favor of Bradley Byrne, a buttoned-down, longtime politician endorsed by the U.S. Chamber of Commerce and many local civic leaders. Almost defensively, Byrne called himself a "true conservative," but he talked about the need for a congressman to make government work and help with the district's economic development.

The middling trend carried over to ballot initiatives.

By a 2-to-1 margin, Colorado voters rejected a billion-dollar-a-year income tax hike in exchange for dramatic education changes that had U.S. Education Secretary Arne Duncan calling the state a national role model. But by the same margin, Colorado approved a 25 percent tax as part of regulating newly legal marijuana sales. And several local tax measures passed, with the notable exception of a proposed levy on sugary drinks.

Meanwhile, several Colorado counties rejected a symbolic referendum on seceding from the state because of dissatisfaction with policies from its more liberal, urban power centers.

Colorado political analysts the voters showed they share a national preference for pragmatic government action but are hesitant about the biggest, ideologically driven ideas with uncertain consequences.

Elsewhere, voters in Portland, Maine, and three Michigan cities adopted new legal protections for recreational amounts of marijuana. One of the last dry cities in Mormon-dominated Utah opted to allow beer sales, though they capped the alcohol content at 3.2 percent. Again, the results were moderation: Voters want freedom, but still give room for some regulation.

And several communities in Ohio and Colorado voted to suspend fracking, a burgeoning oil production technique, in their towns until lingering safety questions are answered, bucking arguments for free enterprise and development in an expensive ad campaign from the oil and gas industry. They essentially endorsed government being a check on the private sector.

Texas voters, meanwhile, voted to put a check on government by letting the private sector advance convention business in Houston and rejecting a bond sale that would have refurbished the Houston Astrodome into exhibition space.

On the philosophical question of whether the government is doing too much or taking about the right amount of action to solve problems, a slim majority of voters in Virginia and New Jersey exit polls said "too much," as they opted for candidates who tried to convince voters they are striking the right balance.

Those results mirror the 2012 presidential exit polls, when "too much" was the winner, even as Obama, the namesake of the sweeping health care law, won a second term.

The question is just what politicians do for voters with those seemingly contradictory preferences.

Purely for electoral purposes, Christie and McAuliffe clearly navigated the landscape, so well in Christie's case that some Republicans, like Utah Sen. Orrin Hatch, praised him as a 2016 White House contender who can overcome the GOP's struggles with women and non-white voters.

And many Democrats running in Republican-leaning states next year — Georgia governor candidate Jason Carter, Jimmy Carter's grandson; Kentucky Senate candidate Alison Lundergran Grimes; South Carolina governor candidate Vincent Sheheen — have embraced the "problem-solver" label saying that, of course, government plays a strong role in American life and the economy, particularly through schools and infrastructure.

Still, settling the policy questions is always harder.

Says James Thurber, a political science professor at American University: "It's especially difficult for Republicans with primaries" controlled by the most conservative voters. "But people are still looking for answers."

In Colorado, Democratic Gov. John Hickenlooper gave a nod to the challenge when talking about voters' rejection of the tax plan for education spending.

"This was the voters looking at an initiative that had the potential to transform public education," he said. "But it came with a price tag and people felt the price tag was too high. I don't think it's anything further than that."

Hubble spots strange asteroid with six tails of dust

This combination of Sept. 10 and 23, 2013 photos provided by NASA shows six comet-like tails radiating from a body in the asteroid belt, designated P/2013 P5. The Hubble Space Telescope discovered it in the asteroid belt between the orbits of Mars and Jupiter. A research team led by the University of California at Los Angeles believes the asteroid is rotating so much that its surface is flying apart. It’s believed to be a fragment of a larger asteroid damaged in a collision 200 million years ago. (AP Photo/NASA, ESA, D. Jewitt - UCLA)

CAPE CANAVERAL, Fla. (AP) — This is one strange asteroid.

The Hubble Space Telescope has discovered a six-tailed asteroid in the asteroid belt between the orbits of Mars and Jupiter. Scientists say they've never seen anything like it. Incredibly, the comet-like tails change shape as the asteroid sheds dust. The streams have occurred over several months.

A research team led by the University of California, Los Angeles, believes the asteroid, designated P/2013 P5, is rotating so much that its surface is flying apart. It's believed to be a fragment of a larger asteroid damaged in a collision 200 million years ago.

Scientists using the Pan-STARRS telescope in Hawaii spotted the asteroid in August. Hubble picked out all the tails in September.

The discovery is described in this week's issue of Astrophysical Journal Letters.

NEW YORK (AP) — Twitter had a strong public stock debut Thursday in the most highly anticipated initial public offering since Facebook's last year. That doesn't mean the people in the neighborhood near Twitter's headquarters are doing well.

Twitter is trading under the ticker symbol "TWTR." Twitter's stock opened at $45.10, or 73 percent above its $26 IPO price. The opening price values Twitter at more than $31 billion based on its outstanding stock, options and restricted stock that'll be available after the IPO. Expect some changes throughout the day, though: It has traded as high as $50.09 and is now at $48.21.

The high price comes despite the fact that Twitter has never turned a profit in seven years of existence. Revenue has been growing, but the company is also investing heavily in more data centers and hiring more employees.

Here's a running account of Twitter's first day of trading, presented in reverse chronological order. All times are EST.

___

— 3:05 p.m.: AP's @liedtkesfc explores the neighborhood outside @Twitter HQ and sees contrasts.

The San Francisco neighborhood outside Twitter's headquarters provides a forlorn contrast to the suddenly rich people working inside the building.

These are among the meaner streets in downtown San Francisco, long populated with the destitute who have no place to live and the miscreants who resort to crime to make ends meet. In hopes of cleaning the area up, the city of San Francisco gave Twitter local tax breaks on employee stock options to help persuade the company to move into the neighborhood two years ago.

But times are still tough here. Scruffy-looking people gathered against the wall of a post office across the street from Twitter's headquarters. Four of them had just spent the night in a homeless shelter. All of them said that they wished that they owned Twitter stock, yet they maintained that they didn't really envy Twitter employees becoming wealthier as the stock soared Thursday.

There was a clump of litter just a few feet away. Amid the empty coffee cups, cigarette butts and empty liquor bottles, there were two scratch-off games for the California lottery that had been discarded because they didn't pay off. #LandofBrokenDreams

— Michael Liedtke, San Francisco, @liedtkesfc

___

— 2:50 p.m.: In Asia, @Twitter has competition from local companies, reports AP's @YKLeeAP

Led by Japan, Indonesia, South Korea and India, Asia was the fastest growing region for Twitter in summer 2010, according to Semiocast, a Paris-based social media research company. But growth has slowed in South Korea and Japan, a red flag for Twitter as both countries are wealthy and have high rates of mobile device usage — now the predominant way Twitter is accessed.

New mobile applications from companies such as South Korea's Kakao Corp. and Japan's Line Corp., have experienced explosive growth, making them potent competitors for eyeballs and advertising.

Why are people leaving Twitter or spending less time on it?

Too open. Too crowded. Too difficult.

"In South Korea and Japan, open type social networking services like Twitter and Facebook are losing steam," said Justin Lee, an analyst of mobile messengers and games at BNP Paribas. "Closed social networking services where messages are shared among a small group of people will become more popular."

Twitter remains blocked from China's vast market but another giant, India, is open to Twitter. It has amassed 27 million users there, according to Semiocast. Yet Twitter acknowledged in IPO filings that low use of smartphones in emerging markets such as India could hamper the ability of advertisers to deliver compelling advertisements and hurt its earnings potential.

International users accounted for about three quarters of Twitter's members but only a quarter of revenue in the first nine months of this year. About 25 percent of Twitter's 232 million active users are in Asia.

— Youkyung Lee, Seoul, South Korea, @YKLeeAP

___

— 2:30 p.m.: @Twitter now among the most valuable media companies, notes AP's @rnakashi

Like Twitter, the other large media companies in the country rely to some extent on advertising revenue. As of mid-afternoon, Twitter's value is nearly $33 billion, after including options and restricted stock that'll be available after the IPO.

The market value of other media companies: CBS Corp., $34.7 billion; Discovery Communications Inc., $30 billion; Viacom Inc., $38.8 billion; The Walt Disney Co., $120 billion; Time Warner Inc. $60.3 billion.

— Ryan Nakashima, Los Angeles, @rnakashi

___

— 2:10 p.m.: @NYSEEuronext has congratulated @Twitter "on a successful #NYSEIPO! We're excited to be your partner."

___

— 1:55 p.m.: Looking back at Twitter's IPO price, here are some quick facts from @Dealogic

Twitter priced its IPO at $26, raising $1.82 billion. If the offering's underwriters fully exercise their option to buy more shares, the IPO's value will rise to $2.09 billion. That would make it the second-largest Internet IPO by an American company on record, following Facebook Inc.'s $16 billion, but beating Google Inc.'s $1.92 billion.

The research firm Dealogic says Twitter's IPO is set to be the third-largest U.S.-listed IPO so far this year, behind Plains GP Holdings at $2.9 billion and Zoetis' $2.6 billion.

Including Twitter, U.S.-listed tech industry IPOs have raised $7.8 billion through 41 deals so far this year. That's down from $20.5 billion generated by 35 deals during the same period of 2012, though Facebook accounted for $16 billion of the 2012 total.

Tech companies tend to post bigger first-day jumps than the overall market. The average one-day jump for tech industry IPOs this year is 35 percent, compared with an average gain of 17 percent for 2013 IPOs overall. Twitter's stock opened at 73 percent above the IPO price.

— Bree Fowler, New York, @APBreeFowler

___

— 1:40 p.m.: @Twitter soars while drop in overall market pulls down rest of Internet cos.

Twitter shares are flying high, but other Internet companies are having a tough time getting off the ground.

While Twitter's debut likely helped send shares of Facebook Inc. down, the overall tech industry also took a hit as the markets pulled back from record levels on worries that the Federal Reserve could soon start curtailing its economic stimulus program.

Facebook shares fell $1.07, or 2.2 percent, to $48.05 after dropping as low as $47.41 earlier in the day. Other Internet companies such as LinkedIn Corp., AOL Inc., Google Inc., Pandora Media Inc. and Zillow Inc. all posted small to moderate losses.

— Bree Fowler, New York, @APBreeFowler

___

— 1:20 p.m.: Will Twitter's stock keep going up? There is risk of Twitter burnout. #TwitterHaters

There's plenty of evidence online about the celebrities who tire of Twitter. The long list of Twitter quitters includes everyone from Alec Baldwin to Miley Cyrus to "Lost" co-creator Damon Lindelof, though some eventually return.

Some get overwhelmed by followers spewing hatred. Others get addicted to interacting with huge fan bases and need to pull away. Even non-celebrity users complain of the amount of time spent posting and replying and vow to close accounts to get on with their lives.

With its public stock debut, the company has been selling potential investors on the idea that its user base of 232 million will continue to grow along with the 500 million tweets that are sent each day. The company's revenue depends on ads it inserts into the stream of messages.

But Wall Street could lose its big bet on social media if prolific tweeters lose their voice.

— 1:05 p.m.: Twitter chairman @jack makes reference to first tweet in Vine video post

About two hours ago, Twitter chairman and co-founder Jack Dorsey tweeted this: "just setting up our $twtr —https://vine.co/v/hI1nP3vQOBI" The link is to video on Twitter's Vine app, showing traders shouting on NYSE trading floor.

The tweet, of course, is a reference to the world's first tweet, which was sent by Dorsey on March 21, 2006, and read "just setting up my twttr." Dorsey uses "$twtr" in Thursday's post in a reference to the stock's ticker symbol. Putting a dollar sign before it is a common way to refer to stocks on Twitter.

— Barbara Ortutay, New York, @BarbaraOrtutay

___

— 12:50 p.m.: @Twitter is trading very heavily in its first day on @NYSE.

About 82 million shares of Twitter have exchanged hands already. To put that in perspective, Twitter only sold 70 million shares in its IPO. One way to think about it, every share issued in Twitter's IPO has been traded more than once, and the session isn't half over yet.

Of course, not every investor who got shares of Twitter at the $26 IPO price is selling Thursday. Many large institutional investors are buy-and-hold firms. If every investor had sold at the debut, the stock would not have opened at 73 percent above the IPO price.

— Ken Sweet, New York, @KenSweet

___

— 12:35 p.m.: @TDAmeritrade official says stock debut is flawless

"It's gone on pretty flawlessly," says JJ Kinahan, chief strategist at online brokerage TD Ameritrade.

For one, he says, the broader market's downturn isn't affecting Twitter much. Trading is also tight, rather than volatile, which indicates that people feel like it was "pretty fairly priced," he says.

— Barbara Ortutay, New York, @BarbaraOrtutay

___

— 12:15 p.m.: Learn more about @vivienneharr, @sirpatstew and @bostonpolice official who rang @NYSEEuronext opening bell

Crediting its success to its users, Twitter gave the honor of ringing Thursday's opening bell at the New York Stock Exchange to three high-profile tweeters: a child activist, a legendary British actor and a Boston Police official.

Nine-year-old Vivienne Harr used a lemonade stand to raise more than $100,000 to support efforts to eliminate child slavery around the world. Her pink lemonade, along with a ginger-infused version, is now being bottled and sold online. A portion of the profits is donated to groups that work toward ending child slavery. More than 22,000 people follow @vivienneharr on Twitter.

Patrick Stewart is known both for his Twitter presence and his stage and screen careers. His highest profile roles have included Captain Jean-Luc Picard in "Star Trek: The Next Generation" and Professor Charles Xavier in the "X-Men" movies. About 722,000 people follow @sirpatstew. Stewart tweeted a picture of himself on Halloween dressed as a lobster in a bathtub. It was retweeted nearly 39,000 times.

Cheryl Fiandaca has been chief of public information for the Boston Police Department since July 2012. Fiandaca spearheaded the department's social media efforts, and her department used Twitter to get information to the public in the aftermath of the Boston Marathon bombings. More than 266,000 people follow @bostonpolice.

— 11:55 a.m.: @Wedbush analyst @MichaelPachter says high debut price suggests #TwitterIPO was managed well.

Wedbush analyst Michael Pachter says the surge "clearly shows that demand exceeds supply of shares."

"It's impossible to know what the real value is," he says.

Still, he acknowledges that the price is "pretty high" and not something he was expecting.

— 11:45 a.m.: It's #BusinessAsUsual at @Twitter headquarters, though employees seem happy.

Although Twitter's fortunes are already soaring on Wall Street, there haven't been any audible whoops of joy emanating from the company's San Francisco headquarters yet. But almost every employee walking in and out of the building is grinning.

Twitter seems to know that it needs to accelerate its revenue growth to support its lofty stock price. A few employees just came out to usher in a group of advertising agency representatives. #TheNewReality

— 11:30 a.m.: @Barclays official in charge of stock debut speaks with AP's @KenSweet, admits being "a little nervous."

It was the biggest IPO of the year for Glenn Carell, the Barclays Capital official in charge of Twitter's stock debut. He has been doing it for 21 years and says, "I was a little nervous, but it went well."

Twitter hired Barclays to be its "designated market maker," which supervises the trading of a company's stock on the New York Stock Exchange. The IPO process itself was managed by three other investment banks.

___

— 11:05 a.m.: RT @KenSweet: Twitter took a long time to open due to the deal size. Goldman also likes to take its time.

___

— 10:10 a.m.: AP market reporter @KenSweet explains the role @Barclays has in #TwitterIPO.

Trading for Twitter's stock is under the supervision of Barclays Capital. Twitter hired the bank to be its "designated market maker." A DMM supervises the trading of a company's stock. He or she is an experienced trader in charge of ensuring that buying and selling go smoothly. If trading becomes volatile, the DMM can step in and buy shares using his or her firm's own money.

DMMs are especially important the day a company goes public, because the DMM coordinates between Twitter, the company's investment banks and NYSE's floor traders to get a stock trading. If technical problems arise, the NYSE uses DMMs to bypass electronic trading systems, allowing humans to trade a company's stock. That is not possible on all-electronic stock exchanges such as the Nasdaq, which had technical problems during Facebook's IPO last year.

Barclays' role as Twitter's DMM does not mean it is in charge of the entire IPO process. That role falls to Twitter's investment banks: Goldman Sachs, Morgan Stanley and JPMorgan Chase.

___

— 10 a.m.: #TwitterIPO first indication for opening price: $42-46.

That means Twitter could start trading at up to 77 percent above its IPO price. Trading is to begin soon as representatives from Barclays continue negotiations to find the right price.

— Ken Sweet, New York, @KenSweet

___

— 9:50 a.m.: With the #Ring of the #NYSEBell past, what will happen? @KenSweet reports.

Traders gather around Twitter's booth on the floor of the New York Stock Exchange. At Twitter's post, the company's "designated market maker" starts taking orders from the traders, who are representing dozens of firms and hundreds of investors.

The goal of the DMM, who used to be known as the NYSE's specialists, is to figure out what is the best price to start trading Twitter's shares.

Due to massive investor and media interest in Twitter, the actual negotiation over what are the right price for Twitter's now-public shares will take some time. It could take as little as 20 minutes, or it could take an hour. The NYSE wants to avoid the trading debacle that Nasdaq faced with last year's Facebook's IPO, so it's going to be careful.

IPO is behind Thanksgiving, Texas, NFL and #throwbackthursday.

RT @KenSweet: Orders for Twitter have been coming in since 8 am, floor trader Jonathan Corpina tells me. Very busy.

RT @KenSweet: Corpina expects a smooth opening. The NYSE does IPOs all the time, he says. The difference here is volume and media attention.

RT @KenSweet: Traders use these handheld wireless computers to send orders. Paper orders ended a long time ago: pic.twitter.com/bwz8UK4xcB

___

— 8:40 a.m.: Why Twitter went to @nyse. Pressure is on with opening bell less than an hour away. #lessonsfromFB

Twitter chose to go public on the NYSE over the all-electronic Nasdaq. One of the reasons why Twitter likely chose the NYSE over the Nasdaq has to do with problems Facebook faced with its Nasdaq-listed IPO last year. A glitch in Nasdaq's trading software led to trading delays and order failures on Facebook's first day of trading.

The NYSE isn't taking any chances with Twitter. The exchange tested its trading software on Oct. 26 to prepare for Twitter's debut. If the NYSE faces technical problems with its ordering software, the exchange can switch over the traditional human-based stock trading that dominated Wall Street for decades.

RT @KenSweet: NYSE traders and execs are really playing up the human element to this IPO. It's a shot across the bow at the Nasdaq.

— 8:20 a.m.: AP markets reporter @KenSweet says media outnumber traders 5:1 @nyse trading floor

It's a media madhouse. But it's still more than an hour before the opening bell, so more traders should be coming. Expect a big crowd.

RT @KenSweet: The NYSE is decorated head to toe. with twitter logos. They went big here to promote: pic.twitter.com/pnwRQ9e6QG

___

— 8 a.m.: After #TwitterIPO pricing, market debut comes Thursday.

It should come as no surprise that Twitter used Twitter to announce its public stock debut.

It began with a tweet on Sept. 12: The 7-year-old company posted on its official Twitter account that it has "confidentially submitted an S-1 to the SEC for a planned IPO." Details about offering emerged after the IPO documents were released publicly later.

On Oct. 24, Twitter set its IPO price target at $17 to $20 per share. It raised that to $23 and $25 per share, signaling an enthusiastic response from prospective investors. The actual price on Wednesday night was even higher, at $26. That bodes well for the company's stock when trading begins.

Twitter also took to Twitter to announce that price: https://twitter.com/twitter/status/398235511254298624/photo/1

The company is offering 70 million shares in the IPO, plus an option to buy another 10.5 million. If all shares are sold, the IPO will raise $2.09 billion, making it the biggest IPO for an Internet company since Facebook raised $16 billion last year.

Of course, Facebook made its debut with high hopes, only to see its stock fall below the IPO price by the second day of trading. Twitter has valued itself at just a fraction of Facebook and sought to cool expectations in the months and weeks leading up to the offering.

Apple posts two EFI updates for late 2013 MacBook Pros with Retina Displays

Apple on Thursday posted two firmware updates for the late 2013 MacBook Pro with Retina Display - MacBook Pro Retina EFI Update v1.2 and MacBook Pro Retina EFI Update v1.3.

The 1.2 update is specifically aimed at models equipped with Nvidia graphics, and updates a problem that, "in rare cases, may limit the performance of the discrete graphics processor after a system wake or boot."

The 1.3 update is recommended specifically for 13-inch models, and fixes an issue that cause the built-in keyboard and Multi-Touch trackpad to become unresponsive.
