Non-Stick Surface On Med Devices Could Keep Bacteria At Bay

60-Second Science

In lab tests, catheters coated with a non-stick surface harbored far fewer Staph bacteria than conventional devices. Gretchen Cuda Kroen reports.

More 60-Second Science

Nasty bacteria cling to the surfaces of countertops. They also stick to medical devices?like catheters?that are placed inside the human body, where they can become a dangerous source of infection.

Individually, bacteria are fairly easily killed. But if they multiply on a surface, they eventually form a biofilm?a tightly organized bacterial community that can fight off antibiotics and the body?s immune system.

Now, researchers have come up with a way to give those nasty bugs the ?slip?? a non-stick surface that stops the biofilm from forming. The material hasn?t been tested in humans yet. But in the lab, catheters coated with the non-stick surface stayed almost completely free of Staphylococcus aureus bacteria. The findings were presented at the October, 2012, AVS International symposium in Tampa, which covers materials, interfaces and processing. [Andrew Hook et al, Combinatorial Discovery of Materials That Resist Bacterial Adhesion]

By denying bacteria a grip on medical devices without resorting to antibiotics, the researchers also hope to help doctors get a grip on antibiotic resistance?one of medicine?s stickiest problems.

Romney Makes Last-Ditch Play For Pennsylvania

It's a tradition for Republican presidential candidates to pour money into Pennsylvania with little to show for it -- the state hasn't picked a Republican for the office in 24 years. But a week before the election, the Romney campaign says it is making a serious play for the Keystone State.

In a memo released Tuesday, campaign manager Rich Beeson argued that Pennsylvania is a "unique opportunity" for Romney. And the campaign seems to be putting its money where its mouth is, placing statewide ad buys that should begin airing on television Wednesday, according to the Associated Press.

"The western part of the Keystone State has become more conservative (and President Obama's war on coal is very unpopular there), and Mitt Romney is more competitive in the voter-rich Philadelphia suburbs than any Republican nominee since 1988," the memo states. "This makes Pennsylvania a natural next step as we expand the playing field."

Recent polls show that the Romney campaign may be on to something. Romney began to gain on President Obama in September and that continued in October after his strong performance in the first debate. The TPM PollTracker Average has Obama leading Romney by just three points.

Since Romney's post-debate bounce, the campaign has claimed that the momentum in the race remains with the former governor, a strategy that the Pennsylvania ad buys fits into as well. But the Obama campaign called Romney's proclaimed efforts to expand the map a bluff.

"The Romney campaign wants you to think it's expanding the map, but it's not," Obama campaign manager Jim Messina said on a conference call with reporters Monday, after news that a super PAC supporting Romney was running ads in Minnesota and Pennsylvania. "They tried this before: a month ago they were going to surge in Michigan, then they weren't. A couple of weeks ago too they were going to surge in Maine...then they weren't."

Nevertheless, the Obama campaign will also begin running ads in the Philadelphia and Pittsburgh markets in a response to the super PAC. On Monday, the campaign said it would do this out of an abundance of caution.

If a last-ditch Republican effort to win Pennsylvania sounds familiar, that's because Sen. John McCain did it in 2008. Two weeks before that election, McCain's political director held a conference call with reporters in which he argued McCain had a good shot at winning the state even though polls at the time generally showed McCain trailing Obama by 10 to 15 points. Ultimately, Obama won the state by 10 points.

Though 2012 is not 2008, this is the scenario the Obama campaign recalled in their response to Romney's Pennsylvania effort.

"Three things are now absolutely clear in this race - we have a significant early vote advantage in states from North Carolina to Nevada, there is no Romney momentum in the battleground states, and the Romney campaign has found itself with a tremendously narrow and improbable path to 270 electoral votes," Messina said in a statement Tuesday, responding to new Romney ad buys. "Now, like Republicans did in 2008, they are throwing money at states where they never built an organization and have been losing for two years."

Romney's first ad in Pennsylvania touts his commitment to the coal industry -- and arguing that the state's coal industry has suffered under Obama:

President Sata has began the contruction of his retirement home-HH

TIME PUBLISHED - Wednesday, October 31, 2012, 1:40 pm

UPND leader Hakainde Hichilema addresses journalists after attending the meeting

UPND leader Hakainde Hichilema addresses journalists after attending the meeting

United Party for National Development (UPND) Leader Hikainde Hichilema has accused President Michael Sata of beginning the construction of his retirement home at a cost of K1.4 billion while he is a sitting president. According to the statement, this action is a violation of the republic constitution which only provides such privilege to a former head of state.

Below is the full statement

?

Press Statement
31st October, 2012

Early this year, we alerted the nation that Mr. Sata had begun constructing his retirement home near state lodge illegally using government resources.

Government spokesperson Hon Kennedy Sakeni refuted our assertion and alleged that we were bitter and chocking with envy after the 2011 electoral defeat.

Lies have a very short life span and we have been vindicated.

Mr. Sata sent his uncle Hon Alexander Bwalya Chikwanda as a bearer of a message to Parliament to solicit for K1.4 billion for the construction of his house. Page 911 of the yellow book attest to this.

Our contention is that our laws do not provide for such type of expenditure. This is a clear violation of our statutes. Act number 21 of 1998, chapter 15 section 4a states as follows:

?assigned to a former President within a period of not more than two years from the date of ceasing to hold office, a furnished executive house built or bought in Zambia by the State at a place of the former President?s choice?.

Clearly, this is a benefit given to a former President not a sitting one. Is Mr. Sata a retired, sitting President? We are concerned that Mr. Sata has continued raping our constitution with impunity. If Mr. Sata had any sense of morality, he would have concentrated on paying retirees who have already worked for their money than paying himself a retirement prematurely.

We call on all Honourable Members of Parliament across political divide to do the honourable thing by stopping this reckless, proposed spending.

This level of self aggrandizement is unacceptable especially that houses for the second, third and fourth former Republican Presidents are not completed. If this reckless expenditure is not stopped in Parliament, UPND shall explore other democratic options available.

Hakainde Hichilema
PRESIDENT

Putting All Of This ?Fanboy/Fangirl? Nonsense To Rest Once And For ...

There?s an interesting thing that happens in the technology press world, and probably throughout all of journalism land. It?s weird, and it?s become quite annoying to me. Basically, whenever someone writes something positive about a company, be it a product release or software update, the general public tends to jump to a conclusion quickly ? that the person writing the story is either a fanboy/fangirl of the company, or is in the ?pocket? of the PR team at said company.

It?s obnoxious. The sad part about it is that this behavior of simple-mindedness is starting to cross over into the journalism ecosystem itself. Other journalists at other publications are starting to call out people for ?drinking Kool-aid? or being an ?apologist.?

Even though this is very annoying and counterproductive, the sadder part is that it?s so far from the truth that it?s not even funny. For whatever reason, whether you agree with it or not, we are paid to write about technology. For the most part, we call it like we see it. At least I know I do, and can?t speak for others. Oh, and we don?t get paid by companies to write things. Ever. We?re not stupid.

My experience in Silicon Valley is a bit different than other journalists? experiences because I?ve actually worked at startups and have had a few of my own projects. I know how all of this works, and trust me, it?s work. Launching something, reaching out to the press and supporting your users is tireless work, but that?s what we get paid to do at startups.

For journalists? We?re people too. We like certain products and companies. We get called out for having a bias toward something. Well, duh. We?re human and we like what we like and we don?t like what we don?t like. It?s life and more importantly, it?s completely healthy.

Example time

So if you?re oblivious to all of this and don?t know what I?m talking about, I?ll give you a few examples. The best one that I can think of is any journalist that covers Apple heavily. Some journalists get called out for being in their ?back pocket.? Not only is that not true, but it?s quite hurtful and questions our integrity. Should we fight back? No. Sometimes we have to, though.

Another example is a journalist at a publication that covers Facebook heavily. It?s their beat, they are very interested in what Facebook is up to. Sometimes, when the company screws up, they call them out on it. Like a journalist should. But sometimes, they get really excited to tell you, the readers, that Facebook has done something quite awesome and revolutionary. As they should.

In my experience, I get called out repeatedly for covering a company that isn?t Apple. For what reason? I have no idea, other than they?re not ?sexy enough? in Silicon Valley. The heart of the matter is that all of these companies are made up of people who work very hard to create things that change your lives and in some cases, change the world.

It?s really awesome and inspiring stuff. What?s even awesomer is that we have the job to tell you all about it.

Don?t get me wrong

I love commenters and readers, so don?t get me wrong here. I love feedback and criticism. Everyone is entitled to their own opinions. That?s why the world and the Internet are great. However, lay off on attacking integrity unless you have evidence that this is really the case.

I?m not afraid to tell you that this is annoying or obnoxious, because I have no shits to give. I will not apologize for enjoying things that a company does and thus enjoying telling you about it. You can hate it. I hope that people do sometimes, because if you agree with one person all of the time, something is very wrong.

I?m a fan of Apple products, but?I hate iOS 6 Maps?and have said as much. I don?t like everything that Google does. In fact,?some of their moves baffle me, but some of them are?quite fantastic. It?s life.

Having said all of this, I just wanted to level with folks on how this all really works. We?re all very lucky to be able to find information quickly and read great publications for free. We don?t have to like what we read. We don?t have to like who wrote it. We don?t have to like who it is about. But you do have to know that we?re all people.

Just because we?re behind a computer doesn?t mean we get a free pass to be an ass. Rock on and feel free to bash me in the comments.

Romney woos Florida early vote; Obama eyes N.H.

LAND O'LAKES, Fla. (AP) ? Juggling politics and storm preparations, Mitt Romney dangled a plea for bipartisanship before early voters in Florida on Saturday as Barack Obama worked to nail down tiny New Hampshire's four electoral votes. Both campaigns scrambled to steer clear of a most unlikely October surprise, a superstorm barreling up the East Coast.

With just 10 days left in an extraordinarily tight race, Hurricane Sandy had both campaigns ripping up carefully mapped-out itineraries as they worked to maximize voter turnout and avoid any suggestion that they were putting politics ahead of public safety.

The campaigns pressed every possible angle in search of advantage ? even paying attention to punctuation.

Obama's campaign signs for months have said: "Forward." Now they say: "Forward!"

Romney, who has been striking a more moderate tone as he courts women and independents in the campaign's home stretch, campaigned across Florida with a pledge to "build bridges" with the other party.

He coupled that message with digs at Obama for "shrinking from the magnitude of the times" and advancing an agenda that lacks vision. Noting that Obama supporters like to chant "four more years" at the president's campaign rallies, Romney picked up on his crowd's own chant at the Pensacola Civic Center and said: "I like '10 more days' a lot better."

His warm-up act was more biting: Sen. Marco Rubio, R-Fla., told the crowd that Obama was advancing "the ideas of countries that people come here to get away from." Pressed later on what countries he was referring to, Rubio said, "any big-government country in the world" and specifically referred to Mexico and Latin America.

Obama hauled his campaign to New Hampshire, where he told volunteers at a Teamsters hall in Manchester that: "We don't know how this thing is going to play out. These four electoral voters right here could make all the difference."

It takes 270 electoral votes to win the election. Obama is ahead in states and the District of Columbia representing 237 electoral votes; Romney has a comfortable lead in states with 191 electoral votes. The rest lie in nine contested states that are too close to call, New Hampshire among them.

The president adjusted his campaign speech at a Nashua rally to appeal to voters in low-tax New Hampshire, hammering Romney for raising taxes and fees as governor of neighboring Massachusetts.

Obama accused Romney of running in Massachusetts on a pledge to lower taxes, then making life more expensive for the middle class after taking office.

"All he's offering is a big rerun of the same policies," Obama told a crowd of 8,500 gathered at an outdoor rally on an unseasonably warm October day.

The president said Romney even raised fees in Massachusetts on obtaining a birth certificate, "which would have been expensive for me." It was a veiled reference to opponents of the president who have incorrectly said he was born outside the United States. Copies of his birth certificate have been in high demand.

The candidates worked to lock down every possible early vote without intruding on emergency preparations as the storm's expected track looked to affect at least four battleground states: North Carolina, Virginia, Ohio and New Hampshire.

Romney scrapped plans to campaign in Virginia on Sunday, and switched his schedule for the day to Ohio. At a rally in Kissimee, Fla., he urged supporters to keep those in the storm's path "in your mind and in your hearts."

"You know how tough hurricanes can be," he told the Floridians.

Vice President Joe Biden canceled a Saturday rally in coastal Virginia Beach, Va., to allow local officials there to focus on disaster preparedness and local security concerns.

But he went ahead with an appearance in Lynchburg, which is inland. Biden said Romney and Ryan are fleeing from their record to appear more moderate than they are. They "are counting on the American people to have an overwhelming case of amnesia."

Plans for son Beau Biden, the Delaware attorney general, to join his father in Virginia were scrapped when he was called up by the National Guard to help with the storm.

Obama canceled Monday appearances in Prince William County, Virginia on Monday, and Colorado Springs, Colo., on Tuesday so he could monitor Hurricane Sandy as it moves ashore. He did move up his planned Monday departure for Florida to Sunday night to beat the storm and planned a Monday stop in Youngstown, Ohio, before returning to the White House.

En route to New Hampshire, Obama held an airborne conference call with administration officials about the federal government's role in minimizing storm damage and a ensuring speedy recovery effort.

Campaign spokesman Jennifer Psaki said the Obama team was continuing to promote early voting as something that provides flexibility for busy families, but she added that with the storm headed for shore, "safety comes first, and that's the case with early voting as well."

Romney's trip to Florida, with three events across the state, was timed to coincide with the first day of in-person early voting in a state that went for Obama four years ago and where 29 electoral votes are up for grabs this time. Both campaigns already have been working furiously to gain the advantage in the state's vote-by-mail program, an area where Republicans typically have been stronger.

"I need you to vote early!" Romney told supporters in Land O'Lakes.

Republican Rep. Paul Ryan worked his way across rainy, chilly Ohio, on a two-day bus trip, with his family in tow. At a factory in New Philadelphia, Ryan stressed the hit that manufacturing industries have taken over the last four years and promised more coal jobs, natural gas jobs and increased military spending if Romney is elected.

Speaking to more than 1,000 supporters on the factory floor at Gradall Industries, Ryan told voters: "You know it's you. You know what you have in front of you. You know your responsibility."

Campaign 2012 was serious business, with so little time left and the storm complicating the end game, but Ryan's children helped to lighten the tone. His 7-, 9- and 10-year-olds scampered between parts bins and heavy chains at the factory.

Nine-year-old Charlie waved the peace sign and mugged for cameras, prompting his mother, Janna Ryan, to shake her head and declare, "I don't know where he gets it. It's kind of crazy."

During a later stop at a bakery in Circleville, Ohio, 10-year-old daughter Liz told the bakery clerk that her dad was "sugar-free except for doughnuts and ice cream."

"And apple-fritters," Ryan agreed.

Obama, for his part, made a stop at the Common Man Merrimack, a restaurant where he toasted patrons with a Common Man Ale, saying: "To voting. To America. Doesn't matter what party."

The campaigns and their allies kept up a steady stream of TV and radio ads in the battleground states. The right-leaning Americans for Job Security made a rare purchase of Philadelphia airtime, amounting to $1.2 million, for pro-Romney ads. While a few independent groups have tried to make Pennsylvania competitive for Romney, neither Obama nor Romney has devoted ad resources to the state, which is expected to go for Obama.
