<p>Technology really pushed humanity forward this week. IBM released findings of its latest gel invention that can attack bacteria in a completely new way. It has the potential to save lives, and even fight uncurable diseases such as HIV.</p>
<p>But did y&#8217;all see Chrissy Farr go on that OK Cupid blind date? Because that was hilarious.</p>
<p>So, maybe not all our technology favorites this week pushed the humanitarian envelope, but we&#8217;ve got some awesome stories that you&#8217;ll be sad you missed when the daily grind of a new work week starts.</p>
<p>Check them out and if we leave you wanting more, you can always hop on over to our <a href="http://venturebeat.com/tag/editors-pick/" target="_blank">Editor&#8217;s Pick</a> tag, where our top, awesomely reported stories wait for your attention.</p>
<p>Now on to this week&#8217;s cream of the crop!</p>
<h3><a href="http://venturebeat.com/2013/01/23/ibm-vastly-improves-delivery-of-nanomeds-that-kills-bacteria-where-antibiotics-fails/" target="_blank">IBM vastly improves delivery of nanomeds that kill bacteria where antibiotics fail</a></h3>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/ibm-hydrogels1.jpg" target="_blank"><img class="aligncenter size-full wp-image-611235" alt="ibm hydrogels" src="http://venturebeat.files.wordpress.com/2013/01/ibm-hydrogels1.jpg?w=655&#038;h=270" width="655" height="270" /></a></p>
<p>In 2011, IBM researchers and a research group in Singapore showed off a new kind of synthetic, biodegradable nano particle that doctors could use to attack bacteria cells that are resistant to antibiotics. Now, the same group of researchers have made the “nanomedicine” much more practical by delivering it in the form of a cream or gel that you can rub on wounds or inject into infected regions.</p>
<p>Call them nanomeds. They could save your life one day.</p>
<h3><a href="http://venturebeat.com/2013/01/22/crazy-blind-dating/" target="_blank">Why I’m dumping OkCupid’s blind dating app</a></h3>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/okcupid-blind-date-chrissy.png" target="_blank"><img class="aligncenter size-full wp-image-611237" alt="OK Cupid Blind date app" src="http://venturebeat.files.wordpress.com/2013/01/okcupid-blind-date-chrissy.png?w=655&#038;h=270" width="655" height="270" /></a></p>
<p>OkCupid CEO Sam Yagan wants to bring back a vestige of the past: the blind date. So we decided to give OkCupid’s new app, Crazy Blind Date, a whirl.VentureBeat teamed up with ABC7 News reporter Jonathan Bloom for this project: Chrissy Farr would go on an actual blind date, and the San Francisco network affiliate of ABC would interview her date on the spot. Check out how the date went.</p>
<h3><a href="http://venturebeat.com/2013/01/25/5-reasons-you-should-buy-windows-8-now/" target="_blank">5 reasons you should buy Windows 8 now</a></h3>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/windows-81.jpg" target="_blank"><img class="aligncenter size-full wp-image-611238" alt="Windows 8" src="http://venturebeat.files.wordpress.com/2013/01/windows-81.jpg?w=655&#038;h=270" width="655" height="270" /></a></p>
<p>While it’s easy to hate on Windows 8, it’s time to stop nagging about the changes and buy the upgrade before it gets way more expensive.</p>
<p>Windows 8 has sold more than 60 million licenses to date, but Microsoft has not revealed how many of these copies have been activated. Still, these are generally good numbers, and it is keeping pace with initial Windows 7 sales. Microsoft has invested a lot of time and money into Windows 8 and will continue to update the software to make it run better.</p>
<h3><a href="http://venturebeat.com/2013/01/22/new-myspace-music-licensing-problems/" target="_blank">Myspace’s newest problem: Credibility</a></h3>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/myspace1.jpg" target="_blank"><img class="aligncenter size-full wp-image-611239" alt="Myspace" src="http://venturebeat.files.wordpress.com/2013/01/myspace1.jpg?w=655&#038;h=270" width="655" height="270" /></a></p>
<p>Strapped for cash and fighting for relevance, the relaunched Myspace already has enough problems. But it looks like the company and its music-focused revamp have another, potentially bigger issue: credibility.</p>
<h3><a href="http://venturebeat.com/2013/01/22/life-after-epic-getting-to-know-cliff-bleszinski-exclusive-interview-part-one-his-past/" target="_blank">Life after Epic: Getting to know Cliff Bleszinski (exclusive interview, part one: his past)</a></h3>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/cliff-bleszinski-headshot1.jpg" target="_blank"><img class="aligncenter size-full wp-image-611241" alt="cliff bleszinski headshot" src="http://venturebeat.files.wordpress.com/2013/01/cliff-bleszinski-headshot1.jpg?w=655&#038;h=270" width="655" height="270" /></a></p>
<p>Turns out people want to hear what Cliff Bleszinski has to say. Every word. The brash and outspoken 37-year-old developer is certainly polarizing enough to warrant such attention. You might hate him for his pretty Barbie-doll wife and his two hot-rod Lamborghinis that cost more than most people’s annual salaries. You’ve probably spent more than a few hours of your life, however, totally lost in games like Unreal Tournament and Gears of War. Games that he helped create.</p>

<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=venturebeat.com&#038;blog=342986&#038;post=608375&#038;subd=venturebeat&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>
				<content:encoded><![CDATA[<p><a href="http://venturebeat.files.wordpress.com/2013/01/ibm-hydrogels.jpg" target="_blank"><img class="alignnone size-full wp-image-608804" alt="ibm hydrogels" src="http://venturebeat.files.wordpress.com/2013/01/ibm-hydrogels.jpg?w=655&#038;h=486" width="655" height="486" /></a></p>
<p>In 2011, <a href="http://www.ibm.com" target="_blank" target="_blank">IBM</a> researchers and a research group in Singapore <a href="http://venturebeat.com/2011/04/03/ibm-researchers-create-nanomedicine-to-kill-bacteria-where-antibiotics-fail/">showed off a new kind of synthetic, biodegradable nano particle</a> that doctors could use to attack bacteria cells that are resistant to antibiotics. Now, the same group of researchers have made the &#8220;nanomedicine&#8221; much more practical by delivering it in the form of a cream or gel that you can rub on wounds or inject into infected regions.</p>
<p>Call them nanomeds. They could save your life one day.</p>
<p>If this nanomedicine works as broadly as the scientists hope, it could save countless lives and protect vulnerable people such as hospital patients from illnesses that arise from bacterial infections, including staph. The medicine is based on a trick from chip manufacturing, where researchers can isolate certain kinds of cells and attack them. Too many of today&#8217;s drugs or disinfectants kill off both good cells and bad cells indiscriminately, but the synthetic polymers that IBM created can identify bacteria cells and destroy their membrane walls.</p>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/ibm-nanomeds-2.jpg" target="_blank"><img class="alignright size-full wp-image-608803" alt="ibm nanomeds 2" src="http://venturebeat.files.wordpress.com/2013/01/ibm-nanomeds-2.jpg?w=400&#038;h=315" width="400" height="315" /></a>By itself, that&#8217;s a great discovery. But today&#8217;s development builds on this. James Hedrick, an advanced organic materials scientist at IBM Research at the Almaden Research Center in San Jose, Calif., said in an interview with VentureBeat that a new antimicrobial &#8220;<a href="http://ibmhydrogels.tumblr.com/" target="_blank">hydrogel</a>&#8221; can completely eradicate drug-resistant bacteria on contact. On top of that, it forms spontaneously at body temperature and can be delivered in the form of a gelatin, such as a medicinal cream. It can also be injected into a colony of bacteria in the body and wipe it out.</p>
<p>&#8220;We think this is broadly applicable to treating all sorts of infections and diseases,&#8221; Hedrick said. &#8220;I&#8217;m thinking about things like HIV. Creating a hydrogel opens up so many more applications.&#8221;</p>
<p>The hydrogel is biodegradable, nontoxic, and biocompatible. You could, Hedrick said, put some of the gel on a tracheal tube (which is inserted down someone&#8217;s throat) or a catheter. That would vastly reduce the risk of infection related to the use of those medical devices. And that would reduce health hazards for hospital workers, visitors, and patients. It could reduce the risks of methicillin-resistant Staphylococcus aureus, known as MRSA, or staph. In 2005, staph was associated with 95,000 serious infections and 19,000 hospital-stay-related deaths in the U.S.</p>
<p>The federal Centers for Disease Control estimates that antibiotic drug resistance costs $20 billion a year in healthcare costs a year and leads to 8 million additional days spent in hospitals.</p>
<p>Today, you could spray antibacterial liquids throughout a hospital, but the bacteria could eventually become resistant as it adapts to the form of attack. The polymers can be built with a great deal of control from organic materials, which means they are biodegradable. The nano particles are physically attracted to infected cells like a magnet, breaking their membrane walls without destroying healthy cells around them. These agents prevent the bacteria from developing drug resistance by breaking through the cell wall and membrane, a fundamentally different mode of attack compared to antibiotics.</p>
<p><a href="http://venturebeat.files.wordpress.com/2013/01/ibm-nanomeds.jpg" target="_blank"><img class="size-full wp-image-608802 alignnone" alt="ibm nanomeds" src="http://venturebeat.files.wordpress.com/2013/01/ibm-nanomeds.jpg?w=655&#038;h=256" width="655" height="256" /></a>With the creation of the hydrogel, the nanomedicine could be put into antibacterial soap, deodorant, hand sanitizer, or lotion. It could help heal wounds, tuberculosis, and lung infections, Hedrick said. The nanomedicine could also target smaller problems such as toenail infections.</p>
<p>The human body&#8217;s immune systems protect us from harmful substances. But the body often rejects conventional antibiotics. But the new materials can work because they change themselves once they come into contact with water in the body or on its surface. The material self-assembles into a new polymer structure that is electrostatically attracted to the bacteria membranes (it&#8217;s like putting oil and water together). The polymers then break through the cell membranes, destroying the cell. The bacteria, which have amazing adaptive capabilities, can’t adapt to this kind of physical attack.</p>
<p>It works because cells have a natural electric charge. The polymers are drawn only to infected areas. Other antimicrobial materials aren’t biodegradable, but these new materials are made of simple organic molecules. That means they can naturally exit the body, in contrast to other medicines that gather in the body and cause side effects. That means it isn&#8217;t likely to cause skin irritation or other problems.</p>
<p>The polymers also swell into a gel form that doctors can easily manipulate. Hedrick said they can do so because of a &#8220;molecular zipper effect.&#8221; That is, the polymers interlock in the same way that zipper teeth do. When you move them around, they simply re-zip into a form that is deadly to bacteria.</p>
<p>The hydrogel has another interesting property. It can attack whole colonies of bacteria, particularly if it is injected directly into the region of an infection. These bacteria collections, known as biofilms, can be like the coatings of film on your teeth, germs on touchscreens, or growths on medical devices. The hydrogel penetrates the film and disrupts it.</p>
<p>&#8220;We can kill 100 percent of the bacteria and reduce the likelihood of a recurrence,&#8221; Hedrick said.</p>
<p>The hyrdogels are comprised of more than 90 percent water. That makes them ideal for creams, injected gelatins, or coatings for medical equipment.</p>
<p>&#8220;They tenaciously bind to water and are broad, potent antimicrobial particles,&#8221; Hedrick said.</p>
<p>IBM&#8217;s team of chemists worked with bioengineering experts at the <a href="http://www.ibn.a-star.edu.sg/" target="_blank" target="_blank">Institute of Bioengineering and Nanotechnology</a> in Singapore. The lead collaborator at the Singapore group was Yi-yan Yang.</p>
<p>Challenges remain. Hedrick said it is hard to get the polymers through the blood-brain barrier, so it is more difficult to treat diseases such as Parkinson&#8217;s disease. One group has broken off to tackle that research problem.</p>
<p>IBM is in talks with a variety of potential partners to introduce products in the cosmetic, pharmaceutical, and device coatings markets.</p>
<p>&#8220;We have a lot of exciting work under way,&#8221; Hedrick said. &#8220;We are bringing this forward as fast as possible.&#8221;</p>
<p>Michael Otto, senior investigator at the federal NIAID Laboratory of Human Bacterial Pathogenesis, is an outside expert on bacterial biofilms. He said:</p>
<blockquote><p>The significance lies first and foremost in the chemistry, allowing efficient device coating with an antimicrobial, non-toxic gel. However, as an infectious disease specialist/microbiologist, I must say that the categorical problem with antimicrobial coatings is whether they work &#8216;in vivo.&#8217; Previously, antimicrobial coatings have not shown much effect in vivo. Notably, the authors did not investigate in-vivo effects in animal models, which would be a must to tell whether there is promise for application and prevention of biofilm-associated device infections in humans.</p>
<p>The main problem encountered in an in-vivo setting is that human protein material coats the device; and then it has often been seen that the bacteria don’t have much of a problem growing on it – with antimicrobial coating or not. Also, the authors only show “biofilm dispersion” with one layer of bacteria in their control. Probably only the bacteria next to the coated device are being reached by the antimicrobial activity (given its mechanism), so additional layers may again grown without much of a problem.</p>
<p>Bottom line: without in-vivo investigation, one can’t tell whether this is a major advance for potential treatment/prevention. Frankly, before making such a hype of the finding, this should have been done and one wonders why it hasn&#8217;t. Also, when you judge the authors’ press release of how significant the finding is, note that this is company research.</p></blockquote>

				<content:encoded><![CDATA[<p><img class="alignnone size-full wp-image-252305" title="ibm nano" src="http://venturebeat.files.wordpress.com/2011/04/ibm-nano.jpg?w=630&#038;h=467" alt="" width="630" height="467" /></p>
<p><a href="http://www.ibm.com" target="_blank">IBM</a> and a research group in Singapore have engineered a new kind of synthetic, biodegradable nano particle that could be used to attack bacteria that have become resistant to antibiotics.</p>
<p>The researchers believe that the nanomedicine breakthrough could eventually be used to fight infectious diseases better than antibiotics. If it works, the nanomedicine could save countless lives and protect people from illnesses that arise from bacterial infections, like staph.</p>
<p>Using a trick from chip manufacturing, the researchers figured out how to isolate certain kinds of cells and attack them. That gets around the problem of many drugs today that kill off the good red blood cells at the same time that they eradicate bad cells. The researchers said the synthetic polymers they created can seek out bacteria cells and destroy their membrane walls.</p>
<p>&#8220;<img class="alignright size-full wp-image-252306" title="ibm nano 2" src="http://venturebeat.files.wordpress.com/2011/04/ibm-nano-2.jpg?w=400&#038;h=236" alt="" width="400" height="236" />It&#8217;s like a hammer,&#8221; said James Hedrick, advanced organic materials scientist at IBM&#8217;s Almaden research center in San Jose, Calif. &#8220;We target the membrane directly. The overall goal is to have a huge societal impact, with improved ways for drug and gene delivery.&#8221;</p>
<p>Hedrick, who has worked at IBM for a couple of decades, said his team and another at the <a href="http://www.ibn.a-star.edu.sg/" target="_blank">Institute of Bioengineering and Nanotechnology</a> in Singapore brought in different approaches. IBM had done work on nanotechnology and semiconductor manufacturing while the Singapore institute worked the medicine.</p>
<p>They created new types of polymers that could detect and destroy bacteria and infectious diseases like Methicillin-resistant Staphylococcus aureus, known as MRSA, or staph. Hedrick said the polymers can be built with a great deal of control from organic molecules, which makes them biodegradable.</p>
<p>The nano particles are physically attracted to infected cells like a magnet, breaking their membrane walls without destroying healthy cells around them. These agents prevent the bacteria from developing drug resistance by breaking through the cell wall and membrane, a fundamentally different mode of attack compared to antibiotics.</p>
<p>MRSA is a type of dangerous bacteria that is commonly found on the skin and easily contracted in places like gyms, schools and hospitals where people are in close contact. In 2005, MRSA was responsible for nearly 95,000 serious infections, and associated with almost 19,000 hospital stay-related deaths in the United States.</p>
<p>Hedrick said that decades of learning about chip materials has helped the team, which has worked on the problem at least five years, to figure out how to craft nano structures that can be injected directly into the body or applied to the skin. The nanomedicine could, for instance, be put into anti-bacterial soap, deodorant, hand sanitizer or lotion. It could help heal wounds, tuberculosis, and lung infections.</p>
<p>Our immune systems are designed to protect us from harmful substances, both inside and out, but conventional antibiotics are often rejected by the body or have a limited success rate in treating drug-resistant bacteria. But the new materials can work because they change themselves once they come into contact with water in the body or on its surface. The material self-assembles into a new polymer structure that is electrostatically attracted to the bacteria membranes. The polymers then break through the cell membranes, destroying the cell. The bacteria can&#8217;t adapt to this kind of physical attack.</p>
<p>Fortunately, cells have a natural electric charge. The polymers are drawn only to infected areas. Other antimicrobial materials aren&#8217;t biodegradable, but these new materials are made of simple organic molecules. That means they can naturally exit the body, in contrast to other medicines that gather in the body and cause side effects.</p>
<p>The lead collaborator at the Singapore group was Yiyan Yang. The new polymers were tested against clinical microbial samples at a medical hospital at Zhejiang University in China. Clinical trials and plenty of other work have to be done before the nanomedicine will be commercially available.</p>
<p>&#8220;It&#8217;s still a work in progress and is in the early stages,&#8221; Hedrick said. &#8220;The results are extraordinarily promising at this stage.&#8221;</p>
