Injecting Liquid Metal Into Blood Vessels Could Help Kill Tumors 111

Posted by Unknown Lamer from the accidentally-colossus dept.
KentuckyFC (1144503) writes One of the most interesting emerging treatments for certain types of cancer aims to starve the tumor to death. The strategy involves destroying or blocking the blood vessels that supply a tumor with oxygen and nutrients. Without its lifeblood, the unwanted growth shrivels up and dies. This can be done by physically blocking the vessels with blood clots, gels, balloons, glue, nanoparticles and so on. However, these techniques have never been entirely successful because the blockages can be washed away by the blood flow and the materials do not always fill blood vessels entirely, allowing blood to flow round them. Now Chinese researchers say they've solved the problem by filling blood vessels with an indium-gallium alloy that is liquid at body temperature. They've tested the idea in the lab on mice and rabbits. Their experiments show that the alloy is relatively benign but really does fill the vessels, blocks the blood flow entirely and starves the surrounding tissue of oxygen and nutrients. The team has also identified some problems such as the possibility of blobs of metal being washed into the heart and lungs. Nevertheless, they say their approach is a promising injectable tumor treatment.

I agree. The real solution is hardened authentication getting baked right into email. I'm all for UTF8 domain names and email user names, however if the email protocol suite is going to be expanded to allow for more features, then I think security should be top of that list.

Sure, for a while, domains that span multiple character sets such as hotmail.com with a Cyrillic o could be spam flagged, however what happens when (not, if, but when) legitimate domains with multiple character sets start appearing? What about domains that use characters restricted to the intersection of two character sets such that they appear to be from one but are in fact from another?

The ONLY answer to this is an email client that can associate a certificate with a domain and checks it against received email as a matter of course. This solution not only has the property of preventing domain spoofing, but also comprehensively solves the spam problem. (It didn't get done earlier because it fell foul of the "requires everyone to agree at the same time" point on that pro forma "Why your proposal won't work" sheet.)

DNA Project 'to Make UK World Genetic Research Leader' 65

Posted by timothy from the looking-for-the-true-descendants-of-arthur dept.
mrspoonsi (2955715) writes A project aiming to revolutionise medicine by unlocking the secrets of DNA is under way in centres across England. Prime Minister David Cameron has said it "will see the UK lead the world in genetic research within years". The first genetic codes of people with cancer or rare diseases, out of a target of 100,000, have been sequenced. Experts believe it will lead to targeted therapies and could make chemotherapy "a thing of the past". Just one human genome contains more than three billion base pairs — the building blocks of DNA. Prof Jeremy Farrar, director of the Wellcome Trust, said: "I can see a future where genetics is going to come into every bit of medicine from cardiology to oncology to infectious diseases." "Twenty years from now there's going to be a plethora of those, we will have a series of mutations which academics and industry will have developed therapies for, which will be targeted at you and specific for that cancer." He said chemotherapy, which attacks all dividing cells in the body, would be replaced with such therapies. "We will look back in 20 years' time and think of blockbuster chemotherapy [as] a thing of the past and we'll think 'Gosh, what an era that was'." David Cameron has announced a series of investments across government, industry and charities totalling £300m ($500m).

Why the FCC Is Likely To Ignore Net Neutrality Comments and Listen To ISPs 140

Posted by Soulskill from the all-about-the-benjamins dept.
Jason Koebler writes: Time and time again, federal agencies like the FCC ignore what the public says it wants and side with the parties actually being regulated — the ISPs, in this case. Research and past example prove that there's not much that can be considered democratic about the public comment period or its aftermath. "Typically, there are a score or so of lengthy comments that include extensive data, analysis, and arguments. Courts require agencies to respond to comments of that type, and they sometimes persuade an agency to take an action that differs from its proposal," Richard Pierce, a George Washington University regulatory law professor said. "Those comments invariably come from companies with hundreds of millions or billions of dollars at stake or the lawyers and trade associations that represent them. Those are the only comments that have any chance of persuading an agency."
