Robot surgeon uses frighteningly large needle to remove shrapnel, your resistance
by Tim Stevens posted Jun 22nd 2009 at 9:41AM
We've reported on many a creepy looking and dangerous sounding robot in the past, but this one might just take the cake when it comes to dominating your nightmares for the next few nights. Developed by a team at Duke University, the bot uses ultrasound to identify areas of density in human flesh, then starts probing them with a rather painfully large looking needle. It could be used to locate and extract bits of shrapnel from stricken GIs on the battlefield, but that same tech might also be deployed to pierce women's breasts and men's prostates -- ostensibly to treat cancers of those respective regions, but we can think of more nefarious reasons. The bot doesn't have a name, but once it and its kind take over, neither will you. [Via gizmag]
NASA's new e-nose can detect scent of cancerous brain cells
by Ross Miller posted May 2nd 2009 at 11:41AM
NASA's recently developed electronic nose, intended for air quality monitoring on Space Shuttle Endeavour and later the International Space Station, has a rather fortunate and unintended secondary role. In addition to being able to detect contaminants within about one to 10,000 parts per million, scientists have discovered it can also sniff out the difference in odor between normal and cancerous brain cells -- not a new use for e-noses, but certainly one that helps to advance the field. Groups such the as Brain Mapping Foundation, City of Hope Cancer Center, and Jet Propulsion Laboratory have been testing the technology and hope it one day leads to a new understanding of cancer development. We'd also wager it can accurately detect what cologne or perfume you're wearing, another unintended side effect and probably not as fun of a party trick as it seems.[Via Slashdot; image courtesy of RSC]

Lumicure claims to be making progress in using OLEDs to treat skin cancer
by Donald Melanson posted Dec 19th 2008 at 2:54PM
The folks at Lumicure have been talking up OLEDs as a potential tool to treat skin cancer for a few years now and, while they still don't exactly have a whole lot to show for themselves, they're now claiming that they're making "excellent progress," and that they actually hope to have a product on the market by the fourth quarter of 2009. That progress is apparently due in large part to the $5 million in funding they received earlier this year although, again, they don't seem to be saying how that money is being put to use. The basic technology, first shown off more than two years ago, consists of a band-aid-type device that's connected to a battery, which lets the patient wear the device all day long, and is apparently more cost-effective and less painful than other methods of treatment. Apparently, the company is so pleased with its progress that it's already starting to focus on its next target: acne.[Via OLED-Info.com, image courtesy LEDs Magazine]

Philips aims to reduce cancer treatment side effects with drug-loaded microbubbles
by Donald Melanson posted Oct 6th 2008 at 5:26PM
It may not be quite as attention-grabbing as lasers or nano explosives, but Philips Research seems to think that it's so-called microbubbles could have a big impact on cancer treatment nonetheless, and they're apparently already showing some promise. According to the company, the red-blood-cell-sized bubbles would be used to carry drugs through the patients bloodstream and tracked using ultrasound imaging. Then, once they've reached their target, a focused ultrasound pulse would rupture the bubbles and release their drug payload. That, Philips says, would not only increase the effectiveness of the drugs, but reduce the side effects normally associated with them and, ultimately, lead to a quicker recovery. From the looks of it, however, things are still at the pre-clinical stage, and there's no indication of any future plans just yet.
French doctors use laser to destroy brain tumor in conscious patient
by Nilay Patel posted Aug 30th 2008 at 3:12PM
Neurosurgery with robotic assistance is getting pretty old hat nowadays, so it looks like scientists are trying to up the difficulty factor by keeping their patients awake -- a team of French doctors just completed the first successful removal of malignant brain tumor from a still-conscious patient, using a computerized laser and an MRI scanner to guide the probe. The fiber-optic laser was fed into the brain through a 3mm (.12 inch) hole in the patient's skull and guided via MRI to the tumor, where it fired for two minutes and completely destroyed the cancerous tissue. Once the tumor cells were dead, the cable was removed and the patient was allowed to return home -- all within a single day. That's pretty impressive, and it comes on the heels of 15 similar trials where five out six patients who underwent the total removal procedure were cancer-free nine months after surgery. The team says further research will cost an additional two million euros to progress, but if this technique works as well as they claim after peer review, we'd guess that money won't be hard to come by.[Via Fark]
Researchers aim to detect skin cancer via scent
by Darren Murph posted Aug 22nd 2008 at 2:58PM
Here's an interesting one. A group of US experts have discovered that a common form of skin cancer could one day be detected very early on by simply analyzing scents. More specifically, it was found that basal cell carcinomas give off an odor that is distinctly different than samples from healthy skin, which obviously opens up the possibility for "cheap and painless testing." In the future, researchers are hoping to create scent profiles for other types of skin cancer, including the infamous malignant melanoma. Believe it or not, a machine may be only one of the devices used to eventually sniff cancerous cells -- similar research is ongoing using canines and their remarkably sensitives schnozes.Colorizing technology highlights cancerous tissue
by Darren Murph posted Aug 20th 2008 at 10:23PM
In operating rooms today, cancer surgeons are essentially forced to operate without any definitive way of determining whether or not 100% of the diseased tissue has been removed. Thanks to a radical invention by researchers in Massachusetts, that huge limitation could soon be a thing of the past. A new system, dubbed FLARE (Fluorescence-Assisted Resection and Exploration), involves a near-infrared (NIR) imaging system, a video monitor, and a computer. These tools are used to see special chemical dies (christened NIR fluorophores) that are crafted to "target specific structures such as cancer cells when injected into patients." When these dyes are exposed to NIR light, the cancer cells light up, giving doctors an easy look at what they have left to remove. The team is gearing up to showcase the technology at the American Chemical Society national meeting in Philadelphia -- here's hoping it can be put to good use in the very near future.3D mammograms increase breast cancer detection by 23 percent

Silicon wafer directs and filters out cancer cells
by Joshua Fruhlinger posted Jun 8th 2008 at 10:16AM
Normally we get excited when a slab of silicon makes our games run at 60 frames per-second, but in this case we're impressed with a new chip that filters out cancer cells. The device, created by some impressive souls at Princeton and Boston University, directs and focuses streams of cells in a liquid. Like a change sorter, it then separates regular cells form unusual ones. The silicon wafer is tacked with tiny pillars that catch abnormal cells that are, in the end, potentially cancerous. The device hasn't been used to any major extent, but we'll keep an eye on this promising discovery.Carbon nanotubes causing asbestos-like effects in lab mice
by Nilay Patel posted May 21st 2008 at 5:09AM
The scientific and engineering possibilities of carbon nanotubes are hard to overestimate, but a study out of the UK might put a damper on the small-scale party for a while: mice injected with certain lengths of nanotubes developed lung problems similar to those caused by asbestos. Apparently the long, straight shape of the nanotubes causes problems for the lining of the lungs designed to deal with particulate matter, which can cause scarring, inflammation, and "probably cancer in the long term." That's a big "probably," however -- researchers say they're a long way from actually proving the link between long nanotubes and cancer, but no one's denying that it's troublesome, including the Nanotechnology Industries Association, which told the BBC that "there could be reason for concern... but it needs to be validated." It also seems like the focus is on handling the tech correctly, which is promising -- we'll keep an eye on how this plays out.[Thanks, TC]

Cancer patient has PSP stolen en route to chemotherapy treatment
by Darren Murph posted Mar 30th 2008 at 9:00AM
There's depressing gaming stories, and then there are outright travesties. Unfortunately, this case falls squarely into the latter category, as a 7-year old cancer patient had his beloved PlayStation Portable swiped -- right along with his medical records, a backpack full of medication, his games and even his homework -- while en route to a chemotherapy treatment for a tumor in his brain. Apparently the boy's family had stopped at a restaurant while traveling from Oklahoma to Texas, and while inside, thieves had their way with what was left inside the vehicle. Thankfully, authorities from the Dallas police department came to the rescue by purchasing a brand new PSP and raising over $1,000 to repurchase the goods that were lost, and as for the crooks, we'll just trust karma to handle the rest.[Via PSPFanboy, image courtesy of Flickr]
