Technology Researchers use nanorobots to kill tumors in mice
Cellphone radiation poses no real harm to humans, new research says
Male rats showed a small increase in a kind of heart tumor after exposure to massive amounts of cellphone radiation, a new government study reports. There’s an ongoing debate about whether cellphones can give you cancer — especially brain cancer, since our phones spend so much time near our faces. It’s true that cell phones do emit radiation. But it’s radiofrequency radiation, which is much lower energy than the ionizing radiation you’d get from an X-ray, or, say, nuclear fallout. Ionizing radiation can cause DNA damage that can eventually lead to cancer. But the radiofrequency radiation from a cellphone doesn’t work that way — and today’s results support that.
Our current methods of fighting malignant tumors are wildly inadequate. Chemotherapy and radiation treatments, while sometimes successful, come with massive side effects, mainly because every other cell in the body is also getting bombarded with chemicals and radiation even though the main targets are the tumor cells. Finding a way to while leaving healthy cells alone is something that many researchers are working towards and a out today demonstrates that nanorobots made out of DNA could be an effective option.
The research team took DNA from a virus and turned it into a sort of DNA sheet. That sheet was then loaded with an enzyme called thrombin -- a chemical that can clot blood -- and the sheet was then rolled into a tube, with the thrombin kept protected inside. To the ends of that DNA tube, the researchers attached small bits of DNA that specifically bind to a molecule found in tumor cells, and they served as a kind of guide for the. The idea is that once the nanorobots are introduced into an organism, they'll travel around and when those guiding bits of DNA come into contact with those tumor-associated molecules, they'll attach. Then, the DNA tube will open up, exposing the thrombin within. That thrombin will then clot the blood supply to the tumor, effectively cutting off its nutrients and ultimately killing it.
Hackers infect Android phones, TVs to mine cryptocurrency
Chinese researchers found hackers turning internet-connected devices into tools for creating caches of the digital currency Monero.The attack affected 7,000 devices in China, which were hacked into a network that harnessed the processing power of the connected devices to mine, or digitally create, the Monero cryptocurrency, according to ZDNet. Though not as big as some recent botnets, security experts say this approach will increasingly be used by hackers looking to make money off of other people's computers, IoT devices, phones and tablets.
To test their nanorobots, the researchers injected them into mice infected with human breast cancer cells and human ovarian cancer cells as well as mouse models of human melanoma and lung cancer. In each case, the nanorobots extended the life of the mice and slowed or reversed tumor growth. Further, in the case of the melanoma model, the nanorobots appeared to be able to prevent the spread of melanoma to the liver and with the lung cancer model, the lungs even showed an ability to begin repairing themselves once the tumor growth had slowed.
Of course, the ability to treat tumors would be moot if the nanorobots themselves posed a risk to people. But the team showed that the bots didn't clot blood outside of the tumors and they didn't trigger any significant immune responses in either mice or pigs.

In 2006 Interview, Fergie Revealed Quentin Tarantino Bit Her During ‘Grindhouse’ ShootThe Jezebel website has unearthed a 2007 interview with Fergie, who appeared in Robert Rodriguez's contribution to "Grindhouse", which also featured a standalone story directed by Tarantino.
While they're still experimental and haven't been tested in humans, these nanorobots show a lot of promise for treating cancer. "Our research shows that DNA-based nanocarriers have been shown to be an effective and safe cancer therapy," Guangjun Nie, one of the researchers on the project, said in a statement. "We are currently working with a biotech firm to translate this revolutionary technology into a viable anti-tumor therapeutic."
