MS Recalls Some Surface Pro Power Cables; Nanoparticles May be Able to Kill Antibiotic-Resistant Bacteria

Microsoft is recalling some Surface Pro power cables. ZDnet.com says they have overheating concerns. The cords are apparently wound too tightly, and as they are twisted or pinched over time, a small number of people have reported the heat issue. The recall does not affect the Surface Pro 4, or non Surface Pro models. If you have a Surface Pro, Pro 2, or Pro 3 bought before March 2015, you should be getting a new power cord.

Researchers at University of Colorado Boulder have found that light activated therapeutic nanoparticles may one day be used to kill antibiotic-resistant bacteria. According to bgr.com, the so-called ‘quantum dots,’ 20,000 times smaller than a human hair, can act directly on the infection without affecting the healthy tissue around it. The key these researchers have discovered is to taylor the dots to specific infections by activating the tiny particles with certain light wavelengths. Previously, the quantum dots had been known to kill bacteria, but also damaged the tissue around the area. In tests, the light activated ones killed 92% of the drug resistant bacteria! If perfected, the treatment could also be effective therapy for HIV and cancer.
