You can now use Apple Pay to donate to 22 UK charities
Apple has partnered with 22 UK charities to let iOS users pledge donations using Apple Pay. The feature, which rolled out in the US last November, operates inside the Safari browser and lets anyone with a supported iPhone, iPad or Apple Watch securely send money to their favourite organisation using only their fingerprint.
Wind tunnel PC case pushes the air cooling envelope, does its thing for cancer research
Pushing air cooling to its limits might mean buying a bigger fan to the mortal PC builder, but for Mike at Total Geekdom, it meant constructing a wind tunnel case. Built from a box fan, medium-density fiberboard, lexan and aluminum, the tunnel increases airspeed by about 240 percent and cools its contents with a brisk 9 mph breeze. At full bore, however, the fan churns out air speeds between 26 and 30 mph inside the case's sweet spot. As for computer hardware, the rig packs an Ivy Bridge 3770K processor, a pair of Radeon 7970 (Sapphire Dual-X) GPUs, 8GB of RAM and a 40GB SSD. There's still room to overclock the beast, but it currently keeps its CPU humming at 4.5GHz with temperatures between 64 and 65 degrees Celsius, and can run its GPUs at 1225MHz with core temperatures at 46 and 56 degrees Celsius. So, what does one do with a wind tunnel-cooled PC? Why donate time and computing processes for cancer research through the World Community Grid project, of course.

Jellyfish-mimicking device could snatch cancer cells right out of the bloodstream
If you think the picture above looks like droplets of blood being snared in a sticky tentacle, then you have a scarily active -- but in this case accurate -- imagination. It's actually a microfluidic chip that's been coated with long strands of DNA, which dangle down into the bloodstream and bind to any cancerous proteins floating past -- directly imitating the way a jellyfish scoops up grub in the ocean. If required, the chip can release these cells unharmed for later inspection. According to the chip's designers at Boston's Brigham and Women's Hospital, the catch-and-release mechanism can be put to both diagnostic and therapeutic use in the fight against Big C, and can also be used to isolate good things, like fetal cells. The next step will be to test the device on humans -- at which point we may owe an even greater debt of gratitude to our gelatinous friends. [Image credit: Rohit Karnik and Suman Bose]
New high-res imaging could make biopsies obsolete, doctors still cutting up in meantime
So maybe a true-to-life Innerspace is still a few years off, but a professor at the University of Rochester has developed a way to take high-resolution 3D images under the skin's surface, potentially eliminating the need for biopsies in cancer detection. Professor Jannick Rolland created a prototype that uses a liquid lens, in which a droplet of water replaces the standard glass lens, in conjunction with near-infrared light, to take thousands of pictures at varying depths. Those images are then combined to create clear, 3D renderings of what lies up to one millimeter below your epidermis. The method has already been tested on livings beings, but is likely a long way from making it to your doctor's office, which means it's off to the guillotine for that Pangaea-shaped mole you've been picking at.
Robot doctors join the fight against breast cancer
From Da Vinci robosurgeons to helpful nursebots , robots are becoming commonplace in hospitals the world over -- and now researchers at Duke University have developed a rudimentary tabletop robot that uses 3D ultrasound technology to detect a 'lesion' in a simulated sponge breast, pinpoint its exact location, and perform a biopsy. All the calculations are performed by the device itself, using what has been described as "a basic artificial intelligence program." The next step in the research will be an upgrade that will that the robotic arm from three-axis to six-axis capability, and a change from the old sponge-based simulated breast to one made from turkey breasts, which approximates the density of human breast tissue. According to Stephen Smith, director of the Duke University Ultrasound Transducer Group, if things stay on track, robots will be performing routine breast exams and biopsies in five to ten years.
