Filming how our immune system kill bacteria

Posted by in categories: biotech/medical, nanotechnology

To kill bacteria in the blood, our immune system relies on nanomachines that can open deadly holes in their targets. UCL scientists have now filmed these nanomachines in action, discovering a key bottleneck in the process which helps to protect our own cells.

The research, published in Nature Communications, provides us with a better understanding of how the kills bacteria and why our own cells remain intact. This may guide the development of new therapies that harness the immune system against bacterial infections, and strategies that repurpose the immune system to act against other rogue cells in the body.

In earlier research, the scientists imaged the hallmarks of attack in live bacteria, showing that the immune system response results in ‘bullet holes’ spread across the cell envelopes of bacteria. The holes are incredibly small with a diameter of just 10 nanometres.

The Much-Hyped, 18,000mAh Energizer Phone Flopped on Indiegogo

Posted by in categories: computing, mobile phones

Mobile World Congress this past February included the unveiling of several notable smartphones like the Nokia 9 PureView and LG G8. However, one device got an inordinate amount of attention — the Energizer Power Max P18K Pop. Hiding behind that clunky name was a phone with a gigantic 18,000 mAh battery. This brick of a phone ended up on Indiegogo, and despite all the hype, it flopped. Hard. Of the anticipated $1.2 million, the phone only pulled in pre-orders worth $15,005 — just 1 percent of the required funding.

The Energizer Power Max P18K Pop is not actually a product of the battery manufacturer. The Energizer name is merely licensed by Avenir Telecom, a French manufacturer of phones, cables, and other accessories. It has produced other Energizer phones in the past, but none of them sparked the same combination of fascination and amusement.

The biggest comparison of sci-fi spaceships ever is complete at last

Posted by in categories: military, space travel

At last, it’s done. The biggest spaceship size chart ever created is now complete and fully operational. 4,268 × 5,690 pixels of technological terror that includes everything from the smaller Star War ships to EVE. According to its author, Dirk Loechel, this is the last update. It’s epic.

The last update

For real this time: This is the final major content update, though if there are issues I’ll still fix them. I also haven’t forgotten I wanted to vectorize the writing. It’s still on the radar. But content-wise, I think that is about all I can put in.

MIT Cryptographers Are No Match For A Determined Belgian

Posted by in categories: robotics/AI, supercomputing

Twenty years ago, a cryptographic puzzle was included in the construction of a building on the MIT campus. The structure that houses what is now MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) includes a time capsule designed by the building’s architect, [Frank Gehry]. It contains artifacts related to the history of computing, and was meant to be opened whenever someone solved a cryptographic puzzle, or after 35 years had elapsed.

The puzzle was not expected to be solved early, but [Bernard Fabrot], a developer in Belgium, has managed it using not a supercomputer but a run-of-the-mill Intel i7 processor. The capsule will be opened later in May.

The famous cryptographer, [Ronald Rivest], put together what we now know is a deceptively simple challenge. It involves a successive squaring operation, and since it is inherently sequential there is no possibility of using parallel computing techniques to take any shortcuts. [Fabrot] used the GNU Multiple Precision Arithmetic Library in his code, and took over 3 years of computing time to solve it. Meanwhile another team is using an FPGA and are expecting a solution in months, though have been pipped to the post by the Belgian.
