Le meilleur du Web: 'Humans of New York'
Screen Shot 2015-02-23 at 20.11.07.png

Depuis 20 ans que je suis l’actualité Internet et les "success stories" qui en découlent, 'Humans of New York', est pour moi la meilleure histoire que j'ai jamais entendue. C'est la réussite de quelqu’un de talentueux, qui à force de patience et de persévérance a réalisé son rêve, sans investissement hormis sa caméra et sa tenacité, et qui a atteint le sommet de la reconnaissance grâce à la portée du Web et des réseaux sociaux.

C'est le sujet de mon billet ce matin dans Bilan.

15-minute HIV and Syphilis tests thanks to a dongle attached to your smartphone

Columbia University biomedical engineering researchers have developed new 15-minute HIV and Syphilis tests that work by hooking a plastic dongle into your smartphone. The smartphone dongle enables a “plug-and-play” operation for the user. The Washington Post reports.

quotemarksright.jpgYou simply insert a pinprick of blood onto a disposable plastic collector, connect the plastic collector to a microfluidic chip used to analyze the sample and insert the chip with the blood sample into the dongle. Once you’ve logged into an app, your smartphone can start to determine the presence of HIV or syphilis in your blood and display the results on your smartphone’s screen 15 minutes later.

More than its ease of use, the cost factor of the dongle is what makes it possible to speculate that this type of smartphone diagnostics could one day lead to a new direct-to-consumer model for health care. The equipment needed to perform a laboratory-quality HIV test can cost upwards of $18,450 apiece. Contrast that to the cost of a cheap plastic dongle, which costs an estimated $34 to make. That makes it possible to imagine a future where tests are faster, simpler and cheaper than anything available today.quotesmarksleft.jpg

Amazon Files Patent for Mobile 3D Printing Delivery Trucks
p24.pngLate last week United States Patent and Trademark Office published a patent filing by Amazon Technologies, Inc. which outlines a method of 3D printing on-demand within mobile manufacturing hubs. According to Amazon, such a setup could save the company time and money on several fronts. 3DPrint.com reports.

quotemarksright.jpgBy utilizing ‘mobile manufacturing apparatuses Amazon would be able to send an STL file to a mobile unit that’s closest to a customer, providing it with instructions to print out an item which was ordered. When the item has been completed, it could then be within miles of the customer who ordered it and quickly delivered or picked up.

The mobile hubs, according to the patent filing, would include a means to both additively and subtractively manufacture an item. This could include a number of different 3D printing technologies as well as CNC machining tools, which would ultimately reduce Amazon’s reliance on warehouse space as well as the robots and employees needed to sort through these stored items.quotesmarksleft.jpg

The Good Drone

Can 'flying donkey' drones plug Africa's transport gap?
imgres.jpg Africa is growing economically and needs better transport links. So what's the answer? Could it be cargo drones - or "flying donkeys" as one Kenyan farmer put it? The BBC reports.

quotemarksright.jpgAfrotech, a technology innovation project set up by the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland, certainly thinks so.

Director Jonathan Ledgard, a former foreign correspondent in Africa, thinks they will enable the continent to leapfrog traditional infrastructure development and grow faster economically.

Next year, through its spin-off company Red/Blue, Afrotech will begin testing cargo drones capable of carrying small packages across distances of up to 80km (50 miles).

The first route will be a "red line" flying units of blood to remote health clinics.quotesmarksleft.jpg
