Producing simple kits for safe water in Rajasthan

University of Adelaide researchers are planning to produce simple, low-cost, self-assembly water purification kits to provide fresh drinking water in the Indian state of Rajasthan, South Australia’s sister state. The kits make use of sunlight and gravity, some clever design and basic materials to produce up to 10 litres/day of safe drinking water. The University today launched its first official crowdfunding project to fund the research, which will be needed to design and produce the kits. The University aims…

WHOIS going to be at the Grace Hopper Celebration?

Ubuntu us are doing the round trip! It’s time to live – WAN you arrive at GHC, come meet us and say HELO (we love GNU faces, we’ll be very api to meet you). When you’re exhausted like IPv4, git over to the Cloudflare corner to reboot –– we’ll have chargers and Wi-Fi (it’s not a SYN to REST). R booth can be your ESC. Then Thursday morning we’re hosting a breakfast bash with Zendesk –– it will be quite…

It’s not a vacation cruise.…

Technology increases the sensitivity of infrastructural sensors by more than 50 times

Technology from the Public University of Navarre monitors the structural health of infrastructure (bridges, viaducts, oil pipelines, gas pipelines, etc.) and can be used in intensity-based optical sensors that modify the amount of light in the system in the presence of physical as well as chemical changes, as explained in Sergio Rota’s Ph.D. thesis read at the Public University of Navarre (NUP/UPNA). “Ever since fibre optics burst onto the scene in telecommunications, many developments based on its properties have emerged,”…

Painless microneedles extract fluid for wearable sensors for soldiers, athletes

Sandia National Laboratories materials scientist Ronen Polsky positions a prototype 3-D-printed microneedle holder on the arm of Sandia science writer Mollie Rappe. Rappe participated in a clinical trial to see the best length of needle to extract the interstitial fluid on the path to track the physiological condition of soldiers. Credit: Randy Montoya The lab is calm and quiet, clean and well organized; boxes of tiny needles and sample tubes are neatly stacked above a pristine paper-covered countertop. This is…

Wearable device that tracks indoor and outdoor air quality

MIT-France student intern Annie Dai (seated) says of her summer at Plume Labs: “This was probably the best summer I’ve had in my life and I think that was partially because it’s the most responsibility I’ve been given on a project.” Credit: Lillie Paquette/School of Engineering This past June, Grace Li ’17 stepped off a plane in Paris ready to spend her summer tracking down a silent killer. Now Li, her former teammates, and the flock of trained pigeons who…

Higher processor performance with microchannel cooler

The integration of microchannels into the silicon interposer allows for the first time to cool a processor also from the bottom and thereby increase the computing power. Credit: Fraunhofer IZM One of the limiting factors for the computing power of processors is the operating temperature. As part of the CarriCool project under the aegis of IBM, Fraunhofer researchers have developed a new, effective cooling method: By integrating microchannels into the silicon interposer it is for the first time possible to…

Detecting impurities on 3-D components

The fluorescence scanner – an imaging, inline measuring system – inspects components for impurities during the manufacturing process and identifies the exact point of contamination. Credit: © Photo Fraunhofer IPM Impurities adhering to the surface of components can cause problems in later stages of the production process – or even make the entire component useless. A new fluorescence scanner developed by the Fraunhofer Institute for Physical Measurement Techniques IPM allows specialists to inspect metallic parts for residues of grease, machining…

Drones controlled with brain-computer interface

Credit: Deanna Dent/ASU Now Single unmanned autonomous vehicles (UAVs) directed by joysticks, radio controllers, and mobile phones are already accomplishing a variety of useful tasks, such as aerial photography and security patrols. But using multiple drones requires multiple human operators, and this presents a coordination problem. Now a single operator using emerging…

Internet Security Isn’t Child’s Play

Full disclosure:  my wife and I have never had children.  The closest we have come to full-time responsibility for someone younger than 80 was when our ten-year-old nephew came to stay with us for part of the summer of 2013.  So what I have to say about the hazards of buying smart Internet-connected toys for your kids is, from my point of view, entirely hypothetical and untouched by the seasoning of personal experience.  Nevertheless, it’s a new kind of problem…
