Evolution of Dropbox’s Edge Network

Since launching Magic Pocket last year, we’ve been storing and serving more than 90 percent of our users’ data on our own custom-built infrastructure, which has helped us to be more efficient and improved performance for our users globally. But with about 75 percent of our users located outside of the United States, moving onto our own custom-built data center was just the first step in realizing these benefits. As our data centers grew, the rest of our network also…

Re-Architecting Cash and Digital Wallet Payments for India with Uber Engineering

Tracking methane with robust laser technology

The LiDAR system for the MERLIN mission incorporates all components from the pump laser to the frequency conversion in a particularly compact design suitable for space operation. Credit: Fraunhofer ILT, Aachen Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute…

How drones are advancing scientific research

Credit: Richard Unten Drones, or unmanned aerial vehicles (UAVs), have been around since the early 1900s. Originally used for military operations, they became more widely used after about 2010 when electronic technology got smaller, cheaper and more efficient, prices on cameras and sensors dropped, and battery power improved. Where once scientists could only observe earth from above by using manned aircraft or satellites, today they are expanding, developing and refining their research thanks to drones. Drones can range from the…

Engineering Ethics Blog: The Grenfell Tower Tragedy

In 1974, a new high-rise public housing apartment building opened in West London.  Called Grenfell Tower, it was 24 stories tall and designed to house as many as 600 people in 120 apartments.  Photographs of it taken before a renovation in 2015 show large windows on one side and smaller ones on the adjacent side.  In 2014, as reported in this blog, the 63-story Address Hotel in Dubai, United Arab Emirates went up in flames as aluminum-clad foam-plastic panels called…

World’s largest randomized controlled trial of acupuncture in emergency departments finds it is a safe and effective alternative to pain-relieving drugs — ScienceDaily

The world’s largest randomized controlled trial of the use of acupuncture in emergency departments has found the treatment is a safe and effective alternative to pain-relieving drugs for some patients. Led by RMIT University in Melbourne, Australia, the study found acupuncture was as effective as pain medicine in providing long-term relief for patients who came to emergency in considerable pain. But the trial, conducted in the emergency departments of four Melbourne hospitals, showed pain management remains a critical issue, with…

Technology Insight Report: Carbon Nanotubes in Energy Storage Devices

Carbon Nanotubes with their extraordinary properties in terms of strength, thermal and electrical properties are poised to have a big impact on the future of material sciences, electronics and nanotechnology. Owing to their specialized structures and minute diameter, they can be utilized in the creation of ultra-thin energy storage devices which in today’s world where electronics is getting smaller could redefine the electronics market and replace capacitors and batteries they way we see them now. Research and development around carbon…
