The antibiotic cocktail produced by symbiotic bacteria changed very little in the course of evolution and its antipathogenic effect remained unaltered — ScienceDaily

The discovery of penicillin about 90 years ago and the widespread introduction of antibiotics to combat infectious diseases have revolutionized human medicine. However, in recent decades, the increase in multidrug-resistant pathogens has confronted modern medicine with massive problems. Insects have their own antibiotics, which provide natural protection against germs. A team of scientists from the Johannes Gutenberg University in Mainz and the Max Planck Institute for Chemical Ecology in Jena have now found that beewolves, unlike humans, do not face…

Chrome’s plan to label sites as “Not Secure”

Google just announced that beginning in July 2018, with the release of Chrome 68, web pages loaded without HTTPS will be marked as “not secure”. More than half of web visitors will soon see this warning when browsing unencrypted HTTP sites, according to data from Cloudflare’s edge that shows 56.62% of desktop requests originate from Chrome. Users presented with this warning will be less likely to interact with these sites or trust their content, so it’s imperative that site operators…

New technology combines LEGO bricks and drones

From February 15 to 18, children and families visiting the LEGO World expo in Copenhagen, Denmark will have the chance to make their brick-building dreams take flight with a flock of interactive miniature drones developed by the Human Media Lab at Queen’s University in Canada in collaboration with the LEGO Group’s Creative Play Lab. The system allows children to arrange LEGO elements into a shape of their choice and watch as a group of miniature drones takes flight to mimic…

Thermal blankets melt snow quickly

Credit: CC0 Public Domain Removing snow piled high in parking lots and along roadsides could soon be a far less tedious task. In a study appearing in ACS’ journal Langmuir, scientists report that they have tested sunlight-absorbing thermal blankets capable of melting snow three times faster than it would on its own. They say the blankets could slash snow-removal costs and reduce the risk of environmental contamination caused by soot and other products used to melt the white stuff. Fresh…

Implementing Model-Agnosticism in Uber’s Real-Time Anomaly Detection Platform

Real-time alerting and monitoring systems contribute to our goal of achieving 24/7 reliability. To further this mission, Uber Engineering built an anomaly detection platform to find and flag deviations in system metrics and notify the on-call engineers responsible for addressing them. Our platform was built to support a single forecasting model, but our growth necessitated new ones, each with their own distinct timeframes. Rather than starting from scratch for each new design, we opted to make our existing platform model-agnostic.…

How we built rearranging Pins – Pinterest Engineering – Medium

Samuel Hsiung & Alice Chang | Pinterest engineers, Emerging products Listening to user feedback is essential to building a product Pinners love and use to discover and save ideas every day. Often, their feature requests present interesting technical challenges for our engineers. For example, today we launched the ability to reorder Pins on boards, one of the most frequently asked for features. As we set out to build its backend service, we tackled new database scaling problems we’ll cover in…
