Importance of studying sleep and eating in tandem — ScienceDaily

A new study from scientists on the Florida campus of The Scripps Research Institute (TSRI) offers important insights into possible links between sleep and hunger — and the benefits of studying the two in tandem. A related paper from the same lab is providing researchers an accessible tool for pursuing further investigations involving multiple fruit fly behaviors. While many humans enjoy a daily caffeine fix, scientists have found that caffeine repels Drosophila melanogaster — a species of fruit fly often…

Deterring drones from ballparks and botanical gardens

Duke Gardens to develop a set of affordable and aesthetic guidelines for deterring drones.…

A Celebration of Learning at Grace Hopper

Photo by Cloudflare Staff Over the course of my career, I’ve been to many conferences, interacted with thousands of candidates, and attended countless keynotes, roundtables, and sessions. I can say without a doubt, that the Grace Hopper Celebration, stood out from the rest. And I think my team would agree. During the three day event, we screened more than 50 candidates, conducted 24 onsite interviews, and had more than 600 people visit our booth. Not bad for a booth near…

3-D printing of aircraft parts out of titanium

Credit: Tomsk Polytechnic University Physicists from Tomsk Polytechnic University are currently working to create hydrogen-resistant products out of titanium alloys based on additive manufacturing. The production of metal products using the technology ensures less material consumption as well as possibilities to develop complex geometric products. The project is led by Associate Professor Natalia Pushilina at the Department of General Physics. Today, titanium products are widely used in aircraft construction due to their strength. Thus, titanium parts account for 15 to…

Using Sitebuilder to create a DIY Website for your Business

One of the biggest changes the online world has seen in recent years has been the ease with which anyone can create their own website using free tools such as Sitebuilder. There are plenty of DIY software options out there, but this is one of the few that is genuinely free. Here, we take a look at why it makes sense for businesses to make use of this kind of tool, and we will review Sitebuilder against similar software offerings.…

Converting carbon dioxide to carbon monoxide using water, electricity — ScienceDaily

Researchers at the University of Illinois at Chicago and the Joint Center for Artificial Photosynthesis have determined how electrocatalysts can convert carbon dioxide to carbon monoxide using water and electricity. The discovery can lead to the development of efficient electrocatalysts for large scale production of synthesis gas — a mixture of carbon monoxide and hydrogen. “The electrochemical reduction of carbon dioxide to fuels is a subject of considerable interest because it offers a means for storing electricity from energy sources…

Researchers discover that surface polarization in mixed media increases attraction among elements — ScienceDaily

Despite their name, rare earth elements actually aren’t that rare. Abundant in mines around the world, rare earths are used in many high-tech products, including visual displays, batteries, super conductors, and computer hard drives. But while they aren’t necessarily tricky to find, the elements often occur together and are extremely difficult to separate and extract. “Having the ability to recover rare earths is important because they are finite but in high demand,” said Northwestern University’s Monica Olvera de la Cruz.…

Extreme methane rainstorms appear to have a key role in shaping Titan’s icy surface — ScienceDaily

Titan, the largest of Saturn’s more than 60 moons, has surprisingly intense rainstorms, according to research by a team of UCLA planetary scientists and geologists. Although the storms are relatively rare — they occur less than once per Titan year, which is 29 and a half Earth years — they occur much more frequently than the scientists expected. “I would have thought these would be once-a-millennium events, if even that,” said Jonathan Mitchell, UCLA associate professor of planetary science and…

Developer Experience Lessons Operating a Serverless-like Platform At Netflix — Part II

By Ludovic Galibert, Vasanth Asokan and Sangeeta Narayanan In Part 1 of this series, we outlined key learnings the Edge Developer Experience team gained from operating the API dynamic scripting platform which provides a serverless or FaaS like experience for client application developers. We addressed the concerns around getting code ready for production deployment. Here, we look at what it takes to deploy it safely and operate it on an ongoing basis. Deployments Simplicity and abstraction of operations come with…

Border Patrol tests camera-toting balloon

In this undated aerial photo provided by Drone Aviation Corp. shows a tethered balloon, called Winch Aerostat Small Platform, or WASP. The U.S. Border Patrol is considering another type of surveillance balloon to spot illegal activity. It’s part of an effort to see if more eyes in the sky translate to fewer illegal border crossings. (Drone Aviation Corp. via AP) The U.S. Border Patrol is considering another type of surveillance balloon that can be quickly moved to spot illegal activity,…
