Are Teens Killing Themselves With Smartphones?

Jean Twenge is a professor of psychology at San Diego State University, and she thinks she knows one surprising reason why the rates of teenage depression and suicide have been climbing steadily since 2012 in the U. S.  She summarizes both her own work and the results of several other social-science studies of the problem in a recent article on the academics-to-the-public website called “The Conversation.” From an analytical view, she and her colleagues seem to have done their homework. …

Volumetric 3-D printing builds on need for speed

Volumetric 3D printing creates parts by overlapping three laser beams that define an object’s geometry from three different directions, creating a hologram-like 3D image suspended in the vat of resin. The laser light, which is at a higher intensity where the beams intersect, is kept on for about 10 seconds, enough time to cure the object. Credit: Lawrence Livermore National Laboratory While additive manufacturing (AM), commonly known as 3-D printing, is enabling engineers and scientists to build parts in configurations…

Pinterest joins the Cloud Native Computing Foundation

Micheal Benedict | Pinterest technical product manager, Cloud & Data Infrastructure We’re excited to announce that Pinterest has joined the Cloud Native Computing Foundation (CNCF). By joining CNCF, we intend to work closely with the community to 1) Share lessons learned from operating Pinterest at scale in a public cloud environment 2) Contribute to cloud-native standards and 3) Adopt, support and collaborate on cloud-native technologies. Background Pinterest is powered by hundreds of microservices on tens of thousands of hosts. Our…

Scientists channel graphene to understand filtration, ion transport into cells — ScienceDaily

Tiny pores at a cell’s entryway act as miniature bouncers, letting in some electrically charged atoms — ions — but blocking others. Operating as exquisitely sensitive filters, these “ion channels” play a critical role in biological functions such as muscle contraction and the firing of brain cells. To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules, particularly water, that have an affinity for the charged…

Talking to ourselves and voices in our heads — ScienceDaily

As far our brain is concerned, talking to ourselves in our heads may be fundamentally the same as speaking our thoughts out loud, new research shows. The findings may have important implications for understanding why people with mental illnesses such as schizophrenia hear voices. UNSW Sydney scientist and study first author Associate Professor Thomas Whitford says it has long been thought that these auditory-verbal hallucinations arise from abnormalities in inner speech — our silent internal dialogue. “This study provides the…

Physicists develop new measurement method for active nanoscale components — ScienceDaily

Whatever the size of mobile phones or computers are, the way in which such electronic devices operate relies on the interaction between various materials. For this reason, engineers as well as researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists of Friedrich Schiller University Jena, Germany, have now developed an innovative method that enables them to obtain several different types of information simultaneously…

Like holiday enthusiasts, majoid crabs decorate their shells — ScienceDaily

‘Tis the holiday season and it seems homes are festively trimmed at every turn. Ornaments of all shapes and sizes embellish everything from trees to windows and yards. While tinsel originated in 17th century German decorating and modern day Christmas lights can be traced to the Victorian era, the idea of decorating is not an exclusively human trait. Majoid crabs — known as decorator crabs — are well-known among marine scientists for adorning their surface with items secured from their…

ONNX V1 released | Engineering Blog | Facebook Code

This post originally appeared on research.fb.com. In September, we released an early version of the Open Neural Network Exchange format (ONNX) with a call to the community to join us and help create an open, flexible standard to enable deep learning frameworks and tools to interoperate. Today Facebook, AWS, and Microsoft are excited to announce that with the support of the community and new partners the first version of ONNX is now production-ready. With ONNX, we are working to create…

Building a new IMDB: Internet Mince Pie Database

CC-BY-SA 2.0 image by Phil! Gold Since joining Cloudflare I’ve always known that as we grew, incredible things would be possible. It’s been a long held ambition to work in an organisation with the scale to answer a very controversial and difficult question. To do so would require a collection of individuals with a depth of experience, passion, dedication & above all collaborative spirit. As Cloudflare’s London office has grown in the last 4 years I believe 2017 is the…

Research team develops novel program to make more cost effective runways

Credit: Texas A&M University An aircraft’s impact on the runway is likely the last thing to cross anyone’s mind when boarding a flight. The constant taking off and landing of aircraft throughout the day places stress on runway pavement, which needs to be in good condition to ensure the safety of the aircraft and its passengers. Thanks to a predictive model developed by a collaborative research team led by the Zachry Department of Civil Engineering at Texas A&M, understanding how…
