Effect of odor on helpfulness in rats — ScienceDaily

Despite their reputation, rats are surprisingly sociable and actually regularly help each other out with tasks. Researchers at the Universities of Göttingen, Bern and St Andrews have now shown that a rat just has to smell the scent of another rat that is engaged in helpful behaviour to increase his or her own helpfulness. This is the first study to show that just the smell of a cooperating individual rat is enough to trigger an altruistic and helpful response in…

China and Japan race to dominate the future of high-speed rail

Credit: Pixabay/CC0 Public Domain Japan and China are racing to build a new type of ultra-fast, levitating train, seeking to demonstrate their mastery over a technology with big export potential. Magnetic levitation, or maglev, trains use powerful magnets to glide along charged tracks at super fast speeds made possible by the lack of friction. A handful of short distance and experimental maglev trains are already in operation, but Asia’s two biggest economies are vying to develop what would be the…

Life During the Pandemic: How Are You Connected?

This article appeared in Microwaves & RF and has been published here with permission. Scientists say that we humans owe our large-ish brains and capacity for adaptive behavior to the rapidly changing landscape our earliest ancestors faced over the first 5 million years of existence. Coming up with new solutions to new threats (massive climate and resulting geographical changes)—and then sharing those solutions—created a path to survival. Human brains are essentially social brains, according to Rick Potts, paleoanthropologist and director…

A pocket cooling device based on a cascade mechanism

Recent technological advances have enabled the development of increasingly compact and flexible devices. This includes wearable or portable technology, such as smart watches, earphones or other smart accessories, which can assist human users in a variety of ways. Researchers at University of California, Los Angeles (UCLA) have recently devised a strategy that could enable the fabrication of portable, compact and flexible electrocaloric…

How Medium counts your followers, and the backfills that disrupted it Photo: Crissy Jarvis on Unsplash A recent wave of users have questioned the validity of the displayed number of followers on their profiles. At one point, their follower number increased, some even by the thousands, but then a few weeks later went back down to around where the user originally remembered. Some users were concerned: Were their profiles hacked? Did a wave of users suddenly follow and then unfollow…

To push or to pull? How many-limbed marine organisms swim — ScienceDaily

When you think of swimming, you probably imagine pushing through the water — creating backwards thrust that pushes you forward. New research at the Marine Biological Laboratory (MBL) suggests instead that many marine animals actually pull themselves through the water, a phenomenon dubbed “suction thrust.” The study, published in Scientific Reports, found that small marine animals with multiple propulsers — including larval crabs, polychaete worms, and some types of jellyfish — don’t push themselves forward when they move their appendages,…

Improving Remote Patient Monitoring to Overcome Healthcare Limitations

Download this article in PDF format. The process of remote patient monitoring has been with us for many years. It’s experienced some success, but this platform also has been fraught with problems and limitations. With today’s technology, it’s now possible to solve those problems, remove those limitations, and make significant advances in this healthcare technique. The COVID virus has stretched healthcare resources to the limit and that, in turn, has neglected many non-COVID patients. Improved remote patient monitoring is one…

NameSarina Gaines HometownWildwood, MO Why did you choose to attend Mizzou for the IT program?I chose to attend Mizzou because I wanted to be near home yet far enough away that I could be on my own. I was originally pursuing a degree in computer science, however, after my first year, I realized that the IT program would be best suited for me. When I first enrolled at Mizzou, all I knew was that I enjoyed programming. After speaking with…

Scientists demonstrate how fires burn and spread under different environmental conditions — ScienceDaily

Mechanical engineer Michael Gollner and his graduate student, Sriram Bharath Hariharan, from the University of California, Berkeley, recently traveled to NASA’s John H. Glenn Research Center in Cleveland, Ohio. There, they dropped burning objects in a deep shaft and study how fire whirls form in microgravity. The Glenn Center hosts a Zero Gravity Research Facility, which includes an experimental drop tower that simulates the experience of being in space. “You get five seconds of microgravity,” said Gollner. The researchers lit…

Simple streaming telemetry. Introducing gnmi-gateway: a modular… | by Netflix Technology Blog | Nov, 2020

Introducing gnmi-gateway: a modular, distributed, and highly available service for modern network telemetry via OpenConfig and gNMI By: Colin McIntosh, Michael Costello Netflix runs its own content delivery network, Open Connect, which delivers all streaming traffic to our members. A backbone network underlies a large portion of the CDN, and we also run the high capacity networks that support our studios and corporate offices. In order to design, operate, and measure these networks, we must collect metrics and state data…
