Adults can sabotage a student’s path in science or math. Science News for Students

Anyone can be a scientist — if they are willing to work hard. Sometimes, though, kids don’t get that message.

An adult may tell them outright that science or math is not for them. Often, however, the message will be more subtle. Some teacher, parent or role model may say or do something to make a child think that they aren’t — and cannot be — good at science, technology, engineering or math (STEM).  Read more…

Can nicotine protect the aging brain? Science Daily

Everyone knows that tobacco products are bad for your health. However, according to research, it turns out the nicotine itself–when given independently from tobacco–could help protect the brain as it ages, and even ward off Parkinson’s or Alzheimer’s disease.  Read more…

Activity trackers are ineffective at sustaining weight loss. Science Daily

Wearable devices that monitor physical activity are not reliable tools for weight loss, says a new study. The study specifically investigated whether regular use of commercially available activity trackers is effective for producing and sustaining weight loss. Participants without physical activity trackers showed nearly twice the weight loss benefits at the end of the 24 months.  Read more…

Teleportation across Calgary marks ‘major step’ toward creation of ‘quantum internet’. CBC

In a “major step” toward practical quantum networking, researchers at the University of Calgary have successfully demonstrated the teleportation of a light particle’s properties between their lab and the city’s downtown area, six kilometres away.  Read more…

Are robots coming for our jobs? CBC

From self-driving taxis, to drones delivering fast food, it seems like everything is becoming automated. Convenient? Definitely. But at what cost?

A new Forrester research report predicts that in just five years, robots will steal six per cent of U.S. jobs, forecasting that “a disruptive tidal wave will begin” by 2021. It predicts the biggest impact will occur in transportation, logistics, customer service and consumer services.  Read more…

Astronomers unravel the mystery of ‘giant space blob’. CBC

Scientists believe they have figured out why a mysterious giant ball of gas in the distant universe glows so brightly, and the answers may help explain how galaxies are formed.

Lyman-alpha Blobs, or LABs, are faraway clouds of hydrogen gas that can span hundreds of thousands of light-years and emit bright ultraviolet light.  Read more…
