2019 Reflections from the Science + Technology Desk

It’s been such a great year here on the Science + Technology Desk at The Conversation Canada. We’ve reached hundreds of thousands of readers on topics as wide-ranging as archaeology, animal behaviour, urban planning, new technologies, quantum physics and a lot of outer space. Our work this year led us to be nominated for a 2019 People’s Choice Award for Canada’s Favourite Science Online Site.

One of the best parts of my job is that everyday I feel like I’m attending fascinating and exclusive seminars. All of the stories I work on are my favourites, but there are a few that I keep bringing up over and over again with my friends and family. They’re usually the fodder for interesting conversations about ethics, or along the lines of “Did you know…?” or “You’ll never believe this!”

I’m really fun at dinner parties.

Astrophysicist Toby Brown explored the mystery of missing galaxies in one of our most-read articles of the year. And in other cool jobs — although Earth-bound — rat detective Kaylee Byers wrote about how she tracked rats’ movements throughout the city.

A set of three provocative articles examined the emerging relationships between technology and sex, presenting new ethical perspectives. Neil McArthur and Markie Twist wrote about the developing new sexuality they term “digisexual.”  Rachel Anne Bar, a neuroscientist at Université Laval, looked at the changes to the brain produced by high levels of pornography viewing. The University of British Columbia’s Judy Illes and Farhad Udwalia explored the connections between sex robots and gender-based violence.

There were many archaeological findings this year that taught us more about changes to our planet and its residents. A 310-million-year-old fossilised forest in Nova Scotia contains a possible trove of yet-to-be-discovered animals, wrote Hillary Maddin. Geologists Joshua Davies and Margriet Lantink study rock strata to learn about the Earth’s orbit paths. Mirjanan Roksandic and Joshua Allan Lindal explained what a Neanderthal tooth found in Serbia taught us about human migration.

Many important and urgent arguments about living in today’s technologically driven world were presented by our authors, including Siobhan O’Flynn’s call to protect the data privacy of our children. Jim Davies invited a charming consideration of how self-driving cars could improve the quality of urban life. And Fatemeh Torabi Asr wrote about her work on a tool that uses linguistic analysis to help us identify fake news.

I’m looking forward to 2020, and publishing stories that reveal more of our world — and beyond — to us. I hope you have a relaxing winter break and best wishes for 2020!

The Year in Science + Technology

Something is killing galaxies, and scientists are on the case

Toby Brown, McMaster University

The first ever Canadian-led large project on one of the world's leading telescopes will investigate how the birth and death of galaxies are affected by their environment.

Rat detective uses DNA to uncover how rats scurry around cities

Kaylee Byers, University of British Columbia

Genetic analysis shows that urban rats prefer to stay near their relatives; however, some of them migrate. Knowing this could help with pest control efforts.

For the love of technology! Sex robots and virtual reality

Neil McArthur, University of Manitoba; Markie Twist, University of Wisconsin Colleges and the University of Wisconsin-Extension

Developments in technologies like robotics and virtual reality are opening new possibilities for sexual experiences.

Watching pornography rewires the brain to a more juvenile state

Rachel Anne Barr, Université Laval

Cognitive neuroscience finds that regular consumption of pornography affects the centres of the brain responsible for willpower, impulse control and morality.

Sex robots increase the potential for gender-based violence

Judy Illes, University of British Columbia; Farhad R. Udwadia, University of British Columbia

An increasing demand for sex robots is concerning, as there are ethical concerns about a possible related increase in gender-based violence.

310 million-year-old tree fossils to reveal new ancient animals

Hillary Maddin, Carleton University

Remains found in the Joggins Cliffs at the Bay of Fundy in Nova Scotia reveal further clues about ancient ecosystems.

Rock-solid archives record variations in the Earth’s orbit

Joshua Davies, Université du Québec à Montréal (UQAM); Margriet Lantink, Utrecht University

Layers of rock provide a historical record of variations in the Earth's orbit, revealing information about the planet's climate billions of years ago.

We street-proof our kids. Why aren’t we data-proofing them?

Siobhan O'Flynn, University of Toronto

Google's history of privacy violations is especially alarming when considering the company's reach extends into educational products.

How self-driving cars will make our cities more charming

Jim Davies, Carleton University

An increase in the use of self-driving cars will change parking infrastructure in cities, and hopefully result in more colourful character neighbourhoods.

The language gives it away: How an algorithm can help us detect fake news

Fatemeh Torabi Asr, Simon Fraser University

Using machine learning and natural language processing, researchers are developing an algorithm that can distinguish between real and fake news articles.
