Junos 2023 reminds us how Canadian content regulations and funding supports music across the country

Brian Fauteux, University of Alberta; Andrew deWaard, University of California, San Diego, and Brianne Selman, University of Winnipeg

Here’s how radio Canadian content policy started, and how Canadian legislation, C-11, could contribute to supporting and growing home-grown music in the digital era.

Unlocking secrets of the honeybee dance language – bees learn and culturally transmit their communication skills

James C. Nieh, University of California, San Diego

Honeybees possess one of the most complex examples of nonhuman communication. New research suggests that it is learned and culturally passed down from older to younger bees.

Cells routinely self-cannibalize to take out their trash, aiding in survival and disease prevention

Åsa Gustafsson, University of California, San Diego and Justin Quiles, University of California, San Diego

Cells degrade and recycle damaged parts of themselves through a process called autophagy. When this “self-devouring” goes awry, it may promote cancer and neurodegenerative disease.

Stopping the cancer cells that thrive on chemotherapy – research into how pancreatic tumors adapt to stress could lead to a new treatment approach

Chengsheng Wu, University of California, San Diego; David Cheresh, University of California, San Diego, and Sara Weis, University of California, San Diego

Some cancers are notoriously resistant to chemotherapy and not curable with surgery. Stopping tumors from adapting to the harsh microenvironments of the body could be a potential treatment avenue.

3 reasons local climate activism is more powerful than people realize

Adam Aron, University of California, San Diego

When people work together, they can move governments to action. Just ask the suffragettes. Still, few people do it. A psychologist explains why, and how to turn that around.

Healthy democracy requires trust – these 3 things could start to restore voters’ declining faith in US elections

Sarah Bush, Yale University and Lauren Prather, University of California, San Diego

Despite a midterm election largely free of controversy over its legitimacy, a large percentage of Americans distrust elections. And that’s dangerous for democracy.

Even weak tropical cyclones have grown more intense worldwide – we tracked 30 years of them using currents

Wei Mei, University of North Carolina at Chapel Hill and Shang-Ping Xie, University of California, San Diego

Research shows storms that might have caused minimal damage a few decades ago are becoming stronger and more destructive as the planet warms.

Scientists in Antarctica discover a vast, salty groundwater system under the ice sheet – with implications for sea level rise

Matthew Siegfried, Colorado School of Mines and Chloe Gustafson, University of California, San Diego

Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.

Cyberattacks have yet to play a significant role in Russia’s battlefield operations in Ukraine – cyberwarfare experts explain the likely reasons

Nadiya Kostyuk, Georgia Institute of Technology and Erik Gartzke, University of California, San Diego

Cyberattacks can be devastating, just not on the battlefield, according to researchers who looked at 10 years of armed conflicts around the world.

The sex of your cells matters when it comes to heart disease

Brian Aguado, University of California, San Diego

A one-size-fits-all approach may not be best for treating cardiovascular disease. Taking sex chromosomes into account could make for more effective and equitable care.

Artists’ Spotify criticisms point to larger ways musicians lose with streaming — here’s 3 changes to help in Canada

Brian Fauteux, University of Alberta; Andrew deWaard, University of California, San Diego, and Brianne Selman, University of Winnipeg

A Spotify boycott wouldn’t fix the working conditions of most musicians. Fostering a more equitable, community-based music culture requires changing how we listen to music and support its production.

Pain and anxiety are linked to breathing in mouse brains – suggesting a potential target to prevent opioid overdose deaths

Sung Han, University of California, San Diego and Shijia Liu, University of California, San Diego

Opioids can cause death by slowing breathing to dangerously low levels, or stopping it altogether. Examining one area of the brain may eventually lead to safer painkillers.

The ocean is our greatest climate regulator. It must be a stronger part of climate policy and action

Sarah Seabrook, National Institute of Water and Atmospheric Research; Elisabeth Holland, The University of the South Pacific; Lisa Levin, University of California, San Diego, and Natalya Gallo, University of Bergen

The ocean has been buffering us from the impacts of climate change, but it is reaching the limit of this capacity. Integrating ocean and climate policy will be crucial.

Medicine is an imperfect science – but you can still trust its process

Venktesh Ramnath, University of California, San Diego

A critical care doctor brings a frontlines perspective to the frustration of dealing firsthand with vaccine hesitancy and discusses the limitations of science and medicine.
