In 2021, mine workers in Morocco made a huge discovery. They found a fossil that scientists believed to be a new species of mosasaur – a large swimming reptile that lived in the same era as the Tyrannosaurus Rex. However, many scientists, including a group in Alberta, are now questioning whether the fossil is real or fake.

Ivan Semeniuk is The Globe’s science reporter. He’s on the show today to explain what we know about this fossil, the feud that it’s provoked between paleontologists and when we might uncover the truth.

Since Wikipedia was founded nearly 25 years ago as a free, online encyclopedia, it has consistently ranked as one of the top 10 most visited websites globally. In an era when so much of the internet is full of misinformation, polarization, and social media platforms designed to keep you doomscrolling for hours, you could argue that Wikipedia – free of ads, and maintained by volunteer editors – is one of the last good places online.

Samantha Edwards is the Globe’s online culture reporter. She’s on the show to talk about what motivates these editors to volunteer, how AI is threatening the site’s future, and why going down a Wikipedia rabbit hole might actually be good for you.

A Globe and Mail investigation has revealed the extent to which Canadians have been caught up in U.S. President Trump’s immigration crackdown.

These Canadians range from 2 years old to 77 years old.

Kathryn Blaze Baum, an investigative reporter for The Globe, joins The Decibel to break down the exclusive reporting, explains what the Canadian government says it’s willing to do and whether advocates think that’s enough.

For decades, scientific research at the Great Lakes has meant close partnership between Canada and the U.S., but President Trump’s latest job cuts may be changing that. In March, the U.S. agencies overseeing the health and conditions of oceans, lakes and rivers became the latest target of the Trump administration’s federal job-cutting spree.

Patrick White reports on water issues for The Globe. Today, he explains how the partnership around the Great Lakes is changing, why there are new negotiations about water sharing, and why these conversations about freshwater are not just issues of environmental concern – but also of national security.

In late July, French President Emmanuel Macron said France would recognize a Palestinian state at the United Nations General Assembly in September.

The conversation around sleep is shifting. Hustle culture views sleep as a waste of time. But in a culture increasingly focused on health and wellness, sleep is seen as something to be optimized and even perfected. Sleep hygiene trends are taking over social media, but experts warn that fixating on rigid routines and products may do more harm than good.

Dr. Rebecca Robillard is a neuropsychologist at the University of Ottawa and co-chair of the Canadian Sleep Research Consortium. Rebecca writes for The Globe’s The Sleep Whisperer, a short series of columns offering advice and insights on sleep health. She’s on the show to talk about the science behind insomnia, explain sleep hygiene trends and the treatments proven to work, and remind sleep perfectionists why keeping a simple bedtime routine is best.
