A new Pacific Salmon Foundation study shows how disputed findings can be turned into alarming headlines,  fuelling the “scientific uncertainty” activists need to kill British Columbia’s ocean salmon farming sector. AnalysisBy Fabian DawsonSeaWestNewsThere is a simple way to make almost any industry look dangerous. Start with something that might pose a risk, present it as evidence of a wider threat, emphasize what scientists still don’t know, then argue that because nobody can prove there is zero risk, government must act before it is too late. That approach became deeply embedded in the Trudeau government’s handling of the B. C. salmon farming file because it also worked politically. It allowed the former government to harvest activist votes while using “scientific uncertainty” to support policy decisions that went well beyond what its own federal science reviews supported. The result was the Trudeau-era decision to end conventional ocean salmon farming in B. C. by 2029, despite federal assessments that had concluded ocean salmon farms posed no more than minimal risk to wild stocks.

The moon is covered with a single tectonic plate like an eggshell. It’s true, the moon is shrinking. And astronomers now know how fast it’s contracting. While only satellite observations and the most delicate instruments can detect these shifts, the consequences of this shrinkage means moonquakes can occur anywhere on the lunar surface at a moment’s notice.

Look up at the night sky with your naked eye and it may seem like it rarely changes. Yet the universe is in constant flux. Stars drift through space, orbiting the centre of the Milky Way as planets orbit them. They rotate, showing off spots on their surfaces and sometimes producing violent outbursts that affect planetary atmospheres much like solar storms produce auroras on the Earth. As stars age, they can die dramatically as supernovae, releasing material that will form the next generation of stars and planets.

A study of DNA from early colonial-era skeletons in a Montreal cemetery has revealed that none of them had any Indigenous ancestry.

Experimental setup behind the TASCA separator: the first detector array, mounted behind the reaction chamber at TASCA, surrounded by two germanium detectors. An international collaboration led by a research group from GSI/FAIR in Darmstadt, Germany, has achieved the first measurement of the chemical stability of a superheavy element compound. The focus was on the hexacarbonyl complex Sg(CO)₆ of seaborgium (Sg, element 106). The result: The bond between the seaborgium atom and a carbonyl ligand is weaker than expected based on its position in the periodic table. The results are published in the journal Nature.

It's one of the oldest questions humans have asked, and as far as we know, our planet is the only one that holds the answer. Earth is also the only planet we know of with plate tectonics, the slow-motion churn of its outer shell that recycles rock, reshapes continents and cycles the nutrients that could feed life. A new international study, published in Nature Geoscience and led by Dr. Hugo Moreira, a Royal Society university research fellow at the University of Portsmouth, is helping us better understand the origins of life by tracing the deep history of Earth's oxygen back billions of years, to a time when the planet and its atmosphere looked nothing like they do today.

Registration and abstract submission close December 15, 2026 We invite the community to a three-day, in-person workshop devoted to ngVLA Science use cases that require the highest spatial resolution capabilities, hosted at the Johns Hopkins University Bloomberg Center in Washington, DC.

Scarlett Middle School science teacher Kristen Tabert was born in Southfield and raised in Brighton. She spent much of her childhood swimming and hiking at Kensington Metropark. Tabert earned a bachelor’s degree in education and a master’s degree in school counseling from Indiana University in Bloomington, where she says she loved her college years. She then moved to Louisville, Kentucky, where she lived for 20 years.

NASA’s Nancy Grace Roman Space Telescope team completed a marathon of activities to fine-tune the observatory’s vision and prepare the primary instrument for routine use. “All of Roman’s sweeping surveys will rely on the Wide Field Instrument,” said Dave Hickey, a Wide Field Instrument systems engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Many of the mission’s primary goals, like studying dark matter and dark energy, wouldn’t be possible without it, so it’s both exciting and a huge relief to see that it’s working well!”
