In winter 2023-24, the Great Lakes’ ice cover was near record lows, peaking at just 16%. Researchers explain how diminishing ice could have consequences for fisheries, and how species are evolving.

Phone cameras are an example of what’s called computational photography. Digital tools built into these cameras can enhance your images in real time.
An exciting new experiment is being set up at Yale university in the US.
Observations during historical solar eclipses confirmed Einstein’s theory of gravity, and led to the predictions of black holes.
2024 is a leap year, when the shortest month mops up a bit of leftover time. But the extra day also tells us about space – and our place in it.
A new study shows how artificial light at night scrambles insects’ normal flight patterns, pulling them off course into orbit around the light.
Leonard Cohen, a man about whom surely no Hallmark festive movie will ever be made, dared the Divine to answer humanity’s sorrows.
SAD is a debilitating condition affecting many people, but there is light at the end of the tunnel.
Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.
An astronomer explains why space looks so dark despite containing 200 billion trillion stars.
Three scientists won the 2023 Nobel Prize in physics for their work developing methods to shoot laser pulses that only last an attosecond, or a mind-bogglingly tiny fraction of a second.
They’re heavily promoted. Your optometrist may even prescribe them. But when we looked at the evidence, this is what we found.
Your faithful companion sees the world differently than you do, but it’s a mistake to assume dogs only see black, white and shades of grey.
Scientists show they can create quantum superpositions of sound particles, pointing to the potential for mechanical quantum computers.
Not all lunar eclipses are alike. An astronomer explains the science behind the slight dimming of the Moon on May 5, 2023.
A new way to make high-frequency light could make it easier to look at things 10 times smaller than conventional microscopes can see.
Each rainbow is personal – the rainbow you see isn’t exactly the same rainbow the next person sees. It’s all in the eye of the beholder.
Some parts of North America will witness a total solar eclipse in April 2024. This may seem far away, but you should think about preparing for this rare and fascinating phenomenon.
In an update of one of the most famous experiments in physics, scientists have used ‘slits in time’ to explore the properties of light and ultrafast optical materials.
Evidence suggests that neither books nor electronic devices are directly to blame for the increase in myopia worldwide. Rather, they enhance this phenomenon by keeping children out of the sunlight.
