In the first assessment of its kind, nearly all of the world’s tree species have been added to the IUCN Red List, which acts as an inventory of species’ conservation status.

I Went To The UK’s Most Haunted Castle And Had My Heartrate Monitored… For Science
Sitting on a heavy wooden bench with torchlight illuminating the cold and breezy dungeon wasn’t what I thought I would be doing on a Tuesday night. Yet, there I was, next to my scared colleague, with a heart monitor on the end of my finger, in supposedly the UK’s most haunted castle, to figure out […]
The Millennium Prizes, And The Reclusive Math Genius Who Turned Down A Million Dollars
On August 8, 1900, at the Second International Congress of Mathematicians in Paris, David Hilbert presented 10 of 23 as-yet unsolved problems that he believed would be the “goals […] toward which the leading mathematical spirits of coming generations will strive.” He was right – though the fact that he was one of the most […]
Why Are Toilets White?
Okay, we know that not all toilets are white – who remembers those avocado and salmon pink bathrooms suites of the UK 1970s? But the vast majority of today’s toilets are white, and this seems to be the case across the world: in private homes, offices, and public bathrooms, apart from those terrifying stainless steel […]

Why Do We Kiss? Its Evolutionary Roots May Lie In The “Groomer’s Final Kiss Hypothesis”
We’ve all been there: You’re on a date with someone, it’s maybe the second or third time you’ve met up, and everything’s going well. Then, as it’s time to part ways, the tension starts to mount. Furtive looks are shared, maybe some blushing, and eventually one of you takes the plunge – you stick your […]
Ice Melting Could Slow Vital Ocean Current – Which Could Slightly Slow Melting
Complementary studies by separate teams have explored the interactions between melting ice in the North Atlantic and the flow of a crucial ocean current. One intensifies the alarm many oceanographers have already expressed: that more rapid melting will cause a crucial part of the Gulf Stream system to slow or even stop, with disastrous consequences. […]
Women In STEM Get Paid 88 Percent Of Men’s Salaries At Most, New Report Finds
Women continue to be massively underrepresented across fields in science, technology, engineering, and mathematics (STEM). A damning new report from UNESCO and the G20 confirms this reality, showing that even with increased awareness of the disparity and drives for change, the situation has only improved very slightly since 2005, when 19 percent of STEM jobs […]
There’s A New “Most Canadian” Animal – And It’s Probably Not What You Expect
Beaver, moose, maybe a polar bear – all distinctly Canadian, right? They’re certainly icons of the North American nation, but when it comes to evolutionary distinctiveness, these animals are by no means the “most Canadian”. It turns out, by this metric, the spiny softshell turtle is in fact Canada’s most unique terrestrial animal. In a […]
The Portal Has Opened In A New US City, As If We Didn’t Learn From Last Time
The Portal – the interactive art installation that connected New York City to Dublin earlier this year and was briefly shut down due to “inappropriate behavior” and other shenanigans (we’re looking at you, Dublin) – has been relocated from NYC to Philadelphia’s Love Park, officially known as John F. Kennedy Plaza. The Portal, which stands […]

Teenagers Publish Trigonometric Proof Of Pythagoras’ Theorem Once Considered Impossible
High school students Calcea Johnson and Ne’Kiya Jackson did something in 2023 that most mathematicians had thought impossible: They discovered a way to prove Pythagoras’ theorem using trigonometry that did not depend on circular reasoning. Now, they have published their work in a peer-reviewed academic paper, while also providing another four such proofs. Pythagoras’ theorem […]
Halloween Traditionally Doubles Up As A Cross-Quarter Day – But What Exactly Is That?
Spooky season is always a good excuse for a celebration, but did you know Halloween also occurs around the same time as an annual astronomical event? That’s right – it’s traditionally considered a cross-quarter day (although that timing is a little off from the “true” day – we’ll get into that later). Cross-quarter days are […]
Why We Fear The Dark – And How To Overcome It
Objectively speaking, there is nothing intrinsically dangerous about darkness. Sure, you might bump into things a bit more if you’re not used to the surroundings, but that’s hardly cause for a panic attack – and yet, for an estimated one in nine US adults, that’s precisely the kind of reaction it can elicit. The question […]

On July 23, 1924, the editor of Scientific American, O.D. Munn, and six members of a scientific investigative committee gathered in a small room on the fourth floor of 10 Lime Street, Boston. It was hot and uncomfortable, after all, the city was experiencing a heat wave. But if there was any unease among the committee […]
New Drugs, Heart Health, And Chimpanzees – Here’s The Latest In Menopause Research
Menopause: it’s a natural part of aging that affects millions of people each year, and yet there’s still plenty that we don’t know about it. It’s widely considered to be understudied and even ignored in the majority of studies investigating the biology of aging. That’s not to say there’s no research on the subject at […]
Smallest Known Complete Dinosaur Eggs Found, First “Black Hole Triple” Challenges Models Of How Giant Stars Die, And Much More This Week
This week, the world’s longest venomous snake, the king cobra, has been found to be four separate species, a new carbon capture design is a major step forward in removing CO2 from the air, and a new implant can detect opioid overdose, give lifesaving drugs, and even call for help.

What Is The Rarest Gemstone?
The world’s rarest gemstone is made of kyawthuite, a transparent reddish-orange mineral that’s known from just one sample housed at the Natural History Museum of Los Angeles County. It was retrieved near Mogok, Myanmar, and recognized in 2015 by the International Mineralogical Association (IMA), whose goal it is to standardize the nomenclature of the 5,000+ […]
