Antarctic octopuses live in the coldest waters in the world, where temperatures peak at 10°C (50°F) and frequently drop to nearly -2°C (28°F). How these ‘cold-blooded’ creatures survive such extremes has been something of a mystery. Oddball octopuses of the genus Pareledone were recently found to use their three hearts to pump a special type

Earth’s solid iron core isn’t all that it seems. In fact, just this year, scientists discovered that our planet’s innermost orb isn’t smooth, but rather textured; and stops spinning every seven decades before changing direction. Now, in another surprising study, a team of researchers think they have figured out why Earth’s solid iron core is
The Carrington Event was a major reality check for a rapidly industrializing humanity. In September 1859, the Sun unleashed an eruption so powerful it sent electrical currents sweeping across Earth’s surface, wiping out telegraph systems around the world, with fires and mayhem. We’ve not seen its like since, but ancient evidence suggests that our Sun
Details of a 120-million-year-old tectonic plate once a quarter the size of the Pacific have been revealed long after the section of crust was largely subsumed into Earth’s innards. Suzanna van de Lagemaat, a graduate geologist at Utrecht University in the Netherlands, and her supervisor, Douwe van Hinsbergen, deduced the plate’s existence by piecing together
My friend recently changed their favourite celebrity crush from Anna Kendrick toLily James. While some people could see the attraction, others mightnot. So, what is it that attracts us to potential mates? A new study suggests that female animals learn from other females to prefer distinctive males as mates. Sexual selection involves the evolution of
Thanks in part to the atom’s size, a charged variation of gold called Au2+ isn’t commonly found in nature. Scientists from Stanford University, the University of California, Berkeley, and McGill University in Canada have now managed to create and stabilize the rare ion, allowing for a host of new uses for this fascinating elemental metal.
There are a significant number of Anglo-Saxon burials where the estimated anatomical sex of the skeleton does not align with the gender implied by the items they were buried with. Some bodies identified as male have been buried with feminine clothing, and some bodies identified as female have been found in the sorts of “warrior
On July 4, 2023, the Perseverance Rover celebrated its 842nd Martian day on Mars. As the red sky above began to grow dark, the adventurous robot turned its left navigation camera to the hazy horizon. With one snap, it captured a spectacularly alien sunset, around which the red planet’s sky glowed a brilliantly strange cool
Last month was the hottest September on record by an “extraordinary” margin as the world flirts dangerously with breaching a key warming limit, the EU climate monitor said on Thursday. Much of the world sweltered through unseasonably warm weather in September, in a year expected to be the hottest in human history and after the
TAMPA, Fla. — United Launch Alliance launched two prototypes Oct. 6 for the more than 3,200 Project Kuiper broadband satellites Amazon plans to build and deploy over the next six years. An Atlas 5 rocket carrying the satellites lifted off 2:06 p.m. Eastern from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, and
With their bladed paws, wielded by a rippling mass of pure muscle, sharp eyes, agile reflexes, and crushing fanged jaws, lions are certainly not a predator most animals have any interest in messing with. Especially seeing as they also have the smarts to hunt in packs. “Lions are the biggest group-hunting land predator on the
Physics is a marvelous framework for understanding how the Universe works, but there are a few gaps in its coverage. One of those is evolution. Although biology should fall in line with physical theory, as most things do, that theory so far has not been able to predict evolution, and the emergence of traits and
MIT professor Moungi Bawendi is a co-winner of this year’s Nobel chemistry prize for helping develop “quantum dots” – nanoparticles that are now found in next generation TV screens and help illuminate tumors within the body. But as an undergraduate, he flunked his very first chemistry exam, recalling that the experience nearly “destroyed” him. The
In 2009 a giant star 25 times more massive than the Sun simply…vanished. Okay, it wasn’t quite that simple. It underwent a period of brightening, increasing in luminosity to a million Suns, just as if it was ready to explode into a supernova. But then it faded rather than exploding. And when astronomers tried to
The Earth is heating up, and not just its atmosphere and oceans. The soil itself is getting warmer, too, leading to more extreme soil heat around the planet – along with unclear but ominous consequences for surface dwellers like us. We have been underestimating this problem, according to a new study, focusing on rising air
BAKU, Azerbaijan — China will send new modules to its Tiangong space station in coming years to expand the outpost’s volume and capabilities. Future plans for Tiangong were presented at the 47th International Astronautical Congress in Baku Oct. 4. Zhang Qiao of the China Academy of Space Technology (CAST) presented plans to expand Tiangong from
It turns out your cat’s purr is set on autopilot. Researchers have finally discovered the key to these fluff-ball’s signature sound, which involves squishy pads in a cat’s vocal cords. Scientists have puzzled over how cats manage to make their distinctive low-pitched purr, as low frequency sounds are usually made by larger animals with longer
As far as gravity is concerned, both matter and its charge-flipped ‘mirror’ twin, antimatter, deserve a big, warm hug. A recent experiment by international Antihydrogen Laser Physics Apparatus (ALPHA) collaboration achieved the first direct measurement of free-falling antimatter. Had the results been any different, we might have at last had our first solid clue on
When you stroll along a beach, you may look down and spot colorful bits of worn glass mixed in with the sand. But the little treasures you’ve found actually began as discarded trash. As an environmental science professor, I find these gifts from the sea particularly interesting. I have analyzed sand from across the world
Planetary scientists have long known that Mercury has been shrinking for billions of years. Despite being the closest planet to the Sun, its interior has been cooling down as internal heat leaks away. This means that the rock (and, within that, the metal) of which it is composed must have contracted slightly in volume. It
Most gardeners know that earthworms help keep soils healthy, now scientists have assessed just how important their underground activities are to global food production – and how to protect them. In research published Tuesday scientists found that earthworms may be to thank for more than six percent of global grain yields every year, because of
WASHINGTON — A short-term funding bill passed at the last minute includes a three-month extension of the “learning period” limiting regulations on commercial spaceflight participant safety. The House of Representatives and the Senate passed Sept. 30 a continuing resolution (CR) funding the federal government through Nov. 17. The bill passed by wide margins in both
Within the deepest, darkest, and most mysterious place on Earth lie miniscule parasitic monsters. Monstrous to microbes, at least. Researchers have isolated a new type of virus that infects deep-sea Halomonas bacteria. This is the same group of microorganisms that are eating away at the wreck of the Titanic, but the host species in question
Back in 2018, a tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as barely detectable particle slammed through its molecules. It was the first time that water has been used to detect a particle known as an antineutrino, which originated from a nuclear reactor more than 240 kilometers (150
Science is hard. The science of consciousness is particularly hard, beset with philosophical difficulties and a scarcity of experimental data. So in June, when the results of a head-to-head experimental contest between two rival theories were announced at the 26th annual meeting of the Association for the Scientific Study of Consciousness in New York City,
To capture the first image of a black hole, researchers had to build a telescope as big as Earth by stitching together data from observatories around the globe. When the fuzzy, glowing image was finally released in 2019, every major newspaper ran it. Now, that same supermassive monster – which sits at the center of
Our planet has changed a lot over billions of years, from the location of the continents to the makeup of the atmosphere, and a new study looks in detail at the history of the Sahara desert – which wasn’t always an arid wilderness. Researchers from Finland and the UK reconstructed the periodic transformations of the
WASHINGTON — NASA has agreed to extend operations of its New Horizons spacecraft through late this decade to support “multidisciplinary” science that could include another Kuiper Belt object flyby. NASA announced Sept. 29 that it would extend New Horizons, currently approved for operations through the end of fiscal year 2024, until the spacecraft exits the
Orcas have been killing great white sharks off South African shores. But lately, there’s been a mysterious disappearance of great white sharks in these waters. Scientists suggest that the remaining great whites who survived moved east to avoid trouble. For years, great white sharks were turning up dead on South Africa’s False Bay and Gansbaai
A strange pair of galaxies several billion light-years away could be evidence of a hypothetical ‘crease’ in the Universe’s fabric known as a cosmic string. According to an analysis of the properties of the pair, the two galaxies may not be distinct objects, but a duplicate image caused by a trick of the light. And
