NASA say huge man-made structure is actually slowing down Earth's rotation
With the ever-looming Doomsday Clock ticking down, it would be nice to have a little more time every year to get things done, even if most people would spend it staring at their phone.
While you might have thought that this was an impossibility, NASA have now discovered that a major landmark in China is so unbelievably huge that it's actually extended the length of the year by altering the rotation of our planet.
As reported by LADbible, Dr. Benjamin Fong Chao at NASA's Goddard Space Flight Center has revealed research that links the size and weight of the Three Gorges Dam in China to a change in the Earth's orbit.
Completed in 2012, the Three Gorges Dam stretches across the Yangtze River near Sandouping, and is the world's largest power station when considering its installed capacity.
It's also 2,335 meters wide and sits 185 meters above sea level at its peak, costing $20.4 billion in total by the end of its construction.
Due to its ability to hold roughly 40 cubic kilometers - equality to around 10 trillion gallons - of water, the Three Gorges Dam provides a shift in mass that increases the length of every single day on Earth by 0.06 microseconds, making our planet more round in the middle and flatter on top in addition.
Unfortunately, this extension of time isn't something that you would be able to feel in any capacity, as a single microsecond is the equivalent of 0.000001 seconds, so the amount that the Three Gorges Dam actually 'moved' time amounts to just 0.00000006 seconds.
For the Earth to move enough to create a single second of additional time, you'd need the equivalent shift in mass of 16,666,666 Three Gorges Dams, although that might scale a little differently if it all occurred at once!
Dr. Chao has further added that this movement "amounts to a bit more than 3 days over the entire age of the universe," so in the grand scheme of 13.8 billion years, it's not too much to worry about thankfully.
"Can we just take it all at once now in the form of an extra three-day weekend?" jokes one user in a Reddit thread following the news, with another adding that we "slowed down the earth before [we got] GTA 6."
It's certainly another hefty gut punch to any flat Earthers still persisting out there too, although you would have thought that clear evidence from some of the world's most knowledgable scientists would have been enough to convince them otherwise.

NASA Wasn't Happy When Astronaut John Young Smuggled This Food Into Space
On March 23, 1965, NASA launched astronauts Virgil "Gus" Grissom and John Young into orbit on the Gemini III mission. The launch was the result of countless hours of preparation and research, and, of course, millions upon millions of dollars. Every detail of the mission was meticulously planned, including approved foods that could be eaten once up and out of the atmosphere. NASA didn't send many provisions on the mission (it was less than five hours long). In fact, there were only rations for Young. Young took it upon himself to smuggle in a meal for Grissom, one he knew that Grissom enjoyed. The sneaky astronaut tucked a corned beef sandwich on rye bread into his spacesuit without informing NASA, a move which the space giant (and Congress) wasn't happy about once the secret was uncovered. Once the astronauts were in orbit, Young passed the sandwich to his commander, who ate some of the sandwich but hid the remainder in his own pocket. It's unclear when NASA found out about the unapproved food, but the two rule-breakers were disciplined by their employer once the beef was out of the bag. The event even appears in the Guinness Book of World Records as the first food smuggled into space, further cementing the exchange in history. The sandwich (or rather, a replica caked in resin) and the incident is memorialized at the Grissom Memorial Museum in Mitchell, Indiana. You may be wondering what the big deal is. The fact is, any foods allowed to go out of this world are thoroughly vetted because certain items can be downright dangerous for either the astronauts or the spacecraft itself. Read more: Once Popular Sandwiches People Don't Eat Anymore Space food and menu planning are an important part of any space mission. Not only do the nutritional and caloric needs of the astronauts need to be taken into account, but logistics as well. For example, there's limited storage space. If a food is too bulky, it might get banned to prioritize smaller, more calorie-dense items. The lack of gravity is another factor, as is any mess potential. In fact, mess is precisely why bread is on NASA's list of banned foods. Bread crumbs will begin to float in the absence of gravity and could potentially end up in an astronaut's eye or in important equipment. Tortillas are NASA's preferred type of grain. For similar reasons, salt and pepper are also not allowed in space, but that doesn't mean space food must be bland. Liquid seasonings have been developed for astronauts to use. Carbonated drinks like sodas stay on earth. In space, the carbon dioxide (bubbles) in these beverages don't rise up and out of the liquid. If a person were to drink one in orbit, they'd be ingesting more carbonation than they would if they were drinking one on earth. This can cause stomach aches. Space food has come a long way since the first Mercury missions, where food was largely freeze-dried, unappetizing, and packaged in aluminum tubes. As space exploration has evolved, so has the menu for astronauts. It's unclear whether corned beef (which isn't the same as pastrami) on tortillas is allowed to go to infinity and beyond, but we do know that bacon already made it to the moon with NASA's approval.

We're Losing the Plot on AI in Universities
An artificial intelligence furor that's consuming Singapore's academic community reveals how we've lost the plot over the role the hyped-up technology should play in higher education. A student at Nanyang Technological University said in a Reddit post that she used a digital tool to alphabetize her citations for a term paper. When it was flagged for typos, she was then accused of breaking the rules over the use of generative AI for the assignment. It snowballed when two more students came forward with similar complaints, one alleging that she was penalized for using ChatGPT to help with initial research, even though she says she did not use the bot to draft the essay.

Mercury's 'missing' meteorites may have finally been found on Earth
When you buy through links on our articles, Future and its syndication partners may earn a commission. Most meteorites that have reached Earth come from the asteroid belt between Mars and Jupiter. But we have 1,000 or so meteorites that come from the Moon and Mars. This is probably a result of asteroids hitting their surfaces and ejecting material towards our planet. It should also be physically possible for such debris to reach the Earth from Mercury, another nearby rocky body. But so far, none have been confirmed to come from there — presenting a longstanding mystery. A new study my colleagues and I conducted has discovered two meteorites that could have a Mercurian origin. If confirmed, they would offer a rare window into Mercury's formation and evolution, potentially reshaping our understanding of the planet nearest the Sun. Because Mercury is so close to the Sun, any space mission to retrieve a sample from there would be complex and costly. A naturally delivered fragment, therefore, may be the only practical way to study its surface directly — making such a discovery scientifically invaluable. Observations from NASA's Messenger mission have inferred the surface composition of Mercury. This suggests the presence of minerals known as such as sodium-rich plagioclase (such as albite), iron-poor pyroxene (for example enstatite), iron-poor olivine (such as forsterite) and sulfide minerals such as oldhamite. The meteorite Northwest Africa (NWA) 7325 was initially proposed as a possible fragment of Mercury. However, its mineralogy includes chromium-rich pyroxene containing approximately 1% iron. This poorly matches Mercury's estimated surface composition. As a result of this, and other factors, this link has been challenged. Related: Mercury may have a 'potentially habitable' region below its surface, salty glaciers suggest Aubrite meteorites have also been proposed as potential Mercurian fragments. Recent modeling of their formation suggests an origin from a large planetary body approximately 5,000km in diameter (similar to Mercury), potentially supporting this hypothesis. Although aubrites do not exhibit chemical or spectral (the study of how light is broken up by wavelength) similarities with Mercury's surface, it has been hypothesized that they may derive from the planet's shallow mantle (the layer beneath the surface). Despite ongoing research, the existence of a definitive meteorite from Mercury remains unproven. Our latest study investigated the properties of two unusual meteorites, Ksar Ghilane 022 and Northwest Africa 15915. We found that the two samples appear to be related, probably originating from the same parent body. Their mineralogy and surface composition also exhibit intriguing similarities to Mercury's crust. So this has prompted us to speculate about a possible Mercurian origin. Both meteorites contain olivine and pyroxene, minor albitic plagioclase and oldhamite. Such features are consistent with predictions for Mercury's surface composition. Additionally, their oxygen compositions match those of aubrites. These shared characteristics make the samples compelling candidates for being Mercurian material. However, notable differences exist. Both meteorites contain only trace amounts of plagioclase, in contrast to Mercury's surface, which is estimated to contain over 37%. Furthermore, our study suggests that the age of the samples is about 4,528 million years old. This is significantly older than Mercury's oldest recognised surface units, which are predicted (based on crater counting) to be approximately 4,000 million years. If these meteorites do originate from Mercury, they may represent early material that is no longer preserved in the planet's current surface geology. To link any meteorite to a specific asteroid type, moon or planet is extremely challenging. For example, laboratory analysis of Apollo samples allowed meteorites found in desert collection expeditions to be matched with the lunar materials. Martian meteorites have been identified through similarities between the composition of gases trapped in the meteorites with measurements of the martian atmosphere by spacecraft. Until we visit Mercury and bring back material, it will be extremely difficult to assess a meteorite-planet link. The BepiColombo space mission, by the European and Japanese space agencies, is now in orbit around Mercury and is about to send back high-resolution data. This may help us determine the ultimate origin body for Ksar Ghilane 022 and Northwest Africa 15915. If meteorites from Mercury were discovered, they could help resolve a variety of long-standing scientific questions. For example, they could reveal the age and evolution of Mercury's crust, its mineralogical and geochemical composition and the nature of its gases.

Several presentations have already been scheduled for the upcoming Meteoritical Society Meeting 2025 in Australia. We look forward to future discussions that will further explore and refine our understanding of their potential origin. For now, all we can do is make educated guesses. What do you think?
