We could soon be living through the shortest day of our lives. According to reports, Earth is continuingly spinning faster on its axis. While we've known about this phenomenon for a few years now, scientists are paying close attention to the length of the days this summer.
According to a report from Time and Date, July 9, July 22, or August 5 could be the shortest days in recent years. We know for a fact that Earth's rotational speed has been increasing since at least 2020. And each year, we see slightly shorter days during the middle of the year.

Now, it's worth noting that the shortest day of our lives won't be noticeably shorter in the grand scheme of things. In fact, the difference in the Earth's rotational speed that day won't even be noticeable, except when looking at it through the perspective of the atomic clock. That's because while technically shorter, the day will only be around 1.51 milliseconds shorter, at most.
Exactly why the Earth's rotation has accelerated is unclear, but scientists believe it could have a lasting impact. Not only will it shorten our days, but that can also affect a slew of other things, like the global climate and more. While we don't know the exact reason why, we do know that tidal forces from the Moon and Sun contribute to the Earth's rotation.
However, the list of things that can affect the speed of the Earth's rotation, and thus the length of the day, is longer than you'd expect. Most believe that the change is driven by forces within the Earth, but it's impossible to completely rule out atmospheric conditions, too. Still, knowing when the shortest day of our lives will occur is important information if we want to stay up to date with how the Earth is doing as a whole.
It's no secret that the Earth will one day be swallowed up by the Sun. However, until that happens, the Earth will continue to survive as it has for billions of years. And as it survives, the rotational speed that drives our days will shorten and even increase as the forces affecting it change and evolve.
While we don't know which of the three days listed above will turn out to be the shortest day of our lives, we know it's very likely to happen again, at least until the Earth slows down.

AI is learning to lie, scheme, and threaten its creators
The world's most advanced AI models are exhibiting troubling new behaviors - lying, scheming, and even threatening their creators to achieve their goals. In one particularly jarring example, under threat of being unplugged, Anthropic's latest creation Claude 4 lashed back by blackmailing an engineer and threatened to reveal an extramarital affair. Meanwhile, ChatGPT-creator OpenAI's o1 tried to download itself onto external servers and denied it when caught red-handed. These episodes highlight a sobering reality: more than two years after ChatGPT shook the world, AI researchers still don't fully understand how their own creations work. Yet the race to deploy increasingly powerful models continues at breakneck speed. This deceptive behavior appears linked to the emergence of "reasoning" models -AI systems that work through problems step-by-step rather than generating instant responses. According to Simon Goldstein, a professor at the University of Hong Kong, these newer models are particularly prone to such troubling outbursts. "O1 was the first large model where we saw this kind of behavior," explained Marius Hobbhahn, head of Apollo Research, which specializes in testing major AI systems. These models sometimes simulate "alignment" -- appearing to follow instructions while secretly pursuing different objectives. - 'Strategic kind of deception' - For now, this deceptive behavior only emerges when researchers deliberately stress-test the models with extreme scenarios. But as Michael Chen from evaluation organization METR warned, "It's an open question whether future, more capable models will have a tendency towards honesty or deception." The concerning behavior goes far beyond typical AI "hallucinations" or simple mistakes. Hobbhahn insisted that despite constant pressure-testing by users, "what we're observing is a real phenomenon. We're not making anything up." Users report that models are "lying to them and making up evidence," according to Apollo Research's co-founder. "This is not just hallucinations. There's a very strategic kind of deception." The challenge is compounded by limited research resources. While companies like Anthropic and OpenAI do engage external firms like Apollo to study their systems, researchers say more transparency is needed. As Chen noted, greater access "for AI safety research would enable better understanding and mitigation of deception." Another handicap: the research world and non-profits "have orders of magnitude less compute resources than AI companies. This is very limiting," noted Mantas Mazeika from the Center for AI Safety (CAIS). - No rules - Current regulations aren't designed for these new problems. The European Union's AI legislation focuses primarily on how humans use AI models, not on preventing the models themselves from misbehaving. In the United States, the Trump administration shows little interest in urgent AI regulation, and Congress may even prohibit states from creating their own AI rules. Goldstein believes the issue will become more prominent as AI agents - autonomous tools capable of performing complex human tasks - become widespread. "I don't think there's much awareness yet," he said. All this is taking place in a context of fierce competition. Even companies that position themselves as safety-focused, like Amazon-backed Anthropic, are "constantly trying to beat OpenAI and release the newest model," said Goldstein. This breakneck pace leaves little time for thorough safety testing and corrections. "Right now, capabilities are moving faster than understanding and safety," Hobbhahn acknowledged, "but we're still in a position where we could turn it around.". Researchers are exploring various approaches to address these challenges. Some advocate for "interpretability" - an emerging field focused on understanding how AI models work internally, though experts like CAIS director Dan Hendrycks remain skeptical of this approach. Market forces may also provide some pressure for solutions. As Mazeika pointed out, AI's deceptive behavior "could hinder adoption if it's very prevalent, which creates a strong incentive for companies to solve it." Goldstein suggested more radical approaches, including using the courts to hold AI companies accountable through lawsuits when their systems cause harm. He even proposed "holding AI agents legally responsible" for accidents or crimes - a concept that would fundamentally change how we think about AI accountability. tu/arp/md

Rare Jupiter-sized planet discovered 3,200 light-years away using Einstein's space-time warping method
Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 light-years from Earth in the galactic bulge. It takes AT2021uey b 4,170 days to orbit its dwarf star, according to a study published in the journal Astronomy & Astrophysics. According to Live Scence, AT2021uey b's shadow was first spotted in 2021 in data taken by the European Space Agency's Gaia telescope. It took the astronomers multiple check-ins to confirm the details of the planet. The astronomers discovered the planet using microlensing, a method used only three times previously, according to the study. Microlensing, which is based on Einstein's theory of relativity, relies on massive objects moving through the galaxy to warp the fabric of the universe, called space-time. Dr. Marius Maskoliunas, astronomer at Vilnius University and co-author of the study, discussed in a statement posted in just how much work goes into using this method. "This kind of work requires a lot of expertise, patience and, frankly, a bit of luck. You have to wait for a long time for the source star and the lensing object to align and then check an enormous amount of data," Maskoliunas said in the statement. "Ninety percent of observed stars pulsate for various other reasons, and only a minority of cases show the microlensing effect." According to the study, microlensing occurs when a massive celestial body briefly positions itself directly in front of an even more distant star. As the planet settles in front of the star during its journey, the light begins to curve around the planet, magnifying the light of the star. According to the study, this temporary magnified light is what astronomers are searching for. Maskoliunas gave an example of how to imagine how microlensing works. "What fascinates me about this method is that it can detect those invisible bodies. Imagine a bird flying past you. You don't see the bird itself and don't know what color it is — only its shadow," Maskoliunas said in the statement. "But from it, you can, with some level of probability, determine whether it was a sparrow or a swan and at what distance from us. It's an incredibly intriguing process." According to Live Science, there have been nearly 6,000 planets discovered since 1992 using two other more common practices known as transmit photometry and radial velocity. These more common practices will detect planets through host stars becoming dimmer due to said planets. They will also detect the wobble of the planets' gravitational pulls that occur.
