NASA's Perseverance rover discovers a shiny metallic rock nicknamed 'Phippsaksla' on Mars that scientists believe could be a meteorite from an ancient asteroid.

A small town in the Netherlands hosts the only factory that produces the only chip-making machines that generate a type of light found nowhere naturally on Earth: extreme ultraviolet, a light emitted by young stars in outer space. This light, known as EUV, is the only way to make one of the world's most valuable and important technologies at scale: cutting-edge semiconductor chips. The factory is forbidden from selling its EUV machines to China. Below we explain how the chips are made, why they have become the focus of the US-China trade wars, how Taiwan was drawn into the maelstrom, and what could come next. The answers take us from deep underground to outer space, from the dirtiest places in the world to the cleanest, from the hottest temperatures to the coldest, from man-made structures smaller than a virus to equipment so large it takes three planes to move, and finally, to a state in physics that is two opposites at the same time.

Humor is a central aspect of human communication that has not been solved for artificial agents so far. Large language models (LLMs) are increasingly able to capture implicit and contextual information. Especially, OpenAI's ChatGPT recently gained immense public attention. The GPT3-based model almost seems to communicate on a human level and can even tell jokes. Humor is an essential component of human communication. But is ChatGPT really funny? We put ChatGPT's sense of humor to the test. In a series of exploratory experiments around jokes, i.e., generation, explanation, and detection, we seek to understand ChatGPT's capability to grasp and reproduce human humor. Since the model itself is not accessible, we applied prompt-based experiments. Our empirical evidence indicates that jokes are not hard-coded but mostly also not newly generated by the model. Over 90% of 1008 generated jokes were the same 25 Jokes. The system accurately explains valid jokes but also comes up with fictional explanations for invalid jokes. Joke-typical characteristics can mislead ChatGPT in the classification of jokes. ChatGPT has not solved computational humor yet but it can be a big leap toward "funny" machines.

In 1996 Nasa and the White House made the explosive announcement that the rock contained traces of Martian bugs. The meteorite, catalogued as Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984. Photographs were released showing elongated segmented objects that appeared strikingly lifelike.

This window film (held in fingers at top left) keeps rooms bright and cool by allowing visible light to pass in while reflecting invisible infrared and ultraviolet sunlight and radiating heat into outer space. Credit: Adapted from ACS Energy Letters 2022, DOI: 10.1021/acsenergylett.2c01969 Demand is growing for effective new technologies to cool buildings, as climate change intensifies summer heat. Now, scientists have just designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. They did this with the help of advanced computing technology and artificial intelligence. The researchers report the details today (November 2) in the journal ACS Energy Letters.

If faced with the choice of sending a swarm of full-sized, distinct robots to space, or a large crew of smaller robotic modules, you might want to enlist the latter. Modular robots, like those depicted in films such as "Big Hero 6," hold a special type of promise for their self-assembling and reconfiguring abilities. But for all of the ambitious desire for fast, reliable deployment in domains extending to space exploration, search and rescue, and shape-shifting, modular robots built to date are still a little clunky. They're typically built from a menagerie of large, expensive motors to facilitate movement, calling for a much-needed focus on more scalable architectures -- both up in quantity and down in size. Scientists from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) called on electromagnetism -- electromagnetic fields generated by the movement of electric current -- to avoid the usual stuffing of bulky and expensive actuators into individual blocks.

A new control technology has been developed by scientists for a four-legged robot that allowed it to achieve the "effortless" superhuman feat of hiking 120 vertical metres in the Alps in 31 minutes without any falls or missteps. The advance may lead to the development of new robots and other kinds of robotic technology that can be used in terrain too dangerous for humans, said the researchers, including those from ETH Zurich in Switzerland. The ANYmal quadrupedal robot successfully finished the hike – which consisted of steep sections on slippery ground, high steps and forest trails full of roots – four minutes faster than the estimated duration for human hikers, according to the study, published Wednesday in the journal Science Robotics. "The robot has learned to combine visual perception of its environment with proprioception – its sense of touch – based on direct leg contact. This allows it to tackle rough terrain faster, more efficiently and, above all, more robustly," study co-author Marco Hutter from ETH Zurich said in a statement.

If "sus" and "vent" mean nothing to you, then you've somehow missed out on the smash-hit multiplayer game Among Us. But with numbers playing the online game heading towards 100 million, maybe you'll find out before Christmas how good you are at being an "impostor" . For the uninitiated, Among Us is the sleeper game hit of 2020. The premise is simple: it's Cluedo or Wink Murder on a spaceship with four to 10 players of crewmates and impostors. The crewmates perform simple tasks for take-off, while impostors sabotage operations and kill other players.

Space agencies across the world are working tirelessly to design the best ships and technologies for the chance to claim a stake of the final frontier for their country. Although it may seem like an act of national pride, a professor from Johns Hopkins University warns that space expansion may lead to the extinction of humanity, suggesting it should not be attempted at all. Daniel Deudney recently published a book titled'Dark Skies' that examines space expansionism through geopolitics revealing cosmic habitats could spark totalitarian empires. The political science professor also notes that if these settlements stretch across the solar system, nuclear weapons will become the gold standard in war, along with using asteroids to destroy enemy planets - but other experts feel these arguments are'too pessimistic.' 'I argue that the consequences of what has actually happened in space are much less positive than space enthusiasts and many others believe,' reads'Dark Skies.' 'In sum, this book argues that the large-scale expansion of human activities into space, past and future, should join the lengthening list of catastrophic and existential threats to humanity, and that the ambitious core of space expansionism should be explicitly relinquished.'

Are we here to re-create ourselves as robotic humanoids? In a recent podcast, Robert J. Marks discusses what robots can do for us with retired internist and author Geoffrey Simmons. In his most recent book, Are We Here to Re-Create Ourselves?: The Convergence of Designs (2019), Simmons argues that in creating artificially intelligent robots, we are trying to recreate the human being. But can we really recreate everything about ourselves? For example, they discussed, can robots be counselors? Should robots go into space instead of humans?
