The hidden ingredients behind AI’s creativity
Researchers have uncovered why diffusion-based AI models appear creative: their so-called creativity arises from technical quirks in the denoising process, locality and equivariance, which force models to generate image patches independently and then assemble them. This mechanism, tested with the ELS machine, can predict AI outputs with ~90% accuracy, suggesting AI creativity may be a predictable by-product of its architecture, offering insights into both machine and human creativity.
What is a famine and who declares one?
The IPC has confirmed famine in Gaza, marking the first in the Middle East, with over 500,000 people starving amid the Israel-Hamas conflict. Gaza relies almost entirely on outside aid after local food production was destroyed. Malnutrition, especially in children, is catastrophic, and starvation is worsening. Experts say the famine is human-caused and could be reversed with immediate food aid, which could save lives and allow recovery within months.
The brain’s map of the body is surprisingly stable — even after a limb is lost
A new brain-imaging study challenges the belief that the brain reorganizes after limb loss. Researchers tracked amputees for up to five years using fMRI and found the primary somatosensory cortex—responsible for sensing the body—remains largely unchanged, contradicting decades of neuroscience. The findings could improve prosthetics, phantom limb pain treatments, and sensory restoration, showing the brain’s body map is more stable than previously thought.
Elon Musk’s xAI sues Apple and OpenAI over AI competition, App Store rankings
Elon Musk’s AI startup xAI sued Apple and OpenAI in Texas federal court, alleging they conspired to block competition and suppress xAI products, including on the App Store. xAI claims Apple’s exclusive deal with OpenAI limits exposure for its X and Grok apps. Musk previously criticized Apple for favoring OpenAI. xAI competes with OpenAI and other AI firms, and Musk is also suing OpenAI over its shift from nonprofit to for-profit.
The surprising foods that lead to better sleep
Eating habits and diet significantly influence sleep quality. Plant-rich diets high in fruits, vegetables, whole grains, dairy, and lean proteins improve sleep by providing tryptophan, melatonin, magnesium, and other nutrients that regulate sleep hormones and reduce inflammation. Meal timing also matters: avoiding large late-night meals and eating consistently during the day helps the brain associate night with sleep. Overall lifestyle, including exercise, light exposure, and mental health, also impacts sleep.
Scientists have identified the origin of an extraordinarily powerful outer-space radio wave
Astronomers detected one of the brightest fast radio bursts (FRB), named RBFLOAT, and traced its origin with unprecedented precision to a star-forming arm of galaxy NGC 4141, 130 million light-years away. Lasting milliseconds, it released as much energy as the sun emits in four days. Likely caused by extreme cosmic events like magnetars, this nonrepeating FRB marks the first precise localization of its kind and opens the way for hundreds of accurate FRB detections annually.
New dinosaur named after record-breaking yachtswoman
A newly discovered dinosaur, **Istiorachis macaruthurae**, featuring a prominent sail along its back, has been named after yachtswoman Dame Ellen MacArthur. Fossils from the Isle of Wight, dating back 125 million years, reveal unusually long neural spines likely used for visual signaling or sexual display. The discovery, led by Jeremy Lockwood, highlights previously unknown diversity among small iguanodontian dinosaurs and offers insights into Early Cretaceous ecosystems in the UK.
Here’s why crypto set the market on fire on Friday
Cryptocurrency markets surged after Fed Chair Jerome Powell hinted at possible interest rate cuts, boosting investor optimism. Ethereum hit a record $4,885, Solana surpassed $200, and Bitcoin rose to $114,700. Stocks also rallied, with the Dow gaining over 800 points and the S&P 500 up 1.5%. The rally was driven by institutional investors seeking higher-risk assets amid potential monetary easing. Analysts see further gains for Ethereum and other cryptos if momentum continues.

2,000-year-old cave, engravings unexpectedly found during rangers’ patrol in Thailand
Rangers in Northern Thailand discovered a previously unknown sandstone cave, **Takung Cave**, during a routine patrol in Phu Khat Wildlife Sanctuary. The cave, hidden for around 2,000 years, contains well-preserved prehistoric engravings, including geometric patterns and three-finger motifs, possibly dating to Thailand’s Metal Age. Experts say the find could shed new light on human occupation, culture, and ecosystems in the Khwae Noi River basin, highlighting the value of forest conservation and patrols.
Nvidia unveils high-tech ‘brain’ for humanoid robots and self-driving cars
Nvidia unveiled **Jetson Thor**, a supercomputer module for humanoid robots, offering seven times more AI compute power and double the memory of its predecessor, Jetson Orin. Powered by Blackwell GPUs, it enables real-time visual reasoning, sensor processing, and autonomous decision-making. Early adopters include Amazon, Meta, and research labs. Nvidia is betting heavily on robotics and AI as multitrillion-dollar growth markets, while humanoid robots continue to advance globally, though widespread adoption remains limited.
