Learning Walks

Emergent control of ant learning walks using the mismatch between path-integration and visual cues

Despite their small brains, desert ants can safely navigate back to their nest after travelling hundreds of metres to find food. This ability relies on visual memories, gathered on initial Learning Walks (LWs), during which ants slowly explore the surroundings of the nest. LWs follow a clear progression: early walks are short, spiraling, and interspersed with pirouettes: brief stops during which the ant perform a visual scan.

Robot fish could unravel how our ancient ancestors first learned to walk

Robot fish could unravel how our ancient ancestors first learned to walk Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers have developed a fish-like robot that shows how some species of modern fish are able to walk on land, and could help unravel how early vertebrates evolved similar abilities hundreds of millions of years ago. Revealing a shared walking pattern Using a combination of their "walking fish" robot and computer models based on observations of real fish,...

Adaptive state-action abstractions via rate-distortion

arXiv:2606.06123v1 Announce Type: new Abstract: When learning to walk, infants seem to address a coarse version of the problem first - stay upright, reach the caregiver - and refine it only when further practice at that resolution stops paying off. Reinforcement learning offers multiple techniques for building simple versions of complex tasks, but lacks general principles for how to dynamically adjust the granularity of these abstractions during learning. This paper proposes one such...

White House drops eerie aliens 'walk among us’ warning — but the truth is much closer to home

FIRST ON FOX: The White House has a new message on aliens: They are not coming from outer space — they are already here and ICE is tracking them.The Trump administration launched Aliens.gov on Thursday, a space-themed immigration enforcement website that turns UFO-style "disclosure" language into a live dashboard on illegal immigrant arrests, migrant encounters and immigration operations nationwide, Fox News Digital learned."They walk among us," the website reads.

Machine Learning-Based Bitcoin Trading Under Transaction Costs: Evidence From Walk-Forward Forecasting

arXiv:2606.00060v1 Announce Type: cross Abstract: This paper investigates whether machine learning forecasts of hourly BTC-USDT returns can be converted into economically meaningful trading performance after transaction costs. Using approximately 70,000 hourly observations from 2018-2026, XGBoost, LSTM, and iTransformer are evaluated in a 27-fold walk-forward protocol. All three models produce positive gross trading performance in selected configurations, but naive sign-based strategies fail...

'I broke my back in 15 places after boy racer 120mph crash - I was pregnant at the time' Chloe Batchelar - who was pregnant when Jack Schofield lost control of his Audi S3 - also suffered burns, two fractures to her neck, a bleed on her heart, and severe head wounds A young mother has revealed how both she and her unborn baby miraculously survived a horrific crash while she was pregnant, after a reckless driver smashed into a tree at 120mph - leaving her trapped in the burning wreckage....

My rookie era: In my 40s I attempted my first multi-day hike – and became a walking cliche

Adult beginners are charming when the stakes are low. Learning the piano at 50 is cute – but nobody ever needed to be airlifted out of a piano recitalI was 43, unfit and burnt out at the end of 2025, when my phone pinged from an old friend:I know this is unlikely but I’m thinking of doing this four-day hike and there are two places available. You stay in huts so there is less gear to carry.

Can trees boost our creativity? My daily forest walks have changed how I write | Ilka Tampke

Ideas come more quickly, my thoughts roam freely, and I’m reminded I am not the main form of life on the planetI park my car near the trail head and leash up my labrador. Mist coils around the stringy trunks of the manna gums and I breathe in a lungful of cold, peppery air. With notebook in hand, I begin to walk.

My walk across America is over, but my mission for South Side kids is not

As I write this, I am sitting in stillness for the first time in a while. I’ve been walking across America for nearly 200 days, and I admit I’m itching to get back onto the open road. I loved the walk — meeting new people, seeing the hidden corners of America, and learning her stories.
