We intuitively understand that the sand pouring through an hourglass, for example, forms a neat roughly pyramid-shaped pile at the bottom, in which the grains near the surface flow over an underlying base of stationary particles. Avalanches and sand dunes exhibit similar dynamics. But scientists at Lehigh University in Pennsylvania have discovered that applying a magnetic torque can actually cause sand-like particles to collectively flow uphill in seeming defiance of gravity, according to a September paper published in the journal Nature Communications.
Sand is pretty fascinating stuff from a physics standpoint. It's an example of a granular material, since it acts both like a liquid and a solid. Dry sand collected in a bucket pours like a fluid, yet it can support the weight of a rock placed on top of it, like a solid, even though the rock is technically denser than the sand. So sand defies all those tidy equations describing various phases of matter, and the transition from flowing "liquid" to a rigid "solid" happens quite rapidly. It's as if the grains act as individuals in the fluid form, but are capable of suddenly banding together when solidarity is needed, achieving a weird kind of "strength in numbers" effect.
But grains of sand that collectively flow uphill? That is simply bizarre behavior. Lehigh University engineer James Gilchrist manages the Laboratory for Particle Mixing and Self-Organization and stumbled upon this odd phenomenon while experimenting with "micro-rollers": polymer particles coated in iron oxide (a process called micro-encapsulation). He was rotating a magnet under a vial of micro-rollers one day and noticed they started to pile uphill. Naturally he and his colleagues had to investigate further.

Powering the watch is the hand-winding Sellita SW210.M1 in our unique execution of skeletonized rhodium bridges and a dark matte anthracite base. It is paired with a color-neutral mid-grey calf strap from Jean Rousseau to enhance the color of the dial.
I took my apple watch to the beach and inevitably got sand in it. At work we have some compressed air that we usually use for cleaning electronics on racing drones. I was wondering if this could damage it, if it would just get stuck further in, or if it definitely won't have any effect.
So I went to the beach today and spent some time in the sea with my 645. Now when I push the buttons there's a gritty sound, like there's a little bit of sand in the buttons. What's the best way to fix this?
By making estimates of extractions and locations available for all, the goal of the platform is to increase transparency, push for better management of sand resources, and engage with the dredging sector to reduce environmental impact through higher standards. The event, organized by UNEP/GRID-Geneva and the Geneva Environment Network will showcase the platform, discuss the need for better monitoring, and steps to identify good practices and implement higher standards.
The UN Environment Programme has been calling for better monitoring of sand extraction and use, the ban of sand extraction for the purpose of mining sand as a resource in the active beach-nearshore sand system and to establish an international standard on sand extraction in the marine environment.
The new platform provides information on areas used for sand extraction (sand concessions), areas of capital and maintenance dredging, sand trading ports/hubs, number of vessels and operators, and extraction of sediment and other types of activities by countries with Exclusive Economic Zones. The Marine Sand Watch cannot yet detect artisanal and very small-scale mining along very shallow coastlines, despite its intensity in some regions.
The Marine Sand Watch estimates that between 4 and 8 billion tons of sand and other sediments are dredged every year in the marine and coastal environment. Furthermore, data analysed for the years 2012-19 shows the scale of dredging is growing. The world is approaching the natural replenishment rate of 10 to 16 billion tons per year which is needed by rivers to maintain coastal and marine ecosystem structure and function. This is especially concerning for regions where dredging is more intense and extraction already substantially surpasses the sediment budget from land to sea.
Shallow sea mining for sand and gravel is central to various construction activities. It poses a threat to coastal communities in the face of rising sea levels and storms, as marine sand will be needed to build coastal defences, and support offshore energy infrastructure such as wind or waves turbines. Sand extraction puts coastal and seabed ecosystems at risk, including marine biodiversity affected by water turbidity and changes in nutrient availability and noise pollution. Coastal or near-shore extraction can also affect the salinization of aquifers and future tourist development.
In its 2022 Sand and Sustainability report, UNEP calls for better monitoring of sand extraction and use, the report recommended to stop the sand extraction on the beaches and active beach-nearshore sand system for the purpose of mining sand as a resource and to establish an international standard on sand extraction in the marine environment.
The work by UNEP/GRID-Geneva follows a UN Environment Assembly resolution to strengthen scientific, technical and policy knowledge with regard to sand, and to support global policies and action regarding its environmentally sound extraction and use.
HYDRO PUSHERS Many models in the Freestyle line have Hydro-Pushers. This means that you can push the buttons under water without worry of getting water inside your watch. Refer to the Details section for your watch to see if it has Hydro-Pushers.
Our favorite retro chronograph watch now runs on the sun with a solar-powered movement, and features responsible design elements like an ocean plastic case and animal-free straps. Say yes to the unconventional.
Built with solar cells under its dial that absorb light to charge its battery, this watch ticks by sunlight. It naturally charges during the daytime, and can also absorb its power from artificial light, too.

Inspired by the golden age of the dive watch, the Fleuss is built with a nod to nostalgia. Utilising the best in watchmaking techniques, it's a sturdy, ever-dependable timepiece that goes from beach to boardroom with ease.
Equally at home in the desert or on the underground, the Haskell Sand is a master of versatility and performance. The textured sandpaper dial colourway flits from glimmering golden desert to matte sandstone to white-sand beach, depending on how the light catches it.
The Haskell caseback celebrates the spirit of adventure and reference the origin of its name - with the inner section gently domed to represent the globe, with a polished and sand-blasted map showing Antarctica.
Thanks for your tip! I contacted Garmin and explained the situation again. They now offered me a free watch band as it broke within the warranty period. They indeed recommended me to replace the black buckle with the golden one I already have. Seems like we found a solution

Due the to double-layer construction, this design is similar to our regular military straps, but it does not have the additional material that doubles up behind the watch case, making this strap more streamlined and less bulky on the wrist.
If you are new to this style of watch strap, please see our fitting guide on how to fit and wear a military watch strap. And to read more about our different military watch strap collections, please read our blog article that covers the different types.
There are several different styles buckles available, the most common type of watch strap buckle is a pin (tang) buckle. It features a traditional tang and pin system, where the tongue of the buckle is inserted through the holes on the strap, and a pin holds it in place.
