Just larger than a typical human thumb, the new APO5C pocket pump dips below the 1-oz mark. Thanks to its carbon fiber construction, it's nearly half an ounce lighter than the last "lighter than light" miniature pump we looked at.

If your bike has Presta valves on its rims or tubes, you'll know that pumping the tires can be a fiddly business. The Zilch floor pump is claimed to address that problem, with head seals that don't even touch the valve stem until it locks on.

In order to perform trailside repairs, mountain and gravel bikers need two things: a multitool and a compact pump. That's where the Daysaver Incredible Pump comes in, as it's a little pump that accommodates a tool (or two!) within its hollow handle.

Flextail has made it a mission to design battery-powered pumps tiny enough for even the most ultralight of camping trips. All those efforts have led to the new Zero, a pump so small it clips to a keychain and brings automated inflation everywhere.

Pumping up deflated tires has to be one of the most cumbersome tasks on two wheels. The electronic Mini Pump, pitched as the world’s lightest tire inflator, is just the kind of handy gadget that you’ll want to take along for the ride.

While there are already garments which cool or warm their wearer via circulating liquids, those garments tend to be equipped with cumbersome, noisy pumps. An experimental new system, on the other hand, uses interwoven tubular fibers as pumps.

Researchers have developed an implantable pump that can deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo the therapy while going about their day-to-day activities.

How exactly kidney cells transport blood through the organ's tubes has remained a mystery. Now researchers at Johns Hopkins University have investigated the mechanical forces at work and found a previously unobserved pumping action by kidney cells.

Among other items, serious canoeists are advised to carry an extra paddle (in case they lose one) and a bilge pump (in case their boat gets swamped). The Paddle Pump is designed to make things simpler, by combining both tools in one device.
