Balls

Lab-grown testicle organoids that closely resemble the real thing provide a promising model for research that may help our understanding of testicular development and translate into therapeutic applications for male infertility.

​In a typical tennis practise session, a LOT of balls end up strewn about the court. Bending over and picking them all up is just part of the deal – but perhaps it doesn't have to be, if the ball-collecting Tennibot reaches production.

​We've already seen "smart" soccer balls with integrated sensors that track parameters such as the ball's spin and trajectory. Well, the DribbleUp takes a different approach to smart training. It has markings that allow it to be tracked by a free iOS/Android app.

​When baseball pitchers are practising, three of the main things that they try to improve are the ball's speed, trajectory and spin rate. A group of Taiwan-based entrepreneurs is now offering a new way of measuring these, in the form of the Strike "smart" baseball.​

​It’s estimated that some 230,000 tennis balls get tossed each year after the four Grand Slam tournaments. Now London-based design company Rogue Projects hopes to turn those used balls into functioning and highly portable wireless speakers.

A new initiative by the Los Angeles Department of Water and Power (LADWP) has taken a surprisingly low-tech approach to water conservation, by covering the LA Reservoir in 96 million black "shade balls." It's an attempt to combat water loss through evaporation, and to heighten water quality.

Most dogs enjoy running to get a ball and bringing it back to their owner. It's good exercise, and fun, but it's not a perfect experience for the dog or the dog's owner. The team at Paww is aiming to improve the way we play fetch with our pups with its new smart fetch toys.

Balls made for organized sports are designed to be used at a specific hardness, which is why the TorrX was invented. It's a portable electric pump, that automatically inflates or deflates a ball in order to reach a given pressure.

Purdue University's Professor Mark French and his graduate students, Craig Zehrung and Jim Stratton, have built an air gun that fires a ping-pong ball at over Mach 1.2 (900 mph or 1,448 km/h).

Bounce Imaging is developing a throwable high-tech rubber ball, that will transmit images from hazardous environments to waiting first responders.

The CyberFire Football Set incorporates a reflective foam ball and LED-equipped "glasses," which cause the ball to appear to glow red or green.

The Golf Ball Wrangler is a device that lets entrepreneurs harvest golf balls from the bottom of water traps.
