In one typical minute on this earth, people kill at least 109 339 chickens, 2630 pigs, 922 sheep, 781 goats, and 557 cows, plus a very large number of ducks, horses, turkeys, and rabbits, as well as three camels. And one singularly unfortunate mule. Add it all up and every week well over a billion animals are slaughtered for food, according to the Food and Agriculture Organization of the United Nations.

You may or may not find the death of so many animals unsettling, but it’s hard for anyone to ignore the undisputed environmental and health consequences [PDF] of this massive meat consumption. They include higher rates of greenhouse-gas emissions, water pollution, deforestation, and biodiversity loss. And possibly colorectal cancer as well.

Golf Robot Learns To Putt Like A Pro

Golf Robot Learns To Putt Like A Pro

While being able to drive the ball 300 yards might get the fans excited, a solid putting game is often what separates a golf champion from the journeymen. A robot built by German researchers is quickly becoming a master of this short game using a clever combination of classical control engineering and machine learning.

In golf tournaments, players often scout out the greens the day beforehand to think through how they are going to play their shots, says Annika Junker, a doctoral student at Paderborn University in Germany. So she and her colleagues decided to see if giving a robot similar capabilities could help it to sink a putt from anywhere on the green, without assistance from a human.

Tickle Pill Bug Toes With These Haptic Microfingers

Balloon actuators and liquid metal sensors enable tactile human-insect interactions

All things considered, we humans are kind of big, which is very limiting to how we can comfortably interact with the world. The practical effect of this is that we tend to prioritize things that we can see and touch and otherwise directly experience, even if those things are only a small part of the world in which we live. A recent study conservatively estimates that there are 2.5 million ants for every one human on Earth. And that’s just ants. There are probably something like 7 million different species of terrestrial insects, and humans have only even noticed like 10 percent of them. The result of this disconnect is that when (for example) insect populations around the world start to crater, it takes us much longer to first notice, care, and act.

To give the small scale the attention that it deserves, we need a way of interacting with it. In a paper recently published in Scientific Reports, roboticists from Ritsumeikan University in Japan demonstrate a haptic teleoperation system that connects a human hand on one end with microfingers on the other, letting the user feel what it’s like to give a pill bug a tummy rub.
