The motivation for his invention came to Aarrav Anil last year when he saw his uncle Arjun, who has Parkinson’s disease, struggle to eat. Some food spilled (溢出) out of his mouth, the rest splattered (溅) on his clothes. Arjun attempted to keep his dignity but the frustration forced him to give up and call his helper to feed him.

The sight of his uncle’s shaking the spoon so violently inspired Aarrav, 17, from Bengaluru, south India, to turn to robotics. He locked himself in his room with microcontrollers, sensors, motors, and a 3D printer. What emerged was a prototype (原型) of a smart spoon that is now undergoing trials at the RV College of Physiotherapy in Bengaluru.

The sensors in the battery-operated spoon detect shaking on one side and activate movement on the other, effectively cancelling out shaking to keep the spoon stable.

“I’ve been fine tuning the design based on the college’s feedback-that it needs to be waterproof so that it can be washed without damaging all the electronics inside; that it must be removable so it can be cleaned and replaced by a fork, ” Aarrav says.

For Aarrav it is the peak of a 10-year interest in mechanics that began when his mother bought him a Lego set. He has now represented India at more than 20 robotics competitions across the world.

When the blueprint for the smart spoon won first prize in the future innovators category at last year’s World Robot Olympiad in Germany, Aarrav felt encouraged to make the prototype.

More than 7 million people in India are estimated to have Parkinson’s disease, a condition in which parts of the brain become progressively damaged and which mainly affects people over the age of 50. Symptoms (症状) include involuntary shaking and stiff muscles. As the disease progresses, eating can become more difficult, forcing people to rely on help from others.

Aarrav’s ambition is that every family that has someone with Parkinson’s will have the smart spoon. He says his uncle Arjun’s words keep echoing (回响) in his mind: “Who would have thought such a small thing could mean the difference between dignity and indignity?”

Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.

Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).

Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.

Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.

The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.
