The fork that helps you lose weight

Introduced at the Consumer Electronics Show in 2013, Hapifork made the jump from MIT research project to consumer household item in an impressively short amount of time. Perhaps it’s because we all want to lose weight — but we want someone or something else to do the hard work for us.

The chunky, $100 fork, which comes in five colors, alerts you with a gentle vibration when you are eating too quickly. It also measures, using the tines of the fork, how long it took to eat your meal, the amount of “fork servings” taken per minute, and the time between servings. All this information is uploaded — more self-monitoring data — for your own enjoyment or horror, depending on how you eat.

Rose says this is an impressive start, but within the next five years, he anticipates something more draconian: “Imagine an actual tooth replacement that responds to chewing action and is able to sense texture, temperature and chemical content of food and drink,” Rose writes. “In dire circumstances, it magnetically clamps onto the tooth above so you cannot continue to eat.”

The onesie that monitors your baby

High-tech helicopter parent, this one’s for you. The Mimo Baby Shirt measures infant respiration, skin temperature, body position, sleep patterns and activity levels. The organic (of course) cotton onesie is fitted with machine-washable sensors that can be monitored in real time through your home’s Wi-Fi network. It also includes a microphone, so that you can stream your baby’s sound to your smartphone, and the accompanying app allows you to crunch analytics about your baby’s sleep patterns. Originally marketed to medical device development companies, they had a direct-to-consumer eureka moment when parents began contacting them to use their sensors, and, according to their website, they “haven’t looked back since.” For $299 — a package that includes three onesies that come in only one size for infants up to 3 months — you can pick up one of these at your local Babies “R” Us.

Drones and Flying Cars

GPS started out as a military technology but is now used to hail taxis, get mapping directions, and hunt Pokémon. Likewise, drones started out as a military technology, but are increasingly being used for a wide range of consumer and commercial applications. For example, drones are being used to inspect critical infrastructure like bridges and power lines, to survey areas struck by natural disasters, and many other creative uses like fighting animal poaching. Amazon and Google are building drones to deliver household items. The startup Zipline uses drones to deliver medical supplies to remote villages that can’t be accessed by roads. There is also a new wave of startups working on flying cars (including two funded by the cofounder of Google, Larry Page). Flying cars use the same advanced technology used in drones but are large enough to carry people. Due to advances in materials, batteries, and software, flying cars will be significantly more affordable and convenient than tod...

Better Food through Science

Earth is running out of farmable land and fresh water. This is partly because our food production systems are incredibly inefficient. It takes an astounding 1799 gallons of water to produce 1 pound of beef. Fortunately, a variety of new technologies are being developed to improve our food system. For example, entrepreneurs are developing new food products that are tasty and nutritious substitutes for traditional foods but far more environmentally friendly. The startup Impossible Foods invented meat products that look and taste like the real thing but are actually made of plants. Their burger uses 95% less land, 74% less water, and produces 87% less greenhouse gas emissions than traditional burgers. Other startups are creating plant-based replacements for milk, eggs, and other common foods. Soylent is a healthy, inexpensive meal replacement that uses advanced engineered ingredients that are much friendlier to the environment than traditional ingredients. Some of these products...
