Some of these innovations won’t stay in Las Vegas

A wristband that will help you say “no” to junk food. A machine that will mix drinks for you.

These were among the gadgets showcased this week at the CES technology conference in Las Vegas.

The four-day show, which opened Tuesday, is a place for companies to unveil their products and services for the coming year, though Apple, Google and other tech companies often hold their own announcement events. Streaming services and surveillance technologies are among the hot topics this year.

Here are some highlights from the show.

Nutritional DNA

A London start-up believes it can help you make healthier diet choices at the grocery store - using your own DNA.

DnaNudge collects your DNA through a cheek swab and sends data related to nutrition to a wristband.

Have a genetic predisposition to high blood pressure? Maybe the wristband will tell you to stay away from salty snacks. You scan the barcode on a product, and the wristband turns red or green to indicate whether it may be good for you.

A few services have popped up to map DNA in the hopes of helping people make better diet choices, though some scientists say genetic makeup is just one of many factors in living a healthy lifestyle.

DnaNudge does cheek swabs only in person in London, but it’s working on a mail order service. The company says it destroys all DNA records after giving you the wristband.

Boozy Bots

No need to shake or stir. These machines will mix cocktails for you.

They’re like Keurig coffee machines, but for booze. Drop in a pod filled with ingredients, slide in a glass, and less than a minute later, you’ll have a martini or a Moscow mule.

In fact, one of the gizmos is made by Keurig. Drinkworks by Keurig sells for $299 and can make cosmopolitans and fizzy drinks, such as vodka sodas. Each pod makes one cocktail and costs about $4.

Another robotic bartender, the $350 Bartesian, sells pods for $2.50 each, but they don’t have alcohol. Instead, you fill canisters with your own whiskey, vodka, gin and tequila. The pods mix in juices, herbs and other flavorings. A touch screen on the Bartesian lets you choose how stiff you want your drink. There’s even an option for alcohol-free “mocktails.”

Both machines sit on a counter or table at home. The companies hope to target those who like to host parties but don’t want to stock a bar, don’t know how to make drinks or would rather push a button than spend time putting together a mojito.

What to hack?

Some people go to CES to glimpse the future of consumer technology. Others are looking for the future of what’s going to get hacked.

Cybersecurity firm McAfee says it uncovered security flaws in two gadgets on display.

One is an internet-connected device for opening garage doors. McAfee’s threat research team says the myQ Hub made by Illinois-based Chamberlain Group could be hacked by jamming the radio frequency signals while the garage is being remotely closed. That could lead it to open instead. Chamberlain says it’s fixing its app to prevent this, but chances of a real-world hack occurring are “extremely low.”

McAfee says it also discovered a flaw in British start-up McClear’s Smart Ring, which uses near-field communication wireless technology for unlocking doors. McAfee researchers demonstrated how hackers could easily clone the ring and gain access to a user’s home. McClear didn’t immediately respond to an emailed request for a comment Tuesday.

Privacy by Google

Google is adding a privacy “undo” feature to its Assistant voice technology. Just tell Assistant to disregard something if you happen to notice the device was listening when it wasn’t supposed to. By saying “Hey Google, that wasn’t for you,’’ Assistant will delete whatever you just said.
