It’s a bit frightening that Wikipedia is the number one source of health information on the internet, but don’t fret. More and more of that information will be coming straight from doctors. Dr. Amin Azzam, a professor at the University of California, San Francisco School of Medicine, is doing his best to get as many doctors on Wikipedia as possible—and he’s doing it by catching them young.

Wearable fitness trackers are certainly en vogue, but they haven’t reached their peak usefulness yet. For a fitness tracker to be more than just a snazzy pedometer, it needs to do more than keep track of how much you’re moving—it needs to act as a personal trainer. That’s what’s driving the creation of Atlas, a much-hyped fitness tracker that could be on the market by the end of the year.

It’s not just about fertility. The age at which you become parents could affect your kids’ mental health.

When you buy a bottle of alcohol, its strength is listed on the label. But in the growing number of US states that allow medical and recreational use of pot, its potency isn’t even regulated, let alone labelled. A new study suggests that the legalization of medical marijuana in particular may have led to more potent, and therefore potentially more dangerous, strains of weed.

Starting this February, you’ll be able to give up real food forever. A year after first blogging about Soylent, a bland shake filled with every micro- and macro-nutrient one needs to survive, Rob Rhinehart tells Motherboard that more than $2 million worth of the powder has been sold, and is almost ready to ship.

It’s been a tough few years for Logitech. The high watermark in sales of PC accessories for the iconic computer mouse and keyboard maker was way back in the last quarter of 2007. So what’s behind the company’s surprisingly strong most recent quarter?

An “exceptional” 29.6 carat blue diamond has been found in Petra Diamonds’ Cullinan mine in South Africa. But how did it get to be that hue in the first place?

Economic theories can really help you up your dating game. Promoting his recent book “Everything I Ever Needed to Know About Economics I Learned from Online Dating,” Paul Oyer wrote on how economic theories can be applied to the world of online dating. Here’s our take, borrowing from Oyer’s insights:

Wikipedia is the leading single source of healthcare information for patients and providers, according to a report on online engagement by IMS Health. According to the study, 50% of surveyed physicians who use the internet have consulted Wikipedia for information—especially on specific conditions. That may explain another finding: That more serious, less common diseases are actually the most frequently searched for by English-speaking Wikipedia users.

The credit card information of 20 million South Koreans has been leaked, state regulators reported on January 19. In a country of 50 million, this marks one of the country’s most devastating security breaches ever. The perpetrator? Allegedly, a single engineer.

Why do viral content sites keep asking you questions and telling you how their videos are going to make you feel? Because those are the links people will click, obviously. A new study confirms this shocking correlation, Forbes reports.

For a wearable device to be successful, it needs to do much more than just work: It also has to look good on you. And not flashy-good—like Google Glass, which marks everyone wearing it as a loud-and-proud early adopter. The design must be able to fully integrate into our day-to-day lives.

Women are more likely to feel shamed or guilted by their physicians than men are, and they’re less likely to make positive changes in response. In a pair of studies published in the journal Basic and Applied Social Psychology, researchers surveyed a wide range of individuals about their experiences with their doctors, asking whether they’d ever been made to feel guilt or shame, as well as how they reacted to those feelings.

Chinese tech counterfeiters couldn’t care less about Samsung’s smartwatch, CNN reports—and that’s bad news. In addition to making electrical components indistinguishable from the ones being ripped off, Chinese counterfeiters are also known for having a lot of savvy when it comes to spotting what’s in demand.

Some of the most famous psychopaths of the silver screen are anything but, according to an extensive analysis by forensic psychiatrist Samuel Leistedt. In fact, you probably have the wrong idea about psychopaths in general—and you almost certainly know a few.

The Food and Drug Administration (FDA) was wrong about the risks posed by genetic testing company 23andMe, according to commentary published in Nature.  

Dancing could help older women fight urinary incontinence, and it seems that video games are the best way to get them moving. A regimen of dance-based video games, a new study shows, could be a cheap and fun form of physiotherapy.

Your pain tolerance may vary depending on the structure of your brain, a new study finds. While most painful sensations are temporary, at least 20% of the global population suffers from chronic pain, and global pain management costs are expected to reach $60 million by 2015. Finding what makes injuries and illness more debilitating for some than others is a vital step in creating better treatments.

Dieting is a multi-billion-dollar industry (just how many billions is astonishingly hard to pin down), yet there’s remarkably little solid information on what works and what doesn’t. Now a startup is hoping to use data to sort it all out.

The future of fully autonomous robots may be built by a company that is laser scanning the boreal forests of Finland with drones. Helsinki-based Sharper Shape is already bringing a new approach to forest surveying, which is vital for Finland’s electricity grid. But its founders also want to be the top vendor of intelligence systems for drones—and not just in Finland. Sharper Shape wants to put a brain in every unmanned aerial vehicle worldwide.

Hobbyists have been assembling personal computers from their components for decades, buying the processors and other parts and putting them together in their basements. Now they’re doing the same for tablet computers.

If it feels like there aren’t enough hours in the day, it’s time to squeeze in a workout.

When it comes to gadgets, the Consumer Electronics Show is generally about showing off. There are of course exceptions, but most of the tech seen at CES is too gimmicky to sell to a broad set of consumers. This year, as usual, a few companies stood out for all the wrong reasons. Here are a few of the gadgets that perplexed us:

The US Centers for Disease Control and Prevention (CDC) just released its annual summary of sexually transmitted diseases (STDs) for 2012, and it contains a grim little datum: With 1.4 million reported cases, chlamydia broke the record (pdf) for the most instances not just of STDs but of any condition recorded by CDC. But because not every disease has to be reported, that just means that it continues to beat out illnesses like rabies and ebola.
