I stopped showering for a few days and tried a probiotic for your skin

A startup called Mother Dirt has developed a product called "AO+ mist" — a spray containing a type of bacteria called AOB that you put on your skin, which may restore it to a natural, healthier state.

Our extreme, hygiene-obsessed routines are unnecessary, Jasmina Aganovic, president of Mother Dirt, told Business Insider. "We’ve confused 'clean' with 'sterile,'" she said.

David Whitlock is the founding scientist of Mother Dirt's research partner, AOBiome. Whitlock, who uses the spray religiously, told Business Insider he hasn't showered in 12 years. Of course, Mother Dirt doesn't recommend that its clients do this, and you should definitely still wash your hands.

But just to get a feel for the most extreme case, I attempted to stop showering for a week, and sprayed myself with AO+ mist instead.

Addison Lee has plans to 'tweak' its technology if new regulations that could hurt ridesharing apps in London are approved

Private taxi company Addison Lee says it has already devised solutions in response to a series of strict proposals from London's transport regulator that, if approved, would clamp down on how private hire companies operate.

Transport for London (TfL), the organisation that regulates things like the London Underground and ridesharing apps like Uber, unveiled a list of potential rules in September. 

Some of the proposals are pretty sensible. Drivers would have to speak English and customers may have to be able to book rides in advance, for example. 

But TfL is also considering forcing companies like Addison Lee to introduce a mandatory five-minute wait time before a passenger can begin a journey. Another proposal involves a ban on animated cars in apps so that a customer wouldn't know how far away their ride was.

This man grew a $2 billion business in six years by studying Larry Ellison

Nutanix cofounder CEO Dheeraj Pandey has never hung out with Larry Ellison (though he has hobnobbed with Bill Gates).

But about 12 years ago, he spent a couple of years working at Ellison's company, Oracle, and in that brief time, he became convinced that Ellison was "one of most misunderstood business leaders of our time," Pandey told Business Insider. 

So when he became CEO of his own company, Nutanix, in 2009, he began to seriously study Larry Ellison.

There's a strange trend spreading from Japan of people posting videos of themselves making miniature meals

There's a strange but fun new video trend that started in Japan but is building up into a global YouTube phenomena: Miniature food.

The "Kawaii" (Japanese for "cute") food trend began building pace over the past year. YouTube creators are filming themselves cooking miniature meals using real ingredients and teeny tiny utensils. There's even sized-down crockery and stoves, and often the cooks serve their creations to little dolls and toys.

One of the most popular channels, Miniature Space, which features a nimble-fingered chef making everything from miniature cakes to tiny cheeseburgers, has more than 460,000 subscribers. The most-popular video — a mini food cake — has been viewed more than 3.8 million times.

Another popular video, viewed more than 3.6 million times is this mini pancake.

GOLDMAN: 'Bitcoin was just the opening act, with the Blockchain ready to take centre stage'

Goldman Sachs is a big bull on blockchain, the distributed ledger software that underpins digital currency bitcoin.

In an "Emerging Theme Radar" note sent to clients on Wednesday, the bank says: "While the Bitcoin hype cycle has gone quiet, Silicon Valley and Wall Street are betting that the underlying technology behind it, the Blockchain, can change... well everything."

In its most basic form, the blockchain records ownership of bitcoin and transactions involving the cryptocurrency across a wide network of computers, as opposed to a centralized ledger.

Transactions are signed off by the parties involved using the software, checked by the network or the "crowd," then added to the blockchain — a long string of code that records all activity. Encryption in the software ensure these "blocks" can't be tampered with or altered. And the decentralized nature means the "crowd" police the whole system.

What Mark Zuckerberg can learn from Elon Musk about changing the world (tsla, fb)

Two billionaire events happened last week: Mark Zuckerberg and his wife, Priscilla Chan said they'd give away most of their wealth, and Elon Musk renewed his call for a carbon tax.

Both Zuckerberg and Musk want to change the world. Some have argued that by creating Facebook, Zuckerberg already has.I might argue that Musk hasn't. Yet.

But that doesn't mean he won't ultimately change it in far more profound ways. And both 

Here's who comes after Generation Z — and they're going to change the world forever

Retail and financial strategists have attempted to target Generation Z, the post-1990s generation that doesn't remember a world before the tech boom, as early as 2014

In a note to clients Wednesday, analysts at Goldman Sachs upped the ante, arguing that Gen-Z could be "just as, if not more, influential" as millennials (also known as Generation Y).

But the alphabet ends after Z. What comes next? An answer is emerging.

Futurist, demographer, and TEDx speaker Mark McCrindle is leading the campaign to call anyone born after 2010 a part of Generation Alpha. According to him, 2.5 million Alphas are born around the globe every week.


Astronomers just saw a black hole blow something incredible into space with tremendous force

What would happen if the sun was swallowed by a black hole?

Until now, astronomers could only theorize.

But after an exciting observation recently announced in the journal Science, an international team has witnessed first-hand the violent battle between a sun-like star and supermassive black hole — and its incredible aftermath.

What they observed is an important piece of a much larger puzzle concerning a powerful and perplexing phenomenon called cosmic jets, illustrated to the right. As you can see, rays of radiation are pictured flying out the north and south ends of a black hole.

An unexpected discovery

Tucked away in a nearby galaxy 300 million light years from Earth is a supermassive black hole, the largest kind of black hole that exists in the universe.

VMware might do a big buyback to placate shareholders ahead of the Dell deal (EMC, VMW)

VMware and its parent company EMC are considering a multi-billion stock buyback and other steps to placate shareholder ahead of its massive merger with Dell, according to a report in Bloomberg.

The companies are also weighing a new structure that would consolidate Virtustream, a money-losing business that is slated to become 50-50 joint venture with VMware, into EMC instead, Bloomberg said.

The news follows Dell’s October announcement that it plans to acquire EMC for $67 billion, in the tech industry’s biggest merger ever. The merger is extremely complex, but could create an IT industry powerhouse.
