When we think about workers in an Amazon warehouse, we probably imagine them running down dozens of aisles filled with electronics, clothes, and other items, looking for that one item to box up and send out for swift delivery.

But what if the Amazon site and other company warehouses were run by robots?

In 2012, Amazon bought the warehouse robot maker Kiva Systems, according to Bloomberg, to insure that it had exclusive access to the company’s machines. Now other tech startups are looking to fill the whole left by Kiva’s departure from the open market by developing their own robotic systems geared to the needs of the burgeoning e-commerce sector.

Fetch Robotics in California and Harvest Automation in Massachusetts are two such companies. In one warehouse, eight robots made by Harvest were able to replace a pricey conveyer belt, according to a company spokesman.

Fetch, with a $23 million investment from a Japanese telecom firm, has been selling its robots since this spring for about $25,000. Both Harvest and Fetch are also looking into rental plans, with rates as low as $1.40 per hour, especially for companies that have seasonal warehouse needs during the holidays.

The rise of online shopping has been a boom for the employment market, with warehouse industry jobs up more than 22 percent over a five month period this year compared to last. But as the job market tightens, companies are looking to automation to cut costs.

It’s no secret that the tech sector lacks diversity, especially in higher level positions and in engineering. Now Facebook has a long-term plan for addressing the diversity challenges facing the industry.

This week, the social media leader launched a “Tech Prep” website, according to the Washington Post. The site aims to make educational information and resources on basic computer science and engineering more widely available, especially to young people and parents in low-income African American and Latino areas.

Facebook’s own research showed that African American and Latino parents strongly believe that their children would have the aptitude for computer science, if they had equal access.

Working with the educational software firm McKinsey and Company, Facebook’s Tech Prep site includes resources for ages eight to twenty-five and up, via a mobile-enabled platform and material in both English and Spanish. Some lessons can be downloaded for use offline, and resources can also be tailored by the user’s location.

Facebook is partnering with the Boys and Girls Club and other organizations to promote the site, and Facebook staff will travel to African-American and Latino neighborhoods to demonstrate the offerings. It will also be widely marketed to the one billion users on Facebook.

Facebook believes the site is important not only to foster diversity but also to anticipate a coming jobs crunch. Labor statistics forecast one million unfulfilled programming jobs in the U.S. by the year 2020.

With the advent of computer-aided fitness tracking, weekend warriors are mapping everything from the steps they take on a run to their heart rate and more. But now security experts have revealed that fitness trackers could lead to your computer being compromised.

At a security conference earlier this month, a security researcher from the U.S. firm Fortinet showed how she could hack into a wearers Fitbit fitness tracker in about ten seconds, according to CBS News. The Fitbit’s wireless Bluetooth connection apparently leaves it vulnerable to the hack, which can then infect the user’s computer when the device is connected for downloading.

The Fortinet security staffer Axelle Apvrille showed conference attendees, many of whom were wearing Fitbits, how she could manipulate the equipment’s software and alter data, changing the count of steps taken or distance traveled. Next, she demonstrated that she could upload malware via the Fitbit’s Bluetooth network, which would then corrupt the user’s computer when the user synch’s it to the machine.

While she did not actually infect conference attendees equipment, the “proof of concept” was enough to show that the Fitbit has a small but easily accessed vulnerability to hackers. Apvrille’s demonstration showed that a hacker could simply be in proximity to a user, and within ten seconds complete the upload of malicious software.

Apvrille says she alerted Fitbit about the potential security flaw in March.

With advances in biology and medicine converging with new technologies, it was only a matter of time before a major drug maker and a tech giant got together to develop new medical devices.

Now the pharmaceutical and medical device company Novartis is teaming with Google in developing new contact lenses, according to Fox Business News. Novartis hopes to take advantage of trends that foretell a boon in the eye care market, including an aging population with an increasing need for innovative solutions for improved eyesight.

Novartis is focusing its business on generic drugs and pharmaceuticals in addition to eye care. The company expects to be launching new blockbuster psoriasis and heart disease drugs, and anticipates that emerging markets be more willing to pay market prices for innovative drugs that provide real health benefits.

But Novartis is especially excited with the partnership in eye care with Google. Using the tech company’s experience in eye technology with Google glasses, the contact lenses are expected to make use of built-in sensors that adjust like a camera lens. The contacts will be able to tell when the user is looking closely, as in reading, or looking far away, and will adjust to viewing changes in milliseconds, giving users real-time bifocal abilities.

The company is also looking to develop contact lenses for diabetics that include built-in glucose monitoring.

Novartis has also moved up in its oncology assets, after acquiring the oncology unit from competitor GlaxoSmithKline. The purchase put Novartis in the number two position globally in cancer drug development.

In the classic movie “Who Framed Roger Rabbit,” vividly animated characters interacted with actors in a seamless film reality. Now a tech startup wants to put digital objects all around as, as if they were a seamless part of our world.

The company, Magic Leap, has hundreds of employees in its Florida headquarters, according to the Christian Science Monitor. Earlier this week, the company told investors that its headset would augment users’ reality, weaving virtual objects seamlessly into our environment.

Last year, Google invested more than $500 million in the company. Today, Google’s Alphabet tech incubator division is collaborating to aid in the company’s development.

A company video released earlier this year showed an augmented reality office in which workers could delete emails and arrange files with a swipe of their hands. In addition to headsets, the company is developing a device similar to Google glass, allowing users to view computer-generated images anywhere in their fields of vision.

The company also makes use of independent developers, hosting “app fests” to encourage creativity and involvement with the company’s software. One developer created a virtual cookbook that can be viewed on any kitchen surface.

Magic Leap says it is gearing up for mass production of the systems, though no details were offered about a release date or pricing. Meanwhile, Microsoft is also developing its augmented reality HoloLens technology, which it says will be available sometime in early 2016.
