A delicate ecosystem exists in oceans, lakes, rivers, and other waterways. IoT sensors have been used for some time to monitor the underwater health of the various lifeforms that live beneath the water’s surface, particularly in the aquafarm industry. Now, researchers have found a way to hack bivalves with sensors to monitor water pollution.

Bivalves are freshwater and marine molluscs with a shell consisting of two hinged valves connected by a ligament and includes clams, mussels, oysters, and scallops.

Their global decline has prompted active conservation measures. Moreover, continuous behavioral monitoring is a valuable means of detecting the presence of…


Agree 100%. Any credible freelancer doesn't need to use Fiverr, they have their own retainer clients. And yes, it make all of us look bad.


One of the most significant pain points of IoT is battery life. For as long as wearable tech has existed, researchers and enterprises have been searching for new ways to not only prolong the battery life of wearable tech but find sustainable, effective ways to harvest energy.

A new human-machine interface has emerged, which sounds like something out of science fiction: energy harvesting. It’s a combination of engineering, nanomedicine, flexible electronics, and energy storage advancements. What makes it even more impressive is the amount of R&D required. …


Like most tech journalists, I have a graveyard of obsolete IoT devices. There are fitness trackers, earbuds, a drone, homemade connected clothing, smart home light switches, devices for retrofits, and pet toys, to name a few. Overall, at least 95 percent of these products fell victim to planned obsolescence, or the company went bust or withdrew from the product from service. The rest suffer from an absence of “right to repair” options.

The problem of device obsolescence in IoT

While the choice to no longer use a smart device may be the owner’s choice, there’s another problem when it comes to IoT — device obsolescence. A company…

Mobility startups typically have the advantage of youth, agility, an interest in new technology, and an eye to creating future-proof transportation and technologies. However, they also face a number of unique barriers. Fortunately, smart cities have created a valuable space for mobility startups to innovate within.

By 2030, sixty percent of the global population will live in urban areas, and one in every three people will live in cities with at least half a million inhabitants. Many cities have spent part of the last decade embarking on ambitious, smart city projects that aim to make cities not only responsive but…


We’ve recently seen “a perfect storm” in Texas, where unprecedented cold weather hit the energy grid hard. Many power plants were knocked offline, unable to respond to the increased energy demand by people seeking to heat their homes. Others faced fuel shortages. Even wind turbines offered little help, as many were unequipped with the heating required to operate in freezing weather.

The weather left millions of people without power, as providers introduced rolling blackouts to reduce the demand on the grid. Over 50 people died from situations such as car crashes, carbon monoxide poisoning, house fires, and hypothermia. U.S. …


COVID-19 has had a mammoth impact on the travel industry, with many businesses bankrupt and employees left without work. Border closures have hit the aviation industry hard. Fortunately, image recognition, machine learning, IoT, and location intelligence are creating new travel solutions changing the end-to-end passenger experience.

2020 will be known as the year where tourist flights died a thousand deaths. Airlines filed for bankruptcy, pilots and travel agents looked for new careers, borders closed, and many tourists were left stranded due to canceled flights. COVID-19 created the need for greater hygiene and people monitoring to reduce the spread of the…


Postman is a collaboration platform for API development. They recently released the results of its 2020 Postman State of the API Report. The annual report, the largest and most comprehensive survey of the API industry, surveyed more than 13,500 API developers, testers, executives, and others to understand who is working with APIs, how they are getting their work done, and where they see the industry headed.

I sat down with marketing executive Rebecca Johnston-Gilbert and KIn Lane Chief Evangelist at Postman to find out more and discuss some of the key findings from the survey.

Who works with APIs?

Survey-takers were asked about their…


Hackathons have had a long history of bringing people together to develop technological solutions in response to specific problems and challenges. Hackathons can be in-house, focused on a particular technology, a social issue, or policy challenge.

Over the last year, we’ve seen a shift from in-person events as COVID-19 has required extensive efforts to reduce the risk of exposure. While virtual events may lack the in-person experience, they present the opportunity to develop tremendous value and rapid innovation development.

Over merely days, teams can help deep dive on a specific problem and develop, test, and launch prototypes, which if successful…


Inclusive Design is about creating products that can be used by everyone. We take a look at what we can learn from product design.

At any time, 20% of us will have a disability. It may be temporary, situational, or permanent. Inclusive Design is a methodology, born out of digital environments, that enables and draws on the full range of human diversity. Most importantly, this means including and learning from people with a range of perspectives.

Improving your product’s accessibility can enhance the usability for all users, including those with low vision, blindness, hearing impairments, cognitive impairments, motor impairments or situational disabilities (such as a broken arm).

Inclusive Design is about creating technology from websites to platforms, products and devices that can be used…
