A Silicon Valley startup with Houston roots is helping tackle the COVID-19 pandemic with its smartphone-based coronavirus test.

Milpitas, California-based Luminostics, a University of Houston spinout, is producing millions of its Clip COVID Rapid Antigen Test for U.S. consumers after receiving emergency authorization for the product in December. The emergency approval closely followed the National Institutes of Health awarding a $26.1 million contract to Luminostics to speed up development of the coronavirus test. According to a news release from UH, Luminostics is working on an affordable next generation hardware system to reach the mass over-the-counter market at scale.

Chemical engineers and UH alumni Bala Raja, the CEO, and Andrew Paterson, the chief technology officer, began forming their company in the UH lab of Richard Willson, a professor of chemical and biomolecular engineering and professor of biochemical and biophysical sciences.

The technology developed in the UH lab aims to equip consumers with rapid self-diagnostic tests for the flu, HIV, herpes, and other conditions by detecting the presence of bacteria, viruses, small molecules, hormones, and proteins. But Raja and Paterson put that strategy on hold last year and pivoted to re-engineering their technology for COVID-19 testing. The result: the Clip COVID Rapid Antigen Test.

"When we realized that COVID wasn't just a bad flu and that it was actually gonna go crazy and affect as many people as it has, we decided that everything we've done could be very quickly repurposed to make two different tests," Raja told Inc. magazine in April.

As UH explains, the Clip COVID test relies on a nasal swab, a smartphone clip, and glow-in-the-dark nanoparticles to detect a coronavirus infection within 30 minutes. In the phone, an image processor measures the intensity of the luminescence signal. If the signal is strong enough, the result is positive. If it's weak, the result is negative.

"We live in a world where you can have all your basic necessities delivered to your home through an app, and yet this pandemic has exposed how far behind the diagnostics industry lags compared to consumer technology and the convenience economy," Paterson tells UH.

Funding from the National Institutes of Health, venture capital firm Khosla Ventures, investment firm Lynette Capital, and startup accelerator Y Combinator has helped support the Clip COVID Rapid Antigen Test. The startup entered the Y Combinator program in 2016, a year after Raja and Paterson established Luminostics.

In April 2020, French pharmaceutical giant Sanofi said it was exploring a collaboration with Luminostics on the COVID-19 test.

"The diagnostics industry is saturated with products that cater to big, centralized labs or testing in the doctor's office," Paterson says. "There are many applications where it does make sense to do testing in a centralized lab, but there are dozens of other applications where there should be home-tests and there are not, because few companies have tried to take on the technical and regulatory challenges with developing home-testing."

Remote workers in Houston earn far more than commuters, data shows

by the numbers

In the Houston metro area, it pays to work from home.

Data published recently by the U.S. Census Bureau shows remote workers in the Houston metro earn 40 percent more than their commuting counterparts. For remote workers in the Houston area, median earnings stood at $67,500 in 2023, compared with $48,200 for other workers.

Federal data cited by Visual Capitalist indicates 11.8 percent of the Houston area’s labor pool, or nearly 460,000 people, were remote workers in 2023.

In the Dallas metro area, the difference in median earnings between remote workers and non-remote workers is even more stark. According to Census Bureau data, remote workers there earned $77,000 in 2023 — 50.7 percent more than the $51,100 for traditional workers.

Why the wide gap in pay? The Census Bureau says remote workers are more likely to be older, more likely to be white and less likely to live below the poverty line. All of these traits contribute to higher income.

Among home-based workers in the country’s five biggest metros, median earnings for remote workers were highest in the New York and Chicago areas (over $80,000) and lowest in the Houston area (under $70,000), according to the Census Bureau.

The five-metro comparison also reveals that the Houston area had the highest share (6.8 percent) of all workers, both remote and non-remote, living below the federal poverty level.

In a recent Substack post, urban planner Bill Fulton notes that remote workers in major cities typically earn 50 percent to 80 percent more than other workers do. He declares that “remote workers are far more affluent than everybody else. They are, of course, office workers, not blue-collar or service workers, and they tend to be more highly educated.”

Google teams up with Rice University to launch AI-focused accelerator

eyes on AI

Google Public Sector is teaming up with Rice University to drive early-stage artificial intelligence innovation and commercialization via the new Rice AI Venture Accelerator, or RAVA.

RAVA will use Google Cloud technology and work with venture capital firm Non Sibi Ventures to connect high-potential AI-focused startups with public and private sector organizations. The incubator will be led by Rice Nexus, which launched earlier this year in the Ion District as an AI-focused "innovation factory.”

“Google Public Sector is proud to partner with a leading institution like Rice University to launch the Rice AI Venture Accelerator,” Reymund Dumlao, director of state and local government and education at Google Public Sector, said in a news release. “By providing access to Google Cloud’s cutting-edge AI, secure cloud infrastructure and expertise, we’re enabling the next generation of AI pioneers to develop solutions that address critical challenges across industries and within the public sector. This unique partnership between education and industry will give participants access to cutting-edge research, leading technologists, specialized resources and a collaborative academic ecosystem, fostering an environment for rapid innovation and growth.”

Participants will have access to Google Public Sector’s AI leadership as well as experts from Rice’s Ken Kennedy Institute, which focuses on AI and computing research. It will be led by Sanjoy Paul, Rice Nexus’ inaugural executive director. Paul previously worked at Accenture LLC as a managing director of technology and is a lecturer in Rice's Department of Computer Science.

Rice Nexus will serve as the physical hub for RAVA, but the program will support AI startups from across the U.S., as part of Rice’s Momentous strategic plan, according to the university.

“This hub enables AI startups to go beyond building minimum viable products that meet industry privacy standards by utilizing the latest AI technologies from Google Cloud,” Paul said in the news release. “Our goal is to maximize the return on investment for our corporate partners, driving meaningful innovation that will have lasting impact on their industries.”

The 10,000-square-foot Rice Nexus space currently serves as home base for several startups with ties to Rice, including Solidec, BeOne Sports and others. Read more about the new incubation space here.

Houston’s love for live streaming is growing – and the internet needs to keep up

Tech-Heavy Households

One thing Houston isn’t slowing down on is its love for live streaming. Whether catching the big game, binge-watching a new series, or diving into the latest gaming releases, Houstonians are using the internet more than ever. And with nearly 4 million more people expected to move to the area by 2040, networks have to be ready.

More devices, more streaming, more demand
“Internet usage has been skyrocketing year after year," sts Foti Kallergis, Comcast Texas spokesperson. "The average Xfinity household now has 36 WiFi-connected devices, from smart TVs and phones to tablets, speakers, and even smart fridges."

More than 70 percent of all internet traffic is entertainment, with sports, streaming apps, and games leading the charge — especially here in Houston, where fans never miss a Texans game or a Rockets highlight.

In fact, the past year set records for Comcast’s Xfinity network, with the five biggest days of internet consumption ever happening just in the last few months of 2024, driven by huge sports events and gaming downloads.

A network built for what’s next
As more people move in and more devices come online, Xfinity is constantly upgrading its network to keep up — and stay ahead. Whether you’re working on your laptop, FaceTiming on your iPad, or scrolling on your phone, at home or on the go, the goal is simple: fast, reliable, and seamless connection.

Over the last decade, Comcast has poured $80 billion into strengthening its network and infrastructure across the country. That includes 300,000 miles of fiber — enough to circle the globe 12 times — supporting everything from everyday streaming to powering FEMA and the Department of Defense. And here in the greater Houston area, that same network supports thousands of small businesses, too.

Speed, security, and smarts built in
“It’s not just about staying connected — it’s about staying connected smarter,” adds Kallergis. “Comcast’s network is constantly working behind the scenes to make your experience better. In fact, Comcast rolled out over 350,000 upgrades last year alone, including faster speeds at no extra cost.”

And every 20 minutes, it tests over 4,000 data points across tens of millions of devices to keep things optimized.

Kallergis adds that if there's extra bandwidth, Xfinity modems automatically adjust. If there's a network issue, AI-powered tools fix 60 percent of cases before users even know something’s wrong. And if a fiber line is cut, Xfinity technicians are alerted instantly and know exactly where to go and what to do.

Powerful tools for your home
Great internet also depends on what’s inside your home. That’s why Comcast is rolling out the new XB10 modem — the fastest and most powerful yet. It can handle up to 300 devices at once (because let’s be real, we’re all tech-heavy households now).

And when it comes to security, Xfinity’s network has your back. Every device that connects is automatically shielded from sketchy sites; it's like having a mini cybersecurity team 24/7.

Looking ahead
At the end of the day, Houston’s internet needs are only going to grow. And Comcast is ready.

Whether you’re streaming the playoffs, jumping on a work call, or video chatting with family across the country, Xfinity is here to keep you connected to the moments that matter most.
