A Houston-based company is beginning a push on its proven test for central nervous system (CNS) cancers.

“We're going to start rolling out just in Texas and doing patient testing in the state of Texas, first with a few accounts where we've established a relationship, and then we'll continue our rollout through the United States in the next year or so,” says Russell Bradley, president and general manager of CNSide Diagnostics.

Bradley had retired from multinational diagnostics company Abbott Laboratories when he met Marc Hendrick, the CEO of Austin’s Plus Therapeutics, last year. When Hendrick told him about the recent acquisition of CNSide, a company formerly based in San Diego, Bradley says he felt compelled to join in its mission.

CNSide’s CSF assay tests cerebrospinal fluid for cancers that have metastasized to the spine or brain, primarily carcinomas and melanomas.

“Typically, they do an MRI, and that won't always show anything. If it's early stage, they do cytology, which is not very sensitive at finding cancer cells in the cerebrospinal fluid. By the time they're diagnosed, it can be very late-stage, and oftentimes, in fact, the studies show that half of these patients don't get treated,” Bradley says.

CNSide, then, is a ray of hope for patients who are often consigned to palliative care. By diagnosing their metastasis sooner, physicians have more treatment options to stop the CNS cancer before it’s wreaked havoc. Bradley also points out that once a treatment regimen is underway, doctors can continue to measure the cancer’s progress or lack thereof. He claims that, of the roughly 300 neuro-oncologists in the United States, about 200 have already used the test.

Moving from California to Houston briefly slowed progress for CNSide, but now, matters are moving ahead at a steady clip.

“It takes a little bit of time to establish the test in a new location, move the apparatus and establish the processes,” Bradley says. “You have to get the lab accredited, which we just did. So we're now accredited to run patient samples, and we've really just been doing our research samples as part of the clinical studies.”

Texas institutions, such as the University of Texas - Southwestern, MD Anderson Cancer Center, Mays Cancer Center, Baylor Scott & White Health and Texas Oncology, are beginning to use the technology.

Bradley, who lives in Austin but spends much of his time in Houston, says that the city has been nothing less than an ideal fit for the needs of his growing company and a lab that’s currently hiring. He praises the logistics potential of being close to a major hub, which will eventually be a key factor for getting lumbar puncture samples from around the country to the lab for quick testing.

“I think the business environment in Texas, generally, and in Houston, specifically, for us and the access to talent with a lot of institutions here around the Houston area that graduate the type of people that we want to employ is remarkable. And I'd say the cherry on top is really just access to world-class institutions like MD Anderson. I think from a holistic and comprehensive point of view, Houston has a lot to offer a company like us,” Bradley says.

And ultimately, what brought Bradley and CNSide to Texas is the quest to prolong the lives of people living with cancer. As he puts it, “It's a true privilege—and I know I speak on behalf of the team at CNSide and Plus—to be able to impact these patients and have the tools at this time in the history of cancer diagnostics to be able to really make a difference.”

New Houston-born app OpenToBites connects users over meals in 16 cities

Friends and Food

A Houston-born social is connecting foodies and social butterflies for shared meals. OpenToBites launched on Android on June 18 and iOS on June 22, and is available to use for free in Houston and beyond.

Founded and operated by Houston developer Kelvin John, OpenToBites allows users to connect over meals in 16 cosmopolitan cities. That includes Austin and Houston in Texas, plus other American cities like Denver and New York, and even international destinations including Paris, Tokyo, and Sydney.

The app is built on a simple concept, and a press release emphasizes that it's for anyone who wants "friendly company."

“We built OpenToBites in response to several trends, including the rise of solo travel and the demand for social experiences that don’t feel like dating, networking, or large organized events,” said a spokesperson in the release. “We are not a dating app. We are offering shared food and conversation for people who want simple, in-person meal company in a public setting.”

When signing up, users provide their first name, an optional profile photo, and a short bio. They mark themselves as a traveler, a local, or both, and have the option to select their age range or opt out.

Once a profile is created, the user can search for existing meals or create a meal happening within the next 72 hours. To find an existing meal to join as a guest, they select the city, date, and apply filters for the number of seats, type of cuisine, and whether they want to share food with the table or order their own.

Since someone has to get the party started, users can also take the initiative to start a meal as a host. They'll choose the date, time, and restaurant — anything is on the menu, as long as they can link to the restaurant on Google Maps or its own website.

This divides users into "host" and "guest." Guests request to join a table, and a host can decide to accept the request or not. Guests aren't able to see the exact restaurant until their request is accepted, so hosts have a "helpful note" field to fill out with more information about the restaurant.

A similar app called Timeleft launched in Austin in 2024, acting as a friendship matchmaker for small groups of strangers who answer personality questions, meet at a restaurant for dinner, and decide if they wanted to stay in touch.

Though OpenToBites has a similar concept, it seems to work more like Couchsurfing, an app that connects travelers on their own terms. OpenToBites also emphasizes the immediate over the long-term — the meal itself is the social goal.

OpenToBites is available for free on the App Store and Play Store; the app plans to grow each current city's user base before adding new locations.
