Engagement season is in full swing, but even if you're not shopping for a sparkler to put on your beloved's ring finger, you might be in the market for gorgeous diamond earrings, bracelets, or a necklace.

In either case, have you considered lab-created diamonds? Lab-grown diamonds are chemically identical to mined diamonds, and look the same to the naked eye, even to a professional.

They're also the only way to know that your diamond jewelry is 100-percent ethically sourced and not contributing to the social and environmental destruction caused by the mining industry.

"The mining industry causes rapid deforestation, displaces communities (including Indigenous peoples), and harms biodiversity," says Clean Origin co-founder Alexander Weindling. "In 2021, mining companies used 126 gallons of water per carat mined."

Weindling, a third-generation diamond jeweler, started Clean Origin in 2017 with Ryan Bonifacino, combining more than 200 years of diamond expertise with modern, ethical practices. They exclusively sell 100-percent conflict-free, lab-grown diamonds and, when possible, recycled precious metals.

What started out as an online-only company now has showrooms in Houston, Dallas, and Columbus, Ohio, with locations opening soon in Chicago, Southern California, and Northern Virginia.

Customers can meet a qualified jewelry consultant and explore engagement rings, wedding bands, earrings, necklaces, tennis bracelets, and fashion jewelry.

They can also learn how lab-grown diamonds are created just like natural diamonds, using technology that mimics the heat and pressure created by the earth’s crust. These diamonds still have variations like mined diamonds — not all lab-grown diamonds are perfect — and are still measured with the 4 Cs:

  • Cut: how the diamond refracts light. Note: This is different from shape, which refers to the diamond’s physical shape (such as oval, round, etc.).
  • Color: the hue or tint of the diamond.
  • Clarity: the measure of internal or external imperfections.
  • Carat: the weight of the diamond.

All of Clean Origin's diamonds are independently certified to ensure they are of the highest quality.

Some other perks of shopping with Clean Origin include a generous 100-day return policy and free resizing for engagement rings, and all orders include complimentary expedited shipping to ensure your jewelry arrives swiftly and safely.

Clean Origin’s online ring builder helps you envision your or your partner’s dream engagement ring. If you’re just beginning the diamond buying process, schedule a free virtual appointment with one of their qualified jewelry consultants, who will talk you through the process and answer any questions you have about the selection.

And here's the kicker: lab-grown diamonds can be anywhere from 20-40 percent less expensive than mined stones, meaning you can get more wow factor for way less. What's not to love about that?

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
