Fishing is always an exercise in patience, but by the time Jonathan Newar had planned his former work team's trip to New Braunfels, he had already lost all of his. The precious hours he would spend on the water were backed by so much more time reeling in dead ends on potential fishing guides online.

That's because, back then, there were no sites for Houstonians and Texans that compiled information about trips and properly vetted guides, who have to be insured and licensed — until Newar launched Captain in June.

Captain is a business for booking guided fishing trips. It's a little like Yelp for water sports — allowing people to read and write reviews about their experiences with the trips — but they can also book directly on the site, which keeps customers from the hassle of making reservations and lets the guides spend more time on the water and less in the office.

"The guides really love what we're doing," Newar says. "They're jumping on board."

Captain has more than 70 guides, offering over 160 trips, and caters to a market of the outdoor-oriented: fishermen, boaters, campers, the kind of person who spends their weekdays swiveling in a desk chair and weekends spooling line around a fishing rod. That might be a niche market, but it's not a tiny one; In 2016 alone, the U.S. Fish & Wildlife Service reported that Americans spent $46.1 billion on fishing-related expenses.

And that's only fishing. Newar plans to cast a wider net, expanding Captain to include all kinds of outdoor sports trips — kayaking, hiking, rock climbing, mountain biking, and more. Right now, he's working alone to vet all the guides and make sure he gets the information right about each trip — for example, what kinds of fish clients can expect to catch, how long the trip lasts, if alcohol is allowed on the boat and whether the trip is family-friendly.

"It doesn't ruin your trip to not catch fish. Sometimes you don't catch fish," Newar says. "But what really ruins the trip is being paired with a guide who doesn't fit your need."

Captain, which recently completed MassChallenge Texas' inaugural Houston program, hasn't raised money yet — Newar wants to grow the company first, to widen his client base; after all, the Bayou City is a quick drive from plenty of fishing holes. And when Captain gets a full crew, Newar hopes it become a premier site for get people off their computers, out of the house and reconnected to the outdoors.

"We think Captain can solve a lot of interpersonal barriers," Newar says.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
