A new report takes the temperature of urban heat islands across the U.S., and Houston lands in the hotter-than-you-know-what category.

The report, released July 14 by the nonprofit news organization Climate Central, ranks Houston the fourth worst place among the country's urban heat islands. Houston sits behind New Orleans, holding down the No. 1 spot, with Newark, New Jersey, at No. 2 and New York City at No. 3.

"Even for a Houstonian, it's easy to think first of flooding or hurricanes when it comes to regional climate impacts, but increases in daytime and nighttime temperatures at the rate we've seen since the 1970s can do as much — if not more — damage," the Nature Conservancy of Texas notes in a July 2020 news release.

Climate Central emphasizes that extreme urban heat is a public health threat. Texas, Arizona, and California accounted for 37 percent of the country's heat-related deaths between 2004 and 2018, according to U.S. Centers for Disease Control and Prevention (CDC) data released in 2020.

According to the Climate Central report, Houston scored so high because of the city's sizeable share of impermeable surfaces, such as asphalt, concrete, stone, and brick. Impermeable surfaces absorb heat and prevent water from penetrating them.

Climate Central describes urban heat islands as big urban locations that are hotter that outlying areas, especially during the summer. Neighborhoods in a highly developed city can experience peak temperatures that are 15 to 20 degrees above nearby places that have more trees and less pavement, the group says.

The nonprofit created an index to evaluate the intensity of urban heat islands and applied it to 159 cities across the U.S., with Houston claiming the No. 4 spot.

"Heat islands are heavily influenced by albedo, which measures whether a surface reflects sunlight or absorbs and retains the sun's heat," Climate Central says. "Other factors include the amount of impermeable surface, lack of greenery and trees, building height, and heat created by human activities."

Results of a one-day study carried out last August support Climate Central's conclusion about Houston.

The study mapped out heat islands across 320 square miles of Houston and Harris County. More than 80 community scientists fanned out to sample temperatures during three one-hour periods last August 7.

The hottest point measured during the heat-mapping day was 103.3 degrees just southwest of the Galleria on Richmond Avenue near Chimney Rock Road. At the same time, volunteers recorded a temperature of 86.2 degrees about 20 miles to the east on Woodforest Boulevard in Channelview. The result: a 17.1-degree temperature swing between Houston and Harris County's hottest and coolest areas at the same point in time.

The Houston Harris Heat Action Team — a collaboration among the Houston Advanced Research Center, the City of Houston, Harris County Public Health, and the Nature Conservancy of Texas — sponsored the heat-mapping exercise with financial support from Lowe's and Shell.

"The data has identified Houston's 'hot spots' and shows that some Houstonians are impacted by urban heat island effect more than others," Houston Mayor Sylvester Turner said in a January news release about the heat-mapping study. "We will work with partners to target our cooling and health strategies … to better help Houstonians beat the heat."

The heat-mapping event was conducted in conjunction with Resilient Houston, the city's campaign to make Houston neighborhoods greener and cooler. The City of Houston says data from the heat-mapping study will help with evaluation of health risks related to extreme heat, coordination of tree plantings, installation of shade-producing structures, establishment of cooling centers, and targeted design of parks, streets, housing, and other infrastructure.

"Science shows that there is real potential to reshape our built environment and cool our cities down where it's needed most," says Suzanne Scott, director of the Nature Conservancy of Texas. "And now, armed with this data, local planners, developers, and environmental groups like ours will be able to leverage smart, cooling urban design strategies that offer multiple benefits — including climate resilience — for all residents, both human and wildlife."

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.

Elon Musk's SpaceX site officially becomes the city of Starbase, Texas

Starbase, Texas

The South Texas home of Elon Musk’s SpaceX rocket company is now an official city with a galactic name: Starbase.

A vote Saturday, May 3, to formally organize Starbase as a city was approved by a lopsided margin among the small group of voters who live there and are mostly Musk’s employees at SpaceX. With all the votes in, the tally was 212 in favor to 6 against, according to results published online by the Cameron County Elections Department.

Musk celebrated in a post on his social platform, X, saying it is “now a real city!”

Starbase is the facility and launch site for the SpaceX rocket program that is under contract with the Department of Defense and NASA that hopes to send astronauts back to the moon and someday to Mars.

Musk first floated the idea of Starbase in 2021 and approval of the new city was all but certain. Of the 283 eligible voters in the area, most are believed to be Starbase workers.

The election victory was personal for Musk. The billionaire’s popularity has diminished since he became the chain-saw-wielding public face of President Donald Trump’s federal job and spending cuts, and profits at his Tesla car company have plummeted.

SpaceX has generally drawn widespread support from local officials for its jobs and investment in the area.

But the creation of an official company town has also drawn critics who worry it will expand Musk’s personal control over the area, with potential authority to close a popular beach and state park for launches.

Companion efforts to the city vote include bills in the state Legislature to shift that authority from the county to the new town’s mayor and city council.

All these measures come as SpaceX is asking federal authorities for permission to increase the number of South Texas launches from five to 25 a year.

The city at the southern tip of Texas near the Mexico border is only about 1.5 square miles (3.9 square kilometers), crisscrossed by a few roads and dappled with airstream trailers and modest midcentury homes.

SpaceX officials have said little about exactly why they want a company town and did not respond to emailed requests for comment.

“We need the ability to grow Starbase as a community,” Starbase General Manager Kathryn Lueders wrote to local officials in 2024 with the request to get the city issue on the ballot.

The letter said the company already manages roads and utilities, as well as “the provisions of schooling and medical care” for those living on the property.

SpaceX officials have told lawmakers that granting the city authority to close the beach would streamline launch operations. SpaceX rocket launches and engine tests, and even just moving certain equipment around the launch base, requires the closure of a local highway and access to Boca Chica State Park and Boca Chica Beach.

Critics say beach closure authority should stay with the county government, which represents a broader population that uses the beach and park. Cameron County Judge Eddie Trevino, Jr. has said the county has worked well with SpaceX and there is no need for change.

Another proposed bill would make it a Class B misdemeanor with up to 180 days in jail if someone doesn’t comply with an order to evacuate the beach.

The South Texas Environmental Justice Network, which has organized protests against the city vote and the beach access issue, held another demonstration Saturday that attracted dozens of people.

Josette Hinojosa, whose young daughter was building a sandcastle nearby, said she was taking part to try to ensure continued access to a beach her family has enjoyed for generations.

With SpaceX, Hinojosa said, “Some days it’s closed, and some days you get turned away."

Organizer Christopher Basaldú, a member of the Carrizo/Comecrudo Nation of Texas tribe, said his ancestors have long been in the area, where the Rio Grande meets the Gulf.

“It’s not just important,” he said, “it’s sacred.”

Texas-based 'DoorDash for laundry' startup tumbles into Houston market

No Scrubs

Laundry may seem like an endless task that piles up, but a new service offers a solution to overwhelmed Houston families.

NoScrubs, an Austin-based home laundry pickup service has just expanded to Houston. Described by the company as "DoorDash — but for laundry," they wash customer's clothes at local laundromats and return them the same day, folded and ready to be put away.

The service took off like gangbusters in Austin, making an expansion to the state's largest city an obvious choice. It's not universal coverage just yet.

For now, only the following ZIP codes have NoScrubs service available: 77002, 77004, 77005, 77006, 77007, 77008, 77009, 77010, 77018, 77019, 77024, 77025, 77027, 77046, 77056, 77057, 77081, 77098, 77401, 77030, 77003.

A single pickup starts at $40 for 20 pounds of laundry, while the basic monthly subscription is $60 for two pickups. All services use hypoallergenic detergents.

The average American family spends about 240 hours a year on laundry, making it a very time-consuming chore. For people with disabilities, difficult work schedules, and other circumstances, it can be a real help, says co-founder Matt O'Connor.

"Some of our favorite customer stories simply revolve around saving people time when they have something challenging going on," he writes in an email. "For example, one customer reviewed NoScrubs saying 'So happy I could cry! (Partially because I'm pregnant and my emotions are heightened!)...1000% recommend if you have time restrictions or physical restrictions! ' So, whether it’s saving time, the affordability, or the pleasantly surprising turnaround time, NoScrubs has a variety of benefits for any customer."

NoScrubs is also a new opportunity for Houston's gig workers. Because there are no passengers, it can be a safer alternative to driving ride share for women and other people apprehensive about having strangers in their cars. As NoScrubs partners with local laundromats, drivers are also going to centralized locations rather than all over the map, leading to less wear and tear on their cars. The laundromats benefit as well, since NoScrubs loads are ones that would otherwise be done at home.

"Our model makes driving a tiny fraction of the time, so folks who don’t want to wear down their vehicles and spend a ton on gas love working at NoScrubs," added O'Connor.
