Few things get local greenspace lovers more hyped than the upcoming improvements and beautification of our beloved Memorial Park — which is currently undergoing a major transformation. While many of the updates and facelifts are years off, one of the most innovative ventures has reached a new milestone in the much-anticipated Land Bridge and Prairie project.

Installation of the first tunnel arches has started as of December 9, according to the Memorial Park Conservancy. Marked by two separate, 35-foot tall mounds, the Land Bridge will serve as a major connector for park users and wildlife between the north and south sides of the park, Additionally, it will offer new gathering spaces with scenic views of Houston and the project's expansive prairie network.

Once the project is completed, vehicular traffic will traverse a new alignment of Memorial Drive via tunnels through the Land Bridge — two tunnels below each of the mounds (one for each direction of travel), according to a press release. The arch segments now being erected south of existing Memorial Drive are for the two tunnels through the eastern-most mound.

Next up will be erection of the west mound arches; all tunnels are slated for completion and open to traffic by fall of 2021.

These tunnels boast an innovative edge. While most are built through existing hillsides or below ground, the Land Bridge tunnels will be set at the same grade as the existing roadway, prior to installation of the earthwork for the mounds, per a release. The tunnels through the east and west mound measure 400 feet and 560 feet long respectively and are made up of some 620 separate panels, each of which weighs just under 50,000 pounds.

While excitement is looming, traffic on Memorial Drive is no doubt a concern. Sources at Memorial Park Conservancy assure that Memorial will remain open throughout the duration of Land Bridge and Prairie construction. Within the project area, traffic has been reduced from three lanes to two each way.

All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete. The new road alignment with three lanes restored each way will be complete in September 2021, while the Land Bridge is slated for substantial completion by October 2022.

Meanwhile, trees removed from the Land Bridge and Prairie project area (a major concern for locals) will be relocated in areas of the park designated for reforestation, or repurposed as either compost or toewood for streambank stabilization, in keeping with the Master Plan provisions.

Houston park breaks ground on innovative land bridge

now building

Last week, Memorial Park made headlines when it triumphantly opened its lush and verdant Eastern Glades. The 100-acre destination transformed largely inaccessible green space into a destination offering up picnic areas, native wetlands, a savanna, a pine-hardwood forest, green spaces, and miles of accessible trails.

Now, the Memorial Park Conservancy has announced that construction has begun on Memorial Park's Land Bridge and Prairie project. The 100-acre project, slated for completion in late 2022, will create a new community space with enhanced recreation opportunities for park users with "unmatched vantage points of urban skyline views," according to a press release. Memorial Park's prairie, which adjoins the Land Bridge to the north and the south, aims to re-establish endangered native Gulf Coast prairie, savanna, and wetlands.

The Land Bridge and its corresponding prairie are part of the Memorial Park Master Plan, made possible by a $70 million gift from the Kinder Foundation, and associated the Ten-Year Plan.

Commuters, no need to worry: Memorial Drive will remain open throughout the duration of Land Bridge and Prairie construction. Traffic will be reduced from three lanes to two each way beginning September, while a new section of Memorial Drive and the tunnel arch structures for the Land Bridge are completed directly south of the operating lanes.
All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete, according to a release.

Additionally, per the conservancy, the Land Bridge will:


Provide safety and connectivity
This will benefit both humans and animals crossing Memorial Drive. The Land Bridge will establish two dynamic greenspace connections over Memorial Drive that reunite the north and south sides of the Park while expanding the existing trail network and providing increased connectivity within the Park. While the Land Bridge will provide connectivity for Park visitors and wildlife over Memorial Drive, a stream corridor constructed through the Prairie and a culvert will provide connectivity under Memorial Drive. Together these elements will provide much-needed wildlife connectivity within Houston's largest urban wilderness park and to the natural Buffalo Bayou corridor.

Restore nearly 45 acres of native coastal prairie
This will establish a more resilient ecology during natural disruptions and improve animal habitats. Native coastal prairie is one of the most endangered ecosystems in North America, with less than 1 percent of its historic range remaining today. These forthcoming ecosystems will be home to numerous species of flora and fauna.

Create a new destination for visitors
New opportunities include nature education, leisure walking, interval running and cycling, stargazing, relaxing, and more.

Improve stormwater management
The project will detain stormwater that flows through Memorial Park to Buffalo Bayou during heavy rain events, lessening the impact of peak storms. A stream channel constructed through the site, along with the network of native prairie and savanna, will support greater regional biodiversity and act as a green sponge, helping to absorb and clean stormwater. The constructed wetlands will help to purify water and reduce roadway pollutants that would otherwise be released into the watershed.

"From aiding with critical stormwater management to granting people and wildlife safer crossing over Memorial Drive to providing a dynamic outdoor destination for all visitors, the Land Bridge and Prairie will be an asset not just for Memorial Park but for all Houstonians," said Mayor Sylvester Turner in a statement. "It's about unifying both sides of the Park and giving people a new landmark that they can be proud of and use to enjoy nature."

3 ways the Memorial Park Conservancy renovations are innovative

Park of the future

Memorial Park is undergoing a huge transformation that is mixing a little bit of old with the new.

The Memorial Park Master Plan includes adding breathtaking new projects — like water features, a new athletic complex, and more — as well as conservation efforts that restore parts of the land that were native coastal prairie. The project is a collaborative effort between Memorial Park Conservancy, Uptown Houston TIRZ, and Houston Parks and Recreation Department to redevelop the 1,500-acre park.

The Master Plan is set to deliver a series of projects ahead of 2028, and there are a few initiatives that are innovative and different from other urban parks' transformations, notes MPC's president and CEO Shellye Arnold.

The Land Bridge

A big part of Memorial Park's transformation is restoring the park to native species and ecosystems.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," Arnold says. "This serves important stormwater purposes."

In order to connect two native coastal prairie lands on either side of Memorial Drive, MPC is building a unique 30-foot-high land bridge the size of three-and-a-half football fields. The space will be large enough that you don't even realize you're standing over a busy street, Arnold says.

The prairies will serve an important purpose for rainwater collection — a growing need within the city of Houston.

"We're channeling [rainwater] into this prairie where some of it can be absorbed, cleansed, slowed down," says Arnold. "And then what doesn't get slowed down and absorbed can flow through the prairie [on the other side], which is even bigger."

The Land Bridge also serves another purpose that park goers have wanted, Arnold says: Connectivity.

"[They] want access across the Memorial Drive — [they] want to safe access, and so this is the response. It's a pretty bold and visionary response," Arnold says.

BioCycling

In 2011, a major drought decimated the park and areas saw losses of 50 to even 90 percent of the canopy of trees. MPC and its team saved what could be saved, and the rest is serving a new purpose to the park.

"We took the trees that we lost on the drought that people felt such a tremendous loss for and ground them all up, and they are in a biocycle in a two-acre area in the back of the park," Arnold says.

The soil created — some of which includes manure from the animals at the Houston Zoo — has already been used on some plants in the park, and Arnold says those plants are thriving.

"It's cool that those those trees are giving life to the park," Arnold says.

Invasive species of trees that are plucked from out of the park are also being ground up and used in the same way.

"There isn't anything this big like this in an urban park setting like this kind of recycling effort," she says.

The biocycling process is scalable too.

"We could open this up to other organizations," Arnold says. "It's so much better ecologically to take trees and grind them up and use it inside the space rather than haul them out to landfill way outside of town and dump them."

The benefit to the program is that MPC can retain some of the soil it produces for these other organizations and use it on site.

Biodiversity initiatives and research

When putting the plans in place, MPC and its partners called on 25 of the best ecologists, as well as 50 more park and other types of consultants specializing in everything from insects and wildlife to prairies and trees.

Just as the Land Bridge is creating new prairie space, other initiatives throughout the park will be focused on eliminating invasive species and bringing back the natural ecosystem of the park.

The Easter Glades project, which is set to deliver next year, will have a habitat for fish, and will not allow any fishing or boating. Carolyn White, conservation director at MPC, is working with the Texas Wildlife Association to bring in the right species of fish.

Arnold says that MPC works with other organizations in an innovative way to bring native plants into MPC, since the park has the space for these organizations to use to cultivate and propagate plants.

"They bring their native plants and they grow them with their volunteers, and they leave us a little bit here," Arnold says. "We could never buy enough native plants to go inside this park."

Houston researcher secures $1.7M to develop drug for aggressive form of breast cancer

cancer research

A University of Houston researcher has joined a $3.2 million effort to develop a new drug designed to attack a cancer-driving protein commonly found in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is one of the most difficult-to-treat forms of cancer and accounts for 10 percent to 15 percent of all breast cancer cases. The disease gets its name because tumors associated with it test negative for estrogen receptors, progesterone receptors and excess HER2 protein, making it difficult to target. Due to this, TNBC is often treated with general chemotherapy, which can come with negative side effects and drug resistance, according to UH.

UH College of Pharmacy research associate professor Wei Wang is developing a drug that can target the disease more specifically. The drug will target MDM2, a protein often overproduced in TNBC that also contributes to faster tumor growth.

Wang is working on a team led by Wei Li, director of the University of Tennessee Health Science Center College of Pharmacy’s Drug Discovery Center. She has received $1.7 million to support the research.

Wang and UH professor of pharmacology and toxicology Ruiwen Zhang have discovered a compound that can break down MDM2. In early laboratory models, the compound has shown the ability to shrink tumors.

Wang and Zhang will focus on understanding how the treatment works and monitoring its effectiveness in models that closely mirror human disease.

“We will study how the drug targets MDM2 and evaluate the most promising drug candidates to determine effective dosing, understand how the drug behaves in the body, compare it with existing treatments and assess early safety,” Wang said in a news release.

Li’s team at the University of Tennessee will be working on the chemistry and drug design end of the project.

“This work could lead to an entirely new class of therapies for triple-negative breast cancer,” Li added in the release. “We’re hopeful that by directly removing the MDM2 protein from cancer cells, we can help more patients respond to treatment regardless of their tumor type.”

NASA revamps Artemis moon landing program by modeling it after Apollo

To the moon

NASA is revamping its Artemis moon exploration program to make it more like the fast-paced Apollo program half a century ago, adding an extra practice flight before attempting a high-risk lunar landing with a crew in two years.

The overhaul in the flight lineup came just days after NASA’s new moon rocket returned to its hangar for more repairs, and a safety panel warned the space agency to scale back its overly ambitious goals for humanity’s first lunar landing since 1972.

Artemis II, a lunar fly-around by four astronauts, is off until at least April because of rocket problems.

The follow-up mission, Artemis III, had been targeting a landing near the moon’s south pole by another pair of astronauts in about three years. But with long gaps between flights and concern growing over the readiness of a lunar lander and moonwalking suits, NASA’s new administrator Jared Isaacman announced that mission would instead focus on launching a lunar lander into orbit around Earth in 2027 for docking practice by astronauts flying in an Orion capsule.

The new plan calls for a moon landing — potentially even two moon landings — by astronauts in 2028.

“Everybody agrees. This is the only way forward,” Isaacman said.

The hydrogen fuel leaks and helium flow problems that struck the Space Launch System rocket on the pad at NASA's Kennedy Space Center in February also plagued the first Artemis test flight without a crew in 2022.

Another three-year gap was looming between Artemis II and the moon landing by astronauts as originally envisioned, Isaacman said.

Isaacman stressed that “it should be incredibly obvious” that three years between flights is unacceptable. He'd like to get it down to one year or even less.

Isaacman, a tech billionaire who bought his own trips to orbit and performed the world’s first private spacewalk, took the helm at NASA in December.

During NASA’s storied Apollo program, he said, astronauts’ first flight to the moon was followed by two more missions before Neil Armstrong and Buzz Aldrin landed on the moon. What's more, he added, the Apollo moonshots followed one another in quick succession, just as the earlier Projects Mercury and Gemini had rapid flight rates, sometimes coming just a few months apart.

Twenty-four Apollo astronauts flew to the moon from 1968 through 1972, with 12 of them landing.

“No one at NASA forgot their history books. They knew how to do this," Isaacman said. “Now we're putting it in action.”

To pick up the pace and reduce risk, NASA will standardize its Space Launch System rockets moving forward, Isaacman said. These are the massive rockets that will launch astronauts to the moon aboard Orion capsules. At the same time, Elon Musk's SpaceX and Jeff Bezos' Blue Origin are speeding up their work on the landers needed to get the astronauts from lunar orbit down to the surface.

Isaacman said next year will see an Orion crew rendezvousing in orbit around Earth with SpaceX's Starship, Blue Origin's Blue Moon or both landers. It's similar to the methodical approach that worked so well during Apollo in the late 1960s, he noted. Apollo 8, astronauts' first flight to the moon, was followed by two more missions before Armstrong and Aldrin aimed for the lunar surface.

“We should be getting back to basics and doing what we know works,” he said.

The Aerospace Safety Advisory Panel recommended that NASA revise its objectives for Artemis III “given the demanding mission goals.” It’s urgent the space agency do that, the panel said, if the United States hopes to safely return astronauts to the moon. Isaacman said the revised Artemis flight plan addresses the panel's concerns and is supported by industry and the Trump administration.
