Hunger impacts over 800 million people worldwide, leaving nearly 10 percent of the population suffering from chronic undernourishment. The distressing reality of food shortages co-exists in a world where 1.3 billion tons of food — nearly a third of what's produced — is wasted each year, according to the Food and Agriculture Organization of the United Nations. Rice University's scientific research team's latest discovery takes a crack at ending food shortages and improving sustainability with a common kitchen necessity: eggs.

The discovery of egg-based coating is promising to researchers, as it manages to both prolong produce shelf-life by double while impacting the environment.

"We are reducing the cost, and at the same time we are reducing the waste," says Muhammad M. Rahman, a research scientist at Rice University. "One in every eight people are hungry...on the other side, 33 percent of food is wasted."

It's no secret that overflowing landfills contribute to the climate crisis, piling high with food waste each year. While the United States produces more than seven billion eggs a year, manufacturers reject 3 percent of them. The Rice University researchers estimate that more than 200 million eggs end up in U.S. landfills annually.

According to the Environmental Protection Agency, half of all landfill gas is methane, a hazardous greenhouse gas that contributes to detrimental climate change. Landfills are the third-largest contributor to methane emissions in the country, riding the coattails of agriculture and the energy industry.

COVID-19 has upended supply chains across the nation, and in recent months food waste has become an even more pressing issue. The disruptions of consumer purchasing habits and the indefinite closures of theme parks and select restaurants put a burden on farmers who planned for larger harvests and restaurants unsure of how to adjust. With more Americans cooking at home, panic-buying from grocery stores is also playing a role in accumulating waste.

To understand the challenges of the food industry, it's important to acknowledge the biggest menace to the supply chain: perishability. Fruits and vegetables only last a few days once arriving in grocery stores due to culprits like dehydration, texture deterioration, respiration and microbial growth. Rice University researchers sought to create a coating that addresses each of these issues in a natural, cost-effective way.

Brown School of Engineering materials scientist, Pulickei Ajayan, and his colleagues, were looking for a protein to fight issues like food waste. Rahman, a researcher in Ajayan's lab, received his Ph.D. from Cornell University studying the structure-property relationship in green nanocomposites. He and his fellow researchers found that egg whites were a suitable protein that wouldn't alter the biological and physiological properties of fruit. The study published in Advanced Materials took one year and three months to complete.

According to Rahman, the egg-based coating is non-toxic, biodegradable and healthier than other alternatives on the market. Wax is one common method of fruit preservation that can result in adverse effects on gut cells and the body over time.

"Long-term consumption of wax is not actually good and is very bad for your health," says Dr. Rahman. After wax is consumed, gut cells fragment the preservatives in wax to ions. This process can have a negative impact on "membrane disruption, essential metabolite inhibition, energy drainage to restore homeostasis, and reductions in body-weight gain," according to the research abstract.

Preservation efforts like wax, modified atmospheric packaging and paraffin-based active coatings are not only more expensive and less healthy, but they also alter the taste and look of fruits.

"Reducing food shortages in ways that don't involve genetic modification, inedible coatings or chemical additives is important for sustainable living," Ajayan states in a press release.

The magic of preservation is all in the ingredients. Rice University's edible coating is mostly made from household items. Seventy percent of the egg coating is made from egg whites and yolk. Cellulose nanocrystals, a biopolymer from wood, are mixed with the egg to create a gas barrier and keep the produce from shriveling. To add elasticity to the brittle poly-albumen (egg), glycerol helps make the coating flexible. Finally, curcumin—an extract found in turmeric—works as an antibacterial to reduce the microbial growth and preserve the fruit's freshness.

The experiment was done by dipping strawberries, avocados, papayas and bananas in the multifunctional coating and comparing them with uncoated fruits. Observation during the decaying process showed that the coated fruits had about double the shelf-life of their non-coated counterparts.

For people with egg allergies, the coating can be removed simply by rinsing the produce in water. Rice University researchers are also beginning to test plant-based proteins for vegan consumers.

For its first iteration, Rahman finds that the coating shows "optimistic results" and "potential" for the future of food preservation.

"These are already very green materials. In the next phase, we are trying to optimize this coating and extend the samples from fruits to vegetables and eggs," says Rahman.

Researchers will also work to test a spray protein, making it easier for both commercial providers as well as consumers looking for an at-home coating option. From a lab in Rice University to a potential shelf life in stores, the innovation of food coating is just beginning.

Texas Space Commission launches, Houston execs named to leadership

future of space

Governor Greg Abbott announced the Texas Space Commission, naming its inaugural board of directors and Texas Aerospace Research and Space Economy Consortium Executive Committee.

The announcement came at NASA's Johnson Space Center, and the governor was joined by Speaker Dade Phelan, Representative Greg Bonnen, Representative Dennis Paul, NASA's Johnson Space Center Director Vanessa Wyche, and various aerospace industry leaders.

According to a news release, the Texas Space Commission will aim to strengthen commercial, civil, and military aerospace activity by promoting innovation in space exploration and commercial aerospace opportunities, which will include the integration of space, aeronautics, and aviation industries as part of the Texas economy.

The Commission will be governed by a nine-member board of directors. The board will also administer the legislatively created Space Exploration and Aeronautics Research Fund to provide grants to eligible entities.

“Texas is home to trailblazers and innovators, and we have a rich history of traversing the final frontier: space,” Lieutenant Governor Dan Patrick says in a news release. “Texas is and will continue to be the epicenter for the space industry across the globe, and I have total confidence that my appointees to the Texas Space Commission Board of Directors and the Texas Aerospace Research and Space Economy Consortium Executive Committee will ensure the Texas space industry remains an international powerhouse for cutting-edge space innovation.”

TARSEC will independently identify research opportunities that will assist the state’s position in aeronautics research and development, astronautics, space commercialization, and space flight infrastructure. It also plans to fuel the integration of space, aeronautics, astronautics, and aviation industries into the Texas economy. TARSEC will be governed by an executive committee and will be composed of representatives of each higher education institution in the state.

“Since its very inception, NASA’s Johnson Space Center has been home to manned spaceflight, propelling Texas as the national leader in the U.S. space program,” Abbott says during the announcement. “It was at Rice University where President John F. Kennedy announced that the U.S. would put a man on the moon—not because it was easy, but because it was hard.

"Now, with the Texas Space Commission, our great state will have a group that is responsible for dreaming and achieving the next generation of human exploration in space," he continues. "Texas is the launchpad for Mars, innovating the technology that will colonize humanity’s first new planet. As we look into the future of space, one thing is clear: those who reach for the stars do so from the great state of Texas. I look forward to working with the Texas Space Commission, and I thank the Texas Legislature for partnering with industry and higher education institutions to secure the future of Texas' robust space industry."

The Houston-area board of directors appointees included:

  • Gwen Griffin, chief executive officer of the Griffin Communications Group
  • John Shannon, vice president of Exploration Systems at the Boeing Company
  • Sarah "Sassie" Duggleby, co-founder and CEO of Venus Aerospace
  • Kirk Shireman, vice president of Lunar Exploration Campaigns at Lockheed Martin

City of Houston approves $13M for new security tech at renovated IAH​ terminal

hi, tech

A new terminal currently under construction at George Bush Intercontinental Airport just got the green light for new security technology.

This week, Houston City Council unanimously approved the funding for the new Mickey Leland International Terminal's security equipment. The Mickey Leland International Terminal Project is part of the $1.43 billion IAH Terminal Redevelopment Program, or ITRP, which is expected to be completed by early next year.

This new IAH International Terminal will feature an International Central Processor, or ICP, with state-of-the-art technology in a 17-lane security checkpoint — among the largest in the country — as well as ticket counters and baggage claim.

“Houston Airports strives to get passengers through TSA Security in 20 minutes or less. Today, we meet that goal at Bush Airport more than 90 percent of the time,” Jim Szczesniak, director of aviation for Houston Airports, says in a news release. “This investment in innovative technology will enhance our efficiency and ensure that our passengers have a world-class experience each time they visit our airports.”

The funding approval came from two ordinances, and the first one appropriates $11.8 million from the Airports Improvement Fund to buy, service, install, and train staff on nine new automated screening lanes, called Scarabee Checkpoint Property Screening Systems, or CPSS.

Per the news release, each of these CCPS automated lanes "is capable of screening more than 100 additional people and bags/hour than existing equipment used today." Currently, Terminal D's TSA is using eight CPSS Lanes, so the additional nine lanes will bring the total to 17 lanes of security.

The other appropriates another $1.2 million from the Airports Improvement Fund to buy, install, maintain, and train staff on six new Advanced Imaging Technology Quick Personnel Security Scanners.

The new scanners, which don't require the traveler to raise their arms, "is capable of screening more than 100 additional people/hour than existing equipment used today," per the release.

“These new security screening machines are faster, have fewer false alarms and have improved detection rates, which creates a safer experience for our passengers and airlines,” Federal Security Director for TSA at IAH Juan Sanchez adds.

Texas has the 5th highest health care costs in the nation, Forbes says

dollar signs

A new Forbes Advisor study shedding light on Americans' top financial worries has revealed Texas has the fifth highest health care costs in the nation.

Forbes Advisor's annual report compared all 50 states and Washington, D.C. across nine different metrics to determine which states have the most and least expensive health care costs in 2024.

Factors include the average annual deductibles and premiums for employees using single and family coverage through employer-provided health insurances and the percentage of adults who chose not to see a health care provider due to costs within the last year, among others. Each state was ranked based on its score out of a total 100 possible points.

Texas was No. 5 with a score of 91.38 points. North Carolina was No. 1, followed in order by South Dakota, Nebraska, and Florida.

According to Forbes, out-of-state families considering a move to the Lone Star State should be aware of the state's troubling statistics when it comes to family health care. More specifically, nearly 15 percent of Texas children had families who struggled to pay for their medical bills in the past 12 months, the highest percentage in the nation.

Furthermore, Texans have the highest likelihood in the U.S. to skip seeing a doctor because of cost. The report showed 16 percent of Texas adults chose not to see a doctor in the past 12 months due to the cost of health care.

"Unexpected medical bills and the cost of health care services are the top two financial worries for Americans this year, according to a recent KFF health tracking poll," the report said. "These financial fears have real-world consequences. The high cost of healthcare is leading some Americans to make tough choices—often at the expense of their health."

In the category for the percentage of adults who reported 14 or more "mentally unhealthy" days out of a month, who could not seek health care services due to cost, Texas ranked No. 3 in the U.S. with 31.5 percent of adults experiencing these issues.

The report also highlighted the crystal clear inequality in the distribution of health care costs across the U.S.

"In some states, residents face much steeper health care expenses, including higher premiums and deductibles, which make them more likely to delay medical care due to costs," the report said.

For example, Texas' average annual premiums for both plus-one health insurance coverage ($4,626, according to the study) and family coverage ($7,051.33) through employer-provided policies was the No. 4-highest in the nation.

Elsewhere in the U.S.

The state with the most expensive health care costs is North Carolina, with a score of 100 points. 27 percent of adults in North Carolina reported struggling with their mental health who could not seek a doctor due to cost, and 11.3 percent of all adults in the state chose not to see a doctor within the last 12 months because of costs.

Hawaii (No. 50) is the state with the least expensive health care costs, according to Forbes. Hawaii had the lowest percentages of adults struggling with mental health (11.6 percent) and adults who chose not to see a doctor within the last year (5.7 percent). The average annual premium for employees in Hawaii using a family coverage plan through employer-provided health insurance is $5,373.67, and the average annual deductible for the same family coverage plan is $3,115.

The top 10 states with the most expensive health care are:

  • No. 1 – North Carolina
  • No. 2 – South Dakota
  • No. 3 – Nebraska
  • No. 4 – Florida
  • No. 5 – Texas
  • No. 6 – South Carolina
  • No. 7 – Arizona
  • No. 8 – Georgia
  • No. 9 – New Hampshire
  • No. 10 – Louisiana
