In the not-too-distant future, a Texas company's 3-D printed homes will be popping up across the world for a fraction of the cost of traditional homes.

"It's our mission at ICON to reimagine the approach to homebuilding and construction and make affordable, dignified housing available to everyone throughout the world," says Jason Ballard, co-founder and CEO of Austin-based ICON LLC. "We're in the middle of a global housing crisis, and making old approaches a little better is not solving the problem."

The 3-D printed homes startup just raked in $9 million in seed funding from a host of investors, including Fort Worth-based homebuilding giant D.R. Horton; Vulcan Capital, a Seattle investment firm launched by Microsoft billionaire Paul Allen, who died October 15; Austin startup accelerator Capital Factory; Austin real estate developer Cielo Property Group; and San Francisco venture capital firm Oakhouse Partners, which is the lead investor.

At this point, ICON executives aren't sure when their homes will be popping up around town. However, Ballard tells CultureMap, "serious conversations" are underway about bringing these homes to Austin and other places around the world.

In March, ICON reaped tons of press when it unveiled a 350-square-foot 3-D home at SXSW — the first home of its kind to receive a construction permit in the U.S. At the time, ICON executives said the home — constructed of concrete and printed in less than 48 hours by 3-D printing robots — cost less than $10,000. By contrast, the median price in September 2018 of a single-family home in the Austin metro area was $302,250.

ICON's first batch of homes is planned for a project in impoverished El Salvador that's being developed in conjunction with New Story, a San Francisco nonprofit that seeks to eradicate homelessness. The first homes there are scheduled to be printed next year.

ICON is targeting a per-home cost of $4,000 in El Salvador. Relying on technology upgrades, ICON hopes to create each 3-D home in less than 24 hours.

"While prices to print homes will vary from country to country and state to state," Ballard says, "the big takeaway is that downloading and printing a home has the potential to cost half of standard construction costs."

Homes at the development in El Salvador will measure 600 to 800 square feet — around the size of a typical one-bedroom apartment. Eventually, ICON aims to print homes in the 1,500- to 2,000-square-foot range.

Among the advantages of 3-D printed homes cited by ICON are:

Speedy construction
No manual labor
Little generation of leftover construction materials
"Tremendous" design freedom

There's a positive environmental impact with this construction process as well.

"Conventional construction is slow, fragmented, wasteful, and has poor thermal properties that increase energy use, increase operating costs, and decrease comfort," Ballard says. "Also, conventional materials like drywall and particleboard are some of the least resilient materials ever invented."

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.

Houston doctor wins NIH grant to test virtual reality for ICU delirium

Virtual healing

Think of it like a reverse version of The Matrix. A person wakes up in a hospital bed and gets plugged into a virtual reality game world in order to heal.

While it may sound far-fetched, Dr. Hina Faisal, a Houston Methodist critical care specialist in the Department of Surgery, was recently awarded a $242,000 grant from the National Institute of Health to test the effects of VR games on patients coming out of major surgery in the intensive care unit (ICU).

The five-year study will focus on older patients using mental stimulation techniques to reduce incidences of delirium. The award comes courtesy of the National Institute on Aging K76 Paul B. Beeson Emerging Leaders Career Development Award in Aging.

“As the population of older adults continues to grow, the need for effective, scalable interventions to prevent postoperative complications like delirium is more important than ever,” Faisal said in a news release.

ICU delirium is a serious condition that can lead to major complications and even death. Roughly 87 percent of patients who undergo major surgery involving intubation will experience some form of delirium coming out of anesthesia. Causes can range from infection to drug reactions. While many cases are mild, prolonged ICU delirium may prevent a patient from following medical advice or even cause them to hurt themselves.

Using VR games to treat delirium is a rapidly emerging and exciting branch of medicine. Studies show that VR games can help promote mental activity, memory and cognitive function. However, the full benefits are currently unknown as studies have been hampered by small patient populations.

Faisal believes that half of all ICU delirium cases are preventable through VR treatment. Currently, a general lack of knowledge and resources has been holding back the advancement of the treatment.

Hopefully, the work of Faisal in one of the busiest medical cities in the world can alleviate that problem as she spends the next half-decade plugging patients into games to aid in their healing.
