Sani nudge, a graduate of the TMCx healthcare accelerator's nineth cohort at Houston's Texas Medical Center, is getting a significant nudge from a new collaboration with a social-impact organization based in California.

Among more than 1,000 startups that were considered, Copenhagen, Denmark-based Sani nudge was chosen as one of nine participants in the Mistletoe Research Fellowship Startup Collaboration Program, sponsored by the Mistletoe Foundation. Three dozen researchers from seven universities also are taking part in the program.

Fresh off a $1.2 million funding round, Sani nudge's technology is an automated monitoring system aimed at helping healthcare workers bolster hygiene compliance and processes through insights from data and a feature that "nudges" healthcare workers to practice proper hand hygiene. Sani nudge created the technology in conjunction with Bispebjerg Hospital and Aarhus University Hospital, both in Denmark.

In the Mistletoe program, representatives of Sani nudge will work alongside four American researchers to improve the startup's technology, thereby providing hospitals with better data and tapping the researchers' expertise in engineering and robotics to come up with related healthcare platforms. Sani nudge employs 13 people in the U.S., Denmark, and Poland.

During tests in healthcare settings, the use of Sani nudge has resulted in a jump in hand hygiene compliance of as much as 200 percent and a reduction in infections of at least 29 percent, the company says. Several hospitals in Scandinavia are using the Sani nudge system.

Theis Jensen, CEO of Sani nudge, and Dr. Marco Bo Hansen, the chief customer officer, became acquainted with Mistletoe when they met Mark Castleman — a partner at the Mistletoe Inc. global-impact investment fund — during a startup and innovation tour of Texas organized by Capital Factory, a startup accelerator with locations in Houston, Austin, and Dallas.

The three men soon found common ground in a shared vision for reducing hospital-acquired infections and combating resistance to antibiotics. Both are costly, potentially fatal problems.

At any given time, 1 in 25 patients in the U.S. are fighting hospital-acquired infections, the U.S. Department of Health and Human Services says. "These infections lead to the loss of tens of thousands of lives," according to the department, "and cost the U.S. healthcare system billions of dollars each year."

Meanwhile, more than 2 million people in the U.S. are infected each year with antibiotic-resistant bacteria, and at least 23,000 people die as a result, according to the U.S. Centers for Disease Control and Prevention (CDC).

Sani nudge's participation in the Mistletoe program kicked off July 31 and August 1 at a workshop in Tokyo. For the next nine months, the Sani nudge group — led by Rebekah Alexander, the startup's in-house data expert — will team up with its four assigned researchers to advance the startup's wireless technology.

The researchers "will work with us over the following academic year to help us take the Sani nudge solution to the next level and enable hospitals to get even more detailed hand hygiene information that can eliminate hospital-acquired infections," Sani nudge wrote on its blog.

In June 2020, the next-level Sani nudge technology is scheduled to be presented to potential investors and academic researchers in Silicon Valley. Sani nudge says Mistletoe effort will strengthen its ties to the U.S. market and the academic research community.

"There are many opportunities within healthcare IoT that can help both patients and hospitals, and our system is designed to embrace these opportunities," Hansen says.

Hansen, a physician, says he'll be vigilantly advocating that his Sani nudge colleagues and the Mistletoe researchers keep hospital patients and staff in mind as Sani nudge moves forward with its innovations.

"We have to make sure that our solutions always generate value to the end users and can easily be used by the clinicians, infection preventionists, and hospital managers," he says.

Houston team’s discovery brings solid-state batteries closer to EV use

A Better Battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

University of Houston archaeologists make history with Mayan tomb discovery

History in the Making

Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

"Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

“The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.
