When the coronavirus forced the closure of restaurants, stores, and community centers, it disproportionally affected the health of a population of people: The homeless.

Homeless individuals are acutely vulnerable amid the public health and hygiene concerns due to the coronavirus pandemic, says Houstonian Nijalon Dunn. These communities of people have been left without immediate access to soap and clean water, especially with the closure of local businesses whose restrooms sometimes served as individuals' only sources of clean water.

"[Local businesses are] where people were able to use the restroom, wash their hands and have access to soap and water," Dunn says. "Take public restrooms away, now you have an increase in public urination and people using the restroom outside. Not only that, but people aren't washing their hands because of a lack of education and awareness about social distancing and hygiene practices."

Observing this effect of the virus, a group of Houstonians pulled together their skills and resources to provide handwashing stations across the city for Houston's homeless population.

Rise Houston Church, a local organization servicing inner-city Houston, is behind the initiative. Eager to help the community during the coronavirus pandemic, Rise Houston's pastor Stan DePue proposed the idea of building and distributing handwashing stations that would provide clean water and soap to homeless communities.

Dunn paired used his photography and filmmaking skills for a great cause when partnering with Rise Houston: Clean Hands. Dunn, a member of Rise Houston and founder of Black Visa Creative, a Houston company specializing in creative and commercial portraits that help small businesses tell their stories, knew that he could elevate DePue's project's reach and awareness through photojournalism.

"For us to have the impact and raise the support we needed, I knew that we needed to be documenting this [project]. So [Stan] and I partnered," Dunn says.

The idea evolved into an initiative with 10 sinks deployed across the city of Houston. According to Rise Houston's website, the sinks cost $300 to install. The church is looking for support in funding and maintaining the sinks — more information on giving back is available online.

DePue and his congregation are running the project's operation and physically constructing the sinks, and Dunn overseeing the project's documentation and awareness.

"We've been working with boots on the ground, creating partnerships so that we have strategic locations [for sinks] and know that they'll serve the best purpose in the areas where we place them," Dunn says.

After sink locations were identified across Houston, Rise Houston: Clean Hands volunteers delivered and set up the sinks on-site, each complete with a seven-gallon water tank, a water dispenser foot pump, soap and paper towel dispensers, trash bags, and signs that encourage the six-feet-apart social distancing rule.

"In order to stop the spread of coronavirus and flatten the curve, we needed to bring innovation to the way we serve our homeless brothers and sisters during this time," Dunn says.

A striking observation from Dunn's experience with this project, and the individuals he has worked and conversed with, has been how grateful people have been to learn about and be exposed to hygienic resources and practices, Dunn says.

"One of the greatest assets of the storyteller is knowing when to put the camera down. Some of the places we go to are some of the most vulnerable places in the city," Dunn says. "When we go into these homeless camps, I need to know when to put the camera down and live and exist with the person I talk to."

Through these interpersonal encounters, the teamwork of Rise Houston: Clean Hands volunteers and Dunn's innovative approach to communicating about this issue, the initiative has been able to sustain maintenance of the sinks and further spread hygienic awareness to Houstonians.

Houston food giant Sysco to acquire competitor in $29 billion deal

Mergers & Acquisitions

Sysco, the nation's largest food distributor, will acquire supplier Restaurant Depot in a deal worth more than $29 billion.

The acquisition would create a closer link between Sysco and its customers that right now turn to Restaurant Depot for supplies needed quickly in an industry segment known as “cash-and-carry wholesale.”

Sysco, based in Houston, serves more than 700,000 restaurants, hospitals, schools, and hotels, supplying them with everything from butter and eggs to napkins. Those goods are typically acquired ahead of time based on how much traffic that restaurants typically see.

Restaurant Depot offers memberships to mom-and-pop restaurants and other businesses, giving them access to warehouses stocked with supplies for when they run short of what they've purchased from suppliers like Sysco.

It is a fast growing and high-margin segment that will likely mean thousands of restaurants will rely increasingly on Sysco for day-to-day needs.

Restaurant Depot shareholders will receive $21.6 billion in cash and 91.5 million Sysco shares. Based on Sysco’s closing share price of $81.80 as of March 27, 2026, the deal has an enterprise value of about $29.1 billion.

Restaurant Depot was founded in Brooklyn in 1976. The family-run business then known as Jetro Restaurant Depot, has become the nation's largest cash-and-carry wholesaler.

The boards of both companies have approved the acquisition, but it would still need regulatory approval.

Shares of Sysco Corp. tumbled 13% Monday to $71.26, an initial decline some industry analysts expected given the cost of the deal.

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”
