Is all research essential? Nope. Miguel Tovar/University of Houston

Many researchers have begun to work from home due to the novel COVID-19 pandemic, and only essential personnel are allowed to work on university campuses. For a researcher, what is considered "essential personnel"? Isn't all research essential to the workings of a public research university?

In a word, no.

As much as one would like to believe their respective job is of the utmost importance to human existence, certain mitigating factors can overrule that sensibility – and the definition of the word "essential" – in a moment's time. According to an article in Inside Higher Education, a Ph.D. candidate researching diabetes at the University of Toronto said, "There is no single experiment or laboratory activity that is more important than saving the life of even a single individual in the community."

Your university or institution may not have closed completely, yet it is safe to suspect that you have been asked to complete most of your work remotely. With most counties in the nation declaring a shelter in place order, researchers who have been required to "ramp down" lab activities may be feeling extreme disappointment and even panic.

Allowances and exceptions for federally funded research

The NSF has extended deadlines for some applications and reports. For instance, it has extended the dates of all annual project reports due between March 1 and April 30 by 30 days. In addition, the charge of costs or fees that have been incurred due to COVID-19 can be negotiated, as long as there is proper documentation and the result is not a shortage of funds to eventually carry out the project.

The NIH released NOT-OD-20-086 on March 12, 2020 to alert the research community of certain flexibilities which apply to NIH applicants and recipients. Some of these include pre-award costs, extension of required reporting, prior approval waivers and expenditure of award funds – especially involving travel. There are other exceptions being made, including allowing salaries to be charged against grant monies in some instances.

So, you have to go to campus

If you are a researcher who ensures the continuity of key operations, such as an animal care operations worker, there are several things you can do to keep yourself and your colleagues safe, which will come as no

surprise:

  1. Very few researchers are allowed on campus. If you are working on campus, keep 6 feet away from your co-workers. There should be a greatly reduced number of researchers in the lab or facility at any given time.
  2. Wash your hands. Follow all environmental safety and hazardous material rules to a tee.
  3. Be careful when getting deliveries and regularly clean your workspace.
  4. Research the many funding opportunities that are available to contribute to the solution of COVID-19 related issues.

Just breathe…it’s going to be okay

If this pandemic has taught us anything, it is that an emergency plan is the best bet for staving off panic and flowing as seamlessly as possible into a remote working situation. As always, safety is goal one and this situation's trajectory is causing safety concerns to escalate. Your research will ramp up again, make no mistake, although for the time being it may have fallen victim to this outbreak. If you stay in close adherence to policies put forth by your institution and you keep your sponsor abreast of your next steps, all will work out in the end.

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.”
