Cafeteria worker honored by students By Anthony Antoine | April 6, 2021 at 7:55 PM EDT - Updated April 6 at 7:55 PM
PETERSBURG, Va. (WWBT) - The cafeteria manager at St. Joseph Catholic School in Petersburg is one of a kind. For decades sheâs made delicious meals for the entire school, all by herself.
Now, Mrs. Mann is getting a well-deserved thank you from some of the students who love her most. It started with love letters from a group of 6th-grade students, with gratitude baked right in.
âShe has a positive attitude even though she has to work so much,â says 6th grader Dylan Shah.
Alabama Power experts helping survey for rare species

Alabama Power is working with a number of partners to protect and grow populations of species such as the trispot darter, the gopher tortoise and the Black Warrior waterdog. (contributed)
As winter wanes and spring approaches, Alabama Power biologists are helping environmental partners with field work aimed at protecting rare species around the state.
Recent work has varied – from an ongoing search in east Alabama for an elusive, tiny fish, to gathering genetic material related to a rare salamander in the Black Warrior River Basin, to seeking out the underground homes of a protected tortoise in southeast Alabama.

It is not the glistening metal humanoid typically evoked by the word
robot. Instead, “PancakeBot,” as it’s endearingly known, is a small cylindrical thing, 15 centimeters long, reminiscent of a blood-pressure cuff. It’s lying on a flat wooden plank. You can tell it’s switched on when a silicone bladder where the cylinder meets the wood fills with air, like the inflation of a toad’s throat. The cylinder rocks unevenly a few times until it rolls forward a smidgen. Another bladder inflates. The cylinder rocks again, rolls, gets a little farther.
The process continues until the robot reaches a 14-degree slope. Here, the cylinder deflates into a flat rectangle. Then it begins its ascent inchworm-style, arching up, then flattening out, arching then flattening.

Stretchable electronic circuits are critical for soft robotics, wearable technologies, and biomedical applications. The current ways of making them, though, have limited their potential.
A team of researchers in the Yale lab of Rebecca Kramer-Bottiglio, the John J. Lee Assistant Professor of Mechanical Engineering & Materials Science, has developed a material and fabrication process that can rapidly make these devices stretchier, more durable, and closer to being ready for mass manufacturing. The results are published in the journal Nature Materials.
One of the biggest challenges for this area of electronics is to reliably connect stretchable conductors with the rigid materials used in commercially available electronics components, such as resistors, capacitors, and light-emitting diodes (LEDs).
