Possessive puppies: Jealous behaviors in dogs
Emotion researchers have been arguing for years whether jealousy requires complex cognition. And some scientists have even said that jealousy is an entirely social construct — not seen in all human cultures and not fundamental or hard-wired in the same ways that fear and anger are.
A current study by UC San Diego professor Christine Harris is the first experimental test of jealous behaviors in dogs. The findings support the view that there may be a more basic form of jealousy, which evolved to protect social bonds from interlopers.
“Our study suggests not only that dogs do engage in what appear to be jealous behaviors but also that they were seeking to break up the connection between the owner and a seeming rival,” Harris said. “We can’t really speak to the dogs’ subjective experiences, of course, but it looks as though they were motivated to protect an important social relationship.”

How small can a laser get? ucsandiego researchers are studying new ways to scale them to microscopic levels in order to use them on microchips. These nanolasers will allow computers to send much bigger amounts of data in a more energy efficient way.
After producing a story about UC San Diego materials scientists coming up with a novel method inspired by the narwhal’s long, spiral tooth, it was fun to see our local barista wearing a shirt emblazoned with the arctic whale.
Materials scientists at UC San Diego’s Jacobs School of Engineering have looked to the narwhal for bio-inspiration. This arctic whale’s spiraling tusk, which is a long tooth that juts out of its mouth, led researchers to invent a method called magnetic freeze casting. The result? Bio-inspired type bone. We’ll soon feature an interview with one of the researchers, Joanna McKittrick, about this new invention.
Bio-inspired materials essentially use Mother Nature as a guide. Materials scientist Joanna McKittrick of the University of California, San Diego’s Jacobs School of Engineering is interested in making new materials that have enhanced mechanical properties.
"And one way to do that is to look at how Mother Nature has created structures such as antlers or horns or porcupine quills, looking at feathers for example for lightweight structures. Same thing with the porcupine quills. Antlers and animal horns are impact resistant so they can absorb a lot of energy before they break. And that would be good for making bumpers or kneepads or helmets. "
Recently, McKittrick’s team has been inspired by the seahorse.
"The surprising thing about the seahorse is its tail. It can wrap and it can bend, it can curl up, but it can also curl to the sides. So it is very flexible and we thought wow that would make a good probe; that would make a good robot arm."
We really enjoyed our conversation with Drs. Albert Lin & Eliah Aronoff-Spencer at UC San Diego about their citizen sensor project that may revolutionize global health and environmental monitoring – especially in remote and undeveloped areas of the world. And yes, their device does bring to mind Spock and his trusty tricorder.
We always appreciate getting an inside look at some of the tools used to conduct ucresearch. In this case, we were visiting a materials science lab at the UC San Diego Jacobs School of Engineering and came across this lab-built vacuum chamber with an attached electron gun. It’s used to measure cathodoluminescent properties of materials, usually for flat panel display applications.
