Astronomers observe a supernovae within hours of the explosion
For the first time ever, scientists have gathered direct evidence of a rare Wolf-Rayet star being linked to a specific type of stellar explosion known as a Type IIb supernova. Peter Nugent of the Lawrence Berkeley National Laboratory talks to us about this star:
We never had a nearby example where we could say, ‘oh this star became this supernova.’ So this was the first time we can directly point to it and say because we heated up this wind and because we could see the wind that looks just like a Wolf-Rayet star, we know that the Wolf-Rayet star blew up and then became this type of supernova.
Nugent says they caught this star – a whopping 360 million light years away – just a few hours after it exploded.
Anthropologists, linguists and enthnographers were among the first to adopt sound recording as a tool for research. Physicist Carl Haber of the Lawrence Berkeley National Laboratory developed technology to restore and preserve historic sound recordings, including California Native American languages, songs and stories that were recorded in the early 1900s on wax cylinders.
If you’re one of the nation’s experts on spiders and the properties of their silk, you best not have a hint of arachnophobia. Fortunately for us UC Riverside’s evolutionary biologist Cheryl Hayashi does not have this problem.
We had the pleasure of interviewing Hayashi in the past and she told us then that one of the spider silk proteins they genetically sequenced dated back about 250 million years.
That’s a really long period of time. I mean, we’re going back to the Mesozoic, when dinosaurs are walking around. And so this is a long time for these sequences to be conserved. And to us, that argues that these regions of the sequence are probably very important for the functioning of spider silks.
Hayashi explained that there’s lots of interest in creating synthetic spider silks.
Spider silk is very strong and very tough. It actually surpasses a lot of the common man-made materials. It’s stronger than high tensile steel and has a toughness that is greater than Kevlar. So there’s a lot of interest in being able to mass produce spider silk.
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.
At UC Santa Cruz, the OpenLab Network brings artists and scientists together in an effort to better illustrate complex research and engage the public.
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.
Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?”

You just never know who you’re going to meet ….
At a restaurant about a year ago, we happened to be seated next to a like-minded foodie and began a conversation about what was on our plates. Turns out that person was UCLA’s Amy Rowat, an integrated biologist who has been making a lot of waves with her innovative scienceandfood program. Our ucresearch production team made sure to look her up during a SoCal trip.
