Research reveals Hawai‘i’s undersea volcano, Kama‘ehu, erupted five times in past 150 years

Research reveals Kama'ehu volcano in Hawaii has erupted five times in the past 150 years. The new study uses mass spectrometry to measure radium-226 in lava samples, revealing a frequency of eruptions around 30 years. This slower rate is linked to sluggish mantle upwelling on the margin of the Hawaiian plume.

Way cool: UVA professor developing ‘freeze ray’ technology for the Air Force

UVA professor Patrick Hopkins is developing a 'freeze ray' technology to cool electronics in spacecraft and high-altitude jets, which can't be cooled by nature due to the vacuum of space. The technology uses heat-generating plasma to create localized cooling, and has been granted $750,000 by the Air Force.
