Astronomers capture a dwarf galaxy being torn apart in the dark matter halo of a massive galaxy
For the first time, astronomers have found direct evidence of a phenomenon long thought to play an important role in the formation of giant galaxies: the ongoing disruption of a small galaxy as it orbits within the dark matter halo of a much larger galaxy. Images from the Hubble Space Telescope, confirmed by detailed observations…

Coastal upwelling in the California Current was weaker 6,000 years ago than today, according to new studies
The California Current is a major influence on the climate of western North America and on the productivity of both terrestrial and marine ecosystems along the West Coast. But 6,000 years ago, the California Current wasn’t quite what it is today, according to a team of researchers at the University of California, Santa Cruz. New…

UCSC professor seeks to reconnect mathematics to its intellectual roots
Anthony Tromba has loved mathematics since he was a child, and it bothers him that the field seems to be losing its appeal to students. Tromba, professor and chair of mathematics at the University of California, Santa Cruz, said that when he was an undergraduate in the 1960s there were nearly six times as many…

Astronomers reveal the first detailed maps of galaxy distribution in the early universe
Peering back in time more than 7 billion years, a team of astronomers using a powerful new spectrograph at the W. M. Keck Observatory in Hawaii has obtained the first maps showing the distribution of galaxies in the early universe. The maps show the clustering of galaxies into a variety of large-scale structures, including long…

Study shows lead-based paint is poisoning albatross chicks at Midway Atoll National Wildlife Refuge
Lead-based paint from deteriorating buildings still poses a hazard to wildlife on Midway Atoll, despite extensive environmental remediation efforts undertaken as part of the conversion of the site from a military base to a national wildlife refuge. A new study by researchers at the University of California, Santa Cruz, shows that Laysan albatross chicks in…

Cooperation between unrelated male lizards adds a new wrinkle to evolutionary theory
Blue-throated lizards that help each other achieve reproductive success are also helping scientists understand how social cooperation evolved. Most examples of cooperative behavior in animals involve cooperation between genetically related individuals, which is explained by the theory of “kin selection.” Now, researchers have described an example of cooperation between genetically similar but unrelated members of…

‘Deep Store’ project at UCSC attracts government and industry funding to address data storage problems
Computer scientists at the University of California, Santa Cruz, are developing a new approach to online “deep storage” of digital data that promises to have many advantages over traditional backup and archival storage methods. The UCSC Deep Store project has been awarded a $205,000 grant from the National Science Foundation, and has received significant gift…

UCSC engineer receives major grant to improve engine efficiency using nanotechnology
Researchers at the University of California, Santa Cruz, are leading a collaborative effort to develop new technology that could increase the efficiency of internal combustion engines by converting waste heat into electric current. The project will use nanoscale engineering of materials to develop efficient technology for direct conversion of thermal energy to electric energy. It…

Massive tsunami sweeps Atlantic Coast in asteroid impact scenario for March 16, 2880
If an asteroid crashes into the Earth, it is likely to splash down somewhere in the oceans that cover 70 percent of the planet’s surface. Huge tsunami waves, spreading out from the impact site like the ripples from a rock tossed into a pond, would inundate heavily populated coastal areas. A computer simulation of an…
