Unusual material that contracts when heated is giving up its secrets to physicists
Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous temperature range over which it exhibits so-called “negative thermal expansion,” contracting as it heats up and expanding as it cools, and because it does so…

A puzzle posed by black-headed ducks yields to persistent biologists
Some 100 species of birds are what scientists call “obligate brood parasites”–instead of building nests and raising their own young, they lay their eggs in the nests of other species and let those birds do the hard work of parenting for them. The black-headed duck of South America is one of these, but it stands…

Order of Species Loss has Important Biodiversity Consequences, Grassland Study Reveals
In a study that mimicked the natural order of species loss in a grassland ecosystem, researchers found that declining biodiversity greatly reduced resistance to invasive species and that the presence of even small numbers of rare species had profound functional effects. The results, which appear in the November 12 issue of Science, have important implications…

Laboratory test of evolutionary theory confirms the importance of connections between populations
Researchers studying the evolutionary dynamics of bacteria and viruses in bubbling glass tubes have confirmed an evolutionary theory of central importance to ecologists studying more familiar flora and fauna in the wild. The theory predicts how the movement of individuals between different populations of a species influences evolutionary change in those populations, particularly with respect…

UCSC Arboretum, now in its 40th year, holds annual fall plant sale on Saturday, October 9
In the fall of 1964, one year before the first class of students entered the University of California, Santa Cruz, the first trees were planted in the UCSC Arboretum. Some of those plantings have since grown into the graceful trees of the Eucalyptus Grove, where the Arboretum’s plant sales are now held. And the Arboretum…
