Six Caltech Professors Awarded Sloan Research Fellowships

Six Caltech professors recently received Alfred P. Sloan Research Fellowships for 2003.

Antarctic landmarks named afterCaltech experts on glacier ice flow

Barclay Kamb and Hermann Engelhardt, longtime researchers on the workings of the Antarctic ice streams, have been honored by the American Advisory Committee on Antarctic Names (ACAN) with the renaming of two features near the gigantic Ross Ice Shelf, a Texas-sized mass of floating ice.


The Martian polar caps are almost entirelywater ice, Caltech research shows

Reporting in the February 14 issue of the journal Science, Caltech planetary science professor Andy Ingersoll and his graduate student, Shane Byrne, present evidence that the decades-old model of the polar caps being made of dry ice is in error.

New Theory Accounts for Existence of Binaries in Kuiper Belt

Robert Tindol
In the last few years, researchers have discovered more than 500 objects in the Kuiper belt, a gigantic outer ring in the outskirts of the solar system, beyond the orbit of Neptune. Of these, seven so far have turned out to be binaries--two objects that orbit each other. The surprise is that these binaries all seem to be pairs of widely separated objects of similar size. This is surprising because more familiar pairings, such as the Earth/moon system, tend to be unequal in size and/or rather close together.

Earthbound experiment confirms theory accounting for sun's scarcity of neutrinos

Jill Perry
In the subatomic particle family, the neutrino is a bit like a wayward red-haired stepson. Neutrinos were long ago detected-and even longer ago predicted to exist-but everything physicists know about nuclear processes says there should be a certain number of neutrinos streaming from the sun, yet there are nowhere near enough.

Caltech Professor to Explore Abrupt Climate Changes

Deborah Williams-Hedges
By analyzing stalagmites from caves in Sarawak, which is the Malaysian section of Borneo and the location of one of the world's oldest rain forests, and by studying deep-sea corals from the North Atlantic Ocean, California Institute of Technology researcher Jess Adkins will explore the vital link between the deep ocean, the atmosphere, and abrupt changes in global climates.
