Hans Wolfgang Liepmann, a pioneering researcher and passionate educator in fluid mechanics, passed away at the age of 94. Widely honored for his contributions to aeronautics, Liepmann came to Caltech in 1939 and was the third director of Caltech's Graduate Aeronautical Laboratories (GALCIT), from 1972 to1985.

The cells in our body are constantly receiving mixed messages. An epithelial cell might be exposed to one signal telling it to divide and, simultaneously, another telling it to stop dividing. The tug-of-war between these two sets of influences, and the effects they have on tissue growth, are explained and explored in a paper authored by scientists from Caltech and published online in the Proceedings of the National Academy of Sciences.

By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, scientists at the California Institute of Technology (Caltech) have created a material that does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition.

An innovative sky survey has begun returning images that will be used to detect unprecedented numbers of powerful cosmic explosions–called supernovae–in distant galaxies, and variable brightness stars in our own Milky Way.

The twirling seeds of maple trees spin like miniature helicopters as they fall to the ground. Because the seeds descend slowly as they swirl, they're carried aloft by the wind and dispersed over great distances. Just how the seeds manage to fall so slowly, however, has mystified scientists. In research published in the June 12 Science, researchers from Wageningen University in the Netherlands and Caltech describe the aerodynamic secret of the enchanting swirling seeds.

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into uninhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear.

Or maybe quite so soon, say researchers from Caltech, who have come up with a mechanism that doubles the future lifespan of the biosphere.

Championing the modern-day use of solar eclipses to solve a set of modern problems is the goal of a review article written by Jay Pasachoff, visiting associate at the California Institute of Technology (Caltech) and Field Memorial Professor of Astronomy at Williams College. The review is the cover story of the June 11 issue of Nature, as part of its coverage of the International Year of Astronomy.
