HOW TO BUILD A TIME MACHINE  by Paul Davies
Is time travel possible? Yes, says Davies, who recently retired (in
his early 50s) as professor of mathematical physics at the University
of Adelaide in Australia to concentrate on his writing. But "a
moment's thought uncovers some tricky questions." Whereupon he 
discusses lucidly and engagingly both the concepts of physics that 
establish the possibility of time travel and the tricky questions. 
You could reach the future "by simply moving very fast." For visiting 
the past, the most popular proposal is a wormhole, "a sculpture 
in the structure of space that provides a shortcut between two widely 
separated spaces." There may be "cosmic taboos," though, that make 
time travel forever elusive.

** CLIMATE WARMING CAUSES COLLAPSE OF ANTARCTIC ICE SHELF 
The northern section of the Larsen B ice shelf--a slab of floating 
ice on the eastern side of the Antarctic Peninsula--has collapsed and 
separated from the continent, researchers report. The incident is the 
largest single event in a 30-year series of ice shelf retreats in the
area and appears to be the result of rapid warming there.

** A WAY WITH WORDS
The way you speak says a lot about you. Your dialect or accent might 
indicate where you grew up, for instance, while your vocabulary may 
suggest the type of education you've had. But can the language you 
use indicate the way you think, or help shape those thoughts? In the 
1930s, American linguist Benjamin Lee Whorf argued persuasively that 
language did indeed affect thought, but his views fell out of favor. 
Now a group of cognitive psychologists has revived the search for 
the effects of language on the mind, with some provocative results.

** CHANDRA ILLUMINATES DIFFERENCE BETWEEN DISTANT DOUBLE QUASARS 
Since its discovery more than two decades ago, the double quasar 
system Q2345+007A,B has confounded astronomers. Often such apparent
quasar pairs are in fact optical illusions caused by so-called
gravitational bending. New results from the Chandra X-ray Observatory,
however, suggest that the twins are in fact distinct objects formed 
by merging galaxies.

** ETHIOPIAN FOSSIL DISCOVERY PRUNES HUMAN FAMILY TREE  
Scholars of human evolution have long debated just how many branches 
and twigs make up the human family tree. Some place the known human 
fossils into numerous genera and species, creating a bushy tree. 
Others tend to see more similarities between fossils and opt for trees
with fewer offshoots. Now recently recovered fossils from Ethiopia
indicate that for at least one part of the human pedigree, less
is more.

ASK THE EXPERTS
====================================================
HOW LONG CAN HUMANS STAY AWAKE?

J. Christian Gillin, a professor of psychiatry at the University of 
California, San Diego, explains.
