"The amount of asymmetry measured in the B system is not enough -- by many orders
of magnitude -- to explain the cosmological problem in the universe....
[Stewart Smith, a spokesman for BaBa, said] `Clearly, we were hoping to find some

Prion and on.
"Several antibodies cleared prion clumps out of cultured mouse brain cells.

"... the two planets around the star 47 Ursae Majoris both travel in nearly
circular orbits at a distance that, in our solar system, would place them beyond
Mars but within the orbit of Jupiter."

"Intense explosions heralding the birth and death of stars most likely generated
winds that blew the boiling bubble of energy and matter "skyward" for thousands
of light years from the heart of the galaxy, said Hubble astronomers."

The Death of
TCP/IP. Why the Age of Internet Innocence is Over.
"... XP is the first home version of Windows to allow complete access to
TCP/IP sockets, which can be exploited by viruses to do all sorts of damage.
Windows XP uses essentially the same TCP/IP software as Windows 2000, except
that XP lacks 2000's higher-level security features. In order to be backward
compatible with applications written for Windows 95, 98, and ME, Windows XP
allows any application full access to raw sockets."

I just stumbled across this guy's web site. He's a mathematical physicist at UC
Riverside. Some "deep thoughts" -
John Baez:
This Week's Finds in
Mathematical Physics. (It's actually from 1996.)
"... the human brain appears to be lateralized in a fairly consistent manner;
for example, most people have the speech functions concentrated in the left
hemisphere of their cerebrum - even most, though not all, left-handers.
One might find this unsurprising: it just means that the asymmetry is encoded
in the genes. But think about it: how are the genes supposed to tell the embryo
to develop in an asymmetric way? How do they explain the difference between
right and left?"

Light's Debut: Good
Morning, Starshine!.
"The era before light, dubbed the cosmic Dark Ages, began some 300,000 years
after the Big Bang. That's when the universe had dissipated enough of the Big
Bang's heat that electrons and protons could bind together to form hydrogen
atoms. With electrons no longer free to scatter the radiation left over from
the Big Bang, that light finally streamed freely into space. As this relic
radiation faded, the cosmos plunged into darkness."

Kenneth, my nearly two-year-old, has given his older brother Christopher the
nickname "Tay."
This weekend, I was sitting on the couch with Kenneth when he got playful and
covered himself with a blanket. But before he could engage me in a game of
"peak-a-boo," he rolled off the couch and hit his head. As he cried, I uncovered
him and gave him a kiss on his head, but it wasn't enough; he wanted comfort
from his mother. Cindy came into the den and gave him a hug. This still
wasn't enough, so he left the two of us to walk across the den crying, "Tay!
Tay!"
My five-year-old was watching TV, oblivious to this domestic tragedy. Cindy
got his attention: "Christopher! Kenneth hurt himself, and he wants you to
give him a hug."
Christopher stood up, looking confused. Kenneth threw his arms around his
big brother's waist and buried his face in his chest. With a bewildered smile,
Christopher awkwardly patted Kenneth on the back.
Cindy turned to me, weepy eyed, and said, "I'm going to cry. I wish we were
taping this with the video camera."
I thought it was kind of weird. But in a sweet way.

Texas
Considers Freight Tunnel As Truck Traffic Continues Rise.
"Is a 400-mile underground freight pipeline the best way to relieve truck
congestion in Texas? ... So far, the Texas Transportation Institute, part of the
Texas A&M University system, has concluded it's technically feasible to build a
below-ground route for unmanned rail vehicles. And the institute's ongoing
five-year study has found the cost of moving a truckload along a
Dallas-to-Laredo underground route would be $40, one-third as much as a
tractor-trailer along the same route above ground."

Fishing for Neutrinos.
"At depths greater than about three quarters of a mile, the pressure inside the
glaciers squeezes out air bubbles, creating an extremely transparent medium in
which a photon of light travels an average of 700 feet before being absorbed.
Down there, the ice is bathed in a continuous blue glow from millions of
sparking muons."
