Getting
Supernovae
In Shape for Cosmology
Scientists
at Berkeley Lab, working with colleagues at the European Southern
Observatory (ESO) and the University of Texas at Austin, have established
that the extraordinarily bright and remarkably similar astronomical
"standard candles" known as Type Ia supernovae do not explode
in a perfectly spherical manner. Led by Lifan Wang, an astronomer
and astrophysicist in Berkeley Lab’s Physics Division, the researchers
used the ESO’s Very Large Telescope (VLT) in Chile to show that
at peak brightness the supernova 2001el exploding star was slightly
flattened, but a week later, the visible explosion was virtually spherical.
Not only can this information be used to test modesls of how Type
Ia supernovae originate and explode, Wang says, it also helps to underline
"how valid supernovae are for doing cosmology." Full
story. |

Lab
Revises Building
49 Plan; Lot Eliminated
Berkeley
Lab has issued a revised Notice of Preparation (NOP) for the
Environmental Impact Report on its proposed research office
building (Building 49). After hearing comments from the community
and considering alternatives to an earlier plan to construct
a parking lot near the site, officials have eliminated the
lot and instead plan to remove excess soils off-site. The
review period for the NOP has been extended to Sept. 5. Copies
of the revised NOP are available in the main library in Building
50. |

Committees
Examine
DOE Lab Management
The
House Science Committee's Subcommittee on Energy and the Senate
Committee on Energy and Natural Resources both held hearings
last month on the management structure of the Department of
Energy's national laboratories. Witnesses at both hearings agreed
that the nature of the relationship between the management of
the laboratories and the Department of Energy should be changed.
All agreed that present practices, both in the labs and in Washington,
can be improved. Decisions about when the government should
open up the management contracts to competition is now a forefront
issue. Read the American Institute of Physics analysis here. |

| Reporter
Takes Look At
Free-access Publishing
Rick
Weiss, science writer for the Washington Post, took
a close look at the current controversy surrounding a proposed
system that would put scientific findings on the Web -- for
free (Berkeley Lab life scientist Michael Eisen is
one of the three founders of the Public Library of Science).
This effort would overthrow the current system by which scientific
results are made known to the world -- a $9 billion publishing
juggernaut with subscription charges that range into thousands
of dollars per year. Read Weiss’ feature here. |

| Prizes,
Snacks, Pride
Available for Donors
For
those who think there’s no such thing as a free lunch,
why not be a blood donor and find out? In addition to the
juice-and-Danish snacks, the t-shirts, and the personal pride
that donors receive when giving blood to help others, they
qualify for a drawing that will award free lunches to six
lucky participants. Free dance lessons will also be among
the prizes. Walk-ins are welcome today and tomorrow, but times
are limited, so interested donors should call 6266 before
showing up. The Lab’s Summer Blood Drive is at Building
70A-3377. Hours are 8 a.m. to 2 p.m. today, and 7:30 a.m.
to 1:30 p.m. tomorrow. |
