YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.

Worm Infects Millions of Computers Worldwide
By JOHN MARKOFF
A new digital plague has hit the Internet, infecting millions of personal and usiness computers in what seems to be the first step of a multistage attack. The world's eading computer security experts do not yet know who programmed the infection, or what the next stage will be.
In recent weeks a worm, a malicious software program, has swept through corporate, educational and public computer networks around the world. Known as Conficker or Downandup, it is spread by a recently discovered Microsoft Windows vulnerability, by guessing network passwords and by hand-carried consumer gadgets like USB keys.
Experts say it is the
infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world.Worms like Conficker not only ricochet around the Internet at lightning speed, they harness infected computers into unified systems called botnets, which can then accept programming instructions from their clandestine masters.
Many computer users may not notice that their machines have been infected, and computer security researchers said they were waiting for the instructions to materialize, to determine what impact the botnet will have on PC users. It might operate in the background, using the infected computer to send spam or infect other computers, or it might steal the PC user's personal information.
Microsoft rushed an emergency patch to defend the Windows operating systems against this vulnerability in October, yet the worm has continued to spread even as the level of warnings has grown in recent weeks.
Earlier this week, security researchers at Qualys, a Silicon Valley security firm, estimated that about 30 percent of Windows-based computers attached to the Internet remain vulnerable to infection because they have not been updated with the patch, despite the fact that it was made available in October.
Unraveling the program has been particularly challenging because it comes with encryption mechanisms that hide its internal workings from those seeking to disable it.
The program uses an elaborate shell-game-style technique to permit someone to command it remotely. Each day it generates a new list of 250 domain names. Instructions from any one of these domain names would be obeyed. To control the botnet, an attacker would need only to register a single domain to send instructions to the botnet globally, greatly complicating the task of law enforcement and security companies trying to intervene and block the activation of the botnet.
Several computer security firms said that although Conficker appeared to have been written from scratch, it had parallels to the work of a suspected Eastern European criminal gang that has profited by sending programs known as "scareware" to personal computers that seem to warn users of an infection and ask for credit card numbers to pay for bogus antivirus software that actually further infects their computer.
One intriguing clue left by the malware authors is that the first version of the program checked to see if the computer had a Ukrainian keyboard layout. If it found it had such a keyboard, it would not infect the machine, according to Phillip Porras, a security investigator at SRI International who has disassembled the program to determine how it functioned.

City hall braces for busy marriage day
If love is all you need, you’ll want for nothing in New York Thursday.
The folks who hand out marriage licenses are bracing for what could be their busiest day ever as Valentine’s Day romantics head to the aisle.
“When we are really busy, we have a second chapel we can open,” said First Deputy City Clerk Michael McSweeney. “We are preparing to do that. We’re expecting a lot of couples.”
City Hall’s unofficial record of 318 weddings on that date was set on Valentine’s Day 2002 - also on a Thursday.
And love is definitely in the air Thursday.
Melanie and Joseph Castine married on Valentine’s Day 10 years ago. Today, they’re renewing their vows in the same venue - the Empire State Building.
The couple, who recently moved from Roosevelt Island to Philadelphia, won a letter-writing competition with Brides.com to become one of 14 pairs tying the knot in the iconic building.
“Valentine’s Day is just the perfect day to do it,” said Melanie Castine, who, with her hubby, has been at the skyscraper every year to mark their anniversary.
“Everywhere you go in Manhattan, you can see the Empire State Building. It’s a constant reminder of our marriage. We call it our chapel in the sky.”
Meanwhile, love is being put on ice at one of the city’s most romantic spots.
Rockefeller Center is preparing to clear its rink at 8 p.m for a skater planning to get down on one knee for a surprise engagement.
“It’s a big surprise for her, but we’re sure it’s going to be extremely romantic,” a rink spokeswoman said.
