"I love Microsoft and Microsoft did not
lose me," protested Robert Scoble, a little too loudly, on his blog last week,
in a bid to end feverish speculation in the blogosphere about why, exactly, he
had decided to leave Microsoft. The software giant's "technical evangelist", Mr.
Scoble has become the best-known example of a corporate blogger. On his blog,
called Scobleizer, which he started in 2000, he writes about Microsoft's
products, and has sometimes criticised them fiercely—thereby both establishing
his credibility and, by its willingness to tolerate him, helping to humanise his
employer. As blogging's influence has grown, so bas Mr.
Scoble's—both inside and outside Microsoft. Last year, after he blogged against
Microsoft's decision to abandon support for a law prohibiting discrimination
against gays, the company's managers backed down. He helped write a book, Naked
Conversations: How Blogs Are Changing the Way Businesses Talk With Customers,
published in January, that has become essential reading for any boss trying to
define a new-media strategy for his business. So why leave? Mr.
Scoble has denied several of the theories circulating in the blogosphere,
including that he had become fed up with having his expenses challenged or with
sharing an office; that Microsoft challenged his views too often; that he had
become, frustrated; and that the firm had not tried hard enough to keep him.
Still, his friend Dave Winer, another blogger, described Microsoft as a
"stifling organisation" before observing that "when he finally decided to leave,
it's as if a huge weight came off him, and all of a sudden, the old Scoble is
back." He views Mr. Scoble's departure as evidence that Microsoft has been
unable to move with the times: "I'm glad to see my old friend didn't go down
with the ship." Another blogger says that his departure shows the "end of honest
blogging." The real reason may be less sinister—though troubling
for the growing number of employers encouraging their employees to biog.
Blogging allows staff to build a personal brand separate from that of their
firm; if they are good at it, and build up a readership, that brand may be more
valuable to them elsewhere. Mr. Scoble is off to join PodTech. net, a rising
star in video podcasting, which is now far more fashionable than blogging and
potentially far more lucrative. It seems that Mr. Scoble is most impressed by
Rocketboom, one of whose founders, Amanda Congdon, is said to be drawing 300000
viewers a day to her videoblog, and is about to start charging advertisers
$85000 a week—almost as much, Mr. Scoble is reported as saying, "as I made in an
entire year working at Microsoft."

When is an endangered species not an endangered
species? When it lives in the sea, apparently. Despite continuing carnage in the
ocean, marine creatures were refused any protection at the United Nations
conference on trade in wildlife that ended yesterday in Doha, Qatar.
Tigers, rhinos and elephants are all better protected after the meeting
of the Convention on International Trade in Endangered Species (Cites). But
hammerhead sharks, bluefin tuna and other marine species should be quaking in
their skins. For when it comes to fish, the world has decided that scientific
evidence of imminent demise is not reason enough to defend them against
overexploitation. The conflict between trade and conservation is nothing new,
but it is pretty well established that if you let trade in wildlife run rampant
(蔓延的), soon there will be nothing left to sell. That is why the UN set up Cites
in the first place. So why did fish get such a raw deal? Is it
that we care less about life that is so very different from us? Do the
emotionless eyes of fish leave our hearts cold? Is it an extension of the
convenient myth that fish feel no pain? The truth is far more shocking. All
fingers of blame point directly at Japan. The high value of bluefin tuna--a
single specimen can reach $112 000--led it to orchestrate a full-scale campaign
against proposals to ban trade in the species. Diplomatic missions were sent to
developing nations to bully them into agreeing with Japan's conviction that fish
cannot be endangered. That way of thinking is grounded in
ignorance. The oceans long seemed infinite in their capacity to produce such
riches, and any sign that this was not so was hidden by our inability to peer
into the depths. Science has now stripped back the veil and revealed the extent
of the depletion. It is this science that Japan and its allies have chosen to
not to see. Unfortunately for life in the sea, Japan's
campaign made waves far beyond the bluefin. Sharks are in dire trouble thanks to
some people's appetite for using their fins in soup. About 73 million sharks are
killed each year as a result, and sharks don't reproduce fast. But far from
favoring a ban, nations voted against even the most basic monitoring of the
trade. Red and pink corals have now all but vanished
from the Mediterranean and are being stripped from the Pacific, but proposals to
control that trade were also swept away. Fish don't recognise borders and
boundaries. Yet one nation, Japan, by its cynical use of political power is
robbing the world of a shared resource.

Mark Twain once observed that giving up
smoking is easy. He knew, because he' d done it hundreds of times himself.
Giving up for ever is a trifle more difficult, apparently, and it is well known
that it is much more difficult for some people than for others. Why is this
so? Few doctors believe any longer that it is simply a question
of will power. And for those people that continue to view addicts as merely
"weak", recent genetic research may force a rethink. A study conducted by
Jacqueline Vink, of the Free University of Amsterdam, used a database called the
Netherlands Twin Register to analyze the smoking habits of twins. Her results,
published in the Pharmacogenomics Journal, suggest that an individual' s degree
of nicotine dependence, and even the number of cigarettes he smokes per day, are
strongly genetically influenced. The Netherlands Twin
Register is a voluntary database that contains details of some 7,000 pairs of
adult twins (aged between 15 and 70) and 28,000 pairs of childhood twins. Such
databases are prized by geneticists because they allow the comparison of
identical twins (who share all their genes) with fraternal twins (who share
half). In this case, however, Dr. Vink did not make use of that fact. For her,
the database was merely a convenient repository of information. Instead of
comparing identical and fraternal twins, she concentrated on the adult fraternal
twins, most of whom had completed questionnaires about their habits, including
smoking, and 536 of whom had given DNA samples to the register.
The human genome is huge. It consists of billions of DNA "letters", some
of which can be strung together to make sense ( the genes) but many of which
have either no function, or an unknown function, To follow what is going on,
geneticists rely on markers they have identified within the genome. These are
places where the genetic letters may vary between individuals. If a particular
variant is routinely associated with a particular physical feature or a behavior
pattern, it suggests that a particular version of a nearby gene is influencing
that feature or behavior. Dr. Vink found four markers which
seemed to be associated with smoking. They were on chromosomes 3, 6, 10 and 14,
suggesting that at least four genes are involved. Dr. Vink hopes that finding
genes responsible for nicotine dependence will make it possible to identify the
causes of such dependence. That will help to classify smokers better (some are
social smokers while others are physically addicted) and thus enable "quitting"
programs to be customized. Results such as Dr. Vink' s must be
interpreted with care. Association studies, as such projects are known, have a
disturbing habit of disappearing, as it were, in a puff of smoke when someone
tries to replicate them. But if Dr. Vink really has exposed a genetic link with
addiction, then Mark Twain' s problem may eventually become a thing of the
past.

单选题Lonely people, it seems, are at greater risk than the gregarious of developing illnesses associated with chronic inflammation, such as heart disease and certain cancers. A paper published last year in the
Public Library of Science, Medicine
, shows the effect on mortality of loneliness is comparable with that of smoking and drinking after examining the results of 148 previous studies and controlled for factors such as age and pre-existing illness.
Steven Cole of the University of California, Los Angeles, thinks he may know why this is so. He told the American Association for the Advancement of Science meeting in Washington, D.C., about his work studying the expression of genes in lonely people. Dr. Cole harvested samples of white blood cells from both lonely and gregarious people. He then analysed the activity of their genes, as measured by the production of a substance called messenger RNA. This molecule carries instructions from the genes telling a cell which proteins to make. The level of messenger RNA from most genes was the same in both types of people. There were several dozen genes, however, that were less active in the lonely, and several dozen others that were more active. Moreover, both the less active and the more active gene types came from a small number of functional groups.
Broadly speaking, the genes less active in the lonely were those involved in staving off viral infections. Those that were more active were involved in protecting against bacteria. Dr. Cole suspects this could help explain not only why the lonely are iller, but how, in evolutionary terms, this odd state of affairs has come about.
The crucial bit of the puzzle is that viruses have to be caught from another infected individual and they are usually species-specific. Bacteria, in contrast, often just lurk in the environment, and may thrive on many hosts. The gregarious are therefore at greater risk than the lonely of catching viruses, and Dr. Cole thus suggests that past evolution has created a mechanism which causes white cells to respond appropriately. Conversely, the lonely are better off ramping up their protection against bacterial infection, which is a bigger relative risk to them.
What Dr. Cole seems to have revealed, then, is a mechanism by which social environment reaches inside a person"s body and tweaks its genome so that it responds appropriately. It is not that the lonely and the gregarious are genetically different from each other. Rather, their genes are regulated differently, according to how sociable an individual is. Dr. Cole thinks this regulation is part of a wider mechanism that tunes individuals to the circumstances they find themselves in.
