How environmental friendly is hydrogen? Researchers
wonder and argue how environmental friendly hydrogen will become, when
in - let's say - 20 or 50 years half or whole global economy is
transformed to a so-called hydrogen economy, reports Manfred Lindinger
in FAZ (October 24, 2003). According
to a recent article from U.S. researchers in Science magazine hydrogen
released by leakage will become harmfull to the ozone layer in the stratosphere.
In response, the German society of chemists (GDCh) puts the demand for
more detailed analysis of the issue on the agenda. Especially the assumptions
of the U.S. study have been heavily criticized. But this week a research
report (also published in Science) from the German Max-Planck-Institute
of Meteorology, Hamburg, states that it is merely improbable that released
hydrogen has any impact on environment. They assume a maximum leakage
of about three percent, whereas the U.S. study puts 10 to 20 percent. |

Freshly stirred blood from powder German researchers
are sceptic about the recent success in artificial blood treatment as
reported by doctors of the Swedish Karolinska Hospital. Michael Brendler
writes in Süddeutsche Zeitung (October
24, 2003)
the Swedish researchers claim to have replendished blood loss during operation
by artificial blood at first time. The blood was stirred from a powder
just before operation. "That's a step forward, but no breakthrough",
says the German anaesthesist Oliver Habler. One reason is simply the small
sample of eight patients having received the treatment. |

Problems on Space Station Stir Debate The International Space Station has some troubles including damaged air, water and radiation monitors and ailing medical devices, Andrew C. Revkin and Warren E. Leary report in The New York Times (October 24, 2003). However, astronauts aboard the station said in news conferences Thursday they believe the station to be safe for now. They and several space agency officials reported that they are carefully watching the problem. An evacuation plan for the astronauts is in place should they be forced to leave the station quickly. Women With Genetic Mutation at High Risk for Breast Cancer, Study Confirms A new study
found that women who carry a genetic mutation linked to breast cancer
are getting the disease at an earlier age than previous generations. But
the findings, Denise Grady reports in The New York Times (October
24, 2003), "apply to only a small proportion of breast cancer
patients." Women affected by these findings have mutations in the
genes BRCA1 or BRCA2. They account for between 5 and 10 percent of all
new cases every year. The new study also suggests that women with these
mutations are at higher risk to develop breast cancer regardless of family
history. A healthy lifestyle can push out the start of cancer. The study
indicates that women who were not overweight and exercised as teenagers
were less likely to develop cancer early on. |

In the German
weekly Die Zeit (October
23, 2003) Max Rauner gives a portrait of Yakir Aharonov. The physicist
from Israel thinks about a new interpretation of quantum theory: a so-called
"weak measurement" could help physicists to understand the abstract framework
of the theory. Absurdly: in the new theory of Aharonov time is allowed
to go backwards. |

Advisers
to the World Health Organization recommend countries use SARS tests sparingly
"to avoid unnecessary scares and overburdening hospitals during flu
season," Antonio Regalado and Betsy McKay report in The Wall Street
Journal (October 23, 2003).
The reason for their recommendation is that the tests for the respiratory
disease are still unreliable. The group of advisers also recommends that
countries with lower risks of SARS such as the United States use these
tests only as a last resort while regions such as the southern China area
where SARS could re-emerge easily "should immediately test all cases
of unexplained pneumonia for possible SARS." In a related story on
Oct. 20, Betsy McKay reported that
the federal Centers for Disease Control and Prevention propose an aggressive
program to quarantine SARS cases to keep the disease from spreading. "In
the absence of any known treatment or vaccine, the CDC's proposed actions
which include closing businesses, schools and transit systems, as well
as restricting travel are among the only tools currently available to
public health officials for controlling the spread of SARS, which sickened
8,098 people globally earlier this year and killed 774." |

Low-Cost Supercomputer Made with 1,100 PC's The fastest
computer in the world may be a low-cost supercomputer faculty, technicians
and students at Virginia Polytechnic Institute have put together "from
off-the-shelf personal computers in just one month at a cost of slightly
more than $5 million," John Markoff writes in The New York Times
(October
22, 2003). The fastest machines traditionally have cost anywhere between
$100 million and $250 million and were constructed over several years.
"The Virginia Tech supercomputer, put together form 1,100 Apple Macintosh
computers, has been successfully tested in recent days, according to Jack
Dongarra, a University of Tennessee computer scientist who maintains a
listing of the world's 500 fastest machines," Markoff reports. Official
results are expected to be published next month. |

Watching
the Nobel Prize announcements became a sport every October for scientists
and journalists. There are the winners and - maybe losers: those who feel
ignored, get angry and bring it to the public. This year Raymond Damadian
claimed in full-page advertisments in the Washington Post and the New
York Times of getting passed over by the Nobel committee. Horace Freeland
Judson picked up the issue in an editorial in the New York Times (October
20, 2003). He reports about lots of researchers with major contributions
to a scientific discovery or achievement that have been passed over -
Lise Meitner, Rosalind Frankling, for instance. In many cases the predecessors
of a discovery are included, others are left out. "The noisy complaining
of Raymond Damadian" may show that the committees decisions aren't
perfect, but also that you can't do anything right to the people. |

Women sick
of keeping up with taking a daily dosis of the pill as an option for birth
control can breathe out and relax. The pill for men seems to work according
to an Australian study, Amanda Ripley reports in the Time Magazine (October
20, 2003). But don't show your Schadenfreude too soon. It may still
take up to five years before the pill for men reaches the market. |

Controversy about Damadian's Nobel claim The readers
of Dagens Nyheter (October
20, 2003) were confronted with Raymond Damadian's one-page accusations
against the Nobel committee. Damadian claims that he deserves a share
in this year's Nobel Prize for medicine for having used magnetic resonance
in tumour research some time before Peter Lauterbur and Peter Mansfield.
Per Snaprud summarizes
(on October 21, 2003) the views on Damadian's actions. Anders Hemmingson,
Professor emeritus of radiology at Uppsala University, believes that Damadian
is right and that he should have a share in the prize. Peter Stilbs, physical
chemist from the Royal Institute of Technology in Stockholm disagrees.
He claims that only medical scientists were impressed with Damadians work,
whereas physicists and chemists were critical from the start. Trouble
for Damadian may, however, come from unexpected directions: in his advertisement
he used a picture of the Nobel Medal, which unfortunately is copyright
protected. Rumors have it that the Nobel Foundation is considering suing
Damadian for breach of copyright. |

Ingrid Perssons
reports in Svenska Dagbladet (October
19, 2003) from the Institute of Toy Research at Strockholm's Royal
Institute of Technology. Although the worldwide market for toys amounts
to approximately 60 billion euros, the field is hardly ever scrutinized
scientifically. The new institute provides a home for both pedagogical
and technical research. The researchers can boast one soon marketable
product: a computer game for visually impaired children, which is based
on sound effects. |

Open question about the shape of the universe Is the universe
infinite or just very, very large? On the occasion of a recent Nature
paper by Jeffrey Weeks and his co-workers, Maria Gunther Axelsson portrays
in Dagens Nyheter (October
19, 2003) current ideas on the shape and topology of the universe.
He presents criticisms of Jeffrey Weeks claims that the universe is shaped
like a dodecahedra and gives a prominent place for the views of Max Tegmark,
who isn't really sure about the universe's shape but bets that by 2010
a certain answer will be forthcoming. The article is
accompanied by a revealing survey among Swedish 10-year old children
concerning their thoughts on universe. The topology of the universe is
of less concern to the children (the universe is generally considered
to be very, very large) than the existence and possible look of aliens. |
