demandent à Poutine d'arrêter la fuite
des cerveaux Известные ученые России обратились к президенту

Des scientifiques russes de renom ont appelé
lundi le président Vladimir Poutine à prendre des mesures
contre la fuite des cerveaux, qui menace selon eux l'avenir de la science
en Russie, lors d'une réunion du Conseil sur la science et les
hautes technologies.
Entre 1990 et 1998, le secteur de la science en
Russie "a perdu plus d'un million d'employés, soit plus
de 54% de ses cadres", certains chercheurs ayant quitté
le pays, d'autres ayant changé d'emploi, a expliqué
le recteur de l'université Lomonossov de Moscou, Viktor
Sadovnitchi, au cours de la réunion à laquelle
assistait M. Poutine. Le Conseil sur la science et les hautes
technologies réunit une vingtaine de chercheurs réputés,
membres de l'Académie russe des sciences, dont le prix
Nobel de physique Jaurés Alferov.
La "deuxième vague de l'émigration
scientifique", qui a débuté à la fin des
années 90, est marquée par "le départ des
plus jeunes chercheurs, spécialistes dans les domaines les plus
modernes et les hautes technologies, dont les mathématiques, la
physique et la biovirologie, la génétique et la biochimie",
a regretté M. Sadovnitchi.
"Près de trente mille chercheurs travaillent à
l'étranger sur contrat et une partie d'entre eux n'ont pas l'intention
de revenir en Russie, où les salaires ne sont pas comparables avec ceux que
peuvent proposer les employeurs étrangers", a souligné le
recteur.
"S'en vont ceux qui ont le plus de talent
et qui travaillent avec le plus de productivité", a-t-il
relevé, ajoutant que la recherche scientifique en Russie avait "des
problèmes qui ne peuvent pas
être réglés sans la participation du président".
"Le financement de la science a été multiplié par 2,5
depuis l'an 2000 et celui de l'éducation par plus de trois. Ce n'est
peut-être pas suffisant, mais c'est ce que l'Etat peut faire en tenant
compte des possibilités du budget" national, a souligné de
son côté Vladimir Poutine.

“Do you understand what you've done?!
Now, we have two options. Either we kill you or chuck the whole
oil-refining industry!” This is how the industry's major players reacted
when they heard about the new technology developed two years ago by
scientists at Novosibirsk's G.K. Boreskov Catalysis Institute, part of the
Siberian Branch of the Russian Academy of Sciences. In contrast to the
traditional multi-stage process, the Novosibirsk technique refines oil in
only one stage. The process yields high-octane gasoline and high-quality
diesel oil that meet even the tightened environmental regulations recently
introduced in Europe. Most importantly, however, the production of
excellent quality fuel using the new technology costs several times less
than older methods. The Catalysis Institute is no typical Russian academic
establishment. Throughout its history, its scientists have only rarely
pursued pure scientific curiosity. As a rule, they have been guided in
their research by the needs of various industries. Virtually all
developments at the Institute have found their buyers. The new,
single-stage technology is no exception. At the Expert's second Russian
Innovation Competition, the know-how from Novosibirsk took the British
Council prize. It is already in use at several companies. The light
fractions The discovery from Siberia only involves the so-called “top,”
the light fractions of crude oil that are refined into gas and diesel, and
not fuel oil. Using traditional refining technology, after initial
distillation, the gasoline, kerosene, and diesel fractions are each
further refined via separate processes. Thus, one method for refining the
gasoline fraction into high-octane gas involves hydrotreatment (which
removes sulfur and nitrogen), reforming, and alkylation. The diesel
fraction is generally refined into what is referred to as “winter-grade
diesel” in Russia and undergoes hydrotreatment and dewaxing. For more than
a hundred years of this technology, each fraction has been processed
separately using separate catalysts. Platinum catalysts are used in
reforming, cobalt-molybdenum catalysts in hydrotreatment, and platinum and
palladium catalysts in dewaxing. There have been many attempts to shorten
this long chain and optimize the process, but all innovators were hampered
by a single pre-existing assumption. They believed it was impossible to
refine several different fractions at the same time (meaning in one
reactor with one catalyst). The Novosibirsk scientists, however, proved
them wrong. The super catalyst The new, single-stage method, when
everything is processed at the same time, is called Binary Motor Fuel or
BMF technology. It is very simple: after primary oil distillation, all
light fractions are fed into one reactor block where the refining process
takes place. Then, the resulting compound is directed into a dividing
block where it is split into three final products, high-octane gasoline,
winter diesel, and propane-butane. The last fraction yields a liquefied
gas that can be used as both a household and automotive fuel. The beauty
of the new method lies in a unique catalyst that is loaded into a reactor.
The idea of a catalyst that could process heavy and light fractions at the
same time without the processes interfering with each other occurred to
Gennady Yechevsky, Doctor of Chemistry and the Head of the Catalytic
Hydrocarbon Transformation Laboratory. He assumed that if a catalyst's
structure were transformed in a special way, its active centers (the
special areas of a catalyst where specific chemical reactions can take
place) would occur with non-uniform density. In this case, diverse
reactions, such as aromatization, alkylation, cracking, desulfurization,
and isomerization, could take place at the same time on these active
centers. The speed ratio of these reactions would allow all fractions to
be processed in same amount of time, without clogging the active centers.
The entire lab group, a scientifically strong team with several promising
developments for the oil-refining and petrochemical industry to its
credit, got to work on the new technology. Together they invented an
industrial synthesis technique for this elegant catalyst. The method for
redistributing active centers in the volume of a catalyst constitutes a
fundamental innovation, as the material scientist chose to use in the new
process – high-silica zeolite – is nothing new. The lab ran pilot trials
of the new method in 2001, just one year after the discovery of the super
catalyst idea. The first experimental industrial trials were already
underway in August 2003. They proved Yechevsky's theory. Clean, cheap,
and beautiful Thanks to BMF technology, the oil refining process has
becomes considerably simpler. It no longer involves complex and costly
processes, such as hydrotreatment (and cumbersome and troublesome hydrogen
facilities), reforming, isomerization, alkylation, dewaxing, and various
rectification stages. Capital expenditures are six times less and
operating costs are at least eight times less, compared to the traditional
process. BMF technology also uses at least four times less energy. The BMF
catalyst– in contrast to the expensive and touchy noble metals used in the
traditional process – is convenient in all respects: it is cheap,
non-aggressive, and undemanding to boot. There is one more essential
advantage to the Novosibirsk technology: it can refine oil with absolutely
any concentration of sulfur compounds. When refining “dirty” oil using
traditional method, hydrotreatment costs increase dramatically. Sulfur has
to be removed, as it rapidly destroys the catalysts used in the next
refining stages. Therefore, oil refineries are not eager to accept oil
with high sulfur content for further refinement, because costs are too
high. Russia, however, has a large amount of high-sulfur oil. The new
zeolite catalyst isn't afraid of sulfur at all. That's why it doesn't
matter in BMF technology how much sulfur the raw crude contains. Gulping
up “sour” crude with ease, the BMF method yields fuel with a sulfur
content of less than 0.001% (whereas under Russian state standards, 0.05%
is considered good). Another advantage of BMF technology is the low benzol
content of the resulting fuel. Benzol is carcinogenic when burned and
Russian state standards set an upper limit of 5% for benzol concentration
in fuel. The maximum benzol percentage under European standards is 1%. BMF
technology produces fuel with a benzol content of less than 1%. BMF
technology also produces excellent winter diesel. Traditional diesel fuel
is considered high-quality if it remains liquid at -35єC. The Novosibirsk
fuel doesn't freeze even at -75єC. If oil is refined using the traditional
process, about 25% of the gasoline turns into a gas and is lost. BMF's
developers have outperformed the older method here, too. They have
succeeded in achieving much higher liquid yield, the most valuable
fraction. The maximum “gas losses” run less than 18%. However, even this
18% cannot really be called a loss. The propane-butane content of this gas
is as high as 95%. “A patent search has shown that there is other
technology of this kind anywhere in the world. We already have four
Russian and two international patents for a number of variations of BMF
technology. Seven more patent applications for the innovations we made
during our work are currently under consideration,” Yechevsky
says. Fueling ambitions The BMF technology presents a radical break
with existing oil refining processes. This, however, prevents BMF
technology from be applied immediately industry-wide. It is not that
simple to fit the new technology into the complex, multi-stage production
cycle at oil refineries. While waiting for a response from “big oil,”
Catalysis Institute officials have focused on promoting their technology
in more limited niches, where smaller oil refineries are being set up from
scratch. These include plants in remote and hard-to-reach areas, in
particular in the Far North. Building oil refineries using the Novosibirsk
technology also proves economically sound when developing new oil
deposits. Secondly, the new technology is ideal for processing “problem”
crude with large amounts of sulfur or paraffin. Plants bluntly refuse to
accept some grades of this kind of oil, and in such cases there is simply
no commercially viable alternative to BMF technology. There is one more
promising market. Using the new technology, it would be possible to
process gas condensate efficiently, as the liquid fraction is separated
from the gas produced in order to send only residue gas through the main
pipeline. Gas condensate is an ideal input for BMF technology. It is a
mixture of mainly light oil fractions, and its fuel oil content is very
low. The developers also hope to fuel the ambitions of regional
politicians for promoting BMF technology. Officials in regions without
their own oil refineries often want motor fuel production in their area to
avoid price gauging at crucial moments like sowing and harvesting. Using
BMF technology, they could build a compact and inexpensive oil refinery on
a regional scale

29.01.2004, 19.27 Russia Academy of
Sciences may be exempt from paying for land Российская Академия наук может быть освобождена от
платы за землю
|
MOSCOW, January 29 (Itar-Tass) -- The Duma
committee for property has supported the bill of Academician Zhores
Alferov suggesting the exemption of the Russian Academy of Sciences and
its institutions from the payment for land, Viktor Pleskachevsky, the
chairman of the committee, told the press. “The committee has endorsed
the amendments to Russia's Land Code suggested by deputy Alferov under
which the Russian Academy of Sciences and its institutions will be exempt
from the payment for land on the same basis as state institutions,”
Pleskachevsky said. According to the Land Code, plots of land are
provided for termless use to state organisations only while other
enterprises and organisations must either buy them out before January 1,
2006, or to acquire the right of lease of plots of land on which they are
situated. The presidium of the Russian Academy of Sciences told Tass
that the academy, under its charter, is a non-commercial organisation with
a state status, rather than a state institution. “We have supported
this approach as the funding of academic institutions is yet low and the
payment for plots of land used by the academy consume considerable part of
the funding,” Pleskachevsky said. He said the bill would have the
first reading at the plenary meeting of the State Duma in early March.

11.38 First Russo-American technology
symposium Первый
русско-американский симпозиум по сотрудничеству двух стран в
области высоких технологий
|
PALO-ALTA (CALIFORNIA), - The first
Russo-American technology symposium is currently under way at Stanford
University here. Its purpose is to promote the Russo-American contacts in
the field of science-intensive technologies. Co-Chairman of the
Symposium and Russian Acting Minister of Industry, Science and Technology
Andrei Fursenko told Itar-Tass that the forum's main task and end-goal
should be to improve the relationships between partners in both countries.
He expects the symposium to serve as a catalyst for the promotion of
cooperation in this domain. President of the American Chamber of
Commerce in Russia Andrew Somers shared this view. The main goal is to
achieve better understanding among American investors, he noted. At
present, U.S. investors in information technologies have, as a rule, a
very faint idea of the opportunities offered by the Russian information
technology market and of its potential, he added. Therefore, the current
symposium will help them acquire a better understanding of the situation,
Somers pointed out. In turn, President of the Boeing-Russia/CIS
Company Sergei Kravchenko, who is representing the Boeing Corporation,
described the symposium as a very useful meeting of leaders of the Russian
and American science-intensive industries, wishing to cooperate with each
other.

Add Their Atomic Mass to Periodic Table Команда российских и американских ученых под

Объединенном институте ядерных исследований в Дубне, заявила о

A team of Russian and American scientists
are reporting today that they have created two new chemical elements,
called superheavies because of their enormous atomic mass. The discoveries
fill a gap at the furthest edge of the periodic table and hint strongly at
a weird landscape of undiscovered elements beyond. The team, made up
of scientists from Lawrence Livermore National Laboratory in California
and the Joint Institute for Nuclear Research in Dubna, Russia, is
disclosing its findings in a paper being published today in Physical
Review C, a leading chemistry journal. The paper was reviewed by
scientific peers outside the research group before publication. "Two new
elements have been produced," said Dr. Walt Loveland, a nuclear chemist at
Oregon State University who is familiar with the research. "It's just
incredibly exciting. It seems to open up the possibility of synthesizing
more elements beyond this." The periodic table is the oddly shaped
checkerboard — with an H for hydrogen, the lightest element, in the
upper-left-hand corner — that hangs in chemistry classrooms the world
over. Each element has a different number of protons, particles with a
positive electrical charge, in the dense central kernel called the
nucleus. The number of protons, beginning with one for hydrogen, fixes an
element's place in the periodic table and does much to determine an
element's chemical properties: ductile and metallic at room temperature
for gold (No. 79), gaseous and largely inert for neon (10), liquid and
toxic for mercury (80). Elements as heavy as uranium, No. 92 on the
list, are found in nature, and others have been created artificially. But
much heavier elements have been difficult to make, partly because they
became increasingly unstable and short-lived. Still, for roughly half a
century, nuclear scientists have been searching for an elusive "island of
stability," somewhere among the superheavies, in which long-lived elements
with new chemical properties might exist. Dr. Loveland said that the new
results indicated that scientists might be closing in on that island.
"We're sort of in the shoals of the island of stability," said Dr.
Kenton J. Moody, a Livermore nuclear physicist who was one of the
experimenters in the work. "It's an amazing effect," he added. "We're
really just chipping away at the edges of it." The experiments took
place at a cyclotron, a circular particle accelerator, in Dubna, where the
scientists fired a rare isotope of calcium at americium, an element used
in applications as varied as nuclear weapons research and household smoke
detectors. Four times during a month of 24-hour-a-day bombardment in July
and August, scientists on the experiment said, a calcium nucleus fused
with an americium nucleus and created a new element. Each calcium
nucleus contains 20 protons and americium 95. Since the number of protons
determines where an element goes in the periodic table, simple addition
shows the new element to bear the atomic number 115, which had never been
seen before. Within a fraction of a second, the four atoms of Element 115
decayed radioactively to an element with 113 protons. That element had
never been seen, either. The atoms of 113 lasted for as long as 1.2
seconds before decaying radioactively to known elements. Scientists
generally do not give permanent names to elements and write them into
textbooks until the discoveries have been confirmed by another laboratory.
By an international convention based on the numbers, element 113 will be
given the temporary name Ununtrium (abbreviated Uut for the periodic
table) and element 115 will be designated Ununpentium (Uup). Dr.
Loveland said he agreed that the new elements would require independent
confirmation before they could receive final acceptance. And he conceded
that the Dubna find was likely to receive more than the usual amount of
scrutiny: two years ago, the reported discovery of Element 118 was
retracted after a scientist at Lawrence Berkeley National Laboratory was
found to have fabricated evidence.

2004 Melting Siberian Peat Bogs May
Unleash Huge Quantities Of Methane Таяние
сибирских торфяных болот может освободить огромное количество
метана
|
Massive Siberian peat bogs, widely known as
the permanently frozen home of untold kilometers of moss and uncountable
hordes of mosquitoes, also are huge repositories for gases that are
thought to play an important role in the Earth's climate balance,
according to newly published research by a team of U.S. and Russian
scientists in the journal Science. Those gases, carbon dioxide and
methane, are known to trap heat in the Earth's atmosphere, but the
enormous amounts of the gases contained in the bogs haven't previously
been accounted for in climate-change models. The new research, said
Laurence Smith, an associate professor at the University of California and
primary author of the paper, could help to refine those materials. Smith's
work was funded by the National Science Foundation (NSF). A key finding of
the research, unrelated to modern climate change, is that the bogs
themselves came into being suddenly about 11,500 to 9,000 years ago - much
earlier than previously thought - and expanded very rapidly to fill the
niche they now occupy. Their appearance coincides with an abrupt and well
documented spike in the amount of atmospheric methane recorded in ancient
climate records. The finding counters previously held views that the bogs
were largely unchanged - and unchanging - over millennia. The rapid
appearance of the bogs provides strong evidence that this is not the case.
Scientists have hotly debated the origin of the methane spike,
variously attributing it to sources in tropical wetlands and offshore
sediments. The new research conclusively points for the first time to
Siberia as a likely methane source. But the researchers also point out
that the bogs - which collectively cover an area of roughly 603,000 square
kilometers - have long absorbed and held vast amounts of carbon dioxide,
while releasing large amounts of methane in the atmosphere. If, as
many scientists predict, a regional Arctic warming trend thaws the bogs
and causes the trapped gases to be released into the atmosphere, that
could result in a major and unexpected shift in climate trends, according
to the researchers. The teams spent three seasons in the Siberian Arctic,
drilling several meters down into the sphagnum moss to produce the peat
samples for analysis. Smith said thawing of the permafrost would
essentially turn the carbon and methane balance in the peat bogs from a
scientific constant in climate-change equations to a variable.
"Traditionally, we had thought these areas were simply a gradually
varying source of methane and an important sink for atmospheric carbon,"
he said. "They've been viewed as a stable thing that we always count on.
The bottom line is Siberian peat lands may be a bigger player in climate
change than we knew before." "There are natural sources of greenhouse
gases out there that are potentially enormous that we need to know about,"
Smith said. "One of the concerns is that up until now, the bogs have been
more or less a sink for CO2, absorbing carbon dioxide from the atmosphere.
In an extreme scenario, not only would they stop taking up CO2, they would
release a lot of the carbon they have taken up for centuries." Smith
conceded that the team searched their Siberian peat samples for evidence
that such a drastic release of gas occurred in the past, with inconclusive
results. But, he added, as other research into Earth's ancient climate
begins to yield evidence that changes have occurred before, accounting for
unknowns such as the carbon and methane balance in the bogs becomes more
important. "It emphasizes a point that has been emerging over the past few
years; the idea that the climate system is highly unpredictable and full
of thresholds that can trigger greenhouse gas sources and sinks to
abruptly switch on and off," he said. "The more of them we can identify,
the more accurately we can model and anticipate changes in the future."

09:30 09 February 04 Russia reviving massive river diversion plan Вновь разрабатывается советский план по изменению
русла крупнейших сибирских рек с целью обеспечения водой
засушливых районов бывших советских республик Центральной Азии.
|
Russian scientists are reviving an old
Soviet plan to divert some of Siberia's mightiest rivers to the parched
former Soviet republics of central Asia. Its backers say it will solve a
growing water crisis in the region and replenish the now desiccated Aral
Sea, once the world's fourth-largest inland sea. The $40 billion scheme
could also gain international support. Recent increases in the flows of
Siberia's rivers, probably due to global warming, have raised fears that a
less salty Arctic Ocean could shut down the Gulf Stream and trigger icy
winters across Europe. Diverting part of the flow of the rivers could
prevent that But some experts say that the hugely ambitious scheme
will cause social, economic and environmental disaster. The megaproject
was rejected by the Soviet leader Mikhail Gorbachev in the mid-1980s. But
in recent months it has won vocal support. Backers include Moscow's mayor,
Yuri Luzhkov, a possible successor to Vladimir Putin as Russian president,
alongside central Asian leaders and a growing number of Russian
scientists. One of the country's senior environmental scientists has told
New Scientist he has resumed research on the project. Thirsty crop
The proposed scheme would be roughly equivalent to irrigating Mexico
from the North American Great Lakes. It would drive a canal 200 metres
wide and 16 metres deep southwards for some 2500 kilometres, from the
confluence of the north-flowing rivers Ob and Irtysh, to replenish the
Amudarya and Syrdarya rivers near the Aral Sea The canal would carry 27
cubic kilometres of water a year. Though this is just seven per cent of
the Ob's flow it would bring 50 per cent more water to the lower Aral Sea
basin. The rationale behind the scheme is clear. Central Asian states
that were once part of the Soviet Union are economically dependent on
cotton, a notoriously thirsty crop. Today the region's two biggest
cotton-growing nations, Uzbekistan and Turkmenistan, have the highest per
capita water consumption in the world. Yet Turkmenistan says it intends to
double cotton production in the next decade. International plans to
kick-start the economy of northern Afghanistan, on the upper reaches of
the Amudarya, depend on taking as much as 10 cubic kilometres of water a
year from that river. With climate models predicting big decreases in
rainfall in central Asia, the International Crisis Group, an NGO based in
Brussels, Belgium, recently forecast water wars in the region. Already,
the Amudarya and Syrdarya, which once had combined flows greater than that
of the Nile, have been largely emptied by massive irrigation projects to
grow the cotton. As the rivers died, so has the Aral Sea into which they
drain. It has lost three-quarters of its water since 1960, leaving former
ports up to 150 kilometres from the receding shoreline, and a salty
wilderness where the sea used to be. Dilapidated and inefficient
Meanwhile, irrigation canals in Uzbekistan and Turkmenistan have
become increasingly dilapidated and inefficient. Few of the region's
50,000 kilometres of irrigation channels are sealed, so much of their
water goes to waste. According to a World Bank study, some 60 per cent of
water intended for farms does not reach the fields. Two years ago, while
on a visit to Putin in Moscow, Uzbekistan's president, Islam Karimov,
revived the idea of diverting Siberian rivers. "Although it seems
ambitious, it appears to be the only tangible solution to the ecological
and other problems caused by the drying of the Aral Sea," says Abdukhalil
Razzakov of the Tashkent State Economic University in Uzbekistan. Now,
after more than a decade without discussion of the project in Russia, it
is back on the table. This week, Igor Zonn, director of Soyuzvodproject, a
Russian government agency in charge of water management and ecology, told
New Scientist: "We are beginning to revise the old project plans for the
diversion of Siberian rivers. The old material has to be gathered from
more than 300 institutes." In January, Luzhkov visited Kazakhstan to
promote the plan. He says that central Asia would have to pay for the
water, but behind the scenes Moscow sees the scheme as a way to rebuild
its political and economic power in the region. It also wants to avoid a
collapse of its southern neighbours' economies, which could send a flood
of ecological refugees towards Russia. One-fifth of the population of the
Karakalpak region of Uzbekistan has emigrated since 1990. But, as in the
1980s, the scheme will be hugely controversial in Russia. The chairman of
the Siberian branch of the Russian Academy of Sciences, Nikolai Dobretsov,
has told New Scientist that the diversion "would threaten the Ob basin
with eco-catastrophe and socio-economic disaster", destroying fisheries
and upsetting the local climate. Efficiency gains Some
environmentalists support the scheme as a means to revive the Aral Sea.
But Oleg Vasilyev, a former head of the Institute of Water and Ecology
Problems, part of the Russian Academy of Sciences, who backs the plan,
says the water should be used primarily for irrigation, and so would never
reach the Aral. Central Asia now faces a choice: begin massive reforms
that will allow a more efficient use of water and less reliance on thirsty
crops like cotton, or buy in water from outside. Nikita Glazovsky, a
leading Russian geographer and former deputy environment minister under
Boris Yeltsin, says the region's engineers "still find it easier to divert
rivers than to stop inefficient irrigation". And reform has so far proved
beyond the leaders of central Asia, whose methods of government have
changed little since Soviet times. If Russia pursues the plan, the
global ecological repercussions are bound to loom large. In the 1980s,
western scientists feared that reducing the flows of north-flowing
Siberian rivers would damage the Arctic ice cap and upset global climate.
Now the tables have turned, and the worry is more about the increasing
flow caused by global warming. The Ob and nearby rivers pour seven per
cent more fresh water into the Arctic Ocean than 70 years ago, and climate
models indicate that flows could rise by up to 80 per cent by the end of
the century. The arrival of such large volumes of fresh water into the
Arctic Ocean could lead to a sudden breakdown of a global ocean
circulation system that ultimately drives the Gulf Stream, which keeps
Europe warm in winter. Such a breakdown could leave Europe facing a new
ice age as the rest of the planet warms. Work on the diversion project is
unlikely to begin soon, and it faces many financial, political, ecological
and design hurdles. But a project on this vast scale no longer seems
unthinkable. China's south-north project to take water from the Yangtze
river to the parched Yellow river is as large and expensive, and is under
way. Some observers believe that Putin might like to leave the canal as a
lasting symbol of his Presidency. According to Victor Brovkin, a Russian
expert in climate modelling, now at the Potsdam Institute for Climate
Impact Research in Germany, "If Putin wants to respond to Bush's plan to
go to Mars, this might be it."

ITAR-TASS / 08.02.2004
XXI century to be time of great
discoveries in life sciences XXI век станет
временем великих открытий в науках о жизни и энергии, считают
члены Российской академии наук.
|
MOSCOW, February 8 (Itar-Tass) -- The twenty
first century will be the time of great discoveries in life sciences and
energy. “Research in such fields as biotechnology, pharmacology and
molecular biology will open up new vistas in the practical medicine,” a
source in the Russian Academy of Sciences that celebrates in 280th
anniversary Sunday told Itar-Tass. Russian Science Day is marked on
February 8 since 1999 under a Russian presidential decree. According
to president of the Academy of Sciences Yuri Osipov “scientists will focus
attention on the live organism and live cell in the current century.”
Osipov believes that their study opens new opportunities for the
development of medicine. Russian scientists name nanotechnologies as
another priority. “Further successes in microelectronics, optics,
biotechnologies and creating radically new medicines are impossible”
without nanotechnologies, he emphasised. “Medicines affecting selectively
genetic programmes that are responsible for some or other diseases will be
used for treatment soon,” Academician Valentin Vlasov told Itar-Tass.
Energy will also change in the twenty first century. “The stocks of
natural resources of oil and gas are rapidly exhausting and their
restoration will take millions of years,” the source said. Meanwhile
“there are unique developments in hydrogen and thermonuclear energy in
Russia,” Academician Nikolai Ponomarev-Stepnoi told Itar-Tass. He recalled
that the international thermonuclear reactor project that became
international “was worked out and made the first steps for the practical
implementation in our country.” Meanwhile he is confident that “hydrogen
will be used sweepingly as an energy carrier for heating houses, car
engines and even children toys already in twenty years.” For his part,
Sergei Nikolsky, 98, the oldest Russian academician, believes that “the
main discoveries in the new century should be expected in biology and
physics.” “However without the state support many of them will not be put
into practice and probably remain on paper,” he told Itar-Tass. The
Russian Academy of Sciences was established by a decree of Peter the Great
on February 8 1724. At present the academy comprises of 400 research
institutes located all over the country, the Academy of Sciences presidium
said. 18 academy scientists were awarded with Nobel Prizes. Academician
Ivan Pavlov was the first Nobel laureate in 1904. The Nobel Prize was
bestowed on Academicians Vitaly Ginzburg and Alexei Abrikosov last year.

09.02.2004 French Academy chief greets
Russian academy on jubilee 8
февраля исполнилось 280 лет со дня основания Российской академии
наук. Постоянный секретарь Французской академии и иностранный член
РАН Элен Каррер д`Анкосс считает это событие большим праздником не
только для ученых, но и для всех просвещенных людей.

MOSCOW,February 9 (Itar-Tass) -- Secretary
of the French Academy of Sciences Helene Carrere d'Encausse believes that
the 280th anniversary of the Russian Academy of Sciences that was marked
on February 8 is a great holiday not only for scientists. Instituted
280 years ago in St. Petersburg by order of Tsar Peter I, the Russian
Academy of Sciences united the most brilliant and outstanding people from
all parts of Russia. The Academy's creation was not just a landmark in
Russia's intellectual history. It also gave the first opportunity to unite
the country's best intellectual forces for developing scientific life,
Helene Carrere d'Encausse told Itar-Tass in Russian on Sunday, February 8.
Helene Carrere d'Encausse is the permanent Secretary of the French
Academy of Sciences and a prominent expert on Russia who has written more
than ten books about this country. France attaches great importance to
cultural and scientific relations with Russia, Helene d'Encausse went on
to say. She added that Peter the Great who studied the French scientific
experience during his tour of France supplemented it considerably in his
decree on the institution of the Russian Academy of Sciences. Though
the French Academy was organized 400 years ago and still gathers together
the best scientists, it doesn't have scientific institutions or education
establishments and doesn't conduct any scientific research. Therefore,
Russia and France develop scientific and cultural cooperation through
direct contacts between their academicians. “It's a great honour for
me to be a foreign member of the Russian Academy of Sciences. I am very
proud of my membership,” Helene Carrere d' Encausse said in conclusion.

2004-02-25 Une ébauche de
décision finale sur l'ITER au mois de
mars Шесть участников проекта ITER (международный
экспериментальный термоядерный реактор), собравшиеся 21 февраля в
Вене, так и не пришли к окончательному решению, отложив его на
начало марта. |
Les délégations des six partenaires
participant à la négociation relative au site d'implantation du
réacteur thermonucléaire expérimental international (ITER)
se sont réunis à Vienne, en Autriche, le 21 février
dernier, sans toutefois parvenir à une décision commune.
D'après une déclaration commune de
la Chine, du Japon, de l'Union européenne, de la Russie, de la
République de Corée et des États-Unis, « les parties de
l'ITER poursuivront leurs discussions, y compris sur l'exploration prochaine
d'une approche de projet plus vaste de l'énergie de fusion. Toutes les
délégations ont réaffirmé leur engagement en faveur
d'un consensus sur une mise en ouvre conjointe de l'ITER»
Les partenaires ont convenu de convoquer une
réunion d'experts techniques début mars, principalement dans le
but de réaliser une analyse technique. Un porte-parole de la Commission
a confié à CORDIS Nouvelles qu'une réunion finale visant
à parvenir à une décision est également
prévue courant mars, mais qu'il faut encore trouver des arrangements.
Selon le porte-parole de la Commission, « les négociations sont toujours
en cours, mais aucune avancée importante n'a été
enregistrée au cours de la réunion de Vienne. L'Union
européenne reste convaincue de sa capacité à persuader les
autres partenaires de l'ITER de l'opportunité du choix de Cadarache
(France). Interrogé sur les informations laissant entendre que le Japon
serait prêt à mettre au point son propre réacteur si son
site de Rokkasho-Mura n'était pas sélectionné, le
porte-parole a déclaré à CORDIS Nouvelles: « Cette
affirmation n'a pas été confirmée officiellement. Il va de
soi que le Japon est libre d'agir de la sorte s'il le souhaite, mais l'UE
attendra la présentation officielle des intentions japonaises avant de
prendre position. »

17 février 2004 Le
Russie planche sur un nouveau vaisseau spatial Российские инженеры приступили к работе над проектом
нового космического корабля, по размерам и вместимости вдвое
превосходящим «Союз». |
MOSCOU (AP) -- Les ingénieurs russes ont commencé
à travailler sur le projet d'un nouveau vaisseau spatial qui serait deux
fois plus grand et spatieux que le Soyouz, a annoncé mardi le directeur
de l'Agence aérospatiale russe, Youri Koptev.
Le nouveau vaisseau pourra transporter au moins six astronautes et
possèdera une section habitable réutilisable, a
précisé M. Koptev lors d'une conférence de presse. Par
comparaison, le Soyouz, qui a été mis au point à la fin
des années 60, peut emmener trois cosmonautes et n'est pas
réutilisable.
Le vaisseau conçu par l'entreprise RKK Energiya aura un poids au
décollage de 12 à 14 tonnes, soit deux fois plus que le Soyouz.
M. Koptev a affirmé que le projet était bien avancé,
mais il n'a pas donné de délai pour la construction du vaisseau.
Il a précisé que le nouveau véhicule serait destiné
au vol orbital autour de la Terre.

UNIVERSITY OF DELAWARE /
2:25 p.m., Feb. 23, 2004 UD works with
Russian academy on terahertz technology Делавэрский университет и Российская академия наук
разрабатывают проекты устройств, испускающих терагерцевые сигналы.
Подобные устройства могут быть использованы в биохимии,
медицинской диагностике и раковых исследованиях.

The University of Delaware is working with
the Russian Academy of Sciences on a project to develop novel devices that
emit terahertz signals for applications in biochemical identification,
medical diagnostics and cancer research. The research is being conducted
at laboratories headed by James Kolodzey, professor of electrical and
computer engineering at UD, and Miron Kagan, director of the Russian
Academy's Institute of Radioengineering and Electronics, with funding
provided through the U.S. Civilian Research and Development Foundation
(CRDF). “This CRDF program achieves synergy by combining the scientific
strengths of the groups in St. Petersburg and Moscow in Russia with the
experimental abilities of the University of Delaware,” Kolodzey said. The
UD research team is recognized as an international leader in the
development of terahertz nanotechnology, last year announcing it had
discovered a means to harness the power of the terahertz frequencies in a
palm-sized device using a semiconductor nanostructure. Terahertz is
the final frontier in the study of electromagnetic waves, according to
Kolodzey, who said that in the frequency spectrum it lies between
microwaves and infrared light. It is 1,000 times higher in frequency than
microwaves, which are used in cell phones and ovens, and 100 to 1,000
times lower than visible light. Not much is known about the terahertz
frequencies, Kolodzey said, and the UD team's research is in both basic
science and in practical applications. It is known that the frequencies
are strongly absorbed by molecules in the atmosphere, which makes
terahertz a poor medium for long distance communication through the air,
which is how the microwave frequencies are used. However, terahertz is of
great value at closer ranges because of its strong interactions with
materials, which could provide opportunities in chemical diagnostics and
medicine. In informing Kolodzey about the grant award, U.S. Rep.
Michael Castle (R-Del.) applauded “the University of Delaware's commitment
to science and its efforts to collaborate with institutions abroad.”
