Technology: In DSpace, Ideas Are Forever
The libraries at the Massachusetts Institute of Technology are earnestly bookish (2.6 million volumes and 17,000 journals) but increasingly digital (275 databases and 3,800 electronic journals). And just as e-mail dealt a blow to snail mail, digital archives are retooling scholarly exchange. A number of universities, from the California Institute of Technology to M.I.T., are creating ”institutional repositories” designed to harness their own intellectual output. M.I.T.’s archive, perhaps the most ambitious, is called DSpace (

Scholarly Storage: Traditionally, journals make research public after peer review, which can take months, sometimes years. Archives like DSpace, however, collect unpublished work — documents of any length, lecture notes, photos, videos, computer simulations, blueprints, software — in all disciplines and make most of it available to anyone as soon as it’s received.

Steam power takes to the road again
To the engineers and steam buffs gathered in the auditorium, most of the images in Roger Waller’s video were familiar enough – the gleaming bulk of a black locomotive standing in Waller’s workshop, a small loco climbing a precipitous mountain railway, an elegant paddle steamer crossing the blue waters of a Swiss lake. What caused a ripple of surprise, though, was a short sequence near the end. It showed a small green car with a round silver tank zipping along a Swiss road, its twin exhausts puffing out clouds of white vapour.

Waller is a modern steam pioneer. Along with a team at his engineering company DLM in Schaffhausen, northern Switzerland, he has spent the last decade redesigning and modernising steam locomotives to make them far cleaner, and more profitable, than “old steam”.

Cancer treatment: Sharp shooters
Radiation treatment helps to control cancer. With types of beams unlike traditional X-rays, the hope is to reach tumors more precisely with more lethal force and to have less effect on healthy tissue that is next to a tumor. Charged particles such as carbon ions might be the answer. Facilities around the world have treated around 12,000 people with carbon ions. The particles need to be accelerated to around 70% of the speed of light and shot with great precision at a person’s tumor.

Beautiful Bioimages for the Eyes of Many Beholders
A handful of image-sharing databases and software systems is becoming available, and these images might change the way biologists look at their own and other researchers’ data–if several obstacles can be overcome. Aside from the technical difficulties of creating user-friendly databases and interconnected networks of images in the scientific literature, there are pesky legal and ethical questions, such as ownership and credit.

Will glossy watermarks conquer fraud?
Ordinary office printers could create documents with a “watermark” that cannot be photocopied. Its inventors say the technique will make counterfeiting more difficult, but others argue that its very simplicity makes it of little use in fighting forgery.
Researchers at Xerox laboratories in Webster, New York, made the discovery while studying why images made by laser printers sometimes show glossy patches. …

Max Planck Takes an E-Publishing Plunge
Germany’s Max Planck Society, which runs the country’s flagship network of 80 research institutes, is about to launch a publicly accessible electronic publishing center that will enable its scientists to post published papers–and findings before they are peer-reviewed. The center will also develop new tools for information dissemination and electronic management, and negotiate on behalf of all the institutes to cut deals for cheaper access to electronic journals.

Telecommunications seeks its guiding light
“Pipe it in!” That’s the battle cry in telecommunications these days. The more information that can travel down an optical fiber-whether as phone calls, video games, movies, or symphonies-the better. Now MIT researchers in materials science, physics, and electrical engineering and computer science have collaborated to create a device that could dramatically increase the carrying capacity of optical fibers. The device, a “photonic bandgap microcavity resonator,” uses a microcavity, or defect, in a material called photonic crystal to guide the behavior of photons in much the same way that defects in a semiconductor can be used to control electrical properties.

Next generation sequencing: The genome jigsaw

Nanopores: a sequencer in your backpack
Genome sequencing can now be done anywhere: in the lab, in the field, perhaps even automatically with sensors. If a sequencer is so small it fits in the palm of your hand, then sequencing everywhere and anywhere becomes a possibility. Data analysis is still necessary, though. Here, it’s all about squiggle plots. There’s software to help weave through the squiggles.

Cancer genomes: discerning drivers from passengers
A tumor is not born as a diseased tissue with many mutations; rather, these mutations accumulate over time. Driver mutations give a tumor a tiny growth advantage, which may be as low as an estimated 0.4%. Finding which drivers play a role in cancer might get easier now that there are data mountains from large-scale cancer genome sequencing projects. But it is still a ways to a comprehensive cancer gene variant catalog.

Tracking metastasis and tricking cancer
Engineering approaches are letting scientists observe tumour cells to see how they detach from one spot and attach at another, and how they creep through tissue that should be too dense to let them pass. Other approaches involve scooping migrating tumour cells out of the blood and locking them in highly engineered cages to discover how they seed secondary tumours.

High-security labs: Life in the danger zone
Some microbes are deadly. Working with them in a research environment takes many precautions. And scientists have to find a way to maintain instruments that cannot be removed from the lab, once they are placed under bio-containment. A new high-security lab is opening up in Frederick, Maryland, a stone’s throw from the storied US Army Medical Research Institute of Infectious Diseases (USAMRIID). The proximity is intentional.

Circumcision: To cut or not to cut?
Imagine a quick and simple surgical procedure that trials have shown could give your newborn child lifelong protection against HIV and may ward off sexually transmitted diseases and cancer too. It involves a little pain and bleeding, and occasionally goes wrong, but the risk of serious adverse effects is tiny. Would you have it done? Chances are you would. But what if you found out that other trials have called the procedure’s benefits into question, and that it involves cutting off part of your child’s penis. Now how do you feel about it?

This, in a nutshell, is the dilemma facing the parents of newborn baby boys. According to the increasingly vocal advocates of male circumcision, slicing off the foreskin is one of the most effective public-health measures ever invented and should be done routinely, like vaccination. Not so fast, say opponents. They insist that circumcision has no medical benefits.

Marine biology – Geoengineering – Business
Scientific, Oct. 7, 2002
The little plankton that could? Maybe.
No one knows whether fertilizing single-celled marine organisms is a sound way to pull more heat-trapping carbon dioxide out of the atmosphere. But that hasn’t stopped companies from developing plans to do so. Slowing global warming is a big job. But some researchers and companies say that job could be done by enlisting the help of small but fantastically numerous–and collectively mighty–marine unicellular organisms called phytoplankton.

Phytoplankton make up the chlorophyll-bearing canopy at the base of the marine food web. As part of the natural biogeophysical cycle, phytoplankton absorb atmospheric carbon dioxide, a heat-trapping gas implicated in global climate change. Some of the carbon is buried when phytoplankton die and settle to the sea bottom.

In theory–one strengthened by some experiments, including one early in 2002–fertilizing phytoplankton could accelerate this natural process, sinking carbon in gigaton quantities. Companies see opportunities. The scientific jury is out on whether such a grand-scale experiment with complex atmospheric processes would work to pull out additional carbon–and if it did, whether the cascade of subsequent effects would ultimately wreak more environmental havoc than the excess carbon would in the first place.

Von Fischen und Frauen
Ein Abgeordneter des amerikanischen Kongresses wollte es ganz genau wissen: “Wenn diese Fische so viele Gene haben, wieso sind sie nicht klüger als wir?”, hatte er bei einer Anhörung gefragt. Die lakonische Antwort von Bob Baker, Physiologe an der New-York-Universität: “Manche von ihnen können es durchaus mit manchen von uns aufnehmen.”

“Wunderschön ist er”, schwärmt Mary Mullens an der Medical School der Universität Pennsylvania von einem Fisch, der in den führenden Labors als begehrter Modellorganismus und neuer Forschungsliebling gastiert. Der ursprünglich im indischen Ganges beheimatete Zebrafisch schwamm sogar in das Wall Street Journal, da Pharmafirmen nunmehr in ihn investieren. Denn er ist für genetische Studien ebenso geeignet wie für entwicklungsphysiologische Experimente. “Beim Zebrafisch”, so die Wissenschaftshistorikerin Evelyn Fox Keller, “passen die verfügbaren Techniken zu den aktuellen Fragen, und die Fragen passen zum Organismus: eine Konvergenz vieler Interessen und Möglichkeiten.”

A doggie bag of drugs
In days gone by, a badly behaved pet dog would probably have been sent to obedience classes for retraining. If it continued to misbehave, a one-way trip to the vet beckoned. But a society that believes that there is (or ought to be) a pill for every ill was unlikely to put up with this state of affairs for ever.

So it is probably not surprising that America’s Food and Drug Administration (FDA), the organisation charged with making sure that drugs destined for American people are safe and effective, has just given its first formal approval for two drugs to be used to treat the behavioral problems of American dogs.

E-Mail Mentoring Gets Test in German Rust Belt
Unemployed Youth, Volunteer Mentors Sign Up on Web; Program Sets Up Matches
He is 18, untrained and unemployed. But Daniel Jepass has a career goal: network administrator. “That’s what my telementor is,” he says.

In a special Internet café set up by the local employment agency in the hard-hit German rust-belt town of Bottrop, disadvantaged youths from the ages of 17 to 25 are placed in targeted one-year job training program, receive advice from on-site guidance counselors—and cyber-advice from so-called telementors.

Less than a third of Bottrop students find a prized apprenticeship position when they leave school—at 14, 15 or 17, depending on the type of school. Subsidized programs for those between the ages of 20 and 25 have brought unemployment down to 8.5% for that group, but general unemployment is at an unwavering 16.9%, and the rate for those under 20 is 14.2%.

These are typical figures for this densely populated area of western Germany stressed by Strukturwandel, the economic transition to post-industrial society. This is no Silicon Valley—years after the mines closed and the steel industry left, new employers arrive only haltingly.

Google-Chef Eric Schmidt: Das gesamte Leben wird zu einer historischen Akte / Online-Gemeinschaften verändern Wirtschaft und Gesellschaft

Als Eric Schmidt zum Einstellungsgespräch bei Google eintraf, hatten die Firmengründer Larry Page und Sergey Brin sein Foto und seinen Lebenslauf auf ihren Computerbildschirmen und an die Wand projiziert. Diese soziale Umgangsform habe Schmidt ein wenig überrascht, sie sei aber nunmehr an der Tagesordnung, sagte der promovierte Informatiker, der im März 2001 den Zuschlag als Google-Vorstandschef erhalten habe.

Soziale Netze, etwa Youtube mit seiner Videothek für alle, oder Online-Gemeinschaften wie Myspace und Facebook verändern nicht nur Umgangsformen, sondern viele Facetten von Wirtschaft und Gesellschaft, sagte Schmidt während des Personal Democracy Forums in New York.

Im “Social Networking” trifft man sich online, um Blogs, also Onlinetagebücher, zu betreiben, Informationen und Fotos herumzuzeigen, Youtube-Videos auszutauschen oder um sich politisch, kulturell, sozial und wirtschaftlich zu organisieren. Klarer Marktführer ist dabei Myspace. Laut Hitwise, einem amerikanischen Marktforschungsunternehmen, erreicht Myspace derzeit einen Social-Networking-Marktanteil in den Vereinigten Staaten von 79,7 Prozent, gefolgt von Facebook mit 11,47 Prozent. Danach folgen kleinere Seiten, darunter Bebo, Imeem und
