Star trek criteria

19.02.2002


Interstellar travellers should be "motivated, tolerant and nice".


Star trekking: space voyagers should be one big family.

One hundred and sixty fertile, motivated, English speakers could make it to distant stars, researchers have worked out. But generations down the line, returning voyagers may speak an alien tongue.

Travel to planets orbiting other stars will soon be technically possible, the meeting of the American Association for the Advancement of Sciences in Boston heard last week. But the 200-year odyssey will require a certain kind of crew.


Sci-fi teams of frozen humans and cyborgs "didn’t seem likely to make it", anthropologist John Moore of the University of Florida in Gainsville told the meeting. Families, he reckons, are a better basis for long-term travel.

Moore has worked out the smallest group that could maintain a crew over 8-10 generations. Each person must have a choice of ten possible partners, his population simulation calculates. If women had children late in life, the crew could drop to 80.

Language of intergalactic love

Prospective couples should woo in English, said linguist Sarah Thomason of the University of Michigan in Ann Arbor. Global politics would probably dictate a multinational mix, but the current international language is the most obvious choice for conversation.

But if the journey takes 500 years, home and ship "won’t be able to talk to each other", Thomason predicts. Down-to-Earth words like ’horse’ and ’truck’ would have no meaning on board, and the slang of interstellar adolescents would diverge from Earth-speak. The crew would have to be beamed language lessons, Thomason said.

Temperament is also critical. "You want motivated, tolerant, nice people," said Moore. This should ensure future generations don’t lose interest in the mission and head for the nearest hospitable asteroid belt. Whether the band would actually get on would be more a matter of luck, the researchers conceded.

The exercise is not science fiction, explained space scientist Geoffrey Landis of the NASA Glenn Research Center, Cleveland. Several ways to reach other solar systems have been proposed in recent years. These include using a laser beam projected from Earth to push a vast space sail. Such a ship might travel at 30,000 kilometres per second - around a tenth of light speed.

"There’s actually been some testing done," revealed Landis: "Ultimately, this is going to happen." No one is taking crew applications yet, however.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
