Could a hole in space save man from extinction?

January 11, 2005

In the next decade, powerful satellites will help us to understand life, the fate of our universe and the “theory of everything,” says Michio Kaku.

  • In 2014, the Terrestrial Planet Finder satellite will begin to hunt for small, Earth-like planets in 500 star systems with a telescope designed to screen out the mother stars, whose light otherwise overwhelms the faint radiation from any nearby planets.

    Could a Blu-ray disc improve solar-cell performance?

    December 12, 2014

    It was rated of one of the 25 worst movie conversions to Blu-ray. But never mind that. A Teen Wolf Blu-ray disc will work just as fine in improving your future solar collector. (Credit: 20th Century Fox Home Entertainment)

    Here’s an idea: recycle that old grade-B movie Blu-ray disc to improve your future solar collector. Well, sort of. It turns out the Blu-ray data storage pattern when used with a solar collector increases light absorption by 21.8 percent, according to new research from Northwestern University, thanks to Blu-ray discs’ quasi-random pattern and high data density.

    The researchers tested a wide range of movies and television shows stored on… read more

    Couch potato lifestyle may speed up ageing

    January 29, 2008

    Researchers at St. Thomas’ hospital in London have found that people who did not exercise in their spare time had shorter telomeres than very active people.

    Telomeres shorten each time a cell divides, and when they become too short a cell can no longer divide, so telomeres act as a kind of timer counting down our biological age.

    Exercise can help, but it only seems to help with… read more

    Cosy social networks ‘are stifling innovation’

    August 5, 2009

    Today’s software developers work in social networks in which everyone is closely linked to everyone else, says social scientist Viktor Mayer-Schonberger of the National University of Singapore.

    “The over-abundance of connections through which information travels reduces diversity and keeps radical ideas from taking hold,” he suggests.

    Cost of gene sequencing falls, raising hopes for medical advances

    Human genome sequence

    In Silicon Valley, the line between computing and biology has begun to blur in a way that could have enormous consequences for human longevity.

    Bill Banyai, an optical physicist at Complete Genomics, has helped make that happen. His digital expertise was essential in designing a factory that automated and greatly lowered the cost of mapping the three billion base pairs that form the human genome.

    Cost of evolution runs into billions

    September 14, 2001

    Humans are causing evolution on a grand scale – and it is costing us hundreds of billions of dollars each year, says a Harvard biologist.Every time a strain of bacteria becomes resistant to an antibiotic, or a weed mutates so it can thrive after being sprayed with a herbicide, there is a financial cost to humankind, Stephen Palumbi points out. He estimates that cost to be at least $100 billion… read more

    Cost of Decoding a Genome Is Lowered

    August 11, 2009

    Stanford engineer Stephen R. Quake has invented a new technology for decoding DNA and used it to decode his own genome for less than $50,000.

    Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists

    February 1, 2011

    Applying Bayesian model averaging to various cosmological models of the universe, astrophysicists at the University of Oxford and Imperial College London have found that the most likely model is that the Universe is flat.

    A flat Universe would also be infinite and their calculations are consistent with this too. These show that the Universe is at least 250 times bigger than the Hubble volume (similar to the size of… read more

    Cosmologists ‘see’ the cosmic dawn

    February 11, 2009

    Images that show the “Cosmic Dawn” — the formation of the first big galaxies in the Universe 590 million years after the Big Bang — have been produced by scientists at Durham University’s Institute for Computational Cosmology.

    The work combined a massive simulation showing how structures grow in dark matter with a model showing how normal matter, such as gas, behaves to predict how galaxies grow.

    Cosmologists Predict A Static Universe In 3 Trillion Years

    May 24, 2007

    Case Western Reserve University and Vanderbilt University physicists predict that trillions of years into the future, the information that currently allows us to understand how the universe expands will have disappeared over the visible horizon.

    What remains will be “an island universe” made from the Milky Way and its nearby galactic Local Group neighbors in an overwhelmingly dark void.

    Cosmologists ponder the puzzle of black rings

    May 6, 2009

    Masashi Kimura at Osaka City University in Japan has looked at the possibility of black rings — a variant of black holes — or other shapes forming in higher dimensional space.

    Cosmologists aim to observe first moments of universe

    February 17, 2009

    During the next decade, the South Pole Telescope will study the cosmic background radiation to test the validity of inflation theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the universe in a big bang.

    Cosmo Wenman’s mind-blowing 3D-printed sculptures

    Cosmo Wenman is a California artist who has just reminded us not to limit our imaginations when it comes to what can be made, MakerBot Blog reports.

    The horse head and human bust you see here were made entirely of MakerBot PLA Filament (White) on the original MakerBot Replicator.

    Cosmic web imaged for the first time

    Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing, for the first time, part of the network of filaments thought to connect galaxies in a cosmic web.

    Researchers at the University of California, Santa Cruz led the study, published January 19 in Nature.

    Using the 10-meter Keck I Telescope at the W. M. Keck Observatory in Hawaii, the researchers detected a… read more

    Cosmic ‘train wreck’ defies dark matter theories

    August 20, 2007

    Disturbing evidence has emerged from the wreckage of an intergalactic pile-up suggesting that the already mysterious substance known as dark matter may be even less well understood than astronomers thought.

    The observations come from a massive galaxy cluster called Abell 520 that lies 3 billion light years away. Abell 520 turns out to hold a massive dark core, empty of bright galaxies.

    The observation may rule out the… read more
