Will medical nanorobots be biocompatible?

October 28, 2003

The second volume in the Nanomedicine book series by Robert A. Freitas Jr. , Nanomedicine, Vol. IIA: Biocompatibility, has been published by Landes Bioscience.

This comprehensive technical book is timely, given the growing concerns in the environmental community about the biocompatibility of nanotechnology.

It describes the many possible responses of the human body to the in vivo introduction of future medical nanorobots. Such advanced… read more

‘Perfect solar storm’ sends massive eruption Earth’s way

October 28, 2003

The third most powerful solar flare ever recorded erupted from the Sun earlier today, and scientists say Earth could feel the effects with communications disruptions and loss of power.

A major geomagnetic storm is expected to happen when it reaches us on October 29th or 30th.

“It was slightly more powerful that the famous March 6, 1989 flare which was related to the disruption of the power grids… read more

Man who lost bionic arm waits to be rebuilt

October 28, 2003

Advances in technology are making the fiction of the Bionic Man a reality.

One prototype developed by Edinburgh-based Touch EMAS is able to sense electrical currents from a person’s shoulder muscles. Microchips can then translate them into specific movements of its joints.

Scientists at Duke University said this month that brain implants allowing severely disabled people to control prosthetic limbs with their minds could be ready for use… read more

Smart Dust Collecting in the Enterprise

October 28, 2003

Smart Dust — cubic millimeter-sized sensors, or “motes” — is making its way from the research labs and into the enterprise, courtesy of companies like Intel.

It combines radio frequency communication technology and MEMS to monitor situations where humans may not be able to go.

The Galactic Civilizations: Part V

October 27, 2003

“There’s no logical reason to believe that machine intelligence won’t, in fact, inherit the Earth, and perhaps inherit the Universe,” said cosmologist David Grinspoon, referring to Ray Kurzweil’s idea of the coming merger of human and machine.

“And you can certainly imagine, even if it doesn’t happen here, that on some planet intelligent machines have been created which are effectively immortal. In fact, I think that it’s hard to… read more

Silicon May Have Been The Key To Start Of Life On Earth

October 27, 2003

A scientist at the University of Sheffield has discovered that silicon may have been the key to the establishment of life on earth.

In a paper, due to be published in the International Journal of Astrobiology, Dr Wainwright outlines his team’s discovery that silicon stimulates bacterial growth when food is in short supply, even in the absence of oxygen.

Scientists discover largest structure in universe

October 27, 2003

Scientists have discovered the largest structure yet found in the universe, a “Great Wall” of galaxies 1.37 billion light-years long, according to an article in Science, Oct. 24, 2003.

This cosmic ribbon dwarfs anything seen before by more than 600 million light-years. The wall’s vastness pushes the limits of existing cosmological theories.

Orgasmatron Puts Tech in Sex

October 27, 2003

A Texas company claims to have invented a kind of Orgasmatron for women — an electrical stimulation device that takes women to a pre-orgasmic state.

Methuselah Worm Remains Energetic for Life

October 27, 2003

Researchers report in the current issue of the journal Science that variants of the simple worm C. elegans can live 124 days–the equivalent of a human reaching his 500th birthday.

The researchers perturbed genes in C. elegans that affect the activity of insulin and removed gonad tissue, which affects endocrine hormone levels. Worms treated this way lived six times longer than normal worms and remained active for most of… read more

Is grid computing finally a reality?

October 27, 2003

As Oracle prepares to launch “grid-enabled” versions of its database and application server, are we any closer to a computer grid, which promises the self-diagnostic and self-healing capabilities that computer companies and their customers have sought for so many years?

Oracle’s new products do exhibit some features of self-healing and self-tuning, but a homogeneous grid is still a long way off.
