Oceans teeming with 10 million kinds of microbe

August 2, 2006

The diversity of microbes living in the world’s oceans may be more than 100 times greater than previously estimated, according to researchers working on the International Census of Marine Microbes, part of the Census of Marine Life.

Chinese spacecraft dock in orbit

November 3, 2011

Shenzhou 8 craft made contact with Tiangong-1

The unmanned Shenzhou 8 craft, launched earlier this week, has made contact with the Tiangong-1 space lab.

Being able to dock two space vehicles together is a necessary capability for China if it wants to start building a space station towards the decade’s end.

No astronauts were in the Shenzhou craft this time, but future missions will carry people.

Closest asteroid yet flies past Earth

October 3, 2003

An asteroid about the size of a small house passed just 88,000 kilometres from the Earth on Saturday 27 September — the closest approach of a natural object ever recorded.

Designing highways the slime mould way

January 11, 2010

(University of the West of England)

A slime mold colony was able to create an efficient real inter-city road network for the UK, mimicking the actual road network, specialists in unconventional computing at the University of the West of England have found.

Intel unveils ‘Atom’ chip at Taiwan tech show

June 4, 2008

Intel Corp. on Tuesday unveiled a new processor it says will revolutionize the information technology industry by powering small laptops at low cost.

New Chip Design Promises Terahertz Processors

August 18, 2006

Scientists at the University of Rochester have come up with a new “ballistic computing” chip design that could lead to 3-terahertz processors that produce very little heat.

The Ballistic Deflection Transistor (BDT) bounces the electrons into their chosen trajectories. Using inertia, it functions more as an intersection for electrons than as a device that expends energy to stop and start them. Because of this approach, far less power is… read more

Data Faster Than Speeding Bullet

October 15, 2003

Two major scientific research centers, CERN and Caltech, said they have set a new world speed record by sending 1.1 terabytes of data across the Internet at 5.44 gigabits per second.

Deriving the Properties of the Universe

January 18, 2010

The properties of the Universe can be derived by thinking about the origin of complexity, says a new theory by University of California, Berkeley and Stanford University physicists.

But, just like the anthropic principle, it also has the scent of circular reasoning about it: the universe is the way it is because if it were different, the complexity necessary to observe it wouldn’t be here to see it.

Researchers Design Band-Aid-Size Tactile Display

June 9, 2008
(Ig Mo Koo, et al.)

Researchers from Sungkyunkwan University in Korea and the University of Nevada have developed a flexible tactile display that can wrap around the fingertip, palm, or arm.

The key material in the display is an electroactive polymer that can stimulate the skin. It consists of eight layers of dielectric elastomer actuator films sprayed with electrodes in a specific pattern.

The soft display might provide a means of… read more

Bacteria put new spin on micromotors

August 30, 2006

Japanese researchers have used motile bacteria to rotate a microscopic motor made from silicon. The team believes that their system — fuelled by glucose — is the first micromechanical device to integrate inorganic materials with living bacteria.

New way to target — and kill — proliferating tumors

November 16, 2011

Cheresh antitumor

Researchers at the University of California, San Diego School of Medicine and the UC San Diego Moores Cancer Center have identified a new drug-discovery approach enabling the destruction of the most highly proliferative tumors, pointing to an effective, alternative method for killing fast-growing cancer cells without causing some of the negative effects of current therapies.

The scientists, led by David A. Cheresh, PhD, professor 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.

IPCC’s Himalayan glacier ‘mistake’ not an accident

January 25, 2010

The unsubstantiated Himalayan-glacier melt figures contained in a supposedly authoritative 2007 IPCC report on climate warming were used intentionally — despite the report’s lead author, Murari Lal, knowing there were no data to back them up.

“Lal last night admitted [the scary figure] was included purely to put political pressure on world leaders,” The Sunday Mail article reported.

Before the beginning

June 13, 2008

Caltech scientists have developed new models of the universe that account for the recent finding that temperature variations in the cosmic microwave background radiation over half the sky appear to be about 10 percent greater than the variations in the other half.

In one scenario, the universe existed before inflation — the short-lived but enormous growth spurt associated with the Big Bang. In the other scenario, the universe is… read more

Electric jolt triggers release of biomolecules, nanoparticles

September 12, 2006

Johns Hopkins researchers have devised a way to use a brief burst of electricity to release biomolecules and nanoparticles from a tiny gold launch pad. The technique could someday be used to dispense small amounts of medicine on command from a chip implanted in the body. The method also may be useful in chemical reactions that require the controlled release of extremely small quantities of a material.

For their… read more
