Leaving Computers On Helps Them Last Longer
You take a deep breath, rub your tired eyes and prepare to push away from your personal computer after a lengthy instant message exchange, video viewing or analysis of your monthly budget--maybe all three. But before you exit cyberspace, a decision must be made: Should you shut the machine down, place it into "sleep" mode or do nothing at all?

Religion vs. science vs. politics
Science editor Alan Boyle's blog: The holiday season typically sparks plenty of reflection on the interplay between religion and science. Not this year, though.

Why is Indonesia withholding samples that could track the virus's evolution and help produce a vaccine?
Indonesia has been hit by more human deaths from the H5N1 bird-flu virus than any other country, yet it refuses to share its virus samples with the World Health Organization (WHO).

Exchange rate hits US researchers
The weak dollar is affecting US researchers working abroad and threatens American involvement in flagship projects say physicists at the CERN laboratory. Grants paid in dollars to researchers in Europe are now worth substantially less than they were a year ago.

Congress Fails Science
The U.S. Congress has long been a slow and irresolute institution, especially when it comes to science issues. Unfortunately, the Democratic majority that came to power in the 2006 midterm election has so far done little to change that reputation.

Quicky Assembled Bamboo Bridge, Strong Enough For Trucks, Opens In China
In China, bamboo is used for furniture, artwork, building scaffolding, panels for concrete casting and now, truck bridges. The sustainable design is the first of its kind: the 10-meter span in Hunan province was assembled in days without heavy equipment and easily carries 8-ton vehicles.

Storing light with sound
The information in a beam of light can be stored for a while by converting it into a sound signal, then reading it back out again as light, researchers have found. The process, which can be done in commercially-available optical fibres, could be used to help make computer processing more efficient in future.

New technique could dramatically lower costs of DNA sequencing
Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably.

'Retrospective rubber' remembers its old identities
The material, described in the journal Advanced Materials, forms a new class of shape-memory polymers, which are materials that can be stretched to a new shape and will stay in that form until heated, at which time they revert to their initial shape.

Prospecting for Power
Last week, a pair of geochemists published a report in Science showing that the ultrasensitive detection of traces of helium at the surface using mass spectrometers may hold the key to sniffing out the best sites of this hidden heat.

Intel Looks Beyond Silicon
Intel has developed a new kind of transistor, made of a material other than silicon, that has the potential to be faster and use less electricity than today's chips. And, crucially, the new transistors are economical and could be fabricated using existing manufacturing facilities because they can be built directly on top of standard silicon wafers.

New chemistry and microsurfaces have led to super oil-repellent materials that are self-cleaning
Researchers have made materials that repel oil and are able to clean themselves without the help of soap and water. What's more, the researchers describe exactly how the materials work, which could help others design similar materials. This could lead to a range of applications, including fingerprint-shedding cell-phone displays.

Life's Complexity Began With Poop
Every now and then, science puts forth a theory that -- at least on a bitterly cold December day, with a flu infection stirring fatigue in a certain science journalist -- resonates with grand poetic truth. The theory: the incredible complexity of life on Earth, the myriad of forms and forms and functions, owes its existence to poop.
