Research studies techniques for conservation and restoration of color photographs
The conservation and restoration of photographs is a topic that, in general, has not been very much researched. For example, in the case of coloured or illuminated photographs, there does not currently exist an appropriate methodology, given that it there is not sufficient information about their material characteristics and structure. view more (2009-11-06)
An exquisite container
In campy old movies, Lucretia Borgia swans around emptying powder from her ring into wine glasses carelessly left unattended. The poison ring is usually a confection of gold filigree holding a cabochon or faceted gemstone that can be broken to empty the ring's contents. It is invariably enormous - so large it is rather odd nobody seems to notice... view more... (2009-11-02)
LANL Roadrunner simulates nanoscale material failure
Very tiny wires, called nanowires, made from such metals as silver and gold, may play a crucial role as electrical or mechanical switches in the development of future-generation ultrasmall nanodevices. view more (2009-10-30)
Knocking nanoparticles off the socks

Water quality in orbit
Space is not a fun place to get a stomach bug. To ensure drinking water is adequately disinfected, University of Utah chemists developed a two-minute water quality monitoring method that just started six months of tests aboard the International Space Station. view more (2009-09-14)
Largest-ever collection of coins from Bar-Kokhba revolt found
The largest cache of rare coins ever found in a scientific excavation from the period of the Bar-Kokhba revolt of the Jews against the Romans has been discovered in a cave by researchers from the Hebrew University of Jerusalem and Bar-Ilan University. view more (2009-09-10)
Light at the speed of a bicycle and much more
The speed of light, 300 million metres per second, was long thought an immutable constant and has defined our understanding of matter and energy but recent research in the area of optics and photonics is proving that we can manipulate light to some ingenious and hugely lucrative ends. view more (2009-09-09)
Do the media lead entrepreneurs astray?
If you're looking for reliable information, then you won't necessarily find it in the newspaper. According to Dr. Susan Glover from the University of California in the US, public information from both informal and written sources, like newspapers, leads entrepreneurs astray. view more (2009-08-27)
New approach to wound healing may be easy on skin, but hard on bacteria
In a presentation today (Aug. 19) to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing. view more (2009-08-19)
Study: Cigarette packaging still misleading consumers over health hazards
New research suggests that current regulations have failed to remove misleading information from cigarette packaging, revealing that a substantial majority of consumers believe cigarettes are less hazardous when the packs display words such as "silver" or "smooth," lower numbers incorporated into the brand name, lighter colours... view more...

Nanophysics: Serving up Buckyballs on a silver platter
Scientists at Penn State University, in collaboration with institutes in the US, Finland, Germany and the UK, have figured out the long-sought structure of a layer of C60 - carbon buckyballs - on a silver surface. view more (2009-07-28)
New silver nanoparticle skin gel for healing burns
Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing. view more (2009-07-23)
Aerosolized nanoparticles show promise for delivering antibiotic treatment
Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance. view more (2009-05-20)
Blurring the Line Between Magic and Science: Berkeley Researchers Create an 'Invisibility Cloak'
The great science fiction writer Arthur C. Clarke famously noted the similarities between advanced technology and magic. This summer on the big screen, the young wizard Harry Potter will once again don his magic invisibility cloak and disappear. view more (2009-05-04)
Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. view more (2009-04-20)
Nano changes rise to macro importance in a key electronics material
By combining the results of a number of powerful techniques for studying material structure at the nanoscale, a team of researchers from the National Institute of Standards and Technology (NIST), working with colleagues in other federal labs and abroad, believe they have settled a long-standing debate over the source of the unique electronic... view more...

Tea tree oil and silver together make more effective antiseptics
In the fight against infected skin wounds, mixing tea tree oil and silver or putting them in liposomes, (small spheres made from natural lipids), greatly increases their antimicrobial activity and may minimise any side effects. view more (2009-03-30)
British butterfly reveals role of habitat for species responding to climate change
Most wild species are expected to colonise northwards as the climate warms, but how are they going to get there when so many landscapes are covered in wheat fields and other crops? view more (2009-02-25)

The phenomenon of light emission by living organisms, bioluminescence, is quite common, especially in marine species. view more (2009-02-23)
Facial expressions of emotion are innate, not learned, says new study
Facial expressions of emotion are hardwired into our genes, according to a study published today in the Journal of Personality and Social Psychology. The research suggests that facial expressions of emotion are innate rather than a product of cultural learning. view more (2008-12-29)
