Red kiwi poised to make a healthy debut
First there was green, then yellow and now red-fleshed kiwifruit. A team of researchers in Italy and New Zealand has found that a newly developed variety of red-fleshed kiwifruit contain anthocyanins, bright red pigments that are highly potent antioxidants. view more (2005-11-10)
Traits produced by melanin may signal the bearer's capacity to combat free radicals
Some animal species have developed conspicuous traits produced by melanin pigments (for instance, dark manes in lions, black stripes in some birds and fishes). view more (2008-10-06)
New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen. view more (2005-08-10)
Laser treatment restores art
FIRING laser beams at priceless paintings might seem the height of folly, putting the painting`s delicate pigments at risk. So while conservators have for decades used ultraviolet lasers to clean up grubby sculptures, they have always fought shy of using them on soiled paintings. But now a study... view more (2002-09-25)
Faster Test For Checking The Efficiency Of The Paints Used As Protection Against Corrosion In The Automotive Industry
Researchers from the Area of Materials Science and Metallurgical Engineering at the Universitat Jaume I (UJI), Spain, have devised a quicker method to evaluate the systems used in the automotive industry to protect the metal chassis of vehicles against corrosion. This new technique allows the time... view more (2004-07-14)
Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using... view more (2005-10-11)
Oldest complex organic molecules found in ancient fossils
Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures - the oldest such molecules yet found. view more (2006-10-26)
QUT researcher discovers Maya mask splendour
Ancient Mayan temple builders discovered and used lustrous pigments to make their buildings dazzle in the daylight, a Queensland University of Technology researcher has discovered. view more (2008-01-23)
Eat junk, look good, die young
Natural Environment Research Council and University of Glasgow Press release: A study published today by Glasgow University scientists shows that finches given a poor diet briefly in early life become adults that can't cope with ageing. Birds that had a low quality diet for just two weeks grew into... view more (2003-06-27)
Researchers visualize complex pigment mixtures in living cells
In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria. view more (2008-03-05)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in... view more (2001-11-26)
New study uncovers secrets behind butterfly wing patterns
The genes that make a fruit fly's eyes red also produce red wing patterns in the Heliconius butterfly found in South and Central America, finds a new study by a UC Irvine entomologist. view more (2007-10-26)
Paint used by Dutch masters turns into rat poison
The painters Willem Kalf, Jan Davidsz. de Heem and Balthasar van der Ast are particularly famed for their bright yellow orpiment ("royal yellow"). The researchers have shown that light causes a chemical reaction in this yellow which separates the sulphur and the arsenic. The sulphur is released... view more (1999-05-17)
Synchrotron light unveils oil in ancient Buddhist paintings from Bamiyan
The world was in shock when in 2001 the Talibans destroyed two ancient colossal Buddha statues in the Afghan region of Bamiyan. view more (2008-04-22)
NYU Researchers id new class of photoreceptors,pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of... view more (2008-04-22)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
Laser probe of a brain pigment's anatomy may offer insight into Parkinson's disease
In a finding that may offer clues about Parkinson's disease, a team led by Duke University researchers used a sophisticated laser system to gain evidence that a dark brown pigment that accumulates in people's brains consists of layers of two other pigments commonly found in hair. view more (2006-09-26)
The science behind why leaves change colour in the Autumn
Autumn is marked out by spectacular changes in leaf colour as the greens of summer change into the yellows and reds of autumn. In parts of North American whole tourist industries are based on this change, but why do leaves turn these bright colours before falling off the trees? view more (2004-10-04)
Why Do Autumn Leaves Bother to Turn Red?
Soils may dictate the array of fall colors as much as the trees rooted in them, according to a forest survey out of North Carolina. view more (2007-10-26)
Unravelling the threads of history at the ESRF
An international team of scientists from Israel, Germany and the United Kingdom has recently been working at the ESRF in order to unravel the threads of history. Wrappings of the famous Dead Sea Scrolls have been studied with synchrotron light. The X-rays will hopefully provide the team with... view more (2004-03-25)
On the Energy Trail: Berkeley Researchers Find New Details Following the Path of Solar Energy During Photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. view more (2008-04-28)
Student scientists create living bacterial photographs
Using Petri dishes full of genetically engineered E. coli instead of photo paper, students at The University of Texas at Austin and UCSF successfully created the first-ever bacterial photographs. view more (2005-11-28)
Researcher turns brown algae phylogeny upside down
According to fellow phycologists, algae expert Stefan Draisma from the Leiden University has turned brown algae phylogeny completely upside down. His research shows that few of the currently assumed relationships between the orders are correct. Furthermore, it transpires that some simple species... view more (2002-06-24)
Smoking related to long-term risk and progression of age-related eye disease
Smokers appear to have an increased long-term risk and greater progression of the eye disease age-related macular degeneration. view more (2008-01-15)
Intelligent materials
The technology centre GAIKER of the Basque Country is working on a project whose aim is to develop intelligent polymers and discover their opportunities. Similarly, it will study the possibilities to introduce those polymers in the existing structures in order to promote their applicability and to... view more (2002-10-02)
