Sticky dust fingers the culprits
EMBARGOED UNTIL WEDNESDAY 5 NOVEMBER 19:00 HRS GMT NANOPARTICLES could give police the clearest fingerprints yet. Officers search for prints by dusting a crime scene with fluorescent powder. This sticks to the oily residue left by the fingertip, showing up the whorls and ridges. But sometimes the prints are not clear enough to finger a suspect.... view more... (2003-11-05)
Sensorial evaluation of the freshness of fish
AZTI has drawn up some 40 tables for freshness specific for the most important commercial species in southern Europe, including fish and shellfish. The sensorial method, known as QIM (Quality Index Method) and introduced into Europe some years ago, is being applied to a greater number of species, including some in the frozen state. Concretely, for... view more... (2005-04-18)

Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic foams. The surface of the ceramic is impregnated... view more... (2002-09-11)
Dating Of The Turin Shroad Was Incorrect
The researchers were allowed a single chance to examine the Turin Shroud. On April 21, 1988 a small piece, its square being about 7 square centimeters, was cut off from the Shroud under the supervision of Cardinal Anastacio Ballestrero, the Archbishop of Turin, and the invited experts. The sample was divided into smaller fragments, which were sent... view more... (2002-04-02)

The Prestige oil spill caused changes in the cell structure of mussels
The oil spill from the Prestige petroleum oil tanker in 2002 caused serious damage to the ecosystems in the Bay of Biscay. A PhD thesis at the University of the Basque Country (UPV/EHU) has studied the consequences of this spill for the mussels inhabiting this northern coast of the Iberian peninsula. view more (2009-03-25)
Revolutionary technology bringing fish to the desert
The world-first project will help to provide people living in barren regions with a vital source of protein and a valuable, if unlikely, cash crop. The intensive fish-growing system being developed can be set up anywhere in the world. Environmental geochemist Michael Krom is co-ordinating the £600,000 international project, which aims to... view more... (1999-02-12)
Bleak Times For The Orange Roughy
A committee of high-level marine scientists are calling for an immediate drop in fishing effort on deep sea stocks such as the orange roughy. According to a report which is released by ICES today (11 June), most deep sea fish stocks are being overfished. Scientists are recommending that not only should existing fishing pressure be reduced but... view more... (2004-06-10)

Plant-derived omega-3s may aid in bone health
Plant-based omega-3 polyunsaturated fatty acids (PUFA) may have a protective effect on bone health, according to a team of Penn State researchers who carried out the first controlled diet study of these fatty acids contained in such foods as flaxseed and walnuts. view more (2007-02-20)
FATTY FISH CONSUMPTION COULD REDUCE PROSTATE CANCER RISK
Consumption of fatty fish such as salmon, herring, and mackerel could reduce the risk of prostate cancer, report the authors of a research letter in this week's issue of THE LANCET.
