Speedy illumination


Fish remains are a good source of bioplastics. Jellyfish, meanwhile, could soon be an unlikely ally for police officers up and down the country.

All thanks to Chinese-British researchers who have discovered that a fluorescent protein contained in the slimy sea-dwellers could be a big help at crime scenes.

The protein binds with negatively-charged molecules in the grease and sweat found in fingerprints.

The team’s delicate water-soluble protein spray, developed in two colours, prevents smudging and illuminates prints under blue light within a matter of seconds. Even on rough surfaces.

Its non-toxic properties, moreover, are a massive plus, as chemicals in conventional sprays can distort DNA print analysis.

Jellyfish, of course, are leaving their own imprint in culinary circles
