In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the ‘80s in the UK. Their market is yearly increasing with 25% in West Europe.
Packaging fresh-cut vegetables under an Equilibrium Modified Atmosphere (EMA) is one of the new applied food packaging technologies offering a prolonged shelf-life of re
Footprints and a fire found from 20,000 years ago.
Handprints and footprints 20,000 years old reveal that people lived on the Tibetan plateau at the height of the Ice Age – 16,000 years earlier than scientists had thought. The newly found signs of life cast doubt on the idea that a glacier a kilometre thick covered the plateau at that time.
David Zhang and S. H. Li of the University of Hong Kong found the marks of at least six individuals, including two children, in marble-l
Biotech bugs turn indigo blue in a green way.
Jeans dyed blue by bacteria may soon be swaggering down the streets. Researchers have genetically modified bugs to churn out the indigo pigment used to stain denim. The process could be a greener rival to chemical indigo production.
Originally extracted from plants, indigo dye is now made from coal or oil, with potentially toxic by-products. Bacteria have previously been adapted as alternative indigo manufacturers, but a trace by-
Astronomers shoot first film of the stars, dust and gas at the centre of a galaxy.
Astronomers have made their first movie of the roiling mass of stars, dust and gas at the centre of a galaxy.
The movie zooms into the disk of saucer-shaped galaxy NGC 1068 and through its super-bright core. It reveals an energetic region of space created by material flying out of the suspected black hole at the centre and crashing back into the disk. This region appears as a pale blue cloud
The hydrological regime of the inner delta of the River Niger, situated in Mali, is subject to strong annual and indeed intra-annual variability. This delta ecosystem has a characteristic feature, a three-phase cycle. The first, a period of flood, starts in July marking the beginning of the cycle; then, after several months of rising water-levels, the flood recedes, between November and January; finally, a period of low water prevails between March and June.

An extremely intense El Niño event in 1983 prompted an international surveillance programme, involving the deployment of moored or drift measurement buoys and observation satellites. This research effort is proving to be fruitful. The data obtained provide a key to understanding how the two components of the now-famous two-phase system El Niño Southern Oscillation (ENSO) -El Niño and its reverse counterpart La Niña- are generated. Forecasting models for three months in advance are quite reliable. How
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
