Satellite-based Control of Fishing

Russia incurs significant losses as a result of breaking fishing rules. Satellite-based control over domestic and foreign illegal fishers is most efficient. Watching the industrial fishing vessels by satellite is already practiced in Kamchatka.

Joint effort of the State Committee for Fisheries of the Russian Federation, Basin Administration for Fish Conservation of the Federal State Office “Sevvostryvod”, and Kamchatka Centre of Communication and Monitoring (KCCM) has allowed for testing the

Signal chemical primes plants for pest attack

Physically damaged or chewed plants produce a volatile chemical that may serve as a primer to prepare nearby plants to defend themselves against insect attack, according to a team of researchers.

“We know that when caterpillars chew on plants, eventually the plants produce chemicals attracting wasps that are the natural enemy of the caterpillar,” says Dr. James H. Tumlinson, the Ralph O. Mumma endowed professor of entomology at Penn State. “Natural predators can be an effective method of bi

Herbal alternative to farmyard antibiotics

Research at the University of Leeds into herbal remedies in the farmyard could soon see pigswill garnished with garlic and cows chewing on cinnamon-flavoured cud. With an EU ban on antibiotic growth promoters in animal feed from 2006, alternatives need to be found urgently. The use of plant extracts, once dismissed as quack science, is attracting growing interest from the industry.

Dr Henry Greathead, researcher at the department of biology, is experimenting with essential oils from thyme as

Development of new food additives extracted from the solid residue of tomatoes

In Europe, 8.5 million tons of tomatoes are cultivated annually. 1.5 million tons are sold directly to the consumer and 7 million are processed for products such as ketchup, sauces, etc. During this processing, some 40% of the tomato raw material ends up as residue mainly skin and seeds. The seeds, considered by the processing industry simply as waste or used as animal feed, is still an excellent source of nutrients such as carotenoids, proteins, sugars, fibre, wax and oils, these oils being nutritio

New effects of herbicides on plants

The aim of Navarre engineer Ana Zabalza Aznárez’s PhD thesis – entitled “The inhibition of the biosynthesis of amino acids in ramified chain and their use as a target-site for herbicides” – was to find out what effects herbicides produce on the metabolism of plants so as to enable a more rational use of them.

According to lecturer Zabalza Aznárez, herbicides have undergone considerable development since they began to be developed in the fifties of the last century in order to eliminate wee

NASA satellites improve response to global agricultural change

NASA’s Earth satellite observing systems are helping the U.S. Department of Agriculture Foreign Agricultural Service (FAS) improve the accuracy and timeliness of information they provide about important crops around the world. FAS information is crucial in decisions affecting U.S. agriculture, trade policy, and food aid.

NASA and the University of Maryland are providing the FAS with observations and data products from instruments on NASA’s Aqua and Terra satellites and from the TO
