Os organismos vivos, quando submetidos à pressão de seleção natural ou artificial, apresentam alta capacidade de evoluir, atributo este que vêm sendo explorado com a finalidade de melhorar a capacidade produtiva e reprodutiva das espécies domesticadas. Os métodos convencionais (genética quantitativa e de populações) envolvidos no processo de melhoramento genético não têm, necessariamente, como base o conhecimento do gene e (ou) seu mecanismo de funcionamento envolvido na expressão da característica de interesse, portanto, pode resultar no favorecimento da expressão de genes com efeito secundários, que podem ter efeitos negativos para o setor produtivo, para o consumidor ou para o meio ambiente.

Science – When Ralf Reski read the latest paper from controversial French biologist Gilles-Eric Séralini, he quickly decided he wanted nothing to do with it. Séralini’s report in BioMed Research International describes how pesticides kill cultured human cells, with the hair-raising conclusion that pesticides may be vastly more toxic than assumed by regulatory authorities. Some scientists are criticizing the findings as neither surprising nor significant—but they have touched off a firestorm, with environmental groups calling for changes in how pesticides are regulated. That was too much for Reski. Within hours of reading the paper last week, the plant scientist at the University of Freiburg in Germany resigned as an editor of the journal and asked for his name to be removed from its website. “I do not want to be connected to a journal that provides [Séralini] a forum for such kind of agitation,” he wrote in his resignation e-mail to the publisher, Hindawi Publishing Corporation.
CHANGSHA – A 59-year-old man having close contact with live poultry died on Monday morning of the H7N9 flu virus, the first of its kind in central China’s Hunan province, local authority said.
A separate statement issued by the health department of Guangdong province on Monday said a patient surnamed Xie died of the virus on Sunday in Foshan after treatment failed.
With the new cases, H7N9 has so far killed 25 people in China since January, and the number of human infections has been 113, with Zhejiang and Guangdong being mostly affected.
The Pig Site – Funded through the bilateral agreement for implementation of Growing Forward 2, this programme will help businesses comply with the requirements relating to the restraining of animals during slaughter, in order to eliminate the suffering of these animals while taking into consideration the concerns of Canadians regarding animal welfare.
The programme will be allocated a budget of C$450,000 spread over three years, from 2013 to 2016.
“Canada has a strong record supporting the use of best practices in the slaughter industry. We are pleased to partner with Quebec to further promote the development of practices that take animal welfare into account,” said Federal Agriculture and Agri-Food Minister Gerry Ritz

Agência FAPESP – Stingless bees, such as the jataí (Tetragonisca angustula) and the uruçu (Melipona scutellaris), are well known as important pollinators for several crops such as eggplant, strawberries, tomato and coffee.
One of the main limitations on their use for this purpose, however, is the difficulty of producing colonies in sufficient quantities to meet the demands of farmers, as the majority of these species have small numbers of queens.
However, a new technique that could help overcome this limitation was developed by a group of researchers who reared the queens of one of these species in vitro: Scaptotrigona depilis, commonly known in Brazil as mandaguari…>>Continue Reading<<

The Pig Site – The EU meat sector is expected to be supported by strong demand on the world market driven by favourable economic conditions. In Europe, prospects of improved economic growth should leave consumers with more disposable income allowing for a higher consumption of meat products.

Agência FAPESP – In addition to producing food, services and energy, agricultural pastures have a secondary but equally important role, a role that should be strengthened: the conservation of biological diversity.
Professor Luciano Martins Verdade, of the Center for Nuclear Energy in Agriculture at Universidade de São Paulo (CENA/USP), discussed this topic during the last meeting of the 2013 BIOTA-FAPESP Education Conference Cycle, organized by the FAPESP Research Program for the Characterization, Conservation and Sustainable Use of Biodiversity (BIOTA-FAPESP). Held on November 21, 2013 at FAPESP’s headquarters, the theme was “Biodiversity in Urban and Rural Anthropic Environments.” >>Continue Reading<<
