Après 40 % de baisse en dix ans, les progrès dans l’exposition des animaux d’élevage marquent le pas. Des mesures sur la densité des élevages, l’espace accordé aux animaux et la qualité du transport permettent de freiner la propagation des maladies et, donc, les antibiotiques. 163290848/Davy3 Photo – stock.adobe.com En quelques années à peine, le monde…

Poings serrés, Aurore dort paisiblement. La petite fille vient de naître, et ses parents attendris ne voient pas les mauvaises fées qui se penchent sur l’enfant endormie. Elles ont pour nom malnutrition, diarrhée, pollution et sécheresse, et elles accompagneront Aurore tout au long de son existence. Les adultes savent bien qu’elles approchent, qu’elles sont déjà…

10 % des matières plastiques qui polluent les mers sont originaires de la pêche. Les filets abandonnés tuent annuellement 100.000 baleines, dauphins, otaries, phoques et autres tortues, estime l’ONG World Animal Protection. 191131771/Richard Carey – stock.adobe.com Après l’agriculture et ses intrants polluants, c’est au tour de l’industrie de la pêche de subir les foudres des ONG.…

[Fonte: GLP] Micro-organisms living inside plant roots team up to boost the plant’s growth and tolerance to stress. An international research team led by the Netherlands Institute of Ecology (NIOO-KNAW) and Wageningen UR reports its discovery in …. the scientific journal Science. Certain species of ‘resident’ bacteria can protect plant roots against fungal infections. Researchers from…

[Fonte: Embrapa] Projeções recentes do Ministério da Agricultura, Pecuária e Abastecimento indicam que a produção brasileira de grãos passará dos atuais 236 para 300 milhões de toneladas e a de carnes de 26 para 33 milhões de toneladas em 2028/2029. Significam um acréscimo de quase 30% no período. Também é crescente a produção de celulose,…

[Fonte: GLP] Approximately one person in 100 has celiac disease, which means for them eating gluten is risking diarrhea, vomiting, malnutrition, and even brain damage and gut cancer. Add to this group those who are gluten sensitive and you get 7% of the population avoiding foods that contain gluten. It is the class of gliadin…

[Fonte: CSHL] Plant scientists at Cold Spring Harbor Laboratory (CSHL) and USDA’s Agricultural Research Service (ARS), in their search for solutions to global food production challenges, have doubled the amount of grains that a sorghum plant can yield. Sorghum, one of the world’s most important sources of food, animal feed, and biofuel, is considered a…

[Fonte: GLP] Introducing fungi to wheat boosted their uptake of key nutrients and could lead to new, ‘climate smart’ varieties of crops, according to a new study. Researchers at the University of Leeds have demonstrated a partnership between wheat and soil fungi that could be utilized to develop new food crops and farming systems which…

[Fonte: ANU] Australian research could help breeders develop more drought-resilient crops that can produce more food and more profit with less water. Our work may be instrumental for farmers to maximise food production in the face of increasingly severe drought. Drought tolerance is critically important in the face of climate change, population growth and land-use…

[Fonte: GLP] A team of scientists from the United States announced that they have identified the protein in plants responsible for its cellular defense against excessive light, among other stress factors caused by climate change. Published literature states that photosynthesis occurs in the plant cell’s chloroplast. In these chloroplasts, proteins make up the molecular structure that is responsible…

[Fonte: Embrapa] Avaliar a utilização de agrotóxicos e sua compatibilidade com agentes de controle biológico (parasitoides) contra a traça-do-tomateiro é o principal objetivo dos experimentos que vêm sendo conduzidos desde 2018 na Embrapa Hortaliças (Brasília-DF), com resultados que têm permitido confirmar a eficácia dos métodos utilizados. “Em função do que tem sido observado até agora, as respostas…

Une large analyse montre que les services apportés par la nature, comme la pollinisation, profitent à la plupart des cultures agricoles, en l’absence de pesticides.

Finalement, les premiers résultats sur la qualité du lait sont «rassurants», comme l’indiquait, vendredi 11 octobre, à Rouen (Seine-Maritime), Roger Genet, le directeur général de l’Anses (Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail). Il avait fait cette déclaration à l’occasion de l’installation du «comité pour la transparence et le dialogue»…

Des chercheurs japonais ont peint des bovins pour que leurs robes imitent celles des zèbres. Ils attirent ainsi deux fois moins d’insectes. Des chercheurs japonais ont orné de rayures blanches six vaches noires pour vérifier si la stratégie chasse-mouches des zèbres fonctionnait avec une autre espèce.

[Fonte: GLP] Studies conducted at the Australian Plant Phenomics Facility (APPF) showed experimental genetically modified (GM) wheat lines [have] the potential to significantly increase yields. These lines ‘overexpress’ three wild-type plant genes, either individually or in combination, and were developed to test whether targeting individual wheat genes could lead to improvements in yield. In greenhouse studies conducted at the…

[Fonte: GLP] For the past two years, researchers at the University of California, Davis, have been studying six offspring of a dairy bull, genome-edited to prevent it from growing horns. This technology has been proposed as an alternative to dehorning, a common management practice performed to protect other cattle and human handlers from injuries. UC…

[Fonte: GLP] Above a Saskatchewan field, a line of drones rises in formation, sensors primed to pick out enemy targets below. But this isn’t the latest Terminator movie. This is Daniel McCann’s brainchild for green-on-green spot spraying, an offshoot of precision spraying that promises to identify and take out weeds in a growing crop. Why…

[Fonte: GLP] Genome editing could be a ‘key tool’ in improving the efficiency of UK pig production and could help in tackling devastating diseases such as African swine fever. … In 2017, scientists used the method to create male pigs that could be used as surrogates capable of producing sperm that contains the genetic blueprint of sought-after…
