Reversing pest resistance to biotech cotton: The secret is in the mix

A study published in the Proceedings of the National Academy of Sciences reveals that interbreeding genetically engineered cotton with non-Bt cotton can delay and even reverse evolution of resistance by pests. This novel strategy involves planting a mix of Bt and non-Bt seeds, which generates a random mixture of plants within fields.

Chronic administration of nandrolone decanoate

Chronic administration of nandrolone decanoate in albino mice increased serum aldosterone and sodium ion levels, indicating possible steroid-related cardiovascular disorders. The study suggests a correlation between altered aldosterone concentrations and cardiovascular diseases.

Threading the RSV vaccine needle

Researchers at Emory University School of Medicine have engineered a live attenuated RSV vaccine candidate that is highly effective in mice and cotton rats. The vaccine, called OE4, induces high levels of antibody production while maintaining its immunogenicity, making it a promising candidate for further clinical investigation.

Ancient wisdom boosts sustainability of biotech cotton

A new study suggests that biotechnology and traditional agriculture can be compatible approaches toward sustainable agriculture. Combining computer modeling and field research, the international team found that diverse patchwork of crops in northern China slowed adaptation to genetically engineered cotton by a wide-ranging insect pest.

Is self-fumigation for the birds?

Researchers discovered that finches in the Galapagos Islands use treated cotton to kill parasitic fly maggots, protecting baby birds and potentially helping endangered species. The biologists tested this self-fumigation method on Darwin's finches, showing that it is effective against the nest fly Philornis downsi.

Plant protein puzzle solved

Researchers from North Carolina State University have created a 3D model of an enzyme that links glucose to cellulose, a crucial component of plant cell walls. The breakthrough could enable genetic engineering of plants and trees for improved fibers or wood strength.

Multi-toxin biotech crops not silver bullets, scientists warn

A new study by University of Arizona entomologists reveals that the pyramid strategy for genetically modified crops may not be as durable as previously assumed. The research found that critical assumptions underlying the strategy do not always apply, and that some degree of cross-resistance between toxins can reduce its effectiveness.

Trouble on the horizon for GM crops?

A study by researchers at the University of Arizona found that pest populations are evolving resistance to genetically modified cotton plants, which produce toxins derived from Bacillus thuringiensis. The discovery highlights the need for closer monitoring and countering of pest resistance to biotech crops.

Baby wipes as safe as using water, study finds

A University of Manchester study found Johnson's Baby Extra Sensitive Wipes equivalent to water in hydrating newborn skin, challenging current NICE guidelines. The trial involved 280 babies and showed no significant differences in hydration or secondary outcomes, except for a slight increase in napkin dermatitis.
