Researchers Devise Easier and Cheaper Way to Produce Pheromones

Experts from Lund University developed a cheaper way of producing artificial pheromones that can confuse insects and prevent them to find mates. Manufacturing artificial pheromones is complex and expensive. It can cost around US$1,000 to US$3,500 per kilogram, and an additional US$40 to US$400 »

Weedy Rice has Become Herbicide Resistant through Rapid Evolution

In a paper published Sept. 8 in the journal Communications Biology, scientists from Washington University in St. Louis and the University of Arkansas report that a crop pest called weedy rice has become widely herbicide resistant in regions where herbicide-resistant rice is planted. The study highlights challenges facing U.S. »

Bigger Plants don't Always Equal More Nutritious Ones

While increased carbon dioxide levels in the atmosphere encourage plant growth, they also reduce the nutritional value of plants, which can have a larger impact on nutrition and food safety worldwide. Researchers at Michigan State University discovered a new way plants are adapting to the changing climate -- information that »

Cacao: Multiple Interactions in its Cultivation

It's not possible to grow cacao without insects -- that's logical. After all, they ensure that the flowers are pollinated and that the valuable cacao fruits, a sought-after material for the food industry, develop. Studies in Indonesia had shown in the past that birds and bats also contribute to increasing »

Apple’s Natural Defense against Virus Very Similar to GM Mechanism

Genetically modifying trees to increase resilience has long been hounded by regulatory hurdles and public opposition, but the latest findings of the University of Manchester's scientists offer an important contribution to this debate. The apple rubbery wood virus (ARWV) has infected many apple trees worldwide. In the study, the scientists »

Millions of Farmers 'Replumb' the World's Largest Delta

Collective groundwater pumping by millions of farmers in Bangladesh in the dry season each year has created vast natural reservoirs underground that, over a 30-year-period, rival the world's largest dams -- these sustain irrigation that has transformed this previously famine-prone country to a food-secure nation, according to a new study »

Multigene bioengineering increases yields in food crops

For the first time, RIPE researchers have proven that multigene bioengineering of photosynthesis increases the yield of a major food crop in field trials. After more than a decade of working toward this goal, a collaborative team led by the University of Illinois has transgenically altered soybean plants to increase »

Plasma-Produced Gas Helps Protect Plants from Pathogens

The flash of lightning and the dance of auroras contain a fourth state of matter known as plasma, which researchers have harnessed to produce a gas that may activate plant immunity against wide-spread diseases. The team, based at Tohoku University in Japan, published their findings recently in PLOS One. " »

Chinese Team Finds New Ways to Enhance Wheat Yield

Scientists from the Chinese Academy of Sciences and Peking University reported that gene editing of an APETALA2/ethylene responsive factor (AP2/ERF) transcription factor, DUO1, could lead to better wheat grain yield. Their findings are featured in Nature Plants. Wheat is one of the most important food crops worldwide. To »

AI Tool Predicts Shape of ~200 Million Proteins

Finding out the 3D structure of almost all protein will be as easy as googling. DeepMind, the Google-owned artificial intelligence (AI) company based in London, created AlphaFold, the revolutionary AI network that can predict the structures of over 200 million proteins of about 1 million species. “Essentially, you can think »
