Vineyards across the U.S. and Italy are being devastated by incurable diseases caused by bacteria hitching a ride on leafhoppers — a diverse group of plant-piercing insects closely related to cicadas. Now, thanks to some innovative research, scientists are using a technique called vibrational mating disruption to interrupt male-leafhopper courtship songs, preventing them from finding mates and slowing population growth.
Alison Van Eenennaam, an extension specialist at UC Davis working in beef genomics surveys the data and evidence relating to concerns about the use of medically important antibiotics in livestock production.
Three examples of genetic engineering of crops show that extremely modest engineered changes in plant genetics can result in very important benefits. These three examples involve engineered changes that trigger the natural defenses of the plant without introducing novel defense mechanisms.
Agronomist Andrew McGuire explains why there is not enough manure or compost available – and can never be enough – to replenish soil fertility at a systems level. Studies that show improved outcomes on single farms are not measuring improvement at a systems level.
Returning manure to the soil that produced it can be a sustainable way of restoring soil organic matter. Too often the organic matter of many farms is pushed through the bottleneck of intensive livestock production to be applied just a few farms. Robbing Peter to pay Paul.
Can we produce enough manure to serve as a major source of soil nutrients? Agronomist Andrew McGuire shows the limitations due to entropy make it impossible for manure to make up more than a portion of nutrient replenishment.
Looking for a New Year’s resolution that won’t trigger any guilt when you fail? Take a little time and read up on the latest research in plant breeding every now and then.
A recent documentary on RoundUp on Norwegian state television went dumpster diving for some of the most discredited ideas about the popular herbicide.
Kevin Folta of the University of Florida explains why molecular biologists and plant breeders must play a role in Climate Smart Agriculture.
Breeding nitrogen-efficient plants could boost crop productivity and dramatically reduce greenhouse gas emissions while reducing fertilizer use.
Professor Kevin Folta challenges the Berkeley 45 to publicly engage on their claims that the documentary Food Evolution is a propaganda film. They refused.
The Science Moms wade into the controversy over “ Food Evolution ” a new documentary about GMOs that anti-GMO activists are calling propaganda.
Reporting on two new papers on neocotinoids and bee health single out the pesticides, but a closer look at the data doesn’t support that angle.
Kevin Folta explains why it’s important to use the scientifically accurate term “genetically engineered” to refer to biotech crops and animals rather than the sloppy and baggage laden “GMO”.
Five years ago, Kulsom and his colleague Lisette Kreischer founded a company called The Dutch Weed Burger after they shot a documentary about the role of seaweed as a future source of protein. Kulsom says the company’s mission is “to work on the acceptance of seaweed becoming a part of the new paradigm.”
Enter their first product: the weed burger.
At first, a seaweed burger seems like an unusual choice, but it begins to make sense after a while.
In the last decade or so, vast amounts of money have been invested in the development of algae for biofuel production. This made sense because, ten years ago, there was a need to find alternatives to fossil fuels due to the high oil price and the increasing recognition that carbon emissions were causing climate change. Algal biofuels were touted as the answer to these twin problems, and huge investment followed.
Unfortunately, things didn’t go quite to plan.
When a research team included an industry partner, our participants were generally less likely to think the scientists would consider a full range of evidence and listen to different voices. An industry partner also reduced how much participants believed any resulting data would provide meaningful guidance for making decisions.
How can you tell good science from bad science? As the quality of peer review falters and pop science reporting relies on controversy it gets harder all the time. Here are six guidelines for separating the signal from the noise.
Colin K. Khoury of the International Center for Tropical Agriculture looks at claims that 75% of crop diversity has been lost in the modern era. Instead, he finds that though there have been winners and losers among crops as agriculture has intensified, over the past 50 years, almost all countries’ diets actually became more diverse, not less, for the crops that FAO statistics do report.
Agronomist Andrew McGuire looks at too opposite problems in managing soil and then lays out a few principles for staying away from two extremes.
