Many farmers struggle with an enemy that looks like a friend. Agricultural weeds that are close relatives of crops present a particular challenge to farmers because their physical similarities to the desirable species make them difficult to detect and eradicate. Along the way, the imitators compete with crops for water, nutrients and space — often depressing crop yields.
Alfred Ozimati is breeding the latest in disease-resistant cassava that meets the needs of subsistence farmers, thanks to the NextGen Cassava project run by Cornell University.

Technology lends a hand during tedious seed counting process
Australia's first plant foods - eaten by early populations 65,000 years ago - have been discovered in Arnhem Land.
The study looked at areas in the Brazilian Amazon with varying levels of disturbance from activities like logging or burning.
Cornell University researchers analyzed farmer preferences and found that the softness of cooked cassava is a major influence on what kinds of varieties farmers actually adopt.
A Cornell University researcher has developed a new, flavorful and highly productive cherry tomato – that ripens green. The new variety, dubbed Jaded, was created by Phillip Griffiths, associate professor of horticulture at Cornell Agritech, who bred it from four heirloom tomato varieties.
The researchers examined satellite imagery, air temperature data and phenology (plant life cycle) models for 85 large cities and their surrounding rural areas from 2001 through 2014 to better understand changes in tree leaf emergence, also called budburst, on a broad scale across the United States. The study can help scientists improve their modeling of the potential impacts of future warming.
Satellite data of 85 U.S. cities shows plants begin turning green earlier in the spring in urban areas than in surrounding rural areas. It’s a symptom of the way cities trap heat, a phenomenon known as the “heat-island effect,” according to a recently published study.
Some of the antibiotics we use end up in sewage sludge, together with a variety of antibiotic resistant bacteria present in feces.
The Woodroofs developed methods still used today to grow, harvest and store crops. Also pioneers in their own right, they faced Depression-era economic difficulties, and later traveled to underdeveloped countries around the world to teach others how to process and preserve food.
A Lawrence Livermore National Laboratory scientist and international collaborators have developed a framework for testing nutrient limitations and a benchmark of nitrogen and phosphorus limitation for models to be used for predictions of the terrestrial carbon sink.
Five years ago, onion growers in New York state started reporting large incidents of premature leaf death in their fields. It affected nearly 75% of growers’ crops and put a dent in the state’s onion industry, which has a four-year average value of $44.7 million, based on data from the U.S. Department of Agriculture. Researchers identified the culprit as Stemphylium leaf blight (SLB), a relatively new and increasingly devastating disease. In a recent study, researchers at Cornell AgriTech have identified better ways to manage SLB and use fungicide more effectively.
In a UCLA-led phase I clinical trial, a new plant-based drug called APG-157 showed signs of helping patients fight oral and oropharyngeal cancers. These cancers are located in the head and the neck. APG-157 is made up of multiple compounds produced by plants, including curcumin. UCLA Jonsson Comprehensive Cancer Center researchers found that treatment with this botanical drug resulted in high concentrations of curcumin and its byproducts circulating in the blood and absorbed by tumor tissues within three hours after being taken orally.
Using an innovative genome sequencing technology, researchers assembled the complete genetic blueprint of two basmati rice varieties, including one that is drought-tolerant and resistant to bacterial disease. The findings, published in Genome Biology, also show that basmati rice is a hybrid of two other rice groups.
Study shows improvement of soils and streams in the southern Appalachians
Scientists solved a critical part of the mystery of photosynthesis, focusing on the initial, ultrafast events through which photosynthetic proteins capture light and use it to initiate a series of electron transfer reactions.
A recent study by the University of Kent has called for an increase in scientific surveys and collection of specimens to confirm the extinction of ultra-rare species.
The profound threat of future climate change to biodiversity demands that scientists seek ever more effective ways to identify the most vulnerable species, communities, and ecosystems. In a new study, published in Nature Climate Change, an international team of scientists has shown that the most biodiverse regions on Earth are among the most vulnerable to future climate change.
Drifting algae in the Austral Ocean can bring invasive species to the Antarctic coasts, according to a study published in the journal Scientific Reports.
Soil scientists from Cornell and Rice Universities have dug around and found that although adding carbon organic matter to agricultural fields is usually advantageous, it may muddle the beneficial underground communication between legume plants and microorganisms.
Trees are known for their great, but not unlimited, trunk height and diameter.
As the hemp industry grows, producers face the risk of cultivating a crop that can become unusable – and illegal – if it develops too much of the psychoactive chemical THC. Cornell University researchers have determined that a hemp plant’s propensity to ‘go hot’ – become too high in THC – is determined by genetics, not as a stress response to growing conditions, contrary to popular belief.
Nearly everyone on Earth is familiar with corn. Literally. Around the world, each person eats an average of 70 pounds of the grain each year, with even more grown for animal feed and biofuel.
The production of formate from CO2 is considered an attractive strategy for the long-term storage of solar renewable energy in chemical form.
