Sunflower pollen protects bees from parasites
Solitary mason bees specializing on sunflower pollen were not attacked by a common brood-parasitic wasp, which lays eggs in the nests, where its larvae kill bee eggs and eat their pollen provisions. (2016-06-14)

Replacing soybean meal in pig diets
Canola, cottonseed, and sunflower products can replace soybean meal in diets fed to pigs, but they contain less protein and energy. To determine if it makes economic sense to use them, producers need to know the concentrations and digestibility of the nutrients they contain. To help them make the decision, University of Illinois researchers examined amino acid digestibility for these products. (2013-02-28)

Sea stars critical to kelp forest resilience
A study by Simon Fraser University resource and environmental management researcher Jenn Burt reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere. (2018-08-10)

Wildly stronger sunflowers
Annually, diseases, weeds, and insects are estimated to cause more than $1.3 billion in losses for sunflower growers. To combat this, researchers are preserving the genetic diversity of wild sunflowers. Wild plants retain the genes needed to resist pests and survive in different environments. (2017-03-15)

Oregano oil may help sunflower seeds keep longer
A study in the Journal of Food Science published by the Institute of Food Technologists showed that the addition of oregano essential oils to sunflower seeds preserved their positive sensory attributes and freshness quality. (2013-12-16)

Key sea star predator wiped out by disease and abnormally warm waters
From California to British Columbia, the abundance of sunflower starfish -- an important predator in the Northeast Pacific -- declined dramatically in both nearshore and deep waters from 2013 to 2015, according to a new study that leveraged citizen science diving surveys. This significant decline was due to the sea star wasting disease that ravaged the waters of the Northeast Pacific during this time. (2019-01-30)

Plant and animal breeders have long used hybridization to transfer useful traits between species. But does the same process happen without human aid? In a new study in the June issue of American Naturalist, researchers from Indiana University and Rice University explore how spontaneous hybridization - known as adaptive trait introgression - has a vital impact on adaptation and evolutionary diversification. (2006-05-10)

Survey shows impact of sea star wasting disease in Salish Sea
Sea star wasting disease has devastated intertidal populations of these animals on the West coast from Mexico to Alaska. But what about sea stars that live below the low tide line, mostly out of sight? An analysis of data collected by divers in the Salish Sea shows severe impacts on some species, especially the sunflower sea star, Pycnopodia helianthoides. (2016-10-26)

Sunflower oil shows unexpected efficiency in corrosion prevention
Sunflower oil, which is found in almost every home, can be used not only in cooking, everyday life and cosmetology - it will help avoid complications (gas hydrates and corrosion) during oil and gas production. Scientists of the priority area of Kazan University intend to apply inhibitors developed on its basis in harsh Arctic conditions. (2020-08-28)

Bees' medicine chest should include sunflower pollen, UMass Amherst study suggests
A new study by Jonathan Giacomini and his former advisor, evolutionary ecologist Lynn Adler at the University of Massachusetts Amherst, with others, found that eating sunflower pollen dramatically and consistently reduced a protozoan pathogen infection in bumble bees and reduced a microsporidian pathogen of the European honey bee, raising the possibility that sunflowers may provide a simple solution to improve the health of economically and ecologically important pollinators. (2018-09-26)

Wild bees make honeybees better pollinators
Up to a third of our food supply depends on pollination by domesticated honeybees, but the insects are up to five times more efficient when wild bees buzz the same fields. (2006-09-21)

Poly/mono balance important to cholesterol-lowering diet
In the search for the best fats for a heart healthy diet, trans- and saturated fats have long been recognized as undesirable and those that contain polyunsaturated fatty acids (PUFAs) and mono-unsaturated fatty acids (MUFAs) are preferred -- with no clear benefit demonstrated for higher levels of either the PUFAs or the MUFAs within recommended limits. (2005-07-01)

Student study bolsters case for adding a rare sunflower to the endangered species list
A native species of sunflower, called the giant whorled sunflower, is only known to exist in four locations in the Southeast United States. In the last four years, Vanderbilt graduate student Jennifer Ellis has conducted a series of genetic studies that significantly increase the odds that this gangly plant will be placed on the endangered species list.

Ancient sunflower fuels debate about agriculture in the Americas
Lentz and his fellow researchers have documented archaeological, linguistic, ethnographic and ethnohistoric data demonstrating that the sunflower had entered the repertoire of Mexican domesticates by 2600 B.C., that its cultivation was widespread in Mexico and extended as far south as El Salvador by the first millennium B.C., that it was well known to the Aztecs, and that it is still in use by traditional Mesoamerican cultures today. (2008-04-29)

The anatomy of petal drop in sunflowers
Anatomical analysis of two sunflower cultivars revealed a differentiated region at the junction of the flowers' petal and achene. Cell division at the abscission zone of the short-lived cultivar occurred earlier than in the long-lived cultivar, indicating that the tempo of development differed; the abscission layer reached full maturity sooner in Procut Bicolor, resulting in earlier petal drop, than in Procut Yellow Lite. Vase life was also correlated to flower color. (2015-01-14)

A new study by Simon Fraser University marine ecologists has discovered that a mass mortality of sea stars resulted in a domino effect on the B.C. West Coast's Howe Sound marine ecology. In the summer of 2013, millions of sea stars along the West Coast contracted a wasting disease and died in one of the largest wildlife mass mortality events ever recorded. (2016-06-23)

Sunflowers move from east to west, and back, by the clock
At the nearby University of California, Davis, plant biologists have now discovered how sunflowers use their internal circadian 'clocks,' acting on growth hormones, to follow the sun during the day as they grow. (2016-08-25)

Researchers from the University of the Basque Country have been the first to discover the presence of certain aldehydes in food, which are believed to be related to some neurodegenerative diseases and some types of cancer. These toxic compounds can be found in some oils, such as sunflower oil, when heated at a suitable temperature for frying. (2012-02-22)

Vitamin E in canola and other oils hurts lungs
A large new study upends our understanding of vitamin E and ties increasing consumption of supposedly healthy, vitamin E-rich oils -- canola, soybean and corn -- to the rising incidence of lung inflammation and, possibly, asthma. The good news: vitamin E in olive and sunflower oils improves lungs. The study shows drastically different health effects of vitamin E depending on its form: gamma-tocopherol in soybean, canola and corn oil and alpha-tocopherol in olive and sunflower oils. (2014-05-20)

Neiker-Tecnalia study use of oilseedrape and sunflower oils to produce fuel and feed for herds
The oil extracted from oleaginous plants can be used as a fuel for agricultural vehicles without any reduction in their performance -- thus enabling farmers to have greater energy self-sufficiency. Besides this, a sub-product known as oilseedcake is extracted, and which is optimum fodder for animal herds, given its significant protein and fatty acids content. (2010-07-23)
