Why food sticks to nonstick frying pans
Foods will sometimes get stuck to a heated surface, even if oil or a nonstick frying pan is used. Scientists have investigated the fluid properties of oil on a flat surface and their work shows convection may be to blame. When the pan is heated from below, a temperature gradient is established in the oil film, as well as a surface tension gradient. This gradient sets up a type of convection known as thermocapillary convection. (2021-02-02)

Fatty acid may help combat multiple sclerosis
The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study. The finding suggests that dietary change might help treat some people with the autoimmune disease. (2021-01-19)

A RUDN University biologist described how a harmless bacterium turns into a phytopathogen
A researcher from RUDN University suggested that Xanthomonas bacteria that are harmful to plants might have developed from a nonpathogenic related species by receiving virulence genes from other species of bacteria. (2020-10-03)

Sky islands and tropical alpine sunflowers at risk of disappearing
The plants that live among the mountaintops of the Andes are among those most threatened by climate change because these species have no place left to go to escape rising temperatures. A recent study predicts how well a tropical alpine plant---relatives of sunflowers in the genus Espeletia--might adapt to both climate change and other human activities such as agriculture, mining and rising human populations.

Scientists "scent train" honeybees to boost sunflowers' seed production
If you want a dog to hunt something down, it helps to let them sniff an item to pick up the scent. Now, researchers reporting in Current Biology on September 17 have found that scent training honeybees might work in a similar way--and that this approach could make bees more efficient in pollinating crops. The findings show that honeybees given food scented with sunflower odors led to a significant increase in sunflower crop production. (2020-09-17)

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)

Easy to overdose on paracetamol if you're selenium deficient, says research

How listening to music 'significantly impairs' creativity
The popular view that music enhances creativity has been challenged by researchers who say it has the opposite effect. Psychologists investigated the impact of background music on performance by presenting people with verbal insight problems that are believed to tap creativity. They found that background music 'significantly impaired' people's ability to complete tasks testing verbal creativity -- but there was no effect for background library noise. (2019-02-27)

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)

Health risks through fumigated containers
Products transported by sea in containers are often fumigated with biocides as protection against pests. In addition to this, they often contain volatile organic solvents, such as the potentially carcinogenic 1,2-dichloroethane, which can originate from cleaning or manufacturing processes. In a meeting held at the German Federal Institute for Risk Assessment (BfR) on 16 November 2018, 36 experts from science, monitoring authorities, trade and industry discussed the effects of substances of this kind on health, along with the need for future action. (2019-01-16)

Effects of linoleic acid on inflammatory response depend on genes
The effects of linoleic acid on the human body are largely dependent on genes, a new study from the University of Eastern Finland shows. Linoleic acid is an essential fatty acid. People carrying different variants of the FADS1 gene had a different inflammatory response and different changes in their fasting glucose levels when supplementing their diet by linoleic acid rich sunflower oil. This was the first time these associations were studied in humans. (2019-01-15)
