Evolution has enabled plants to survive under adverse conditions. The winter bud of a plant is a crucial structure that establishes adaptability. Depending on environmental and intrinsic conditions, buds can transition between growth and dormancy. The three dormancy phases are determined by signals triggering each phase: ecodormancy, influenced by environmental factors; paradormancy, promoted by other plant organs; and endodormancy, maintained by internal signals within the bud. Paradormant buds enter endodormancy in response to changes in day length and/or low temperature in autumn, while endo-and eco-dormant phases occur ...
Scientists on the team of Dr Lenka Maletínská have developed a promising new compound derived from one of the peptides naturally occurring in the brain. Its application may contribute to the addressing of two major health challenges of the modern days: obesity and Alzheimer's disease. The neuropeptide CART is primarily associated with the regulation of food intake. Its modified version, created at the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences, shows better stability and is more effective. It suppresses appetite and protects the brain by reducing the pathogenicity of the tau protein, which is associated with ...
The innovative strength of a society depends on the level of academic freedom. An international team involving the Technical University of Munich (TUM) has now proven this relationship for the first time. The researchers analyzed patent applications and patent citations in a sample from around 160 countries over the 1900–2015 period in relation to indicators used in the Academic Freedom Index. In view of the global decline in academic freedom over the past 10 years, the researchers predict a loss ...
SPOKANE, Wash. – Just the facts may not be enough to overcome misinformation, a recent study indicates.
In an experiment, 152 college students who had been exposed to misinformation read one of two articles intended to give them the correct, scientifically backed information. Those who read an expository article that had “just the facts” retained more misconceptions than those who read an article with a refutation—meaning it specifically called out the false claims before presenting the facts.
The ...
DENVER, Aug. 21, 2024 — In the scorching heat of summer, anyone who spends time outside — athletes, landscapers, kids at the park or beachgoers — could benefit from a cooling fabric. While there are some textiles that reflect the sun’s rays or transfer heat away from the body, current options require boutique fibers or complex manufacturing processes. But now, researchers report a durable chalk-based coating that cools the air underneath treated fabric by up to 8 degrees Fahrenheit.

DENVER, Aug. 21, 2024 — Tortilla chips and fresh salsa are tasty in themselves, but they could be even more appealing if you grow the ingredients in a sustainable way. Researchers report that cilantro, bell pepper and jalapeño can be cultivated in recycled glass from discarded, pulverized bottles like those from beer or soda. The pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.
The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 is ...
The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these formulas don’t work in every situation. To compensate, they have added ad hoc “correction factors” based on empirical observations.
Now, for the first time, engineers at MIT have developed a comprehensive, physics-based model that accurately represents the airflow around rotors even under extreme conditions, such as when the blades are operating at high forces and speeds, or are angled in certain directions. The model could improve the way rotors themselves ...
