Undergraduate research shows leaderless honeybee organizing

...education. Like human civilizations, bee societies follow organizational principles, such as following social rules (like human customs and laws) and division of labor. But here the similarity ends. Bees do not have large brains and are not capable of complex thought like humans. Though the bee colony is...

Ants show us how to make super-highways

"Broadly, our research demonstrates that a simple but highly specialised behaviour performed by a minority of ant workers can improve the performance of the majority, resulting in a clear benefit for the society ...

How brain pacemakers erase diseased messages

Thymus transplants gives hope to babies with fatal immune disease

...dren who received the transplant are alive, with a follow up of as long as 13 years. Markert said the 12 deaths occurred within one year of the transplant. The deaths were caused by various infections and were not a result of the surgery itself, she said. "These babies are very frail when they get her...

Danish researches solve virus puzzle

...instrument can grab the ends of the RNA tether and follow the process of how the pseudoknot is mechanically unfolded. A crucial slip of the cellular motor In their investigations the researchers use a pseudoknot which is related to bird flu. When the ribosome encounters a pseudoknot it has to unrave...

Studies force new view on biology of flavonoids

"We can now follow the activity of flavonoids in the body, and one thing that is clear is that the body sees them as foreign compounds and is trying to get rid of them," Frei said. "But this process of gearing up to get rid of unwanted compounds is inducing so-called P...

Mine runoff continues to provide clues to microbial diversification

"If we want to feed over nine billion people by the year 2050, then understanding the basic mechanics of plant growth is required," said Chory. "This knowledge will ultimately lead to our ability to increase yield, ...

When your brain talks, your muscles don't always listen
