Undergraduate research shows leaderless honeybee organizing

...heir wing muscles rapidly, appears to be a general instruction to fly. The researchers document that the workers stop using the vibration signal when the queen flies and leaves the nest with the swarm. Piping, however, continues in the swarm, as the bees need to make the queen fly again once a new nest site h...

New findings challenge established views on human genome

... sequence is similar to having all the pages of an instruction manual needed to make the human body. Researchers still must learn how to read the manual’s language so they can identify every part and understand how the parts work together to contribute to health and disease. In recent years, researchers have...

Instruction manual for creating a molecular nose

...o the receptors. "We now have something akin to an instruction manual on how membrane proteins that were previously difficult to access can be produced and analyzed in their active structure," says Sinner. The new procedure developed by Eva-Kathrin Sinner and her research group makes it possible, for the fir...

Molecular 'signature' protects cells from viruses

...nstantly produces a whole arsenal of proteins. The instruction what is to be built comes from the cell nucleus: this is where the DNA is stored, the heredity molecule in which, so to speak, the construction blueprints for all cellular proteins are stored. If a particular protein is to be produced, the appropriat...

Chimpanzees can transmit cultural behavior to multiple 'generations'

...lowed to explore the testing box but were given no instruction or training to open the testing box. Once each individual animal from the first two social groups proved successful, another animal from the same social group was allowed to observe the process before interacting with the testing box. Once the second...

Obese people are more sensitive to pain, suggests study

...rned different ways of coping with pain, including instruction in progressive muscle relaxation therapy. The electrical stimulation came from an iPod-sized device that delivered a slight electrical shock to a patient's sural nerve, a nerve that extends along the ankle and into the calf. This kind of electrical ...

Birds that make teeth

...irds retain the ability to make teeth even without instruction from their tooth-bearing cousins. In the new work, the researchers show that the talpid2 strain of chicken harbors a genetic change that permits tooth formation in both the upper and lower jaw of embryonic birds. These teeth show similar developmen...

Fragment of yellow fever virus may hold key to safer vaccine

...r vaccines must contain this essential fragment of instruction to the immune system, said ter Meulen, senior author of a study published in the July 5, 2005, issue of the journal Virology and published early online. These days, the horror of Ebola or Marburg hemorrhagic fever grabs more attention, but yellow fe...
