Russian scientists have analgesic from the venom of the spider

Scientists from the Institute of Bioorganic Chemistry. MM Shemyakin Ovchinnikov Institute opened in the venom of the wolf spider substance that serves as a potent analgesic than morphine and is not addictive. Now it takes place pre-clinical trials.

Pain — the main reason why people go to the doctor. This kind of signal: if it hurts, it means that something is wrong and we must take action. But there are pathological persistent pain that signal the most dysfunctional neuronal systems and the transfer of the pain signal. Such, for example, phantom pain — the pain is nothing, but still hurts.

Mice have a strange food to other mice

Despite the lack of speech abilities, animals still communicate. No language or gestures, but they give each other aware of the danger, sexual arousal or aggressive mood. Most communication between animals occurs at the level of the olfactory — they "talk" to their noses and secretory glands.

Animals, including mammals, unwittingly, give their aggressive mood and sexual arousal aromatic chemicals — pheromones. Pheromones also convey information about health, genetic usefulness and hierarchical status animal. Infox.ru wrote about how termites inhibit sexual activity in genetically abnormal females. In general, the molecular, cellular and neural mechanisms of communication in the language of

Do fish feel pain?

10.07.2013

 

Although this question is as old as fishing itself, but clearly it still has not been answered. In a recent study, researchers concluded that the brain of fish is not enough pain receptors necessary to feel pain as humans or animals.

Some scholars argue that the pain receptors of fish that respond to physical damage, operate at the level of reflexes, but do not transmit pain.

"Even if the fish had a mind to suggest that they are
