The flowers have pollen under control
Biologists have found that the ovary of the flower is strictly controls the germination of pollen pollinate it - immediately after fertilization, it is not available for all latecomers dust. But if fertilization of the egg for some reason did not happen, "Race dust" begins again.

Plutonium surrendered magnetic resonance
Physicists first time succeeded in nuclear magnetic resonance parameters for plutonium. He was the last element for which these parameters remained unknown. The new findings will help in studying the chemical properties of the compounds of this element and, consequently, will clarify the processes of nuclear waste.

"Kepler" evaporating exoplanet discovered
Astronomers have discovered exoplanet, which may not be just over 100 million years. Its substance is rapidly evaporated under the action of light is located close to the star and forms a cosmic cloud. According to the authors, this can happen by throwing the ashes of volcanoes, or by evaporation of metals.

A pair of aging stars gave birth to the nebula
Gemini Observatory, astronomers have published an international image of the nebula, which was formed by the interaction of a pair of aging stars. It is not clear, the explosion of the body which led to the ejection of interstellar gas, but it is clear that in the formation of both attended the celestial body.

Bacteria have taught robots to operate simultaneously
Engineers assembled in bacteria, the method by which you can synchronize the actions of large groups of robots. To do this, time must be a shared resource in the formation of which everyone will participate. Approximately the same working quorum sensing in bacteria, such as the formation of biofilms.

We found pliosaurs arthritis
Paleontologists have discovered traces of ancient dinosaurs pliosaurs disease arthritis. In life it could lead to the fact that the lower jaw in marine dinosaur was strongly skewed with respect to the top. This confirms the theory that dinosaurs, like their descendants - the birds were prone to diseases of the joints.

Graphene has a photodetector
Spanish scientists have decided to use a combination of graphene and quantum dots to create a high sensitivity of the photodetector. By itself, single-atom carbon is poorly suited to a photodetector, so the authors have dealt him a mixture of crystals of lead sulfide, with quantum properties.

Telomerase rejuvenated adult mice
Scientists have found that telomerase gene therapy may increase the life span of adult animals. The researchers injected mice with a specially crafted virus containing the gene for the enzyme, the reducing ends of chromosomes. In the case of yearling animals, life expectancy increased by 24 percent.

Mathematician closer to solving the problem of Goldbach
Mathematician Terence Tao (Terence Tao) has moved into a small proof of (ternary) Goldabaha problems. It reads as follows: to prove that every odd number greater than five can be represented as the sum of three primes. Tao was able to prove that any such number can be represented as a sum of not more than five ordinary.
