The mantis in the announce photo received 3D points, and is absolutely free. At the same time also showed to an insect the 3D movie (the truth, not "Avatar"). It is made to prove existence of stereoscopic sight at insects which developed irrespective of vertebrata. Yes, monkeys, cats, mice and even toads have a stereoscopic sight — it is proved for a long time. At the majority of vertebrates such type of sight. But insects? How it is possible to define sight type at them?
To obtain the reliable evidence, scientists from university of Newcastle decided to take a species of insects with the most developed visual device and excellent reaction. It is about mantises (by the way, they also only among insects who can turn the head in the different directions voluntarily). For work with mantises the interesting technique which basic element — 3D points was created.

In article the hypothesis of a life origin in the Universe is offered. The assumption that the logic of laws of a structure of the world exists out of the Universe, i.e. out of space and time is its cornerstone. The offered hypothesis is unprovable also, as well as the majority of cosmological theories, however it seem to me plausible.
The Universe is a result of a logical output from nothing
We got used that scientific theories are created by people. Justice of theories is confirmed by practice. The part of theories is wrong, the part has narrow range of applicability. However among them there are true theories which are never refuted, and are only specified over time. It is probably possible to carry to them laws of Newton, Euclidian geometry, the object-oriented approach in programming. True theories are created not by people. They are only opened by them. And there were they always, including to the Big Bang.
The main idea of article consists that true theories exist until their opening, exist irrespective of space and time, are identical in all Universes and at their absence. I will explain this assumption.

The second and third parts (the first part) of the narration about new growths and cancer in particular will be devoted to "ordinarier" problems — namely to diagnostics and treatment, and also it will be a little told about the most often found types of onkologiya. At once I will tell that this post was given me strongly more difficult, than the first part as not absolutely corresponds to my specialization. But as I was asked to write about it, I tried.
In Russia and the former republics of the USSR the term "oncological vigilance" introduced in 1948 by Savitsky A.I. for the first time is widely used., but its modern determination belongs to 1979, and it was entered by Peterson B. E. as "oncological literacy". It includes 5 points:
1. Knowledge of clinical symptoms of malignant tumors at early stages. 2. Knowledge of precancer diseases and principles of their diagnostics and treatment. 3. Careful inspection. 4. The exception is unreasonable optimism — on the contrary, the doctor is obliged to think of a possibility of an atypical course of a disease. 5. Knowledge of the principles of the organization of the oncological help and the direction of the patient with the found or suspected tumor in specialized oncological institutions.
The national scientific fund (National Science Foundation) provided to the Center of sensomotorny neural engineering (Center for Sensorimotor Neural Engineering) at University of Washington a grant of $16 million in size. Financing is provided to design team of the latest technology allowing to recover functionality of the paralyzed extremities.
The technology allows to solve a problem of injuries of a spinal cord when the electric signal to extremities is not transmitted as integrity of the carrying-out fabric is broken. According to the scientists who are engaged in development of new technology, their implant is the bridge transmitting signals from the sender (brain) to the receiver (extremity).
In the modern world cancer is one of basic reasons of death. According to WHO data in 2012 died 8.2 million people around the world from cancer, and the quantity of the new registered cases same year made about 14 million. By amount of death cancer concedes only to heart diseases. For this reason, it seems to me, it will be rather interesting and it is useful to try to deal with this disease that we together also will try to make.
2 years, 2 months ago Это Дилан, умерший в июне пес из Великобритании
Супружеская пара из Великобритании не пожалела 67 тысяч фунтов стерлингов (около 100 тысяч долларов США) на клонирование своего, уже умершего, пса. Похоже, пара не жалеет о своем поступке, поскольку на днях от суррогатной матери родился щенок — клон питомца. Любимый боксер парочки скончался из-за опухоли в мозге.
Клонированием занялась компания Sooam Biotech Research Foundation, которая относительно давно предлагает свои услуги по клонированию питомцев. На данный момент это единственная такая лаборатория в мире.
We continue a series of interview with leaders industrial the practician of DataArt. Our editors Daniel Lurye and Vadim Mazin talked about medical technologies to Roman Chernyshev, the leader of medical practice. Discussed medical wearables, "smart prostheses", conservatism of the industry, Big Data in medicine and many other things.
— Who now main in the market of a medtekh — startups or corporations?
— On this question there is no simple answer. The medicine owing to inevitable conservatism very slowly adapts to new technologies. Here — the huge potential, a set of new ideas and technologies which promise to invert everything upside down and to make medicine absolutely another, but this updating will take very long time. All innovation ideas pass through several long stages — from origin in startups and academic institutions where they are rolled, but have no great influence on the industry, before understanding of potential by big players who already have resources for change of a landscape and transfer of innovations in a mainstream.
I will give an example. There was few years ago a set of startups which created solutions for a telemedicine — any platforms by means of which people could get medical advice far off. It was incredibly popular direction, however widespread introduction did not happen. Now the situation gradually changes — the industry begins to accept rules of the game. Just a month ago one of the world's largest insurance companies that we developed such project — a solution for a telemedicine addressed DataArt. Here they, with their resources, with their penetration anywhere and everywhere and serious influence on the industry, have a chance to cardinally change all developed rules. And only few years ago it it was absolutely uninteresting.
I think, in five years where now startups were proved, there will be big companies. But there will be new niches which will create and will occupy new startups. This process also moves the industry forward.
The group of the Korean scientists of several institutes which are going in for neuromedicine and researches of activity of a brain found the chemical eliminating symptoms of Alzheimer's disease and improving cognitive capabilities at mice. Substance mice were given, just dissolving it in water.
The preparation which made such surprising impact on a brain of mammals is a quite famous EPPS connection (or HEPPS — 3-[4-(2-Hydroxyethyl) - 1-piperazinyl] propanesulfonic acid). In biochemistry and biology it is used as the buffer solution saving acidity when adding in mix of acids or the bases.
The science did not set the reasons and course of Alzheimer's disease yet. Symptoms of an illness are frustration of short-term memory, violation of the speech and cognitive functions. It is known only that about 1% of cases of diseases occur for the genetic reasons. Alzheimer's disease – the most common cause of dementia.
Key feature of an illness — accumulation of amyloid plaques and neurofibrillary tangles in brain tissues. While the scientists struggling with an illness are able to stop in certain cases formation of new proteinaceous plaques — but it was not possible to wash away already available plaques from a brain yet.

We know about two types of fatty tissue long ago — "white", reserving fat, and "brown" which burns it. Doctors were long sure that only babies have brown fatty tissue, but found out that adults have it also, but in smaller quantities. Seven years ago scientists found beige cages — they, as well as brown, process fat.
Researchers from Kyoto University found out that cod-liver oil transforms zhirosokhranyayushchy cages to zhigoszhigayushchy cages which can reduce a weight set in the middle age. Cod-liver oil activates receptors in a digestive tract, activate sympathetic nervous system and start lipoliz.

We welcome you on pages of the blog iCover! As the joint group of researchers of the Washington and Californian universities proved, change of structure and a form of molecule DNA involves change of its electrical conductance. Such dependence, according to scientists, allows to use molecule DNA as the microscopic electromechanical switch which will be able to be used in nanodimensional molecular computing devices of new generation.
