THINGS AND SUBSTANCESFlatland TravelSorokin P.B."Graphene: Materials of Flatland" – this was the title of the Nobel lecture by Konstantin Sergeevich Novosyolov, delivered by him in 2010. The title contains an allusion to the fantastic parable of the English theologian Edwin Abbott "Flatland: A Novel in Many Dimensions", first published in 1884 – the two-dimensional hero of this book discovers the three-dimensional world. In our world, it was Konstantin Novoselov who was one of the discoverers of Flatland, a new country in the scientific world, in scientific terms, the field of two-dimensional materials.

PROBLEMS AND METHODS OF SCIENCECollider pentaquarksFeygin O.O.The second run of the Large Hadron Collider (LHC), which began on June 3, 2015, made it possible to obtain a record doubling of the particle energy to 13 teraelectronvolts. This generated a flood of interesting data. In particular, all previously discovered particles of the Standard Model were discovered, except for the Higgs boson, the identification of traces of which in the newly obtained data will take some time. And of the new, the most interesting turned out to be the long-awaited find of an amazing particle – pentaquark.

HEALTHAre sweet tooths curable?Reznik N.L.Man, like most mammals, loves sweets, and this love is innate. Sugary foods are rich in glucose, an essential source of energy. So that the animal diligently searches for high-calorie healthy food, and does not stuff the stomach with anything, when eating the "right" food in one of the brain regions, the ventral striatum, dopamine is released, which causes pleasure. So eating pleasure is not an end in itself, but a mechanism that reinforces proper eating behavior. And the purpose of nutrition is to maintain energy homeostasis.

PROBLEMS AND METHODS OF SCIENCEPsi steroidsZhukov D.A.In one article by the great scientist Hans Selye, among other things, the sedative effect of progesterone was described. It must be said that the author of the concept of stress did not pay attention to this experimental fact. Selye was not interested in behavior, let alone psyche. And he also neglected the role of the nervous system in the stress response he studied. Be that as it may, the effect on the behavior of progesterone – the female sex hormone – has not attracted the attention of the scientific community. And so it was for more than forty years, until in the 1980s they discovered that steroid hormone metabolites act directly on the brain, and, moreover, clearly change the behavior of experimental animals.

QUESTIONS – ANSWERSDoes watermelon have the effect of Viagra?Viktorova L.Indeed, some websites refer to watermelon as the natural viagra. Is there a chemical basis for this?

QUESTIONS – ANSWERSHow to remove gum from hair?Viktorova L.Chewing gum in your hair is a real disaster. Most often, this problem is solved with scissors. However, there are gentle ways to keep in mind.

QUESTIONS – ANSWERSWhy is chocolate dangerous for animals, but not for humans?Viktorova L.A strange question, you might say. Who would dream of feeding dogs and cats chocolate? But strange only at first glance. In September last year in the state of New Hampshire (USA), two she-bears and two cubs died – they were poisoned by chocolate.

The rhizome of life: a new round of the theory of evolutionSo, the spiral went on a new round: Didier Raoul courageously declared Darwinism obsolete. I must say that this statement in itself is more trivial than striking. Could the natural-scientific concept, whose age has long gone over a century, have not become obsolete in anything?

ReflectionsAbout the folly of evolutionBagotsky S.V.One could ignore individual citizens who deny evolution. However, the prevalence of this opinion testifies to the decline in the authority of science in the eyes of the public. For many people, religious writings turn out to be more authoritative sources than scientific works. Therefore, criticism of the creationist masters and their views seems to be a highly urgent task.

EARTH AND ITS INHABITANTSStegosaurus: he and sheAnina N.At the end of the Jurassic period, stegosaurs lived on Earth – herbivorous dinosaurs decorated with a double row of bone plates along the ridge. After 150 million years, researchers discovered sexual dimorphism in these animals.

RESOURCESInto the forest for berriesKomarov S.M.Forest is wood, it is a raw material for furniture makers, builders and wallets, it is fuel, forests need to be involved in economic circulation, some say. What do you mean, the forest is our everything, it is the basis of biodiversity, it is a sink of carbon dioxide, it is the lungs of the planet, it is a global thermostat, the less you touch it, the better, others argue. The forest is a breadwinner and a healer, the forest is abundant, and if you take a little from it, you can live in harmony and not destroy anything, still others offer a compromise. It is about this third way of interacting with the forest, about the use of what is called in the documents "non-timber resources", and will be discussed in this article.

THE JOY OF LIFEMushrooms from different sidesGoldreher M.The Slavophile and naturalist of the 19th century, the writer S.T. Aksakov. In those days, the great Russian forest dominated the entire territory of the Russian Empire, and its gifts for many people were more important than agricultural products.

ABOUT THE SUBSTANCE IN SUBSTANCEFrom willow bark to the Nobel PrizePaevsky A.It would seem, what could be simpler, more boring and more famous than aspirin? The author of this article has been in science journalism for exactly ten years. And the main thing that I managed to understand during this time is that there is no more interesting topic than the one that “everyone knows about”.

WHERE IS YOUR NAME?Urea, Barbara and VeronaLeenson I.A.Chemists have two legends about the name of barbituric acid. And both are associated with the famous German chemist Johann Friedrich Wilhelm Adolf von Bayer (1835-1917), winner of the 1905 Nobel Prize in Chemistry. Among his outstanding works is the first complete synthesis of indigo. One legend says that in 1862-1863, when Bayer was researching urea derivatives, he courted a girl named Barbara. He decided to immortalize this name by discovering a new acid, but at the same time he wanted to include urea in the name. This is how the ending "leveled" appeared.

BOOKSTransparent Society, or Trying to Count Your FingersLyubarsky G.Yu.Numerous perplexities about how our society is changing and what its citizens support remain groundless until it is clear what kind of society we are talking about. And the answer should lie not only in defining the political system or caustic and memorable nicknames, but in simple and ordinary knowledge of what kind of society it is, of what social strata it consists.

REPORTAGEIn the Far East"Mikhailov K.G.So, the Vostok Marine Biological Station is a subdivision of the Institute of Marine Biology. A.V. Zhirmunsky Far Eastern Branch of the Russian Academy of Sciences in Vladivostok (abbreviated as IBM) – founded in 1970. The station is located on the shores of the picturesque Vostok Bay, in the Peter the Great Bay system, in the vicinity of the Avangard village, about 15 km from Nakhodka (if by road, then 40 km). My colleagues say that in general appearance the biological station is similar to similar stations in Scandinavia, for example, the Norwegian Fledevigen.

NANOFANTASTICChief InspectorKnyazev Victor- I asked you for a meeting to ask one question. What do you say if I offer you the position of chief inspector of your galaxy?- This is a joke?- This is not the first time we have spoken with you. Do I look like a joker?

THINGS AND SUBSTANCESStalactites next to manKazdym A.A.Ask a person what a stalactite is, and he will say – it is something like that in caves, deep underground. And he will be very surprised if you tell him – stalactites are quite often found on the surface of the earth, for example, in the center of Moscow, on the building of the Central Post Office. There are quite a few anthropogenic stalactites, that is, those arising as a result of human activity, although they have to live in more diverse and unstable conditions than their underground brothers.

WHAT WE EATPhysalisRuchkina N.The Indians cultivated different types of physalis even in the pre-Columbian era. However, some researchers do not exclude that they collected wild physalis. Then the plant was brought to North America, Africa, Australia, the Pacific Islands, Asia and Europe.

MEMORYAbout Boris Gorzev – scientist, writer …P.Yu. Chernosvitov

UNKNOWN LEMThe moon is like a market. Global globalizationStanislav LemThe technological advancement that the landing of man on the moon became was the result of the desire of the Americans to overtake the Soviets in space competition. The project, launched by President Kennedy, was worth about twenty-five billion dollars at the time. On the moon after him there were only traces of Armstrong’s boots, as well as the remains of vehicles.

FANTASYService mageLoginov SvyatoslavTerim hardly communicated with his own people, except that matters concerning everyone were announced. But that didn’t happen in a long time. Therefore, Terim was very surprised when in the middle of the only room, almost blocking the passage, a negotiating column appeared. Most of all, it resembled a neatly cut piece of lightning: glowing, overflowing with discharges. A thick thunderous smell spread throughout the house, promising a burn of the lungs and pain in the eyes. These promises usually did not come true, the pillar appeared rarely and for a short time and could not cause significant harm to health. The sorcerers quickly resolved pressing issues and forgot about each other until the next time.
