Scientists: Dinosaurs died out because of the growth of the Earth's gravity

Scientists from Vladivostok suggested that the extinction of the dinosaurs contributed to the growth of the Earth's gravitational force. His hypothesis is confirmed paleontologists mathematical calculations.

According to one hypothesis, the authors Anatoly Drozdov, has long minds from around the world concerned about the fact that the animals of the past, the existence of which is undeniable, now hardly able to survive because of the increase from the time the force of attraction. It is the first of the giants, weighing dozens of tons.

Scientists from the Institute of Marine Biology, Russian Academy of Sciences reviewed the available information on the evolution of over 150 million years, 11 species of the largest land animals. The result was that the dinosaurs appeared and evolved in completely different circumstances - when Earth's gravity was 2,079 times smaller than now.

Moreover, according to scientists, dinosaurs became extinct because of a sharp (in geological terms) changes in gravity. It happened about 60-100 million years ago due to the accumulation of the past 100 million years the Earth's surface large amounts of cosmic dust - the mass of the planet has increased and increased the force of gravity, which the dinosaurs could not move.

Why bullfinches fly it for the winter and where to fly in the spring?

Bullfinches - sedentary birds, and not in some distant lands, they do not fly away in the spring. It turns out, bullfinches spend most of their lives in coniferous forests, and in the winter gather in flocks and fly in search of food in the next town. All peeled rowan berry and left without food sparrows, bullfinches voracious fly back. It is also true in the summer in the woods to see the birds is very difficult: they do not cry out loud all the time hiding in the trees.

It looks like a tree frog in Alaska, it freezes in the winter, stopping the heart, and wakes up in the spring.

Scientists have found a rat with a pig nose and a very long pubic hair

In the north of the island of Sulawesi (Indonesia) zoologists have discovered a new type of rostellar rats differ unusual appearance. About predatory rodent with a narrow mouth, nose like a pig nose, and very long hair to the urogenital area, described in the journal Journal of Mammalogy, and briefly reported on the opening of publication Mashable.

Animals found in a trap set on Mount Dako in 2013. Big nose, elongated hind legs and an unusually long hairs immediately indicated Theriology Kevin Rowe (Kevin Rowe) that before him - unknown to science species. Creature weighs about 250 grams, and its length from nose to tail reaches 45 centimeters.

Similar pubic hair found in some Australian marsupial rat (eg, potoru). Scientists do not know what is the function of a particular anatomy. "Probably, the hair somewhat assisted reproduction. They are both males and females, such as long, as the whiskers. They do not look like pubic hair man "- said Rowe.

In addition, a new type of rodents Hyorhinomys stuempkei are extremely narrow mouth opening: they do not have some of the jaw bones, which help other mammals chew food. Rather, they swallow their prey (worms and insect larvae) in its entirety.

Unlike most rodents, the front teeth are painted in brown and slightly angular cutters Hyorhinomys stuempkei - white and pointed, adapted to prokusyvaniyu production.

Rowe is involved in a major research project to study the diversity of mammals Wallace (biogeographic region, includes a group of islands separated by deep straits of the Asian and Australian continental shelves) and Australia. In Sulawesi, scientists have discovered many new species of rodents, including almost devoid of rat teeth and "amphibious" rat.
