The carnivorous plant Utricularia gibba, which inhabits freshwater aquatic environments and has the smallest genome of a multicellular plant ever sequenced, has revealed that non-coding DNA (misnamed junk DNA) might not be necessary for cellular processes . According to an international study in which the National Laboratory of Genomics for Biodiversity LANGEBIO has participated, 97% of the plant genome consists of genes and small DNA fragments that control them. That is, it happens just the opposite of other plants such as corn or tobacco, or in the human genome, where the genes that encode essential proteins represent approximately 2%, and the rest consists of genetic material known as non-coding DNA ( or junk DNA, which does not code to generate proteins).
At Ohio State University they have come to the conclusion that the photo we use on our Facebook profile is all that another user needs to form an impression of us. That is, the words with which it is described or the messages it publishes are not taken into account when evaluating how a person is on social networks, explains Brandon Van Der Heide in the Journal of Communication. In their experiments they found, among other things, that if a person uses a photograph as a profile image socializing with friends, even if they write that they are an "introverted" person, or that "they feel happier locked up in their habituation with a book", those who visit your profile identify and describe you as outgoing.
Until today, the most accepted belief was that 4,500 million years ago a gigantic object collided with the Earth and, from the detached fragments, the Moon was born; and that the impact caused such heat that all the hydrogen evaporated and was lost in space, leaving both the Earth and its satellite dry. Later, the water returned to Earth in meteorites and to the Moon in comets.
Although they share the same genes and grow up in the same environment, identical twins develop different personalities and behave in increasingly different ways as they grow older. Scientists at the Salk Institute in La Jolla, California, have conducted experiments on mice to find out if these differences are reflected in the brain. And they have concluded that the time each twin spends exploring throughout their lives translates into significant differences in the number of neurons in their hippocampus, an area of the brain involved in learning and memory.
Although the composition of dark energy remains a mystery, scientists have already started taking short but decisive steps to understand dark matter. In April, Dr. Samuel Ting, the 1976 Nobel Prize in Physics, announced that the? Alpha Magnetic Spectrometer, a? The particle detector that has been operating on the International Space Station for two years has counted more than 400,000 positrons, the antimatter of electrons.
It has a round head, bipedal and the size of a dog. This was Acrotholus audeti, the new species of herbivorous dinosaur discovered in Alberta (Canada) and belonging to the family of pachycephalosaurs, a name that means "thick-headed reptile." As the paleontologist David Evans and his colleagues at the University of Toronto have found out by studying its fossil remains, the reptile lived 85 million years ago, measured approximately 1.8 meters from the tip of the tail to the head and weighed 40 kilograms. It is the largest known dinosaur with a bony skull in North America, and possibly the world, according to scientists in the journal Nature Communications.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
