The development of German students will not allow you to “miss” life
Students from Germany developed the device Augenblick, which removes the surrounding world, while you blink. It is a pair of glasses equipped with a camera and sensors that react to the contraction of the muscles around the eyes.
Augenblick is the diploma project of Manasse Pinsuwan and Rene Henrich of the Bremen Higher School of Art. According to the developers, the camera captures all that we miss when closing our eyes when blinking a thousand times a day. The device records each individual frame that passes its media. A high-sensitivity sensor responds to the contraction of the muscles around the eyes, perceiving it as a signal to start recording. Recording stops only when eyes are opened again.
Creators see potential in their project. The installation of the video showed that a person “loses” thousands of points a day, which can form a nearly diary documentary about the life of the owner of the device.

The NASA spacecraft probe confirmed the existence of geysers on the satellite of Jupiter, flying straight through one of them. The giant plume of water vapor rose from the icy surface of Europe and reached a height of almost 170 kilometers. The discovery reinforced the confidence of scientists that the satellite of Jupiter Europe is the most promising place for living in the solar system.
Europe – one of the four largest satellites of Jupiter, discovered by Galileo. In 2016, the sensors recorded on the surface of Europe what looked like a trail of water vapor. The presence of geysers on the satellite would explain these data, and now scientists have confirmed their theory. If such geysers are distributed in Europe, NASA and the European Space Agency will send there special devices for searching for extraterrestrial life in the ocean, which is under the surface of the satellite and contains twice as much water as all the oceans on Earth.
Conditions on Europe are not the most favorable. Extremely low surface temperature and massive gravity suggest that the existence of organisms is possible only near the hydrothermal openings on the ocean floor. William Sparks, an astronomer at the Space Telescope Institute in Baltimore, says that Europe is almost completely absorbed by a salty ocean that is covered with ice crust, but this is really the most promising place to live in the solar system.

American neuroscientists were able to transfer memories from one organism to another by injection. The results of the experiment on mollusks showed that animals reacted to an external stimulus that they had never encountered, just like those who already had this sign.
Scientists of the University of California in Los Angeles (USA) for two days worked on molluscs Aplisia (Latin Aplysia) with weak current discharges. After the material from the animal’s brain was introduced to other individuals who had never before experienced electricity. Surprisingly, they reacted to the touch of the wire in the same way as their experienced congeners. Professor David Glanzman suggests that memory can be stored in ribonucleic acid (RNA), which along with DNA is contained in the cells of all living organisms and plays an important role in coding, reading, regulating and expressing genes.
The results of the research show that memories can be physically transferred through an injection. According to experts, in the future this can lead to the appearance of “memory pills” or special jabs of memories. The authors of the study say that the new technology can block unwanted memories in the treatment of psychological trauma or post-traumatic stress disorder.
Archaeologists may have found the answer to the question, why the people of the glacial period suddenly began to create realistic and detailed drawings on the walls of the caves. The authors of the new study argue that the ability of people to reproduce what they see is so closely related to autism.
About 30,000 years ago, on the walls of caves throughout Europe, along with primitive drawings, very realistic images of bears, bison, horses and lions appeared (for example, in Shove cave in southern France). Researchers at York University (England) studied the data of scientists who tried to identify the connection between artistic talent and drug use. According to them, the ability to focus on details is a common feature of all people with an autism spectrum disorder. This allowed the realism of the ice age to flourish.
Dr. Penny Spinks (Penny Spikins) from the Department of Archeology at York University notes that the ability to focus on details determines the realism of the picture, and this feature is very common in people with autism and rarely occurs in people without it. The theory that the high degree of detail of the ancient drawings is caused by autism is, according to the authors of the study, a convincing explanation.
Scientists have found out that the gender of the embryos of turtles is responsible for the temperature of the nest, not the sex chromosomes. A temperature-sensitive gene was found, which corresponds to the embryo of turtles for belonging to the male or female sex.
Scientists have long been trying to explain how the temperature regime can influence the formation of sex in turtles and other reptiles. Experts from the Duke University School of Medicine (US), together with a group of Chinese researchers, used the data of the Kdm6b gene, which manifests itself differently in the development of female and red-bellied turtle males. The scientists “turned off” the sex gene with the help of viruses, and then monitored the development of turtle embryos at a temperature of 26 ° C. Usually, at such a temperature regime, males form in the eggs, but instead 80% of the surviving embryos became females.
Researchers, however, say that the complex process of sex formation can not be reduced to one gene. Among reptiles there is a huge number of various factors of sex determination. Even if Kdm6b is an important gene for the sex of one species of turtle, it is likely that other genes will work for other reptiles. It is also important to remember that the experiment was conducted under laboratory conditions, while the eggs of wild turtles are subject to different temperature fluctuations. This means that in reality everything is much more complicated than any theory can suggest.
Scientists managed to shoot on video one of the rarest and unusual jellyfish. The study of this species has always been complicated by its natural habitat on the ocean floor.
Originally, the deep-sea jellyfish type Deepstaria enigmatica was discovered in the 1960s. Since then, he has met in wildlife very rarely – in recent years, only a few copies have appeared. Scientists know very little about the behavior of these jellyfish, their diet and reproduction. In November last year, a team of researchers using a remotely operated device Hercules discovered a living Deepstaria enigmatica off the coast of the island of San Benedetto in the Pacific Ocean. The ultra-sensitive camera was able to make video in very low light conditions under water at a depth of about 974 meters.
From a distance the jellyfish looks like a plastic bag. Most jellyfish use tentacles for hunting, but Deepstaria enigmatica relies on another method. It is assumed that the jellyfish just wide open its dome and catches the victim in it, as in a sack.
Scientists note that in recent years, significant advances have been made in the field of deep-water shooting technology with low illumination. These achievements indicate prospects that will lead to the discovery and description of more unexplored species.
