Andrey Aderekhin reports: - I managed to get acquainted with the unpublished diaries of the world famous inventors of the Kirlian spouses, whose discoveries still bring new sensations
The new underwater drone "Status-6", which is capable of carrying a nuclear charge on board, is a "cobalt bomb" and could turn entire continents into lifeless territories
For a long time, it was believed that the laws of quantum mechanics only apply to tiny objects like photons. However, physicists have proved that very large bodies (by the standards of the molecular world) can obey these rules.Probably, you have heard more than once about the thought experiment, which at one time was formulated by the Austrian physicist Erwin Schrödinger - the same one with a cat, a box and a radioactive isotope
Physicists have created a controlled magnetic field with an induction of 1200 Tesla, which is 400 times more than the magnets of modern medical tomographs and about 50 million times more than the natural field of the Earth
A magnetic monopole can exist not only as a mathematical abstraction. Scientists have discovered traces of a magnetic monopole - the source of the magnetic field, the existence of which is denied by modern physics
Within five years, we will be able to extract almost unlimited energy from "miniature suns", some startups say. We are talking about fusion reactors that can provide a lot of cheap and clean energy
So, it should be said right away that today it is a theory. However, this is not a perpetual motion machine, not BTG and the like. From the point of view of physical laws, there is no violation here. So, who knows, maybe in a dozen or two years, we will all be watching this unusual idea work
Sometimes scientists need to control the process of mixing liquids in such small containers that it will not be possible to lower even the thinnest needle or even hair there. Meanwhile, it is very important to control the diffusion rate of molecules in so-called microreactors in order to create new effective drugs, conduct some biological experiments, and even quickly diagnose diseases
"Generating Light from Darkness" is the title of a new article published in Joule magazine by Aaswath Raman and colleagues at the University of California, Los Angeles (UCLA). And although the effect used in their device has long been known and widely exploited in technology, the concept itself really allows you to generate energy in complete darkness, while simultaneously reducing the cost of cooling and air conditioning buildings
A team of researchers from Spain and the USA has found a new property of light - "self-torque".In their article published in the journal Science, the researchers describe how they discovered the new property and also talk about its possible uses
When light hits your hand, you feel nothing but a rise in temperature. But in fact, light is able to move objects. And before it was only a certain type of laser. But not now
This experiment was done back in 2012. Used equipment that captures images at a rate of about a trillion frames per second - it's 35 billion times faster than a normal TV camera
Perhaps each of us at least once faced the need to replace a burned out light bulb. And although today there are many modifications of them, including those that last longer, they still have to be changed sooner or later. But the fire department employees of a small American town do not have such a problem, because their light has been on for more than a hundred years
Cancer used to be a death sentence. Today, seven out of ten patients live at least ten years after diagnosis. An SvD journalist met with some of the world's most prominent researchers and asked how close we are to solving the cancer puzzle. He also tells the story of one patient
Russian doctors decided on an experiment that will allow to grow a finger on a hand
Vaccination is one of the most effective methods for strengthening immunity (no matter how opponents try to prove otherwise)
Since the Foundation for Advanced Study (FPI) approved the liquid breathing project in 2016, the public has been keenly interested in its success. The recent demonstration of this technology literally blew up the internet
This wonderful invention allows humans to breathe comfortably underwater, like sea animals. Korean designer Jebyun Yong has developed something truly amazing. In fact - he managed to turn a man into a fish
While all over the world talk about the dangers of genetic editing, China is actively engaged in it. In the race for the technology of editing the human genome, the winner will be the one who not only actively invests in science, but is also the least willing to limit himself
The CRISPR / Cas9 genome editor is a potentially dangerous tool, the use of which can be accompanied by the emergence of many unintended genetic changes - writes the publication Nature Methods
One of the leading Russian specialists in the field of molecular biology and genetic engineering, Denis Vladimirovich Rebrikov, in an interview with the journal Nature, spoke about plans to conduct an experiment to create children with edited genes
In 1944, Columbia University geneticist graduate student Evelyn Witkin made an accidental mistake
An insulin-producing rooster, giant rabbits with a planting gene for growth, a curly ram that intermarried with … a spider. No, these are not characters from the wonderful garden of Dr. Salvator - the hero of the fantastic story Belyaev
In Tatarstan, the first in Russia multi-node computer network using quantum cryptography technologies was launched. The main advantage of such networks is that it is almost impossible to intercept information from them using traditional methods
The most common type of brain cancer is glioblastoma. Treatment for this condition usually includes surgery, chemotherapy, and radiation therapy
European scientists managed to come to the conclusion that one of the types of antibodies of patients with dengue fever is able to neutralize not only its own virus, but also its related Zika. Thus, specialists have a chance to find a cure for viruses
To understand how the human embryo behaves in the early stages of development, the researchers created a three-dimensional model from stem cells.A few weeks after conception, what will become your body in the future undergoes significant metamorphoses and grows both up and down
Geneticists have been using the CRISPR / Cas9 genome editor in animal experiments for a long time, but scientists from the United States were the first in the world to move to a new stage of testing: to experiments on humans
Last week, a team of researchers at Oregon Health and Science University edited human embryos for the first time using a technique known as CRISPR
New report from the US National Academy of Sciences shows the overseas scientific community is about to soften its stance on gene editing
A group of scientists at the University of Cambridge in the UK created an artificial mouse embryo for the first time, writes the Telegraph newspaper. Scientists have used two types of stem cells: embryonic and placental

Medical ethics expert William Harlbut of Stanford University made a statement back in January 2019 that Chinese scientist He Jiangkui had edited the genes of another child.According to Harlbat's assumptions, this child should be born in June or July
Scientists from MIT have solved the mystery of why the forced switching on of genes responsible for DNA repair does not rejuvenate the retina in mice, but rather kills its cells. Their findings were presented in the journal Science Signaling
Blood clots are the cause of a wide variety of (and often fatal) diseases. Of course, there are drugs for the therapy of thrombus formation, but with constant use they have one very unpleasant property: the development of bleeding
Computers don't exist in a vacuum. They solve problems and the problems they solve are solely determined by the hardware
