In the future, if someone leaves just one hair at the crime scene, the CSI will be able to get the whole picture of the offender. A promising US – Belgian technology, which may be added to the “arsenal” of forensic investigators in the near future, allows to recreate a three-dimensional model of the face of a person only from the traces of genetic material (DNA).
Although the technique is still at an early stage and allows creating portraits without great precision, in the future, when further improved, it could provide significant assistance to the police and Continue reading
In the late 80s scientists from Osaka University in Japan observed some unusual sequence repeats in the DNA, while studying the gene of a common bacterium.
These sequences, which proved to be part of a sophisticated immune system used by bacteria to fight viruses, give scientists an unprecedented opportunity to rewrite the code of life. Just a year ago, it was discovered that bacteria can be used to perform specific changes in the DNA of plants, animals, and people.
The molecular system known as Crispr has already made the production of genetically modified animals a much easier process. The first experimental results Continue reading
The U.S. federal agency Food and Drug Administration (FDA) begins its consideration of biological procedures which, if successful, will allow to create genetically modified people, reports in an article for The New York Times Marcy Darnovsky, executive director of the Center for Genetics and Society.
“This is a dangerous step”, warns Darnovsky. According to her, these methods will “change all the cells in the bodies of children Continue reading
Renowned geneticist Craig Venter, one of the pioneers of synthetic biology, claims that the technologies needed to teleport living beings already exist. However, till now he is talking only about viruses and bacteria. But maybe someday it can be true for humans too.
In 1995 a group of scientists from the J. Craig Venter Institute, JCVI, launched a project “minimal genome“, whose goal was to leave in the genetic code only the essential information for the existence of a living organism. The research was based on the bacterium Mycoplasma genitalium, which at that time had the smallest genome of all known (482 genes). In 1999, Venter reduced the number of genes to 382, creating a Continue reading
American biologist claims that genes can be affected by signals located in the external environment of the cell, such as thoughts, feelings and emotions.
Cell biologist Dr. Bruce X. Lipton (formerly professor of medical courses in high school and now scientific researcher) was one of the first scientists who detected this effect. Having performed a series of experiments, he revealed that the cell membrane is an organic analogue of a computer chip.
Although these views conflict with the scientific doctrine, which states that genes are those that control behavior, similar publications of other researchers have strengthen this view. Continue reading
The relationship of genes and nutrition is one of the hottest areas of research worldwide. The goal of the scientific community is to find the way to match our nutritional intakes with our genetic background to achieve maximum health.
To understand the potential of this method, let’s take a walk in the future, and possibly in the near future. Let’s imagine that in some years from now the state of your health forces you to correct your diet and form more good eating habits. Continue reading
Fear can be transferred from parents to children and grandchildren, claim U.S. researchers in their article published in the journal Nature Neuroscience.
A scientific group of the Department of Psychiatry, Emory University in Atlanta, led by Dr. Brian Dias, conducted experiments on mice and found that a traumatic event can leave an imprint in the DNA of sperm, which in turn can transfer phobia and thus affect the brain structure and behavior of future generations even if they have not experienced the same painful event.

Science in 2013 played a more important role than ever. At the same time, many intriguing discoveries were made. Here is a list of five major scientific discoveries according to the magazine National Geographic.
1. Space has become more ‘crowded’
In 2013 researchers from California Institute of Technology suggested that there are no less than 100 billion exoplanets in the orbits the Milky Way’s stars.
Obviously, not all of them are suitable for living. The November report from NASA Keck Observatory suggests that one out of five stars may have Earth-like planets in their habitable zone. More recent climate studies of habitable zones claim that this probability may be too high although there are still a very large number of potentially habitable planets. Continue reading
2013 is a year that brought numerous medical and scientific achievements. However, three of them, in accordance with the scientific community, are expected to change our lives for the better.
The hidden second code in DNA
U.S. scientific team led by Professor of Genetics School of Medicine University of Washington John Stamatoyannopoulos identified a second genetic code in the DNA.
In accordance with the research team, the genome uses the genetic code to “write” using two different Continue reading
New Scientist magazine published a series of articles about the 10 major events that are likely to happen in the field of science and technology in the coming year.
Space is getting closer
In 2014, two spacecraft that will help people finally reach Mars will be tested. In September, NASA will launch spacecraft Orion, designed for deep space missions, in a 4-hour flight around the Earth.
Also next year the first launch of the rocket Falcon Heavy, developed by a private company SpaceX, will take place. It is able to Continue reading
