Editing of human embryos for the first time

27.07.2017

Oregon Health and Science University (OHSU) in Portland is the first in the United States to use technology that allows you to change genes in a human embryo.

The research involved modifying DNA in a large number of single-celled embryos using CRISPR gene-editing technology.

Although none of the embryos were allowed to develop for more than a few days - and there was never any intention of implanting them in the uterus - the experiments are a milestone in what may be the inevitable path to the birth of the first genetically engineered human.

By changing the DNA code of human embryos, scientists can remove or fix genes that cause hereditary diseases such as beta thalassemia. This process is called "germ-line engineering" because any genetically modified child will then pass the changes on to subsequent generations through their own germ cells.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Keyboard controlled by sight 08.01.2015

The United States Patent and Trademark Office (USPTO) has granted Microsoft a patent ?8,917,238 for Eye-typing term recognition.

We are talking about a new typing system on the virtual on-screen keyboard of mobile devices - smartphones and tablets. In a sense, the proposed solution is a "visual" analogue of the Swype technology, which allows you to enter a word by sliding your finger or stylus from letter to letter on the touch screen.

In the patented system, instead of registering finger movements, Microsoft proposes to track the change in the direction of the user's gaze using a camera integrated into the gadget. Based on the received data, special software will conclude what characters the user is looking at and what word he is trying to enter.

The system can be useful not only in smartphones and tablets, but also in wearable devices like smart glasses. However, there are some doubts about the accuracy and usability of the proposed solution. In addition, a gaze-controlled keyboard can have a negative impact on power consumption.
