Introduced genes break free

12.06.2009

Opponents of the widespread use of genetic engineering in agriculture have repeatedly expressed concern that genes artificially inserted into cultivated plants to increase their yield, resistance to pests and diseases, or to enhance other beneficial properties, can be transferred to other plants.

The consequences of such spontaneous gene spreading are difficult to predict. However, supporters of genetically modified products insisted that such a transition was impossible. Indeed, recently, geneticists from the University of the Mexican capital found genes from genetically modified corn in common varieties growing nearby.

True, the transition of extraneous genes happens infrequently. They are found in only one percent of nearly 2000 samples of corn grains collected in the fields of Mexico.

Geneticists point out that foreign genes are not so easy to identify, this can not be done in every laboratory. Therefore, to monitor an unsafe process, it is necessary to organize a wide monitoring network.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Vivo 2 Wireless Headset for Athletes 10.11.2022

BBK subsidiary Vivo has launched a new wireless neckband headset in China. The Vivo 2 Wireless Sports Headset uses a neck strap, which is excellent, but what should stand out more is the 12 hours of music playback sustained by the battery under the hood. The product is extremely affordable as it starts at just 119 yuan ($16).

Since it's a relatively cheap product, don't expect much from it in terms of configuration, but that's not the case. Headphones with a neck brace are very light, weighing only 18 grams. It adopts the exclusive design of horn ears, which can fit snugly in the ear without any discomfort. Since these are sports headphones, it is important that they fit snugly around your ears.

The built-in 11,2mm moving coil is equipped with a polymer diaphragm. It also uses a Japanese Daikoku copper-clad aluminum voice coil to improve high-frequency sound output. The headset is also configured by the Vivo Golden Ear acoustic team to balance the three frequencies.

The Wireless Sports Headset 2 uses the Bluetooth 5.0 chip, and the audio latency during gaming can be reduced to at least 80ms. The high-sensitivity microphone designed in the headset's built-in control position supports noise reduction during calls, making daily calls and voices in games clearer.

As already noted, the headphones support up to 12 hours of music playback when fully charged. Even if the battery is dead, there is no reason to worry because the headphones have a flash charging function. A 10-minute charge can provide up to 3 hours of music playback, which is great.
