glowing plants

01.05.2020

Scientists have transferred genes from fungi to plants, causing them to glow intensely in the dark. In the future, this technology can be applied to many ornamental plants.

An international team of scientists from the UK, Austria and Russia found that the bioluminescence found in some fungi was metabolically similar to some of the natural processes found in plants. The scientists were able to transfer DNA sequences into tobacco plants, causing them to emit a bright green glow. The researchers found that this glow continued throughout the life cycle of the plant, from seedling to maturity.

Bioluminescence - the emission of light by an organism - occurs in a wide range of animals and microorganisms, including some fungi, insects, fish, marine invertebrates, and bacteria.

"We're showing that you can transfer four genes from these glowing mushrooms into plants - and link them to plant metabolism - so that plants glow in the dark," said Karen Sargsyan, one of the study's lead authors.

This technology can be used for a variety of purposes, including decorative luminous plants and flowers. Other plants - including petunias and roses - can be adapted to glow.

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, ... >>

Self-driving cars from Google 10.10.2012

California Gov. Jerry Brown signed into law a law giving the green light to self-driving cars on the state's roads. The law defines the scope of safety and criteria for testing automatic machines. The driver who has the appropriate rights will still be in place - if necessary, he will be able to take control of himself.

“Today we are seeing the science fiction of a self-driving car becoming the reality of tomorrow,” Mr. Brown said. “Those who get inside such a car and find out that the car drives itself will be a little scared, but they will cope with it.” .

According to Google, which is promoting the idea of an "unmanned" car, road safety will only increase. Google has 12 of these cars that have already run a total of 300000 miles. During this time, only one minor incident occurred with the participation of such a machine. According to Google, driver intervention required to avoid a dangerous situation was required on average once every 50000 miles. Google Cars uses cameras, lasers, radars and other sensors to monitor traffic and navigate. Unlike a human driver, the computer does not get tired or lose concentration. In addition, drunk driving and recklessness are excluded.

According to the head of Google, "autonomous cars" can appear on the market within a decade.
