LG will also sell music

31.01.2008

In the summer of 2008, LG plans to launch a free music service for LG mobile phone buyers and then open its own online audio content store.

Under an agreement with London-based music service Omnifone, as reported by CyberSecurity, all purchasers of LG phones will receive a free one-year subscription to Omnifone's digital content library files. Going forward, LG intends to do online trading on its own by opening its own MusicStation Max store.

The company hopes to reach agreements with all the major record labels. Probably, such a "musical" online expansion of the South Korean electronics manufacturer was caused by the active actions of the Finnish company Nokia, which opened the Ovi.com online store and bought a number of new web services, as well as the successful operation of the iTunes online store owned by Apple.

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, ... >>

The secret of adaptation of the Colorado potato beetles is revealed 05.02.2018

American geneticists for the first time deciphered the DNA of the Colorado potato beetles and identified several genes in it that are responsible for the unusually rapid adaptation of these insects to a new climate and ecology.

Colorado potato beetles (Leptinotarsa decemlineata) are one of the first invasive insect species to spread across the Earth and have become one of the main agricultural pests thanks to human "help". Spreading across the US and Canada in the late 19th century, these beetles "migrated" with the provisions of the United States Army to France at the end of the First World War, and to Germany after the Great Patriotic War.

The first attempts to destroy these beetles with the help of pesticides ended in failure - the American "invaders", as farmers in the GDR called them, quickly adapted to the poison and became invulnerable to the effects of poisons. Further complicating the problem is that the Colorado potato beetle has no natural enemies outside of the US, making it one of the most dangerous and enduring crop "enemies" on Earth.

Chauville and his colleagues took the first step towards unraveling the success of these beetles by deciphering their DNA and comparing their genome structure with other pests and harmless insects.

As the geneticist notes, his team was interested in two things - how the Colorado potato beetle was able to adapt to life in the harsh climate of Russia and other northern European countries in a very short time, and the secrets of its survival when in contact with new types of insecticides.

Scientists got an answer to the first question - it turned out that the DNA of potato pests contains several dozen genes responsible for the production of a very wide range of enzymes that can digest an extremely diverse range of proteins and sugars. This, according to geneticists, allows the Colorado potato beetle to be practically an "omnivorous" insect, despite its narrow specialization in potatoes and other nightshade plants.

On the other hand, Shoville and his colleagues could not find the genes responsible for the invulnerability of the Colorado beetles - those sections of DNA that are responsible for resisting insecticides have the same structure and size as other insects. As scientists hope, further study of the genome will help them understand exactly how this "superpower" of beetles works.

Nevertheless, geneticists managed to find the "Achilles heel" of the Colorado beetles - it turned out that their cells make extensive use of short RNA molecules to block the action of certain genes, which can be used to create more effective versions of insecticides, to which pests will not adapt as quickly as to DDT and other "Colorado beetle killers" of the past.
