Headphones JBL LIVE Pro 2, LIVE Free 2 and Reflect Aero

12.01.2022

JBL introduced the LIVE Pro 2, LIVE Free 2 and Reflect Aero wireless headphones. All three new items have active noise cancellation.

Also, all three models received support for touch control, Google Assistant and Alexa. You can set up your headphones through the JBL Headphones app.

JBL LIVE Pro 2 features 6,8mm drivers and six microphones. The novelty is aimed at fans of sports. She received IP68 water protection and can work without recharging up to 8 hours (a day with a case).

JBL LIVE Free 2 received 10mm drivers. Headphones were awarded the CES Innovation Awards. The model received IPX5 protection and works 7 hours without recharging. The case extends autonomy five times.

JBL Reflect Aero got 11mm emitters and a matte body (case too). Water protection meets the IPX5 standard. A full battery charge in independent modules is enough for 10 hours of music playback. The novelty received support for fast charging. 15 minutes of "refueling" is enough for 4 hours of work. Including the case, the headphones can play music for 40 hours.

The JBL LIVE Pro 2, LIVE Free 2 and Reflect Aero are each around $150. Sales will start in April 2022.

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, ... >>

The largest X-ray laser gun is launched 31.08.2017

The European X-ray Free Electron Laser (XFEL), a new X-ray free electron laser, will start operating this month and, when brought to full power, will be capable of delivering 27 pulses per second, 200 times more than the world's fastest laser. today's X-ray laser located in California, USA.

The XFEL laser will not be used to strike the enemy or to shoot at dangerous asteroids, it will be used exclusively for scientific purposes as an ultra-high-speed X-ray camera that provides the highest image resolution.

The €1.5 billion X-ray laser XFEL will be the successor to the FLASH laser located in Germany. The XFEL laser is a linear accelerator with 2.1 resonators in a 768-kilometer tube, each with unique shapes and magnetic field parameters. Electrons oscillating in this field at the moment of changing the direction of motion emit photons of light, which are sent to the next resonator. Passing through a series of resonators, the energy of light photons increases, and their frequency shifts to the X-ray range.

The high-energy and short X-ray pulses of the XFEL laser will be used to capture detailed images of living cells and their protein molecules with atomic resolution. Also, the high speed of the XFEL laser will allow shooting fast phenomena and processes, such as the formation of chemical bonds.

There are currently a number of X-ray lasers in the world, but none of them can compete with the XFEL laser. For example, a Stanford University laser is capable of generating 120 pulses per second, while a similar laser in Japan has a speed of 60 pulses per second.

Two more X-ray lasers will soon be launched, one in Switzerland and the other in South Korea. But these new lasers will also be inferior in all respects to the new XFEL laser. Nevertheless, the XFEL X-ray laser is not destined to be on the “pedestal of honor” for very long. It will be dislodged from there by a new laser at Stanford University's SLAC National Linear Accelerator Laboratory, which will pulse at a rate of one million times per second and will be operational in 2020.
