A mouse embryo is grown in space

30.10.2023

Aboard the International Space Station, scientists carried out a unique experiment by cultivating and growing mouse embryos in microgravity conditions. Molecular biologist Teruhiko Wakayama of Yamanashi University led the project, which could provide important data on the effects of the space environment on embryo development.

The results of the experiment confirmed that at the initial stages of development, mouse embryos are able to survive in microgravity conditions. This is important given plans for long-term space missions, such as missions to Mars, where pregnancy may become a reality during extended space travel.

The astronauts spent four days culturing the embryos, preserving them in paraformaldehyde for later analysis on Earth. Despite the lower survival rate compared to artificial and ground gravity conditions, the survival of embryos in microgravity opens up prospects for further research and preparation for future space missions.

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, ... >>

Octospot - action camera for diving enthusiasts 20.07.2016

The Kickstarter website is raising funds for the Octospot wearable camera. This action camera is aimed at diving enthusiasts.

The developers emphasize the reliability and simplicity of the camera. With an aluminum and polycarbonate body, the device can withstand diving to a depth of 200 m, and all control is carried out by only two controls. Of course, they are designed to be handled with gloves.

The camera is equipped with a pressure sensor, the readings of which are stored simultaneously with the video and are used to correct the white balance. This makes it easy to know at what depth any moment of the video was taken.

The Octospot camera allows you to shoot 4K video at 30 fps. By reducing the resolution to Full HD, you can increase the frame rate up to 100 fps, and at HD resolution, the frame rate can be increased to 240 fps. When played back at a slower frequency, this makes it possible to obtain a slow motion effect. You can also take 12MP photos. Recorded footage can be stored on microSD cards up to 64 GB.

Without recharging the battery, you can shoot up to two hours in a row. The battery status, as well as some other data, is displayed on a small OLED screen at the end of the camera. Device dimensions - 112 x 34 x 34 mm, weight - 161 g.

The first fundraisers could secure the right to receive a camera for $349. Shipment of orders should begin in January 2017.
