Grasshopper oil

21.10.2015

Eating insects is deeply alien to Europeans. However, five years ago in Holland there were many companies that grow insects for food. They do not offer the consumer crickets or worms, but extract proteins from them, which are used as food additives. The benefit is that insects consume much less food per unit of useful weight and pollute the environment less than the same cows.

What about insect oil? Wageningen University researcher Dr. Daylan Tsomba-Sosa is doing just that. Insect oil is very useful, because it is rich in omega-XNUMX fatty acids, which are not produced in mammals. It is assumed that the oil obtained from it will go into ice cream, pastries or cream.

“Fat extracted from some insects, such as a grasshopper or a shiny lion fly, has a pleasant fruity aroma. But a cockroach smells disgusting, you can’t use its fat for food, but it will be useful for making lubricants. So far, we are working out the technology for obtaining oils and we study their physical and chemical properties. This is the basis for future commercial applications," says the researcher.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Single transistor SRAM cell architecture 18.12.2015

At the International Electron Devices Meeting 2015, Zeno Semiconductor unveiled a bipolar NMOS transistor, which, upon closer examination, turned out to be composed of two open-base transistor structures. It turned out to be a kind of virtual transistor with the ability to work like a two-transistor SRAM cell.

The developer proposes to create energy-efficient single-transistor SRAM cells and productive two-transistor cells from such transistors. In both cases, the area of the SRAM Zeno cell will be several times smaller than the area of \u6b\uXNUMXbthe classic XNUMXT-SRAM. This saves space and energy consumption, including the benefit of reducing leakage.

The cell area of SRAM Zeno in the 28nm process is reported to be 0,025 square meters. µm. A typical 6T-SRAM in this process is 0,127 square meters. µm. Interestingly, the new cell is even smaller than Samsung's 10nm FinFET SRAM with an area of 0,040 square meters. µm.

The developers also report that the reliability of the innovative single-transistor cell will be no worse than the SEU (Single Event Upsets) for 6T-SRAM.
