Artificial fruit

12.12.2019

Meidan Levy, a graduate of Israel's Bezalel National Academy of Arts, has developed five types of artificial fruits based on cocktails high in vitamins and minerals.

Levy's project was called Neo Fruit. Each of the five fruits of the series differs from the others in shape and taste, but they are made using the same technology. First, Levy 3D prints the fruit shell using transparent cellulose as a material, then proceeds to filling, filling the shell with nutrient liquid. It contains various trace elements necessary for a person. Nutritionists helped the designer to make the right balance of vitamins and minerals.

The taste of artificial fruits does not resemble any natural fruit. Levy created all the fillers using a homemade device that allows him to "extract oils, tastes and smells from almost any substance." This makes it possible to experiment with tastes, appearance and form. For example, one of the Levi fruits is shaped like an open pea with white balls inside. Another fruit looks like several strawberries connected by one frame.

According to Levy, although we live in an era of abundance, natural resources are still finite - especially given the constant population growth. Therefore, he is looking for ways to feed humanity without increasing the area for agriculture.

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, ... >>

Rescuing teenagers from sleep deprivation 11.10.2022

At the beginning of the school year, teenagers can have a hard time getting used to the new schedule. As a result, they will experience a tired day, disrupted rest, mood swings, and trouble concentrating.

Many teenagers, according to representatives of the National Sleep Foundation and the American Academy of Sleep Medicine, sleep less than eight hours. Although the recommended rate for them is eight to nine hours a day. But recently, scientists have discovered how to improve this situation.

A teenager has two important factors. The first is the need to go to bed earlier through the school schedule, the second is the biological changes that occur with the body of a teenager. Rush Medical University experts tried to resolve this conflict with a single intervention. This experiment continued for two weeks.

In order to help teenagers get rid of sleep deprivation, scientists used bright light therapy. Influenced the participants in this way twice in the morning on weekends. It only lasted two hours. The fact is that bright light makes the “internal clock” start working a little earlier. Such a solution should help teenagers fall asleep at the right time for this.

In addition, the subjects received time management tools and were limited in activities that interfere with early sleep. As a result, the experts managed to shift the sleep time of adolescents by 1,5 hours. That is, they woke up 1,5 hours earlier, and their total sleep time increased by about an hour.

At the same time, in those adolescents whose circadian clock was “set” to a later time, these “clocks” eventually shifted by 120 minutes.
