Hearing restoration with butterflies

05.11.2022

A team of Australian researchers from Melbourne and Perth has developed an innovative device to repair the eardrums in patients with hearing impairments.

Scientists have added silk to a ClearDrum middle ear implant that can grow a patient's cells. The implant looks like a contact lens from the outside. Silk, which easily changes shape, is ideal for the device, experts said.

The researchers removed sericin, a protein found in silk, also known as silk glue. Then the protein was heated to a liquid state and used to create a device.

The device must be surgically placed under the damaged eardrum. Subsequently, it becomes a platform for the growth of new tissue. If the damage is small, the device will dissolve some time after repair. With serious damage, it remains in the ear forever.

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, ... >>

Emotions of the West and East 10.02.2008

American and Japanese psychologists, studying differences in the expression of emotions in the two peoples, handed out photographs of faces to Japanese and Americans and asked them to rate whether the photographed person had a cheerful or sad expression. And the photographs were "synthetic": sad eyes were mounted with a wide smile, or, conversely, the eyes were smiling, and the tips of the lips were lowered.

The results of a survey of 120 people showed that when evaluating facial expressions, Americans look primarily at the mouth, while Japanese look almost exclusively at the eyes. Scientists have concluded that the Japanese traditionally restrain their feelings, their facial expressions are inactive, so you have to look at the eyes, the expression of which is more difficult to control than the expression of the mouth.

By the way, Japanese emoticons, computer icons synthesized from the characters of a conventional keyboard, are very different from Western ones. Where we put :-) to communicate his cheerful mood, the Japanese draws (^ ^). The sad mood icon in the everyday life of our computer users looks like :-(, and the corresponding Japanese one looks like (; _;) (tears drip from the eyes). That is, in our version, when the mood changes, the mouth pattern changes, and in Japanese - the eye.

Examples of Japanese emoticons: (^_^) - smile, joy, (^^) - sometimes a smile, sometimes something like "hee hee", a slight smile, (^.^) - a woman's smile, (^_^;) - nervous laughter, (^o^) - dying with laughter, \(^_^)/ - joy, (*_*) - admiration, (^L^) - happy, (^(^) - happy, (^_ ^)/ - greeting waving hand, (^_^)/~~ - greeting, (;_;)/~~ - waving goodbye, (-_-) - sour mine, sadness, sadness, mysterious smile, ( ^_~) - wink, (^_-) - wink, (o_o) - surprised, (O_O) - very surprised, (o_O) - bewilderment, surprise, (V_v) - unpleasant surprise, (> _>) - skepticism , (@_@) - awesomeness, (*^o^*) - excited, (*^.^*) - excited, (v_v) - sadness, (;_;) - tears, crying, (T_T) - tears , crying, (~~>.<~~) - tears, crying, ///_^ - emo, ^_\\\ - emo, (*^^*) - embarrassment, shame, (^_^;;; ;) - embarrassment (in a cold sweat), (^^') - what is shown in anime and manga with a drop (embarrassment), (^^;) - a variation on the theme of a drop, (>_< ) - angry, angry, (>.< ) - angry, angry, m(._.)m - apologizes, (?_?) -misunderstanding, confusion, question, (!_!) - shock, (^o^;> - "I'm sorry, I didn't understand", (-_-;) - illness, (-_-;)~ - illness, (x_x) - death, corpse, (+_+) - death, (+_+)~ - death, (%_%) - after a night at the computer, ^}{^ - love, (=__=) - sleepy or "tired :", (-.-)Zzz.. - sleep, (u_u) - sleep, (* ^)3(*^^*) - kiss, \=oo=/ - wear glasses, m(_)m - humble a bow of gratitude or apology, (=^_^=) - a cat, (=^.^=) - the same, (^..^) - a pig, ("\ (o_O) /") - Father Medved, Y ( O,,,,O)Y - Cthulhu, (x(x_(x_x(O_o)x_x)_x)x) - alive among zombies.

If in Western emoticons the strength of emotions is expressed by the number of brackets)))))))))))))))))))))))))))))))))))))))), then in in "Japanese-style" emoticons, this can be expressed by the length of the underline: ^______________^.
