Drinking hot drinks when it's hot

01.09.2023

In ultra-high temperatures, many people prefer to relieve discomfort with cool drinks. But it turns out that hot drinks can also play an important role in cooling the body, since they help lower body temperature more effectively. This discovery was made by Peter McNaughton, a researcher at King's College London.

“At first glance, it may seem that hot drinks will only increase the feeling of heat. But it is worth remembering that the human body has an amazing ability to maintain a stable body temperature,” the expert sheds light on this aspect.

Experiments have shown that hot drinks activate special receptors in the nervous system, called TRPV1. These receptors send a signal to the body that it needs to cool down. In response to this, the body begins to secrete sweat more actively.

A particularly effective way to cope with the heat is to sweat. In the presence of wind or a fan, sweat evaporates faster, which makes the heat more comfortable to bear. However, in high humidity conditions, the evaporation process becomes less efficient.

Recent research has confirmed that hot drinks do indeed help cool the body, although only for a limited time. In case of high humidity or the need to wear multi-layered clothing, cold drinks should be preferred.

Experts also call for maintaining an optimal level of water balance in the body during the heat. Hot drinks help maintain adequate fluid levels, which allows the body to continue to produce sweat. It is important to drink enough water in extreme heat to prevent dehydration and its associated negative consequences.

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 ... >>

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, ... >>

Liquid laser that does not evaporate in air 14.02.2023

Scientists have created a cheap and easy to manage and use liquid laser.

Physicists at the University of Tsukuba in Japan have developed a tunable laser based on liquid droplets. Unlike previously created drop lasers, the new device does not require special conditions. The technology will help create cheap and flexible devices for optical communication.

For their development, the researchers used the "lotus effect". These plants are known for their ability to clear dust. Through microscopic tubercles on the surface of the leaf, water drops do not escape, but form almost perfect spheres that roll down, capturing dust particles with them.

Scientists have used a similar approach to create liquid droplets that can act like lasers while remaining stable until the moon. They used 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid and mixed it with a dye. The researchers coated the quartz substrate for the "liquid laser" with fluorinated silica nanoparticles to make the surface repel liquids like a lotus leaf.

In a series of experiments, the scientists showed that when a prepared liquid is applied to a treated silicon substrate using a conventional commercial inkjet printer, tiny droplets form near-perfect spheres.

Such drops can remain stable for at least 30 days. The shape and resistance to evaporation allow the droplet to maintain optical resonance when excited by a laser pump source. And you can control the laser by blowing the surface with nitrogen gas: this shifts the laser peaks in the range from 645 to 662 nm, slightly deforming the shape of the droplets.

The researchers note that all modern droplet lasers require special conditions and cannot work in air because the droplets evaporate quickly. The presented development is the first cheap and affordable liquid laser.
