Can dogs diagnose cancer early and how?

Dogs can diagnose various forms of cancer at an early stage. Japanese scientists proved this by training a female Labrador for this purpose. Despite the fact that the task was complicated by the presence of benign tumors or diseases of the intestine in some of the tested patients, the dog was 95% successful in detecting cancer from breath samples and 98% from stool samples. This confirmed the hypothesis of doctors that cancer changes the smell of the body, although it is not yet clear which chemical compounds are responsible for this. Having identified them, it will be possible to create an "electronic nose" for diagnosing this disease, since the use of dogs, although effective, is ultimately very expensive.

 Random interesting fact from the Great Encyclopedia:

How cold is the universe?

A little more than three degrees above absolute zero, i.e. approximately -270 ° C. Below absolute zero (0 K), there is no temperature; at such a temperature, theoretically, the thermal movement of molecules, atoms, etc. should stop.

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, ... >>

Improving OLED Performance 15.02.2024

Scientists from Durham University have presented an innovative method to improve the performance of blue organic light-emitting diodes (OLEDs). This breakthrough not only promises brighter displays, but also increased stability and energy efficiency of electronic devices. OLED displays have found widespread use in modern technologies, improving image quality on smartphones, TVs and other devices. However, achieving stable and efficient blue light emission in OLED technology has long remained a challenge.

Now experts have found a solution that could open up new horizons in creating next-generation energy-saving displays. A new design strategy using hyperfluorescent OLEDs (HF), developed by a team led by Kleitos Stavre and Professor Andrew Monkman, played a key role in this.

The new research has the potential to change the landscape of the electronics industry, providing brighter, more energy-efficient displays for a wide range of devices - from smartphones to TVs and wearables. Commercialization of HF OLED could be the next step in the evolution of electronics, providing consumers with higher picture quality and lower energy costs.

Hyperfluorescent OLEDs utilize a unique mechanism for transferring energy from the sensitizer molecule to the individual emitter molecule, significantly improving efficiency and stability. It turns out that certain sensitizer molecules, previously not considered due to their poor emission properties, can significantly improve OLED efficiency when used in hyperfluorescent OLEDs. One such molecule is ACRSA, which can triple the efficiency of OLEDs due to its rigid molecular structure and long-lasting excited states.

"We have identified blind spots where materials not traditionally considered can be highly effective as sensitizers in hyperfluorescent OLEDs," explained lead study author Kleitos Stavrou. Additionally, the team demonstrated that using a greenish sensitizer such as ACRSA can achieve deep blue light emission by transferring energy to the blue terminal emitter. This approach improves the stability and durability of blue OLED displays and reduces exciton energy, resulting in more energy-efficient displays.

"Our results open up new possibilities for hyperfluorescent OLEDs, which could significantly expand the choice of materials for the next generation of displays, using up to 30% less power," said Professor Andrew Monkman.

The potential applications of this discovery are very wide - from smartphones and TVs to wearable devices and beyond. With further development and collaboration with industrial partners, the researchers aim to commercialize HF OLED. The new research marks an important step in the development of brighter, more stable and energy-efficient blue OLED displays.
