How can dolphins play with whales?

Dolphins and whales are able to play with each other. Scientists have repeatedly observed one of these interactions between bottlenose dolphins and humpback whales: upon finding a whale, the dolphin swam up and took a position above it, drawn by the wave created. After a while, the whale rose up to take a breath, at the same time lifting the dolphin on its nose. At the same time, the whale straightened up into an uncharacteristically vertical position, after which the dolphin slid down its body back into the water as if from a hill.

Where and when was money backed by opium issued?

In 1918, when the flow of money from Russia was interrupted during the Civil War, the authorities of the Semirechensk region of the Turkestan ASSR decided to print their own banknotes. Moreover, this money was secured not by gold, which simply did not exist, but by opium stored in the cellars of the branch of the State Bank of the city of Verny (now Alma-Ata). The issued banknotes were withdrawn from circulation at the end of 1919.

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, ... >>

Biobank for storing living brain samples 15.11.2023

The biobank, containing live samples of brain metastases, represents a breakthrough in cancer research, providing access to valuable data and unique tools to combat this devastating disease. The results of the study have already found practical application in creating individualized approaches to treating patients.

Spanish scientists presented a unique biobank containing living samples of brain tissue from patients with metastases. This biobank, part of the National Network for the Study of Brain Metastases (RENACER), is a valuable resource for research and drug testing. The resulting data will be available for use in global scientific research.

Traditional brain cancer research and drug testing often uses mouse models. However, the search for human samples begins after significant discoveries, and testing them on humans becomes challenging. Obtaining sufficient numbers of human samples is often a long and complex process, requiring adherence to ethical and legal standards and collaboration with various institutions.

The Spanish National Center for Cancer Research (CNIO) offers a solution to this problem by providing a repository for live samples of brain metastases. During metastasis operations at one of RENACER's 18 associated hospitals, patients can voluntarily provide small sections of their brain for inclusion in this biobank.

Living cells in a biobank enable in-depth studies of drug response, creating patient “avatars” to determine optimal treatment. In addition, RENACER used RNA and exosome sequencing to analyze more than 150 brain metastases, and the resulting information was entered into a publicly accessible database.

Manuel Valiente and Eva Ortega-Paino, authors of the study, report that agreements have already been signed to use organotypic cultures from patients as “avatars.” These cultures may serve as potential indicators of drug sensitivity or resistance. Organotypic cultures reproduce certain aspects of the natural physiology and functioning of the body, which require careful processing. After the tissue sample is collected, it is delivered to the biobank within 24 hours under certain temperature conditions (4 to 8 °C). The tissue is then processed into organotypic cultures, separated, and stored for later research.
