What is a diatom?

Diatoms are tiny single-celled plants. They exist by the billions in all the waters of the Earth. The largest of them are barely visible to the naked eye, and the smallest are 0,025 millimeters long. Although they are so tiny, each of them builds a stone shelter for herself, as hard as granite. There are over 10 species of diatoms. They have a variety of shapes. Their dwelling consists of two shells, one above the other, like the top and bottom of a box. They are connected by edges, as if connected by belts. Inside is a living plant.

Most diatoms float in water or attach themselves with a jelly-like substance to rocks or larger plants. Some can safely swim in the water from place to place, but how they move independently is unknown. Diatoms usually reproduce by fission. The cell inside the box divides, the box is divided in two. Each of the halves begins to live an independent life, build a new home.

Diatoms are very important in our life. Together with some others, they are the main plant organisms of the ocean. When alive, they change the mineral substances dissolved in water into organic substances, they are also a source of food for other living organisms living in the wild, including fish and whales. The oil they produce accumulates in the liver of the fish, from where it is industrially extracted. It is very rich in vitamins.

Biofuels - good or bad?

Biofuel is an alcohol obtained from plants - cane, corn, rapeseed, etc. Gasoline is saved, which is good. Emissions of harmful substances are reduced - that's great. But crops are used to produce biofuels, leaving less acreage for food production, which is already in short supply in the world.

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 ... >>

There is no star formation at the center of the Milky Way 12.08.2016

Astronomers from Japan, South Africa and Italy have discovered that there are no young stars in the vast region around the center of our galaxy. This unexpected result may lead to a revision of views on the evolution of the Milky Way.

Scientists have been looking in the inner region of the Milky Way for classical Cepheids, which are young stars with an age of 10 to 300 million years. (Recall that our Sun is about 4,6 billion years old.) This is quite a challenge, because the Galaxy is full of interstellar dust, which prevents many stars from being seen and affects the apparent luminosity of those that are visible. The researchers compensated for this with near-infrared observations. They worked at the Japanese-South African telescope in Sutherland (South Africa), a place known for having the cleanest and darkest nights in the world.

Astronomers have discovered almost 30 Cepheids and were surprised to find that there is not a single one within an 8000 light-year radius around the center of the Galaxy. The exception is a small region in the very center of the Galaxy with a radius of 150 light years, where four Cepheids were discovered even earlier. If there are no young stars in this vast region of the inner disk of the Galaxy, then there has been no significant star formation there for hundreds of millions of years. For comparison, the diameter of our Galaxy is about 100 light years, and the Sun is located at a distance of 000 light years from its center.

This result is consistent with recent studies by radio astronomers, but contradicts one work with similar measurements. However, the authors of this study believe that there was an error in determining the distance due to reddening of the radiation when passing through interstellar dust.
