What animals are studied by German biologists as part of the Angelina Jolie Project?

In several isolated lakes in Africa and America, cichlid species have been observed in which two populations have emerged in the course of parallel evolution: thin-lipped and thick-lipped. Fish with thick lips have adapted to extract food from the crevices of stones, enveloping them with their lips and sucking prey. Thin-lipped cichlids usually search for prey in open water. In the volcanic Lake Apoeque, in Nicaragua, cichlids appeared a little more than a hundred years ago from the nearby Lake Managua, but during this time they managed to separate on their own based on the thickness of their lips. Axel Meier of the University of Konstanz in Germany, who studies evolutionary changes in these fish with colleagues, jokingly calls the research program the "Angelina Jolie Project."

Random interesting fact from the Great Encyclopedia:

Where do fish live that like to walk on the bottom instead of swimming?

In 2010, new species of anglerfish were found off the coast of Australia. Instead of swimming, these fish prefer to “walk” along the bottom, moving their pectoral fins, which look like animal paws.

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 ... >>

Cold computer memory 27.12.2012

Researchers at the University of California School of Engineering and Applied Sciences have made significant improvements, significantly advancing the ultra-fast, high-bandwidth computer memory class. This type is called magnetoresistive random access memory or MRAM.

The team called their new development MeRAM. It has great potential for use in almost all electronic devices - smartphones, tablets, computers, microprocessors. You can also use it to store data. MeRAM's key advantage over other technologies is its combination of low power consumption, high read and write speeds, and non-volatility - the ability to retain data in the event of a sudden power outage.

Currently, magnetic memory is made on the basis of technology using the spin of electrons, and not just their charges. This technology (SST) uses electrical current to write data to memory. It outperforms other technologies in many ways, but it requires a certain amount of power, and quite a lot of it, and therefore generates heat when recording. In addition, the volume of such memory is limited by the currents required to record information per unit area.

In the case of MeRAM, the scientists replaced current, which plays a key role in SST, with voltage. This eliminates the need to transfer huge amounts of electrons through wires, and instead uses electrical potential differences to switch magnetic bits and record information. As a result, the computer generates much less heat, making it up to 1000 times more energy efficient. And the memory itself can be 5 times denser - more information is stored in the same physical area, which reduces the cost of transferring a bit.

"The ability to switch nanosized magnets using voltage is an important and rapidly growing area of research in magnetism," said electrical scientist Pedram Khalili, project leader at UCLA. how the devices will operate without the need for an external magnetic field and how to integrate them into high-density memory arrays".
