What explains the existence of butterflies, in which wing patterns are completely different?

An organism that contains both male and female characteristics due to a developmental anomaly is called a gynandromorph. The manifestation of such an anomaly is especially noticeable in species with pronounced sexual dimorphism, that is, noticeable external differences between males and females. For example, in a gynandromorph butterfly, one wing looks like a typical male, and the other looks like a typical female.

 Random interesting fact from the Great Encyclopedia:

What type of communication do adult cats use only to attract a human?

Adult domestic cats do not meow when communicating with each other. The sound "meow" is typical for kittens calling their mother, and adult cats have learned to use this sound to attract a person. For adult wild cats, meowing is generally not typical in any situations.

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 ... >>

Tea won't overflow 25.06.2002

D. Kumar from London has designed a teapot in which, thanks to the special shape of the spout, spilling of tea is completely excluded.

At a distance of about 1 cm from the end of the spout, there is a groove that narrows the jet and accelerates the flow of tea. When the teapot returns to the upright position, the teapot deflection jerk impulse action acts as a barrier to the tea and it does not spill.

Such a design of the spout can be widely used not only in kettles, but also in pistols for pouring gasoline into a gas tank, making the process of refueling cars more fireproof.
