In which animals is necrophilia a common reproductive strategy?

In the Amazonian frog Rhinella proboscidea, the number of males is 10 times greater than the number of females. During the mating season, males, fighting for females, form large balls, under which females sometimes drown. This fact does not stop some males - instead of fighting for the living, they extract eggs from the bodies of dead females and fertilize them. Biologists have called this unique behavior "functional necrophilia."

 Random interesting fact from the Great Encyclopedia:

How was electricity theft legally assessed 100 years ago?

In 1899, a court in Hannover, Germany, had to decide whether the illegal appropriation of electricity constituted theft or not?

Engineer Genke, who was at the central electric station, secretly charged two small batteries from the owner and sold them. The court did not find him guilty, although it was proved that the accused had stolen electrical energy from someone else's installation.

In its reasoning, the court indicated that one can speak of theft only when the matter concerns the unlawful appropriation of someone else's property, a movable object, but electricity cannot in any case be considered a movable thing, and it cannot even be said whether electric current can be recognized as a "thing".

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 ... >>

Photocells for indoor use 16.03.2021

Scottish scientists have developed organic photovoltaic cells that turn indoor light into electricity. The new technology was proposed by scientists from the University of Strathclyde and the University of St. Andrews.

Scientists have designed and manufactured organic photovoltaic cells from plastic-like materials similar to those used in smartphone OLED displays. The result is photocells that allow stable and efficient conversion of indoor light into electricity.

The new solar panel captures light energy and simultaneously provides high-speed visible light communication (VLC) using a MIMO technique that increases the channel bandwidth.

Four photocells made of plastic-like materials were combined into a panel, during the experiments it demonstrated the ability to provide wireless optical communication at a speed of 363 Mbps, while simultaneously producing 11 MWh of electricity. An array of four laser diodes was used as a source of information, each of which transmitted a separate signal.

Organic solar cells show maximum efficiency when operating in the typical indoor light from LED lamps. Such solar panels are easy to manufacture, cost less than inorganic counterparts, and can be flexible, making them easy to integrate into mobile devices.

Further development of organic photovoltaic cells capable of receiving information in the future will make it possible to use entire walls of premises at the same time as a communication channel that supports speeds up to 1 gigabit per second, and as a solar panel that provides electricity to network equipment.

Devices that can independently produce energy and transmit data will allow you to connect a large number of gadgets to the Internet and the power grid. Now in the world there are more than 18 billion mobile devices connected to global networks, and in the next 10 years, given the rapid development of the Internet of things, their number will increase to tens of billions.
