What type of dinosaurs were cold-blooded or warm-blooded?

The body temperature of dinosaurs was 36-38 ° C, that is, about the same as that of modern mammals. This conclusion was made by paleontologists on the basis of an analysis of the tooth enamel of fossil pangolins, namely, by the content and interconnections of heavy oxygen isotopes in it. Thus, dinosaurs had a body temperature higher than the ambient temperature, unlike modern cold-blooded ones. But to argue that dinosaurs were real warm-blooded is also premature.

Random interesting fact from the Great Encyclopedia:

What primarily determines a person's optimism or pessimism?

An optimistic or pessimistic view of the world of each individual person is programmed genetically. According to research by scientists from the University of Michigan, it is determined by the concentration of neuropeptides Y in the brain: a reduced concentration makes one perceive the environment pessimistically and depressively.

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 ... >>

Rearview Mirror with Android 20.01.2014

Pioneer, a Japanese auto electronics manufacturer, and Robin Labs, which develops a voice assistance system based on Yahoo! services, demonstrated a "smart" rear-view mirror. One of the features of the novelty is that the device has a pre-installed Android operating system. The demonstration of the device, which was called Drive Agent Mirror, took place during the CES 2014 exhibition, held in January this year in Las Vegas.

The device is somewhat longer and wider than a conventional car interior mirror. On its left side is a small touch screen that merges with the remaining mirror part when turned off and can be used to view the road behind the car.

At the same time, in the active mode, Drive Agent Mirror can act as an infotainment system, navigator and voice-controlled digital assistant. On the basis of voice commands, the calculation of the time for movement within the laid route, the formation of the most optimal path, taking into account road conditions, etc., are performed. Speech recognition is carried out using Robin Labs technology. According to unconfirmed information, this company is developing a Siri competitor for Yahoo!

Pioneer believes that because drivers are constantly looking in the rear-view mirror to monitor the traffic behind the car, navigation and entertainment functions in the interior mirror are much more convenient than, for example, on the head unit located on the center console. The developers believe that Drive Agent Mirror distracts the driver from driving to a lesser extent.

So far, only a prototype of a saloon mirror with Android OS has been demonstrated. When the device will appear in free sale, and how much it will cost, is not reported.

It is worth noting that several automakers have already thought about using the Android OS in auto electronics. As previously reported in the media, Kia Soul and Hyundai Genesis cars by the end of 2013 should receive multimedia systems running Google's mobile OS. Google Corporation recently announced the creation of the "Open Automobile Alliance", which will integrate mobile technologies based on Android into automotive systems. The alliance included Honda Motor, Audi, Hyundai Motor, General Motors, and GPU maker Nvidia.
