Pulsars are rotating neutron stars that, like lighthouses, emit beams of electromagnetic radiation. The fastest spinning pulsars with a spin period of less than 30 milliseconds are known as millisecond pulsars (MSPs). It is assumed that they form in binary systems, with the neutron star spinning up due to the accretion of matter from the … Read more
Scientists at Curtin University in Australia discovered rare dust left behind from a supernova explosion inside a meteorite. The discovery is reported in the article, published в The Astrophysical Journal. Researchers used a technique called atom probe tomography to analyze dust particles inside a sample of the ALH 77307 meteorite discovered in Antarctica. This carbonaceous … Read more
The attack, called GoFetch, targets the hardware data prefetch (DPM) optimization feature. The researchers explained that DMP helps the processor guess what data it might need in the future. Experts said that hackers can fraudulently obtain certain information related to encryption. The problem was discovered in Apple computers based on proprietary processors, which the corporation … Read more
Textbooks say there are two main groups of amphibians. They are not lying, anurans, those without tails (frogs, toads…) and caudates, with tails (salamanders and newts) represent the majority of this class of animals. But there is a third order, that of the gymnofiones, or caecilians, which live in humid equatorial and subtropical areas. The … Read more
They didn’t know what they had. The caretakers of a family museum in Verona (Italy) believed that the strange object was fake. But a historian from the University of Cambridge (United Kingdom), Federica Gigante, knew what it was as soon as she saw it in an image uploaded to the internet. As soon as she … Read more
The skin is the largest organ in the human body. A man’s can occupy two square meters, weigh up to five kilograms and be as thick as a centimeter, on the soles of the feet, or as thin as 0.5 millimeters, in the testicular sacs. It is the interface with which humans relate to the … Read more
The human being has at his service the most loyal and efficient defensive army: the immune system, an intricate network of cells, tissues and organs that tirelessly protect the body from external threats. And although they are good at what they do, mercilessly detecting and annihilating harmful elements, they are not indefectible. Sometimes, they fail. … Read more
After the Big Bang, everything happened very quickly. An international team of astronomers has just published, in the journal Nature, the discovery of the oldest known black hole and it was already there more than 13 billion years ago, just 400 million years after the explosion. In such a short time (on the cosmic scale) … Read more
