Scientists have received evidence of a cycle of the Earth's magnetic field with a period of 200 million years

2021-08-22 18:12 The results of a new study by the University of Liverpool provide additional evidence for an approximately 200-million-year cycle of the strength of the Earth's magnetic field. Scientists performed thermal and microwave paleomagnetic analysis of rock samples from ancient lava flows in Eastern Scotland to measure the strength of the geomagnetic field at key time periods in the practical absence of previ...

Rattlesnake rattles trick human ears

2021-08-21 21:27 Rattlesnakes increase their rattling rate as potential threats approach, and this abrupt switch to a high-frequency mode makes listeners, including humans, think they're closer than they actually are, researchers report August 19th in the journal Current Biology. "Our data show that the acoustic display of rattlesnakes, which has been interpreted for decades as a simple acoustic warning signal about th...

The Institute of Archeology of the Russian Academy of Sciences has published an electronic archaeological map of Russia

2021-08-20 21:48 The Institute of Archeology of the Russian Academy of Sciences has opened access to the geoinformation system "Archaeological Monuments of Russia" — an electronic map that contains data on more than 42.5 thousand objects. In 2014, a working group led by the Director of the IA RAS Nikolai Makarov began to develop a nationwide electronic archaeological map. An automated information processing system and a da...

Cancer under the control of a magnetic field

2021-08-19 11:44 The non-magnetic coating of silicon oxide magnetic nanoparticles significantly increases the death of cancer cells. This conclusion was reached by Russian scientists as a result of the study. Such a shell does not allow the nanoparticles to combine, as a result, they retain effective magneto-mechanical properties in a low-frequency alternating magnetic field. The study is published in the journal Colloids a...

Spyware: Rights experts push for surveillance technology moratorium

2021-08-18 10:31 A group of UN-appointed experts on Thursday called for a moratorium on the sale of surveillance technology, warning against the danger of allowing the sector to operate as “a human rights-free zone.” Their recommendation comes in the wake of the Pegasus spyware scandal targeting hundreds of journalists, activists and politicians. Violating rights, endangering lives They said until robust regulations o...

The Trade robot uses threaded fins to overcome obstacles

2021-08-17 11:47 When it comes to robots designed to move across rough terrain, there are usually models with tracks or legs. However, the new Tready robot combines the best of both approaches by using four tread "fins". This robot, manufactured by HEBI Robotics, is designed for applications such as search and rescue, industrial control or just exploring the area. "Tready is designed for everyone who is interested in a stro...
