Chemical elements for electronic devices have been added to a "vulnerable list"

A vulnerable list of items used in everyday gadgets was created by scientists. Some materials commonly used in cell phones and other devices have been classified as a "serious threat". These include gallium, arsenic, yttrium and silver. Scientists have developed a periodic table that highlights the scarcity of the 90 natural elements, with around 30 being used in cell phones. …

How hot are atoms in the shockwave of an exploding star?

An international team of researchers combined observations of the nearby supernova SN1987A, created with NASA's Chandra X-ray Observatory, with simulations to measure the temperature in shock waves produced by the explosive death of a star. This image overlays synthetic X-ray data on a density map with the simulation of SN1987A. Photo credits: Marco Miceli, Dipartimento di Fisica and Chimica, Università …

I see you: First, the Israeli-French team finds neurons that react to all faces

According to a recent study by Israeli and French researchers, it was possible for the first time to identify neurons in the human visual cortex that can selectively respond to faces. "There has been a lot of research on humans," said Vadim Axelrod, head of the Consciousness and Cognition Laboratory in the multidisciplinary brain research center Gonda (goldsmith) of Bar …

The mysterious Planet Nine hiding behind Neptune may not be a planet at all

Artist's concept for Planet Nine. Caltech / R. Injured (IPAC) Beyond Neptune, something strange happens to the orbits of a series of space rocks orbiting the Sun. Scientists believed that something could only be described by the presence of a giant planet – the so-called "Planet Nine". Astronomers have been baffled for years and now there is another candidate for …

Even the big blue hole of Belize, the largest hole in the world, is not safe from plastic pollution

Richard Branson, Fabien Cousteau and Erika Bergman found plastic soil on the bottom of the Great Blue Hole. The crew found plastic bottles at the deepest point of the sinkhole. Branson hopes that the Fund will increase awareness of the protection of the ocean and its response to climate change. Already in early December, Richard Branson and Fabien Cousteau took …

Greenland ice melts faster than before, according to the study

The results could have serious consequences for the low-lying islands and coastal cities of the planet. Eight of the world's ten largest cities are located near coastal areas and 40% to 50% of the world's population live in areas exposed to rising seas. Michael Bevis, a professor of geodynamics at Ohio State University and lead author of the study, has …

Scientists have finally determined how long Saturn's days are – BGR

Determining the length of a single day on a planet is usually pretty straightforward. You simply pick a landmark and wait for it to reach exactly the same point in its turn twice, and you have your answer. For astronomers studying Saturn, it's not nearly as easy. Saturn does not have well-visible landmarks to trace, and its bubbly atmosphere does …

Protective "cocoons" could block deadly stellar gamma-ray outbreaks

Extinction Event Sometimes, when a gigantic star reaches the end of its life, its inner core begins to collapse and a catastrophic force of energy known as the Gamma Ray Burst (GRB) breaks out. Together with the accompanying supernova they can burn brighter than an entire galaxy – some scientists have suggested that an extinction may occur when the earth …
