Two physicists discovered special properties of stable atoms with ‘magic numbers’ of protons and neutrons 75 years ago

Posted by in category: particle physics

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable than others. These nuclei had specific numbers of protons or neutrons, or magic numbers, as physicist Eugene Wigner called them.

Planetary defence mission Hera heading for deflected asteroid

Posted by in categories: asteroid/comet impacts, existential risks

ESA’s first planetary defence spacecraft has departed planet Earth. The Hera mission is headed to a unique target among the more than 1.3 million known asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering mysteries associated with its deflection.

By sharpening scientific understanding of the ‘kinetic impact’ technique of asteroid deflection, Hera aims to make Earth safer. The mission is part of a broader ambition to turn terrestrial asteroid impacts into a fully avoidable class of natural disaster.

Developed as part of ESA’s Space Safety programme and sharing technological heritage with the Agency’s Rosetta comet hunter, Hera lifted off on a SpaceX Falcon 9 from Cape Canaveral Space Force Station in Florida, USA, on 7 October at 10:52 local time (16:52 CEST, 14:52 UTC) with its solar arrays deploying about one hour later.

Scientists invent artificial plant that cleans indoor air and generates electricity

Posted by in categories: biological, mobile phones, solar power, sustainability

Scientists have invented an artificial plant that can simultaneously clean indoor air while generating enough electricity to power a smartphone.

A team from Binghamton University in New York created an artificial leaf “for fun” using five biological solar cells and their photosynthetic bacteria, before realising that the device could be used for practical applications.

A proof-of-concept plant with five artificial leaves was capable of generating electricity and oxygen, while removing CO2 at a far more efficient rate than natural plants.
