Variables of nature

Within physics there are certain physical quantities that play a central role. These are things such as the mass of an electron, or the speed of light, or the universal constant of gravity. We aren't sure why these constants ...

Neural network-based forecasting for renewable energy transmission

Everything was simpler in the past. Power plants were distributed throughout countries and their output was adjusted according to energy demand. Power plants used calendars and weather forecasts, among other means, to predict ...

Ground surveying digs deep for Batavia secrets

A group of WA researchers are hopeful they will find remains from the wreck of the infamous Dutch ship Batavia following the discovery of a tooth last year on Beacon Island off the Mid West coast.

Gene sequencing refines threatening parasite list

Twenty-six species of Cryptosporidium have been recognised and 18 species declared non-valid in a recent shake-up of the parasite's taxonomy using DNA sequencing techniques.

Tests confirm nickel-78 is a 'doubly magic' isotope

The stability of atoms can vary considerably from one element to the next, and also between isotopes of the same element (whose nuclei contain the same number of protons but different numbers of neutrons). While many isotopes ...

Video: Sprites, gravity waves and airglow

Look! Fast! Sprite lightning occurs only at high altitudes above thunderstorms, only last for a thousandth of a second and emit light in the red portion of the visible spectrum, so they are really difficult to see. But one ...

Loudspeakers in jet engines

Unless one is attending an aeronautics convention or going on a trip, noise associated with aircraft engines is rarely tolerable. Different means of significantly reducing that noise are being tested by EPFL's Electromagnetics ...
