Extra-Ordinary Heat Wave | Open Mind

The heatwave which invaded England recently was no ordinary one. At numerous locations the temperature exceeded 40°C (104°F) which, as far as we know, has never happened before in the British Isles. England definitely isn’t prepared for such temperatures, as Melissa Harrison makes abundantly clear in the Washington Post; an airport closed when the runway … Read more

Manufacturers and raw material suppliers from different locations are trying to become a part of this … Read more

Gravitational wave radar could probe deep space for tiny stellar objects | Science

Theoretical physicists have hit on a new way to test Albert Einstein’s theory of gravity, or general relativity, and — just maybe — probe the distant universe for tiny, hard to detect objects. Gravitational waves — ripples in space set off when massive objects such as black holes whirl together and collide — should bounce … Read more

Physicists Say They’ve Built an Atom Laser That Can Run ‘Forever’

A new breakthrough has allowed physicists to create a beam of atoms that behaves the same way as a laser, and that can theoretically stay on “forever”. This might finally mean the technology is on its way to practical application, although significant limitations still apply. Nevertheless, this is a huge step forward for what is … Read more

Giant galaxy cluster collision triggers vast shock wave

Two giant galaxy clusters crashing into each other triggered enormous shock waves stretching 1.6 million light-years through space. The findings, revealed by NASA’s Chandra X-ray Observatoryare helping astronomers better understand the powerful processes at work in collisions between clusters of thousands of galaxies. Galaxies make up only a small percentage of the total mass of … Read more

Astrophysicists Predict Gravitational Wave Strength From Merging Supermassive Black Holes

An artist’s impression of two black holes about to collide and merge. Gravitational waves are ripples in the curvature of spacetime caused by accelerated masses that propagate as waves at the speed of light outward from their source. Although you do not need a gigantic object to create gravitation waves, our instruments are only able … Read more

Completely New Type of Magnetic Wave Discovered Sweeping Across Earth’s Outer Core

Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding opens a new window into a world we can never see. This mysterious wave oscillates every seven years and propagates westward at … Read more

New type of magnetic wave discovered in Earth’s core

Scientists have detected a completely new type of magnetic wave that surges through Earth‘s outer core every seven years, warping the strength of our planet’s magnetic field in the process. The waves – dubbed “Magneto-Coriolis” waves because they move along the Earth’s axis of rotation, per the Coriolis effect – creep from East to West … Read more

Wave Mixing Laser- and X-Ray-Beams

Two light beams from flashlights will not be influenced by each other when they cross. This is different for very intense laser pulses which meet in a suitable “nonlinear material” – here, beams can be deflected and new beams of different color can be created in a process called wave-mixing. The observation of such wave-mixing … Read more
