Waves Discovered in Solar Corona

Scientists for the first time have observed elusive oscillations in the suns corona, known as Alfvén waves, that transport energy outward from the surface of the sun.

Alfvén waves are fast-moving perturbations that emanate outward from the sun along the pathways of magnetic fields, transporting electrodynamic energy. Although they had been detected beyond the sun, they had never before been viewed within the corona, the outermost layer of the suns atmosphere.

By tracking the speed and direction of the waves, researchers will be able to infer basic properties of the solar atmosphere, such as the density and direction of magnetic fields. The waves may provide answers to questions that have puzzled physicists for generations, such as why the suns corona is hundreds of times hotter than the surface.

Holy Periodic Fission, Batman!

Bad Science » Pink, pink, pink, pink. Pink moan.

This week every single newspaper in the world lapped up the story that scientists have cracked the pink problem. “At last, science discovers why blue is for boys but girls really do prefer pink” said the Times. And so on.
The study took 208 people in their twenties and asked them to choose their favourite colours between two options, repeatedly, and then graphed their overall preferences. It found overlapping curves, with a significant tendency for men to prefer blue, and female subjects showing a preference for redder, pinker tones. This, the authors speculated (to international excitement and approval) may be because men go out hunting, but women need to be good at interpreting flushed emotional faces, and identifying berries whilst out gathering.

Mainstream media science reporting is terrible.

A habanero pepper rates at between 200-300k scoville units which means they are really friggin hot. This dude took a big bit of one and the heat from the pepper really kick his ass.

YouTube - Biogas Wood Stove Demonstration

This stove is a partial oxidation gas generator stove. It produces Hydrogen, Carbon Monoxide, Methane and other cracked organic compounds. The same principle is in our books on gasification of wood for engines and cars. Yes, you CAN run a car off this type of system and over 1 million vehicles did this during WWII… it can still work today

This is just one demonstration out several. A hydrogen-crazy group of chemists are putting together a fascinating series of publications, research, and experiments. This technology is about a century old, but was perhaps ahead of its time.
