Tiru zena – malaria, liter of light,

Some news stories are too good to read and move away from.

Vaccine for malaria

There’s a promising work towards a vaccine for malaria. Interesting things about it:

– It’s a vaccine for malaria, a disease responsible for 2.23% of deaths worldwide

– It’s based on the fact that some people have developed immunity from malaria

– It can be produced cheaply if it proves successful.

Liter of Light

This one is a very cool innovation to light poorly lit houses. Take a bottle of water, drill a hole in the roof and stick the bottle in. The key thing is the water refracts the sunlight whereas if you simply leave a hole in the roof what you get is a long line of light which doesn’t help much. A little bit of work to keep the roof sealed to avoid rain water from coming through and it’s all set. More on Liter of Light website.

    next question: how is it that a neutrino could travel faster than light? does it have anything to do with solenoids?

    the refracted light is thought to mess with their compound eyes.

      i don’t know…. from a religious point of view anything is possible. and science…if a getere sees a blue car he could conclude all cars are blue. that’s what it is.

    i didn’t know that. is it the light that repels them? mosquitoes tend to like light bulbs.

    refraction is not the opposite of reflection. when light enters a certain medium its original path may change. reflection and refraction are used to describe this change. reflection is for bouncy effects and refraction for bendy ones.

    a plastic bag of water can be used to repel flies using the same principles.the same principles -that is a bold statement coming from someone with my track record on physics. is refraction the opposite of reflection?🙂
