scientists have long speculated that sleet helps restore and repair the brain now researchers studying

myself found evidence that the story bro spinal fluid that washes through the brain flushes

out potentially harmful proteins

when the mice or sleeping clean out happens twice as fast as when they're away

for a hundred years scientists have been trying to nail down where cosmic rays come

from twenty thirteen be fairly gamma ray space telescope

finally spotted solid evidence the race which actually high energy particles

originate inside the roman mask exploding stars

when viruses attack bacteria the bacteria flight back and that defences inspired a remarkable gene

editing technique how crisper it'll outsiders to use approach to perform micro surgery on genes

with astounding precision

receiver could help naval who genetic engineering research

while just call them we're gonna weights minute sure organs grown in the lap

that used to be science fiction but this year researchers using stem cells grew mini

kidney liver buttons and even rudimentary brains the size of an apple c

there's a humbling plot most of the cells and the nn your body don't belong

to they belong to bacteria that live inside of twenty thirteen researchers made important progress

toward figuring out how these microbes

and there might help physicians treat malnutrition cancer and other disease

ros kites are materials that could make solar power cell cheaper easier to make and

very good at converting sunlight into electricity but they're not up there yet with commercial

silicon solar cells still there cleaning fast

how higher is called r s v sense millions of babies to the hospital every

year now researchers have used structural biology to the engineering or sp protein to trigger

an immune response

it's a pioneering accomplishment and a big step toward creating a vaccine

after more than a decade of failure researchers this euronounce that they had finally derive

stem cells from cloned human embryo recipe for making them included action caffeine stem cells

can develop and any type of cell in the body and that could help assigned

to study and treat diseases

now here's a concept c through brain sciences this year learn to make brain tissue

as clear as glass

right chemically removing fatty look at scatter light

researchers open the window on the hidden structures inside

and now for this year's break through a whole new way to treat cancer answering

in the therapy text tumours by harnessing a person's "'em" use just this year is

a promising results from clinical trials researchers successfully treated a number of different types of

cancers but this is very much your work in progress

it only helped a handful patients and there's still a lot to learn about how

this therapy works
