I’ve been watching youtube movies from the khanacademy user I find them great
I’ve seen mostly financial clips related to banks, mortage crisis but he also has interesting clips on physics and mathematics

is the doomsday coming?
some scientists think so…
they are so sure it is true, that they have filled a lawsuit in Hawaii’s U.S. District Court against U.S. Department of Energy, Fermilab, the National Science Foundation and CERN
they want them to postpone their experiments with coliding high energy particles while the safety was reassessed
those people are former nuclear safety officer Walter Wagner and Luis Sancho
the thing is, those scientist think that those organizations, can, by experimenting, spell the end of us all
and they’ve released three scenarios they think can make it happen
famous scientist, Michio Kaku, thinks there is no real danger
I… well I don’t really care
there’s going to be a day when you, me will just die
so, why be afraid since it is going to happen
now or whenever, it will happen
I’d like it to be in the faaaaar future but I can not control it
and I don’t want to go mad worrying that it may happen sooner then I hope for
so, I hope they’ll fight in court and prove whether those experiments are safe or not

Here’s a vid explaining what happens inside your cells
Some people at Harvard made it here
by the scientists at University of Alberta led by Stephen Barr, a molecular virologist.
the gene named TRIM22 can block HIV in a cell culture and is present in our own body
this gene does not work in people already infected with HIV and the researchers are trying to find out why

and the force is 210 piconewtons to move cobalt atom over a smooth platinum surface and 17 piconewtons to move cobalt atom over a copper surface
this was found out by IBM scientist working with their colleagues from University of Regensburg in Germany

I didn’t know what was his name, but I knew him very well from the various popular science movies that he’s been in
he’s an American theoretical physicist, a very interesting character, explains things in a simple language
now he’s a professor in theoretical physics at City College of New York, hosts two radio programs, writes books and of course, does movies
you can see some of his work at YouTube (just click the link)
anyway, I think I should mention him because he deserves it
here’s his Wikipedia page
no, it’s not science fiction
some scientists at Monash University, Victoria, Australia, made clothes able to clean themselves (imagine that)
they used titanium dioxide nanoparticles on wool, silk etc.
the clothes work by oxidizing (burning, degrading) bacteria and the likes and can even self remove wine stains
I know I’d like to have clothes/bed sheets from those materials
check out the story here
Professor Stan Skafidis and his team of Melbourne University have made this small chip for wireless data exchange.
The chip is about a few millimeters in size, manages data transfers up to 5 gigabits per second, has a radius of 10 meters and works at 60 GHz spectrum.
Wouldn’t it be nice to have so much bandwidth in your room that all the other devices (laptop, tv, mobile phone, camera etc.) can use?
The chip uses less than 2 Watts of power and it costs like USD 10 to make it
Here’s the link
Wow
Scientists are getting smarter by the minute
This time, they made this scanning microscope that can make images on nano scale objecs, even in realtime.
They filmed various materials, E. Coli bacteria, human red blood cells after being treated with antibiotics, Cyanobacteria, virus attacking DNA etc.
