^How are stars formed?
I make revision videos for AS and A2 level biology, chemistry, physics and maths so if you study any of those then please click here to subscribe to my channel for some sorta lame but hopefully helpful videos :D
Any reblogs would be greatly appreciated especially if you’re likely to have any A level students amongst your followers :) Thank you! <3
THIS IS SO RIDICULOUSLY AWESOME
I WAS MULTITASKING AND I HAD TO STOP AND MAKE THIS FULLSCREEN BECAUSE
I’M IN LOVE
Yes…very much yes!
Doctors are giving AIDS to CANCER. AIDS. TO CANCER. Science is effing incredible.
DUDE GUYS EVERYBODY WATCH THIS THIS IS AWESOME
This is amazing!
OK but…no one is giving AIDS to anyone / anything. The HIV virus, in this case, has been engineered to be a vector for a specific piece of DNA that allowed the t-cells to recognize cancer cells as dangerous invaders, which they previously were not doing.
Viruses function by invading cells and replacing some of the DNA, often making cells into virus factories. But if, instead, we use the virus to change the code of the host cell just a bit, that’s genetic engineering and it’s pretty much how it’s always been done.
So, while cool, it’s not actually the coolest part of the story…the amazing thing is that they were able to find the right genes to insert / activate that would allow this girl’s t-cells to become cancer fighters.
The upworthy article said they injected her with HIV, which is just (as far as I can tell) a blatant and intentional misunderstanding of the truth here.
Nonetheless…still today’s cry.
science has figured out how to open a portal to hell
- alcohol or lighter fluid
- Mix 4 parts powdered sugar with 1 part baking soda.
- Make a mound with the sand. Push a depression into the middle of the sand.
- Pour the alcohol or other fuel into the sand to wet it.
- Pour the sugar and baking soda mixture into the depression.
- Ignite the mound, using a lighter or match.
Oh tumblr, what would we do without you.
REBLOGGING AGAIN FOR THE EXPLANATION
1. dip a spoon of gallium in a glass of hot water
2. make a bubble with smoke instead of air
3. dissolve the tablet in weightlessness
4. set fire to the energy-saving lamp
5. push two identical clouds of smoke
6. create a vacuum in the empty tank
7. set fire to the smoke from the candles
8. overturn the glass with smoke
9. pour the hot solution in a plastic cup [x]
If Earth Had Rings
First off, they would be really pretty to look at. They would also dominate the sky in both night and day at exactly the same place as they would never rise nor set. And at night you would see the Earth’s shadow swing across the rings, like in the 4th photo here.
However, life would be very different on Earth if this were the case. Nocturnal animals would have a hard time being nocturnal, as the light reflecting from the rings would illuminate the night.
Because we are closer to the Sun than Saturn is, the rings would be more rocky than ice, making them less bright but still pretty bright. In fact, you would see far less stars at night (living anywhere other than the equator or the arctic circle) because of the light pollution and not to mention ruin most meteor showers because of that.
During the day the rings would block sunlight in certain regions of the planet creating wild weather cycles and effecting plant life as well. So basically, they would be definitely pretty to look at but they would also make a whole lot of things screwy.

DANGIT EARTH! WHY YOU NO HAVE RINGS!
