Well, lets look at stuff from the last week or two:
Earths atosphere was very hazy 2.5 billion years ago, because it was rich in hydrocarbons.
The reasons giant gas planets have strange orbits
Researchers have updated had-CRUT, one of the main global temperature records, that includes data back to the 1850's, by adding more information from the Arctic region.
Discovered some strange new gamma rays coming from the center of the Milky way.
Found a better hydrogen storage process.
Found out how to make graphene from scratch, which might help us make some amazing materials.
Decided that Asteroid 2012 DA14 will miss our planet by 22,000 miles next February. (Whew! Close!)
Found that Dendritically targeted Bdnf nRNA is essential for energy balance and response to leptin
Found that high-power ultrasound might be used to protect produce from pathogens
Found that black bears heal well when hibernating, without scars.
Have figured out that Planck-mass mirrors provide a new way to probe predictions of quantum gravity.
Found that bone marrow transplants reverse Rett syndrome in mice. This may lead to treatment in humans.
Found that infections as simple as cold viruses might be the trigger for diabetes.
Figured out how to image a living animal with a scanning electron microscope
Sent a message with neutrinos.
Discovered that some bird species apparently have a "heads up" display in their vision that lets them see the earths magnetic field.
Found a species of Japanese honeybees that can kill attacking giant hornet species by cooking the invaders with the heat from their own bodies.
Designed a robotic glove that can help workers reduce the risk of getting repetitive stress injuries.
Use 3D printing technology to print a new jaw for a woman.
Found that if you were to travel faster than the speed of light (probably not possible) you might create large explosions when you get to where you are going.
Come up with a one trillion bits per second chip (1 Thz, vs. the 2.6 Ghz chip I have in my computer today)
Found a way to transfer data between computers at a speed that would allow 500 full length movies to be downloaded in one second.
Reconstructed a dinosaur that had four wings.
Photographen a twister on mars.
Invented Electron Ptychography, which could create the tiniest and sharpest images of cells, etc. ever.
Captured the first ever imagoes of atoms moving inside a molecule
Found more hints of the Higgs boson.
Found a warped spiral galaxy
Developed self-healing hydrogels, which may allow us to make self-healing plastics and other materials.
Discovered that the planet was hit by a large rock 13,000 years ago, which may have led to the last ice age.
Better defined some of the health risks associated with fraking
Would you like me to go on?
You want the big stuff? The big stuff comes from all the little stuff. And every one of those news items is from March, 2012, and I cut it short because I think I have enough to make my point without irking the mods too much with a long post now.
