1. Scientists are working on a graphene-based sieve that turns seawater into drinking water
As if graphene wasn't awesome enough, back in April researchers achieved a major turning point in the quest for efficient desalination by announcing the invention of a graphene-oxide membrane that sieves salt right out of seawater.
At this stage, the technique is still limited to the lab, but it's a demonstration of how we could one day quickly and easily turn one of our most abundant resources, seawater, into one of our most scarce - clean drinking water.
2. You no longer need to pay ridiculous amounts to access peer-reviewed science research
The scientific community is fighting back against crazy paywalls, with a new study showing that more than a quarter of all scientific papers are now available free online thanks to the Unpaywall app.
3. We just discovered a vitamin that could reduce the incidence of birth defects and miscarriages worldwide
In what scientists are calling "the most important discovery for pregnant women since folate", a 12-year study has revealed that women could avoid miscarriages and birth defects by simply taking vitamin B3 during pregnancy.
4. Researchers are finally beginning to understand how we can repair spinal cord injuries
There's nothing simple about repairing spinal cord injuries. But new research has pinned down how one of the most cutting edge techniques works, and in particular how the body can repair itself with a little prompting from surgeons.
By finally understanding how spinal cord injuries can heal, researchers will eventually be able to develop even more effective treatments that could potentially go as far as reversing paralysis and other nervous system damage.
5. Hyperloops are coming!!
The hyperloop transport system is a brain child of Elon Musk that promises to shuttle people in tube-contained pods between cities at crazy speeds of roughly 1,126 km/h (700 mph). That's New York to Washington DC in around 29 minutes.
So far test hyperloops are being built in the US, the Netherlands, Slovakia, and the Czech Republic. The goal is to have a Hyperloop system between Amsterdam and Paris by 2021.
There's even a (slightly crazy) proposal to turn the US/Mexico border wall into a giant hyperloop.
6. Scientists are fighting back against antibiotic resistance
The United Nations has declared antibiotic resistance a 'fundamental threat' to global health, which some scientists predict could kill 10 million people annually by 2050. But we haven't lost the battle yet.
At the start of this year, scientists announced the development of a molecule that reverses antibiotic resistance in multiple strains of bacteria at once, making it one of the most promising advances we've had to date in the fight against superbugs.
And Australian PhD student Shu Lam has the research community freaking out over a way to actually kill bacteria in the first place... without antibiotics. She's developed a star-shaped polymer that can kill six different superbug strains without antibiotics, simply by ripping apart their cell walls.
7. NASA has released all its research to the public for free
Last year, NASA announced that any published research funded by the space agency will now be available at no cost, launching a new public web portal that anybody can access.
The free online archive comes in response to a new NASA policy, which requires that any NASA-funded research articles in peer-reviewed journals be publicly accessible within one year of publication.
And last but definitely not least...
8. Scientists have classified a brand new type of celestial phenomenon... and they named it Steve.
Steve the 'aurora' was the feel-good story of 2017.
But this year, scientists found out that Steve isn't actually an aurora at all - even cooler, it's an entirely new type of celestial phenomenon we hadn't seen before and are still learning more about.
The new astronomical phenomenon looks like a ribbon of flickering light, and has been spotted in the high latitudes of the northern hemisphere.
Check out below how awesome Steve looks in all his glory. See? Life isn't all bad.
