Continuing last week’s list of the most interesting scientific events of 2014, here I present 5 more discoveries that marked this year.
6. Curious Curiosity
2014 was Curiosity’s year. It was always present in the news, whether it was because of its 2 Earth years anniversary, its 1 Martian year anniversary, the popular selfie it took of itself or the breathtaking picture of the Moon and the Earth. But Curiosity is not only a great photographer; it’s a great researcher too. Since its arrival on Mars, it has provided us with a lot of information about the Red planet. It has made some curious discoveries on the methane gas concentrations in Mars’ atmosphere, and the deuterium to hydrogen ratio, to shed some light on the controversial history of water in Mars.
7. ALS Fever
The Ice Bucket Challenge swept the world; almost everyone, from celebrities to normal citizens did it, and most donated some amount of money to the ALS Association. Overall, $115 million dollars were raised, and the money will now go into helping people with this condition and into research for a treatment and a cure. Although ALS is not a very common disease, it is a crippling one and can leave those affected with a very disabled life. Therefore, it is absolutely amazing to see the amount of support this charity received, and very hopeful how much effort was put into spreading awareness.
8. The $1000 Genome
A machine that could effectively read a person’s whole genome for less than 1000 dollars was invented this year. This has been a very sought after discovery, and a milestone in the genetic field. Scientists have expected this for years, and it is such an important creation that even prizes were created for those who could accomplish this feat to motivate scientists into researching it. Now that we finally have it, it’s better than we imagined. The machine can actually sequence 5 sets of genomes per day. This could set off a revolution in genomics, and fasten the pace of discovery tremendously.
9. Giant Dinosaur
Dinosaurs have always been known for their size, ferocity and majesty. A new species of dinosaur discovered in Patagonia has been calculated to measure 40m long and 20m high, with an estimated weight of 77 tonnes; that’s 77000 kg! Not only is this the largest dinosaur ever found, but it is also the largest animal to ever walk the Earth. What’s also great bout this discovery is that there were dozens of bones from this creature and allconserved in a great condition, so investigating these bones won’t be too difficult. Unfortunately, it still doesn’t have a name; it is such an important aspect that archeologists want time to think of a name that can represent the importance of this animal.
10. Fake Life Flourishes
Synthetic biology grew greatly this year. On one hand, scientists were able to create a synthetic version of yeast’s chromosome, by substituting the original, natural genes by artificial ones created in the lab. But also, two new bases were proven effective this year. All animals use the usual 4 bases (A, G, C, T) in their genes to code for proteins. But new research has created a bacterium that uses two extra bases, named X and Y, which can code for new amino acids and extend the range of chemicals organisms can produce.
2014 was a great year for science; let’s hope 2015 has even more interesting and fascinating discoveries in store for us!
