CRISPR for gene editing:"Since 2013, the CRISPR/Cas system has been used for gene editing (adding, disrupting or changing the sequence of specific genes) and gene regulation in species throughout the tree of life. By delivering the Cas9 protein and appropriate guide RNAs into a cell, the organism's genome can be cut at any desired location."(From Wikipedia <a href="https://en.wikipedia.org/wiki/CRISPR" rel="nofollow">https://en.wikipedia.org/wiki/CRISPR</a>)Edit: Hear a recent Radiolab episode on the topic (<a href="http://www.radiolab.org/story/antibodies-part-1-crispr/" rel="nofollow">http://www.radiolab.org/story/antibodies-part-1-crispr/</a>)

The revolution in biotech happening from the discovery of the CRISPR process will be as important as the semiconductor in the long run: <a href="https://en.wikipedia.org/wiki/CRISPR" rel="nofollow">https://en.wikipedia.org/wiki/CRISPR</a>Neural networks via deep learning started showing incredible results the last few years (after about 40 years of development) across a range of fields, including speech recognition, machine vision, and more. It's still early days, but combining reinforcement learning with neural networks looks like it will be very exciting too: <a href="http://www.nature.com/nature/journal/v518/n7540/full/nature14236.html" rel="nofollow">http://www.nature.com/nature/journal/v518/n7540/full/nature1...</a>

I would say, in no particular order:<pre><code> * the fact that many of the dinosaurs had feathers * myriad of exoplanets * water on Mars (and many other new data on the planet) * Higg's boson (confirmed to 99.999% certainty) * Neanderthal genes present in modern humans * new ancient Mayan cities </code></pre> That's it from me for starters, hopefully others will join in.

In solar cell research, the biggest recent breakthrough was probably the creation of efficient perovskite solar cells [1]. They're cheap, easy to make, and their efficiency in the lab is rising more rapidly than that of just about any other research cell since NREL began tracking (up from 3.5% in 2009 to 20.1% today) [2,3]. If their chemical stability problems can be resolved, they'll have big commercial applications.[1] <a href="http://www.sciencemag.org/content/342/6165/1438.2" rel="nofollow">http://www.sciencemag.org/content/342/6165/1438.2</a>[2] <a href="http://www.nrel.gov/ncpv/images/efficiency_chart.jpg" rel="nofollow">http://www.nrel.gov/ncpv/images/efficiency_chart.jpg</a>[3] <a href="http://www.technologyreview.com/news/517811/a-material-that-could-make-solar-power-dirt-cheap/" rel="nofollow">http://www.technologyreview.com/news/517811/a-material-that-...</a>

Not very "fundamental" but I'm very excited about low-power advancements in ICs. There are companies like AmbiqMicro making microcontrollers that are reaching 30uA/MHz and 100nA sleep modes. This is starting to make ambient and RF energy harvesting viable.<a href="http://ambiqmicro.com/low-power-microcontroller" rel="nofollow">http://ambiqmicro.com/low-power-microcontroller</a>

Blockchains. Distributed consensus is incredibly powerful. It will allow us to rebuild our society around individuals instead of corporations and governments that formed because economic transaction costs were so high that economies of scale (and sometimes the use of force) were required to coordinate our society.All economic activity will be blockchain-mediated. It will make us wealthier and freer.

I thought the discovery of the quantity of distinct populations (~5k currently) and densities (relatively even) of upper-ocean viruses was perhaps an under-rated discovery that could lead to more advanced understanding of both the evolution of cellular organisms on earth and our current ecosystem. <a href="https://www.quantamagazine.org/20150521-ocean-viruses/" rel="nofollow">https://www.quantamagazine.org/20150521-ocean-viruses/</a>

I'd say that in terms of what we are able to do next, Graphene wins by a long way. Graphene is remarkable stuff, literally.I'd say in terms of impact on philosophy, religion and way of life, the large number of planets we're discovering.

A VERY specific request, no inventions, just things found and cataloged aka discovered.<a href="http://www.openexoplanetcatalogue.com/systems/" rel="nofollow">http://www.openexoplanetcatalogue.com/systems/</a>Also see pretty much every space probe of the "last few years". Pity you couldn't wait another month for the Pluto flyby, unless it completely fails there will be plenty to talk about.I would imagine the biological sciences could list all kinds of interesting, possibly useful, critters.The geologists and archeologists are always digging something cool up.

This sounds more like an AskReddit post than AskHN... but I'd say printable organs, smaller and smaller computer chips, commercialization of space flight, possible warp drive tech(may get us there in 100+ years, lol not expecting anything soon).. anti-aging (expected to double or triple life expectancy by 2050.) etc...

While it's not really "great", the absence of new fundamental physics this century is certainly striking...OTOH Quantum error correcting codes are pretty bananas. Won't be useful for a good while.<a href="https://en.wikipedia.org/wiki/Quantum_error_correction" rel="nofollow">https://en.wikipedia.org/wiki/Quantum_error_correction</a>EDIT: the correct answer is that gene editing stuff though.

Though theoretically predicted long ago, I suppose the Higgs boson can be said to have been "discovered" in 2012 when its presence was first confirmed.

Vampires! Technically speaking, parabiosis.
