Science’s Breakthrough of the Year 2014!


Birds are living dinosaurs and that
shift is one of the most spectacular transitions in the history of life. This year
researchers studying both fossils and modern birds figured out how one
group of dinosaurs became smaller, more adaptable. The change happened pretty quickly setting the stage for the avian
explosion–the arrival modern birds. Think Frankenstein meets the fountain of youth.
Researchers stitched two mice together, one young one old. And connected their
circulatory systems. The connection rejuvenated the brain and
the muscle of the older mouse. It appears young blood contains a factor
that can turn back the clock on the aging process. This year several teams showed that robots, like people can accomplish more by working together.
In one study a thousand robots, each the size of an
American quarter joined together like a marching band to
form squares and letters and shapes. Another team inspired by termites
designed a robot swarm that built three-dimensional structures. Researchers who make computer chips are breaking from their old ways. In 2014 they created the first
large-scale neuromorphic chips. These chips are designed to process
information in ways that are more like a living brain. The chips could make it easier for
machines to carry out perceptual tasks such as vision. And more capable robots could also deal
with a lot of data from sophisticated environmental sensors. Scientists who work with stem cells have reached a long-sought goal. They turned human stem cells into
pancreatic beta cells that can secrete insulin. These important cells are missing in
people who have type 1 diabetes. But doctors can’t yet transplant the new
cells into patients. That’s because the cells will be
rejected as foreign. Still the achievement brings a possible
treatment for diabetes one step closer. When it comes to ancient cave art, researchers have long believed that Europe held the world oldest examples. But this year, researchers announced that
a cave in Indonesia holds hand prints and paintings that
they believe are 35,000 years old. The find suggests that modern humans were pretty creative by the time they left Africa and began settling the rest of the world. In 2013, brain scientists made a cool but kinda creepy discovery. They could
instill a fake memory of fear in mice. To do it they manipulated neurons
with light. And this year they took the method one
step further. They used a similar technique to switch
good memories to fearful ones. And bad memories two more pleasant recollections. In 2014, researchers launched a record
number of CubeSats into space. A CubeSat is a pint-sized low-cost
satellite but they’re starting to do some real
science. They’re cheap and easy to launch. And they can carry very
powerful sensors That means in time constellations
of CubeSats may do the job that now takes a single
complex and pricey mission. The DNA code usually includes just four
letters G C A and T. But this year researchers added a new pair of letters:
X and Y. And they managed to insert these
extra letters into living bacteria. Next up they want to use the extra
DNA letters to code for amino acids that are not normally part of the proteins that organisms make. And now the breakthrough of the year. That is the
sound of a comet. It was recorded by the Rosetta
spacecraft. In August after a 10-year journey
Rosetta became the first probe to orbit a comet. Then in November it made history again, dropping a small lander that drifted to
the comet’s surface. But the landing was awkward– it bounced and ended up in a place where
it could recharge its solar panels. Still it collected a lot of data before
its batteries ran out. Now Rosetta is chasing the comet. It’s
going to watch its jets of gas and dust turn on as the comet nears the Sun. The results could tell scientists a lot
about how our solar system formed and what brought water to Earth.

    if these are the brakethroughs of the year science really isnt going to have anything to offer in the coming years. all this stuff is lame. so specific to the niche of the scientists. we dont care about this. learn about what other people are doing isnt helping anyone or even expanding anyone knowledge. science is a waste of time… if you take time into consideration that is… i bet a scientist would! ha…time pffft whatever thats a lost concept. no one even can understand what time means to us and how irrelevant it is to physics. time could have been vary well caluclated differently. someone just decided to create the wolrd clock and it happened. but the decision doesnt even effect people. just their egos. if u never knew what time it was you would be more aware of the outdoor conditions and less worried about anything happening at a specific point. we would be able to let go and let be instead of always trying to plan a head of time… which is not possible when time isnt real anyway, its just and illusion/concept/mathematical equation. when science lets go of the roots from where we started then we can actually start to see through what we dont know and start to learn by observing instead of DOING. you can only DO so much, the true wisdom is found in observation and patience

    Hey, you forgot that scientists found a way to make fuel out of CO² and H²O, I think that's a pretty important breakthrough aswell xD

    The whole Rosseta thing just brings a bitter taste to my mouth. It's such a shame such a great achievement was overshadowed by butt hurt feminists complaining about a shirt

    oddly, no mention of what kind of shirt a particular scientist was wearing at the time.  It's about time we got our priorities straight!  Great Job Rosetta!

    BTW Matt I've ordered my new gunner girls shirt and fully intend to give a scientific presentation wearing it.  You the Man #RosettaKixAss

    Incredible that you can connect two stitched mices' circulatory systems together without them dying.

    About the stem cells for pancreatic use. Would an :in vivo ' dolly-style cloning of these cells be a plausible line of search?
