In November 2014, the Philae lander launched by the European Space Agency's Rosetta spacecraft performed the first successful landing on a comet (Philae's target, Comet 67P, pictured).

A number of significant scientific events occurred in 2014, including the first robotic landing on a comet and the first complete stem-cell-assisted recovery from paraplegia. The year also saw a significant expansion in the worldwide use and sophistication of technologies such as unmanned aerial vehicles and wearable electronics.

The United Nations declared 2014 the International Year of Family Farming and Crystallography.

Events, discoveries and inventions

January

1 January 2014: New computer models show that climate change is more sensitive to the effects of cloud formation than previously thought.

• 1 January – A study published in Nature shows that the role of cloud formation in climate change has been underestimated. As a result, global temperatures could increase by 4 °C by 2100 and possibly 8 °C by 2200.
• 2 January
  • Researchers have shown in precise detail how a molecular defect is responsible for myotonic dystrophy type 2, then designed a potential drug candidate to reverse the disease.
  • The asteroid 2014 AA impacts the Earth a few hours after it was first sighted. This was the second time an asteroid was observed before it impacted with Earth (the first being 2008 TC3).
• 5 January – A launch of the communication satellite GSAT-14 from the Satish Dhawan Space Centre aboard the GSLV Mk.II D5 marks the first successful flight of an Indian cryogenic rocket engine, the CE-7.5.
• 6 January – A new way to destroy metastasizing cancer cells traveling through the bloodstream has been discovered by researchers at Cornell University.
• 7 January – NASA releases the deepest image ever taken of a galaxy cluster not long after the Big Bang. The image includes Abell 2744, a galaxy cluster in the Sculptor constellation, and was taken by the Hubble Space Telescope.
• 8 January
  • Using the Sloan Digital Telescope, astronomers have measured the distance to galaxies six billion light-years away – about halfway back to the Big Bang – to an accuracy of just 1 percent. This could aid in the understanding of dark energy, which is thought to be driving the expansion of the universe.
  • A detailed survey of lion populations has revealed that in West Africa, their numbers have collapsed with less than 250 adults remaining.
• 13 January
  • New analysis of a Tiktaalik roseae fossil, dating back 375 million years, has revealed a key link in the evolution of hind limbs that challenges existing theories on how they first developed.
  • Chemists have engineered a plastic artificial cell containing organelles capable of producing the various steps in a chemical reaction.
• 14 January
  • A giant trench deeper than the Grand Canyon has been discovered under Antarctic ice.
  • Illumina, Inc. has demonstrated the first $1,000 genome.
• 16 January

(image)
• 20 January – The ESA's Rosetta spacecraft "wakes up" from hibernation mode to monitor comet 67P/Churyumov–Gerasimenko for the next 16 months as the comet travels into, and then out of, the inner Solar System. The spacecraft is expected to deploy the Philae lander on the comet's surface in November 2014.

  • A new device created by the University of California enables real-time measurements of drug metabolism and concentration in the bloodstream, potentially improving the way doses are administered.
  • Extreme air pollution in Asia and China in particular is having a clear impact on weather and climate patterns, according to a study of aerosols and meteorology over the past 30 years.
• 22 January
  • ESA scientists report the detection, for the first definitive time, of water vapor on the dwarf planet, Ceres, largest object in the asteroid belt. The detection was made by using the far-infrared abilities of the Herschel Space Observatory. The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids."
  • Researchers have determined that the earliest memories prior to the age of three will tend to disappear when a child reaches the age of seven, a phenomenon known as "childhood amnesia."
  • The leech Ozobranchus jantseanus has been shown to survive for 24 hours at −321 °F (−196 °C) and for nine months at −130 °F (−90 °C), a finding that could yield insights into cryopreservation for humans.
• 23 January – A new microscopy technique can eliminate distortion from nano-scale images.
• 24 January – NASA reports that current studies on the planet Mars by the Curiosity and Opportunity rovers will now be searching for evidence of ancient life, including a biosphere based on autotrophic, chemotrophic and/or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments (plains related to ancient rivers or lakes) that may have been habitable. The search for evidence of habitability, taphonomy (related to fossils), and organic carbon on the planet Mars is now a primary NASA objective.
• 26 January – New research indicates that most of the Grand Canyon is much younger than previously thought, having formed as recently as 5 or 6 million years ago, compared to 70 million years as previously estimated.
• 27 January – Genetic analysis of a European male from 7,000 years ago has revealed he had dark skin, dark hair and blue eyes – suggesting that lighter skin colour evolved much later than was previously assumed.

  • The axolotl may have gone extinct in the wild. None were found in a recent survey of its only remaining natural habitat, Lake Xochimilco.
  • Japanese researchers have reported that they developed a way of turning adult mice cells into stem cells by dipping them in acid. If true, this could pave the way for routine use of stem cells in regenerative medicine with a technique that is cheaper, faster and more efficient than before. However, other investigators could not reproduce the effect, and so this "discovery" remains controversial.

  • Scientists report that the composition of water vapor from comet 67P/Churyumov-Gerasimenko, as determined by the Rosetta spacecraft, is substantially different from that found on Earth. That is, the ratio of deuterium to hydrogen in the water from the comet was determined to be three times that found for terrestrial water. This makes it very unlikely that water found on Earth came from comets such as comet 67P/Churyumov-Gerasimenko according to the scientists.
