canine transmissible venereal tumour (CTVT) suggests it appeared in dogs about 11,000 years ago and preserves the identical DNA of the dog from which it originated, allowing a rare comparison of ancient versus modern animals.

river dolphin previously unknown to science in the Araguaia River of Brazil, only the fifth such freshwater species known and the first discovered since 1918.

ball lightning event on their instruments for the first time with spectrographic readings indicating the composition of the lightning the same as that of the soil, speculating the origin of ball lightning to be a combination of vaporization of silicon oxide and the resulting shockwave of the strike.

tiny sea anemone previously unknown to science living in the Ross Ice Shelf off Antarctica, the first such species living in pure ice instead of soil and the first to live upside down, hanging from the underside of the ice shelf.

measured the distances between galaxies in the universe to within 1% accuracy covering 10,000 square degrees of sky.

electrical charges generated from stresses between rocks that travel vertically along fault lines.

supervolcanoes erupt by very different mechanisms than smaller volcanoes, with the buoyancy of the molten rock creating stress that cracks open the top of the chamber instead of underground pressure building until it breaches the surface.

core duplicons replicated and spread across the chromosomes of select primates between 8 million and 12 million years ago, a genetic characteristic not found in other animals and an evolutionary trait that may have "seeded" chromosomal development and fundamentally influenced human evolution and brain size.

comparable to Earth yet covered with a thick atmosphere of hydrogen and helium like a gas giant challenges theories on planetary formation and the assumption that Earth-mass planets necessarily be of a rocky composition.

nitrogenated polycyclic aromatic hydrocarbons (NPAH) found naturally in combustion products such as vehicle exhaust and charred meat that can be up to hundreds of times more mutagenic than known carcinogens.

closer evolutionary relationship to Australopithecus and modern humans rather than to apes, placing the species in the human evolutionary lineage.
