hybrid whale that is a cross between the Antarctic minke whale and a northern minke whale, two species occupying opposite migratory patterns and hemispheres that were never thought to meet.

parrot-sized theropod (Linhenykus monodactylus) that lived in Mongolia 84-75 million years ago and is the first to have only one finger with a large, single claw on each forelimb.

pink meanie jellyfish (Drymonema larsoni) as a new species has also required the creation of a new family (Drymonematidae) to include all Drymonema species—the first such major addition since 1921.

size-weight illusion was critical to early human's development of the ability to throw objects long distances, a neurological key requiring extremely coordinated timing, motor and perceptive skills on par with social organization and language sharing the posterior parietal cortex in the evolution of the human brain.

ancient cold wind from a prehistoric ice-cap is the reason for the remarkable preservation of animal fossils in the remote Table Mountains of South Africa, providing nutrients to surface vegetation and a stagnant shallow sea that preserved even delicate tissues such as eyes and muscles.

two dozen sungrazing comets, a rate dramatically up from a norm of one every few days, and what may be a precursor of a larger as-yet undetected body moving along the same orbit.

60% the speed of light and enabling the generation of 2 V, as opposed to lighter elements such as tin that are too weak to provide similar attractive force.

astrological signs have shifted by about a month from those established millenia ago.

Cepheid variables, pulsating stars often used as calibration points to measure cosmological distances, can lose mass and shrink over time and thus make measurements of distance more difficult.

NASA's orbiting Fermi Gamma-ray Telescope has detected unexpected positron bursts originating from lightning flashes in thunderstorms on the surface, such radiation focused into a beam by Earth's magnetic field and directed out into space.
Friday, January 14, 2011
smallest exoplanet yet found, a rocky world named Kepler 10b, 560 light years distant with a diameter about 1.4 times that of Earth and about 4.6 times greater mass but that orbits its star too closely to provide an environment suitable for life.
Thursday, January 13, 2011
amorphous metal alloy of palladium, silver and other elements has been developed at Caltech that combines the toughness of glass and the material strength of steel, promising new fatigue-resistant building materials for construction and manufacturing.
Wednesday, January 12, 2011
frog species (Rhacophorus vampyrus) discovered in Vietnam uses its webbed feet to glide from tree to tree and, unique to the species, its tadpoles possess hard black fang-like hooks whose purpse has yet to be determined.
Tuesday, January 11, 2011
green blob (illuminated by a quasar in a nearby galaxy) of mostly hydrogen gas acting as a stellar nursery in a remote area of the universe outside of any galaxy, named Hanny's Voorwerp after its amateur Dutch discoverer.

largest stable synthetic molecule ever made (PG5), with a tree-like structure and diameter of 10 nm and a mass equal to 200 million hydrogen atoms, in the hopes of finding new applications such as drug delivery.
Sunday, January 9, 2011
gamma-ray flares from mechanisms hidden within it that are not clearly understood, producing "the highest particle energies ever associated with a single source."
Saturday, January 8, 2011
large gap in the sizes of planetary objects between 25 and 40 times the mass of Jupiter, providing a natural and usable demarcation in the classification of these objects into gas giants (planets) or brown dwarfs (stars).

Thursday, January 6, 2011
remnants of a star that exploded more than 13 billion years ago, likely one of the very first generation of stars to exist in our universe, whose chemical constituents were almost only hydrogen and helium.
Wednesday, January 5, 2011
oxygen crash in the world's oceans about 499 million years ago that led to rising levels of toxic hydrogen sulfide and a mass extinction of Cambrian species, the cause of which is still unknown.

superconducting materials by mulling them in a water-alcohol (ethanol) mix, with the best results obtained using ordinary red wine.
Monday, January 3, 2011
newly discovered comet spotted last month turns out to be an known asteroid (596 Scheila, 1906), one of a category of hybrid objects called main belt comets with stable inner-solar system orbits that are "dormant" for long periods of time.

new ancient reptile species related to modern crocodiles (Neptunidraco ammoniticus) were discovered in limestone slabs from Ferrara, Italy, destined for kitchen countertops, warehoused in 1955 and only recently examined in 2009.
