Still trying to make sense of New Horizons’ Pluto data Pluto’s frozen mountain ranges Norgay Montes and Hillary Montes are among many of the dwarf planet’s features described in the first published study of data gathered so far from the close flyby of NASA’s New Horizons spacecraft in July. The mission scientists acknowledge they still […]

Portion of rat brain reconstructed in computer A group of 82 neuroscientists have built a portion of a rat’s brain in a computer. The reconstruction is the work of the controversial Blue Brain Project, which hopes to complete a rat brain and move on to a human brain one day. The computerized brain section, culled […]

Volcanoes, asteroid may have killed dinosaurs Researchers studying ancient lava flows in India say volcanic eruptions, combined with an asteroid strike, caused the mass extinction of dinosaurs some 66 million years ago. Los Angeles Times New Zealand fish jumps out of water to hunt prey Researchers in New Zealand have discovered that the banded kokopu […]

Gravitational waves from binary black holes milder than thought Black holes rotating around each other on a collision course create milder gravitational waves than previously thought, a study published online in Science suggests. Scientists studying pulsars with super-sensitive equipment for 11 years looking for evidence of gravitational waves coming from binary black holes haven’t found […]

A predicted collision between pair of black holes The prediction late last year of a collision between a pair of supermassive black holes in a galaxy about 3.5 billion light-years from Earth has gotten support from a new study by scientists at Columbia University. Last year, scientists noticed a flickering pulse from the galaxy’s quasar […]

Could we instantly I.D. pathogens by their glow? It can take days to identify pathogens by swabs and cultures. A new technique uses spectroscopy to see immediately the light bacteria emit. Futurity Old, distant galaxy baffles scientists A galaxy described as the oldest and most distant to be observed has perplexed scientists, and may cause […]

Carbon dating suggests Quran fragments could be older than once thought Fragments of what’s believed to be the world’s oldest Quran may be older than previously thought, even possibly predating the prophet Muhammad, according to researchers at Oxford University. The text was initially tested by Birmingham University, which used radiocarbon dating to suggest the fragments […]

New mathematical definition may help identify chaos A new mathematical definition looks to describe the potential for chaos. The theory is roughly based on something akin to entropy, the degree of randomness within a system. “You could say you have chaos if you have exponential growth of uncertainty. That could happen in relatively simple systems […]

Scientists in Antarctica find evidence of neutrinos’ existence The existence of cosmic neutrinos has been confirmed by scientists at the IceCube Neutrino Observatory in Antarctica. Researchers combed through years of data collected by sensors buried in the ice and pinpointed 21 ultra high-energy muons created by rare neutrino interactions with other particles. They say the […]

Small Jupiter-like exoplanet viewed directly by Earth-based telescope An exoplanet resembling a young Jupiter has been found by astronomers using an Earth-based telescope, the Gemini Planet Imager in Chile, according to findings published online in Science. The gas giant has been dubbed 51 Eridani b and is about 96 light-years from Earth. “To detect planets […]
