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 […]

Horses have distinct facial expressions much like humans Despite facial structure differences, horses have similar facial expressions to humans and use these expressions as social cues. Using their Equine Facial Action Coding System, researchers found that horses have 17 distinct facial movements as opposed to human faces, which have 27. The Christian Science Monitor Physicists […]

A prolific star-making dwarf galaxy The Hubble Space Telescope has spotted a busy dwarf galaxy filled with bright, new stars and making even more. NGC 1140 resides in the constellation Eridanus, about 60 million light-years from Earth. Scientists at the European Space Agency say it can’t keep up its robust star production for long because […]

Windbots for the exploration of gas giants NASA is looking to windbots to possibly explore Jupiter, Saturn, Uranus and Neptune, all gas planets that can’t be explored with a rover like those prowling Mars. NASA is financing research into windbots, which would catch a ride on the chaotic gases and gather information that way. Tech […]

Ancient tooth shows signs of early dentistry One of the first examples of dentistry has been found in an ancient molar. Researchers say the 14,000-year-old tooth had been infected and was partially cleaned using flint tools. It predates any undisputed evidence of dental and cranial surgery, currently represented by dental drillings and cranial trephinations dating […]

Mice regain some hearing after gene therapy Researchers were able to partially repair hearing loss in mice using gene therapy, according to a study. The mice were either missing the gene TMC1, responsible for a protein required for proper inner ear hair cell functioning, or it had mutated, and scientists introduced a normal copy of […]
