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 […]

Some pharmaceutical painkillers and analgesics like Noscapine, papaverine and tubocurarine or the most famous opioids codeine or morphine are Benzylisoquinoline derivatives. Few of them are used daily for thousands of people to relieve a variety of physical pains. However, due to their rather complex biosynthesis, they are still obtained by processing plant extracts (mainly from […]

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 […]

Undoubtedly, the most popular aspect of driverless cars, autonomous drones and quadrotors are the cool videos we are getting accustomed to seeing around. However, behind each of those spectacular demonstrations there is a large amount of work, both practical and theoretical. In this series of articles we will shed some light on one of the […]

As the search for renewable energy sources has intensified, the discovery of efficient and cheap technologies for exploiting the energy from the sunlight has emerged as a key challenge. Higher efficiency plays an increasingly important role in making competitive solar cell designs as the price of silicon continues to drop. At present, the actual silicon […]

Lithium-ion batteries are widely used in portable electronic devices and electric vehicles since their introduction by Sony in 1991. Safety is an important concern since about two billion cells are produced every year but with a one-in-200,000 failure rate. Excessive temperature variations and high temperatures over the melting point of the metallic lithium can cause […]

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 […]

We are all familiar with the equation of ideal gases: PV = nRT. To deduce this equation, an ideal model of the gas is considered. In this model, gases are composed of particles so tiny compared to the volume of the gas that they can be considered zero-volume points in space, and there are no […]

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 […]
