Drinking too much coffee or other caffeinated beverages may be a trigger for headaches among migraineurs, according to new research. Mostofsky et al aimed to evaluate the role of caffeinated beverage intake as a potential trigger of migraine headaches on that day or on the following day. Image credit: StockSnap. …

A team of U.S. researchers has discovered a previously undescribed group of small molecule metabolites responsible for the green biofluorescence in two species of sharks. Not only is the newly-discovered chemical mechanism different from how most marine creatures glow, but it may also play other useful roles for the sharks, …

  The European Space Agency (ESA) is hoping to launch a new ExoMars mission to the red planet next year, but the future of that mission is in doubt after a second parachute failure. The ESA confirms a recent parachute test here on Earth has failed, making this the second …

It’s not surprising that quantum physics has a reputation for being weird and counterintuitive. The world we’re living in sure doesn’t feel quantum mechanical. And until the 20th century, everyone assumed that the classical laws of physics devised by Isaac Newton and others — according to which objects have well-defined …

A team of researchers from the University of Exeter, UK, put a bag of chips on the ground and tested how long it took herring gulls (Larus argentatus) to approach when a human was watching them, compared to when the human looked away: on average, gulls took 21 seconds longer …

Dark matter, the mysterious substance that makes up roughly a quarter of the Universe, may have its origin in pre-Big-Bang times, according to a new paper published in the Physical Review Letters. This artist’s impression shows the evolution of the Universe beginning with the Big Bang on the left followed …

In a new study, Dr. Casey Rebholz from the Johns Hopkins Bloomberg School of Public Health and colleagues examined the diets of middle-aged adults living in the United States and found that those following diets higher in plant foods and lower in animal foods had a lower risk of incident …

A team of researchers from the Archaeology Institute at the University of the Highlands and Islands has unearthed the remains of a large Norse building at the site of Skaill farmstead in Westness, Rousay, a small island about two miles (3 km) north of Mainland, the largest island in the …

  NASA’s Curiosity rover has seen a lot of rocks. In fact, that’s almost all it sees on the surface of Mars. Recently, the rover spotted a rock so strange that the team decided to move in for a closer look. The so-called “Strathdon” has dozens of sedimentary layers squished …

A duo of researchers at Purdue University has modified a popular theorem — called Bell’s inequality — for identifying quantum entanglement and applied it to chemical reactions. In this illustration, one photon (purple) carries a million times the energy of another (yellow). Image credit: NASA / Sonoma State University / …
