A fresh look at Einstein's equations suggests that gravity can sometimes snap and reconnect, similar to magnetic field lines on the sun. The findings hint at a new way that gravity and matter can trade energy.
Researchers created a new map of the fruit fly brain. Then the Internet found it
When the U.S. Federal Reserve announces a change in its interest rate, consumers expect shifts in borrowing costs elsewhere and potential price adjustments for things like housing and some consumer goods. New research, however, shows that stock market analysts generally give a collective "meh" around the time of Fed meetings when it comes to forecasting how much stocks will trade for in the future, called a price target.
To guard proprietary know-how, many firms separate their inventors into independent groups so that no single employee sees too much of the organization's knowledge. New research published in Strategic Management Journal finds that when U.S. states strengthened trade secret law, high-tech firms relied less on this kind of compartmentalization and connected their inventors more broadly—and the inventions that followed had greater technological impact.
Female mandrills are more likely to experience pregnancy loss when they are simultaneously nursing an infant, which may reflect a physiological trade-off between current and future offspring, according to a study by Nikolaos Smit at the Max Planck Institute for Evolutionary Anthropology, Germany, and the University of Turku, Finland, and colleagues, published in PLOS Biology.
The demand for donkey hides has grown exponentially over the past 15 years, driven mainly by demand from China. Lauren Johnston is a specialist on China trade with Africa. She has spent several years looking into the donkey trade, and has just published a book, "China, Africa and the Market for Donkeys." She answers questions about what she found.
Hydrothermal vents lie in perpetual darkness in the depths of the ocean, yet the cells of the vent mussel Bathymodiolus azoricus, which lives 1,700 meters (5,600 feet) below the surface, follow a 24-hour rhythm in the laboratory.
To escape predators, dwarf reed snakes trade slithering for rolling to safety.
More than 107,000 species are used and traded worldwide, more than double previous estimates, according to new research that suggests the true scale may be far greater due to major gaps in trade and wildlife collection data.
Copper is essential for making bronze, which shaped tools, weapons and ornaments across Bronze Age Europe. While many Bronze Age mines have been identified throughout Europe, researchers are still trying to pin down which of them were most active at different times and how far their copper traveled. New research, published in the journal Antiquity, suggests that a series of mines in modern-day Spain and Portugal may have been an important source of copper in the Late Bronze Age, with some of that copper ending up as far away as Scandinavia.
