Despite the prominent health threat posed by fine particulate pollution, fundamental aspects of its formation and evolution continue to elude scientists.
Rough seas prompted SpaceX on Saturday to delay the emergency escape test of its new crew capsule by a day.
Neutron spectroscopy is an important tool for studying magnetic and thermoelectric properties in materials. But often the resolution, or the ability of the instrument to see fine details, is too coarse to clearly observe features identifying novel phenomena in new advanced materials.
Australia’s unprecedented wildfires season has so far charred 40,000 square miles (104,000 square kilometers) of brushland, rainforests, and national parks—killing by one estimate more than a billion wild animals. Scientists fear some of the island continent’s unique and colorful species may not recover. For others, they are trying to throw lifelines.
A highly contagious bird flu has been confirmed at a Czech farm, officials said Saturday after a French farm union warned of the risk of a new outbreak in Europe.
The decision to buy a lottery ticket, gamble on a stock, or buy an insurance policy often comes down to an assessment of risk. How much do I have to lose or gain? For centuries, economists have debated about when somebody should take or walk away from a bet. Now, in new research from Caltech and Yale University, economists are weighing in on the conversation with new mathematical arguments that take a person’s overall uncertainty in life into account. The results show that when somebody’s overall uncertainty—or “background uncertainty”—is large enough compared to a particular small gamble, then the risk of the gamble becomes less significant.
Rain and thunderstorms doused long-burning bushfires across much of eastern Australia Saturday, but they also brought a new threat of flooding in some areas.
Few singers reach their sunset years with the same voice they had in younger days. Singing sparrows are no different. Duke University-led research reveals that elderly swamp sparrows don’t sound quite like they used to—nor do they strike the same fear in other males who may be listening in.
Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined that they also most likely originated from outside of the Solar System. These results improve our understanding of the outer Solar System and beyond.
What makes for an endangered species classification isn’t always obvious.
