Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new exoplanet orbiting a distant star known as TIC-65910228. The newfound alien world is slightly larger and nearly five times more massive than Jupiter. The
A recently discovered Greek inscription at the base of a column inside the Great Mosque of Homs in Syria has rekindled a longstanding scholarly debate about the exact location of the Temple of the sun, whose high priest ascended to the Roman imperial throne in the third century
A key question in any discussion about climate is "How much rain fell?" But perhaps there is an even more important one. Like any household budget, the global water economy is based on "income," that is, water entering the system as precipitation, and "expenditure"—water
Thick cloud cover can completely obscure the surface of the Earth from satellite view, while thinner haze and shadows distort the image of rural and urban regions. As such, many remote sensing images for monitoring climate, crops, and urban growth are only partially usable.
An economic study calculates the effectiveness of a novel policy instrument: The underlying idea is that you are allowed to release the climate gas CO₂ into the atmosphere—but only if you promise to "clean up" later through carbon removal. The market forces activated by
Love is in the air for the vinegar fly. Drosophila melanogaster has long been a model for understanding how brains translate sensory information into courtship behavior. Male flies perform a multitude of romantic actions—orienting, tapping, chasing and singing—directed toward
Far beneath the Atlantic Ocean, about 1,000 kilometers off Portugal’s coast, lies a colossal underwater canyon system that dwarfs even the Grand Canyon. Known as the King’s Trough Complex, this 500-kilometer stretch of trenches and deep basins formed not from rushing water, but
How we feel about a night’s sleep can have a bigger impact on mood and grogginess than actual hours of rest. Here’s how to change your mindset to feel more energised
