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
Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription drivers by reconstructing transcription outside of the
Adelaide University researchers have shown that pairing sniffer dogs with a simple air-sampling device could dramatically improve the detection of illegally trafficked wildlife hidden inside shipping containers.
Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there's a downside to this protective mechanism: the plant's growth is suppressed when its immune system is turned on. Colorado State
A horse's whinny is an unusually distinctive mix of sounds including both high and low frequencies. Reporting in Current Biology, researchers demonstrate how horses produce high-frequency sounds that defy their large size while simultaneously producing lower tones: they whistle
A land dispute may have led to the massacre 3,000 years ago, suggesting Europe’s transition to farming wasn’t always peaceful.
Biodiversity is changing across the planet, yet governments still lack the robust, consistent data needed to track these changes and guide effective conservation. Now, a new study led by the University of Amsterdam (UvA), the German Center for Integrative Biodiversity Research
In 2013, farmers in the highlands of Ethiopia began to notice something unsettling: a familiar variety of wheat was failing in an unfamiliar way. Stems weakened, plants collapsed, and fields that had once held firm against disease were suddenly vulnerable. Three years later,
A century after Erwin Schrödinger sketched out a bold vision for how we perceive color, scientists have finally filled in the missing pieces. A Los Alamos team used advanced geometry to show that hue, saturation, and lightness aren’t shaped by culture or experience — they’re
Traumatic experiences can have ripple effects that permeate across many aspects of people's lives. For students, adverse childhood experiences have been shown to impact attention, memory, language development and relational functioning—the exact skills learning relies on.
Can students be on the front lines of conservation? A new Canada-wide study, published in Metabarcoding and Metagenomics, suggests they can. The efforts of some 5,000 students produced data detailed enough to reveal complex ecological networks hidden inside a small PVC and
