1+ hour, 28+ min ago  (273+ words) Experimental setup: A 16-meter-long, 1-meter-wide flume with a 1. 5% slope (sketch top, photo bottom). The study investigated entrainment from a mixed bed (432-millimeter diameter), using a light table at the flume's downstream end to record particle count statistics for model validation....

2+ mon, 3+ hour ago  (483+ words) Throughout most of the ocean, aerobic bacteria use dissolved molecular oxygen to decompose organic matter and gain energy, releasing carbon dioxide in the process. But when water ages or is overloaded with organic material, this oxygen is completely consumed, and…...

2+ mon, 2+ week ago  (332+ words) But what makes the mines so eye-catching is also a burden: Current mining methods using brine require vast swaths of land and water, and removing the brine from underground can cause freshwater reservoirs to flow into the open space, lowering…...

7+ mon, 3+ day ago  (670+ words) New laboratory research suggests that some organic molecules previously detected in plumes erupting from Saturn's moon Enceladus may be products of natural radiation, rather than originating from the moon's subsurface ocean. This discovery complicates the assessment of the astrobiological relevance…...

8+ mon, 1+ week ago  (615+ words) Chemical-sniffing sensors, though not yet widely adopted in agriculture or environmental science, represent an emerging field of research and development. The protein has been reprogrammed to mimic the molecular recognition capabilities of animal olfaction, allowing it to detect specific volatile…...
