Wetland reclamation brings limited agricultural gains but high flood exposure
المصدر: Phys.org - latest science and technology news stories · نُشر
Wetland reclamation has long been regarded as a strategy to meet growing food demand, given the favorable soil and water conditions of wetlands. However, the trade-off between potentially greater crop production and the ecological cost of lost wetlands—especially involving flood
Wetland reclamation has long been regarded as a strategy to meet growing food demand, given the favorable soil and water conditions of wetlands. However, the trade-off between potentially greater crop production and the ecological cost of lost wetlands—especially involving flood regulation—has not been well understood.

Matching wastewater treatment to local demand could help China tackle water scarcity
Wastewater reclamation is increasingly regarded as an alternative water source to mitigate water scarcity in China. However, expanding wastewater treatment capacity alone may not be enough to ease this scarcity, since wastewater supply, treatment facilities and reuse demand are n

World-record intensity in attosecond hard-X-ray pulses could unlock closer study of electrons in atoms and molecules
Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair. This

Spiny dogfish blood contains a hormone long thought absent in sharks
Cortisol is a hormone that helps humans and many other animals regulate their energy use and respond to changing conditions. For a long time, sharks and rays were believed to rely on a different steroid hormone for these functions, without producing cortisol themselves. Now, a ne
