The rising death toll marks Germany's largest mass loss of life in years. Esme Nicholson reports from Berlin.

不断上升的死亡人数标志着德国正在经历数年来规模最大的生命损失。埃斯梅·尼科尔森将从柏林带来报道。

Factors that accelerate bone mass loss and increase the risk of osteoporosis are low estrogen levels, like after menopause, and low serum calcium.

加剧骨量流失和增加骨质疏松风险的因素有：绝经后较低的雌激素水平，以及较低的血清钙水平。

This seasonal cycle, though, is eclipsed by an overall rate of mass loss that would have stunned a glaciologist 50 years ago.

然而， 这个季节性周期被整体质量损失率所掩盖，这在 50 年前会让冰川学家感到震惊。

Indeed, in addition to mass loss, the earth also acquires additional mass from space approximately 40,000 tonnes of cosmic dust settles on the Earth's surface throughout the year.

事实上，除了质量损失外，地球还从太空获得额外质量，全年约有四万吨宇宙尘埃沉降在地球表面。
