Super-Earths May Be Solid Deep Inside Their Mantles
New estimates show that a mineral likely common in these rocky planets’ interiors is resistant to melting, even at high temperatures.
Temperature-induced changes in lipids and fatty acids in spiders
温度引起的蜘蛛脂质和脂肪酸变化摘要温度变化显着影响生物体的发育、繁殖和生理功能，特别是在变温物种中，生理适应对于在不断变化的热条件下维持代谢过程至关重要。脂质成分的改变在防止脂质系统暴露于极端温度时发生故障方面发挥着关键作用。在适应 1、4、25 和 35°C 20 天后，我们分析了蜘蛛 Polybetes pythagoricus 两个关键器官（中肠憩室和肌肉）的脂质和脂肪酸组成。在适应低温的成年肌肉中，我们观察到磷脂酰胆碱和胆固醇增加，而磷脂酰乙醇胺相应减少。在幼年中肠憩室中，最高温度下三酰甘油水平下降，而低温下肌肉中磷脂酰胆碱水平增加。关于脂肪酸，较低的温度通常会导致不饱和脂肪酸（16:
El Niño Warming Is Stronger Than La Niña Cooling. What’s the Right Way to Model This Asymmetry?
A new study looks at daily swings in sea surface temperatures for new insights.
