Squid Were on the Move Before the Chicxulub Impact

Katherine Kornei, Science Writer by Katherine Kornei 23 September 202623 September 2026

The cephalopods had already significantly dispersed throughout the world’s oceans 67 million years ago, paving the way for their modern-day ubiquity.

两张图表展示了ENSO的不对称性。左侧标有“日变化”的图表显示,海表温度白天高于夜间。右侧标有“ENSO不对称性”的图表包含两条线,横轴为时间,纵轴为温度。两条线在中间达到峰值,但标有“厄尔尼诺”的红色线条峰值高于标有“拉尼娜”的蓝色线条。

厄尔尼诺的增温效应强于拉尼娜的降温效应。如何准确模拟这种不对称性?

by Nathaniel Scharping 26 August 202626 August 2026

一项新研究分析了海表温度的每日波动,以期获得新的见解。

Two charts show the way that ENSO is asymmetrical. On the left, a chart labeled “Diurnal variation” shows how sea surface temperature is higher during the day than at night. On the right, a chart labeled “ENSO asymmetry” shows two lines, with time on the x axis and temperature on the y axis. Both lines peak in the middle, but the red line labeled “El Niño” has a higher peak than the blue line labeled “La Niña.”

A Cryobank Network Grows in the Coral Triangle

by J. Besl 5 December 20251 January 2026

As the ocean becomes increasingly inhospitable for corals, researchers in the Coral Triangle are turning to cryopreservation to freeze, thaw, and save the region’s hundreds of coral species.
