When Chinese flying tree frogs (Polypedates dennysi) leap through the forests of China and Southeast Asia, a single missed connection could send them plummeting to a slimy end. Fortunately, they’ve evolved a few lifesaving contortions to grab hold of vertical branches and trunks, according to a 2024 study. Researchers filmed five of the tree frogs making hundreds of jumps in the lab onto poles of various diameters—ranging from dime-size to the width of a toilet paper roll. The amphibians made split-second adjustments depending on the pole’s diameter and how far off course they had veered. They either sailed past their targets before grabbing on with a sticky-padded hand or foot at the last moment, or belly-flopped heavily against the surface and embraced it. By far, the frogs preferred to grab poles with an outstretched hand and whip around. But as the poles grew narrower, they used their feet and their bellies more often to stick the challenging landings. Their angles of approach in the air might dictate whether the animals use their gangly limbs or resort to an inevitable belly-flop impact, the researchers propose.

By analyzing satellite observations of Java Island, Indonesia, researchers found that sinking land will drive up to 85% of relative sea-level rise along Java's coast by 2050, outpacing the effects of global ocean rise. Learn more in @ScienceAdvances: scim.ag/4eSnunH

作为一名喜剧演员,秋凉说她的创作动力是“愤怒”。 她来自中国苏州,2020年和台湾老公结婚,现居新竹。她两年前才第一次接触现场喜剧,刚开始是为了做博士论文而进行研究。 她写段子的灵感主要源于身为在台湾的“陆配”的生活经验。台湾普遍称中国大陆籍配偶为“陆配”或“中配”,他们目前在台湾有超过36万人。 两岸近年压力升高,“陆配”相关的议题也受社会高度关注。秋凉说她在去年台湾的大罢免期间、社会政治意见分歧时感受尤其深刻。





This is fascinating! China's Engine Al unveils the world's first front-flipping robot. Meet PMO1, a 1.38-meter-tall, 40 kg marvel that not only walks with a natural gait but can also pull off a front flip - a move that's notoriously tricky for robots (even harder than backflips).

UBTech Robotics has showcased its humanoid robot Walker S2 playing tennis with a human. Using real-time vision sensors, it tracks the ball, adjusts its position, and returns shots with good accuracy. The robot can also swap its own batteries, allowing it to operate continuously without human help.


Large, warm-bodied fish, like sharks and tuna, may owe their dominance to being able to retain their own body heat, but that advantage comes at a cost. According to a new study in Science, these mesothermic species require nearly four times more energy than other fish, and as oceans warm, their tendency to generate heat faster than they can lose it may push these already vulnerable species closer to the brink of extinction.
