Individuals differ, of course, because biological processes are inherently variable. Even so, environmentally induced variation is such that understanding the mechanisms underlying plasticity has moved to centre stage of current research. The term 'plasticity' refers to the changeable character of matter....
Adenoviral vectors are particularly attractive for this approach because they are the most potent at T-cell priming in primates and humans [50]. The main problem of adenoviral vectors is pre-existing immunity to the vector, which can lead to its clearance before a response is elicited to the ...
That might motivate people to kill in order to take or protect those resources. The intellectual and emotional need for those resources is often greater than the reluctance to kill. Not all violent conflicts are over resources, though. What else makes us kill? Women and Men In the United ...
Research suggests that yawning is contagious in humans, primates and even dogs. It’s a well-documented phenomenon, but we have yet to determine why. (6) One theory is that contagious yawning is empathetic social behavior that operates as a kind of communication signal, similar to laughter. ...
Research on some non-human primates, for example, has shown that some yawn-like displays, known as social tension or aggressive yawns, appear to hold a communicative function and are used as a threat display of the canine teeth (e.g., Deputte, 1994, Troisi et al., 1990, Redican, ...
The complicated behaviours crows display, likehoarding foodfor later meals, may have evolved because it helps them survive. Studies also show that, like primates,crows have an impressive working memory, which allows them to remember and use information over short periods. ...

打个比方就好比每天晚上你的电脑或者手机要进入维护模式,进行磁盘碎片整理(memory 的转移和索引),安装固件更新漏洞补丁(增强免疫系统功能)之类的,喝醉昏睡过去大概就等价于强行拔掉电源——虽然两种情况电脑都黑屏了,但是第二天重启的时候立刻就会知道区别很大。而熬夜晚睡则相当于长期运行内存效率低下、没有补丁的“裸奔...
There are undoubtedly parallels in human and animal cognition. That is because there is a continuity in the evolution of our brains that even exist in the invertebrates that the majority of people have no problem stepping on. I see consciousness as layered; we have the near universal sub-consc...
Social homeostasis—the need to socialize Humans have an evolutionarily hardwired need to socialize—though it may not feel like it when deciding between a dinner invite and rewatching "Schitt's Creek." From insects to primates, maintaining social networks iscritical for survivalin theanimal kingdo...
