Life Cycles; Biking vacations allow family to meet people, observe natureSANDYE VOIGHT
Here we describe an experiment in which simple cooperating lineages of bacteria were propagated under a selective regime that rewarded collective-level persistence. Collectives reproduced via life cycles that either embraced, or purged, cheating types. When embraced, the life cycle alternated between ...

Life Cycles 生命就是一条河-Life is a river.我爷爷经常这样说-That's what granddad always used to say.开始与结束之间 有千万条路线-A beginning, an end, a million different ways in between.他用河流来形容我的一生 如何流动 如何结束-He used a metaphor of my whole life how it ended, flowed...
Although the nature, timing and duration of the movements differ, as does the depth of our knowledge of any one species, this comparative approach may help direct further studies of migratory patterns and potentially uncover commonalities of the underlying endocrine mechanisms regulating life cycles ...
Teaching children about life cycles is a perfect way to help them understand the world around them and to connect them with nature. Children can gain respect for nature when learning about life cycles. 在这个年纪,孩子们通常都是好奇心旺盛,并开始对这个世界的种种提出十万个为什么。为什么丑陋的毛毛...
The university said the findings, published in Nature Chemistry, suggest that environmental factors played a key role in shaping the molecular complexity needed for life to emerge. The research team simulated early Earth conditions by exposing mixtures of organic molecules to repeated wet-dry cycles,...
