Ever wonder how people figured out there used to be such things as dinosaurs? Curious about how scientists learned to reconstruct fossil skeletons? The knowledge we take for granted today was slow in coming, and along the way, scientists and scholars had some weird ideas. This Web site shows some of their mistakes, provides a timeline of events, gives biographies of a few of the people who have gotten us where we are today, and lists resources you can use to learn more.

"Suwan Jayasinghe of University College London and colleagues at Kings College London has used a form of ink-jet printing to create "jets" of living cells. The biophysicists say their technique, which does not destroy the cells, could be used to grow biol

蝸牛會飛？這篇文章探討生活在大陸上的蝸牛如何繁衍到大海洋中的小島。

發現了二十七種以前未發現過的新生物品種，近代罕見。

普林斯頓大學Howard Hughes Medical Institute的科學家Bonnie Bassler最新研究證實，不同物種的細菌能進行對話並能藉此干擾彼此的行為。

功能磁振造影的最新研究結果顯示，男人看到壞人受到懲罰時，不但不會感同身受，甚至會幸災樂禍，但女性看到別人受罰反而都會心生同情。

Lewontin's brilliant unmasking of the ideology behind some kinds of Biology

Lewontin's brilliant unmasking of the ideology behind some kinds of Biology.

Recent research has revealed that brains continue to produce new neurons throughout life, helping create new neural networks.

Female hormones circulating in the brain determine masculine behavior, at least in mice. Estrogen--the quintessential female hormone responsible for regulating the reproductive cycle--turns lady mice into wannabe male mice when it is allowed to penetrate

Scientists have identified cuteness qualities that make good Darwinian sense. The human cuteness detector is set so low that it deems cute almost anything remotely resembling a human baby, and so includes the young of virtually every mammalian species, wo

1986年美國國家衛生研究院科學家Putney J教授提出填充式鈣離子湧入理論(capacitative calcium influx)，這理論也就是現在常稱的鈣池調控鈣離子通道理論(store-operated channels)。在這個理論中，Putney J教授認為：在非興奮細胞中，當細胞內質網中鈣離子的含量下降到一定程度時，就會啟動一些未知機制來打開細胞膜上的鈣池調控鈣離子通道(store-operated channels)，讓細胞外的鈣離子進入細胞內，進而將鈣離子填補回內質網。

Very interesting story of how AIDS is being treated in Botswana. It seems that they are now able to slow the progression of the disease down, but still are not able to stow it totally. It's a step towards a cure...

The digg story about the "dry water" also has some other side-effects. Turns out that if you oxidise this liquid a normal animal (such as a mouse) or human can easily "breathe" the liquid into their lungs and fully function. Here is an experiment on a mou

由"Cell press"所出版的一系列期刊一直在生命科學界扮演執牛耳的角色，在"Cell press"所發行的學術期刊中，又以"Cell"的影響力為最。許多科學家(包括筆者本人)都將能把自己辛苦的研究成果發表在"Cell"視為最高的理想與榮耀。
