The accidental discovery that flying squirrels have fluorescent belly fur has prompted researchers to ask whether fluorescence in mammals is as rare as previously thought

We love the Colchester Half Marathon and we’re delighted that we’re sponsoring the race again this year. That’s why we’ve been working with Funky Sweets in Stanway to provide free jelly babies for everyone out on the course. You’ll be able to grab your jelly babies on your way through Langham, just in time to give you a much needed energy boost, as you push on to the finish line.
medusa有兩義：「水母」、「蛇髮女妖」。在Lewis Thomas的《一個細胞的告白》（The Fragile Species，廖月娟譯，台北：先覺出版社）中，譯者卻將同作者的《水母與蝸牛》（The Medusa and the Snail：More Notes of a Biology Watcher）譯成《蛇髮女妖與蝸牛》。該書原版的封面是「水母」，而非「蛇髮女妖」:作者用尼泊爾灣的一種水母與蝸牛之間的共生之例，來比喻說，地球也很可能是個「共同體」，
由極多的各自有個性的生命所組成的。
另一方面，在Stefan Zweig 的《與魔鬼博鬥》(王彤譯，北京：東方出版社，1998)的「前言」中，「只有在人生與惡魔相鬥人，只有顫抖著看到他『水母』一樣眼睛的人…」則把「蛇髮女」譯成「水母」。

Medusa stage of a jellyfish (credit: Tom McHugh — Photo Researchers)
In zoology, one of the two principal
cnidarian body forms; the typical form of the
jellyfish. Its name derives from its
tentacles, resembling the snakes borne by
Medusa in place of hair. The medusoid body is bell- or umbrella-shaped. Hanging downward from the center is a stalklike structure, the manubrium, bearing the mouth at its tip. The mouth opens into the main body cavity, which connects with radial canals extending to the outer rim of the bell. A free-swimming form, the medusa moves by rhythmic muscular contractions of the bell, providing a slow propulsive action against the water. The other principal cnidarian body type is the
polyp.

Today London saw the opening of the Jellyfish Theatre, a remarkable new performance venue made entirely from donated, free and
recycled materials.
Reused shipping pallets, recycled nails, old school furniture, and
donated wood scraps have been used to construct this organic 120-seat
temporary auditorium, which is located a mere 10 minutes' walk from the
Globe Theatre on the banks of the Thames. While some see the Jellyfish
Theatre as "
junkitecture"
others see the handmade, recycled theatre as a work of art -- read on
for a look at London's newest performance space and tell us your take
in the comments!

STOCKHOLM, Sweden (AP) -- Two Americans and one Japanese won the Nobel Prize in chemistry on Wednesday for the discovery and development of a brightly glowing protein first seen in jellyfish, work that has helped scientists study how cancer cells spread.
Japan's Osamu Shimomura and Americans Martin Chalfie and Roger Tsien shared the prize for their research on green fluorescent protein, or GFP, the Royal Swedish Academy of Sciences said.
他們利用水母發出的綠色熒光蛋白(GFP)來追查實驗室內進行的生物反應，因此獲獎。
The protein is a widely used laboratory tool to illuminate processes in living organisms, such as development of brain cells or the spread of cancer cells.
