就这还快。大家都没见过T版被洪水冲的景象吧？一个帖子刚回复过就找不到了……
现在T版萧条啊~抹泪

PATPAT,已经比本科版好多了,本科版最快最快的时候一天也不到两页帖子.通常一天就半页左右,甚至更少.
每次在页面最下面看到有很多不认识的ID看帖,但总就那么几个人说话.:(

ORZ...今天果然人不多......都没人过来顶......:O
最后顶一帖去吃饭了.
哎,下午还要写ESSAY......SIGH.......:( 最恶心的题目...一点灵感也没有.:mad:

Snake Hearing Is Connected To The Jawbone

Most schoolkids know that snakes can “see” with their noses. Vipers in particular have these organs on their noggins that allow them to see heat, which helps them find their warm-blooded prey. If that’s not wild enough for you, now physicists from Germany and Kansas say that snakes can hear with their jaws, an idea they present in an upcoming issue of Physical Review Letters.

See, snakes don’t have actual ears. At least not on the outside. But they do have fully formed inner ear systems, complete with a cochlea, the fluid-filled bone that harvests sound. But in snakes, the cochlea is connected to…the jawbone. So, if you walk past a snake that’s resting with its head on the ground, the vibrations from your footsteps jiggle the snake’s jaw, which shakes the snake’s cochlea, so the snake can hear you move. In fact, the physicists found that this whole listening-with-your-mouth setup can sense even the tiny vibrations made by scampering rodents or other small prey. And because snakes can unhinge their jaws one side at a time, they may be able to hear in stereo. Which means that tapping on the glass of the rattlesnake exhibit is actually twice as annoying as anyone ever realized.

Comet Dust Seems More Asteroidy

Remember the good old days when we understood our solar system? Then we found out Pluto wasn’t a planet. And now a new study puts comets in question. The data come from NASA’s Stardust mission—that’s the one that scooped up particles from comet Wild 2 and returned to earth two years ago. The conventional wisdom is that comets originated in the outer solar system, then the sun or a planet nudged them into weird orbits.

Well, this study in the journal Science contradicts that wisdom. Turns out that the particles from Wild 2 look like they belong not to a comet but to an asteroid from the inner solar system. In fact, Stardust didn’t capture any of the pre-solar-system stuff that comets should be made of. This means that the distinction between asteroids and comets may be surprisingly blurry. Some comets might have migrated out from the inner solar system. Or there could be lots of inner solar system stuff in the outer solar system. Either way, it’s time to start rewriting those astronomy textbooks…again.
