Cyclin-dependent kinase (CDK) activity is essential for eukaryotic cell cycle events. Multiple cyclins activate CDKs in all eukaryotes, but it is unclear whether multiple cyclins are really required for cell cycle progression. It has been argued that cyclins may predominantly act as simple enzymatic activators of CDKs; in opposition to this idea, it has been argued that cyclins might target the...

Two experiments examined the task interference that sometimes accrues from having an intention. In standard prospective memory tasks, latency is often slower to an ongoing task performed concurrently with having an intention than it is when no intention is given. If the locus of this slowing resulted from different attentional allocation policies in the two cases, we predicted that the process ...

When a child acquires her first modal verbs, is she learning how to map words in the language onto innate concepts of possibility, necessity, and impossibility? Or does also have construct concepts? If are constructed, talk about possibilities play role construction process? Exploring this hypothesis space requires testing children's acquisition vocabulary alongside nonverbal tests their concep...

the world of music. Musicians use inexpensive personal computers instead of expensive recording studios to record, mix, and engineer music. Musicians use the Internet to distribute their music for free instead of spending large amounts of money creating CDs, hiring trucks, and shipping them to hundreds of record stores. As the cost to create and distribute recorded music has dropped, the amount...
