Stuck in the divide
n the nervous system, guidance molecules called semaphorins bind to receptors called plexins to induce motility and regulate axonal pathfinding. Now, Swiercz et al. (page 869) show that plexin-B1, after binding its ligand semaphorin 4D (Sema4D), forms a heterodimer with the tyrosine kinase ErbB2. This raises the intriguing possibility that the semaphorins and the EGF-like ligands of ErbB recept...
متن کاملStuck in the mud.
One had to be quick. Walk like a stork. Easier said than done, carrying a backpack full of equipment, buckets full of samples and a shovel over the shoulder, sinking knee-deep into the mud under the scorching tropical sun and watching out for crocodiles.

It is sometimes claimed that non-human animals (and perhaps also young children) live their lives entirely in the present and are cognitively 'stuck in time'. Adult humans, by contrast, are said to be able to engage in 'mental time travel'. One possible way of making sense of this distinction is in terms of the idea that animals and young children cannot engage in tensed thought, which might se...
متن کاملAre animals stuck in time?
People can time travel cognitively because they can remember events having occurred at particular times in the past (episodic memory) and because they can anticipate new events occurring at particular times in the future. The ability to assign points in time to events arises from human development of a sense of time and its accompanying time-keeping technology. The hypothesis is advanced that a...
متن کاملStuck on a channel
Stuck on a channel ctive Ca 2 channels, according to Hudmon et al. (page 537), get their own dedicated Ca 2 sensors that cause well-used channels to open with gusto. Some Ca 2 channels, including voltage-gated L-type channels, let through more Ca 2 per opening when they are used frequently. This positive feedback, known as facilitation, allows fast-beating cardiac cells, for instance, to beat h...
