Thinking about exercising a muscle can make it stronger. (p. 362)
-
Despite much fanfare about proposed computers based on weird features of quantum mechanics, a whole array of other quantum technologies—navigation devices, chip-making equipment, atomic clocks and more—may also outshine their conventional cousins and be easier to implement than full-blown quantum computers. (p. 364)
-
The dearth of neutrinos from a precision experiment casts some doubt on the prevailing model of particle physics and may indicate that a previously unrecognized extra force exists. (p. 367)
-
A novel type of single-molecule transistor built around a one-molecule-thick layer of organic molecules may eventually lead to faster, denser chips because the channel through which electrons flow is so short. (p. 367)
-
Africanized bees pollinate some of the big Brazilian forest trees now stranded in the middle of cleared land away from their native pollinators. (p. 367)
-
The class of compounds that give beer its bitterness does two more sober jobs in Hypericum flowers. (p. 367)
