By measuring the melting temperature of iron under high transient pressure, researchers set a limit on the temperature at the boundary between the inner and outer cores.

Sentient Planets & World Consciousnesses
We often imagine that our planet might be a sentient entity — Gaia — but could something like this evolve under known science? And might a conscious world be something we might create in the future?

Paranoia may be—in part—a visual problem
Could complex beliefs like paranoia have roots in something as basic as vision? A new Yale study finds evidence that they might.
When completing a visual perception task, in which participants had to identify whether one moving dot was chasing another moving dot, those with greater tendencies toward paranoid thinking (believing others intend them harm) and teleological thinking (ascribing excessive meaning and purpose to events) performed worse than their counterparts, the study found. Those individuals more often—and confidently—claimed one dot was chasing the other when it wasn’t.
The findings, published in the journal Communications Psychology, suggest that in the future, testing for illnesses like schizophrenia could be done with a simple eye test.
Six-month-old infants use cross-modal synchrony to identify novel communicative signals
Just as humans can use the taps of Morse Code or the patterns of smoke signals to communicate precise messages, infants show a remarkable flexibility to interpret nonlinguistic signals to aid their learning.
But what conditions are required for babies to elevate new nonlinguistic signals in this way? And how early can they do so?
Sandra Waxman, the study’s senior author, and her colleagues discovered that infants as young as six months old were able to harness nonlinguistic signals for learning, a surprising finding because at this age, babies are just beginning to acquire their own language.
The evidence revealed the conditions under which babies conferred communicative status to the novel tone signals and then recruited them to successfully complete a learning task. Infants’ success did not depend on whether the signals were produced by humans, or in a give-and-take interchange between individuals. Instead, what mattered was cross-modal temporal synchrony, in other words, if the method of signal delivery included synchronized sound and movement.
