Researchers at the University of Sheffield have shown that babies can be taught to distinguish between different monkey faces in the same way that they distinguish individual human faces. The team had previously demonstrated that babies begin life with a general ability to distinguish faces, regardless of species, but that this ability becomes more specialised around the age of 9 months. However, this new study, published in the Proceedings of the National Academy of Sciences, shows that children can retain the ability to distinguish between other species’ faces if they are exposed to them on a regular basis.
Dr Olivier Pascalis, of the Department of Psychology at the University of Sheffield explains, “Face recognition is remarkable in that it is a cognitive development that actually involves a loss of ability. Basically, until around 6 months old babies can recognise individuals from any species but, by the age of nine months they have ‘tuned in’ to human faces, giving them an ability to spot smaller differences between human faces, but eroding the ability to recognise animals from other species.
“Our experiment aimed to discover whether this ‘tuning in’ effect was due to babies being exposed to human faces more often than to other species, or whether it is something that happens over time, regardless of environment.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
