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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
