Hyenas that think outside the box solve problems faster

09.08.2012
Innovative problem solving requires trying many different solutions. That’s true for humans, and now Michigan State University researchers show that it’s true for hyenas, too.

The study, published in the current issue of the Proceedings of the Royal Society B, presented steel puzzle boxes with raw meat inside to wild spotted hyenas in Kenya. To get the meat, the hyenas had to slide open a bolt latch.

Even though most of the animals had many opportunities to open the box, only nine out of 62 hyenas succeeded. The successful hyenas tried more solutions, including biting, flipping or pushing the box, than the ones that failed, said MSU zoology graduate student Sarah Benson-Amram.

Another requirement for success was not being afraid to approach new things. The wild hyenas had never seen a steel puzzle box before. And those hyenas that quickly contacted the box when they first saw it were more successful solving the problem than those hyenas that were slower to approach it. Although contacting unknown objects can be quite dangerous for wild animals, this research shows that risk-taking also has some benefits.

Surprisingly, one trait that did not necessarily lead to victory was persistence, said Benson-Amram.

“While those who gave up quickly were more likely to fail, some hyenas that spent more time with the puzzle box appeared to get stuck in a rut and would often try the same solutions over and over again,” she said.

Like humans and other primates, hyenas have relatively large brains, said Kay Holekamp, MSU zoologist and co-author of the paper.

“A likely benefit of large brains is the ability to think flexibly about new situations and come up with solutions to novel problems,” said Holekamp, co-principal investigator at the BEACON Center for the Study of Evolution in Action.

The research was funded in part by the National Science Foundation.

Michigan State University has been working to advance the common good in uncommon ways for more than 150 years. One of the top research universities in the world, MSU focuses its vast resources on creating solutions to some of the world’s most pressing challenges, while providing life-changing opportunities to a diverse and inclusive academic community through more than 200 programs of study in 17 degree-granting colleges.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
