Asymmetrical magnetic microbeads transform into micro-robots
Janus particles are asymmetrical microscopic spheres with both a magnetic and a non-magnetic half. A new study reveals that the dynamics of such assemblies can be predicted by modelling the interaction of only two particles and simply taking into account their magnetic asymmetry. These findings were recently published in EPJ E by Gabi Steinbach from the Chemnitz University of Technology, Germany, and colleagues at the Helmholtz-Zentrum Dresden-Rossendorf. (2016-07-26)

'Big mama' bonobos help younger females stand up for themselves
Bullying happens in the primate world too, but for young bonobo females, big mama comes to the rescue. Kyoto University primatologists report that bonobo females frequently aid younger females when males behave aggressively towards them. This partly explains how females maintain a superior status in bonobo society. (2016-07-19)

Bacteria avoid age defects through collective behavior
Biophysics: As they age, more and more defects arise in most organisms. Researchers from the Niels Bohr Institute have discovered that microorganisms like bacteria can keep a colony young by practicing a common strategy for propagation. The same may be true for, for example, stem cells in humans. The results have been published in the scientific journal, Cell Systems. (2016-07-14)

A powerful new technology that maps the 'social network' of proteins in breast cancer cells is providing detailed understanding of the disease at a molecular level and could eventually lead to new treatments, Australian scientists say. (2016-07-14)

Ocean warming primary cause of Antarctic Peninsula glacier retreat
A new study has found for the first time that ocean warming is the primary cause of retreat of glaciers on the western Antarctic Peninsula. The Peninsula is one of the largest current contributors to sea-level rise and this new finding will enable researchers to make better predictions of ice loss from this region. (2016-07-14)

Food nudging can help us to eat in a healthier way
What we eat in the canteen and buy in the supermarket for dinner depends on the order in which the dishes are presented, and how easy it is to get to the products. This is the conclusion of a collaborative review of existing research into food 'nudging.' Until now there's been very little research on this topic, but researchers behind the review expect healthy food nudging to be a predominant subject in the coming years. (2016-07-13)

Homo erectus walked as we do
Some 1.5-million-year-old footprints provide a window to the life of Homo erectus. (2016-07-12)

The first evidence of Neanderthal cannibalism in northern Europe is discovered
The remains of at least five individuals retrieved from a site in Goyet (Belgium) display a large proportion of cut marks caused by stone tools when the meat was cut, and the bones display fractures as a result of having been broken to extract the marrow. The Ikerbasque researcher Asier Gómez-Olivencia, who is currently working at the UPV/EHU-University of the Basque Country, has collaborated in this work. (2016-07-07)

How cooperation emerges in competing populations
Social behavior like reaching a consensus is a matter of cooperation. However, individuals in populations often spontaneously compete and only cooperate under certain conditions. These problems are so ubiquitous that physicists have now developed models to understand the underlying logic that drives competition. A new study published in EPJ B shows the dynamics of competing agents with an evolving tendency to collaborate that are linked through a network modelled as a disordered square lattice. (2016-07-07)

Scientists uncover route for finding out what makes individuals nice or nasty
A University of Exeter scientist has helped develop an innovative mathematical model for exploring why some individuals evolve to be genetically programmed to be nice, while others stay nasty. (2016-06-24)

Female blue tits sing in the face of danger
Birdsong has long been associated with courtship or competitive behavior. And males were considered to be more active. A team from Vetmeduni Vienna now shows that female singing is much more common. They demonstrated for the first time a connection between the song of female blue tits and the presence of a predator. This singing appears to be about their own defense. The study was published in the Journal of Ornithology. (2016-06-24)

Fish out of water are more common than thought
Fish have evolved the ability to live on land many times, challenging the perception that this extreme lifestyle shift was likely to have been a rare occurrence in ancient times. UNSW Australia research shows 33 different families of fish have at least one species that demonstrates some terrestrial activity and, in many cases, these behaviors are likely to have evolved independently in the different families. (2016-06-21)

Simple reward-based learning suits adolescents best
Adolescents focus on rewards and are less able to learn to avoid punishment or consider the consequences of alternative actions, finds a new UCL-led study. The findings suggest that that adolescents are more receptive to rewards than they are to punishments of equal value, so it may be useful for parents and teachers to frame things in more positive terms. (2016-06-20)

Carrots and sticks fail to change behaviour in cocaine addiction
People who are addicted to cocaine are particularly prone to developing habits that render their behaviour resistant to change, regardless of the potentially devastating consequences, suggests new research from the University of Cambridge. (2016-06-16)

Map of teenage brain provides evidence of link between antisocial behavior and brain development
The brains of teenagers with serious antisocial behavior problems differ significantly in structure to those of their peers, providing the clearest evidence to date that their behavior stems from changes in brain development in early life, according to new research led by the University of Cambridge and the University of Southampton, in collaboration with the University of Rome Tor Vergata in Italy. (2016-06-15)

Lifestyle habits linked to pain conditions already in childhood
Poor physical fitness and sedentary behavior are linked to increased pain conditions in children as young as 6-8 years old, according to the Physical Activity and Nutrition in Children Study ongoing at the University of Eastern Finland. The findings were published in the Journal of Pain. (2016-06-14)

Darwin's 'true century' was delayed until animal biographies illuminated social evolution
Over the last 50 years, long-term studies following individual animals over entire lifespans have allowed insight into the evolutionary influence of social behavior -- finally fulfilling the holistic approach to evolution first suggested by Darwin, argues the author of a new milestone work on mammal societies. (2016-06-13)

Camouflage influences life-and-death decisions that animals make
Nesting birds time their escape from an approaching predator depending on how well camouflaged their eggs and their own bodies are, researchers from the University of Exeter and the University of Cambridge have discovered. (2016-06-09)

How honeybees do without males
An isolated population of honeybees, the Cape bees, living in South Africa has evolved a strategy to reproduce without males. A research team from Uppsala University has sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees to find out the genetic mechanisms behind their asexual reproduction. (2016-06-09)

How did ignoring people for our smartphones become the norm?
It's common now to see people snubbing social companions to concentrate on their smartphone. But what causes this behavior -- known as 'phubbing' -- and how did it come to be regarded as normal? (2016-06-07)

Snails reveal how 2 brain cells can hold the key to decision making
Scientists at the University of Sussex have discovered how just two neurons in the brain hold the key to explaining how complex behavioral decisions are made. (2016-06-03)

Sparrows with unfaithful 'wives' care less for their young
A new study shows that male sparrows can judge if a spouse is prone to infidelity, providing less food for their brood if their partner is unfaithful. (2016-05-31)

The mysterious sexual life of the most primitive dragonfly
The dragonfly considered the most primitive in the world lives in Australia and Tasmania, and was believed to be extinct four decades ago. But it is far from being so. A Galician researcher has observed thousands of these insects in one of the few habitats in which it has been detected and it displays sexual behavior that is unique, not only directed towards reproduction. (2016-05-31)

It pays to increase energy consumption
Researchers at Aarhus University have carried out extensive theoretical mappings of the way private consumers can save money for heating in a modern supply system based on electricity. Surprisingly enough, the mapping shows that by using approximately 10 percent more energy for heating, it is possible to save about 10 percent on the heating bill, at the same time as protecting the environment with lower carbon dioxide emission. (2016-05-31)

Workaholism tied to psychiatric disorders
A national study shows that workaholics score higher on psychiatric symptoms like ADHD, OCD, anxiety, and depression than non-workaholics. (2016-05-25)

What can Pavlov's dogs tell us about drinking?
Pavlovian cues that predict alcohol can lead us toward addiction. And sometimes those cues can become desirable in and of themselves, as shown in a new study published in Frontiers in Behavioral Neuroscience by researchers from Concordia University in Montreal. (2016-05-25)

Scientists explore new concepts of plant behavior and interactions
While a lot is already known about plant perception, our ecological understanding of plants has largely focused on seeing plants as the sum of a series of building blocks or traits. A new special issue using ideas from behavioral ecology to understand plants, edited by JC Cahill of the University of Alberta, and published by AoB PLANTS, gathers researchers who have taken a new approach, theorizing plant activity in terms of behavior. (2016-05-25)
