No matter the size of a nuclear party, some protons and neutrons will pair up and dance
No matter the size of a nuclear party, certain protons and neutrons will always pair up and dance, a new MIT study finds. The results will help map the workings within neutron stars and heavy radioactive nuclei. (2020-11-09)

Cockroach mating habits and developmental features help uncover insect evolution
A research team led by the University of Tsukuba examined the mating habits of an often-overlooked cockroach family, Nocticolidae, to provide clues about insect evolution. Although the studied cockroaches displayed novel wing-flapping behavior prior to copulation, similarities in other mating habits, egg sac handling, and embryonic development between Nocticolidae and sister family Corydiidae suggested that the two groups share a common ancestor. Elucidating these relationships will help infer the evolutionary history of modern-day insects. (2020-11-05)

Vampire bats social distance when they get sick
A new paper in Behavioral Ecology finds that wild vampire bats that are sick spend less time near others from their community, which slows how quickly a disease will spread. The research team had previously seen this behavior in the lab, and used a field experiment to confirm it in the wild. (2020-10-27)

Big-hearted corvids
Taking a look at generosity within the crow family reveals parallels with human evolution. Working together to raise offspring and increased tolerance towards group members contribute to the emergence of generous behavior among ravens, crows, magpies and company. Lisa Horn of the Department of Behavioral and Cognitive Biology found that the social life of corvids is a crucial factor for whether the birds act generously or not. The results have been published in ''eLife''. (2020-10-22)

Chaotic "Lévy walks" are a good strategy for animals
A paper published in the Proceedings of the National Academy of Science (PNAS) explains the advantage that animals have of using a specific type of chaotic type of movement called a ''Lévy walk,'' and how this type of behavior emerges. Using computer modeling, the author shows that this type of movement can allow animals to make flexible decisions between ''exploitation'' and ''exploring'' in an environment. (2020-09-17)

How bacteria adhere to fiber in the gut
Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the University of Basel and ETH Zurich published their results in the journal ''Nature Communications''. (2020-08-28)

Pain 'catastrophizing' may lead to little exercise, more time sedentary
Chronic pain affects the majority of older adults in the US, and getting enough exercise plays a key role in pain management. New research suggests that how people think about their pain can have a significant effect on whether they get enough physical activity - or if they spend more time sedentary. (2020-08-25)

Mismatched caregiver-infant interactions during feeding could boost babies' risk of later obesity
A new integrative review examined evidence related to infants' self-regulation of behavior and emotion, and how that relates to interactions when they are fed by their caregivers, including how those interactions may derail infants' ability to regulate their intake of food. The review found that infants who are fed in the absence of hunger or beyond fullness may develop skewed perceptions of hunger and fullness, which could increase their risk of obesity and related health problems later in life. (2020-07-14)
