Baby vampire bat adopted by mom's best friend

Researchers observed a young vampire bat pup being adopted by an unrelated female after its mother died, revealing intimate details about changing social relationships between the mother, pup, and adoptive mother. The study highlights the importance of grooming and food-sharing interactions in forming these relationships.

Environmentally friendly behavior is easy -- tourists just need a 'nudge'

A new study in Frontiers in Communication demonstrates the impact of subtle messaging and cues on encouraging people to show socially desirable behaviors. Travelers were more likely to demonstrate environmentally conscious actions when given a 'nudge' towards the desirable action, whether framed positively or negatively.

A 'skeletal age' calculator to predict bone fracture risk

Researchers developed a computational model to calculate 'skeletal age', a personalised estimate of an individual's risk of bone fracture and premature death. The skeletal age calculator aims to better identify those at risk of a first bone fracture and subsequent fractures, as well as estimates how fractures impact life expectancy.

Bats on the rise

Researchers tracked bats using mini GPS loggers and linked flight data to weather patterns, revealing a roller-coaster flight behavior where bats ascend and descend rapidly. The study found that bats can reach speeds of up to 135 km/h and use topography and nocturnal updrafts to fly high and fast.

How cells recycle the machinery that drives their motility?

Researchers at University of Helsinki discovered a molecular mechanism that promotes cell migration by recycling actin filaments. Twinfilin efficiently removes Capping Protein from filament plus-ends, leading to depolymerization and slower cell migration in its absence.
