More than 200 fossilized pterosaur eggs have been found at a single site in China, which could show that the prehistoric flying reptiles cared for their offspring in colonies, according to findings published in Science. Study of a hatchling's nearly complete skeleton indicates that bones used in flight weren't fully developed, suggesting that baby dinosaurs needed assistance from their parents in the early days of life.

Various SARS-related viruses are present in horseshoe bats found in China and could genetically recombine into a new form of the severe acute respiratory syndrome virus. The findings, published in PLOS Pathogens, help shed light on how the original SARS outbreak in 2002 may have begun.
Unenhanced MRI can be used instead of CT imaging on children with suspected appendicitis when sonographic findings are equivocal, researchers reported in Radiology. The retrospective study revealed the staged algorithm had a negative predictive value of 99.5%, more than 98% overall sensitivity and specificity above 97%.
Signals from Earth's gravitational field could help seismologists determine the magnitude of large quakes more quickly, according to a study published in Science. The quicker a temblor's actual size can be determined, the sooner emergency personnel can know how many resources may be needed to respond, researchers say.
A study in Biology Letters demonstrated that shy elk in Alberta, Canada, allow bold magpies to land on them and eat winter ticks, while bold elks scare off magpies and shy magpies avoid elks. The study is among the few to explore how personality shapes interspecies interactions.
Israeli researchers found that subjects missing an arm were able to use their thoughts to move the corresponding arm of an avatar, performing nearly as well as the able-bodied control group. Another study is testing the ability of subjects to operate a surrogate robotic representation using their thoughts.
