Loose skin and 'slack volume' protect Hagfish from shark bites

Added: 15.12.2017 15:41 | 0 views | 0 comments

#zrodlo

New research shows how hagfishes survive an initial attack from predators before they release large volumes of slime to defend themselves. Because the slime is released after they are attacked, this defense strategy is only effective if they survive the initial bite. Results show that hagfish skin is not puncture resistant; it is both unattached and flaccid, which helps avoid internal damage from penetrating teeth.

#zrodlo

Researchers report statistical evidence that children exposed to airborne coarse particulate matter — a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber — are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.

#zrodlo

Imaging at the nanoscale is important to a plethora of modern applications in materials science, physics, biology, medicine and other fields. Limitations of current techniques are, e.g. their resolution, imaging speed or the inability to look behind opaque objects with arbitrary shapes. Scientists have now demonstrated a method for meeting this challenge with stunning properties.
