New study shows animals may get used to drones

A new study in Conservation Physiology shows that over time, bears get used to drones. Previous work indicated that animals behave fearfully or show a stress response near drone flights. Using heart monitors to gauge stress, ...

How antibiotics spread resistance

Bacteria can become insensitive to antibiotics by picking up resistance genes from the environment. Unfortunately for patients, the stress response induced by antibiotics activates competence in microorganisms, the ability ...

Traffic noise stresses out frogs, but some have adapted

Frogs from noisy ponds near highways have altered stress and immune profiles compared to frogs from more quiet ponds—changes that reduce the negative effects of traffic noise on the amphibians. According to a new study, ...

Study provides whole-system view of plant cold stress

When temperatures drop, plants can't bundle up. Stuck outside, exposed, plants instead undergo a series of biochemical changes that protect cells from damage. Scientists have described these changes and identified some of ...

Fish undisturbed by flash photography

Fish experience stress, as do mammals and humans. When under stress, fish release the hormones adrenaline and cortisol. A team of scientists spearheaded by IGB has investigated whether flash photography induces an increase ...
