As the global climate continues to change, the ability of many animal species to adapt is being put to the test. Bird populations may be at particular risk.
According to the Audubon Society, nearly half of all North American bird species are severely threatened by shifts in climate. The threat reaches beyond North America and could have similar effects on global bird populations.

Little penguins’ personalities may help them cope with climate change
John Cockrem of the Institute of Veterinary, Animal and Biomedial Sciences at Massey University in New Zealand suggests that a bird’s individual personality may be among the factors that could improve its chances of successfully coping with environmental stressors.
He studied differences in the level of the stress hormone corticosterone that native little penguins (Eudyptula minor) secreted when exposed to stressful stimulus.
“There is considerable individual variation in corticosterone responses, and a stimulus that initiates a large response in one bird may initiate a small response in another bird,” Cockrem wrote. “Corticosterone responses and behavioural responses to environmental stimuli are together determined by individual characteristics called personality.
Birds with low corticosterone responses and proactive personalities are likely to be more successful (have greater fitness) in constant or predictable conditions, whilst birds with reactive personalities and high corticosterone responses will be more successful in changing or unpredictable conditions.”
These findings may help in predicting the adaptability of bird species as they face a new normal. Cockrem will present the talk “Corticosterone responses and the ability of birds to cope with environmental change” at the American Physiological Society (APS) intersociety meeting “Comparative Approaches to Grand Challenges in Physiology” on October 8, 2014.
APS jointly hosts this intersociety meeting with the Society for Experimental Biology, Society for Integrative and Comparative Biology, Australian and New Zealand Society for Comparative Physiology and Biochemistry, Canadian Society of Zoologists, Crustacean Society and International Society for Neuroethology.

Physiology is the study of how molecules, cells, tissues and organs function in health and disease. Established in 1887, the American Physiological Society (APS) was the first U.S. society in the biomedical sciences field. The Society represents more than 11,000 members and publishes 14 peer-reviewed journals with a worldwide readership.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
