It may not have been too late to save 'extinct' pigeon

EurekAlert! Biology - Sun, 2017-02-26 21:00
(University of Kent) The Passenger Pigeon, a species of pigeon that died out in the early years of the 20th century, could have been saved even after it was considered doomed to extinction.As a result of this research, conservationists now have a model to test for functional extinction -- defined as a total reproductive failure -- allowing them to question species' extinctions in the past, as well as those that may be heading towards extinction.

Coming soon: Oil spill-mapping swarms of flying drones

EurekAlert! Biology - Sun, 2017-02-26 21:00
(University at Buffalo) Partly inspired by the dynamics of a flock of birds, engineers devised a computational method for drones to quickly record whether they are over water, oil or the edge of the spill. This simple information is shared with the other drones in the swarm, as opposed to sharing actual images or video, which would require too much bandwidth.

Who gets sunburned? Survey finds risk is greater for young adults with melanin-rich skin

EurekAlert! Biology - Sun, 2017-02-26 21:00
(American Osteopathic Association) Results from a study published in The Journal of the American Osteopathic Association point to an urgent need for sunburn prevention among young adults, particularly those who have skin with higher melanin content. Researchers found a surprising correlation between reporting a red or painful sunburn lasting a day or more with being 18 to 29 years of age and not self-identifying as white.

Study shows stem cells fiercely abide by innate developmental timing

EurekAlert! Biology - Sun, 2017-02-26 21:00
(Morgridge Institute for Research) The mystery of what controls the range of developmental clocks in mammals -- from 22 months for an elephant to 12 days for a opossum -- may lie in the strict time-keeping of pluripotent stem cells for each unique species.

Angiography: Miniature particle accelerator saves on contrast agents

EurekAlert! Biology - Sun, 2017-02-26 21:00
(Technical University of Munich (TUM)) The most prevalent method for obtaining images of clogged coronary vessels is coronary angiography. For some patients, however, the contrast agents used in this process can cause health problems. A team at the Technical University of Munich (TUM) has now demonstrated that the required quantity of these substances can be significantly reduced if monoenergetic X-rays from a miniature particle accelerator are used.
