One explanation for why some species decline is that human modifications make existing habitat unsuitable for them. For other species, these modifications are advantageous and make the habitat available for them to expand into. Researchers from the Max Planck Institute of Evolutionary Anthropology in Germany, and the University of California Santa Barbara and the University of Rochester in the USA investigated the role that increased habitat availability might have played. They compared the rapidly expanding great-tailed grackle with their closest relative, the boat-tailed grackle, who are not ...

More than half of volunteer community health care workers in 19 countries experience labor exploitation, including sub-minimum-wage pay and excess work hours, Mount Sinai researchers report in the first systematic review of the subject. The researchers focused on two-tiered or dual-cadre programs, in which salaried community health workers work alongside a volunteer group of community health workers. The study, published in Lancet Global Health on September 19, provides a global estimate of the presence, prevalence, and magnitude of labor ...

Multi-storey buildings are assembled over cautiously to withstand wind strengths, researchers have found. This is because there are several difficulties in estimating damping – the method of removing energy in order to control vibratory motion like noise and mechanical oscillation, accurately in high-rise buildings The findings, published today in the journal Structures, addresses the draw back and were compiled by a team at the University of Bristol who studied the damping and natural frequency characteristics of a 150 m tall building in London (UK) obtained from the full-scale wind-induced responses using a minimal monitoring system. In general, the response ...

They found that only one out of four ...

Is it an eagle? A birdie? No, it’s a gator.  The Rosenblatt Lab at the University of North Florida has recently published a study finding that living on a golf course dramatically changes alligator feeding habits.  The study suggests that land use changes can significantly alter the feeding habits of large predators. Changes in habitat and prey availability caused gators living on golf courses to have different dietary patterns and access to different prey communities compared to those living in natural habitats. As ...

Chemotherapy as a treatment for cancer is one of the major medical success stories of the 20th century, but it's far from perfect. Anyone who has been through chemotherapy or who has had a friend or loved one go through it will be familiar with its many side effects: hair loss, nausea, weakened immune system, and even infertility and nerve damage. This is because chemotherapy drugs are toxic. They're meant to kill cancer cells by poisoning them, but since cancer cells derive from healthy cells and are substantially similar to them, it is difficult to create a drug that kills them without also harming healthy tissue. But ...

Would you help a complete stranger in desperate need of money, based solely on their social media posts? Simon Fraser University professor and bioethicist Jeremy Snyder examines the complex dimensions of this question in his new book, Appealing to the Crowd: The Ethical, Political, and Practical Dimensions of Donation-Based Crowdfunding (Oxford University Press, 2023) which highlights how online crowdfunding – while helping to meet immediate needs – also impacts privacy and dignity, worsens inequalities, doesn’t solve systemic issues and most often, falls short of its goals.

ITHACA, N.Y.- Though human-made ponds both sequester and release greenhouse gases, when added up, they may be net emitters, according to two related studies by Cornell University researchers. The studies begin to quantify the significant effects that both human-made and natural ponds have on the global greenhouse gas budget, measurements that aren’t well understood. “Global climate models and predictions rely on accurate accounting of greenhouse gas emissions and carbon storage,” said Meredith Holgerson, assistant professor of ecology and evolutionary biology at Cornell and senior ...

New research by Janelia scientists and collaborators at the University of North Carolina at Chapel Hill shows how a cluster of neurons in the fruit fly brain transforms memories about past rewards into actions, helping the fly navigate to find food. Like other insects, flies turn into the wind, or upwind, to locate the source of attractive odors. The fly’s olfactory system detects and senses odors carried by the wind, guiding the fly to the reward. In the fly, a brain region called the mushroom body processes and integrates olfactory information. Multiple compartments ...
