Gang warfare is not unique to humans -- banded mongooses do it too. Now researchers from the University of Exeter have shed light on the causes of the fights -- and found they are most common when females are receptive to breeding and when there is competition over food and territory.
A task force commissioned in 2016 by former U.S. Secretary of Energy Ernest Moniz has proposed a framework for evaluating R&D on recycling carbon dioxide and removing large amounts of CO2 from the atmosphere. The goal is to produce a global emissions reduction of at least 1 billion tons of CO2 per year.
Some fruit flies build up tolerance to the toxin alpha-amanitin; the genetic mechanisms behind this adaptation link to an important metabolic pathway. A team from Michigan Technological University used genome-wide association mapping to draw the connections for 180 fruit fly lines.
Fossil hunters have found part of an ancient primate jawbone related to lemurs -- the primitive primate group distantly connected to monkeys, apes and humans, a USC researcher said. Scientists named the new species Ramadapis sahnii and said that it existed 11 to 14 million years ago. It is a member of the ancient Sivaladapidae primate family, consumed leaves and was about the size of a house cat.
Light beamed into a patient's blood through an optical fiber can determine whether blood is clotting during an operation, continuously and in real time. Researchers believe it could take the place of traditional blood tests in some situations and have myriad healthcare applications.
A team of MIT biological engineers has developed a method to measure levels of heme, a critical iron-containing molecule, inside the parasite that causes malaria. This could eventually help scientists develop better drugs to combat the disease.
A new study suggests that civic engagement, in the form of community-based 'Change Clubs,' engages Black/African American women to address nutrition and exercise concerns in their community and motivates them to change their individual behaviors, which may improve heart health.
New light on a key factor involved in diseases such as Parkinson's disease, gastric cancer and melanoma has been cast through latest University of Otago, New Zealand, research carried out in collaboration with Australian scientists.
An invasive species of marsh grass that spreads, kudzu-like, throughout North American wetlands, may provide similar benefits to protected wetlands as native marsh grasses. According to new research from North Carolina State University, the invasive marsh grass's effects on carbon storage, erosion prevention and plant diversity in protected wetlands are neutral.
Does a name in itself have sufficient symbolic power to cause a paradigm shift in how humans perceive our role in the changing geological patterns of the planet? That is among the questions with which David Casagrande, associate professor of anthropology at Lehigh University and his colleagues grapple in their latest article in Anthropology Today: 'Ecomyopia in the Anthropocene.'
