Ant-acacia plants attract ants by offering specialized food and hollow thorns in which the ants live, while the ant colony in turn defends its acacia against herbivores. This mutualistic relationship only occurs in older plants. New findings from University of Pennsylvania plant biologists, identify the genetic pathway that appears to regulate the timing of the acacia's ant-sustaining arsenal.
A new study in Evolution Letters finds that different bird species in the same challenging environment -- the highly saline ecosystem of tidal marshes along ocean shores -- were able to evolve unique species-specific ways to address the same problem.
If China takes strong measures to reduce its ozone pollution now, it could save hundreds of thousands of lives in the long run, according to a new study led by researchers at Columbia University's Lamont-Doherty Earth Observatory.
NASA's Aqua satellite passed over the Northwester Pacific Ocean after the sixth tropical depression formed. Tropical Depression Danas formed northeast of the Northern Philippines and was already affecting the country.
After Barry made landfall as a Category 1 hurricane, NASA's GPM core satellite analyzed the rate in which rain was falling throughout the storm. Now that Barry is a post-tropical cyclone moving through the mid-Mississippi Valley and toward the Ohio Valley, it is bringing some of that rainfall with it.
Researchers have discovered a new species of tree in the Usambara Mountains in Tanzania, part of the Eastern Arc Mountains, and a globally important region for species in need of conservation.
Over the past 22 years, sea levels in the Arctic have risen an average of 2.2 millimeters per year. This is the conclusion of a Danish-German research team after evaluating 1.5 billion radar measurements of various satellites using specially developed algorithms.
Biodiversity loss is one of the most prominent global issues, also affecting human well-being. With privately owned land covering large areas of the world, private land conservation is an increasingly recognized strategy to address the biodiversity crisis and support human well-being. A new study assessed 30 years of published scientific literature in order to identify research gaps and mainstream future private land conservation research.
Since the emergence of molecular genetics, scientists have tried to isolate haploid mammalian cells. Haploid cells are a powerful genetic tool to analyse gene function. In the past decade, a number of researchers finally succeeded in developing haploid cell line cultures. However, these cell lines are unstable and have a tendency for diploidisation. Now, researchers at the CNIO have identified chemical compounds that increase the stability of mammalian haploid cell lines.
La Trobe University researchers have uncovered an exception to the global phenomenon known as 'Insect Armageddon' in the largest study of Australian insect populations conducted to date.
