"Sea stars were assumed to be at the mercy of the sun during low tide," said the study's lead author, Sylvain Pincebourde of François Rabelais University in Tours, France. "This wo...
Studies and Analyses |The war between the sexes has been fought on many fronts throughout time—from humans to birds to insects, the animal kingdom is replete with species involved in their own skirmishes. A recent ...
Life Sciences |An important, ground-breaking initiative is unfolding in the global critical care community in response to the H1N1 pandemic.While front-line health care workers and infectious disease experts...
Life Sciences |Organisms ensure the survival of their species by genetically adapting to the environment. If environmental conditions change too rapidly, the extinction of a species may be the consequence. A strateg...
Life Sciences |Historically, many people, including marine scientists, have considered the abyssal plains, more than 2,000 meters below the sea surface, to be relatively isolated and stable ecosystems. Howev...
Ecology, The Environment and Conservation |While sedentary lifestyles and diets high in sugar and fat contribute significantly to the rise in diabetes rates, genetic factors may make some people more vulnerable than others to developing diabet...
Life Sciences |Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE),...
Earth Sciences |Now an international constellation of research teams, including one at the Swedish University of Agricultural Sciences, has shown that parts of the genetic programs that determine programmed cell deat...
Life Sciences |The researchers determined that the flatworm group Acoelomorpha is a product of the deepest split within the bilateral creatures — multicelled organisms that, like humans, have symmetrical body forms....
Information Technology |Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of con...
Ecology, The Environment and Conservation |A reaction similar to the inactivation of prostaglandin hormones in animals has now been discovered in the larval guts of two plant pest species. The insects bear an enzyme which structurally modifies...
Life Sciences |Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. A team from the University of Exeter has found tha...
Ecology, The Environment and Conservation |Researchers at and associated with the International AIDS Vaccine Initiative (IAVI), at The Scripps Research Institute, and at the biotechnology companies Theraclone Sciences and Monogram Biosciences ...
Life Sciences |Why is it that you can instantly recall your own phone number but have to struggle with your mental Rolodex to remember a new number you heard a few moments ago? The two tasks "feel" differe...
Life Sciences |A team of scientists from the California Institute of Technology (Caltech) have pinpointed two groups of neurons in fruit fly brains that have the ability to sense and manipulate the fly's fat st...
