The bluegill on your dinner plate might have been more social than the rest of its group, according to a new study from the University of Illinois, and its removal from the lake could mean major changes for the remaining population.
Our cells communicate with each other and with the environment using tiny antennae, called cilia. Some of these antennae can also move, and are altered in several diseases. A team from the Gulbenkian Institute of Science has now discovered that the foundation of cilia is diverse, contributing to the assembly of antennae with such different functions. This study, now published in Nature Cell Biology, will help physicians better understand diseases called ciliopathies
According to a new National Institutes of Health-funded study, it is not destiny that brings two fruit flies together, but an evolutionary matchmaker of sorts that made tiny adjustments to their brains' mating circuits, so they would be attracted to one another while rejecting advances from other, even closely-related, species. The results, published in Nature, may help explain how a specific female scent triggers completely different responses in different male flies.
An independent inquiry by the Nuffield Council on Bioethics has concluded that editing the DNA of a human embryo, sperm, or egg to influence the characteristics of a future person ('heritable genome editing') could be morally permissible. If that is to happen, a number of measures would need to be put in place first to ensure that genome editing proceeds in ways that are ethically acceptable.
Fossils come in many shapes and sizes, ranging from isolated fragments of bones and teeth to complete skeletons.
Particulate matter deposits on leaves increase plant transpiration and the risk of plants suffering from drought. Particulate matter could thus be contributing more strongly to tree mortality and forest decline than previously assumed. This is suggested by results from a greenhouse study led by the university of Bonn, in which tree seedlings grown in almost particulate matter free air or in unfiltered air were compared. The results are now being published in "Environmental Research Letters".
Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure.
Preventing reservoir evaporation during droughts with floating balls may not help conserve water overall, due to the water needed to make the balls.
It was previously thought that the T cell would concentrate the receptors at certain points in order to achieve the highest possible sensitivity. As a current publication by the biophysics research group at TU Wien shows, T cells are actually programmed to react as quickly as possible, and therefore their receptors are arranged at random.
The estimates for global tuberculosis deaths by the World Health Organisation (WHO) and the Institute for Health Metrics and Evaluation (IHME) differ considerably for a dozen countries, according to a study led by ISGlobal. The results highlight the need to improve the modeling approaches in these countries in order to understand the true burden of the disease and design adequate health policies.
