Scientists at the University of Stirling have discovered a new type of plant growing in Shetland -- with its evolution only having occurred in the last 200 years.
Researchers at NERF (VIB-imec-KU Leuven) have now uncovered striking neural activity patterns in a brain area called the retrosplenial cortex that may assist with spatial memory and navigation.
A new study from Lund University in Sweden increases knowledge of how boundaries and barriers are maintained between different species in the animal world. According to theory, crosses between two species, known as hybrids, may not survive encounters with natural predators to the same degree as their parents. Now, researchers at the Department of Biology in Lund show that reality confirms this theory.
Radioactive 129I has traveled the equivalent of a third of the way round the globe, since being released from nuclear fuel reprocessing plants in the UK and France. The iodine's 15,000 km journey begins in the nuclear plants at Sellafield and La Hague and continues via the Arctic Ocean and then southward via the Grand Banks towards Bermuda, where it is found at very low concentrations about 20 years later.
Researchers have developed a method to evaluate atmospheric conditions using mosses (bryophytes) in urban areas, a development that could facilitate broader evaluations of atmospheric environments.
One of the key questions in stem cell and cancer biology is to understand the cellular hierarchy governing tissue development and maintenance and the cancer cell of origin. In a study published in Cell Reports, researchers lead by Cédric Blanpain (Université libre de Bruxelles, Belgium) identified a novel lineage-restricted stem cell in the mammary gland. In the future, this model will be used to assess whether the clinical heterogeneity observed in breast cancers arises from their different cancer cell of origin.
A new data analysis technique, moving subtrajectory analysis, designed by researchers at Tokyo Institute of Technology, defines the dynamics and kinetics of key molecules in the immune response to an infection. These biophysical descriptions are expected to clarify the TCR microcluster, an essential assembly for a T cell to initiate its attack on a pathogen.
Novel insights into the genetic contribution to varying immune responses.
Women who have gone through menopause and who have been using a vaginal form of estrogen therapy do not have a higher risk of cardiovascular disease and cancer than women who have not been using any type of estrogen.
Vinegar flies should normally try to avoid their sick conspecifics to prevent becoming infected themselves. Nevertheless they are irresistibly attracted to the smell given off by sick flies. A dramatic increase in the production of the sex pheromones responsible for the attractive odor of the infected flies is caused by pathogens: this perfidious strategy is used by the deadly germs to enable them to infect healthy flies and spread even further.
