Grasses have "respiratory pores" (called stomata) that open and close to regulate the uptake of carbon dioxide for photosynthesis on the one hand and water loss through transpiration on the other.
Brain age is an MRI-derived estimate of brain tissue loss that has a similar pattern to aging-related atrophy. White matter hyperintensities (WMHs) are neuroimaging markers of small vessel disease and may represent subtle signs of brain compromise.
In a new study, Northwestern University researchers used artificial intelligence to analyze data from a wide variety of tissues, collected from humans, mice, rats and killifish. They discovered that the length of genes can explain most molecular-level changes that occur during aging.
A new study led by the University of Bonn has now discovered a mechanism that lets nerve cells autonomously regulate their sensitivity to incoming signals.
Researchers from the University of Pittsburgh have designed cancer-fighting nanoparticles that co-deliver a chemotherapy drug and a novel immunotherapy.
During a recent study researchers found that fruit flies can quickly compensate for catastrophic wing injuries while maintaining the same stability after losing up to 40 per cent of a wing.
Scientists have identified a drug that could be a game-changer for patients. Istradefylline, which is already approved for Parkinson's disease, could reduce not only the harmful effects of cisplatin but also improve its anti-tumour properties.
Understanding black holes is the key to unravelling the most fundamental laws governing the cosmos because they represent the limits of two of the best-tested theories of physics: the theory of general relativity, which describes gravity as resulting from the (large-scale) warping of space-t
A hydrologist in the IUPUI School of Science, Professor Lixin Wang, recently reviewed advances in the study of dryland productivity and examined major outstanding debates on dryland responses to environmental changes.
