African medicinal plants contain chemicals that may be able to stop the spread of cancer cells. The plant materials will now undergo further analysis in order to evaluate their therapeutic potential.
The rate of suicide among men is almost three times that of women, according to new research. Being young, single and having a low level of education were stronger risk factor...
Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of be...
Common antidepressant medications may impair a form of learning that is important clinically. Selective serotonin reuptake inhibitors, commonly called SSRIs, are a class of antidepressant widely used to treat depression, as well as a range of anxiety disorders, but the effects of these drugs on learning and memory are poorly understood.
Researchers have proposed an answer to the long-running debate as to how stable the Earth system is. Earth, with its core-driven magnetic field, oceans of liquid water, dynami...
Canada's Mackenzie River basin -- among the world's most important major ecosystems -- is poorly studied, inadequately monitored, and at serious risk due to climate change and...
Helping to protect newborns and older patients against more severe effects of jaundice is the hope of researchers who have shown how a liver enzyme protects cells from damage caused by the condition. Their discovery might ultimately lead to an alternative treatment for jaundice, such as a new drug or supplement.
Delicious dimethyl sulphide. The microorganism Methanosarcina acetivorans lives off everything it can metabolize into methane. How it finds its sources of energy, is not yet clear. Scientists have now identified a protein that might act as a "food sensor."
Butterflies are extremely sensitive to changes in temperature, and new research has revealed that when summer weather turns bad the silver-spotted skipper battles for survival.
Detecting one individual biomolecule amongst millions of other neighboring molecules has been technically impossible until now. Scientists have now devised the smallest optical device capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context.
