Many patients with advanced, incurable cancer do not receive any palliative care, reveals new research to be presented later this month at the ESMO 2014 Congress in Madrid, Spain, 26-30 September. The findings are astonishing as they come at the same time as 15 new oncology centres in Europe, Canada, South America and Africa are being awarded the prestigious title of 'ESMO Designated Centre of Integrated Oncology and Palliative Care.'

There is nothing inherently superior about natural gas from hydraulic fracturing - fracking - it has the same emissions as regular natural gas. But it is a lot lower than coal and does not have the political baggage of nuclear energy and that is why environmentalists lobbied for it over the last 40 years.

Leguminous plants are able to grow well in infertile land, and bear many beans that are important to humans. The reason for this is because most legumes have a symbiotic relationship with bacteria, called rhizobia, that can fix nitrogen in the air and then supply the host plant with ammonia as a nutrient.

The plants create symbiotic organs called nodules in their roots. However, if too many root nodules are made it will adversely affect the growth of the plants, because the energy cost of maintaining excessive nodules is too large. Therefore legumes must have a mechanism to maintain the proper number of root nodules, but this system has been poorly understood.

Japanese researchers showed monkeys a number of images representing various glosses and then they measured the responses of 39 neurons by using microelectrodes. They found that a specific population of neurons changed the intensities of the responses linearly according to either the contrast-of-highlight, sharpness-of-highlight, or brightness of the object. This shows that these 3 perceptual parameters are used as parameters when the brain recognizes a variety of glosses. They also found that different parameters are represented by different populations of neurons. This was published in the Journal of Neuroscience (September 4, 2014 issue).

An ultrasensitive biosensor made from the wonder material graphene has been used to detect molecules that indicate an increased risk of developing cancer.

The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a matter of minutes, opening up the possibility of a rapid, point-of-care diagnostic tool for patients.

The biosensor has been presented today, 19 September, in IOP Publishing's journal 2D Materials.

Taking daily supplements of selenium and/or vitamin E appears to have no significant effect on the development of age-related cataracts in men, according to new findings from the Selenium and Vitamin E Cancer Prevention Trial (SELECT) Eye Endpoints (SEE) Study.  

Some research, including animal studies, has suggested that dietary nutrients can have an effect on the onset and progression of cataracts. Vitamin E and selenium are of particular interest.
