A brain imaging study shows that patients with chronic fatigue syndrome may have reduced responses, compared with healthy controls, in a region of the brain connected with fatigue. The findings suggest that chronic fatigue syndrome is associated with changes in the brain involving brain circuits that regulate motor activity and motivation.

Compared with healthy controls, patients with chronic fatigue syndrome had less activation of the basal ganglia, as measured by fMRI (functional magnetic resonance imaging). This reduction of basal ganglia activity was also linked with the severity of fatigue symptoms.

A new chemotherapy drug being investigated for its potency against two types of cancer was found by scientists at Houston Methodist and seven other institutions to be effective in about one-third of the 58 patients who participated in a phase I study.

The drug, alisertib or MLN8237, inhibits the enzyme aurora A kinase, which is known to be very active during cell division. The present study, published in the journal Investigational New Drugs, looks at the safety, tolerability, and preliminary success of alisertib in treating non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL).

University of Adelaide research has for the first time confirmed that women who eat a poor diet before they become pregnant are around 50% more likely to have a preterm birth than those on a healthy diet.

Researchers at the University of Adelaide's Robinson Research Institute investigated the dietary patterns of more than 300 South Australian women to better understand their eating habits before pregnancy.

It's the first study of its kind to assess women's diet prior to conception and its association with outcomes at birth.

Research from North Carolina State University finds that a lack of plant diversity is a key contributor to the widespread defoliation caused by cankerworms in cities, and highlights the role that increasing diversity can play in limiting future damage.

Fall cankerworms (Alsophila pometaria) are caterpillars that are native to the eastern United States and hatch in early spring. The cankerworms defoliate trees and other plants, eating new leaves as they emerge – which is both unsightly and can ultimately kill the plants.

Word-of-mouth marketing is recognized as a powerful route from long-tail sales to blockbuster and in the age of social media and online networking sites such as Twitter and Facebook, spreading the word could mean the difference between consumers seeing a product as the best thing since sliced bread or the most rotten of tomatoes.

Bright yellow fields of oilseed rape are a common sight at this time of year but what lies beneath is a lot more exciting.

Straw from crops such as wheat, barley, oats and oilseed rape is seen as a potential source of biomass for second generation biofuel production. Currently the UK produces around 12 million tons of straw and much of it is used for animal bedding, mushroom compost and energy generation but there still exists a vast surplus.
