Longer sleep linked to stroke
Conclusion
This cohort study found that, overall, people who sleep for more than eight hours have a 46% increased risk of stroke. When analysed separately, there was no statistically significant association for men, but a much higher increased risk for women, of 80%.
A major strength of the study is the number of potential confounding factors that the researchers tried to account for, including many cardiovascular risk factors. However, it did not account for other illnesses such as sleep apnoea or cancer, which may have had an effect on the amount of sleep and risk of stroke.
In addition, the study is reliant on the i...

The increasing burden of atrial fibrillation in acute medical admissions, an opportunity to optimise stroke prevention.
Conclusions Atrial fibrillation prevalence is significantly increasing among acute hospital admissions; these patients have high risk of cardioembolic stroke. Careful screening and identification in secondary care can lead to improved rates of anticoagulation.

Moderate drinking may reduce heart disease risk
Conclusion
This study paints a more complicated picture than the "Pint a day keeps the doctor away" story proffered by The Sun.
It seems to confirm the findings of other studies, which have shown that non-drinkers tend to have a higher risk of cardiovascular diseases than people who drink moderately.
It suggests that some cardiovascular diseases (mainly those directly affecting the heart) seem to have a stronger link to a possible protective effect from alcohol than other vascular diseases, such as mini-strokes and bleeding in the brain. However, this can't be concluded with certainty due to the study design.
We ...

Tomato extract effects exaggerated
ConclusionThis study found that the blood vessels in people with cardiovascular disease who were taking statins dilated more after they were treated with a chemical called acetylcholine if they had been taking lycopene every day for two months, compared to those taking placebo pills.The lycopene tablet had no significant effect on any of the other outcomes the researchers looked at, and no effect in healthy volunteers, although it did increase lycopene levels in the blood. Although impaired endothelial function is a known predictor of future heart disease, this is, at best, a surrogate outcome. It is no substitute for fo...

Inactivity 'twice as deadly' as obesity
Conclusion
This study’s strengths included its large size and long follow-up period. Researchers also took into account a large number of factors (called confounders) that might have influenced the risk of death, such as diet, smoking history and alcohol intake, although it is still possible that both measured and unmeasured confounders influenced mortality rates.
The study had one important limitation. It only measured people’s BMI (calculated by combining their weight and height) and their physical activity once, at the start of the study. It is quite possible that people’s BMI changed over time, and that this wou...

Morphological and Whole-Word Semantic Processing Are Distinct: Event Related Potentials Evidence From Spoken Word Recognition in Chinese
In conclusion, the present study provides electrophysiological evidence of the dissociation of morphological and whole-word semantic processing in Chinese spoken word processing. The results identified a central-anterior morphological N400 effect when morphemic meaning conflicts with whole-word semantics, in addition to a classic semantic N400 effect with significantly reduced amplitude in central-parietal areas. Our results also showed that the morphological N400 effect is negatively correlated with reading ability. These results demonstrate the important role of morphological processing in Chinese spoken word recognition...

A Current Amplifier For Local Coil Pre-amplification Of NMR/MRI Signals
A Current Amplifier for Local Coil Pre-amplification of NMR/MRI SignalsDescription of Technology:
The magnetic resonance imaging (MRI) systems are used for a variety of imaging application. The present invention discloses an improving MRI device and method by amplifying signals received by resonant NMR coils of MRI systems. It utilizes positive feedback from low-noise Field-Effect Transistor to amplify the signal current that can be coupled out to receiving loops positioned externally without loss in sensitivity. Therefore, the NMR coil can be flexibly positioned near internal tissues and used to develop high-resolution im...

Joe Farman obituary
Scientist whose discovery of the depletion of the ozone layer sparked global action to phase out dangerous chemicalsJoe Farman, who has died aged 82, was the leader of a small group of scientists who made one of the most important discoveries in recent history. In 1985, they published a landmark paper on the ozone layer, the protective skin that filters the sun's ultraviolet rays and without which the rays can cause cancers and eye damage. Their research showed that the ozone layer was being rapidly depleted over the Antarctic.Just two years later, world governments signed the Montreal protocol, a treaty phasing out the us...
