Researchers develop paper-thin device to test cholesterol levels

Paper-thin sensors that use the latest technology in miniaturisation and printing could revolutionise the way point of care testing is carried out for cholesterol and lead to further applications and developments of the technology.



Variations cause high triglyceride levels in blood

A recent study has shown that it's a combination of both common and rare variants or 'misprints' in several genes that add up and put a patient at risk of developing HTG.



Oil spills raise arsenic levels in the ocean

Oil spills can increase levels of toxic arsenic in the ocean, creating an additional long-term threat to the marine ecosystem, according to research published today in the journal Water Research.



Lowering homocysteine levels with folic acid

Patients who had experienced a heart attack and lowered their blood homocysteine levels with folic acid and vitamin B12 supplementation did not have an associated lower risk of heart attack, coronary death or stroke, according to a study.



CO2 levels explain temperature fluctuations

Increasingly, the Earth's climate appears to be more connected than anyone would have imagined. El Niño can spawn heat waves and droughts as far away as Africa.



Greater environmental protection from monitoring lower levels of contaminants

Next generation calibration gas mixtures are essential to enable new air quality analysis technologies. Stephen Harrison reports.



SIDS linked to low levels of serotonin

The brains of infants who die of sudden infant death syndrome produce low levels of serotonin, a brain chemical that conveys messages between cells and plays a vital role in regulating breathing, heart rate, and sleep, reported researchers.



Glucose levels may affect decision making

Studies have indicated that there may be a link between blood glucose levels (our body's energy) and thinking.



Untold levels of oil sands pollution

After an exhaustive study of air and water pollution along the Athabasca River, researchers say pollution levels have increased as a direct result of nearby oil sands operations.



Postmenopausal women with higher testosterone levels

Postmenopausal women who have higher testosterone levels may be at greater risk of heart disease, insulin resistance and the metabolic syndrome compared to women with lower testosterone levels.



CO2 levels at 15 million year high

By analysing the chemistry of bubbles of ancient air trapped in Antarctic ice, scientists have been able to determine the composition of Earth's atmosphere going back as far as 800,000 years.



Lungs labour at acceptable ozone levels

Ozone exposure, even at levels deemed safe by current clean air standards, can have a significant and negative effect on lung function, according to researchers at the University of California Davis.



High levels of fructose impairs memory

Researchers at Georgia State University have found that diets high in fructose - a type of sugar found in most processed foods and beverages - impaired the spatial memory of adult rats.



Vitamin D levels linked to asthma severity

Serum levels of vitamin D were inversely linked to several indicators of allergy and asthma severity, including hospitalisations for asthma, use of inhaled steroids and total IgE levels.



Increasing levels of rare element

Dartmouth researchers have determined that the presence of the rare element osmium is on the rise globally and trace this increase to the consumption of refined platinum.



Autism linked with stress hormone levels

Some of the symptoms of the autistic condition Asperger Syndrome, such as a need for routine and resistance to change, could be linked to levels of the stress hormone cortisol.



Micro-RNA levels

A new study suggests that a type of acute leukaemia may occur in part because abnormally low levels of one small molecule result in the over-activity of genes important to the disease.



Allergen levels and asthma

Results from a new survey demonstrate that elevated allergen levels in the home are associated with asthma symptoms in allergic individuals.



Controlling bacteria levels in pure water

Dr Paul Whitehead looks at effective systems for controlling the problem of bacterial levels in pure water for laboratories.



Limiting polyunsaturated fatty acid levels in pregnancy may influence body fat of children

Southampton researchers have demonstrated that mothers who have higher levels of n-6 polyunsaturated fatty acids (PUFAs), which are found in cooking oils and nuts, during pregnancy have fatter children.
