Rutgers Universtiy develops a "lab on a chip"
September 12, 2015 08:12 AM - Rutgers University
Rutgers engineers have developed a breakthrough device that can significantly reduce the cost of sophisticated lab tests for medical disorders and diseases, such as HIV, Lyme disease and syphilis.
The new device uses miniaturized channels and valves to replace “benchtop” assays – tests that require large samples of blood or other fluids and expensive chemicals that lab technicians manually mix in trays of tubes or plastic plates with cup-like depressions.
“The main advantage is cost – these assays are done in labs and clinics everywhere,” said Mehdi Ghodbane, who earned his doctorate in biomedical engineering at Rutgers and now works in biopharmaceutical research and development at GlaxoSmithKline.
Coastal management strategies in the age of climate change
September 4, 2015 05:52 AM - ClickGreen staff, ClickGreen
Coastal decision-makers must move away from considering physical and economic forces in isolation to fully recognise and explain changes to coastlines, according to new research from Cardiff University.
The coastlines where we live, work and play have long been altered by people, but now researchers have investigated why developed coastlines change over time in ways that are fundamentally different from their undeveloped, natural counterparts.
Food's impact on our brain found to be similar to drugs
August 31, 2015 07:58 AM - EUROPEAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY via EurekAlert
An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be 'hard-wired' into the brain of overweight patients, becoming a functional brain biomarker.
Obesity is one of the most difficult problems facing modern society. Treating obesity is a health priority, but most efforts (aside from bariatric surgery) have met with little success. In part, this is because the mechanisms associated with the desire to eat are poorly understood. Recently, studies are beginning to suggest that the brain mechanisms underlying obesity may be similar to those in substance addiction, and that treatment methodologies may be approached in the same way as other substance addictions, such as alcohol or drug addiction.
Even safe levels of air pollution found to have health impacts in European study
August 30, 2015 07:40 AM - EUROPEAN SOCIETY OF CARDIOLOGY via EurekAlert
Particulate matter and NO2 air pollution are associated with increased risk of severe heart attacks despite being within European recommended levels, according to research presented at ESC Congress today by Dr Jean-Francois Argacha, a cardiologist at University Hospital Brussels (UZ Brussel-Vrije Universiteit Brussel), in Belgium.1
"Dramatic health consequences of air pollution were first described in Belgium in 1930 after the Meuse Valley fog," said Dr Argacha. "Nowadays, the World Health Organization (WHO) considers air pollution as one of the largest avoidable causes of mortality. Besides the pulmonary and carcinogenic effects of air pollution, exposition to air pollution has been associated with an increased risk in cardiovascular mortality."
NASA's latest satellite data reveals global sea level rise
August 27, 2015 08:49 AM - ClickGreen Staff, ClickGreen
Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.
Plastic particles found in cosmetics
August 26, 2015 10:12 AM - Plymouth University
Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a millimetre in diameter – could be released in every single application of certain products, such as facial scrubs.
More American shoppers becoming "locavores"
August 24, 2015 08:37 AM - ClickGreen Staff, ClickGreen
More Americans than ever before are supporting their local food markets, and new research has found it's not just because they believe the food is fresher and tastes better.
The Fukushima Accident Lives On
August 18, 2015 12:14 PM - Dr Ian Fairlie, The Ecologist
New evidence from Fukushima shows that as many as 2,000 people have died from necessary evacuations, writes Ian Fairlie, while another 5,000 will die from cancer. Future assessments of fatalities from nuclear disasters must include deaths from displacement-induced ill-heath and suicide in addition to those from direct radiation impacts.
Neighborhood electric vehicles
August 17, 2015 07:23 AM - BOB SHETH, Electric Forum
While much of the focus of late has been upon mainstream electric vehicles it seems as though the popularity of Neighborhood electric vehicles continues to grow. These vehicles have a history which is far more successful than there larger electric vehicle counterparts but receive very little in the way publicity or promotion. The Global Electric Motor (GEM) brand is by far and away the best known brand in this particular sector having changed hands on numerous occasions in the past.
So, why is it that NEVs continue to sneak under the radar yet gain in popularity?
Men's and women's brains do work differently
August 13, 2015 07:20 AM - Editor ENN
Male and female brains operate differently at a molecular level, a Northwestern University research team reports in a new study of a brain region involved in learning and memory, responses to stress and epilepsy.
Many brain disorders vary between the sexes, but how biology and culture contribute to these differences has been unclear. Now Northwestern neuroscientists have found an intrinsic biological difference between males and females in the molecular regulation of synapses in the hippocampus. This provides a scientific reason to believe that female and male brains may respond differently to drugs targeting certain synaptic pathways.
