Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Researchers report novel charge zipper principle used by proteins to form functional units

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane.

Link between air pollution and people's happiness

Researchers in Canada have found a correlation between air pollution and people's happiness. Their deep analysis, reported in the latest issue of the International Journal of Green Economics, suggests that air pollution may lead to unhappiness while the converse is also true, the unhappier the citizens of a country the more air pollution.

Scientists compare neuronal network connections in 2 worm species

Researchers in the group of Ralf Sommer at the Max Planck Institute for Developmental Biology in Tuebingen, Germany, have for the first time been able to identify neuronal correlates of behaviour by comparing maps of synaptic connectivity, or "connectomes", between two species with different behaviour.

Macular pigment screening: an interview with Jaquie Finn, Product Line Manager at Elektron Technology

AMD is the leading cause of vision loss in anyone over 50 and globally in 2010 it was estimated to cost $340 billion to treat AMD. The costs are set to spiral over the next 20 years and really over burden the healthcare system unless people start to take preventative action.

Race bias decreases similarities in the brain's representations of faces

Racial stereotypes have been shown to have subtle and unintended consequences on how we treat members of different race groups. According to new research published in Psychological Science, a journal of the Association for Psychological Science, race bias also increases differences in the brain's representations of faces.

Degree of emphysema predicts mortality in ever-smokers with or without COPD

Severity of emphysema, as measured by computed tomography (CT), is a strong independent predictor of all-cause, cardiovascular, and respiratory mortality in ever-smokers with or without chronic obstructive pulmonary disease (COPD), according to a study from researchers in Norway. In patients with severe emphysema, airway wall thickness is also associated with mortality from respiratory causes.

UC Riverside research: Exercise-loving mice have larger midbrains

Is athleticism linked to brain size? To find out, researchers at the University of California, Riverside performed laboratory experiments on house mice and found that mice that have been bred for dozens of generations to be more exercise-loving have larger midbrains than those that have not been selectively bred this way.

Simple interventions can reduce amputations in diabetic patients by more than 50%

Every 30 seconds somebody in the world is amputated as a consequence of foot complication due to diabetes. A new study at Sahlgrenska Academy, University of Gothenburg, Sweden, confirmes that shoe inserts, podiatry, regular checkups and other simple interventions can reduce the number of amputations by more than 50%.

Atrial fibrillation increases risk of kidney failure in people with CKD

Many people who suffer from chronic kidney disease progressively lose their kidney function over time and eventually develop a condition called end-stage renal disease - the complete failure of the kidneys - placing them in need of lifelong dialysis or a kidney transplant.
