Researchers at the University of Warwick's Department of Chemistry have found a way of replacing the soap used to stabilize latex emulsion paints with nanotech sized clay armour that can create a much more hard wearing and fire resistant paint.
To date latex emulsion paints have relied on the addition of soaps or similar materials to overcome the polymer parts of the paint's aversion to water, stabilize the paint, and make it work. The University of Warwick chemistry researchers led by Dr Stefan Bon have found a simple way to individually coat the polymer particles used in such paints with a series of nanosized Laponite clay discs.
The discs effectively create an armoured layer on the individual polymer latex particles in the paint.

Nutraceuticals are used to create ‘functional foods’, the most commonly known of which are yogurts containing probiotic bacteria. However, many natural food products contain powerful ingredients that could be incorporated into food products to create functional foods.
Dr Nigel Brunton and Dr Hilde Wijngaard describe a number of possible new ingredients in the most recent issue of TResearch, Teagasc’s research magazine.
Waste Not, Want Not
Fruit and vegetable processing in Ireland generates substantial quantities of waste and by-products. However, researchers at Teagasc Ashtown Food Research Centre (AFRC) have found a potential use for this ‘waste’ as a source of antioxidants, which may help in the prevention of degenerative conditions such as cancer and heart disease.

6% of the patient population in Melbourne carries a genetic abnormality implicated in thalassemia. As well as causing blood disorders and severe mental retardation, boys with ATRX mutations have genital abnormalities. Our understanding of the genetic mutations which underlie this cluster of disorders has been advanced significantly by research performed by Dr. Anthony Argentaro.
Employing nuclear magnetic resonance while at Oxford and Cambridge Universities, he solved the three-dimensional structure of part of the huge ATRX protein that carries most of the clinical mutations. By comparing the structure of normal and mutated ATRX, he determined that too much OR too little ATRX leads to developmental disorders.

Alcoholism has traditionally been considered a male disease because there are many more alcoholic males than females.
But a new study by researchers at Oregon Health & Science University and the Portland Veterans Affairs Medical Center suggests that women are more prone to brain damage from alcohol abuse than men.
The study led by Kristine Wiren, Ph.D., associate professor of behavioral neuroscience and medicine, OHSU School of Medicine, and research biologist, PVAMC Research Service, found that female mice are more susceptible to neurotoxic effects of alcohol withdrawal, including significantly increased brain cell death, than male mice.

New research presented at Life Sciences 2007 shows how the UK’s most commonly used brominated flame retardant, TBBPA, bio-accumulates within the human body, meaning that even low concentrations could cause cells to become cancerous and have dramatic effects on sperm count and allergic responses.
Dr. Francesco Michelangeli explained exactly the process involved and called for research into alternative, less toxic, flame retardants.
The research is particularly significant as the use of a number of other flame retardants are being banned throughout Europe, due to their toxicity. TBBPA was considered the least toxic, and has, until now, been unaffected by bans. Brominated Flame Retardants (or BFRs) are known endocrine disrupters - ie.

High fructose corn syrup (HFCS) has been singled out as having special properties that make Americans fatter than sugar and other energy sources with identical calorie contents.
An analysis by the University of Maryland Center for Food, Nutrition, and Agriculture Policy (CFNAP ) says theres no evidence to conclude that high fructose corn syrup contributes to weight gain any more than any other energy source, such as sugar.
Instead, they say High fructose corn syrup has been targeted as a special suspect in causing obesity, in part because of timing and in part because of misunderstanding what it is.

Working mothers have it easier now than their own mothers did, at least with respect to childcare, a University of Leicester study has found.
The Labour government’s National Childcare Strategy, aimed at encouraging mothers to return to work, has simplified childcare, benefiting the younger generation of mothers, according to doctoral research by Dr Henrietta O’Connor in the University’s renowned Centre for Labour Market Studies.
In the course of the study, grandmothers and mothers in fourteen families were asked about their strategies for combining paid work and domestic responsibilities.

General Practitioners (GPs) are prescribing antibiotics for up to 80% of sore throat, otitis media, upper respiratory tract infections, and sinusitis cases, despite the fact that official guidance warns against this practice, according to an analysis of the world’s largest primary care database of consultations and prescriptions, published this week in a supplement to the Journal of Antimicrobial Chemotherapy.
Although prescriptions of antibiotics for respiratory tract infections declined during the 1990s, GPs still continue to prescribe antibiotics for a high proportion of infections even if the cause of the symptoms are likely to be viral.

Research now indicates that air pollution has a role to play in atherosclerosis (artery hardening), which can contribute to heart attacks or strokes. Findings published in Genome Biology show how the fats that clog arteries work together with air pollution particles, triggering the genes behind inflammation.
A research team drawn from medical and environmental engineering disciplines at the Universities of California, Los Angeles, investigated the relationship between oxidized phospholipids found in the low density lipoprotein (LDL) particles, the ‘bad’ fats that clog arteries, and diesel exhaust particles.

The "itch gene" is GRPR (gastrin-releasing peptide receptor), which codes for a receptor found in a very small population of spinal cord nerve cells where pain and itch signals are transmitted from the skin to the brain. The researchers, led by Zhou-Feng Chen, Ph.D., found that laboratory mice that lacked this gene scratched much less than their normal cage-mates when given itchy stimuli.
The laboratory experiments confirmed the connection between GRPR and itching, offering the first evidence of a receptor specific for the itch sensation in the central nervous system. The findings are reported this week in Nature through advance online publication.

The first threat is at the source of the raw material for nuclear power itself, the uranium mine, processing plant, and transport route. Here, physical protection and security are at a much lower level than at a nuclear installation in the developed world, according to Austrian scientists writing in today's issue of the International Journal of Nuclear Governance, Economy and Ecology.
The second threat is from saboteurs with expertise in the industry and the security of nuclear installations. Researchers from the US Environmental Protection Agency suggest that such saboteurs on the inside could wreak havoc and cause a serious environmental and health threats with only small, shaped explosives or even no explosives at all.

Public health officials have long sought to explain the dramatic rise in U.S. obesity rates. They considered the obvious factors like junk food and sedentary lifestyles but apparently forgot to consider your friends.
In the July 26 edition of the New England Journal of Medicine, researchers stated that obesity spreads through social ties. When an individual gains weight, it dramatically increases the chances that their friends, siblings, and spouses will likewise gain weight. The closer two people are in a social network, the stronger the effect. Interestingly, geographical distance between persons in a social network appears to have no effect.
So if you're reading this article, watch your waistline.
