Size of baby in womb as an indicator of childhood asthma and allergies

Children with asthma at five and 10 years had been 5mm or 10 per cent smaller than average as 10 week old embryos



Small pore size suits reduction of Mycoplasma in samples

Choosing the correct pore size to suit a specific application is an important consideration when choosing a filter



Brain function linked to birth size in new study

First evidence linking brain function variations between the left and right sides of the brain to size at birth and the weight of the placenta



Complete systems for large size bottles

A new range of containers from 15 to 40 litres targeting the food, water and beer market has been launched.



Exercise in pregnancy reduces size of offspring

According to a new study, regular moderate-intensity aerobic exercise led to a modest reduction in offspring birth weight without restricting the development of maternal insulin resistance.



Horizontal string trimmer increases peach size

As consumer demand for premium fruit increases, growers are being challenged to bring consistently high-quality fruit to market. And to boost their bottom line, orchard owners are experimenting with new techniques that can increase fruit quality while reducing labour costs.



Adult body size associated with cancer risk

A team of researchers has reported that body mass in younger and older adulthood, and weight gain between these life periods, may influence a man's risk for prostate cancer.



Biotechnology: Molecule that regulates heart size

Using zebrafish, researchers have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart.



Absolute Size Exclusion Chromatography

Size Exclusion Chromatography is a common technique in biochemistry laboratories and routinely used for purification, identification, and quantification of protein mixtures.



Measuring absolute molar mass and physical size of polymers

As the properties of a polymer can depend greatly on its size, there has always been a need to be able to measure it, both in terms of molar mass and physical size. The earliest polymers studied were materials such as elastomers and, later, synthetic polymers like polyethylenes or polypropylenes. The range of samples studied has since increased enormously with the realisation that many biological functions are also controlled by molar mass, size and shape.



Particle size analysis system

The new range of CPS Disc Centrifuges for particle size analysis consists of 4 models for use with various materials. These include polymer latexes (aqueous) with any particle density, emulsions of oils and waxes, titanium dioxide, photographic emulsions, abrasives, food ingredients and inorganic fillers and pigments.



High precision particle size distribution analyser

Polymer Laboratories has launched a new high precision particle size distribution analyser, the PL-PSDA, which uses the principle of particle fractionation.



Novel solution for particle size measurement problems

Work undertaken in Germany is demonstrating how a new particle size measurement technique is opening up many new applications areas in the laboratory. Heike Krischollek reports on the specific problems posed when dealing with biological materials and how one new measurement system has been designed to overcome these difficulties.



Shape and size matter when analysing food particles

It is vital that food manufacturers have a greater understanding of the influence of both particle shape and size on ingredient properties. Helen Metcalfe reports
