Allergies and Asthma Possibly Linked to Female Hormones
Fluctuations in female sex hormones could play a role in the development of allergies and asthma, a major review of evidence suggests. Analysis of studies involving more than 500,000 women highlights a link between asthma symptoms and key life changes such as puberty and menopause. Further investigation could help explain why asthma is more common in boys than girls in childhood, but more common in teenage girls and women following puberty.

Infection Outbreaks at Hospitals Could be Reduced by Copper-Coated Uniforms
Doctors, nurses and healthcare professionals could soon be wearing uniforms brushed with tiny copper nanoparticles to reduce the spread of bacterial infections and viruses, such as Escherichia coli (E. coli), at hospitals. Material scientists have created a ‘durable and washable, concrete-like’ composite material made from antibacterial copper nanoparticles. They have also developed a way of binding the composite to wearable materials such as cotton and polyester, which has proved a stumbling block for scientists in the past.
