Researchers from the Pakistan Institute of Community Ophthalmology in Peshawar, Pakistan, and the London School of Hygiene and Tropical Medicine in England conducted a survey of 16,600 adults 30 years of age of older. The study examined several factors in measuring the prevalence of blindness in Pakistan, the sixth most populous country in the world. These included age and socioeconomic indicators including education and household occupation.
The study showed that the prevalence of blindness was higher in women in every age category surveyed except those aged 30 to 39 years. After adjusting for age differences in the study sample, the odds of a woman being blind were 30 percent higher than for a man. The researchers theorize that lower utilization of eye care services as the result of barriers specific to women may explain this disparity.
In addition, the regions of Punjab and Balochistan were shown to have the highest incidence of blindness of Pakistan's four provinces. Of study participants 70 years or older, 76.9 percent were visually impaired. It is estimated that there are 1.14 million blind adults in Pakistan.
"This large population-based study, one of the few nationally representative studies worldwide, has reported the burden of blindness and visual impairment in this country and, most importantly, has revealed important gender and geographical differences," said Rupert Bourne, BSC, FRCOpth, MD, collaborating survey ophthalmologist from the International Centre for Eye Health, London, England. "Knowledge of these groups who are at risk and the barriers to uptake of eyecare should enable more effective and equitable targeting of resources. Data from the survey predicts an increase of blind individuals by 92 percent by the year 2020, which further emphasizes the importance of urgently improving the standard of eye care in this country."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
