The recent research led by an Indian-origin researcher has offered a ray of hope in the dark cloud of HIV. Sudhir Paul claims that his team has found that this weak spot known as amino acids numbered 421-433 on gp120, is hidden in the HIV envelope protein gp120. This protein is essential for HIV attachment to host cells, which initiate infection and eventually lead to Acquired Immunodeficiency Syndrome or AIDS.

A research led by Professor Joanne Aitken, from the Cancer Council Queensland showed that the regular skin checks can 'cut deadly melanoma risk'. The researchers proved that a quick body scan cuts the risk of a deadly melanoma diagnosis by about 15 per cent. The basic logic behind this claim was that a regular body screening by doctors can detect the melanoma in the early stages. Hence it could be cured before it reaches its deadly stages.

The researchers analyzed the data collected from more than 3,000 Queenslanders. These people were diagnosed with one of the dangerous skin lesions. The researchers studied the relationship between skin checks and the severity of the spot.

The latest research done by Canadian and European researchers can help many childless couples .The researchers have discovered a gene that regulates ovulation; a gene known as  LRH1 that has ability to both regulate and block ovulation. This discovery could be useful in arenas of infertility treatment on one hand while on the other hand it could be used to produce safer contraceptives.
 
Under this study, a genetically engineered mouse that had its LRH1 gene blocked was mated with female mice. The female mice didn’t get pregnant, hence this proved that by blocking LRH1, ovulation can be stopped.

The doctors in Britain have to prove their fitness once in five years to carry on their practice. This plan is introduced by England's Chief Medical Officer Liam Donaldson on Wednesday. The current plan is the biggest change in medical regulations of UK for 150 years.

The report presented by the House of Lords claimed that a threat of pandemic is looming over Britain.

The report said, "Estimates are that the next pandemic will kill between two million and 50 million people worldwide and between 50,000 and 75,000 in the UK. Socio-economic disruption will be massive."

The report further added that changes in lifestyle are supplementary to such infections.  The report mentioned various diseases like Malaria and TB which are developing resistance to the antibiotics. The report also presented concern over the various diseases that are now transmitted from animals to humans.

Wrinkles are concerns of most of the people. Most people don’t like their youthful spirit to be disarmed by the wrinkles of the old age. Every year millions of men and women spend large amount of money on the treatment of wrinkles.

According to the research of P. Daniel Ward, and Shan R. Baker from the University of Michigan carbon dioxide (CO2) can help in reducing wrinkles. The study showed that the CO2 laser vaporizes water molecules inside and outside cells, causing thermal damage to the surrounding tissue. Then the skin produces more of the protein collagen, filling in the wrinkles. The researchers said,
