New research has uncovered deep secrets hidden within the mystery of academic sibling rivalry. First borns were significantly more conscientious and also more dutiful than younger siblings. Last born siblings were more likely to feel academic rivalry compared to first borns.

To date, there are two basic concepts of reasons for ageing. The first one is death as a result of damage accumulation, and the second is death as a suicide program. There are multiple arguments in favour of both concepts.

Scientists in Portugal and Germany report of research that suggest a new therapy to control the spread of tumour cells to new tissues, a process known as metastasis and that is associated with high risk of a fatal outcome. The research describes how the chaotic, increased motility of some tumour cells, known to be crucial for metastases, can be linked to the aberrant activation of a molecule called epidermal growth factor receptor (EGFR). It also shows how inhibition of this activation reverts high motile cells into a normal benign pattern of motility. The research suggests that EGFR inhibitors, which are readily available in the market, could be a potential new therapy in the control of metastases in some type tumours.

Administration of a quadrivalent human papillomavirus (HPV) vaccine has proven effective in preventing high-grade vulval and vaginal lesions that can lead to cancers in those areas, conclude authors of a study published in The Lancet.
