Birth Control Linked to Increased Breast Cancer Risk.
In one of the largest studies of its kind, researchers found that birth control interventions relying on the release and regulation of hormones was linked to a statistically significant increase in breast cancer. The study followed more than 1.8 million Danish women for over 10 years, finding that for every 100,000 women receiving hormonal birth control measures, there were 68 cases of breast cancer annually - that compares with 55 cases for nonusers. Longer use led to higher risk, from a 9% increase in risk with less than a year of use to a 38% increase in risk after 10 years of use. In terms of absolute numbers the increased risk is small, amounting to one new case for every 7,770 women that use such contraceptives.

Mystery Da Vinci Buyer Revealed.
A little known Saudi prince was revealed to be the buyer of a rare Leonardo da Vinci painting at an auction last month. At the time, the record-breaking sales tag of $450.3M made a splash - but the news that Bader bin Abdullah bin Mohammed bin Farhan al-Saud, who has no publicly known source of great wealth, raised eyebrows. In addition to it being an un-Islamic painting of Christ, the purchase comes amid a political purge by the country's crown prince.
