Women may own the social sciences and education but they are under-represented in more math-intensive fields, according to a paper which looks at the US, EU, Brazil, South Africa, India, Korea and Indonesia.

Seven species of vulnerable sharks and manta rays have now been submitted by 35 countries for consideration for protection next year under an international treaty concerned with regulating wildlife trade.

Governments met the deadline today and formally submitted their proposals for the meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in March 2013. The recommendations include porbeagle and oceanic whitetip sharks, three species of hammerhead sharks, and two types of manta rays. For nearly 40 years, CITES has shielded thousands of plants and animals from overexploitation through international trade, and the treaty is widely considered one of the best-enforced international conservation agreements.

Online fundraisers taking part in organized events use social media to reach close to 600 people and inspire others to take on challenges for charity, according to new data from JustGiving.com

The U.S. Food and Drug Administration has granted Boston Scientific Corporation regulatory approval for its S-ICD(R) System, the world's first and only commercially available subcutaneous implantable defibrillator (S-ICD) for the treatment of patients at risk for sudden cardiac arrest (SCA).

Recent estimates show that approximately 850,000 people in the United States are at risk of SCA and indicated for an ICD device, but remain unprotected
