Zika outbreak: The mosquito menace. Image copyright SPL This blood sucker might not be your best friend, but it loves you. The mosquito, Aedes aegypti, is causing widespread fear in Brazil where it is spreading the Zika virus that has been linked to thousands of babies being born with birth defects. So what do we know about it? It loves our cities This is not some jungle-dwelling insect that rarely comes into contact with people. It is one of those animals, like cockroaches, pigeons and urban foxes, that thrives in built-up areas. It does not need natural water sources to breed as it can lay eggs in the small and plentiful pools of stagnant water, such as gutters or flower pots, found in cities .

Image copyright Getty Images Cities like Singapore have big problems with the mosquito. Prof Uriel Kitron, from Emory University, said: "Aegypti is really adapted well for urban areas. "It is becoming more and more of an urbanised world and aegypti thrives - Brazil is an extreme example going from 20% to 80% urban in 70 years.

Human evolution 'not over yet' Image copyright Thinkstock The regular use of Caesarean sections is having an impact on human evolution, say scientists. More mothers now need surgery to deliver a baby due to their narrow pelvis size, according to a study. Researchers estimate cases where the baby cannot fit down the birth canal have increased from 30 in 1,000 in the 1960s to 36 in 1,000 births today. Historically, these genes would not have been passed from mother to child as both would have died in labour. Researchers in Austria say the trend is likely to continue, but not to the extent that non-surgical births will become obsolete. Dr Philipp Mitteroecker, of the department of theoretical biology at the University of Vienna, said there was a long standing question in the understanding of human evolution. "Why is the rate of birth problems, in particular what we call fetopelvic disproportion - basically that the baby doesn't fit through the maternal birth canal - why is this rate so high?

Image copyright Homeward Bound On Friday the largest ever all-female expedition to Antarctica is setting sail, hoping to increase the number of women in important scientific roles around the world, writes Ben Collins.

They call Ushuaia, a cold and windy port city in Argentina, the end of the world. It's from here that the largest ever all-female expedition to Antarctica will depart, with more than 70 women with backgrounds in science set to spend 20 days at sea. The voyage is part of the Homeward Bound initiative, an Australian programme aimed at increasing the representation of women in top science jobs across the globe.

"We're missing half the voice at the leadership table," says Dr Jessica Melbourne-Thomas, who along with entrepreneur and management expert Fabian Dattner, came up with the idea. The pair met during a leadership development course run by Dattner, and their frustration at the challenges faced by women in science quickly became a bold idea. Image copyright AFP.

RBS worst hit in Bank of England stress test. Image copyright Getty Images RBS has missed key hurdles in a Bank of England stress test, forcing it to devise new plans in case of a financial crisis. The toughest stress test yet measured the UK's seven biggest lenders against a global economic crash. RBS performed the worst and was forced to draw up a new capital plan, which has been accepted. The bank said it had "agreed a revised capital plan... to improve its stress resilience". It said the change came "in light of the various challenges and uncertainties facing both the bank and the wider economy highlighted by the concurrent stress testing process". 'Action taken' RBS, which is still 73% owned by the government after its bailout in 2008, submitted the new plan to the Bank of England (BoE) after running its own internal tests and finding its balance sheet would fall short.

Analysis: Simon Jack, BBC business editor Eight years on from the financial crisis and taxpayer-owned RBS is still short of the money it needs to survive another one.
