The longstanding mystery surrounding Antarctica’s Blood Falls has finally been solved. The deep red falls were first discovered in Antarctica in 1911 where scientists noticed a river had stained the surrounding cliff of ice with a dark red color. Previously, they had believed it was due to algae discoloring the water, however that hypothesis was never verified.
Now, thanks to research by the University of Alaska Fairbanks, we know the true origin of the Blood Falls flowing from the Taylor Glacier. The deep red coloring is due to oxidized iron in brine saltwater, the same process that gives iron a dark red color when it rusts. When the iron bearing saltwater comes into contact with oxygen the iron undergoes oxidation and takes on a red coloring, in effect dying the water to a deep red color.
The research team calculates that the brine water takes approximately 1.5 million years to finally reach the Blood Falls as it makes its way through fissures and channels in the glacier.

Female historical figures who were happy with their choices
Greta Garbo
In the 1932 film “Grand Hotel,” Garbo’s character famously proclaimed, “I want to be alone,” a quote that was affiliated with her for the rest of her life. She did have several relationships, including a long on-and-off with her frequent co-star John Gilbert. He once proposed to her, but she said no. “I was in love with him, but I froze,” she later told New York magazine. “I was afraid he would tell me what to do and boss me. I always wanted to be the boss.”
Coco Chanel
The iconic designer had many, many love affairs and several significant relationships, but she never married. She was once quoted as saying, “I never wanted to weigh more heavily on a man than a bird.” Less great: the evidence that she worked as a Nazi spy during the Second World War.
Mary Cassatt
Cassatt had a lot of familial love, as she’s maybe best known for her paintings that clearly but unsentimentally depicted the bonds between parents and children. But that love came from her relationships with her nieces and nephews, as she chose not to marry and didn’t have kids herself. The Impressionist painter enjoyed the freedoms that feminism had given women of her privileged stature by the turn of the 20th century — among them the right to an independent life. She was highly educated and well-travelled, and spoke out about the importance of female suffrage.
Louisa May Alcott
Like Jo in her best-known book “Little Women,” Alcott was independent and concerned with advancing women’s place in the world. But unlike Jo, she never married. “I’d rather be a free spinster and paddle my own canoe,” she wrote in her journal.

Electric car revolution: calculating the cost of green motoring

Streets will be quieter, the air will be cleaner, people will spend less time at petrol stations and car factories might even return to Britain’s shores if the country switches to electric cars in a widespread fashion. But widespread adoption of battery-powered vehicles would not be without challenges too. A large-scale switchover to electric cars could create problems for power grids, could mean roads lined with charging poles and it could also leave a big hole in public coffers as fuel duty dries up.
With just over 90,000 fully electric and plug-in hybrid cars now on UK roads, such risks and benefits might look a way off. But this week big changes have been announced. On Wednesday Volvo said it will only launch electric or hybrid cars from 2019 and just a day later Emmanuel Macron’s new government pledged that France will ban diesel and petrol cars by 2040. Battery-powered travel could be coming far sooner than previously thought
According to research published this week by Bloomberg New Energy Finance the proportion of fully electric new cars sold in the UK will be one in 12 by 2030 – up from one in every 200 today. The surge in electric cars will have to be accompanied by thousands of new charging points to plug them all in. Today there are around 4,000 publicly accessible locations with 13,000 plug sockets. Of the 13,000, a fifth are so-called rapid charging connections that will top up a Nissan Leaf, the UK’s best-selling pure electric car, in half an hour.
The number of sockets is set to soar to 80,000 by 2025, predicts Zap-Map, which has mapped the ones built so far. There are 8,476 petrol filling stations across the UK, most with many pumps, but topping up takes minutes rather than hours. A lot of those will be installed in supermarkets, railway stations and car parks. But there will be also a lot of poles along residential streets, even though there are other innovative fixes such as the charging sockets a German company is building into street lamps.

Birth Plan Overhaul: Brazil hopes to reduce 85% C-Section rate and change public’s attitude toward natural births
C-sections can increase the risk of harm for both mother and baby.
Dana Dovey
July 8, 2015
Dr. Alexandre Sasaoka, an obstetrician working in an upscale maternity clinic in Sao Paulo, Brazil struggles to remember the last time he delivered a baby naturally. This is because Brazil has one of the highest rates of cesarean deliveries in the world, with some hospitals reporting 99 percent C-section. However, a new government initiative aims to shave down these high figures.
According to Brazil’s pro-natural birth initiative, doctors must now inform women about all the risks associated with C-section births and ask them to sign a consent form before performing the operation, the BBC reported. The new ruling also states that doctors must justify the reasoning behind their C-section before proceeding with the operation, and must fill in a complete record of how the labor and birth developed step by step. The government hopes the initiative will help to reduce the country’s exceptionally high C-section rate, something that Brazilian pediatrician Luciana Herrero described as an “international shame.”
The World Health Organization recommends that a nation’s cesarean section rate should not be higher than 10 to 15 percent, but many countries greatly surpass this recommendation. In the United States, around a third of all births are C-section, and in the UK, nearly one in four women chooses to deliver this way. However, despite the current trend in favor of C-section births, few nations can touch Brazil figures. Eighty-five percent of all births in Brazilian private hospitals are cesareans, and in public hospitals the figure is 45 percent, the BBC reported.
The reason for Brazil’s high caesarean birth rate is complicated. For one matter, booking a C-section beforehand ensures a new mother will have a hospital bed, a commodity that has become quite rare in the South American nation. Hospital beds are almost exclusively reserved for women undergoing C-sections, Newser reported. In addition, in Brazil, vaginal birth is considered taboo, since many women regard natural childbirth as “uncivilized and primitive.” In private hospitals, C-sections are seen as a status symbol, NPR reported. Unfortunately, money also seems to be one of the main drivers behind Brazil’s high C-section rate. Brazilian doctors get paid more to perform C-sections. They also report feeling more in control during C-sections and therefore more protected from litigation.
While C-sections are sometimes necessary, when done unnecessarily, they can pose a danger to both mother and baby. Generally, women who have C-sections take longer to recover from giving birth and report residual pain for longer when compared to women who deliver vaginally. And although risk of life-threatening complications from birth are rare, women who undergo C-sections are three times more likely to suffer from serious birth complications, such as severe bleeding, blood clots, and major infection when compared to women who give birth naturally, according to Consumer Reports.

Wearable tech for kids coming from LeapFrog
By Doug Gross, CNN
updated 12:57 PM EDT, Thu May 1, 2014
(CNN) – The wearable technology movement is in full effect, and exercise-based activity trackers lead the way. Now, it’s becoming child’s play.
LeapFrog, the maker of education-oriented tablets and apps for children, has unveiled1 LeapBand, a wearable activity tracker designed with kids in mind.
The band fits around the user’s wrist and looks a lot like a kids version of a smartwatch. By performing actions like “walk like a crab,” “spin like a helicopter” or “pop like popcorn,” kids can unlock new games and a group of Pokemon-like “digital pets” on the device.
The band connects to a website or app that lets parents monitor their children’s activities and choose which challenges they can select, and which they can’t.
Moving past smartphones and tablets, wearable tech has become arguably the hottest digital trend in the past year or so.
