The last time Annegret Raunigk gave birth, to her 13th child, she was 55 years old.
Now, the 65-year-old teacher from Germany is pregnant once again — this time with quadruplets conceived through in vitro fertilization, a German newspaper reported.
Critics have voiced concern that Raunigk purposefully sought out a high-risk pregnancy. “The 65-year-old body is definitely not designed to carry a pregnancy, not of one child and certainly not of quadruplets,” said Holger Stepan, head of obstetrics at the University of Leipzig
Pregnancies of women over the age of 45 are deemed high risk while “over 60 is naturally extreme.”
Raunigk could become the world’s oldest woman to give birth to quadruplets, but she wouldn’t be the oldest known woman to give birth.
Raunigk had her 13th child, Leila, in 2005. “I was surprised myself as the last baby wasn’t planned,” she said at the time, AFP reported. “I was told about it when I was 11 weeks pregnant.”
“At first, I only wanted one child,” she told Bild in 2005. “Not all were planned. But then things happen. I’m not a planner but rather spontaneous. And children keep me young.”
Raunigk, a Russian and English teacher nearing retirement, has children ranging in age from 9 to 44. She also has 7 garndchildren. She is expected to give birth to the quadruplets in two months, and AFP reports her pregnancy has been without any major complications so far.
Computers controlled by thought and other cutting edge developments have been named in a list of the top ten technologies which could shape our future
the complete article is here
The full list of the top ten emerging technologies:
Brain-computer interfaces: It is already possible to type just by monitoring the electrical activity of your brain, but as the technology advances, it could be possible for people with disabilities to operate wheelchairs using only their thoughts.
Mining metals from desalination brine: Large-scale desalination is becoming economically feasible for the first time because of new chemical processes that enable the mining of metals from waste water, or brine.
Nanostructured carbon composites: Cars made from carbon-fibre reinforced composites are as much as 40% lighter than older models, stronger, and more easy to recycle, offering the prospect for huge energy savings.
Grid-scale electricity storage: A fundamental breakthrough is close that would allow the saving of surplus energy from fluctuating renewable sources such as sun and wind within the electricity grid.
Body-adapted wearable electronics: Whether worn on the body, embedded in clothes or even under the skin, these devices can track information, such as heart rate and stress levels, giving people real-time feedback about their health.
Nanowire lithium-ion batteries: New batteries based on silicon – using tiny silicon nanowires – could have a longer life, charge more quickly and hold up to three times the power of existing batteries.
Screenless display: A 3D image projected into space – a “screenless display” – can convey information that a 2D image presented on a screen cannot, and is close to becoming a practical reality.
Human microbiome therapeutics: Drawing on knowledge gained from the Human Microbiome Project in 2012 and other research, human microbiome technology is increasingly seen as an important source of treatment for serious diseases as well as for improving health.
RNA-based therapeutics: RNA, like DNA, plays a part in protein synthesis and, to a lesser extent, the transmission of genetic information. Scientific advances are combining to enable a new generation of targeted, RNA-based drugs that could help find new treatments for cancer and infectious diseases
