First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby. Transabdominal ultrasound involves scanning through your lower abdomen. A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel. The gel helps improve contact between the probe and your skin.
Can a dating scan be wrong by 4 weeks twins
Their study could force a reappraisal of when certain events occurred, notably in the period when modern humans lived alongside Neanderthals in Europe. It suggests that modern humans might have lived in Europe for longer than thought and that prehistoric paintings recently found in the Chauvet cave, in southern France, might be 38, years-old rather than the estimated 33, years.
An Anglo-American team found large variations in levels of the carbon isotope, used as the basis of carbon dating, preserved in a 19in stalagmite recovered from a submerged cave in the Blue Holes of the Bahamas, limestone caverns created when sea levels were nearly ft lower than today. These findings suggested dramatic changes in the amount of radioactive carbon in Earth’s atmosphere during the last Ice Age, much greater than previously thought, probably as a result of changes in the strength of the planet’s magnetic field.

Share this article Share But if the foetus or sac is not unusually small, for example if the sac is over 2cm, just one scan is done before the woman is told she has lost her baby. She then has the option of waiting to miscarry naturally, taking pills to induce the miscarriage or surgical removal. But experts say the 2cm cut-off point between having one scan and two is too risky.
A study of more than 1, British women estimated that around one in who are deemed to have miscarried because they have an apparently empty gestational sac of over 2cm will actually still be pregnant. These women would benefit from waiting for a second scan a week or so later that would be expected to reveal the foetus was alive. A further study revealed this figure could be much higher, as the measurements taken from the scans vary by as much as 20 per cent between medical staff.
Mistaken diagnoses in ultrasounds can be caused by misreading complex scans, old equipment and human error This means that the size of an apparently empty gestational sac could be overestimated, and miss the cut-off point for a second scan, increasing the possibility of the mother undergoing a wrongful termination. Mistaken diagnoses can be caused by difficulty in reading the complex scans, old equipment and simple human error.
The researchers said the precise numbers are unclear, but writing in the journal Ultrasound In Obstetrics And Gynecology sic , they estimated that errors could lead to women with healthy pregnancies being wrongly told their baby has died each year. It is not known how many of these will go on to have terminations but the figure of compares with cot deaths a year in the UK.

By Charlie Stross AI assisted porn video is, it seems, now a thing. For those of you who don’t read the links: You can then use the trained network to edit them, replacing one person in a video with a synthetic version of someone else. In this case, Rule 34 applies: The software runs on a high-end GPU and takes quite a while—hours to days—to do its stuff, but it’s out there and it’ll probably be available to rent as a cloud service running on obsolescent bitcoin-mining GPU racks in China by the end of next week.
But it’s going to get a whole lot worse. What I’m not seeing yet is the obvious application of this sort of deep learning to speech synthesis. It’s all very well to fake up a video of David Cameron fucking a goat, but without the bleating and mindless quackspeak it’s pretty obvious that it’s a fake. Being able to train a network to recognize the cadences of our target’s intonation, though, and then to modulate a different speaker’s words so they come out sounding right takes it into a whole new level of plausibility for human viewers, because we give credence to sensory inputs based on how consistent they are with our other senses.
We need AI to get the lip-sync right, in other words, before today’s simplistic AI-generated video porn turns really toxic. Hitler sums it up , now with fewer subtitles There are innocuous uses, of course. It’s a truism of the TV business that the camera adds ten kilograms. We can now automate the video-photoshopping of subjects so that, for example, folks like me don’t look as unattractive in a talking-heads TV interview.
Pretty soon everyone you see on film or TV is going to be ‘shopped to look sexier, fitter, and skinnier than is actually natural.
