Skull of oldest horned dinosaur in North America found

Guardian Science - Wed, 2014-12-10 21:33

Fossil from tiny plant eater, Aquilops americanus, suggests horned dinosaurs originated in Asia

The oldest horned dinosaur in North America sported a hooked beak, pointy cheeks, and was no bigger than a crow, according to research on its ancient remains.

The skull of the prehistoric creature that stalked the land more than 100m years ago was recovered by fossil hunters from rock in Carbon County, Montana. The skull, discovered by Scott Madsen of the Utah Geological Survey, which investigates and reports on Utah’s geologic hazards, measured only 8.4cm long and dates to about 106m years old.

Phthalates risk damaging children’s IQs in the womb, US researchers suggest

Guardian Science - Wed, 2014-12-10 20:40
Additives found in plastics and scented products could affect brain development and lower IQ

Pregnant women should avoid additives called phthalates found in common household products, according to US researchers, who found evidence that the substances may reduce children’s IQ.

Children whose mothers had the highest levels of phthalates had IQs on average seven points below those whose mothers had the lowest. The 328 women from inner-city New York who took part in the study had levels of phthalates in urine measured in the last weeks of pregnancy. IQs of the children were tested at seven years old.

Blood grown from stem cells could transform transfusions

Stem-cell technology is being used to grow fresh human blood in the laboratory – but don’t hand in your donor card just yet

■ See more from the 20 innovations for 2015 series

In 2007, a team of researchers from the UK and Irish Blood services responded to an oddly specific call from the US military. They wanted scientists to help them build a machine, no bigger than two and a half washing machines, that could be dropped from a helicopter on to a battle field and generate stem-cell-derived blood for injured soldiers.

The team’s application was not successful, but they refocused their efforts and set off on a more utopian mission – to develop a similar technology to create a limitless supply of clean, laboratory-grown blood for use in clinics around the world. Using blood made from stem cells would unshackle blood services from the limits of human supply, and any risk of infection would be removed.
