A partial human skull found in northern Israel excited paleontologists because it seemed to hold clues about when and where humans and Neanderthals might have interbred.
The Manot Cave is a natural limestone formation that had been sealed for 15,000 years. It was discovered by a bulldozer clearing the land for development and the partial skull, sitting on a ledge, was found by spelunkers exploring the newly-opened cave. Five excavation seasons uncovered a rich deposit, with stone tools and stratified occupation levels covering a period of time from 55,000 to 27,000 years ago.
A new paper believes that a record drought in Syria from 2006-2010 and the 2011 Syrian uprising is not a coincidence. The rebellion was stoked by ongoing man-made climate change, they write.
The drought, the worst in modern record-keeping, destroyed agriculture in the breadbasket region of northern Syria, driving dispossessed farmers to cities, where poverty, government mismanagement and other factors created unrest that exploded in spring 2011. The conflict has since evolved into a complex multinational war that may have killed 200,000 people and displaced many more.
Deep in the heart of synthetic biology are the proteins that make it tick and that is why protein engineering is crucial to the new discipline: Scientists grow, harvest, and reprogram proteins to become new drug therapeutics, environmentally friendly fuels, and vaccines.
But producing proteins quickly and in large quantities has been and remains a major challenge in the field, so Northwestern University synthetic biologist Michael Jewett and colleagues have pioneered a new protein production method that is faster and cheaper than ever before, making synthetic biology research more accessible for laboratories everywhere--even in high schools.
In America, teachers with tenure can't be fired and so it is more important than ever that the best people get the jobs in the first place.
Accountability is not going away in the American educational system, and neither are education unions, so new mechanisms for selecting individuals into teacher preparation could boost the quality. A new
Video Assessment of Interactions and Learning (VAIL)
tool can inform teacher selection and help stop the ongoing educational reform undertaken by each new administration.
After they die, people are happy to donate their hearts, their eyes, even whole skeletons, without knowing anything at all about what will happen to them.
What about genetic information?
Under current law, your genetic information is not inherited by default, so a child with a heritable form of cancer can't access their parent's genetic information after death if no consent was ever established. Clearly there needs to be a policy in the post-Human Genome Project age.
A 10-year-old boy suffered seizures after over-indulging in licorice sweets and that has led to calls for manufacturers to put a warning on the labels of licorice.
After suffering a 2 minute tonic-clonic seizure, a 10-year-old boy was admitted to hospital in Bologna, Italy. Three more generalized seizures occurred over the next few hours and so Dr. Davide Tassinari and colleagues used cranial computed tomography (CT) and magnetic resonance imaging (MRI), to investigate the possibility of posterior reversible encephalopathy syndrome (PRES), but the major clinical conditions that lead to PRES were all ruled out.
