Scientists Intrigued by Conical Skull Found in Ancient Burial Ground

Archaeologists in Iran have discovered an ancient cone-shaped skull that is believed to have belonged to a teen girl — and there are signs of tragedy in her bones.
As Live Science reports, the skull, which was found in a prehistoric burial ground known as Chega Sofla without its corresponding skeleton, shows signs not only of intentional modification, but also possibly fatal blunt force trauma.
Dated to roughly 6,200 years old, the strange cone shape of the skull appears to be the product of a practice archaeologists today call artificial cranial modification, a process similar to foot-binding in which the soft skulls of children are bandaged to deliberately deform them.
Found across cultures and millennia, this type of body modification has been undertaken for various reasons, including to denote social status or adhere to beauty standards, as evidenced by it more often being seen in girls than boys. Though it's still occasionally practiced today, the practice sometimes referred to as "skull elongation" was far more common in prehistoric times. The girl with the conical skull in this study, for instance, was believed to have lived in the fifth millennium BCE.
Aside from the cone-shaped cranium of the young woman, who was believed to be younger than the age of 20, archaeologists Mahdi Alirezazadeh and Hamed Vahdati Nasab of the Tarbiat Modares University in Tehran — who also authored a study about their discovery that was recently published in the International Journal of Osteoarcheology — also found a long, unhealed fracture on the back of the skull that likely killed her.
"We know this woman experienced the fracture in the final moments of her life," Alirezazadeh told Live Science, "but we don't have any direct evidence to say that someone intentionally struck her."
Though it's unclear whether the ancient teen in question was intentionally killed or died by accident, the researchers believe that the modified shape of her skull likely made it weaker and more susceptible to trauma than a conventional cranium.
Along with pointing out that an unmodified fractured skull was found alongside the conical skull in the portion of Chega Sofia where they were working, Alirezazadeh also noted that whatever killed the latter "was so severe that it would have fractured a normal, unmodified skull as well."

'Completely new and totally unexpected finding': Iron deficiency in pregnancy can cause 'male' mice to develop female organs

When you buy through links on our articles, Future and its syndication partners may earn a commission. Iron deficiency during pregnancy can cause a male mouse embryo to develop female features, a new study reveals. The low iron disrupts the activation of a key gene that spurs the development of male sex organs. This causes embryos with XY chromosomes — the most common combination seen in males — to develop female sex organs instead. "This is a completely new and totally unexpected finding," study co-author Peter Koopman, a professor emeritus of developmental biology at the University of Queensland in Australia, told Live Science. "It's never been shown before that iron can flip such an important developmental switch." Earlier research established that the SRY gene on the Y chromosome is the "master switch" for turning on the development of male organs in mammals. An enzyme called JMJD1A plays an important role in flipping this master switch, and it requires iron to function properly. However, the connection between iron levels and sex determination was not fully understood. Now, in a study published June 4 in the journal Nature, researchers report that iron is essential for the development of testes in XY mice. The results show that maternal iron deficiency disrupts the activity of JMJD1A, which lowers SRY expression and drives the development of ovaries in XY mouse embryos. However, it's too early to say whether this finding in mice might translate to human pregnancy and sex development, Tony Gamble, an associate professor of biological sciences at Marquette University in Milwaukee who wasn't involved in the study, told Live Science. Related: Is there really a difference between male and female brains? Emerging science is revealing the answer. In the study, the researchers used pharmaceutical treatments and low-iron diets to manipulate the iron levels in pregnant mice. When the pregnant mice experienced iron deficiency, this caused six out of 39 total XY embryos to develop ovaries instead of testes. Investigating further, they found that genetics appear to be a factor in which embryos are sensitive to this effect. To confirm this mechanism, the team also grew embryonic gonads — structures that develop into testes or ovaries in the womb — in lab dishes so they could directly observe the impact of iron depletion. These lab analyses showed that reducing the iron in cells to 40% of normal levels led to a large increase in histones on the SRY gene. Histones are proteins that bind DNA and help control which genes are switched on, and this effect almost completely blocked the SRY gene's expression. Normally, the JMJD1A enzyme rids the SRY gene of histones, allowing it to turn on. The researchers hypothesize that when iron levels drop, the enzyme's activity is compromised, so suppressive histones build up on the SRY gene. These results suggest that "some important developmental traits that were previously thought to be purely genetically controlled can also be seriously impacted by nutrition and metabolic factors," Koopman said. And "if iron can have such an impact on sex development, then maybe other organ systems may also critically depend on iron or other dietary factors in a similar way," he added. Because the research was conducted solely in mice, the question of whether iron may have similar effects in humans is still open. Although sex determination follows a broadly similar blueprint across mammals, there are some important differences between mice and humans, Gamble said. RELATED STORIES —Scientists made mice with Y chromosomes female by deleting just 6 tiny molecules —One in 500 men may carry an extra sex chromosome (most without knowing it) —These bacteria trigger a sex change in wasps — scientists finally know how For example, while both species rely on the same genes to drive the development of testes, the consequences of mutations in these genes differ between the two species. Their similarities to humans make mice important models for studying development and disease, Gamble said, "but the differences urge caution in simply assuming processes are acting identically across both species." Testing the new finding in humans won't be easy, since many of the experiments possible in mice can't ethically be done in humans, Koopman said. "So, the way forward will have to involve doing biochemical, cell culture and gene expression experiments to build a body of indirect evidence that what holds true in mice is also the case in humans," he said.

One U.S. State Is ‘Overdue' for a Major Earthquake, Study Finds

A new study published in the journal JGR Solid Earth has found that one U.S. state is 'overdue' for an earthquake. Lead author Vasiliki Mouslopoulou believes that the information, while chilling, presents an opportunity to correct the course. "The main message to take away is that everyone could benefit, including California," Mouslopoulou told Live Science. Mouslopoulou and her co-authors collected data from California as well as four other earthquake-prone regions: the Basin and Range province, which encompasses most of Nevada, Utah, Arizona, and northwestern Mexico; Japan; Greece; and New Zealand. Earthquake scientists use this data to determine which areas might be at risk for a future incident by measuring the period since the last serious earthquake to the average amount of time between two big earthquakes throughout history. An area is considered to be 'overdue' for an earthquake if the amount of time since the last quake exceeds by 50 years the average amount of time between two large study found that roughly 45 percent of the fault lines in California are overdue for a massive earthquake when compared to less than 20 percent in the other regions studied. Mouslopoulou posits that the other models might be influenced by California's erratic earthquake patterns, which could prove problematic for predicting earthquakes in the future. At this point, data suggests that California won't remain in this pattern forever. If the state segues into a more active phase of earthquakes, Mouslopoulou believes it's likely the state will eventually align with faults around the globe. Mouslopoulou will next compare California's fast faults, such as San Andreas which generates earthquakes in 'supercycles,' or clusters, with other fast-slip systems across the globe, like those in Turkey or off the coast of Chile. "It will be very interesting to see how these fast-moving faults and regions compared to the Californian faults," Mouslopoulou said.
