"This year’s IPHES archaeological campaign at the Cova de les Borres,in the municipality of La Febró (Baix Camp) has ended. Its main objective was to characterise the different archaeological levels that had been excavated in previous years. This year excavators found ~1,500 remains, ~1,300 lithics and 200 faunal remains, all of which will help researchers to better understand how hominids lived near the Siurana River between ~9-13 Ky.
Regarding the lithic industry, excavators unearthed cores, flakes and retouched tools such as, scrapers, blades and backed bladelets. These tools are made mainly of flint, but also quartz, quartzite and sandstone, which confirms the use of different raw materials from the environment of the Prades Mountains.
In terms of faunal remains, those recovered from higher levels were more exposed to environmental factors and acidic conditions that hinder preservation. This year, in the oldest levels, remains were better preserved. ”We still do not know to which species they belong but we will soon analyse them in the laboratory at IPHES. However, if they follow the trend of previous years, goat and rabbit will predominate,” said Maria Soto, IPHES archaeologist and co-director of the excavation along with Joseph Vallverdú” (read more in Catalan).

“In 2012, I got my Ph.D. and left academia with no regrets. Like all decisions based on financial stability, it was not so much a decision as a reaction. Academia, I had discovered, was not an industry in which one works for pay but one in which you must pay to work. New Ph.D.’s are expected to move around the country in temporary postdocs or visiting professor jobs until finding tenure-track positions — financially impossible for me as a mother of two – or stay where they are and work as adjuncts with no job security and an average wage of $2,700 per course. While making an income below the poverty line, a new Ph.D. is expected to spend thousands of dollars on job interviews at conferences in expensive cities and write paywalled papers for free.
I left. But there is no escaping the consequences of academia’s reliance on contingent labor. If you do not experience the adjunct crisis directly as an academic, you may well experience it as a citizen: as a student, a parent, or a professional facing a similar contingency crisis in your own field. The adjunct crisis in academe both reflects and advances a broader crisis in labor. Our exploited professors are teaching our future exploited workers.
On February 25, 2015, adjunct professors across the United States are planning to walk out of the classroom to protest their low pay, lack of benefits, and unfair treatment. Their struggle is one we all should support. Here are the reasons why you should care.
Labor exploitation is not the new normal. Adjunct professors are distinct from other low-wage contract workers only by virtue of degree – that is, the Ph.D. Like other exploited workers, adjuncts are told that their low pay and mistreatment are the deserved consequence of poor choices. While low-wage workers without college degrees are told to get an education, adjuncts are asked what they thought all that education would get them. The plight of the adjunct shows one can have all the education in the world and still have no place in it” (read more).

"West Asia is a key locale for the investigation of Paleolithic human migration and adaptation because of the area’s location at the crossroads between Africa and Eurasia as well as its diverse environmental settings. Geographic units in west Asia comprise the Levant, the Zagros and Taurus Mountains, Anatolia, the Caucasus, and the Arabian Peninsula. In the Levant, east Mediterranean coastal plains and the rift valley extending between the Red Sea and the Afrin Basin provided significant habitats and migration routes for early humans during the Paleolithic. To its east, inland areas of the Syrian Desert and the Jordanian Badia are presently under arid environments, but the inland basins, often associated with oases, such as el-Kowm, Palmyra, Azraq, and Jafr, used to hold Pleistocene lakes, around which prehistoric sites are clustered. The rugged terrains and cave systems in the Zagros–Taurus and the Caucasus Mountains have also been important fields for the study of early human habitations. In the Arabian Peninsula, a number of Paleolithic sites have been located in various environmental settings, including coastal plains, foothills of the Asir and Hadhramaut Mountains, as well as near wadis and lake shores in interior plains" (read more/open access).

Q:Any tips (or studies) on Geometric Morphometrics?

“Arie van ’t Riet has a unique view of life on earth. As a medical physicist based in the Netherlands, van ’t Riet teaches radiographers about radiation physics and safety. As part of his teaching program, van ’t Riet searched for an example to demonstrate and visualise the influence of x-ray energy on the contrast of an x-ray image. The higher the x-ray energy, the lower the contrast. “I arrived at flowers. After some years I started to edit and partly colour these x-ray images. And I added animals,” he says. van ’t Riet now produces a series of x-ray artworks demonstrating the inner beauty of life.
Each image is produced at his home, where he has an x-ray machine under licence. All the animals imaged were already dead. “It’s not justified to expose living animals to the risk of x-rays,” he says. His work has now given him a new perspective on nature” (read more).
Wonderful plastination, showing the nerves and muscles of the head/neck region. Note the thyroid being in front of the trachea, and the small muscles heading towards the eye enabling us to look around without moving our head.

“Ancestry assessments using cranial morphoscopic traits currently rely on subjective trait lists and observer experience rather than empirical support. The trait list approach, which is untested, unverified, and in many respects unrefined, is relied upon because of tradition and subjective experience. Our objective was to examine the utility of frequently cited morphoscopic traits and to explore eleven appropriate and novel methods for classifying an unknown cranium into one of several reference groups. Based on these results, artificial neural networks (aNNs), OSSA, support vector machines, and random forest models showed mean classification accuracies of at least 85%. The aNNs had the highest overall classification rate (87.8%), and random forests show the smallest difference between the highest (90.4%) and lowest (76.5%) classification accuracies. The results of this research demonstrate that morphoscopic traits can be successfully used to assess ancestry without relying only on the experience of the observer” (read more/open access).

Walking With Lucy | California Academy of Sciences
Appearing next to a full—scale recreation of the famous “Lucy” skeleton (Australopithecus afarensis) in Tusher African Hall, this computer animation compares the distinctive gaits of a chimpanzee, A. afarensis, and modern human, highlighting the trait of upright walking that the latter two share.
