It is the first time that extensive tests have been carried out on an intact prehistoric mummy, consolidating the researchers' previous findings that embalming was taking place 1,500 years earlier than previously accepted.
Dating from c.3700-3500 BC, the mummy has been housed in the Egyptian Museum in Turin since 1901, but unlike the majority of other prehistoric mummies in museums, it has never undergone any conservation treatments, providing a unique opportunity for accurate scientific analysis.
Lausanne, Switzerland - In a series of studies, social psychologists show that educational tracking - grouping students based on their achievement levels - encourages evaluators to artificially create social class inequalities. Three studies reveal that evaluators consider a lower track more suitable for a low socioeconomic status (SES) pupil and a higher track more suitable for a high-SES pupil, even when school achievement was identical.
Socio-economic position determines the environmental hazards--such as air pollution and noise--that pregnant women are exposed to in urban areas, although the nature of the association varies from city to city. This was the main conclusion of a new study conducted with the participation of the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Banking Foundation.
As sea levels rise due to climate change, so do the global hazards and potential devastating damages from tsunamis, according to a new study by a partnership that included Virginia Tech.
Even minor sea-level rise, by as much as a foot, poses greater risks of tsunamis for coastal communities worldwide.
UNIVERSITY PARK, Pa. -- The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight into how this process seals off waste, much like a trash bag.
Scientists in Norfolk, VA (USA) have developed a new method of making collagen microfibres, which could have applications in research, medical devices and clinical treatments ranging from ligament damage to skin burns.
While collagen fibre manufacturing methods such as electrospinning and extrusion exist for biomedical applications, they have seen limited clinical success. This is partially due to challenges of scalability, cost, and complexity.
New research, published in the European Heart Journal [1] today (Wednesday), has shown deaths from conditions that affect the blood supply to the brain, such as stroke, are declining overall in Europe but that in some countries the decline is levelling off or death rates are even increasing.
BUFFALO, N.Y. -- A class of proteins that has generated significant interest for its potential to treat diseases, has for the first time, been shown to be effective in reducing relapse, or drug-seeking behaviors, in a preclinical study.
Published online in July in Biological Psychiatry, the University at Buffalo research reveals important new information about the molecular changes that occur in the brain when an individual takes cocaine, and how these molecules can be targeted to reduce drug-seeking behaviors during withdrawal.
Blood platelets are like the sand bags of the body. Got a cut? Platelets pile in to clog the hole and stop the bleeding.
But genetic mutations, infections and even radiation from cancer treatments can slash platelet numbers, leading to a condition called thrombocytopenia and putting people at risk for internal bleeding.
Research published today reveals a potential mechanism for migraine causation which could explain why women get more migraines than men. The study, in Frontiers in Molecular Biosciences, suggests that sex hormones affect cells around the trigeminal nerve and connected blood vessels in the head, with estrogens -- at their highest levels in women of reproductive age -- being particularly important for sensitizing these cells to migraine triggers.
PROVIDENCE, R.I. [Brown University] -- Polyploidal cancer cells--cells that have more than two copies of each chromosome--are much larger than most other cancer cells, are resistant to chemotherapy and radiation treatments and are associated with disease relapse. A new study by Brown University researchers is the first to reveal key physical properties of these "giant" cancer cells.
SAN FRANCISCO -- When people are rude to their coworkers or treat them badly, they probably don't realize the unintended victims in that encounter could be the coworkers' children. Women who experience incivility in the workplace are more likely to engage in stricter, more authoritarian parenting practices that can have a negative impact on their children, according to research presented at the annual convention of the American Psychological Association.
LAWRENCE -- Younger generations of religious Americans tend to closely harbor concerns for the environment via stewardship more so than older parishioners, according to a study by a University of Kansas researcher.
A new LSU Pennington Biomedical Research Center study reveals that a novel biomarker might give us new answers necessary to creating a diagnostic tool for hypoglycemia-associated autonomic failure (HAAF). No objective diagnostic tool currently exists for this condition which, if left untreated, can lead to ever-worsening and possibly life-threatening episodes of dangerously low blood sugar.

Despite promising advances, important scientific questions remain unanswered in the effort to develop a safe and effective Ebola vaccine, according to members of an international Ebola research consortium. In a Viewpoint published in The Lancet, the experts review the current field of Ebola vaccine candidates and clinical trials and highlight key gaps in knowledge that need to be addressed by future research.
