The timing, process and archeology of the peopling of Europe by early modern humans have been actively debated for more than a century. Reassessment of the anatomy and dating of a fragmentary upper jaw with three teeth from Kent's Cavern in southern England has shed new light on these issues. Originally found in 1927, Kent's Cavern and its human fossil have been reassessed by an international team, including Erik Trinkaus, PhD, professor of anthropology in Arts & Sciences at Washington University in St. Louis, and the results published in Nature. The Kent's Cavern human ...

Energy regulator, Ofgem, recently announced that the average duel gas and electricity bill is now GBP1,345 a year, and experts acknowledge that this figure can only go up. In addition, the trend of new-build properties coming with a gas fire as standard has been dealt a blow thanks to recent government regulations that demand increased efficiency. Rather than sit and wait while the price of domestic oil, gas and electricity keep rising, the benefits of renewable energy sources have been recognised by many Irish consumers, with retailers such as Dalzells of Markethill ...

STANFORD, Calif. -- When given for hours as a continuous dose, the heart medication nitroglycerin backfires -- increasing the severity of subsequent heart attacks, according to a study of the compound in rats by researchers at the Stanford University School of Medicine. "Basically it's a cautionary tale," said professor of chemical and systems biology Daria Mochly-Rosen, PhD, senior author of the study that will be published Nov. 2 in Science Translational Medicine. "Here is a practice in medicine used for over 100 years. Nitroglycerin is so old that a proper clinical ...

A recent increase in the intensity of tropical cyclones in the Arabian Sea may be a side effect of increasing air pollution over the Indian sub-continent, a new multi-institutional study has found. Traditionally, prevailing wind-shear patterns prevent cyclones in the Arabian Sea from becoming major storms. A paper appearing in the Nov. 3 issue of the journal Nature, however, suggests the weakening of the winds aloft has enabled the formation of stronger cyclones in recent years – including storms in 2007 and 2010 that were the first recorded storms ever to enter the Gulf ...

Pollution is making Arabian Sea cyclones more intense, according to a study in this week's issue of the journal Nature. Traditionally, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms. The Nature paper suggests that weakening winds have enabled the formation of stronger cyclones in recent years -- including storms in 2007 and 2010 that were the first recorded storms to enter the Gulf of Oman. Researchers note that weakening wind patterns during the last 30 years correspond with a buildup of aerosols in the atmosphere over ...

An international research team led by Dr. Cindy Leissinger of Tulane University School of Medicine, along with Dr. Alessandro Gringeri from the University of Milan, has found that a drug commonly used to treat bleeding events in people with a type of severe hemophilia can also be used to prevent such events from happening in the first place. The study, the first to confirm the efficacy and safety of the drug FEIBA™ in bleed prevention is published in the Nov. 3, 2011 issue of the New England Journal of Medicine. The study examined the ability of FEIBA to prevent bleeds ...

WINSTON-SALEM, N.C. -- The poor safety profile of the smoking-cessation drug varenicline (Chantix™) makes it unsuitable for first-line use, according to a study published in the Nov. 2 edition of the journal PLoS One, an online publication of the Public Library of Science. Varenicline, which already carries a "black box warning" from the U.S. Food and Drug Administration (FDA), showed a substantially increased risk of reported depression or suicidal behavior compared to other smoking-cessation treatments, according to researchers at Wake Forest Baptist Medical Center, ...

Stromal cells, as distinct from hematopoietic cells, are an essential component of the bone marrow microenvironment and are necessary for the long-term maintenance of hematopoietic stem cells (HSCs) in vitro. Previous studies have shown that stromal cells regulate the proliferation and differentiation of HSCs through the production of diffusible hematopoietic regulatory factors and extracellular matrix, and through physical cell-cell interactions involving adhesion molecules and gap junction-mediated cell communication. However, the ability of stromal cells to support the ...

Neurofibrillary tangles – odd, twisted clumps of protein found within nerve cells – are a pathological hallmark of Alzheimer's disease. The tangles, which were first identified in the early 1900s by German psychiatrist and neuropathologist Aloysius Alzheimer, are formed when changes in a protein called tau cause it to aggregate in an insoluble mass in the cytoplasm of cells. Normally, the tau protein is involved in the formation of microtubules, hollow filaments that provide cells with support and structure; abnormal tau tangles, however, cause that structure to break down, ...

Graphene, which is composed of a one-atom-thick layer of carbon atoms in a honeycomb-like lattice (like atomic-scale chicken wire), is the world's thinnest material – and one of the hardest and strongest. Indeed, the past few years have seen an explosion of research into the properties and potential applications of graphene, which has been touted as a superior alternative to silicon. Because graphene is a two-dimensional material, "all of it is an exposed surface," says physical chemist Phaedon Avouris, manager of the Nanometer Scale Science and Technology division at ...

Ann Arbor, Mich. -- A University of Michigan Health System laboratory study reveals a key trigger for producing normal red blood cells that could lead to a new treatment for those with sickle cell disease. The study, conducted in mice, appears in this week's early edition of the Proceedings of the National Academy of Sciences, and holds promise for preventing the painful episodes and organ damage that are common complications of sickle cell disease. According to the U-M study, increasing the expression of the proteins, TR2 and TR4, more than doubled the level of fetal ...

Much of the body's chemistry is controlled by the brain – from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the body. In the process, they discovered a surprising new role for the 'hormone of love,' showing that it helps to direct the development of this brain structure. The area in question, ...

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood. The findings may form the basis for a therapy for this disorder. In Batten disease, an insoluble yellow pigment accumulates in the brain's neurons, causing these cells to degenerate and ultimately die. Patients gradually become disabled, ...

Europe's leading scientists have pledged to embrace and expand the role of technology in the Humanities. In a Science Policy Briefing released today by the European Science Foundation (ESF), they argue that without Research Infrastructures (RIs) such as archives, libraries, academies, museums and galleries, significant strands of Humanities research would not be possible. By drawing on a number of case studies, the report demonstrates that digital RIs offer Humanities scholars new and productive ways to explore old questions and develop new ones. According to Professor ...

Eating a Mediterranean diet combined with physical activity can help to improve some of the symptoms of sleep apnoea, according to new research. The study, which is published online in the European Respiratory Journal, looked at the impact a Mediterranean diet can have on obese people with sleep apnoea, compared to those on a prudent diet. Obstructive sleep apnoea syndrome (OSAS) causes frequent pauses of breathing to occur during sleep, which disrupts a person's normal sleeping pattern. It is one of the most prevalent sleep-related breathing disorders with approximately ...

According to a new study by researchers from the MPI for Psycholinguistics and the MPI for Evolutionary Anthropology, you don't need to have words for emotions to understand them. The results of the study were published online on October 17 in Emotion, a journal of the American Psychological Association. The study provides new evidence that the perception of emotional signals is not driven by language, supporting the view that emotions constitute a set of biologically evolved mechanisms. The study compared German speakers to speakers of Yucatec Maya, a Mayan language ...

According to company president Ron Kresha: "The key to our ...

Investigators estimate that there are currently more than 15 million photographs of child abuse victims circulating on the Internet. By the time this material has been tracked down and deleted, pedophiles have long since downloaded it to their computers. Many are avid data collectors: when suspects' data media are confiscated, detectives must often click their way through hundreds of thousands of files to find the illegal images they seek. An extremely time-consuming process – until now. Because researchers working with Dr. Bertram Nickolay of the Fraunhofer Institute for ...

As soon as DNA is mentioned, we automatically think of biology and living beings. It is the DNA molecule found inside each and every cell that holds the encoded blueprints for humans, animals or plants. But factories too have a master plan of this kind. All modern manufacturing facilities resemble living organisms in their complex structure. And, just as in biology, all their constituent parts are linked to one another and have to be painstakingly coordinated. Now, the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation IOSB in Karlsruhe has taken ...

With flu season just around the corner, scientists are reporting development of a new material for the fiber in face masks, air conditioning filters and air cleaning filters that captures influenza viruses before they can get into people's eyes, noses and mouths and cause infection. The report on the fiber appears in ACS' journal Biomacromolecules. Xuebing Li, Peixing Wu and colleagues explain that in an average year, influenza kills almost 300,000 people and sickens millions more worldwide. The constant emergence of new strains of virus that shrug off vaccines and anti-influenza ...

For the first time, scientists report a link between eating nuts and higher levels of serotonin in the bodies of patients with metabolic syndrome (MetS), who are at high risk for heart disease. Serotonin is a substance that helps transmit nerve signals and decreases feelings of hunger, makes people feel happier and improves heart health. It took only one ounce of mixed nuts (raw unpeeled walnuts, almonds and hazelnuts) a day to produce the good effects. The report appears in ACS' Journal of Proteome Research. Cristina Andrés-Lacueva and colleagues from the Biomarkers ...

Concerns that global warming may have a domino effect —unleashing 600 billion tons of carbon in vast expanses of peat in the Northern hemisphere and accelerating warming to disastrous proportions — may be less justified than previously thought. That's the conclusion of a new study on the topic in ACS' journal Environmental Science & Technology. Christian Blodau and colleagues explain that peat bogs — wet deposits of partially decayed plants that are the source of gardeners' peat moss and fuel — hold about one-third of the world's carbon. Scientists have been concerned ...
