Lead was used in a wide range of consumer and commercial products over the last century. Unfortunately, lead is also a highly toxic metal that is known to cause serious health problems and even death. The most common source of lead poisoning today is lead-based paint. While lead paint has been removed from buildings in the past few decades, lead paint chips and lead dust are still a common sight in many apartment buildings. These problems are especially bad in low-rent buildings, most of which have not been rehabbed. Children have the greatest risk of developing lead ...

Atlanta tree services company Yellow Ribbon Tree Experts is reminding homeowners and property managers of the importance of properly preparing trees for winter. Although Atlanta winters are generally mild compared to many other regions of the country, freezing temperatures are not uncommon, especially at night, and winter can mean death for a tree that has not been sufficiently prepared. Winter air is known to dry out the skin, and it can have a similar effect on trees as well. To ensure that trees have enough water, it is important to water them thoroughly through the ...

From individual to collective failings are all due to our brains running on false emotional data generated by the selfish self-image. From wars to divorce, from Wall Street greed to the absence of pure happiness, from depression to corruption, from economic deficits to anger and all the other ills of society, the basic cause is our defective emotional intelligence. Scientists are reluctant to take up emotional intelligence education as emotional intelligence is connected to the mind, brain and consciousness; topics that science has not been able to define and understand ...

Accelerated partial breast irradiation using brachytherapy (APBIb) for the treatment of breast cancer has been rapidly increasing over the last several years in the U.S. as an alternative to standard whole-breast irradiation (WBI), according to a study published December 16th in the Journal of the National Cancer Institute. Various types of APBI recurrence (external beam radiation, intraoperative radiotherapy, brachytherapy using multiple interstitial catheters, or intracavitary brachytherapy using a balloon catheter) deliver radiation to breast tissue at the highest ...

Among people recently infected with HIV, immediate antiretroviral therapy (ART) appears preferable to deferring treatment, according to a new study published in the Journal of Infectious Diseases and now available online. Although the benefits of ART during early HIV-1 infection remain unproven, the findings support growing evidence favoring earlier ART initiation. Christine Hogan, MD, of the Medical College of Wisconsin in Milwaukee, led a team of researchers from various institutions to investigate the effects of ART on individuals infected with HIV-1 within the previous ...

A team of researchers from the University of Notre Dame have demonstrated a novel DNA detection method that could prove suitable for many real-world applications. Physicists Carol Tanner and Steven Ruggiero led the team in the application of a new technique called laser transmission spectroscopy (LTS). LTS is capable of rapidly determining the size, shape and number of nanoparticles in suspension. In a new paper appearing in the international, peer-reviewed, open-access, online publication PLoS ONE, the team describes how they applied LTS as a novel method for detecting ...

Are wage differences between men and women decreasing as more women attain managerial positions? A new Swedish report from the Uppsala Center for Labor Studies (UCLS) at Uppsala University and the Institute for Labour Market Policy Evaluation (IFAU) concludes that they are not. Manager gender is tied to neither wages nor, accordingly, wage differences on the labour market. Women held approximately 36 per cent of managerial positions within the Swedish employment market in 2008. That female managers are a minority is sometimes advanced as an explanation for the fact that ...

This press release is available in German.Chicago/Leipzig. Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change. As a result both the area burnt down annually and the average size of the fires would increase, write the researchers of the Helmholtz Centre for Environmental Research (UFZ) and the University ...

Although the temperate climates of central Europe provide plentiful food in summer, finding enough to eat is much more problematic in winter. Many small mammals avoid the problem by hibernating but this survival strategy is generally not practised by larger animals. With the exception of some bears, large mammals remain fully awake throughout the year, yet they too must reduce their metabolism to cope with the comparative scarcity of food. Red deer, for example, are known to lower their heart rate and to allow their extremities to cool substantially during winter. These ...

MicroRNAs or miRNAs are tiny RNA molecules that have only about 20 nucleotides and do not code for proteins. They regulate many important processes in cells by binding to target messenger RNAs – the instructions for protein production –, thus blocking production of the respective protein. In cancer, the production of some miRNAs is often reduced or amplified. This particularly affects miRNAs that regulate the activity of cancer-promoting genes. A key molecule in the development of cancer is a transcription factor called NFkappaB, which is an important switch for many ...

One in 13 teenage girls, aged 14 to 20, reported having a group-sex experience, with those young women more likely to have been exposed to pornography and childhood sexual abuse than their peers, according to a new study led by a Boston University School of Public Health (BUSPH) researcher. In a study published in the Journal of Urban Health: Bulletin of the New York Academy of Medicine, Emily Rothman, associate professor of community health sciences at BUSPH, and colleagues surveyed 328 females who had utilized a Boston-area community or school-based health clinic, to ...

Cold Spring Harbor, N.Y. – Cancer researchers at Cold Spring Harbor Laboratory (CSHL) have carried out the first comprehensive study of the changes seen in the DNA of a patient with mast cell leukemia (MCL), an extremely aggressive subtype of acute myeloid leukemia (AML) with a very poor prognosis. Their genomic survey has helped identify two previously unknown mutations that could directly influence patient response to currently available therapeutic drugs. The details uncovered by the study not only suggest a diagnostic improvement and an alternative treatment strategy ...

The research is based on studies of sediment from 36 lakes in the USA, Canada, Greenland and Svalbard, Norway. The researchers have analysed how the chemical composition of the sediment has changed over the centuries. Twenty-five of the lakes all show the same sign – that biologically active nitrogen from human sources can be traced back to the end of the 19th century. The nitrogen analyses of the lake sediments show that the changes began around 1895. The results also show that the rate of change has accelerated over the past 60 years, which is in agreement with the ...

Researchers from Harvard University and the Broad Institute have developed a tool that can tackle large data sets in a way that no other software program can. Part of a suite of statistical tools called MINE, it can tease out multiple patterns hidden in health information from around the globe, statistics amassed from a season of major league baseball, data on the changing bacterial landscape of the gut, and much more. The researchers report their findings in a paper appearing in the December 16 issue of the journal Science. From Facebook to physics to the global economy, ...

Adenoviruses can cause respiratory, eye, and intestinal tract infections, and, like other viruses, must hijack the cellular machinery of infected organisms in order to produce proteins and their own viral spawn. Now an international research team made up of scientists from Chinese and Australian universities has found a way to disrupt the hijacking process by using plasma to damage the viruses in the laboratory environment, before they come into contact with host cells. The researchers prepared solutions containing adenoviruses and then treated the samples with a low-temperature ...

Opening up a new door in synthetic biology, a team of researchers has developed a microfluidic device that produces a continuous supply of tiny lipid spheres that are similar in many ways to a cell's outer membrane. "Cells are essentially small, complex bioreactors enclosed by phospholipid membranes," said Abraham Lee from the University of California, Irvine. "Effectively producing vesicles with lipid membranes that mimic those of natural cells is a valuable tool for fundamental biology research, and it's also an important first step in the hoped-for production of an artificial ...

Microscopic-scale medical robots represent a promising new type of therapeutic technology. As envisioned, the microbots, which are less than one millimeter in size, might someday be able to travel throughout the human bloodstream to deliver drugs to specific targets or seek out and destroy tumors, blood clots, and infections that can't be easily accessed in other ways. One challenge in the deployment of microbots, however, is developing a system to accurately "drive" them and maneuver them through the complex and convoluted circulatory system, to a chosen destination. ...

Any multicellular animal, from a blue whale to a human being, poses a special challenge for evolution. Most of the cells in its body will die without reproducing; only a privileged few will pass their genes to the next generation. How could the extreme degree of cooperation required by multicellular existence actually evolve? Why aren't all creatures unicellular individualists determined to pass on their own genes? Joan Strassmann and David Queller, evolutionary biologists at Washington University in St. Louis, provide an answer in this week's issue of the journal ...

This press release is available in German. From shoals of fish to human society: social organisms need to make collective decisions. And it is not always the majority that prevails. In some cases, a small, resolute group may succeed in bending the whole community to their will. Using computer models and behavioural studies of fish, a team of scientists, including researchers from the Max Planck Institute for the Physics of Complex Systems in Dresden, has discovered that uninformed individuals support the decision of the majority and may prevent a particularly determined ...

MIAMI -- For anglers and boaters who regularly travel the coasts of Florida the great barracuda (Sphyraena barracuda) is a common sight. Surprisingly, however, very little is known about the early life stage of this ecologically and socio-economically important coastal fish. In the journal Marine Biology, lead author Dr. Evan D'Alessandro and University of Miami Rosenstiel School of Marine & Atmospheric Science colleagues Drs. Su Sponaugle, Joel Llopiz and Robert Cowen shed light on the larval stage of this ocean predator, as well as several other closely related species. ...
