At least a third of all people living in the ancient American city of Cahokia were immigrants, a new study has found.
If global surface temperatures rise to 2 degrees Celsius above pre-industrial levels, the majority of Europe will experience higher levels of global warming than other places around the globe, according to a new study.
Breast cancer patients with high levels of vitamin D in their blood are twice more likely to survive the disease than women with low levels of this nutrient, research suggests. Researchers suggest physicians consider adding vitamin D into a breast cancer patient's standard care now and then closely monitor the patient.
An asteroid or a comet hit Mars nearly 5 million years ago. The impact was so great that several rocks were hurled into space. Few of these rocks travelled millions of miles to land on Earth. A new study shows that 34-mile-wide Mojave crater on the Red Planet is the source of these Martian meteorites.
Thirty percent of adults with Attention Deficit Disorder or Attention Deficit Hyperactivity Disorder (ADD/ADHD) report that they were physically abused before they turned 18. This compares to seven percent of those without ADD/ADHD who were physically abused before the age of 18. With 30 percent of adults with ADD/ADHD reporting childhood abuse, it is important that health professionals working with children with these disorders screen them for physical abuse.
Scientists have identified a gene, which helps to regulate how different genes operate in different cell types. This finding may now allow scientists to find new ways to target and treat aggressive types of breast cancer. Scientists have pinpointed a gene, TAZ, which controls whether breast cells behave more like basal cells or more like luminal cells, information that might be important in understanding and possibly treating difficult-to-treat forms of breast cancer. Researchers have known for a long time that breast cells can lose their normal identity when they become cancerous, but are now realizing that normal cells can change their characteristics as well in response to transcription factors like TAZ. This might be a factor in the development of breast cancer. By identifying the genes responsible for this change in cells from breast tissue, researchers now hope to identify a way to stop or reverse it.
A study in the American Journal of Gastroenterology followed nearly 500,000 older U.S. adults and found that the risks of cancer were relatively greater among those who ate a large amount of red meat. However, a recent review underlines the uncertainties in the scientific evidence and suggests that further research is needed to resolve these issues and improve the foundation for future recommendations on the intake of red meat.
Researchers have found a critical link between extra body fat and diabetes. Higher levels of a molecule called Retinol Binding Protein 4 (RBP4) play a key role in the development of insulin resistance. RBP4 creates a complex interplay between two branches of the body's immune system, leading to chronic fat tissue inflammation and, ultimately, insulin resistance. High RBP4 leads to insulin resistance, as well as cardiovascular risk factors such as hypertension and elevated levels of LDL cholesterol.
Researchers at University of California, Los Angeles have used a new class of materials called "multiferroic magnetic materials" to reduce the energy consumed by logic devices. Multiferroics can increase power efficiency for processing by up nearly 1,000 times.
The unparalleled longevity of a hormone-producing tissue in the Eurasian lynx could possibly be utilized to assist in the conservation of the endangered Iberian lynx, one of the most threatened wild cats on Earth.
Researchers from the London School of Hygiene & Tropical Medicine and the University of Michigan are reporting the first hard evidence that malaria creeps to higher elevations during warmer years and falls back down to lower altitudes when temperatures cool.
Researchers have developed a method for the large-scale manufacture of everyday objects like toys and cellphone cases using a plastic derived from shrimp shells.
Prenatal exposure to nicotine could manifest as Attention Deficit Hyperactivity Disorder in children born a generation later, according to a new study by Florida State University College of Medicine researchers.
Researchers have now found fossil remains of the largest carnivore dinosaur to roam Europe. The dinosaur- Torvosaurus gurneyi- was from late Jurassic and was 33 feet long with razor-sharp teeth.
