A researcher in Sweden has shown that this conflict is leading to a difference in reproductive success between men and women of varying height.Tue, 13 Nov 2012 08:35:35 ESThttp://www.sciencedaily.com/releases/2012/11/121113083536.htmCatch and release of rare cancer cells inspired by jellyfishhttp://www.sciencedaily.com/releases/2012/11/121112171314.htm A research team has developed a novel device that may one day have broad therapeutic and diagnostic uses in the detection and capture of rare cell types, such as cancer cells, fetal cells, viruses and bacteria.Mon, 12 Nov 2012 17:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121112171314.htmJellyfish-inspired device that captures cancer cells from blood samples could enable better patient monitoringhttp://www.sciencedaily.com/releases/2012/11/121112171312.htm Tumor cells circulating in a patient's bloodstream can yield a great deal of information on how a tumor is responding to treatment and what drugs might be more effective against it. But first, these rare cells have to be captured and isolated from the many other cells found in a blood sample. Scientists are now working on microfluidic devices that can isolate circulating tumor cells.Mon, 12 Nov 2012 17:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121112171312.htmNew cause of thyroid hormone deficiency discoveredhttp://www.sciencedaily.com/releases/2012/11/121112135615.htm Researchers have discovered a new cause for thyroid hormone deficiency, or hypothyroidism. The scientists identified a new hereditary form of hypothyroidism that is more prevalent in males than in females. This sex bias shone a light on where to look for the underlying cause.Mon, 12 Nov 2012 13:56:56 ESThttp://www.sciencedaily.com/releases/2012/11/121112135615.htmGenetic link between pancreatitis and alcohol consumptionhttp://www.sciencedaily.com/releases/2012/11/121112135520.htm A new study reveals a genetic link between chronic pancreatitis and alcohol consumption. Researchers found a genetic variant on chromosome X near the claudin-2 gene (CLDN2) that predicts which men who are heavy drinkers are at high risk of developing chronic pancreatitis.Mon, 12 Nov 2012 13:55:55 ESThttp://www.sciencedaily.com/releases/2012/11/121112135520.htmHumans are slowly but surely losing intellectual and emotional abilities, article suggestshttp://www.sciencedaily.com/releases/2012/11/121112135516.htm Human intelligence and behavior require optimal functioning of a large number of genes, which requires enormous evolutionary pressures to maintain. A provocative theory suggests that we are losing our intellectual and emotional capabilities because the intricate web of genes endowing us with our brain power is particularly susceptible to mutations and that these mutations are not being selected against in our modern society.Mon, 12 Nov 2012 13:55:55 ESThttp://www.sciencedaily.com/releases/2012/11/121112135516.htmHow chronic inflammation can cause cancerhttp://www.sciencedaily.com/releases/2012/11/121112135512.htm A new study has found that interleukin-15 (IL-15) alone can cause large granular lymphocytic (LGL) leukemia, a rare and usually fatal form of cancer. The researchers developed a treatment for the leukemia that showed no discernible side effects in an animal model. The study shows that IL-15 is also overexpressed in patients with LGL leukemia and that it causes similar cellular changes, suggesting that the treatment should also benefit people with the malignancy.Mon, 12 Nov 2012 13:55:55 ESThttp://www.sciencedaily.com/releases/2012/11/121112135512.htmList of diseases spread by deer tick grows, including malaria-like problems and potentially fatal encephalitishttp://www.sciencedaily.com/releases/2012/11/121112135510.htm An emerging tick-borne disease that causes symptoms similar to malaria is expanding its range in areas of the northeast where it has become well-established, according to new research.Mon, 12 Nov 2012 13:55:55 ESThttp://www.sciencedaily.com/releases/2012/11/121112135510.htmParkinson's disease: Compensation in the brain could lead to new treatmenthttp://www.sciencedaily.com/releases/2012/11/121112135404.htm New evidence indicates that Parkinson's disease is preceded by a period during which healthy regions of the brain take over the functions of damaged ones.Mon, 12 Nov 2012 13:54:54 ESThttp://www.sciencedaily.com/releases/2012/11/121112135404.htmGene sequencing project identifies abnormal gene that launches rare childhood leukemiahttp://www.sciencedaily.com/releases/2012/11/121112135229.htm Research has identified a fusion gene responsible for almost 30 percent of a rare subtype of childhood leukemia with an extremely poor prognosis. The finding offers the first evidence of a mistake that gives rise to a significant percentage of acute megakaryoblastic leukemia (AMKL) cases in children. AMKL accounts for about 10 percent of pediatric acute myeloid leukemia (AML). The discovery paves the way for desperately needed treatment advances.Mon, 12 Nov 2012 13:52:52 ESThttp://www.sciencedaily.com/releases/2012/11/121112135229.htmGenome sequencing of Burkitt Lymphoma reveals unique mutationhttp://www.sciencedaily.com/releases/2012/11/121112113133.htm In the first broad genetic landscape mapped of a Burkitt lymphoma tumor, scientists identified 70 mutations, including several that had not previously been associated with cancer and a new one that was unique to the disease.Mon, 12 Nov 2012 11:31:31 ESThttp://www.sciencedaily.com/releases/2012/11/121112113133.htm
