Scientists have cracked the genetic code and predicted some high priority drug targets for the blood parasite Schistosoma haematobium, which is linked to bladder cancer and HIV/ AIDS and causes the insidious urogenital disease schistosomiasis haematobia in more than 112 million people in Africa. Schistomiasis is recognized by the World Health Organization as one of the most socioeconomically devastating diseases, besides malaria, and is in urgent need of extensive research and improved...

For a bigger harvest and faster results: The University of Hohenheim, the MPI for Molecular Plant Physiology and the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben start a new chapter in plant breeding In order to breed new varieties of corn with a higher yield faster than ever before, researchers at the University of Hohenheim in Stuttgart, Germany, and other institutions are relying on a trick: early selection of the most promising parent plants based on their...

New method for observing enhancer activity during development As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell´s nucleus, genetic sequences known as enhancers act like remote controls, switching genes on and off. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, can now see — and predict — exactly when each remote control is itself activated, in a...

The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein, said Baylor College of Medicine scientists in a report that appears online in the journal Nature Genetics. Much of the work was done at the Jan and Dan L. Duncan Neurological Research Institute at Texas...

A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids (HDLS). This is a devastating disorder of the brain´s white matter that leads to death between ages 40...

Scientists have uncovered a critical genetic mutation in some patients with myelodysplastic syndromes – a group of blood cancers that can progress to a fatal form of leukemia. The research team at Washington University School of Medicine in St. Louis also found evidence that patients with the mutation are more likely to develop acute leukemia. While this finding needs to be confirmed in additional patients, the study raises the prospect that a genetic test could one day more...

In the bone marrow, blood-forming (hematopoietic) stem cells become one of the myriad kinds of blood cells in the body or they can self-renew, maintaining that pool. However, the lack or mutation of a gene for an enzyme called Dnmt3a (DNA methyltransferase 3a) results in an abundance of stem cells and a lack of blood cells, said a consortium of researchers led by those at in the Stem Cells and Regenerative Medicine Center at Baylor College of Medicine in a report online in the journal...

A rare genetic disorder has given researchers at the Peninsula College of Medicine and Dentistry, University of Exeter, a surprising insight into how the pancreas develops. The finding provides a clue to how it may be possible to 'program' stem cells — master cells in the body that can develop into specialized cells — to become pancreatic cells. Pancreatic agenesis is a rare condition in which the body is unable to produce a pancreas. The pancreas plays an essential role in...

Pancreatic agenesis is a rare condition in which the body is unable to produce a pancreas. The pancreas plays an essential role in regulating levels of sugar (glucose) in the...

Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
