U-M team identifies gene that regulates blood-forming fetal stem cells

...cation. A new University of Michigan study adds to mounting evidence that stem cells in the developing fetus are distinct from both embryonic and adult stem cells. In the last several years, stem cell researchers have realized that fetal stem cells comprise a separate class. They recognized, for example, th...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...ection, and this is followed by repeated cycles of mounting parasitic reproduction within red blood cells and accompanying fever. During red blood cell infection, P. falciparum degrades the hemoglobin in the red cell, producing a toxic byproduct known as heme, which the parasite then crystallizes so that it w...

Delayed treatment of childhood-onset bipolar disorder results in negative outcome in adults

...nformation contained in this report and additional mounting evidence suggest that early detection, diagnosis, and treatment are essential for determining effective treatment outcomes and, subsequently, quality of life for those affected with bipolar disorder. Earlier recognition and treatment of bipolar diso...

Immune response to cancer stem cells may dictate cancer's course

..., in cancer they're anything but helpful. In fact, mounting evidence is showing that a tumor's growth and spread may depend on "cancer stem cells," which comprise only a very small subset of the tumor. Now, a new study by Rockefeller University scientists shows that immunity to cancer stem cells may help prot...

New evidence of 'human' culture among primates

...s. While not conclusive, his research adds to a mounting body of evidence that suggests other species have something approaching human culture. A strong case has already been made for great apes having a capacity for social learning, but until now there has been no evidence of material culture among the "n...

No pain, DOE Joint Genome Institute gains coveted ergonomics prize with 'Shake 'N Plate'

...head of the DOE JGI Sequencing Department. "Since mounting this campaign, we have experienced a steady decrease in OSHA-recordable ergonomic injuries while bottom-line productivity and morale have risen." "Our science is absolutely dependent on maintaining a safe work environment," said Rubin. "To ensure ...

Elevated autoantibodies linked to preeclampsia

...cause of preeclampsia remains unknown, evidence is mounting that the disorder relates to poor formation and placement of the placenta combined with underlying maternal factors including insulin resistance, obesity and inflammation that are magnified during the physiological stress of pregnancy. Elevated lev...

On January 10, 2007, Dr. Sheila Fraser of St. James's University Hospital in Leeds, U.K. delivered a paper at the Society of Academic & Research Surgery Conference in Cambridge, U.K., in which she described a test tube experiment f...

Complexity constrains evolution of human brain genes

... organism. The authors attribute the slowdown to mounting complexity of interactions within the brain. "We know that proteins with more interacting partners evolve more slowly," Wu said. "Mutations that disrupt existing interactions aren't tolerated." Although the gene sequences from human and chimpanzee ...

What it means to be human

...ially created software tools. The results support mounting evidence that the simple duplication and loss of genes has played a bigger role in our evolution than changes within single genes. Cristianini and his research partners examined 110,000 genes in 9,990 gene families that are shared by humans, common c...

"Our results support mounting evidence that the simple duplication and loss of genes has played a bigger role in our evolution than changes within single genes," Hahn said. That finding complements reports by University of Colorado and University of Michigan researchers in the ...

One of the study's co-authors, oncologist Wafik El-Deiry, M.D., Ph.D., of the University of Pennsylvania, is internationally prominent for his studies of the p53 protein. "This work ...

Study aims to identify schizophrenics at risk for type 2 diabetes

"The brain has this incredibly complex development where cells are ...

Role of protein in immune response may aid HIV research

...e front line in defending the body from infection, mounting a defense long before the body's main immune system responds. The IU School of Medicine Northwest scientists report that various organs mount different defensive responses with PGLYRP when exposed to bacteria. The skin produces these proteins only ...

Male praying mantids prefer not to be victims of sexual cannibalism

...their approach, increasing courtship behavior, and mounting from a greater and possibly safer distance. "This shows that male mantids actively assess variation in risk and change their behavior to reduce the chance of being cannibalized," explains Brown. "Males are clearly not complicit, and the act of s...

Case Western Reserve University researchers find protein associated with brain cell death

"We have recently shown that microglia employ a multi-receptor cell surface complex to detect and respond to amyloid beta fibrils," the researchers write....

Damaged Iraq marshes show renewed signs of life
