Some smokers have genetic predisposition to develop chronic obstructive pulmonary disease

Some people have a genetic variation that makes them more susceptible to chronic obstructive pulmonary disease (COPD) if they smoke tobacco, according to new research from Wake Forest University School of Medicine and colleagues.

microRNA may play an important role in psoriasis and eczema

A research team at the Swedish medical university Karolinska Institutet has shown for the time that microRNA, small RNA molecules, may play an important role in the development of inflammatory skin diseases such as psoriasis and atopic eczema.

Startling discovery on the development of human embryonic stem cells

In this week's Nature, researchers of the McMaster Cancer and Stem Cell Research Institute show that human embryonic stem (ES) cells can actually produce distinctive niche cells, which then release stem-cell nourishing proteins to help keep their parents ticking over.

New method to estimate sickle cell disease severity

Researchers from Boston University School of Medicine (BUSM) and Boston University School of Public Health (BUSPH) have developed a method to estimate sickle cell disease severity and predict the risk of death in people with this disease.

New evidence of very recent human adaptation

A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa.

Chemotherapy may benefit all women with a BRCA1 mutation

Breast cancer patients who possess one of the so-called "breast cancer" or BRCA genetic mutations do not have a higher risk of dying than patients with no BRCA mutations, according to a detailed study by researchers at the Technion-Israel Institute of Technology and the University of Toronto.

New advance in search for effective treatment for human liver cancer

Researchers from the University of Pittsburgh School of Medicine report a significant new advance in the search for an effective treatment for human liver cancer in the July issue of Molecular Cancer Therapeutics.

Ago2 and hematopoiesis

Argonaute 2 (Ago2) is unique among its family: It is the only one of the four mammalian Argonaute proteins that exhibits endonuclease 'slicer' activity (facilitation of miRNA-guided cleavage of target mRNA).

New model of early biological evolution

In a study publishing in PLoS Computational Biology, Shakhnovich et al present a new model of early biological evolution , the first that directly relates the fitness of a population of evolving model organisms to the properties of their proteins.

New genetic function involved in embryo development in organisms

Research aimed at understanding the mechanisms underlying embryo development has taken a step forward thanks to collaborative work between biologists specialized in the study of the fruit fly (Drosophila melanogaster) and scientists specialized in the design of mathematical models that simulate the functioning of biological systems.

Master switch for the production of brown fat discovered

Researchers at Dana-Farber Cancer Institute have identified a long-sought "master switch" in mice for the production of brown fat, a type of adipose tissue that generates heat and counters obesity caused by overeating.

Neural stem cells for Parkinson's disease

A University of South Florida neuroscientist reports that the cutting-edge research study of human stem cells in primates with Parkinson's disease is compelling on several fronts , particularly how the transplanted cells did their job of easing disease symptoms.

Discovery of gallstone gene

Scientists at the University of Bonn, together with colleagues from Romania, have discovered a gene variant that significantly increases the risk of developing gallstones (Hepatology No. 46, 11 July 2007, DOI 10.1002/hep.21847).

3-D microscopic views of tiny mouse brains available online

A multi-institutional consortium including Duke University has created startlingly crisp 3-D microscopic views of tiny mouse brains - unveiled layer by layer - by extending the capabilities of conventional magnetic resonance imaging.

Magnetic nano tweezers show how cancer drug works

The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.
