Scientists provide the first comprehensive picture of minimal cell

What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system? These are just some of the questions that scientists in a partnership between the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and the Centre de Regulacio Genòmica (CRG) in Barcelona, Spain, set out to address.

Study on placebo effect

A short time ago, Swedish scientists published a paper suggesting the existence of a genetic disposition to respond to placebo, thus giving rise to debate in the media about a possible "placebo gene." In the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106[46]: 751-5), Matthias Breidert and Karl Hofbauer summarize the most recent data about placebos.

Researchers devise new tools for typing cells from children with acute lymphatic leukemia

Researchers at Uppsala University and University Children's Hospital in Uppsala have devised powerful new tools for typing cells from children with acute lymphatic leukemia and for prediction of how children with leukemia will respond to chemotherapy.

B cells and their antibodies defend against microbes and control commensal microflora

Microbes populated the earth long before any eukariotic cell. Therefore, in order to survive, mono and multi-cellular organisms had to develop mechanisms of adaptation, cohabitation and defense against bacteria, fungi and viruses. One of these mechanisms is mediated by immunoglobulins in the serum and at mucosal surfaces.

Scientists demonstrate stem cells heal lungs of newborn rats; study anticipated to benefit premature babies

Dr. Bernard Th-baud lives in two very different worlds. As a specialist in the Stollery Children's Hospital's Neonatal Intensive Care Unit at the Royal Alexandra Hospital, he cares for tiny babies, many of whom struggle for breath after being born weeks before they are due.

Sexual selection to greatly enlarge the scope for adaptive speciation, finds new research

Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of his famous book, 'On the Origin of Species', debate still continues on the mechanisms of speciation.

New approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres discovered

Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident.

Experts say vitamin D assists body's immune system to fight against H1N1

The world's leading vitamin D experts say that raising your levels of "the sunshine vitamin" this winter might be the best way to help your body naturally raise its resistance to all forms of the flu virus - including the H1N1 swine flu virus.

BodyLogicMD opens 13 new bioidentical hormone specialty practices in 2009

For many businesses, 2009 has been a painful year. Not so for BodyLogicMD. The nation's largest and fastest growing network of expert physicians specializing exclusively in medically supervised bioidentical hormones has grown the number of physicians in its network since November 2008 - from 21 to 36 physicians - and is in progress to add more physician-owned centers, including one in Puerto Rico, by the end of this year.

Researchers identify a set of molecular brakes that stabilize the developing brain's circuitry

Researchers at the Stanford University School of Medicine have identified a set of molecular brakes that stabilize the developing brain's circuitry. Moreover, experimentally removing those brakes in mice enhanced the animals' performance in a test of visual learning, suggesting a long-term path to therapeutic application.

GIS scientists publish the first genetic historical map of Han Chinese

The first genetic historical map of the Han Chinese, the largest ethnic population in the world, as they migrated from south to north over evolutionary time was published online today by the American Journal of Human Genetics by scientists at the Genome Institute of Singapore (GIS).

Wnt and EGFR signaling pathways interact to promote tumor cell invasion and metastasis

Two signaling pathways essential to normal human development - the Wnt/Wingless (Wnt) and epidermal growth factor receptor (EGFR) pathways - interact in ways that can promote tumor cell invasion and metastasis, researchers from The University of Texas M. D. Anderson Cancer Center report in the Nov. 25 issue of Molecular Cell.

Scientists offer first genetic proof of new and rational treatment for osteoporosis

The so-called RANK protein and the molecule that binds to it, the RANK ligand or RANKL, form a focus of the work of Josef Penninger, director of the Institute of Molecular Biotechnology (IMBA) in Vienna. In 1999 his group deleted the RANKL gene from mice and showed that the RANK/RANKL system was the "master regulator" governing bone loss (Kong et al. 1999 Nature 402, 304-309).
