Researchers at New York University are working to develop molecular delivery vehicles that can be used to transport nucleic acids into diverse cell types, which may lead to eventual applications in genetic therapies.   view more (2006-11-14)

Major cancer study aims to identify protein markers for early-stage disease
A team led by Bay Area scientists is one of five nationwide to receive a major grant from the National Cancer Institute (NCI) to refine and standardize the technologies for identifying biomarkers in the blood - specific proteins, and the patterns they make - for the early detection of cancer.   view more (2006-09-29)

USC researchers show that molecular markers predict tumor recurrence
Researchers at the University of Southern California (USC) have identified specific molecular markers that may help to predict tumor recurrence in stage II and III colon cancer patients.   view more (2007-06-06)

The closest look ever at native human tissue
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory [EMBL] have visualised proteins responsible for cell-cell... view more (2007-12-06)

Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have... view more (2004-10-26)

UIC scientists discover how some bacteria survive antibiotics
Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings, published in the April 24 issue of the journal Molecular Cell, could lead to more effective... view more (2008-05-01)

Plague agent helps UT Southwestern researchers find novel signaling system in cells
The bacterium that causes bubonic plague would seem unlikely to help medical scientists, but researchers at UT Southwestern Medical Center have harnessed it to uncover a new regulatory mechanism that inhibits the immune system.   view more (2006-05-26)

A search for biomarkers for early detection of colorectal cancer
Researchers at the Zhejiang University, Hangzhou have discovered that mimecan and Thioredoxin Domain-Containing Protein 5 (TXNDC5) were differentially expressed in colorectal adenoma.   view more (2007-09-25)

Novel hydrogel systems for dentin regeneration
Dental caries, or tooth decay, continues to be the most prevalent infectious disease in the world, presenting significant public health challenges and socio-economic consequences.   view more (2008-07-07)

Synchrotron radiation illuminates how babies' protective bubble bursts
Researchers at the University of Reading, School of Pharmacy have developed an important new technique to study one of the most common causes of premature birth and prenatal mortality.   view more (2007-11-07)

Breast cancer treatment resistance linked to signaling pathway
Activation of the Src signaling pathway may cause resistance to standard medical treatment in some patients with breast cancer, and inhibition of this pathway holds the potential to overcome that resistance, according to data presented here at the American Association for Cancer Research Molecular... view more (2008-09-23)

Physics and biology team up to tackle protein folding debate
A team of researchers from EPFL, (Ecole Polytechnique Fédérale de Lausanne), the University of Lausanne, Northwestern University and Tel Aviv University bring biology and statistical physics together to answer the question of how molecular chaperones fold, unfold and pull proteins... view more (2006-04-04)

Molecular detectors may refine cancer treatment
University of Florida researchers have successfully used molecular probes to detect subtle differences in leukemia cells from patient samples, an achievement that could lead to more effective ways to diagnose and treat cancer.   view more (2007-07-20)

Study shows blood markers can help choose best dose for antiangiogenic drugs
Scientists at Sunnybrook have new information that may help to improve the use of anti-cancer drugs designed to block the growth of new blood vessels in tumors, a process called angiogenesis that is critical to tumor growth.   view more (2007-10-26)

A new focus for the mechanism of nerve growth
Researchers at Yale shed new light on the mechanism of nerve cell growth by identifying novel functions for a molecular "motor" protein, myosin-II, according to an article in the March issue of Nature Cell Biology.   view more (2006-03-20)

Researchers uncover new mechanism of tumor suppressor
Researchers from the University of Colorado-Denver and Health Sciences Center and Stanford University have discovered a molecular mechanism that explains how cells respond to DNA damage and other acute stresses, and if disrupted can cause cancer.   view more (2006-05-22)

Environmental toxicants like lead, mercury target stem cells
Low levels of toxic substances cause critical stem cells in the central nervous system to prematurely shut down. That is the conclusion of a study published today in the on-line journal PLoS Biology.   view more (2007-02-06)

Double research boost for tissue engineering community
The UK Department of Trade and Industry has recently awarded two biomaterial research projects to a consortium comprising the University of Brighton (School of Pharmacy and Biomolecular Sciences), the National Physical Laboratory and Queen Mary College, University of London. The projects:... view more (2003-05-29)

Marine bacterium suspected to play role in global carbon and nitrogen cycles
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon.   view more (2005-09-23)

Tiny molecule helps control blood-vessel development, researchers find
The development and repair of heart tissue and blood vessels is intimately tied to a tiny piece of ribonucleic acid (RNA) that is found nowhere else in the body, researchers at UT Southwestern Medical Center have found.   view more (2008-08-13)

Apples, apple juice shown to prevent early atherosclerosis
A new study shows that apples and apple juice are playing the same health league as the often-touted purple grapes and grape juice. The study was published in the April 2008 issue of Molecular Nutrition and Food Research.   view more (2008-05-05)

Building blocks of the future
Structure and properties of carbon nanostructures The discovery in 1985 of fullerenes, tiny carbon balls of nanometer dimensions, ushered in a new era in international science. Only a few years later (1991) scientific interest also started to focus on so-called carbon nanotubes. The discovery of... view more (2002-12-05)

Scientists learn what's 'up' with a class of retinal cells in mice
Harvard University researchers have discovered a new type of retinal cell that plays an exclusive and unusual role in mice: detecting upward motion. The cells reflect their function in the physical arrangement of their dendrites, branch-like structures on neuronal cells that form a communicative... view more (2008-03-28)

EICOS 2004: Journalism meets science: Join a lab and experience science as it happens!
EICOS, the "European Initiative for Communicators of Science", again invites journalists from European countries into its "Hands-on Laboratory" and to the "Extended Assignments".
