Gaps in intestinal barrier could cause Crohn's disease
Scientists at the University of Liverpool believe gaps in the intestinal barrier could be a cause of inflammatory diseases of the gut such as Crohn's Disease. view more (2005-09-16)
Discovery of key malaria proteins could mean sticky end for parasite
Scientists funded by the Wellcome Trust have identified a key mechanism that enables malaria-infected red blood cells to stick to the walls of blood vessels and avoid being destroyed by the body's immune system. The research, published today in the journal Cell, highlights an important potential new target for anti-malarial drugs. view more (2008-07-10)
The nanoworld of corrosion
The effect of corrosion has an impact on about 3% of the world's Gross Domestic Product. From a positive point of view, however, chemical attack of metal surfaces may result into surface nano-structures with very interesting technological applications such as catalysts and sensors. view more (2006-02-10)
Discovering New Regulators Of The Immune System
London, U.K. and South San Francisco, CA, 15th September 2003. In an attempt to find new regulators of the immune system, a team of researchers at Rigel Pharmaceuticals, Inc. have created a successful method for discovering molecules that are involved in signalling pathways. As published this week in the Journal of Biology, the team conducted a... view more... (2003-09-12)
Photoelectric cells classified
Currently there is great talk of renewable energies and, amongst these solar energy is highly important. In order to harness and utilise this form of energy there are many technologies available of which one is solar panels. These panels are made up of photoelectric cells (the 80-100 little square units in any one panel). Photoelectric cells are... view more... (2003-01-31)
Multivariate coupling mechanism of superhydrophobicity on NOCTUIDAE moth wing surface
Research carried out by Key Laboratory for Terrain Machine Bionics Engineering of Ministry of Education, Jilin University in Changchun, China, has shown that the co-coupling effect of scale biomaterial, micron-class shape and nanometer-class structure of vertical gibbosities of scale can induce surface hydrophobicity and self-cleaning function of... view more...

Lab-on-a-Chip Homes in on How Cancer Cells Break Free
Johns Hopkins engineers have invented a method that could be used to help figure out how cancer cells break free from neighboring tissue, an "escape" that can spread the disease to other parts of the body. view more (2009-03-19)
Rong Li Lab demonstrates the process of mammalian egg maturation
he Rong Li lab team has answered an important question about how mammalian eggs undergo maturation through an intricate process of asymmetric cell division. The team discovered a novel pathway by which chromatin exerts command on the cell membrane to produce a specialized machinery used for cell division. view more (2007-02-06)
Cellular pathway yields potential new weapon in vaccine arsenal
When a cell has to destroy any of its organelles or protein aggregates, it envelopes them in a membrane, forming an autophagosome, and then moves them to another compartment, the lysosome, for digestion. Two years ago, Rockefeller University assistant professor Christian Münz showed that this process, called autophagy, sensitizes cells for... view more... (2006-12-27)
Scientists unveil mysteries of plasma jets on the Sun
Scientists at the University of Sheffield and Lockheed Martin Solar and Astrophysics Lab have solved a 127-year-old problem about the origin of supersonic plasma jets (spicules) which continuously shoot up from the Sun. Their findings are published in today's edition of Nature. Spicules, are jets of gas or plasma that are propelled upwards from... view more... (2004-07-29)
Tiny holes offer surprising insights
Researchers from Berlin and Seoul store light in plasmonic crystals view more (2005-03-04)
Einstein researchers discover gene mutations linked to longer lifespans
Mutations in genes governing an important cell-signaling pathway influence human longevity, scientists at the Albert Einstein College of Medicine of Yeshiva University have found. view more (2008-03-05)
Research re-examines strong hurricane studies
Researchers at the Georgia Institute of Technology have released a study supporting the findings of several studies last year linking an increase in the strength of hurricanes around the world to a global increase in sea surface temperature. view more (2006-03-17)
New paper sheds light on bacterial cell wall recycling
A new paper by a team of researchers led by Shahriar Mobashery, Navari Family Professor of Life Sciences at the University of Notre Dame, provides important new insights into the process by which bacteria recycle their cell wall. view more (2008-09-09)
Protein splicing upsets the DNA colinearity paradigm
Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein. view more (2006-09-08)
New research reveals how cranberry products prevent urinary tract infections
Chemicals present in cranberries-and not the acidity of cranberry juice, as previously thought-prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food, a peer-reviewed journal published by Mary Ann Liebert, Inc. view more (2009-03-10)
Mutation protects from HIV - and increases risk of hepatitis C
More than 40 million people worldwide are infected with the human immunodeficiency virus HIV. In Africa alone this incurable immune deficiency caused more than two million deaths last year. Yet some people are resistant to infection: the reason for this is a mutation in their DNA which prevents the HIV virus from invading certain immune cells and... view more... (2002-07-17)
The development of stem cells -- not only which and where but also WHEN
Yet another stride has been taken on the road to knowledge about the development of the nervous system. For the first time factors have been uncovered that decide when a cell is to develop into another cell. During the last ten years much progress has been made in finding out what determines how various types of nerve cells develop from a stem... view more... (2003-03-20)
Study identifies molecule essential for proper localization of blood stem cells
Scientists at the Massachusetts General Hospital (MGH) Center for Regenerative Medicine and the Harvard Stem Cell Institute (HCSI) have defined a molecule that dictates how blood stem cells travel to the bone marrow and establish blood and immune cell production. view more (2006-01-16)
