Evolution study tightens human-chimp connection
Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes - gorillas and orangutans. view more (2006-01-24)
Computational biochemist uncovers a molecular clue to evolution
A Florida State University researcher who uses high-powered computers to map the workings of proteins has uncovered a mechanism that gives scientists a better understanding of how evolution occurs at the molecular level. view more (2008-09-11)
Correlation between bile duct obstruction and ductal cancer found
When bile duct cancer cells were placed in the liver of animals with bile duct obstruction, they grew more rapidly than identical cells placed in animals without bile duct obstruction. view more (2007-04-30)
Molecular engineers consult nature
Nature has been manipulating structures on the atomic and molecular scale for millions of years, in comparison humans have only been developing these techniques over the last few decades. Molecular engineering builds structures and devices at the smallest scales imaginable, aiming to make better materials, new types of information technologies,... view more... (2002-09-10)
Egg's Energy Stores Key to Preserving Fertility
An immature egg's internal nutrient supply is critical to its survival, an insight that offers a new route to understanding and treating infertility due to egg death. view more (2005-10-07)
Biologists use computers to study bacterial cell division
A group of computational biologists at Virginia Tech have created a mathematical model of the process that regulates cell division in a common bacterium, confirming hypotheses, providing new insights, identifying gaps in what is understood so far, and demonstrating the role of computation in biology. view more (2008-01-25)
Fish vision discovery makes waves in natural selection
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. view more (2009-10-19)
How an enzyme tells stem cells which way to divide
Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists. They've found that one enzyme (aPKC) stands alone and acts as a traffic cop that directs which roads daughter cells will take. view more (2009-05-14)
Scientists reveal fine detail of cell`s energy machinery
A molecular pump that helps to keep cells flush with energy has been visualised by scientists at Imperial College, London. The structure of the pump, a key enzyme in bacterial respiration, reveals for the first time one of the molecular mechanisms that underpins cellular respiration, and confirms a Nobel Prize-winning theory proposed over 40... view more...

Catching the common cold virus: BYU researchers coming down with the rhinovirus genome
A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines. view more (2009-03-17)
Long-term memory controlled by molecular pathway at synapses
Harvard University biologists have identified a molecular pathway active in neurons that interacts with RNA to regulate the formation of long-term memory in fruit flies. view more (2006-01-13)
The University of Bonn starts a new study course "Molecular Biomedicine"
The University of Bonn offers a new 9 semester diploma study course "Molecular Biomedicine", starting in the winter semester 2003/2004. The aim of this programme is to combine molecular approaches, methods and recent insights into life sciences with molecular medicine and knowledge on congenital human disorders. The study course is... view more... (2003-03-13)
Discovery of agile molecular motors could aid in treating motor neuron diseases
Over the last several months, the labs of Yale Goldman, MD, PhD, Director of the Pennsylvania Muscle Institute at the University of Pennsylvania School of Medicine, and Erika Holzbaur, PhD, Professor of Physiology, have published a group of papers that, taken together, show proteins that function as molecular motors are surprisingly flexible and... view more...

Structural polymorphism of 441-residue Tau at single residue resolution
Worldwide almost 30 million suffer from Alzheimer's disease, an irreversible, neurodegenerative condition that is eventually fatal. view more (2009-02-17)
Apolipoprotein(a): A natural regulator of inflammation
In a study to be published in the January 09 issue of Experimental Biology and Medicine, Hoover-Plow and co-workers in seeking to define a role of apo(a) in leukocyte recruitment have identified a novel activity of apo(a) apolipoprotein that may function as a natural and cell specific suppressor of the inflammatory response in vivo. view more (2008-12-29)
Convincing results: Stopping the spread of cancer in the body
A team of Danish researchers have discovered that by blocking a specific enzyme, it is possible to check the spread of cancer in the body. This finding may be the first step towards preventing deaths due to cancer spreading to other parts of the body. The discovery may also help reduce the amount of chemotherapy used. view more (2004-11-22)
Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours. view more (2007-04-11)
Scientists Unlock Possible Aging Secret in Genetically Altered Fruit Fly
Brown University researchers have identified a cellular mechanism that could someday help fight the aging process. view more (2009-01-23)
MSU scientists find new gene that helps plants beat the heat
Michigan State University plant scientists have discovered another piece of the genetic puzzle that controls how plants respond to high temperatures. That may allow plant breeders to create new varieties of crops that flourish in warmer, drier climates. view more (2008-10-07)
Biosensor sniffs out explosives
Temple University School of Medicine researchers have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in the June issue of Nature Chemical Biology. view more (2007-05-09)
