Current policy for complex surgery is misguided
Survival after complex surgery is better not only in hospitals that do a large volume of the same procedure, but also in hospitals that do a large volume of any complex procedure, finds new research. These findings challenge the policy that patients who need a high-risk procedure travel to hospitals that do a high volume of that procedure (known... view more... (2004-03-10)
A new link between nickel, methane gas and the evolution of complex life forms on Earth
A University of Alberta researcher is lead author on a paper that reaches back billions of years to establish a new link between nickel, methane gas and the evolution of complex life forms on Earth. view more (2009-04-09)
Bacteria in disguise cause problems for cystic fibrosis sufferers
Bacteria that cause infections in the lungs of cystic fibrosis patients avoid detection by changing their appearance according to Cardiff University researchers speaking today, Thursday 13 September 2001, at the bi-annual meeting of the Society for General Microbiology at the University of East Anglia. "Pseudomonas aeruginosa bacteria, which... view more... (2001-08-31)
Screening for complex genetic interactions
In a report published online ahead of the January 15th print edition, Dr. David Amberg (SUNY Upstate Medical University) and colleagues have developed a large-scale reverse genetic screen to identify complex haploinsufficient interactions in S. cerevisiae. view more (2006-12-28)
Study questions 'cost of complexity' in evolution
Higher organisms do not have a "cost of complexity" - or slowdown in the evolution of complex traits - according to a report by researchers at Yale and Washington University in Nature. view more (2008-04-01)
Groundbreaking study on complex movements of enzymes
A groundbreaking study has revealed in great detail how enzymes in the cell cooperate to make fat. These enzymes are integrated into a single molecular complex known as fatty acid synthase. This complex is regarded as a potential target for developing new anti-obesity and anti-cancer drugs. view more (2009-02-12)
Too noisy to think: Workplaces that make women sick.
Working in a noisy environment while trying to do a complex job leads to women having high levels of sickness absence. These are the findings of a recent study by Yitzhak Fried from Wayne State University, USA and colleagues in the US and Israel. The study, reported in the Journal of Occupational and Organisational Psychology, published on June... view more... (2002-06-10)
NTU professor discovers method to efficiently produce less toxic drugs using organic molecules
Nanyang Technological University (NTU)'s Associate Professor Zhong Guofu has made a significant contribution to the field of organic chemistry, in particular the study of using small organic molecules as catalysts, in the synthesis process called organocatalysis. view more (2009-07-08)
Mayo clinic discovers new type of sleep apnea
Researchers at Mayo Clinic have identified a new type of sleep apnea they call "complex sleep apnea." The findings will be published in the September issue of the journal Sleep. view more (2006-09-01)
Muscle mass: Scientists identify novel mode of transcriptional regulation during myogenesis
In an upcoming issue of G&D, Drs. Maria Divina Deato and Robert Tjian (HHMI, UC Berkeley) reveal that the formation of an alternative transcriptional core promoter complex directs cell-type specific differentiation during myogenesis. view more (2007-08-20)
A new Eph receptor tyrosine kinase overexpressed in gastric cancer was found
The potential role of Eph receptor and ephrin ligand family in human cancer is receiving increasing attention. Compared with other Eph receptors, EphA4 is distinguished by its ability to bind to both type A ephrins and most type B ephrins. view more (2008-10-29)
Workman Lab characterizes novel regulator of chromosome function
The Stowers Institute's Workman Lab has shed new light on a novel histone acetyltransferase protein complex called ATAC. Acetyltransferases are enzymes that introduce a new acetyl functional group into histone proteins, a process by which all chromosome functions are controlled. view more (2008-03-11)
Enhancement in the precision of high-speed milling of complex parts
The research team led by Norberto López de La Calle at the Department of Mechanical Engineering at the University of the Basque Country, have designed a new model for optimising the high-speed, 3- or 5- axis milling of complex parts. view more (2005-12-14)
ETH Researchers Visualize the Binding of Proteins to the Nuclear Surface
Not only the genetic information of individual cells, but also that of the entire organism is stored within the cell nucleus. Each cell of a multicellular organism, e.g. man, contains the identical DNA sequences. The communication between the cell nucleus and the remainder of the cell is thus decisive for the correct functioning of the cells and... view more... (2003-01-15)
Damage from oxygen may be one cause of Parkinson's disease
Research by neuroscientists at the University of Virginia Health System shows that oxygen free radicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells. view more (2006-05-17)
High-performance computing may improve combustion efficiency
Rising oil prices have revved momentum to develop more efficient combustion systems. But instrumental to this goal is a need to achieve greater understanding of the complex chemical reactions involved in combustion processes. view more (2005-08-30)
K-State professor developing new strategies for delivery of drugs to fight, treat tuberculosis
It has been identified by the World Health Organization as the most dangerous infectious disease, causing more deaths - more than 2 million a year - than any other single infection. "It" is Mycobacterium tuberculosis. view more (2005-08-31)
Targeting the dosage compensation complex
Three independent research papers in the April 1 issue of G&D detail the chromosome-wide binding of the Drosophila dosage compensation complex (DCC) to the single male X chromosome, shedding new light on the mechanism of DCC targeting. view more (2006-03-17)
Oxygen triggered the evolution of complex life forms
Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier than was thought, and in parallel with the availability of oxygen as an energy source. In the largest study to date that does not focus on vertebrates,... view more... (2004-01-22)
Syracuse University research team discovers switch that causes the body to produce cancerous cells
A team of Syracuse University researchers discovered a second molecular switch within the Mixed Lineage Leukemia protein complex that they believe could be exploited to prevent the overproduction of abnormal cells that are found in several types of cancer, including leukemia. view more (2009-09-04)
