Researchers aim to over-stress already taxed mantle cell lymphoma cells
Cancer cells are already stressed by the fast pace they require to grow and spread and scientists believe a little more stress just may kill them. view more (2008-11-11)
Largest-ever database for liver proteins may lead to treatments for hepatitis
Scientists at a group of 11 research centers in China are reporting for the first time assembly of the largest-ever collection of data about the proteins produced by genes in a single human organ. view more (2009-11-12)
Microtubule protein interactions visualized en masse
In a new study published online in the open access journal PLoS Biology, Philipp Niethammer, Eric Karsenti, and colleagues investigate the regulation of microtubule dynamics via application of their new method, called visual immunoprecipitation (VIP), which enables simultaneous visualization of multiple protein interactions in cell extracts. view more (2007-01-16)
Anthrax inhibitor counteracts toxin, may lead to new therapeutics
Researchers from Rensselaer Polytechnic Institute and the University of Toronto have designed a nanoscale assembly of molecules that successfully counteracts and inhibits anthrax toxin in animal and laboratory experiments. view more (2006-04-24)
Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed
During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. view more (2007-12-10)
A New Vision For Human Security (p 1665)
This week's editorial discusses the implications for global health on a recently published report by the Commission on Human Security-which defines security in terms of human development, human rights, and democracy-and highlights WHO's vital future role in ensuring the report is implemented. The report states that "poverty-related health... view more... (2003-05-14)
Jules Verne ATV atop launcher
Jules Verne, the first Automated Transfer Vehicle, has been encapsulated in its huge fairing on top of the Ariane 5 launcher. view more (2008-02-29)
Evolution in the Nanoworld
The automatic molecular assembly and selection steps exhibited by the molecules, which start as random mixtures, demonstrates a fundamental step in the evolution of life. view more (2007-10-31)
Lotus effect shakes off dirt
The lotus - a flowering wetland plant native to Asia - may not at first glance be of interest to the nanotechnologist. But researchers at German chemical company BASF are developing a spray-on coating that mimics the way lotus leaves repel water droplets and particles of dirt. The story is reported on nanotechweb.org, the Institute of Physics'... view more... (2002-11-08)
New insights into how the oncogenic protein c-Myc regulates cell growth
New findings by Swedish and German scientists on the regulation of cellular growth are published in the March issue of Nature Cell Biology. view more (2005-02-20)
Researchers map infectious hepatitis B virus
Using electron cryomicroscopy and computer image analysis, the scientists visualized two intermediate forms of the virus that exist within infected cells. In addition, they were able to determine a three-dimensional map by analysis of infectious hepatitis B virus isolated from patient blood samples. view more (2006-06-26)
Opals manufactured by beetles
The gemstone opal could be manufactured synthetically copying a technique employed by a beetle to control the appearance of its outer shell. Researchers from the Department of Zoology at the University of Oxford have discovered the first case of opal in an animal, in this case in the weevil Pachyrhynchus argus, found in forests in north-eastern... view more...

Researchers assemble second non-human primate genome
A multi-center team has deposited the draft genome sequence of the rhesus macaque monkey into free public databases for use by the worldwide research community, the National Human Genome Research Institute (NHGRI). view more (2006-02-10)
Atomic structure of the mammalian 'fatty acid factory' determined
Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. view more (2008-09-05)
Angled gantry technique reduced breast radiation exposure by 50 percent
A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers. view more (2008-12-04)
Proteomics Center Devises Method for Assigning Probabilities to Human Protein Interactions
The Stowers Institute's Proteomics Center has published a novel method of using normalized spectral counts derived from a series of affinity purifications analyzed by mass spectrometry (APMS) to generate a probabilistic measure of the preference of proteins to associate with one another. view more (2008-01-25)
Phoenix Mars mission spacecraft lands at Kennedy Space Center
A U.S. Air Force C-17 cargo aircraft carried NASA's Phoenix Mars Lander spacecraft Monday, May 7, from Colorado to Florida, where Phoenix will start a much longer trip in August. view more (2007-05-09)
Study finds particles, molecules prefer not to mix
In the world of small things, shape, order and orientation are surprisingly important, according to findings from a new study by chemists at Washington University in St. Louis. view more (2009-05-05)
Are nanobots on their way?
The first real steps towards building a microscopic device that can construct nano machines have been taken by US researchers. Writing in the peer-reviewed publication, International Journal of Nanomanufacturing from Inderscience Publishers, researchers describe an early prototype for a nanoassembler. view more (2008-04-29)
Deep-sea oil rigs inspire MIT designs for giant wind turbines
An MIT researcher has a vision: Four hundred huge offshore wind turbines are providing onshore customers with enough electricity to power several hundred thousand homes, and nobody standing onshore can see them. view more (2006-09-19)
