'Superdense' coding gets denser
The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of "wiggling" and "twisting" of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity for dense coding with linear optics. view more (2008-03-25)
Facial models allow "band-efficient" video communication
Is it possible to combine a three-dimensional wire model of a face with real pictures of the same face? And is it possible to get the computer that is forming the new image to follow the face even when the person in question makes sudden movements or partially covers her face with her hand? These are a couple of the research questions for the... view more... (2002-02-11)
Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA. view more (2006-04-04)

Non-coding RNAs help silence the mammalian transcription
Dr. Shirley Tilghman and colleagues (Princeton University) lend new insight into the mechanism of genomic imprinting, demonstrating a necessary role for a non-coding RNA transcript in the silencing of an imprinted gene cluster in mice. view more (2006-05-15)
MPEG-4 Audio-Visual Solutions One-Stop At Fraunhofer IIS
High-quality video transmission with multi-channel sound through DSL connections finally becomes reality thanks to an up to now unmatched efficiency in audio and video compression. The revolutionary new multimedia technology can be licensed one-stop at Fraunhofer IIS. MPEG-4 Advanced Video Coding AVC allows screen-filling video in good quality at... view more... (2004-06-21)
Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication. view more (2005-09-30)
Early-stage gene transcription creates access to DNA
A gene contained in laboratory yeast has helped an international team of researchers uncover new findings about the process by which protein molecules bind to control sequences in genes in order to initiate gene expression, according to findings reported in the journal Nature. view more (2008-10-07)
Breast density associated with increased risk of cancer recurrence
A new study finds that women treated for breast cancer are at higher risk of cancer recurrence if they have dense breasts. Published in the December 15, 2009 issue of Cancer, a peer-reviewed journal of the American Cancer Society, the study's results indicate that breast cancer patients with dense breasts may benefit from additional therapies... view more...

'Pregnant' protein-coding genes carry RNA 'babies'
Scientists from the Chinese Academy of Sciences have performed a comprehensive analysis of small, non-protein-coding RNAs in the model nematode, C. elegans. view more (2006-01-10)
Identification of Functional SNPs - Advances in Determining Genetic Susceptibility to Disease
Researchers at Oxford University's Wellcome Trust Centre for Human Genetics have developed a methodology to evaluate concurrently the functional significance of the millions of non-coding polymorphisms that exist in the human genome. Ultimately, this method will aid the progress in determining humans' genetic susceptibility to disease. One of the... view more... (2003-04-07)
The role of hormone replacement therapy in breast cancers detected between screenings
Research from the Cancer Registry of Norway has revealed that a higher proportion of women who discover they have breast cancer between mammographic screenings have also used HRT (hormone replacement therapy) at some point in their lives, the 3rd European Breast Cancer Conference heard today (Wednesday 20 March). In addition, these women tend to... view more... (2002-03-18)
DAB 5.1 Surround Live Premiere at Medientage 2004
Fraunhofer Institute for Integrated Circuits IIS introduces its novel Spatial Audio Coding technology, which enables 5.1 Surround Sound for Digital Audio Broadcasting DAB. The Bayerische Rundfunk (BR) and Bayern Digital Radio (BDR) broadcast the first 5.1 program over DAB live on "Bayern 4 Klassik" during the Medientage event in Munich. A DAB... view more...

UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
APEX reveals glowing stellar nurseries
Illustrating the power of submillimetre-wavelength astronomy, an APEX image reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimetre light is the key to revealing some of the coldest material in the Universe,... view more... (2008-11-12)
Evolutionarily preserved mechanism governs use of genes
Researchers at Uppsala University have found that the protein coding parts of a gene are packed in special nucleosomes. The same type of packaging is found in the roundworm C elegans, which is a primeval relative of humans. view more (2009-08-18)
New gene regulation mechanism discovered
Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection. view more (2005-10-21)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
Computer-aided detection with computed radiography effective in detecting breast cancer
The use of computer-aided detection (CAD) with computed radiography (CR) is effective in the detection of breast cancer, according to a recent study conducted by radiologists at George Washington University Medical Center in Washington, DC and iCAD in Nashua, NH. view more (2007-05-07)
Chicken genome gives insights into human genome
The draft sequence of the wild chicken, Gallus gallus, will be published in the Dec 9th issue of Nature (cover story). The analysis of this genome is not about getting bigger eggs and tastier chicken - it's giving scientists surprising insights into the human genome. Researchers can use these new data as a tool to identify similar sequences in... view more... (2004-12-06)
