VALLEY SPRINGS, Calif., April 29 (UPI) -- Police in Valley Springs, Calif., said they believe they found fingerprints and DNA evidence at the home of an 8-year-old girl who was stabbed to death.

Leila Fowler was found covered with stab wounds Saturday by her 12-year-old brother. The boy also found an intruder inside the family's home, and the man ran away.

Leila was later pronounced dead at a hospital. An autopsy is scheduled for Monday, CNN reported.

After a thorough search of the Valley Springs home, police said they think they found fingerprints and DNA evidence from the intruder, who they described as a white or Hispanic male with long gray hair, KCRA-TV, Sacramento, reported Sunday.

The man is 6 feet tall with a muscular build and was last seen wearing a black long-sleeved shirt and blue pants.

Calaveras County sheriff's deputies stepped up security at nearby schools and bus stops after the attack, CNN said.

Grief counselors were sent to Leila's elementary school and a candlelight vigil is planned for Tuesday, KCRA reported.

Dr James Watson said it is very important to make science appealing to young people

The Nobel Prize-winning scientist who co-discovered the structure of DNA 60 years ago has said Ireland cannot be a success in science unless it knows as much as other nations.

Dr James Watson, 86, said the investment made in research in Ireland over the past 40 years is beginning to pay off andthere are some very good scientists in the country.

He was asked about comments he made last month in San Diego, where he referred to ignorance being the curse of the Irish.

Dr Watson said what he meant was that historically Irish people lacked knowledge.

He said that he was not implying that Irish people were stupid.

Ireland just has to be good at technology, he said, and that takes a long time and requires a serious university system.

He said it is very important to make science appealing to young people.

Dr Watson, who is now engaged in cancer research, said he is convinced genetics will not lead to the discovery of a cure for cancer, but chemistry will.

On the level of investment in cancer research, he said he does not believe that too much is being spent on it.

DNA scientist stresses importance of knowledge

As a memorial is unveiled to one of the two scientists who discovered the structure of DNA 60 years ago, Australian scientists paid tribute to them.

A memorial to British biologist Francis Crick will be unveiled by American James Watson at Cambridge University on Thursday.

The two colleagues described the double-helix structure of DNA in a seminal paper published in the journal Nature on April 25, 1953.

Their work set the stage for a molecular revolution, opening up vast new avenues of understanding about the genetic code, or 'Book of Life'.

Suzanne Cory, president of the Australian Academy of Science, said Professor Crick and Dr Watson's discovery was an epic moment in the history of science.

'It was learning about DNA at university that inspired me to become a scientist,' Professor Cory said in a statement.

'I wrote to Francis Crick asking whether he would take me on as a PhD student and, to my amazement, he said yes.

'The time I spent in his department at the famed MRC Laboratory of Molecular Biology in Cambridge marked me indelibly.'

Jerry Adams, from the Walter and Eliza Hall Institute of Medical Research, worked with Watson at Harvard in the years following the discovery.

'The deciphering of the 'Genetic Code' in the late 1960s was a milestone,' Professor Adams said.

DNA discovery marks 60th anniversary

On the diamond jubilee of the double helix, we should admit that we don't fully understand how evolution works at the molecular level, suggests Philip Ball

This week's diamond jubilee of the discovery of DNA's molecular structure rightly celebrates how Francis Crick, James Watson and their collaborators launched the 'genomic age' by revealing how hereditary information is encoded in the double helix. Yet the conventional narrative in which their 1953 Nature paper led inexorably to the Human Genome Project and the dawn of personalized medicine is as misleading as the popular narrative of gene function itself, in which the DNA sequence is translated into proteins and ultimately into an organism's observable characteristics, or phenotype.

Sixty years on, the very definition of 'gene' is hotly debated. We do not know what most of our DNA does, nor how, or to what extent it governs traits. In other words, we do not fully understand how evolution works at the molecular level.

That sounds to me like an extraordinarily exciting state of affairs, comparable perhaps to the disruptive discovery in cosmology in 1998 that the expansion of the Universe is accelerating rather than decelerating, as astronomers had believed since the late 1920s. Yet, while specialists debate what the latest findings mean, the rhetoric of popular discussions of DNA, genomics and evolution remains largely unchanged, and the public continues to be fed assurances that DNA is as solipsistic a blueprint as ever.

The more complex picture now emerging raises difficult questions that this outsider knows he can barely discern. But I can tell that the usual tidy tale of how 'DNA makes RNA makes protein' is sanitized to the point of distortion. Instead of occasional, muted confessions from genomics boosters and popularizers of evolution that the story has turned out to be a little more complex, there should be a bolder admission indeed a celebration of the known unknowns.

DNA dispute A student referring to textbook discussions of genetics and evolution could be forgiven for thinking that the 'central dogma' devised by Crick and others in the 1960s in which information flows in a linear, traceable fashion from DNA sequence to messenger RNA to protein, to manifest finally as phenotype remains the solid foundation of the genomic revolution. In fact, it is beginning to look more like a casualty of it.

Although it remains beyond serious doubt that Darwinian natural selection drives much, perhaps most, evolutionary change, it is often unclear at which phenotypic level selection operates, and particularly how it plays out at the molecular level.

SALT LAKE CITY--(BUSINESS WIRE)--

Co-Diagnostics, Inc., a specialist in personalized medicine and clinical diagnostics, has entered into an agreement with DNA Logix, a leader in the development of molecular diagnostic assays, to acquire certain technologies for genetic analysis in the clinical, industrial, and bio-threat markets.

Molecular diagnostics is the fastest growing segment of the $33 billion U.S. in-vitro diagnostics market. The technology to be acquired is embodied in three patent applications and certain trade secrets that enable high performance DNA testing with superior sensitivity and specificity. The technology facilitates rapid assay development and significantly reduced costs for the end user.

Dwight Egan, President of Co-Diagnostics, Inc., commented: We are pleased to announce this technology acquisition from DNA Logix. DNA Logixs experience in providing the technology for developing molecular diagnostics in the oncology and infectious disease arena is increasingly being recognized by major diagnostic manufacturers and pharmaceutical partners throughout the world. With this technology, we believe our highly efficient assay development capability, combined with superior results and efficient costs, will result in our unique approach to DNA testing being sought after by developers of powerful diagnostics in a wide range of markets.

The technology was created by Brent C. Satterfield, Ph.D., founder of DNA Logix. Prior to founding DNA Logix, Dr. Satterfield helped to found Arcxis Biotechnologies with several of his inventions, including microfluidic sample preparation, diagnostic tests, and probe technologies. One of his more notable inventions was the Tentacle Probe, a new class of DNA diagnostic probe that is up to 200 times faster than other probes, up to 10,000 times more specific in high concentrations of contaminant, and up to 13 times more robust in extreme temperature conditions. His diagnostic design abilities have been utilized by a number of large organizations, including the directors and managers of Sandia National Laboratories, United States Army Medical Research Institute of Infectious Disease, Department of Homeland Security, National Biodefense Analysis and Countermeasures Center, and numerous others.
