Genetic abnormalities in benign or malignant tissues predict relapse of prostate cancer
While active monitoring of serum prostate specific antigen (PSA) levels in men over 50 has greatly improved early detection of prostate cancer, prediction of clinical outcomes after diagnosis remains a major challenge. View More (2012-05-07)
Measuring progesterone receptor expression to improve hormone-receptor-positive cancer management
American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they report at the 4th IMPAKT Breast Cancer Conference. View More (2012-05-03)
Range of diagnostic spinal fluid tests needed to differentiate concurrent brain diseases
Teasing out the exact type or types of dementia someone suffers from is no easy task; neurodegenerative brain diseases share common pathology and often co-occur. Researchers from the Perelman School of Medicine at the University of Pennsylvania are continuing efforts to differentiate diseases, such as Alzheimer's disease (AD) from frontotemporal lobar degeneration (FTLD), as FTLD is often...

New findings, imaging may aid diagnosis of concomitant AD in patients with Parkinson's disease dementia
Dementia is a frequent complication of Parkinson's disease (PD), but it is clinically impossible to distinguish PD dementia (PDD), which develops from the progression of the Lewy body pathology that underlies PD, from PD with coexistent Alzheimer's disease (PDAD). View More (2012-04-17)
Ultra-Sensitive Electrical Biosensor Unlocks Potential for Instant Diagnostic Devices
A new quantum mechanical-based biosensor designed by a team at University of California, Santa Barbara offers tremendous potential for detecting biomolecules at ultra-low concentrations, from instant point-of-care disease diagnostics, to detection of trace substances for forensics and security.

Genetic adaptation of fat metabolism key to development of human brain
About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. View More (2012-04-13)
Study Finds Significant Skull Differences Between Closely Linked Groups
In order to accurately identify skulls as male or female, forensic anthropologists need to have a good understanding of how the characteristics of male and female skulls differ between populations. A new study from North Carolina State University shows that these differences can be significant, even between populations that are geographically close to one another. View More (2012-04-13)
Rapid method of assembling new gene-editing tool could revolutionize genetic research
Development of a new way to make a powerful tool for altering gene sequences should greatly increase the ability of researchers to knock out or otherwise alter the expression of any gene they are studying. View More (2012-04-10)
Pulse pressure elevation could presage cerebrovascular disease in Alzheimer's patients
Researchers at the University of California, San Diego and Veterans Affairs San Diego Healthcare System have shown that elevated pulse pressure may increase the risk of cerebrovascular disease (CVD) in older adults with Alzheimer's disease (AD). View More (2012-04-09)
Facilitating the work of forensic scientists
The University of the Basque Country's (UPV/EHU) METABOLOMIPs group develops analytical methods to help characterize different types of substances, and focuses on the forensic sciences, in particular. View More (2012-04-04)
Exploding dinosaur hypothesis implodes
The pregnant ichthyosaur female from Holzmaden (Germany) that perished 182 million years ago puzzled researchers for quite some time: The skeleton of the extinct marine reptile is almost immaculately preserved and the fossilized bones of the mother animal lie largely in their anatomical position.

Health groups issue cervical cancer screening guidelines
The American Cancer Society (ACS), the American Society for Colposcopy and Cervical Pathology (ASCCP), and the American Society for Clinical Pathology (ASCP) have released new guidelines for the prevention and early detection of cervical cancer. View More (2012-03-15)
The loss of a protein makes 'jump' the tumor to the lymph node
Metastasis is responsible for 90% of deaths in patients with cancer. Understanding the mechanisms responsible for this process is one of the top goals of cancer research. View More (2012-03-07)
Fewer women need repeat breast cancer surgeries with new service at University of Michigan
Nearly one in three women who have breast cancer surgery will need to return to the operating room for additional surgery after the tumor is evaluated by a pathologist. View More (2012-02-29)
Experts recommend measures to reduce human error in fingerprint analysis
A new report by the National Institute of Standards and Technology (NIST) and the Department of Justice's National Institute of Justice (NIJ) has documented 149 potential sources of human error in the analysis of crime scene fingerprints. View More (2012-02-23)

New crime-fighting tools aim to deter and nab terrorists
Fingerprints, ballistics, DNA analysis and other mainstays of the forensic science toolkit may get a powerful new crime-solving companion as scientists strive to develop technology for "fingerprinting" and tracing the origins of chemical substances that could be used in terrorist attacks and other criminal acts.
