Researchers find possible genetic clues to organ development, birth defects
Using cutting-edge time-lapse photography, University of Southern California (USC) researchers have discovered clues to the development of the head at the cellular level, which could point scientists to a better understanding of how organs and birth defects form in humans.

Researchers identify genetic root to early-onset prostate cancer
Prostate cancer is often considered an elderly man's disease, and little is known about the approximately 2% of cases that arise in men who are aged 50 years or younger. Research published in the February 11th issue of the Cell Press journal Cancer Cell uncovers the genetic origin of such early-onset prostate cancer.

Mouse model improves understanding of clear cell sarcoma
Geneticists led by University of Utah Nobel Prize Laureate Mario R. Capecchi, Ph.D., have engineered mice that develop clear cell sarcoma (CCS), a significant step in better understanding how this rare and deadly soft tissue cancer arises. The mouse model also can potentially speed the development of drugs to target genes that must be activated for the cancer to form.

Protein paves the way for correct stem cell differentiation
A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. If the regulation is lost, specialized cells cannot develop correctly during development. In adulthood, the specialized cells may forget their identity and develop into cancer cells. Research from BRIC, University of C

Colon cancer exhibits a corresponding epigenetic pattern in mice and humans
Tumourigenesis is driven by genetic alterations and by changes in the epigenome, for instance by the addition of methyl groups to cytosine bases in the DNA. A deeper understanding of the interaction between the genetic and epigenetic mechanisms is critical for the selection of tumour biomarkers and for the future development of therapies.

Research has shown that mutations in the psen1 gene are common in the familial forms of Alzheimer's disease, and the Presenilin-1 protein that the gene encodes is known to be involved in the cleavage of the amyloid precursor protein. In Alzheimer's disease the amyloid precursor protein is not cleaved the normal way, and the protein accumulates in the brain damaging neuronal tracts and neurons. It

Black silicon can take efficiency of solar cells to new levels
Scientists at Aalto University, Finland, have demonstrated results that show a huge improvement in the light absorption and the surface passivation on highly absorbing silicon nanostructures. This has been achieved by applying atomic layer coating. The results advance the development of devices that require high sensitivity light response such as high efficiency solar cells.
