MicroRNA drives both cancer onset and metastasis 2013-07-17

By Beth Israel Deaconess Medical Center

A mere 25 years ago, noncoding RNAs were considered nothing more than "background noise" in the overall genomic landscape. Now, two new studies reveal that one of these tiny noncoding molecules -- microRNA-22 -- plays an outsized role in two typ

Discovered the role of noncoding 5S rRNA in protecting the p53 tumor suppressor gene 2013-07-17

By IDIBELL-Bellvitge Biomedical Research Institute

Researchers have discovered a role for ribosomal 5S RNA in the formation of a complex that regulates the stability of p53. Normally, p53 prevents healthy cells from becoming tumorigenic.

Computer programs improve fingerprint grading 2013-07-17

By Penn State

Subjectivity is problematic when evaluating fingerprints, and quality is in the eye of the examiner. But three computer programs used together can give fingerprint grading unprecedented consistency and objectivity, according to new research.

Adverse effects of phthalates on ovarian response to IVF 2013-07-17

By European Society of Human Reproduction and Embryology

Phthalates are among a group of industrial chemicals shown in some studies to have adverse effects on reproductive health and development, particularly in the male. As such, they have been collectively defined as "endocrine disruptors", and prop

Long-held assumption of gene expression in embryonic stem cells challenged 2013-07-17

By Whitehead Institute for Biomedical Research

Researchers have determined that the transcription factor Nanog, which plays a critical role in maintaining the self-renewal of embryonic stem cells, is expressed in a manner similar to other pluripotency markers. This finding contradicts the field&#8

Unique epigenomic code identified during human brain development 2013-07-17

By Salk Institute

Experience of parents with their children and teachers with their students demonstrate how kids change their behaviors and knowledge from infancy to adolescence. Until now, little was known of the causes that could lead to these changes. New findings unco

Could diet while growing up affect our offspring's vitality? 2013-07-17

By University of Alabama Huntsville

You are what you eat – and so are your offspring. And in the title bout featuring protein versus sugar, protein is the winner. That’s what scientists found while studying the fruit fly (Drosophila melanogaster).

Key factors in understanding differences in rates of birth defects identified 2013-07-17

By University of Leeds

New research highlights important information for health professionals and parents about the factors which may increase the likelihood of a baby being born with a birth defect.

First child born following embryo screening with new genome analysis technique 2013-07-17

By European Society of Human Reproduction and Embryology

The first birth has been achieved following the analysis of embryos using a new genome sequencing technique which promises to revolutionise embryo selection for IVF. The technique has never before been applied in the screening of embryos.

Does marital breakdown have an effect on male offending? 2013-07-17

By Taylor & Francis

Criminologists have long known that men tend to offend less after they marry. But with almost half of all marriages now ending in divorce, what effect does separation have?   

How well can you see with your ears? Device offers new alternative to blind people 2013-07-17

Study of mitochondrial DNA ties ancient remains to living descendants 2013-07-17

By University of Illinois at Urbana-Champaign

Researchers report that they have found a direct genetic link between the remains of Native Americans who lived thousands of years ago and their living descendants. The team used mitochondrial DNA, which children inherit only from their mothers, to track

Smart anticancer 'nanofiber mesh' 2013-07-17

By National Institute for Materials Science

Scientists have developed a new nanofiber mesh which is capable of simultaneously realizing thermotherapy (hyperthermia) and chemotherapy (treatment with anticancer drugs) of tumors. They succeeded in efficiently inducing natural death (apoptosis) of epit

DNA markers in low-IQ autism suggest heredity 2013-07-17

By Brown University

Researchers who compared the DNA of patients with autism and intellectual disability to that of their unaffected siblings found that the affected siblings had significantly more "runs of homozygosity," or blocks of DNA that are the same from bot

Researchers investigate mechanism of Alzheimer's therapy 2013-07-17

By University of Kentucky

Researchers have developed an advance in treatment of Alzheimer's disease. Gammagard™ IVIg is a therapy that has been investigated for treatment of Alzheimer's. Despite small clinical studies that have reported efficacy of the approach, the mech
