Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

New Ebola variant identified in Guinea

Performed in less than a month, sequencing of the complete genome and subsequent phylogenetic analysis show that the virus present in Guinea forms a clade (variant) that is distinct from strains previously identified in the Democratic Republic of Congo and in Gabon. Epidemiological investigations also linked the laboratory confirmed cases with the initial deaths recorded during the December 2013 outbreak.

Exposure to microgravity can simulate aging for immune cells

Telling someone to "act your age" is another way of asking him or her to behave better. Age, however, does not always bring improvements.

Investigators use computer-assisted approach to identify and rank new clock genes

Over the last few decades researchers have characterized a set of clock genes that drive daily rhythms of physiology and behavior in all types of species, from flies to humans.

Study reveals how human genome is protected from inadvertent import of viral RNA into cell

Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell.

Pediatric viral respiratory tract infection often complicated by bacterial sinusitis

Nearly 1 in 10 cases of viral upper respiratory tract infections in infants and young children is complicated by acute bacterial sinusitis, often in conjunction with acute otitis media, a longitudinal cohort study has found.

New computational method speeds up estimates of gene activity from RNA-seq data

With gene expression analysis growing in importance for both basic researchers and medical practitioners, researchers at Carnegie Mellon University and the University of Maryland have developed a new computational method that dramatically speeds up estimates of gene activity from RNA sequencing (RNA-seq) data.

New device uses space-tested concept of capillary flow to diagnose infectious diseases

A new medical-testing device is being prepped to enter the battle against infectious disease. This instrument could improve diagnosis of certain diseases in remote areas, thanks in part to knowledge gained from a series of investigations aboard the International Space Station on the behavior of liquids. The device uses the space-tested concept of capillary flow to diagnose infectious diseases such as HIV/AIDS and tuberculosis.

U.Va. researchers named recipients of 2013 Hartwell Individual Biomedical Research Awards

University of Virginia neurologist Dr. Erin Pennock Foff, biologist Sarah Kucenas and biomedical engineer Shayn Peirce-Cotter have been named recipients of 2013 Hartwell Individual Biomedical Research Awards to benefit children of the United States. Each scientist will receive $100,000 in direct annual research support from The Hartwell Foundation for three years.

Study sheds light on how extra chromosome 21 upsets equilibrium of entire genome in Down syndrome

Occurring in about one per eight hundred births, Down syndrome - or trisomy 21 - is the most frequent genetic cause of intellectual disability. It results from a chromosomal abnormality where cells of affected individuals contain a third copy of chromosome 21 (1% of the human genome).

New research may help scientists develop treatments or vaccines for Dengue fever

Two recent papers by a University of Colorado School of Medicine researcher and colleagues may help scientists develop treatments or vaccines for Dengue fever, West Nile virus, Yellow fever, Japanese encephalitis and other disease-causing flaviviruses.

Professor from INRS receives NIH grant to explore biomedical potential in field of oncology

Professor Nicolas Doucet of the Centre INRS-Institut Armand-Frappier has just received a research grant from the National Institutes of Health (NIH) in the amount of nearly US$600,000. The 5-year grant is to pursue cutting-edge research in the workings of tiny proteins called RNases and to explore their biomedical potential in the field of oncology as well as in inflammation and asthma.

Researchers identify new Chinese herbal medicine that inhibits hepatitis C virus activity

Data from a late-breaking abstract presented at the International Liver CongressTM 2014 identifies a new compound, SBEL1, that has the ability to inhibit hepatitis C virus (HCV) activity in cells at several points in the virus' lifecycle.

New technique of single-cell genomic analysis to reverse tissue engineering

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body.

Tumor-suppressing protein acts as dimmer switch to dial down gene expression

A tumor-suppressing protein acts as a dimmer switch to dial down gene expression. It does this by reading a chemical message attached to another protein that's tightly intertwined with DNA, a team led by scientists at The University of Texas MD Anderson Cancer Center reported at the AACR Annual Meeting 2014.

Scientists solve a decades-long mystery of cell biology

A team led by scientists at The Scripps Research Institute has identified a long-sought protein that facilitates one of the most basic functions of cells: regulating their volume to keep from swelling excessively.
