MNT: Our Genes May Be The Reason Why Our Immune Systems Decline With Age

18.7.2012   |   News of Science

Important insights that explain why our ability to ward off infection declines with age are published in a new research report in the July 2012 issue of the Genetics Society of America's journal, GENETICS.


Wheat grain yield on saline soils is improved by an ancestral Na⁺ transporter gene.

12.7.2012   |   News of Science

The ability of wheat to maintain a low sodium concentration ([Na(+)]) in leaves correlates with improved growth under saline conditions. This trait, termed Na(+) exclusion, contributes to the greater salt tolerance of bread wheat relative to durum wheat. To improve the salt tolerance of durum wheat, we explored natural diversity in shoot Na(+)...


Totally rad: Scientists create rewritable digital data storage in DNA

9.7.2012   |   News of Science

( Scientists from Stanford's Department of Bioengineering have devised a method for repeatedly encoding, storing and erasing digital data within the DNA of living cells.


A novel PCR-based method for high throughput prokaryotic expression of antimicrobial peptide genes

28.6.2012   |   News of Science

To facilitate the screening of large quantities of new antimicrobial peptides (AMPs), we describe a cost-effective method for high throughput prokaryotic expression of AMPs. EDDIE, an autoproteolytic mutant of the N-terminal autoprotease, Npro, from classical swine fever virus, was selected as a fusion protein partner. The expression system was...


MNT: Genes May Influence Quitting Success

A person's genetic make up may influence their chances of successfully giving up smoking, according to an NIH-funded study published in the 30 May online issue of the American Journal of Psychiatry


PhysOrg: Amoeba offers key clue to photosynthetic evolution

18.6.2012   |   News of Science

( -- The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy. When light isn't available, energy is generated by breaking down carbohydrates and sugars, just as it is in animal and some bacterial cells. Two cellular organelles are responsible for these two...

MNT: Discovery Of New Genetic Mechanism Of Immune Deficiency

7.6.2012   |   News of Science

Researchers at National Jewish Health have discovered a novel genetic mechanism of immune deficiency. Magdalena M. Gorska, MD, PhD, and Rafeul Alam, MD, PhD, identified a mutation in Unc119 that causes immunodeficiency known as idiopathic CD4 lymphopenia. Unc119 is a signaling protein that activates and induces T cell proliferation. The mutation...


PhysOrg: Meteorites reveal another way to make life's components

4.6.2012   |   News of Science

( Creating some of life's building blocks in space may be a bit like making a sandwich – you can make them cold or hot, according to new NASA research. This evidence that there is more than one way to make crucial components of life increases the likelihood that life emerged elsewhere in the Universe, according to the research team,...


MNT: Critical Genes Mutated In Stomach Cancer Identified

28.5.2012   |   News of Science

An international team of scientists, led by researchers from the Duke-NUS Graduate Medical School (Duke-NUS) in Singapore and National Cancer Centre of Singapore, has identified hundreds of novel genes that are mutated in stomach cancer, the second-most lethal cancer worldwide.
