While your DNA is unique, it also tells the tale of your family line. It carries the genetic history of your ancestors down through the generations. Now, says a Tel Aviv University researcher, it's also possible to use it as a map to your family's past.
Experts agree that, more than ever before, modern wars will be fought in the cyber zone, targeting an enemy's communications technology to cause untold damage. Now a Tel Aviv University researcher is suggesting that the same tactics should be employed in the battle against one of the body's deadliest enemies - cancer.
Even after being frozen for 18 years, human embryos can be thawed, grown in the laboratory, and successfully induced to produce human embryonic stem cells, which represent a valuable resource for drug screening and medical research.
An international team of researchers led by computer scientist Pavel Pevzner, from the University of California, San Diego, have developed a new algorithm to sequence organisms' genomes from a single cell faster and more accurately.
Bioengineers at the University of California, San Diego have developed a method of modeling, simultaneously, an organism's metabolism and its underlying gene expression. In the emerging field of systems biology, scientists model cellular behavior in order to understand how processes such as metabolism and gene expression relate to one another and bring about certain characteristics in the larger organism.
Georgia Tech researchers are focusing on ways to fight cancer by attacking defective genes before they are able to make proteins. John McDonald is studying micro RNAs (miRNAs), a class of small RNAs that interact with messenger RNAs (mRNAs) that have been linked to a number of diseases, including cancer. McDonald's lab placed two different miRNAs (MiR-7 and MiR-128) into ovarian cancer cells and watched how they affected the gene system.
Manuals for designing a synthetic promoter using the DNA CAD environment for Challenge A, as well as pointers for designing DNA sequences to introduce plant functions for Challenge B are now available from the GenoCon website.
A team of researchers from the University of Copenhagen have developed a method to hinder unwanted toxins from entering the edible parts of plants such as the oilseed rape, which will make it suitable for animal feed.
The microbial community or microbiome that inhabits the rhizosphere and endosphere - the niches immediately surrounding and inside a plant's root?facilitates the shuttling of nutrients and information into and out of the roots within the soil matrix. These underground microbial activities have not received as much attention as the effort to characterize the role of the microbial populations inside and on the surfaces of humans, but this is now changing owing to a recent publication.
