New Imaging Technique Shows How DNA Is Protected at Chromosomes' Ends

Feb. 11, 2016 — A new imaging technique has allowed researchers to see how DNA loops around a protein that aids in the formation of a special structure in telomeres. Telomeres are essentially caps on the ends of ... read more

Biosensors on Demand

Feb. 11, 2016 — New research leverages a combination of computational protein design, in vitro synthesis and in vivo testing to establish a first-of-its-kind strategy for identifying custom-tailored ... read more

Alternative Proteins Encoded by the Same Gene Have Widely Divergent Functions in Cells

Feb. 11, 2016 — In a first large-scale systematic study, researchers found that most sibling proteins -- known as 'protein isoform' encoded by the same gene -- often play radically different roles within ... read more

Feb. 10, 2016 — DNA is unwound by a type of “pumpjack” mechanism, similar to the way one operates on an oil rig, a team of scientists suggests. This finding is based on new close-up images of the proteins that ... read more

Feb. 10, 2016 — Humans can tolerate the parasites responsible for the sleeping sickness, Chagas disease and leishmaniasis for many years. These parasites belong to the same family of pathogens known as ... read more

Feb. 10, 2016 — Scientists have analyzed more than 500 previously published scientific articles and proposed their own approach to the choice of methods used for the treatment of one of the most common ... read more

Atherosclerosis: A Short Cut to Inflammation

Feb. 10, 2016 — The enzyme Dicer processes RNA transcripts, cutting them into short segments that regulate the synthesis of specific proteins. A research team has shown that Dicer promotes the development of ... read more

Chemical Cages: New Technique Advances Synthetic Biology

Feb. 10, 2016 — A clever means of localizing and confining enzymes and the substrate molecules they bind with has been presented by researchers, speeding up reactions essential for life ... read more

Feb. 9, 2016 — Recently, a new mutation signature found in cancer cells was suspected to have been created by a family of enzymes found in human cells called the APOBEC3 family, report scientists. Mutations are the ... read more

Feb. 9, 2016 — Ecological epigenetics has now been further advanced thanks, to the development of a new research technique. Epigenetic research has grown immensely as a field of research all across the world. In ... read more

'Molecular Movie' Opens Door to New Cancer Treatments

Feb. 9, 2016 — An international team of scientists has produced a 'structural movie' revealing the step-by-step creation of an important naturally occurring chemical in the body that plays a role in some ... read more

Link Between Stress Fracture Injuries, Genes Found

Feb. 9, 2016 — Researchers have successfully identified how certain genes can contribute towards a person's susceptibility to stress fracture injuries. This research provides a platform for further research ... read more

Wound-Healing Intestinal Bacteria: Like Shrubs After a Forest Fire

Feb. 9, 2016 — In injured mouse intestines, specific types of bacteria step forward to promote healing, scientists have found. Potentially, some of these microbes could be exploited as treatments for conditions ... read more

Feb. 9, 2016 — The first robotically driven experimentation system to determine the effects of a large number of drugs on many proteins, reducing the number of necessary experiments by 70 percent, has been created ... read more

Feb. 9, 2016 — A new way of mapping the collection of RNA read-outs that are expressed by a cell's active genes has been devised to shed additional light on the role of RNAs in cells. These 'dark' ... read more

Professors Use Cadaver DNA to Advance Genetics Literacy in Medical Curricula

Feb. 9, 2016 — Cadavers have long been one of the most important resources for anatomy teaching in medical school. Now, they are also at the forefront of cutting-edge genetics teaching, thanks to some innovative ... read more

Researchers See Helpful Protein Causing Cancer

Feb. 9, 2016 — Researchers have determined how a protein that helps cells fight viruses can also cause genetic mutations that lead to cancer. The research shows how the expression of a protein causes mutations to ... read more

Researchers Resolve Longstanding Issue of Components Needed to Regenerate Muscle

Feb. 9, 2016 — New findings clear a path to devise new treatments for muscular injuries and dystrophies, report investigators. The work describes the essential role of a TBP-containing TFIID-protein complex in ... read more

Feb. 9, 2016 — Aneuploid cells—that is to say those with an abnormal number of chromosomes—are found in most human tumors. A study on the fly Drosophila reveals how surviving aneuploid cells favour tumor ... read more

Some Heart Drugs, Antibiotics Show Effective in Fighting Cancer

Feb. 9, 2016 — Drugs that showed promising perspectives in treating cancers have been identified by researchers, according to a recent study. These drugs are normally used to treat other diseases, such as heart ... read more
