Molecular Biology News and Research

RSS

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

UIC receives $20 million NCI grant to research blood disorders

Researchers decode the instructions that tell cells how to become blood

Blood cells have limited lifespans, which means that they must be continually replaced by calling up reserves, and turning these into the blood cell types needed by the body.

Mature muscle fibers can revert to become cancerous

Mature muscle fibers, rather than their less-developed neighbors, are the tissues that turn malignant in a soft-tissue cancer that strikes children and teens, researchers at UT Southwestern Medical Center and Children's Medical Center Dallas have found.

Hopkins develops online tool to aid research on certain "orphan diseases"

Many people are afflicted with rare illnesses of unknown cause, and finding a common link to such under-studied or "orphaned" diseases as Bardet-Biedl, Alstrom and Meckel-Gruber syndromes can significantly advance the search for causes and treatment.

New methods for screening nanoparticles and interaction with human cells

Scientists have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses.

DNA of human embryonic stem cells is chemically modified in a characteristic, predictable pattern

Embryonic stem cells are derived from embryos that are undergoing a period of intense cellular activity, including the chemical addition of methyl groups to specific DNA sequences in a process known as DNA methylation.

Gifted kids reject schools' diet - but choose healthy eating

A new survey of over 700 gifted young people by the University of Warwick shows that they consider themselves bright enough to take responsibility for their food choices and don't think that schools should be allowed to dictate their diet.

Listeriosis and pregnancy

For years, doctors have puzzled over why pregnant women are 20 times more likely than others to be infected by the bacterium Listeria monocytogenes. Researchers at the University of California, Berkeley, now think they have the answer, and it isn't pretty.
