Speeding up gene discovery
Since the completion of the Human Genome Project, which identified nearly 20,000 protein-coding genes, scientists have been trying to decipher the roles of those genes. A new approach developed at MIT, the Broad Institute, ...
New sensor tracks zinc in cells, could be exploited for early diagnosis of prostate cancer
Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, ...
Researchers looking to use nanographene oxide to destroy tumors
To treat cancer, is the force strong with nanorobots?
(Phys.org) —Every day, more than 20,000 people around the world succumb to cancer, according to statistics compiled by the World Health Organization. Thousands more continue to suffer through treatment ...
Malignant cells adopt a different pathway for genome duplication
Genomes must be replicated in two copies during cell division. This process occurs at structures called 'replication forks', which are equipped with enzymes and move along the separated DNA strands. In tumour ...
Cylindrical nanoparticles more deadly to breast cancer
(Phys.org) —Cylindrical shaped nanoparticles are seven times more deadly than traditional spherical ones when delivering drugs to breast cancer cells, an international team of researchers has discovered.
Scientists show how cells protect their DNA from catastrophic damage
Researchers at the University of Copenhagen have unveiled a profound biological process that explains how DNA can be damaged during genome replication. In addition, the scientists developed a new analytical tool to measure ...
New technique controls dimensions of gold nanorods while manufacturing on a large scale
North Carolina State University researchers have a developed a technique for efficiently producing nanoscale gold rods in large quantities while simultaneously controlling the dimensions of the nanorods and ...
Big results from tiny particles
Creating and manipulating particles made of just a few atoms is all in a day's work for Dr Richard Tilley.
Researchers synthesize erythropoietin ushering in new era of biotech drugs
Argonne X-rays point way to Nobel Prize, better medicine
You may not know what research earned the 2012 Nobel Prize in Chemistry. But chances are that it will impact your life or that of someone you know.
Two-way traffic enable proteins to get where needed, avoid disease
It turns out that your messenger RNA may catch more than one ride to get where it's going.
