Chemists create 'Superbowl' molecule; May lead to better health

...hich acknowledged this and recognized their larger size and shape," says Sherburn. "'Superbowl' was perfect since it conjures up ?for me at least ?the image of a sports stadium, which the molecules are similar to in shape." Appropriately, the researcher is also a football fan and watches the Super Bowl e...

Quantum Dots Research Leads to New Knowledge about Protein Binding in Plants

...anconventional fluorescent markers and their small size make them idealfor biological imaging. The researchers then added the molecules togerminated lily pollen grains and examined them under a confocalmicroscope.This is the very first time that Quantum Dots have been utilized forlive imaging in plant sys...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...p? The researchers found no difference in pancreas size or numbers of pancreatic beta cells, which produce insulin. But cultures of the beta cells revealed the answer: the undernourished mice had an abnormal way of responding to glucose. "They were somehow 'programmed' to secrete a limited amount of insu...

Piecing together their ancient family trees, he has discovered that the Antarctic population of minke whales is now the longest surviving whale population on earth. It was also once the largest—many times larger than other estima...

Color-blind method opens new doors in DNA sequencing

...ion (PCR) steps, reduce its length to a manageable size of thousands of nucleotides. Using natural replicating enzymes, the DNA is tagged with four fluorescent dyes, each corresponding to a particular nucleotide. This tagging process, called Sanger sequencing, results in smaller DNA fragments, which are t...

Mouse brain tumors mimic those in human genetic disorder
