He catalogues the references and keeps track of them all. Gribble emphasizes that many of these natural organohalogens have pot...

Rutgers chemist uses NMR to elucidate protein-DNA interaction

...vant DNA sequence, but the interaction is weak. It searches for the correct sequence by sliding along the DNA until it can bind with a specific DNA sequence and form a complex," Kalodimos explained. "This helps us begin to complete the story of how proteins and DNA find each other in a very fast and accurate ...

Secret behind hard exoskeletons, spreading wings revealed

...-doctoral researcher in Honegger's laboratory, ran searches on the genome of the fruit fly and found that three of the four sequences matched the sequence of the fruit fly gene CG13419. She subsequently compared the sequence to known genomes for other insects and also found matches, leading the team to determ...

Spanish scientists develop powerful tool for exploration and integration of biological information

The iHOP system shows that distant medical and biological concepts can ...

Ribozyme package effective against hepatitis B virus

...ine researchers have developed a tiny package that searches for and destroys up to 80 percent of hepatitis B virus in the livers of mice. "This marks one of the few successful in vivo, or in-animal, models of an effective therapy to reduce the production of hepatitis B virus," said Gary Clawson, M.D., Ph.D.,...

Leslie Wilson, a molecular cell biologist, specializes in understanding the role of the cytoskeleton in normal cells as well as in cancerous cells and neurodegenerative diseases. "If we are suc...

Researchers identify new cause of genomic instability

...ation would not have been readily detected in most searches for genes that suppress tumors in humans. Indeed, Bassing discovered that tumors in these mice still had a functioning H2AX gene. "A major question is why haploinsufficiency of the H2AX protein can cause genomic instability and cancer," said Alt. "...

Can female adult obesity be stopped at birth?

...s things fixed instantly. Among the most prominent searches for the "quick fix" is weight loss. Could our own physiology rather than a purchased liquid concoction one day be the key to female obesity? Perhaps. Background The body's energy homeostasis is maintained by a highly complex and integrated neuro...

Making sense of the genome

...sfully increased the signal to noise ratio of such searches by using a powerful combination of two methods. Firstly, the regulatory sequences are scanned for binding sites, but only for those that are known to be biologically active. For this comparison, Wasserman's team compiled a searchable database of 10...

Researchers find viral protein that mimics its way into cells

More recently, searches for genetic underpinnings of alcoholism, intelligence, and personality traits have sparked controversy, over the scientific strength of the data and the studies' perceived implications e.g., that some individuals may be less accountable for their ac...

Families with severe form of bipolar disorder help scientists narrow the search for disease genes

After years of frustrating searches for genes that contribute to mental illness, researchers at Johns Hopkins studying families with a severe form of manic depressive illness, called psychotic bipolar disorder, may be one step closer to finding the genetic underpinnings of both bipolar...
