New target for drugs to fight the HIV/AIDS virus

Researchers from Rome, Italy, describe a finding in the August 2007 print issue of The FASEB Journal that could lead to new drugs to fight the HIV/AIDS virus, as well as new vaccines to prevent infection.

Mummies provide clues to combat hepatitis B

Mummies that have recently been unearthed in South Korea may provide clues on how to combat hepatitis B, according to Prof. Mark Spigelman of the Kuvin Center for the Study of Infectious and Tropical Diseases at the Hebrew University of Jerusalem.

Discovery of key HIV protein which makes cell membranes bend more easily

Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease.

Simple method to comb genomes

Instead of immutable proprietary software, any species, genetic information resembles open source code that is constantly tweaked and optimized to meet the users specific needs.

Research on proteases and pathological processes

A research group of the UAB Institute of Biotechnology and Biomedicine and the UAB Department of Biochemistry and Molecular Biology, directed by Francesc Xavier Aviles, is the coordinator of a European project aimed at studying proteases with fluorescent molecules that allow their monitoring in healthy and pathological situations.

New method for sequencing both chromosomes of an organism

The statistical method is significant because when researchers announce they have sequenced an organism's genome, they really mean that they have created a mosaic of two chromosomes, said USC computational biologist Lei Li.

Role prefrontal cortex plays in memory

A research with experimental rats carried out by the Institute of Neuroscience of the UAB describes the brain region connected to how our declarative memory functions.

Mathematical model identifies genes which fight viruses

Joint research by Dr. Leonid Brodsky, of the Institute of Evolution of the University of Haifa, and Dr. Milton Taylor, of Indiana University, led to the discovery of a mathematical method which can identify which genes in our bodies conduct the battle against the various viruses that attack us.

A challenge to the ancient origin of SIVagm based on African Green Monkey mitochondrial genomes

Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to new research from The University of Arizona in Tucson.

Emotional memories can be suppressed with practice

A new University of Colorado at Boulder study shows people have the ability to suppress emotional memories with practice, which has implications for those suffering from conditions ranging from post-traumatic stress disorder to depression.

New data about the laws governing embryo development in organisms

Research aimed at understanding the mechanisms underlying embryo development has taken a step forward thanks to collaborative work between biologists specialized in the study of the fruit fly (Drosophila melanogaster) and scientists specialized in the design of mathematical models that simulate the functioning of biological systems.

New evidence of very recent human adaptation

A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa.

New model of early biological evolution

In a study publishing in PLoS Computational Biology, Shakhnovich et al present a new model of early biological evolution , the first that directly relates the fitness of a population of evolving model organisms to the properties of their proteins.

Rapid evolution of defense genes in plants may produce hybrid incompatibility

One of the basic tenets of evolution is speciation in which populations of the same species become so genetically and morphologically variable that they can be classified as two different species.

Neutral genetic drift

Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

Researchers pinpoint brain region responsible for pain's ability to affect cognitive processing

Anybody who's tried to concentrate on work while suffering a headache knows that pain compellingly commands attention,which is how evolution helped ensure survival in a painful world.

RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Study of a Paleolithic diet in early humans

Foods of the kind that were consumed during human evolution may be the best choice to control diabetes type 2. A study from Lund University, Sweden, found markedly improved capacity to handle carbohydrate after eating such foods for three months.
