Polyphenols in wine may help prevent cavities

A class of chemicals in red wine grapes may significantly reduce the ability of bacteria to cause cavities, according to a study published recently in the Journal of Agricultural and Food Chemistry.

Scientists find missing evolutionary link using tiny fungus crystal

The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.

Model developed that predicts molecular response of living cells to genetic or environmental change

Scientists at the Institute for Systems Biology (ISB), in collaboration with researchers from New York University (NYU), have developed a model which rapidly characterizes and accurately predicts the molecular-level, mechanistic response of a free-living cell to genetic and environmental changes.

Copy number variation may stem from replication misstep

Genome rearrangements, resulting in variations in the numbers of copies of genes, occur when the cellular process that copies DNA during cell division stalls and then switches to a different genetic "template," said researchers at Baylor College of Medicine in Houston in a report that appears today in the journal Cell.

The smell of sound - researchers look at phenomenon synaesthesia

The research field has grown from grapheme-colour synaesthesia to include other forms of synaesthesia in which flavours are evoked by music or words (lexical-gustatory synaesthesia), space structures by time units, colours by music, etc.

Australian researchers tackle antibiotic resistance

The development of antibiotic resistant strains of bacteria that are problematic and expensive to treat is a major healthcare problem around the world. The "selective pressure" of antibiotic usage inevitably results in the emergence and proliferation of resistant bacteria.

Researchers spearhead key genome initiative

The complete collection of genes - the genome - of a moss has been sequenced, providing scientists an important evolutionary link between single-celled algae and flowering plants.

Evolution with a restricted number of genes

The development of higher forms of life would appear to have been influenced by RNA polymerase II.

How cell differentiation patterns suppress somatic evolution

Natural selection can occur at the cellular level, where it is detrimental to health.

Chimpanzees don't go through menopause

Researchers have found no evidence that chimpanzees in the wild undergo menopause in the way that women do, according to a new report published online on December 13th in Current Biology, a Cell Press publication.

Same genetic machinery generates skin color evolution in fish and humans

When humans began to migrate out of Africa about 100,000 years ago, their skin color gradually changed to adapt to their new environments.

Adapting to pregnancy played key role in human evolution

The human spine evolved differently in males and females in order to alleviate back pressure from the weight of carrying a baby, according to research spearheaded at The University of Texas at Austin.

Losses of long-established genes contribute to human evolution

While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage.

Female lower back has evolved to accommodate the weight of pregnancy

When a pregnant woman leans back, and shifts her weight to stand more comfortably, she is performing a motion that for millions of years has helped to compensate for the strain and weight of childbearing on the body.

Extracts from fungi show potential as prostate cancer treatment

A new development in the fight against cancer: Recent research at the University of Haifa found that molecules found in common fungus Ganoderma lucidum aid in suppressing some of the mechanisms involved in the progression of prostate cancer.

When a female is attracted to a male some of her genes turn on and off

When a female is attracted to a male, entire suites of genes in her brain turn on and off, show biologists from The University of Texas at Austin studying swordtail fish.

Human evolution in genetic fast lane

Countering a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a new study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts.
