Patent issued for generating genetically evolved mammalian cells through the regulation of mismatch repair

Morphotek announced today the issuance of United States Patent 6,825,038 covering the regulation of mismatch repair (MMR), a powerful process for generating functional diversity in mammalian cells, to yield sibs exhibiting desirable phenotypes for target discovery, drug screening and/or product development.

Powerful women at a disadvantage in the marriage market because men may prefer to marry less accomplished women

Men are more likely to want to marry women who are their assistants at work rather than their colleagues or bosses, a University of Michigan study finds.

Discovery of key immune system molecules that helps determine how effectively a person resists HIV infection

A team of researchers based partly in South Africa has identified a key set of immune system molecules that helps determine how effectively a person resists infection with human immunodeficiency virus (HIV).

Gauging the risk from prolonged low-level radiation

Everyone knows that high doses of radiation are dangerous, but the effects of long-term exposure to low-level radiation is poorly understood. RISC-RAD, a new European Union backed research project, seeks to identify our tolerance threshold so as to optimise protective measures.

New clues in understanding why group A streptococci (GAS) has a range of bacterial afflictions in humans

Researchers have unlocked new clues in understanding why group A streptococci (GAS) has a range of bacterial afflictions in humans. One of the keys to this species of bacteria is its production of streptokinase (SK), an enzyme that activates plasminogen, the blood clot-dissolving protein in humans.

MRI reveals similarities between the human and chimpanzee brain

New MRI-based studies present more evidence that the brains of chimpanzees are human-like in terms of the relationships among brain asymmetry, handedness and language, according to research undertaken at the Yerkes National Primate Research Center in Atlanta.

Human endogenous retroviruses (HERVs)

Human endogenous retroviruses (HERVs) have been the subject of a great deal of investigation in recent years. It has been established that HERVs cause some genetic diseases and there is strong circumstantial evidence for a link to some types of cancer and autoimmune diseases, but what else do we need to know about these unique organisms?

Fossil record of the human immune system reveals antibodies that block cancer metastasis

A team of researchers at The Scripps Research Institute has reconstructed the "fossil record" of the immune systems of a group of human cancer patients to investigate if they had ever produced antibodies against their disease.

Women now making up nearly half of the 37.2 million adults (aged 15-49) living with HIV worldwide

A new report released today shows that the number of women living with HIV has risen in each region of the world over the past two years, with the steepest increases in East Asia, followed by Eastern Europe and Central Asia. In East Asia, there was a 56% increase over the past two years, followed by Eastern Europe and Central Asia with 48%.

Cells linked to asthma and eczema also help cure deadly illness in mice

Mast cells are immune cells known mostly for their unwanted effects: they cause the wheezing of asthma, the itching of eczema, the sneezing and runny nose of hay fever and, in extreme cases, the life-threatening shock of anaphylaxis.

Combining radiation therapy with surgery and chemotherapy helps patients with rare forms of thyroid cancer live longer

Combining radiation therapy with surgery and chemotherapy helps patients with rare forms of thyroid cancer live longer, according to a study published in the November 15, 2004, issue of the International Journal of Radiation Oncology~Biology~Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

Sex genes of infectious fungus closely resemble human Y chromosome

Fungi and animals, including humans, have a lot in common when it comes to the arrangement of genes that determine their sex, according to new work by Howard Hughes Medical Institute geneticists at the Duke University Medical Center.

Researchers have developed a new algorithm that can lead to more accurate detection of cancer genes

Researchers at New York University's Courant Institute of Mathematical Sciences have developed a new algorithm that can lead to more accurate detection of cancer genes than previous versions.

Stone tools of Indonesian "hobbit" studied

A Southern Cross University researcher has begun the painstaking task of analysing hundreds of stone tools believed to have been used by the “hobbits” – a new species of miniature humans found on the Indonesian island of Flores.

Sexual competition among males is evident at the molecular level, as well as at behavioral and physiological levels

In what could be termed a truly seminal discovery, researchers have shown that when females are more promiscuous, males have to work harder -- at the genetic level, that is. More specifically, they determined that a protein controlling semen viscosity evolves more rapidly in primate species with promiscuous females than in monogamous species.

Crystal structure of protein AIRs kinase uncovered

Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.

Scientists have found a fossil that explains the history of the nose

Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve?

Researchers provide concrete evidence about how the human eye evolved

When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye, an "organ of extreme perfection and complication" evolved through spontaneous mutation and natural selection.

Interaction of nervous system proteins help researchers better understand age-related memory and hearing loss

In a finding that may one day help researchers better understand age-related memory and hearing loss, scientists have shown that two key nervous system proteins interact in a manner that helps regulate the transmission of signals in the nervous system.
