Spliceosome crucial for processing non-coding RNA

The discovery in 1977 that the coding regions of a gene could appear in separate segments along the DNA won the 1993 Nobel Prize in Physiology or Medicine for Richard J. Roberts and Phillip A. Sharp. The active segments of a gene were termed exons, separated from each other within the gene by inactive introns.

First time a protein serving as a template for DNA synthesis seen

Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.

Equine flu virus jumps to dogs

A Cornell University virologist has isolated a highly contagious equine flu virus that is spreading a sometimes-fatal respiratory flu among dogs, and is responsible for a major dog-flu outbreak in New York state. There is no evidence that the virus could infect people.

Changes to prenatal genetic testing could mean more babies born with abnornalities

A study in the UK suggests that a proposed change to the type of prenatal genetic testing offered to couples in the UK, could possibly result in certain chromosome abnormalities being missed.

Birth abnormality rates could increase if proposed changes to prenatal testing go ahead

A proposed change to the type of prenatal genetic testing offered to couples in the UK could result in certain chromosome abnormalities being missed, suggests a study published online today (Thursday June 30, 2005) by The Lancet.

Inactive gene may explain higher incidence of prostate cancer in African-Americans compared to Caucasians

Among African-Americans with prostate cancer, a tumor-suppressing gene called GSTP1 is inactivated at a rate 3.5 times higher than among Caucasians, according to a study conducted at the San Francisco VA Medical Center (SFVAMC).

Tonsil swabbing is terrible - it makes people gag

Mayo Clinic ear, nose and throat surgeons hoped to find a more user-friendly test for strep throat than swabbing the tonsils directly, but instead discovered that the swab has to touch the tonsils to accurately detect the infection.

A simple spit test could predict cancers

In future scientists say, a test as simple as spitting into a collection tube or cup might be a screening test for breast cancer and the early detection of other tumours.

Alarming trends in sexually transmitted diseases (STDs) among America's young people

A study by ASHA, sponsored by Roche Diagnostics of Indianapolis, Indiana is being released in conjunction with April's STD Awareness Month and demonstrates that the incident rate of STDS in youth (ages 15-24) have increased dramatically in recent years.

CDC experts sent to Angola to help with Marburg epidemic

In an effort to control the Marburg virus outbreak in Angola, Health officials from the Centers for Disease Control and Prevention in Atlanta will assist the World Health Organization by going to Angola to help with outbreak investigation, infection control and laboratory diagnosis of the disease.

DNA sequencing made portable and faster by "colour-blind" technology

Researchers at Baylor College of Medicine (BCM) and Rice University have developed a"colour-blind" method of fluorescence detection which could open new doors that would take DNA sequencing to the patient's bedside, the doctor's office and even the scene of a crime or a battlefield.

Test that will prevent the needless loss of the thyroid gland in people with the noncancerous condition

New research suggests that physicians can distinguish between a type of thyroid cancer and an identical-looking, non-cancerous thyroid condition by simply determining the activity of three genes.

DNA weak links may provide clues to cancer biology

The chromosomes of mammals, including humans, contain regions that are particularly prone to breaking under conditions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them.

Finding may open new horizons for understanding the initiation of chemically induced cancers

A team from the chemistry and biology departments of New York University, in collaboration with Memorial Sloan Kettering Cancer Center (MSKCC), has uncovered a conformational switch - a change in shape in a carcinogen-damaged DNA site - in tumor suppressor genes altered by a known cancer-causing chemical found in cigarette smoke.

New findings on the regulation of cellular growth

A greatly increased synthesis of new proteins is one of the first and most important events that occur in both normal and tumour cells upon growth stimulation.

Ebola virus outbreaks linked to infected wild animal carcasses

All recent Ebola virus outbreaks in humans in forests between Gabon and the Republic of Congo were the result of handling infected wild animal carcasses, according to a study by the Wildlife Conservation Society (WCS) and its regional partners

New technique can greatly facilitate the development of vaccines against infectious diseases such as smallpox, malaria and tuberculosis

Because the new technique can synthesize a large number of proteins very quickly, it has potential to accelerate vaccine development, particularly crucial in the fight against bioterrorism.
