Advances in age-related macular degeneration treatment

A new study of age-related macular degeneration (AMD), a disease that affects more than nine million Americans, will pave the way for the biopharmaceutical industry to develop better treatments and cures, according to the Foundation Fighting Blindness, which partially funded the research.

Genetic roots of obesity

A discovery by Queen's biologists and their students sheds new light on the genetic roots of obesity a condition that is increasing dramatically in North America and has been linked to heart disease, diabetes and some forms of cancer.

Quality control mechanism tags defective sperm cells inside the body

Defective sperm cells do not pass through the body unnoticed. A new University of Missouri study provides evidence that the body recognizes and tags defective sperm cells while they undergo maturation in the epididymis, a sperm storage gland attached to the testis.

DNA sensors found to be an effective artificial nose

In designing artificial noses modeled after biological olfaction, the challenge has been to generate a similarly large sensor repertoire with the requisite combinatorial complexity to detect odors in the real world.

Scientists use nanoscale polymer films to control drug delivery

Using nanotechnology, scientists from UCLA and Northwestern University have developed a localized and controlled drug delivery method that is invisible to the immune system, a discovery that could provide newer and more effective treatments for cancer and other diseases.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.

Flame retardant chemicals found in body fat of Tasmanian Devil

A wild carnivorous marsupial which only exists on the Australian island state of Tasmania has been found to have high levels of flame retardant chemicals.

Studies highlight MRSA evolution and resilience

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain USA300 of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.

Contact lenses with imprinted electronic circuit and lights

Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs.

Gene markers located for hereditary prostate cancer

Researchers at the Johns Hopkins Brady Urological Institute, Wake Forest University and the Karolinska Institute in Sweden have identified an array of gene markers for hereditary prostate cancer that, along with family history for the disease, appear to raise risk to more than nine times that of men without such markers.

Analysis shows adverse health consequences from overdue EPA emissions standards for diesel trains and ships

A new technical analysis shows that even a one year delay by the U.S. Environmental Protection Agency in implementing overdue emission standards for diesel trains and ships will allow serious health effects to go unaddressed over the course of EPA's program.

Researchers find new way to block destructive rush of immune cells

Researchers have found a way to selectively block the ability of white blood cells to "crawl" toward the sites of injury and infection when such mobility drives disease, according to a study published today in The Journal of Experimental Medicine.

U.S. Food and Drug Administration approves new genetic breast cancer test

The U.S. Food and Drug Administration has approved a test that helps in assessing the risk of tumor recurrence and long-term survival for patients with relatively high-risk breast cancer. The TOP2A FISH pharmDx is the first approved device to test for the TOP2A (topoisomerase 2 alpha) gene in cancer patients.
