Georgetown professors explore balance of national security and scientific freedom

The U.S. government's request that the journals Science and Nature withhold scientific information related to the genetically modified H5N1 virus because of biosecurity concerns does not violate the First Amendment, say two Georgetown University professors. They caution, however, that a fair, transparent process undertaken by research organizations is preferable to governmental constraints on disseminating scientific information.

Risks of modifying flu strains to become highly transmissible in humans outweigh benefits

In this Journal Sentinel Online opinion piece, Thomas Inglesby, chief executive officer and director of the Center for Biosecurity of UPMC in Baltimore; Anita Cicero, chief operating officer and deputy director of the center; and D.A. Henderson, a distinguished scholar at the center, comment on a recent announcement by scientists that they have genetically modified a strain of H5N1 bird flu that is "capable of spreading through the air between ferrets that were physically separated from each other," indicating "it would be readily transmissible by air between humans."

Researchers identify critical cellular, molecular events that lead to esophageal adenocarcinoma

Researchers at Columbia University Medical Center (CUMC) have identified the critical early cellular and molecular events that give rise to a type of esophageal cancer called esophageal adenocarcinoma, the fastest-rising solid tumor in the United States.

Scientists identify pathway that activates hepsin on the surface of breast tumor cells

Scientists from the University of Helsinki and from UCSF have exposed a cell pathway that breast tumor cells use to destruct local tissue neighborhood. Cancer cells may use this pathway to free themselves from mammary epithelial tissue architecture, to spread to surrounding tissues. The cell pathway, the researchers found, is a biochemical chain of events leading to activation of a protein-cleaving enzyme on the surface of the tumor cells.

Researchers develop simple process for synthesis of artemisinin

The most effective anti-malaria drug can now be produced inexpensively and in large quantities. This means that it will be possible to provide medication for the 225 million malaria patients in developing countries at an affordable price. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam and the Freie Universit-t Berlin have developed a very simple process for the synthesis of artemisinin, the active ingredient that pharmaceutical companies could only obtain from plants up to now.

AICAR might protect against heat stress in MH-susceptible individuals

Malignant hyperthermia (MH) is a life-threatening genetic muscle disorder, most commonly triggered in those at risk by certain types of drugs used during anesthesia. Heat stroke, on the other hand, most commonly occurs in individuals in response to physical exertion in hot/humid environments. While their common triggers may differ, the signs associated with MH and heat stroke are remarkably similar - uncontrolled muscle contractions, dangerous increases in body temperature, and muscle breakdown leading to the release of toxins in the blood which may cause cardiac arrhythmias and death. Immediate treatment for these conditions is crucial.

Researchers identify human receptor that can taste fat

Why do we like fatty foods so much? We can blame our taste buds. Our tongues apparently recognize and have an affinity for fat, according to researchers at Washington University School of Medicine in St. Louis. They have found that variations in a gene can make people more or less sensitive to the taste of fat.

Scientists discover how sense of touch is wired in skin and nervous system

Neuroscientists at the Johns Hopkins University School of Medicine have discovered how the sense of touch is wired in the skin and nervous system. The new findings, published Dec. 22 in Cell, open new doors for understanding how the brain collects and processes information from hairy skin.

Special issue on self-determining environmental justice for native America

How best to ensure environmental justice for Native Americans in terms of policy, governance, and activism on tribal lands? The broad range of issues, challenges, and possibilities are explored in an insightful and thought-provoking special issue of Environmental Justice entitled "Environmental Justice in Native America." Environmental Justice is a peer-reviewed journal published by Mary Ann Liebert, Inc.

Scientists discover N-cadherin as promising therapeutic target for pancreatic cancer

Often, and without much warning, pancreatic cancer cells slip through the endothelial cells, head into the blood and out to other parts of the body to metastasize, making it one of the deadliest and hardest to treat cancers today.

SIRT1 gene appears to delay onset of HD in mouse model

Working with genetically engineered mice, Johns Hopkins researchers have discovered that a gene (SIRT1) linked to slowing the aging process in cells also appears to dramatically delay the onset of Huntington's disease (HD) and slow the progression of the relentless neurodegenerative disorder.
