Texas A&M Researchers Examine How Viruses Destroy Bacteria <http://www.eurekalert.org/pub_releases/2009-11/tau-tar111809.php>
Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria. Texas A&M University researchers are exploring how hungry viruses, armed with transformer-like weapons, attack bacteria, which may aid in the treatment of bacterial infections.

New on-off 'switch' triggers and reverses paralysis in animals with a beam of light <http://www.eurekalert.org/pub_releases/2009-11/acs-no111809.php>
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the animals become unparalyzed and wake up.

Cancers' sweet tooth may be weakness <http://shared.web.emory.edu/whsc/news/releases/2009/11/cancers-sweet-tooth-may-be-weakness.html>
Cancer cells tend to take up more glucose than healthy cells and metabolize it in a process called glycolysis. An enzyme called PKM2 that governs cancer cells' preference for glucose may be a valuable anti-cancer drug target.

Immediate, aggressive spending on HIV/AIDS could end epidemic <http://www.eurekalert.org/pub_releases/2009-11/bc-ias111609.php>
Money available to treat HIV/AIDS is sufficient to end the epidemic globally, but only if we act immediately to control the spread of the disease, according to research published in BMC Public Health. This approach defies conventional thinking, which recommends gradual spending over 15-20 years. The study was based on a mathematical model developed by mathematicians and biologists, who recently earned acclaim for a study on how best to handle a planetary invasion by zombies.

Scientists guide immune cells with light and microparticles <http://www.opa.yale.edu/news/article.aspx?id=7082>
A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. They used holographic optical tweezers to guide "artificial bacteria" -- microparticles that mimic bacteria by giving off a chemical "scent," stimulating immune cells to respond. By controlling the chemical patterns produced, they were able to study how immune cells respond to and interact with these chemical signals.

Tiny particles can deliver antioxidant enzyme to injured heart cells <http://www.eurekalert.org/pub_releases/2009-11/eu-tpc111309.php>
Researchers have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart. Injecting the enzyme-containing particles into rats' hearts after a simulated heart attack reduced the number of dying cells and resulted in improved heart function days later.

Vaccine To Treat Nicotine Addiction Steps Closer To Market As Companies Agree Option Deal <http://www.medicalnewstoday.com/articles/171318.php>
An experimental vaccine called NicVAX, designed to treat nicotine addiction that works by stopping the drug from reaching the brain, moved a step closer to the market when the vaccine developer Nabi Biopharmaceuticals (Nabi), based in Rockville, Maryland, US agreed an option and licensing deal with GlaxoSmithKline Biologicals SA (GSK), based in Brussels, Belgium.
The deal also covers the development of a second generation nicotine vaccine, so that even if GSK does not go ahead with its option to sell the current version of NicVAX, they get the right to develop the next generation themselves using Nabi's research and development knowledge.

Technology advances are making life better for the elderly and those with Alzheimer's disease <http://www.medicalnewstoday.com/articles/159442.php> by allowing the older to stay in their homes and giving the ill a way to interact with society again. Kaiser Health News <http://www.kaiserhealthnews.org/Stories/2009/November/17/New-technology.aspx> , in collaboration with The Washington Post <http://www.washingtonpost.com/wp-dyn/content/article/2009/11/16/AR2009111602900.html?hpid%3Dartslot&sub=AR> , reports on "high-tech but simple devices" that are giving older people a better chance at independence later in life as pilot projects in homes and retirement communities see if these approaches can lead to improved at-home patient monitoring. "The goal is to help control problems before they escalate and cut back on the need for costly long-term care and hospital admissions - especially repeat hospital visits for chronic conditions. … The hope is that by closely monitoring patients at home, some of these (major health) events can be avoided or managed better" (Olson, 11/17).

The Use Of Stem Cells In Regenerative Medicine May Be Detrimental For Health <http://www.medicalnewstoday.com/articles/170894.php>
The use of stem cells <http://www.medicalnewstoday.com/info/stem_cell/whatarestemcells.php> in regenerative medicine is not always beneficial for human health, it may even be harmful according to a work done by the University of Granada and University of León. Scientists have demonstrated that transplantation of human mononuclear cells isolated from umbilical cord blood exerted a deleterious effect in rats with liver cirrhosis. Researchers aimed to investigate whether the mononuclear cell fraction of human cord blood (HUCBM cells), which contains stem cells, might be useful in hepatic regenerative medicine. Both histological and biochemical findings obtained in this research suggest that cell transplantation did not improve the health of sick animals but it induced a hepatorenal syndrome instead.
