Morse code is a simple, effective and clear method of communication and now scientists believe that cells in our body may also be using patterns of signals to switch genes on and off. The discovery may have major implications for the pharmaceutical industry as the signalling molecules that are targeted by drugs may have more than one purpose. The number of ‘dots and dashes’ being used by each signal could have different purposes, all of which could be modified by a drug.

A comprehensive response to HIV could prevent 10 million AIDS deaths in Africa by 2020
One of the most urgent problems in HIV/AIDS policy is in deciding how best to allocate resources toward preventing new infections or treating infected individuals.
An analysis by Joshua Salomon and colleagues in the premier open-access journal PLoS Medicine, published online January 11, 2005, suggests that an exclusive focus on one or the other of these alternatives will yield minima

COPD (chronic obstructive pulmonary disease) is one of the most common fatal diseases worldwide. In Germany alone, there are about 3-5 million patients affected. COPD includes both chronic obstructive bronchitis and emphysema. Both represent irreversible changes of the central and lower respiratory tract which are accompanied by coughing, mucus production and difficulty in breathing.
The increased production of mucus is induced by the immigration of neutrophilic granulocytes a
Groundbreaking research project may help boost vaccine development
In an innovative project with implications for malaria vaccine development, scientists have used genomics, proteomics and gene expression studies to trace how malaria parasites evolve on a molecular level as they move between their hosts and insect vectors.
That focus on the parasites’ complex life cycle is helping researchers understand when different genes switch on and off as the pathogens metamorphose th
CNSE spintronics lab research shows silicon can maintain a permanent magnetic field above room temperature, which could help to develop more effective magnetic semiconductors and future spintronic devices
Silicon is best known as the material used to make semiconductor computer chips with integrated circuits. Today, scientists at the College of Nanoscale Science and Engineering (CNSE) at the University at Albany published research that could lay the foundation for using silic
Have you ever sat through a painfully unfunny television ad that you knew was actually meant to be funny? Because one out of every five ads are designed to be humorous, chances are that you’ve witnessed a dud or two…or three. What makes an ad funny is the subject of research presented in the December 2004 issue of the Journal of Consumer Research by Josephine L.C.M. Woltman Elpers, a German marketing specialist, and her colleagues.
“Humor is one of the most widely used techniques in
Salton Sea find shares ’gene-jumping’ history with its oceanic relatives
Scientists at the University of Oregon have discovered a form of blue-green algae that lives independently in California’s Salton Sea, using near-infrared light for photosynthesis, according to an article published in this week’s online edition of the Proceedings of the National Academy of Sciences (PNAS).
“This new strain of Acaryochloris is unique because it is able to live on its own,” says UO
Fraunhofer IIS presented the first DRM chip design for car radios. This car radio solution will enable drivers to select their preferred radio program from hundreds of different radio stations. However, it is something more than purely listening to favorite music: the new radio formats offer multilingual support to ethnic news or talk programs. In this way, drivers will get local news or may listen to programs in foreign languages – at any time and any place.

Modification of Futures and Options on 2-year U.S. Treasury Note Eurex US, the fully-electronic U.S. futures and options exchange, today announced that it will expand its product suite of benchmark USD-denominated fixed income derivatives. On February 1, Eurex US will introduce futures on 3-year U.S. Treasury Notes and options on the futures. This makes Eurex US the only exchange worldwide to offer these products. With the introduction of the new product, Eurex US meets customer de
In the first study of its kind, researchers say half of patients undergoing stem cell transplantation exhibit signs of delirium, but the warning signs are subtler and can be easily missed by clinicians. The study, which appears in the February 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, says the level of distress, fatigue, and pain are associated with the severity of delirium.
Delirium is a temporary, acute change in a patient’s leve
Fewer than half of patients diagnosed with colorectal cancer had received a screening procedure at least six months prior to their diagnosis, according to a new study. Researchers writing in the February 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, further say almost 94 percent of colorectal cancer patients had either not undergone a colonoscopy at all, or not until having the procedure that led to their diagnosis.

Research by exercise scientists at Liverpool John Moores University (LJMU) may have an answer to the age old question of why women live longer than men.
On average, women live longer than men and women over 60 are now the fastest growing cohort in today’s ageing society. LJMU’s findings show that women’s longevity may be linked to the fact that their hearts age differently to men’s and do not lose their pumping power as they get older.

For the 350 million people chronically infected with HBV, the two therapeutic approaches currently available are immunomodulatory agents and antiviral chemotherapy. The first therapeutic agent was interferon-alpha (IFN-alpha), whose dual mode of action includes both antiviral and immunomodulatory effects. Unfortunately, extended IFN-alpha treatment is effective in no more than 15-25% of patients, and is associated with a wide spectrum of adverse reactions, although these limitations will be parti
The American Council for Headache Education (ACHE) launches its new Patient Education Page (PEP) in the journal, Headache. The page is a public service of ACHE, the patient education affiliate of the American Headache Society (AHS) and includes concise information that is useful for both patients and physicians. January’s page covers Menstrual Migraine: What You Should Know.
This first patient handout outlines migraine definitions, what to do, and various therapies that women ca
Imagine a home with “smart” walls responsive to the environment in the room, a digital camera sensitive enough to work in the dark, or clothing with the capacity to turn the sun’s power into electrical energy. Researchers at the University of Toronto have invented an infrared-sensitive material that could shortly turn these possibilities into realities.
