Dopamine sheds new light on drug addiction

A paper published in the current issue of Science has challenged beliefs about the role of dopamine in the brain, which could lead to new treatments for Parkinson’s disease, schizophrenia and drug addiction. The research suggests that dopamine has a far wider, less specialised role than previously hypothesised.

Genome clues to amoebic dysentery

Each year, there are an estimated 50 million cases of amoebic dysentery, causing up to 100,000 deaths, mostly in developing countries. On Thursday 24 February 2005, researchers at the Wellcome Trust Sanger Institute and their colleagues reported in Nature magazine the genome sequence of the parasite that causes the disease, Entamoeba histolytica.

Encouraging results in wet age-related macular degeneration study

Novadaq Technologies has announced that Dr. Giovanni Staurenghi, (Associate Professor of Ophthalmology, Department of Otorhinolaryngological and Ophthalmological Science University of Milan, Italy), reported preliminary data on 24-patients in an on-going study using the Company's proprietary technology to treat wet Age-Related Macular Degeneration (AMD).

Discovery of a protein JBP2, an important tool for African sleeping sickness research

Sixty million people in 36 countries of sub-Saharan Africa are threatened daily by a deadly parasitic disease known as African sleeping sickness.

Experts on chronic lymphocytic leukemia (CLL) review current scientific knowledge

When the most common adult leukemia in the United States was last reviewed by the New England Journal of Medicine (NEJM) in 1995, it was seen through the eyes of theories that dated back to the 1960s.

EuroVacc 02 HIV Vaccine trial begins

The European Vaccine Effort against HIV/AIDS, has announced that a phase I clinical trial of novel investigational vaccines comprising DNA-HIV-C and NYVAC-HIV-C for the prevention of HIV infection has started in Lausanne and London in February 2005.

Speed dating offers researchers a systematic look at the genuine behavior of people selecting mates

It seems that the heart wants what the heart wants -- and it can figure it out fairly quickly, according to evolutionary psychologists at the University of Pennsylvania. The researchers studied dating data from 10,526 anonymous participants of HurryDate, a company that organizes "speed dating" sessions, and found rare behavioral data on how people genuinely act in dating situations.

New primate-specific gene family that spans about 10% of human chromosome 2

A team of scientists led by Peer Bork, Ph.D., Senior Bioinformatics Scientist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2.

New insights into how a language is born

How is a language born? What are its essential elements? Linguists are gaining new insights into these age-old conundrums from a language created in a small village in Israel's Negev Desert.

Studying monkeys social judgments could provide clues to autism

Researches have found that monkeys will "pay" juice rewards to see images of high-ranking monkeys or female hindquarters. They say their research technique offers a rigorous laboratory approach to studying the "social machinery" of the brain and how this machinery goes tragically awry in autism -- a disease that afflicts more than a million Americans and is the fastest growing developmental disorder.

Startling results from new biomedical research will smooth path to the market place

Researchers have discovered how to convert liver cells of mice into pancreatic cells using a single injection. This may eventually lead to a cure for diabetes. Dr. James Mittra, one of the organisers of an international conference in Edinburgh on the Evolution of the Life Science Industries asks, “How does the pharmaceutical industry respond to this kind of work? They are primarily interested in treatments, not cures. Do they see this kind of research as a threat?”

Melanopsin plays a key role in the inner workings of the eye

A Brown University team has found that a protein called melanopsin plays a key role in the inner workings of mysterious, spidery cells in the eye called intrinsically photosensitive retinal ganglion cells, or ipRGCs.

Biochip for detection of inflammatory bowel disease

At the III International Symposium on Advanced Therapy for Chronic Inflammatory Bowel Disease, held in Madrid, the biotechnological company, Progenika, presented a DNA-chip the purpose of which is the optimisation of the diagnosis, prognosis and treatment of patients with inflammatory bowel disease (Crohn’s disease and Ulcerous Colitis).

Theory on evolution of essential genes is overturned

A gene passed on by fathers that plays a vital role in helping fertilised eggs to develop into adults has helped scientists overturn the idea that essential genes have always been part of the genetic makeup of a species.

Evolutionarily ancient enzyme-repair system used to identify type of DNA damage responsible for the onset of skin-tumor development

In a finding that broadens our insight into the cause of certain kinds of UV-induced skin cancer, researchers at Erasmus University Medical Center (Rotterdam, The Netherlands) have employed an evolutionarily ancient enzyme-repair system to identify the principal type of DNA damage responsible for the onset of skin-tumor development.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

Modern humans have sloppy gene control mechanisms which can make us susceptible to diseases

Our evolutionary ancestors’ lack of choice in the mating game has left modern humans exposed to disease, according to new research published in the journal PLOS Biology today.

Psychiatric disorders detected using blood test

ChondroGene Limited reported today that a paper entitled "Assessing the Validity of Blood- Based Gene Expression Profiles for the Classification of Schizophrenia and Bipolar Disorder: A preliminary Report" is available online on the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics' website.

Missing sequence of the human Y chromosome may contain genes controlling stature and tumor development

Scientists have reported in the journal Genome Research that they have successfully cloned and characterized a previously intractable DNA sequence: a 554-kilobase-pair genomic segment near the centromere of the human Y chromosome. This sequence contains eight putatively active genes that could be implicated in sex-associated height differences and gonadal tumor development.
