H.E. Chief Olusegun Obasanjo, President of Nigeria, concluded a four-day NEPAD-Fish for All Summit by announcing adoption of the Abuja Declaration on Sustainable Fisheries and Aquaculture in Africa at the Secretariat of the Economic Community of West African States (ECOWAS).
The Declaration was agreed at an assembly of high-level government leaders that included the Vice President of The Gambia, Ministers of Fisheries from Mozambique, Ghana, The Gambia, Niger, Malawi, Egypt, C
A study published in the August/October issue of Current Anthropology, reports on new archaeological evidence regarding the identities of human sacrifice victims of the Moche society of Peru.
The Moche was a complex society whose influence extended over most of the North coast of Peru between AD 200 and 650. They are widely known for their life-like mold-made ceramics, beautiful metallurgy, mud brick pyramids, and iconographic depictions of one-on-one combat between Moche warr
The American Geological Institute (AGI), in conjunction with the American Geophysical Union (AGU), released an analysis of employment patterns and demographics of 2003 PhD recipients in the earth and space sciences.
Results from the survey show that employment opportunities remain stable for geoscientists going into the workforce, with 87 percent of respondents finding work directly related to their field. Starting salaries also remained steady or increased slightly in 2003, com
MIT technique is noninvasive
MIT scientists have developed a new dye that could offer noninvasive early diagnosis of Alzheimer’s disease, a discovery that could aid in monitoring the progression of the disease and in studying the efficacy of new treatments to stop it.
The work will be published in the Aug. 26 issue of Angewandte Chemie.
Today, doctors can only make a definitive diagnosis of Alzheimer’s-currently the fourth-leading cause of death in the
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists. While the properties of a common refrigerator magnet are not a great mystery, certain materials exhibit magnetic properties that do not fit within existing theories of magnetism. One such material inspired a recent theoretical breakthrough by physicists at the University of California, Santa Cruz.
In a paper scheduled for publication in the August 26 issue of the
Three confocal microscopic images of a cell stained with an antibody that detects the protein MAVS (left), Mito-Tracker (center), and an overlay of the green and red images (right) that indicates the mitochondrial localization of MAVS.
Researchers have discovered a surprise lurking inside mitochondria, the power plants that are present in every cell. It turns out that these powerhouses also contain a protein that triggers the immune system to attack viral invaders.

One of the most devastating diseases in sub-Saharan Africa almost disappeared in the late 1950s. That disease, African sleeping sickness, or trypanosomiasis, largely succumbed to heroic public health efforts — including relocating entire villages. But in the past several decades, because of post-colonial turmoil, the catastrophic illness has come back to ravage parts of Angola, the Democratic Republic of the Congo, the Sudan and other countries. In some regions, the tsetse fly-borne infection
Dräger Medical will unveil its new remote access concept at the 9th World Congress of the World Federation of Societies of Intensive and Critical Care Medicine in Buenos Aires, August 27-31, 2005. This new concept enables physicians to remotely access their patients’ cardiopulmonary status in near real time by using an integrated remote access solution.
Components of the new remote access concept include the Infinity® Gateway Suite, which provides the tools to export vital sig
EXPWAY of France has designed and launched FastESG™, a unique end-to end Electronic Service Guide solution over mobile and broadcast networks (GPRS, EDGE, UMTS, DVB-H), from server to terminal. FastESG™ is an XML-based software solution, built on rich metadata language such as DVB-CBMS, which guarantees an enhanced end-user experience (particularly in the field of TV viewing and multimedia entertainment). The company will be showcasing its technology at the IFA trade show in Berlin from 2 t
Researchers have discovered how the abnormal repetition of a genetic sequence can have disastrous consequences that lead to the death of neurons that govern balance and motor coordination. The studies bolster the emerging theory that neurodegenerative disorders can be caused by having extra copies of a normal protein, not just a mutated one.
People who are afflicted with the rare neurodegenerative disorder spinocerebellar ataxia type 1 (SCA1) suffer damage to cerebellar Purkinje
Scientists at Columbia University’s Lamont-Doherty Earth Observatory and the University of Illinois at Urbana-Champaign have ended a nine-year debate over whether the Earth’s inner core is undergoing changes that can be detected on a human timescale. Their work, which appears in the August 26 issue of the journal Science, measured differences in the time it took seismic waves generated by nearly identical earthquakes up to 35 years apart to travel through the Earth’s inner core.
PGC-1 mediates effects of nutrition on blood disease porphyria
Dana-Farber Cancer Institute researchers say they have uncovered a molecular explanation for the episodic attacks of irrational and demented behavior in porphyria, the disease believed to have afflicted “Mad” King George III, the British ruler blamed for the loss of the American colonies in the Revolutionary War.
The mental and physical symptoms of porphyria, a rare genetic blood disease which a number of
A newly discovered protein not only is vital to the immune system’s ability to fight off viral infections but also has been found in an unexpected location within the cell, causing researchers to rethink previous notions about the workings of the human immune system.
Researchers at UT Southwestern Medical Center said their findings may lead to new therapies aimed at preventing and treating viral diseases such as the flu, hepatitis, West Nile virus and SARS. The study is avai
Scientists have ended a 9-year-old debate by proving that Earth’s core rotates faster than its surface, by about 0.3 to 0.5 degree per year.
“Extraordinary claims require extraordinary proof,” said Xiaodong Song, a professor of geology at the University of Illinois at Urbana-Champaign and corresponding author of a paper to appear in the Aug. 26 issue of the journal Science. “We believe we have that proof.”
Earth’s iron core consists of a solid inner core about 2,400 kilo
The malaria parasite Plasmodium falciparum uses different pathways to invade red blood cells, evading the body’s immune system and complicating efforts to create effective vaccines against the disease. A research team led by Australia’s Alan F. Cowman, an international research scholar with the Howard Hughes Medical Institute, has identified a gene that the parasite uses to switch back and forth between invasion pathways.
Researchers from the Scripps Research Institute in La
Achieving equality between the sexes can be a challenge even for single cells. Since evolution began removing bits of male DNA to create the “Y” chromosome, males have had a single copy of certain key genes on the X chromosome, whereas females have two. Normally this would lead females to produce twice the amount of some proteins, which could be fatal, but cells have developed ways to prevent this. Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg have now made a bre
