Measuring the impact of post-genomics on Mediterranean populations

A recent Genomed-Health 2005 workshop in Tunisia, supported by the European Commission, highlighted the role of the life sciences in improving health in countries bordering the Mediterranean Sea. Delegates at the event also discussed the importance of Euro-Mediterranean partnerships in order to capitalise on post-genomic research. The life sciences ?in particular following the mapping of t...

Oldest cranial, dental and postcranial fossils of early modern European humans confirmed

The human fossil evidence from the Mladec Caves in Moravia, Czech Republic, excavated more than 100 years ago, has been proven for the first time, through modern radiocarbon dating, to be the oldest cranial, dental and postcranial assemblage of early modern humans in Europe. A team of researchers from the Natural History Museum in Vienna, from the University of Vienna in Austria and from t...

The molecular post office inside the cell

For most proteins, there is a particular place inside a cell where they carry out their function. But how do they get there? Scientists from the Charité Berlin, the University of Heidelberg, and the Max Planck Institute for Molecular Genetics in Berlin have now been able to visualize the structure of a "molecular machine" involved in protein sorting using cryo-electron microscopy and single part...

The bioweapon is in the post

You might think it would be difficult for a terrorist to obtain genes from the smallpox virus, or a similarly vicious pathogen. Well, it's not. Armed with a fake email address, a would-be bioterrorist could probably order the building blocks of a deadly biological weapon online, and receive them by post within weeks. That's the sobering reality uncovered by a New Scientist investigation in...

Nano springs eternal; Protozoan 'engine' posts nano records

Looking through his handmade microscope in 1702, it was Anton van Leeuwenhoek who first described the workings of a nano machine. He observed the rapid contraction of a stalk tethering the cell body of a tiny protozoan, Vorticella convallaria, to the surface of a leaf. Little did van Leeuwenhoek imagine that more than 300 years later, the biological spring that drives Vorticella would set records...

Ultra low-dose estrogen shown safe for post-menopausal women

A study led by researchers at the San Francisco VA Medical Center has shown that extremely low doses of estrogen had no ill effects on the cognitive abilities or general health of older women over the course of two years. "This is exciting. It shows that women can take estrogen safely," observes lead author Kristine Yaffe, MD, chief of geriatric psychiatry at SFVAMC and associate professo...

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax

Anthrax vaccine administered in combination with a short course of antibiotics completely protected nonhuman primates from inhalational anthrax, the most lethal form of the disease, according to scientists at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). In a collaborative study involving USAMRIID and the National Institute of Allergy and Infectious Diseases...

Recycled paper and compost could both be key tools to control plant disease

New research by the University of Warwick should have gardeners and commercial growers competing for both recycled paper and organic waste composts. The University's plant research department, Warwick HRI, is finding that recycled paper based composts are proving to be a major weapon in the fight against a range of plant diseases. A University of Warwick research team under Professor Ralp...

Air travel and flu: Post-9/11 restrictions delayed start of season

The onset of the flu season in the USA has been shown to be influenced by air travel. After flights were restricted following the 9/11 terrorist attacks in 2001, the flu season started about two weeks later than usual. In both the northern and southern hemispheres, influenza epidemics occur annually during the winter flu season. Given the concerns about global epidemics of serious strains...

Post oak grasshoppers emerging

They're not afraid of heights, they're voracious, and Dr. Spencer Behmer wants to know if you've seen them hanging out in oak trees or on your house. If you haven't heard of them, don't feel alone. Until recently, most Texans hadn't....
