Twenty-eight years after intense selective logging stopped in the region now known as Ugandas Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. The logging practice, scientists report in a new study, changed the ecological balance for these monkeys, leading to behavioral changes and opening the door for multiple parasitic infections.
The researchers focused on three primate species, collecting 1,076 fecal samples from the heavily logged area and from an undisturbed, nearby forest from August 1997 to August 2002 as part of a longitudinal study of loggings impact. The samples came from red-tailed guenon, red colobus (Piliocolobus tephrosceles) and black-and-white colobus (Colobus guereza) and were analyzed for the eggs and larvae of worms and protozoan cysts.
The study appears online ahead of publication in the Journal of Applied Ecology.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
