Monkeys don't go for easy pickings

...tive ones. Although the sakis took more risks by traveling further by expending more energy and exposing themselves to predators for longer periods choosing more fruit-rich sites allowed the group to limit feeding competition amongst themselves and to stick together to maintain intergroup dominance. The...

Tumor painting revolutionizes fight against cancer

... prostate cancer model, as few as 200 cancer cells traveling in a mouse lymph channel could be detected. Chlorotoxin:Cy5.5 is applicable to many cancers, but is especially helpful to surgeons operating on brain tumors. Not only would it reveal whether theyd left behind any bits of tumor, it would also help t...

Coaching computer canines in clambering

...e Schaal's dogs can now move, but not very fast: traveling at 1.6 centimeters a second, a little faster than the old 1.2 cm/sec of the old Mars Sojourner robot. The goal in the next phase of the study is to triple the speed and double the difficulty of the terrain - have the dogs not just traverse rocky gr...

Female iguanas pay high costs to choose a mate

...ible for females to assess many candidates without traveling far. Vitousek and colleagues measured how much energy female iguanas expend on mate choice in the wild using miniaturized data loggers developed by Anthony Woakes at the University of Birmingham. They found that females devote a surprising amount ...

18-year-old Singaporean student to present stem cell research paper at conferences in US and UK

Most young Singaporean students who will be traveling next week and during July will be vacationing, relaxing and sightseeing. But not 18-year old Nicholas Tan Xue-Wei, who will soon depart for the U.S. to attend and present a research paper at The 2007 World Congress in Computer Science, Computer E...

... England Journal of Medicine. The woman had been traveling in the Peruvian Andes. She suffered from potentially life-threatening anemia, an enlarged spleen and a high fever for several weeks, as do victims of malaria and typhoid. The Andes are also home to another Bartonella species, spread by sand flies. Th...

Additionally, the CAREER award could help create advancements in the medical industry as Wenk and her students look to develop novel computational tools to analyze two-dimensional electrophoresis gels. The gels pro...

Molecular motors may speed nutrient processing

...ties. At the time, Tyska knew that the core bundle traveling up the center of the microvillus was an array of the structural protein actin, and that the ladder-like "rungs" connecting the actin bundle to the cell membrane were composed of the motor protein myosin-1a. This myosin, though related to the myosin i...

Dinosaur hearing, listening to muscle noise, quieter cubicles

... sensors follow the passing of natural shear waves traveling along the muscle fibers. By the way, the Scripps scientists were originally interested in underwater noise effects and only later adapted their work to noise in muscle.

Simple equations track Listeria trails

...enoy as soon as he saw Theriots movies of Listeria traveling in the two-dimensional world of a microscope slide. Some bacteria spun in circles, others followed a sine curve, some followed a path like the cloverleaf exchange on a highway. The circles, he thought, were easy to explain. If an actin filament pushe...

Newborn neurons like to hang with the 'in' crowd

...pecialized structures called synapses. As a signal traveling along a nerve branch arrives at the pre-synaptic area, it releases a chemical signal. The signaling molecules travel across the synapse and induce a signal on the neighboring, receiving nerve fiber or dendrite. A typical neuron sports about 7,000 syn...

Scientists do not know why some juvenile turtles make the journey to Northern Europe, but believe they may simply be driven by the North Atlantic current system. The eggs of Kemps ridley turtles were harvested ...

Ocean's 'twilight zone' may be a key to understanding climate change

...day, but they are swept sideways by ocean currents traveling many thousands of meters per day. To collect sinking particles, oceanographers use cones or tubes that hang beneath buoys or float up from sea floor. That, Buesseler said, "is like putting out a rain gauge in a hurricane." While many studies have i...

Researchers at the University of Southern California's Keck School of Medicine cite two general types of personal risk factors associated with late cancer diagnosis: socio-economic, or cultural, factors re...

Marine scientists monitor longest mammal migration

...bor, Maine. The scientists found some humpbacks traveling from Antarctica across the equator to as far north as Costa Rica to overwinter, a distance of approximately 8,300 kilometers or about 5,157 miles. The authors noticed that the presence of cold water along the equator coincided with the occurrence of...
