Scientists elucidate the kinome of key model organism

...al utilized the power of bioinformatics, a cutting edge scientific technique which employs databases and computer algorithms to allow researchers to gain information and compile data about genes and kinases in a fast and efficient way, which can be very useful for drug discovery and development. Accord...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

...some of the cellular infrastructure at the leading edge of a cell allowing the cell to form a pliable footlike structure (lamellipodia). Previous work by this Mayo Clinic team was the first to correlate the formation of lamellipodia with wave-induced reorganization within a cell. ...

'Scent of a woman' tells male redback spiders to find a mate

...ers (Latrodectus hasselti) that give these guys an edge in their deadly dating game. The study in the April 4 issue of Current Biology reports that males develop faster based on the population density of males and females around them -- the first time such a phenomenon has been shown in any animal. "It s...

Vital ocean prey play active role in environment

...ly separate. In summer, adults remain close to the edge of the continental shelf, which allows them access to open-water food supplies. Females carrying eggs move offshore to deep water to spawn, where the embryos sink. The embryos hatch into free-swimming larvae at depth, then swim upward over the course...

Uncovering sex-change secrets of black sea bass

In a former cowshed on the edge of the University of New Hampshire campus, David Berlinsky, assistant professor of zoology, peers into a big blue plastic tub. Inside, black sea bass circle slowly in the dim light. The converted barn is now an aquaculture research facility for the C...

A new focus for the mechanism of nerve growth

... that is constantly being assembled at the leading edge and moved rearward, powered by a myosin II motor located at its back end. But, the networks making up this actin treadmill are constantly being recycled at the back end, and actin molecules are freed to complete a "virtual belt" cycle and be used aga...

NJIT engineer poised to take stem cell research a step forward

...on the spinal cord research. "She's at the leading edge of modern biology and if anyone can take stem cell research forward, she can." ...

Amazon rainforest greens up in the dry season

...want to look harder at the transition zones at the edge of the rainforest to see whether different kinds of disturbance cause different growth patterns." ...

Next good dinosaur news likely to come from small packages

... of Science annual meeting Friday explores cutting edge technology used to divine new information from ancient bits of bone and tissue. One of the field's hottest topics is whether proteins and DNA survive the test of time. Ostrom is putting her bet on proteins and is working with an international team...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...e along the continental shelf of Antarctica at the edge of the ice pack. Southern elephant seals, in contrast, forage widely in the offshore waters. The SEaOS project led by SMRU's Fedak is deploying electronic tags on elephant seals at three locations in the Southern Ocean. The oceanographic data gathe...

Predators keep the world green, ecologists find

...g in the interior sees light streaming in from the edge around the entire perimeter. There is almost no leaf litter, and the ground is bright red from the subsoil brought to the surface by leaf-cutter ants. "Dead twigs, branches and vine stems from canopy dieback litter the ground, and in places lie in h...

Superconducting magnet attracts molecular research

...ades, and this magnet helps keep us at the cutting edge of research," said Pochapsky. "It's an investment in the future." ...

Research: Snails were overlooked contributors to marsh destruction

...snails moved off the flats and concentrated on the edge of the die off, where healthy grass remained. This migration resulted in the formation of grazer "fronts," which attacked and destroyed more marsh in "waves" of runaway consumption, the authors write. A team of scientists from UF, the Netherlands In...

Bats use touch receptors on wings to fly, catch prey, study finds

...xample, when Zook removed hairs along the trailing edge of the wings and on the membrane between the legs, the bats were able to fly and turn effectively, but they tended to pitch forward because they couldn't control their in-flight balance. Zook's research also points to the importance of a second type...

Envisat radar surveillance protects endangered prehistoric fish

...and seals. Toothfish dwell in deep waters on the edge of coastal shelves and sea mounts. Individual toothfish can live for 40 years but take a decade to reach adulthood: their slow-maturing character makes them especially vulnerable to overfishing. As toothfish numbers have crashed in heavily fished...

Science's Breakthrough of the Year: Watching evolution in action

..., Mars, a comet, an asteroid, Saturn, and the very edge of the solar system, planetary discovery soared in 2005. The high point in a year of highlights may be the landing of the European spacecraft Huygens on Titan, Saturn's largest moon. Huygens' trip to Titan revealed a world where infrequent but drench...

Scientists observe how a close bond activates the immune system

...t the new work shows that it is actually the outer edge of immunological synapse that boosts activation, not the center. Dr. Dustin's group is now conducting additional experiments to see if dendritic cells actively present proteins to T cells in patterns that stimulate the periphery of the bull's eye i...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

...small increases in transmission it gave viruses an edge over other co-circulating dengue viruses that did not experience enhancement. Counter-intuitively, larger increases in transmission resulted in more extinctions of the enhanced virus. "Dengue dynamics are similar to predator-prey systems in ecology....

Wright bros. upstaged! Dinos invented biplanes

...rlocking barbules to keep their shape. The leading edge of each long feather was narrower than the trailing edge, which helped streamline the body in flight. The hooked, interlocking barbs gave strength and flexibility to the feather and prevented air from passing through it in flight. Some present-day ...
