New roles for growth factors: Enticing nerve cells to muscles

...ssion Laboratory, "but that piece by piece, we are uncovering general principles that ensure that the developing nervous system establishes proper neuronal connections." Understanding how axons find their destinations may help restore movement in people following spinal cord injury, or those with motor neuron...

New approach to vaccine development provides potent, long-lasting immunity

...admehr. As a next step, the team is interested in uncovering which parts of the brain are responsible for slow-learning. They hope that teasing this system apart will not only improve the understanding of brain function, but also tailor therapy strategies to target slow-learning and increase recovery of muscle...

Robotic joystick reveals how brain controls movement

Cuttlefish masters of disguise despite colorblindness

...r colleagues suspect might be a critical factor in uncovering what determines camouflage patterning in cuttlefish. Despite these results, the vexing question of how cuttlefish master the task of camouflage in low-contrast, color-rich environments such as those found at shallow depths of water, remains to be an...

Earth Rx: A microbial biotechnology prescription for global environmental health

...ts on the ocean's floor to arctic permafrost. Now, uncovering and categorizing this abundant biodiversity is one of the chief goals of scientists in the field of microbial ecology ?and may be the key to helping the planet –by putting these rich microbial communities to work to help serve the needs of society th...

The world's deepest dinosaur finding - 2256 metres below the seabed

...egians found one using a drill. The somewhat rough uncovering of Norway's first dinosaur happened in the North Sea, at an entire 2256 metres below the seabed. It had been there for nearly 200 million years, ever since the time the North Sea wasn't a sea at all, but an enormous alluvial plane. It is merely a co...

MIT: Oceans are a major gene swap-meet for plankton

...search, led by MIT Professor Sally W. Chisholm, is uncovering a challenging new facet of evolution, helping scientists see how photosynthesizing microbes manage to exploit changing conditions such as altered light, temperature and nutrients. The work will be reported in two articles in the March 24 issue of S...

Marine mammals are on the frontline of failing ocean health

...ding scientists, physicians, and veterinarians are uncovering new links between land-based pollution and diseases in marine mammals, with implications for human health. "Marine mammals are providing early clues of our unseen impact on the sea," says Paul Sandifer, Chief Scientist for the new Oceans and Human H...

Boosting newborns' immune responses

...r bio-terrorist threat, Levy adds. Levy's team is uncovering other differences between the newborn and adult immune systems that could lead to additional targets for drugs or vaccines. A related paper, to be published soon in the journal Pediatric Research, finds that when newborns' TLRs are stimulated during ...

Scientists discover interplay between genes and viruses in tiny ocean plankton
