Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

...is having a large impact on local communities that depend so much on healthy fisheries," says Charles Peterson, a professor of marine sciences biology and ecology at the Institute of Marine Sciences, University of North Carolina at Chapel Hill and co-leader of the study. The research builds upon an ear...

Bird flu -- Call for antiviral drugs to be shared

... and its containment. They conclude that much will depend on the 'reproductive number' (a measure of how many people an infectious individual infects on average) of the new virus that emerges. If this number is low, it will take many months before the virus spreads w orldwide and there will be plenty of tim...

Stem cell identity in culture may strongly depend on the cellular microenvironment

...hat the stem cell identity in culture may strongly depend on the cellular microenvironment. These observations are in line with the currently emerging view that differentiation is context dependent rather than a pre-programmed attribute of the cells. In practice, this work provide a rationale to research ...

Mitochondrial genes move to the nucleus -- but it's not for the sex

...ain said. "When you have two successful genes that depend on each other, it's best for them not to be in an environment in which they will recombine. It would be like breaking up a good musical duo." Mitochondrial and nuclear genomes replicate separately, and a new and beneficial mutation in the mitocho...

Long-lived deep-sea fishes imperiled by technology, overfishing

...d, "except we don't ‘replant' the fish. We have to depend on the fish to replenish themselves. And the habitat that used to provide them protection ?the deep ocean ?is now accessible to fishing because of new technologies." Among the most recognized deep-sea species at-risk are orange roughy and Patagoni...

Stopping plants from getting sick

...tudy how pathogens infect crop plants. These fungi depend on the infection of a plant to complete part of their life cycle. But once that part of their life is over, they can be removed from the plant to be studied in the laboratory. What Kronstad discovered was the method that these fungi use to invade ...

Ethanol vehicles pose a significant risk to human health, study finds

...e explained. ''In addition, overall health effects depend on exposure to these airborne chemicals, which varies from region to region. Ours is the first ethanol study that takes into account population distribution and the complex environmental interactions.'' In the experiment, Jacobson ran a series of ...

Inflammation may play role in metastasis of prostate cancer

...lls have found a way to turn off Maspin, which may depend on invasion of the tumor with RANK ligand-producing cells that activate IKKa," said Karin. Malignancies progress through stages. In early, non-metastatic tumors, a high level of Maspin is present, but it is turned off in late stages. Early tumors...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...ctive preventative treatment with the vaccine will depend on the long-term and broad protection the vaccine can offer against cancer-causing HPV types. High Sustained Efficacy of a Prophylactic Quadrivalent Human Papillomavirus (HPV) (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine against ...

Scientists discover stage at which an embryonic cell is fated to become a stem cell

...e or outside of the embryo. And those differences depend on the orientation and order of the very first cleavage divisions of the embryo. Professor Zernicka-Goetz said, "Our findings were surprising since they showed that cells of the mammalian embryo first start to differ from each other much earlier in...

Bisexual fruit flies show new role for neurochemical

...flies' ability to discern one sex from another may depend on the number of receptors on the surface of nerve cells, and the number of receptors is controlled by levels of a ubiquitous brain chemical, University of Illinois at Chicago researchers have found. Everything from the ability to concentrate, perce...

How trees manage water in arid environments

...what is happening to the water that so many people depend on. In a desert region, such forests are found only at the tops of mountains because only there does precipitation exceed evaporation enough for forest vegetation to survive. Understanding surface-atmosphere interactions is important to understand...

Glucose triggers brain cell death in rats after hypoglycemic coma

... it may be that glucose is the culprit. And it may depend on how much glucose is put in." In terms of clinical science, Swanson observes that "as clinicians, our first reaction when we see a patient in hypoglycemic coma is to give lots of glucose, fast. But our rodent model makes it clear that overshooti...

Intelligent materials to regenerate bone tissue

...afts or implants, required to mitigate the damage, depend decisively on the materials used. The European Nanobiocom project, led by INASMET-Tecnalia with the help of others, is working on the regeneration and repair of bone tissue. Seven other bodies, leaders in innovation within this specialism, are also ...

Newborn neurons like to hang with the 'in' crowd

...crux of the study: the survival of new neurons may depend on the ability to compete out the older existing neurons," says Gage. Earlier studies had shown that if young neurons fail to receive signals from other brain cells they wither and die. By connecting to functional synapses, the newborn neurons ensure...

Scientists: As rainfall changes, tropical plants may acclimate

...anisms and one mechanism in this study" and plants depend on many different mechanisms to coexist, some of which may also change with changing rainfall. The scientists researched plant growth at six sites on the slopes of Mount Haleakala, a volcano on the island of Maui. The sites were ideal because they...

Alien plants attack using 'resource conservation' as weapon, researchers say

... evolved there." Smart plant growth Plants depend on sunlight, nutrients and water to survive, and a shortage of any one of these will restrict how fast they can grow. When plants use these inputs more efficiently, however, they can photosynthesize-and thus grow and spread-faster, according to Funk ...
