Invariant properties in coevolutionary networks of plant-animal interactions

...w the complexity of this type of ecosystem network escaped scientists' attempt to study them: just imagine all the interactions that can take place in a highly diverse tropical rainforest. Many insects, bats, and hummingbirds pollinate flowers and frugivorous vertebrates- like toucans or monkeys- disperse p...

Purdue researchers discover basis for biological clock

... on other projects, but the biological clock never escaped his mind or efforts completely. Then an examination of how cells grow led him to the discovery. The Morrés found that cells increase in size at a periodic rate -- they enlarge themselves for 12 minutes, then rest for 12 before growing again. ...

'Small RNA' research cited as breakthrough of the year

...seless DNA. They are extraordinarily tiny and have escaped notice, until recently. However, unlike messenger RNAs, small RNAs are not translated to produce proteins. Their roles are more devoted to control of the process of gene expression or chromosome activity. "I think one of the most exciting aspects of ...

18F-FDG PET predicts lymphoma treatment outcome

...sult of small amounts of disease that remained and escaped detection because of the resolution limitations of the coincidence PET scanner used in the study. In a commentary accompanying the article in JNM, Val Lowe, MD and Gregory Wiseman, MD, of the Department of Radiology at the Mayo Clinic took issue wit...

Gene may protect abused kids against behavior problems

...t some people exposed to pathogens from mosquitoes escaped malaria, science would never have known about the gene for susceptibility to the disease," Moffitt explains. By turning to maltreatment -- an environmental pathogen known to bring about antisocial behavior -- the UW-Madison researchers were able to ...

Sea Grant research shows electric barrier may stop Asian carp

...ught here for use in aquaculture in the 1970s, and escaped into the Upper Mississippi River System. The populations of these species have increased dramatically in some areas. "Asian carp consume zooplankton, which all fishes typically feed on in their juvenile stages, so they have the potential to adversely...

Chinese tallow tree invades Texas prairies

...crop. That project was unsuccessful, and the trees escaped from cultivation. Siemann is concerned about the spread of Chinese tallow trees, because once they replace bluestem grasses, sunflowers, blazing stars and other plants found in the prairies, those species and their associated animal fauna will not...

The anti-inflammatory effect of apoptotic bodies

The ubiquitous process of apoptotic cell death escaped the notice of cell biologists for decades, largely because cells that die by this mechanism are efficiently removed by phagocytosis in a process that provokes no local inflammation. Indeed, as Henson and collaborators have argued, the clearance of ap...

UNC botanist spearheads ongoing effort to curtail movement of pest plant species

... shrub planted as hedges throughout the South that escaped and crowded out numerous indigenous species. Privet has formed impenetrable thickets and become almost the only plant in the understory of many Southern bottomland forests. Another is the Brazilian pepper, which transpires so much water into the atm...

Sea Grant study finds Chinese mitten crabs appear free of human parasite lung flukes

...es may flourish in a new habitat because they have escaped many of theirnative predators and parasites." Lung flukes are parasites with a complex lifecycle that requires them to infect two intermediate hosts before they mature into adults inside a warm-blooded animal or person. Flukes in their "larval" form...

Impact of genetically engineered fish subject of U of Minnesota study

... Tilapia are not native to Thailand, but some have escaped into natural rivers and wetlands and established feral populations. The project will measure the likelihood that genetic material will flow from the introduced genetically modified tilapia to the existing feral populations of the fish. The impact of...

Blocking 'engulfment' gives dying cells new lease on life

...ll death signal increased the number of cells that escaped death to nearly 20%. Moreover, some 40% of cells slated for death in these animals survived outright, never displaying signs of death. In essence, when the engulfment machinery was disabled, cells lived that otherwise would have died. This finding in...

Unleashing GMO's into the environment

...ether a foreign gene would spread if a GM organism escaped or was released into the wild. So far Muir and Howard have only tried their model on fish, but in a paper published this week in The American Naturalist (vol 158, p 1), they say the same principle would work for any animal or plant species. The m...

Ginsburg sites several recent examples in Asia, Europe and Mexico, resulting in the slaughter of millions of cows, pigs and poultry, as well as trade sanctions. Her article empha...

Prairie fire--UIC-style

Nyberg has participated in or supervised more than 20 controlled prairie burns in different locations. "The fire kills the above-ground part of woody vegetation," he says. Woody, as opposed to grass-stemmed ...

Researchers reveal contaminated factory sites unknown to regulators

...ey added that some very small companies might have escaped their notice because they were not listed in the directories. Lead poisoning, especially in children, is often attributed to lead-based paint, according to Eckel. "But in the local areas where these sites exist, they may explain at least part o...

UCSF-led study points to pivotal, early event in cancer development

These markers, they say, could ultimately be used to evaluate the susceptibility of epithelial cells to becoming cancerous and thus point to cells that could be potential targets...

High-pressure crystallization of salts within fractures may provide an efficient mechanism for differential plate separation, horizontal movement, and formation of new fractures on the surface of Europa.

Scientists reveal new HIV vaccine target

"The new virus was no longer recognized by the early Tat-specific killer T cell response. This is an example of Darwinian selection for viruses that evade i...

But the sites on the virus where those compounds work can mutate fairly easily, making the drugs resistant with t...
