Corals switch skeleton material as seawater changes

.... The aquatic animal's sensitivity to such changes poses questions about its evolutionary history, as well as the future of the ecologically important coral reefs that it builds, Ries said, especially at a time when seawater is changing in response to global warming and the buildup of carbon dioxide in the...

Innovative method for creating a human cytomegalovirus vaccine outlined

...hey reach 40 years of age, but the virus generally poses little threat to them. The exceptions are AIDS patients, transplant recipients, and others with compromised immune systems are at risk for complications. The virus is a member of the herpes virus family, which includes the herpes simplex viruses, the...

Gorilla susceptibility to Ebola virus: the cost of sociality

... the factors affecting the threat the deadly virus poses to great apes. The work is reported in the July 12th issue of the journal Current Biology by a team of researchers including Damien Caillaud and colleagues from the University of Montpellier and the University of Rennes, France. Ebola virus is ex...

Study supports 'urgent' need for worldwide ban on lead-based paint

...earchers say that this lead-based paint production poses a global health threat, and a worldwide ban is urgently needed to avoid future public health problems. Lead is a malleable metal previously used to improve the durability and color luster of paint used in homes and other buildings and on steel stru...

Cornell researchers find serious fish virus in Northeast for first time

...sh species, was discovered in upstate New York. It poses no threat to humans. In May 2006, the researchers, in collaboration with the New York State Department of Environmental Conservation (DEC), isolated the virus in round gobies that died in a massive fish kill in the St. Lawrence River and in Ironde...

Fish virus in Northeast spreading to other fish species

...l anemia and hemorrhaging in many fish species but poses no threat to humans or other animals. "The situation right now is that we still have fish dying in Lake Ontario," said Geoffrey Groocock, a postdoctoral associate at Cornell's Aquatic Animal Health Program. "We have detected the virus in other f...

Plant-derived vaccines safeguard against deadly plague

...red some resistant strains to antibiotics and that poses a concern, especially if plague would be used as a bioweapon," said Luca Santi, a research assistant professor at the institute and lead author of the study published in the early online edition of the journal Proceedings of the National Academy of S...

Scientists re-engineer a well-known antibiotic to counter drug resistance

...e continued rise of vancomycin-resistant infection poses a serious threat to hospital patients in the U.S. and around the world," Boger said. "These infections not only increase the length of hospital stays, but they raise patient mortality rates as well. Our successful synthesis of a novel vancomycin anal...

Access to existing medical treatments could save more lives than spending to improve the treatments

...inorities and disenfranchised patients. The study poses a contrast between efficacy, or how well a treatment works, and what they call the "fidelity of health care." Independent of the efficacy, fidelity is the extent to which the health care system provides patients the precise interventions they need, d...

Langerhans cells regulate immune reactions in the skin

Langerhans cells may function generally to prevent excessive responses in the skin. "Failure of this mechanism could result in chronic infla...

Novel protein complex enables survival in hostile environment

...ectron-donating partners." "The existence of Fsr poses several questions that are important in the context of evolution of metabolism and enzyme mechanism," Mukhopadhyay said. "We do not know whether the splitting of the fsr gene gave rise to the sulfite reductases of the bacteria and energy transducers ...

First big influenza genome study reveals flu evolution

...sequence 100 influenza genomes weekly. Influenza poses a major public health problem. In an ordinary year, the flu kills up to a half million people worldwide. In the U.S., a typical flu season brings 36,000 deaths and 114,000 hospitalizations. Over the past century, three pandemics--in 1918, 1957, and ...

Deep treasure to be found in Oculina Bank

"The [SAFMC] has led the nation in managing deepwater coral ecosystems by setting up this reserve, it is now up to scientists to show if it's working," says expedition leader Andy Shepard from the National Oceanic and Atm...

K-State researchers study insects' immune system

...e and then transfer it to the next person it bites poses an interesting concept for researchers. For the disease to spread, it has to survive for a certain period of time in the mosquito. The question is, how does the pathogen survive? For a disease like malaria, the parasite has to live in an insect's bl...

Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

...l cautions that massive die-off of dendritic cells poses a possible risk of immune system suppression, a condition that could leave patients vulnerable to infections or other diseases. "But our studies show that though many dendritic cells were destroyed, some still remained," he said. Their tests also r...

Asian immigrants in NYC not receiving HIV education at religious institutions

...Asian religious institutions said they believe HIV poses only a minimal risk for the Asian community, Chin and colleagues found, and most respondents said that HIV prevalence was relatively low or nonexistent in their respective communities. Others felt the community would be too uncomfortable discussing H...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

...e result of the hurricane and is still in the city poses a risk of infection. "Decaying bodies pose very little risk for major disease outbreaks," says Berkelman. Furthermore, mosquitoes do not spread disease by feeding on dead bodies. There is, however, a risk of mosquito-borne diseases such as West Nile...

Quick identification needed to save Florida's citrus industry from devastating disease
