What's nature worth? New computer models tell all

...l and another next spring. In small teams, they'll link together the latest understandings of how forests, grasslands, wetlands, open ocean, and other ecosystem types function with detailed maps of where these natural communities occur and other geographic information. Next, these models will be informe...

Scientists identify protein with a crucial role in cell death

.... Previous research had already indicated that the link between PARL and Presenilin is negligible. It was understood that PARL is important to the cell's mitochondria, but the protein's particular function has remained unknown for a long time. 'Knock-out' mice To obtain insight into PARL's function, t...

UCI scientists find chlorine may contribute to ozone formation

...f Physical Sciences at UCI. "Because of the strong link between ozone and human health, we need to fully u...int the cause of these changes, finding no obvious link between chlorine levels and meteorological conditions such as wind, temperature or relative humidity...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...y, the researchers used a self-assembly process to link small synthetic molecules and a well-known catalytic monoclonal antibody, mAb38C2, through chemical bonding, a modification that resulted in the reprogramming of the specificity of the antibody to match the binding specificity of the small molecule. ...

Researcher studies, treats military with 'silent disease'

...ave more tattoos than civilian population, but the link between tattoos and HCV (hepatitis C virus), although it exists theoretically, has not been proven," she said. Currently no data exist in the United States indicating that people who have had tattoos are at increased risk for hepatitis C infection; h...

Major initiative proposed to address amphibian crisis

...logy. OSU researchers also were among the first to link amphibian declines directly to global climate change, in a process that traced global warming ultimately to a catastrophic egg mortality in the western toad of the Pacific Northwest Cascade Range. Work is continuing at OSU today on contaminants an...

Mechanism for neurodenegerative diseases linked to transport proteins

...nd why the terminals die before the cell body. The link to the activation of the JNK enzyme suggests a new therapeutic target that might limit, delay or perhaps prevent progressive neurodegeneration, the researchers conclude. ...

Brain region linked to fly slumber

...ulation over the purpose of sleep and its possible link with learning and memory. In a paper to be published June 8 by the journal Nature, a team led by Ravi Allada, assistant professor of neurobiology and physiology, shows that the so-called mushroom bodies are essential for sleep regulation in the fru...

A new view on Lyme disease: Rodents hold the key to annual risk

...ength of these findings suggests that the observed link between increased Lyme disease risk and high rodent densities indicates that important food sources--or predators--of the rodent hosts of nymphs will be valuable predictors of disease risk. ...

The secret lives of sea slugs

...ogists who study sea slugs in the laboratory is to link specific behaviors to their underlying neural controls. Information on behaviors and sensory cues that influence them is essential to the study of sensory systems, central processing, and motor systems, the basic neural elements that control behavior...

Free radical cell death switch identified

...neurons to die. The researchers also found a tight link between MST and another family of molecules called FOXO proteins. FOXO proteins turn on genes in the nucleus, the command center of the cell. Once stimulated by oxidative stress, MST acts in its capacity as an enzyme to modify and thereby activate t...

Inheriting a tendency to brain infection

"It's like giving insulin to a diabetic patient," he said. "You just replace the missing compound." Soon, children who come into the intensive care ...

Crohn's disease gene identified

...tive colitis." Previous genetic studies found a link between Crohn's disease and mutations in a gene known as CARD 15, but those mutations alone did not account for all of the genetic components of the disease. To identify additional genes associated with IBD, the international research team scanned ...

Scientists identify 36 genes, 100 neuropeptides in honey bee brains

...the honey bee as a model for sociogenomics, and to link molecular information to neurochemical and physiological data, we first must know the identities of the peptides used in the brain and the genes they are encoded by," Sweedler said. Using a combination of the newly available honey bee genome sequen...

St. Jude finds clues to hearing loss from chemotherapy

...ons in these animals," Zuo said. "That will let us link specific mutations to specific disruptions in the ear that cause hearing loss. The long-term goal is to try to manipulate or replace those genes in order to overcome those problems." Individual mutations might disrupt the work of a cascade of genes ...

Mayo Clinic study suggests that a central nervous system viral infection can lead to memory deficits

...Researchers were intrigued by the possibility of a link between picornavirus infections and memory loss. Little has been published in this area, Dr. Howe says. In the study, mice were infected with Theiler's murine (mouse) encephalomyelitis virus (comparable to the human poliovirus). Researchers looked ...
