A dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today.

Calcium may be the key to understanding Alzheimer's disease
Researchers at the University of Pennsylvania School of Medicine have shown that mutations in two proteins associated with familial Alzheimer's disease disrupt the flow of calcium ions within neurons. The two proteins, called PS1 and PS2 (presenilin 1 and 2), interact with a calcium release channel in an intracellular cell compartment.

Lionfish decimating tropical fish populations, threaten coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.

Massive greenhouse gases may be released as destruction, drying of world wetlands worsens: UN
Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases.

Stem cell chicken and egg debate moves to unlikely arena: the testes
Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.

Predicting acute GVHD by gene expression could improve liver stem cell transplant outcomes
Many cell transplants involve the use of stem cells from another human being (known as an allograft), which raises the major concern of the potential for acute graft-versus-host disease (GVHD).

A viral cloaking device
Viruses achieve their definition of success when they can thrive without killing their host. Now, biologists Pamela Bjorkman and Zhiru Yang of the California Institute of Technology have uncovered how one such virus, prevalent in humans, evolved over time to hide from the immune system.

Coffee and cigarette consumption are high among AA attendees
More than one million Americans currently participate in the Alcoholics Anonymous (AA) program. While AA participants are reportedly notorious for their coffee drinking and cigarette smoking, very little research has quantified their consumption of these two products.

CSHL scientists correlate enzyme expression levels with chemotherapy drug response
Why do cancer patients develop resistance to chemotherapy drugs, sometimes abruptly, after a period in which the drugs seem to be working well to reduce tumors or hold them in check? Although largely a mystery to scientists, the result when this occurs is all too familiar: patients relapse and in many cases die when their cancers become resistant.

Still puzzling: Best care for the frail and elderly with coronary artery disease
A new study from Duke University Medical Center finds that patients treated solely with medications after suffering from chest pain, heart attack or coronary artery disease are more likely to die during the first year following their initial hospitalization.

Water-diffusion technology identifies brain regions damaged by prenatal alcohol exposure
Scientists know that children with Fetal Alcohol Spectrum Disorder (FASD) often have structural brain damage. Yet little is known about how white matter connections, and deep gray matter structures that act as relay stations, are affected in children with FASD.

PCI preference -- will that be an arm or a leg?
When it comes to stenting - using metal tubes to prop open blocked arteries - physicians are continuing to choose to gain entry to the circulatory system through an opening in the leg instead of the arm, even though the latter option appears to be safer, with fewer side effects, say researchers at Duke Clinical Research Institute.
