Arctic study shows key marine food web species at risk from increasing CO2

A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival if ocean acidity continues to rise.

The study found that copepods that move large distances, migrating vertically across a wide range of pH conditions, have a better chance of surviving.

The increasing level of carbon dioxide in our atmosphere is changing ocean chemistry leading to seawater moving down the pH scale towards acidity. Some areas of the Arctic Ocean are already experiencing the fastest rates of acidification on the planet and, combined with sea-ice loss and warming temperatures, the impacts of climate change are likely to hit Arctic marine life first.

A large, newly published study that includes more than 13,500 postmenopausal women has yielded the most definitive associations yet between certain lifestyle and demographic factors and levels of a promising early biomarker of type 2 diabetes risk.

PROVIDENCE, R.I. [Brown University] — Over the last decade researchers have amassed increasing evidence that relatively low levels of a protein called sex hormone binding globulin (SHBG) can indicate an elevated risk of type 2 diabetes and metabolic syndrome years in advance. (more…)

Sea level rise: New iceberg theory points to areas at risk of rapid disintegration

ANN ARBOR — In events that could exacerbate sea level rise over the coming decades, stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean, according to new iceberg calving simulations from the University of Michigan.

“If this starts to happen and we’re right, we might be closer to the higher end of sea level rise estimates for the next 100 years,” said Jeremy Bassis, assistant professor of atmospheric, oceanic and space sciences at the U-M College of Engineering, and first author of a paper on the new model published in the current issue of Nature Geoscience.

Genomic Detectives Crack the Case of the Missing Heritability

Despite years of research, the genetic factors behind many human diseases and characteristics remain unknown. The inability to find the complete genetic causes of family traits such as height or the risk of type 2 diabetes has been called the “missing heritability” problem.

A new study by Princeton University researchers, however, suggests that missing heritability may not be missing after all — at least not in yeast cells, which the researchers used as a model for studying the problem. Published in the journal Nature, the results suggest that heritability in humans may be hidden due only to the limitations of modern research tools, but could be discovered if scientists know where (and how) to look.

Technique may lead to earlier diagnosis, tracking of brain disorders in athletes

Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage they can cause becomes increasingly evident among both current and former athletes. The Centers for Disease Control and Prevention estimates that millions of these injuries occur each year.

Despite the devastating consequences of traumatic brain injury and the large number of athletes playing contact sports who are at risk, no method has been developed for early detection or tracking of the brain pathology associated with these injuries. (more…)

Syria Policy Warning over Weapons of Mass Destruction Risk

Policy-makers have been warned that premature military action in Syria could lead to uncontrolled access to weapons of mass destruction and a prolonged, bitter insurgency following any intervention that resulted in the sudden collapse of the Syrian security forces.

Despite the desire to prevent further bloodshed, taking direct action to try to end the conflict could be the “worst option” and could only serve to further destabilise the situation in the volatile country.

General (Retd) Professor Sir Paul Newton co-wrote the report alongside distinguished Middle Eastern scholars at the University of Exeter’s Strategy and Security Institute, of which he is Director. He said: “Although it may appear attractive in the short-term, the one scenario that must be avoided is sudden, uncontrolled state collapse. This may seem like a paradox given the pressing need to end humanitarian suffering and the risk of the conflict spreading. However, it could be catastrophic. If unmanaged disintegration of the Syrian state were to occur, access to weapons of mass destruction would be uncontrolled.” (more…)

People who worry constantly are at greater risk for post-traumatic stress disorder, according to new Michigan State University research published in the journal Psychological Medicine.

Many people experience traumatic events such as the death of a loved one, being assaulted or witnessing violence, but only a small minority develop PTSD, said study author Naomi Breslau, a professor of epidemiology at MSU. (more…)
