An analysis conducted by UCLA’s Jody Herman and collaborators at the American Foundation for Suicide Prevention has found that transgender people who experienced rejection by family and friends, discrimination, victimization, or violence have a higher risk for attempting suicide.

Examining data from the National Transgender Discrimination Survey, the researchers found that 78 percent of respondents who suffered physical or sexual violence at school reported suicide attempts, as did 65 percent of respondents who experienced violence at work. (more…)

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.

Risk of Amazon Rainforest Dieback is Higher than IPCC Projects

AUSTIN, Texas — A new study suggests the southern portion of the Amazon rainforest is at a much higher risk of dieback due to stronger seasonal drying than projections made by the climate models used in the latest report by the Intergovernmental Panel on Climate Change (IPCC). If severe enough, the loss of rainforest could cause the release of large volumes of the greenhouse gas carbon dioxide into the atmosphere. It could also disrupt plant and animal communities in one of the regions of highest biodiversity in the world. (more…)

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.

Tiny Capsule Effectively Kills Cancer Cells

Scientists create nanoscale vehicle to battle cancer without harming healthy cells

A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment.
Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.

In a new study, published online Feb. 1 in the peer-reviewed journal Nano Today, a group led by Yi Tang, a professor of chemical and biomolecular engineering and a member of the California NanoSystems Institute at UCLA, reports developing tiny shells composed of a water-soluble polymer that safely deliver a protein complex to the nucleus of cancer cells to induce their death. The shells, which at about 100 nanometers are roughly half the size of the smallest bacterium, degrade harmlessly in non-cancerous cells. (more…)
