Crisis can force re-evaluation and derail efforts to reach goals

Eurekalert - Jun 21 2018 - 00:06
Setbacks are to be expected when pursuing a goal, whether you are trying to lose weight or save money. The challenge is getting back on track and not giving up after a difficulty or crisis, says an Iowa State marketing professor working on practical ways to help people stick to health-related goals.

New study finds US oil & gas methane emissions 60 percent higher than estimated

Eurekalert - Jun 21 2018 - 00:06
The US oil and gas industry emits 13 million metric tons of the potent greenhouse gas methane from its operations each year, 60 percent more than estimated by the US Environmental Protection Agency, according to a new study published today in the journal Science.

Hundreds of thousands of genomes shed light on psychiatric disorders

Eurekalert - Jun 21 2018 - 00:06
A massive undertaking by the Brainstorm Consortium to analyze the genomes of nearly 900,000 people has revealed important insights into the genetic overlap among some psychiatric diseases, as well as among personality traits.

A quick rebound of Antarctic crust promotes ice-sheet stability

Eurekalert - Jun 21 2018 - 00:06
The unexpectedly rapid rebound of the Amundsen Sea Embayment (ASE) may help stabilize the West Antarctic Ice Sheet against catastrophic collapse, says a new study offering a rare silver-lining in glacier research.

US methane emissions greater than thought, in recent years?

Eurekalert - Jun 21 2018 - 00:06
Methane leakage from the US oil and natural gas supply chain is greater than previously estimated, researchers report. US oil and natural gas production has been growing steadily in the last decade.

Northwestern researchers achieve unprecedented control of polymer grids

Eurekalert - Jun 21 2018 - 00:06
The first examples of covalent organic frameworks (COFs) were discovered in 2005, but quality has been poor and preparation methods uncontrolled. Now a Northwestern University research team is the first to produce high-quality versions of these materials, demonstrate their superior properties and control their growth. The team's two-step process produces organic polymers with crystalline, two-dimensional structures. The precision of the material's structure and the empty space its hexagonal pores provide will allow scientists to design new materials with desirable properties.

New research provides expanded insights into the brain's response to opioids

Eurekalert - Jun 21 2018 - 00:06
Opioids are powerful painkillers that act on the brain, but they have a range of harmful side effects including addiction. Researchers from the Max Planck Institute of Biochemistry in collaboration with researchers from the Medical University of Innsbruck, Austria, University of Innsbruck, and the Lewis Katz School of Medicine at Temple University, have developed a tool that gives deeper insights into the brain's response to opioids.

Antarctic ice sheet is melting, but rising bedrock below could slow it down

Eurekalert - Jun 21 2018 - 00:06
An international team of researchers has found that the bedrock below the remote West Antarctic Ice Sheet is rising much more rapidly than previously thought, in response to ongoing ice melt.

Common psychiatric disorders share an overlapping genetic risk

Eurekalert - Jun 21 2018 - 00:06
Investigators found that many common psychiatric disorders are deeply connected on a genetic level, sharing specific genetic risk factors, underscoring the need to recognize shared dimensions of brain dysfunction, and develop new treatment strategies. Results of this investigation have been published in the June 22, 2018 issue of the journal, Science.

Mice not only experience regret, but also learn to avoid it in the future

Eurekalert - Jun 21 2018 - 00:06
New research from the University of Minnesota publishing 21 June in the open access journal PLOS Biology from authors Brian M. Sweis, Mark J. Thomas, and A. David Redish has discovered that mice are capable of learning to plan ahead in order to avoid regret down the road even if there is no additional gain in rewards.

Water can be very dead, electrically speaking

Eurekalert - Jun 21 2018 - 00:06
Water is one of the most fascinating substances on Earth and at the heart of its many unusual properties is high polarizability, a strong response to an applied electric field. Now researchers at the University of Manchester have found that on a microscopic scale water behaves very differently and its thin layers lose any polarizability, becoming electrically dead.

Psychiatric disorders share an underlying genetic basis

Eurekalert - Jun 21 2018 - 00:06
In a new international collaboration, researchers explored the genetic connections between brain disorders at a scale far eclipsing previous work on the subject. The team determined that psychiatric disorders share many genetic variants, while neurological disorders (such as Parkinson's or Alzheimer's) appear more distinct. The results indicate that psychiatric disorders likely have important similarities at a molecular level, which current diagnostic categories do not reflect.

First ancient syphilis genomes decoded

Eurekalert - Jun 21 2018 - 00:06
An international research team has recovered the first historic genomes from the bacterium Treponema pallidum, which causes syphilis. It was previously not thought possible to recover DNA of this bacterium from ancient samples. In the study, published in PLOS Neglected Tropical Diseases, the researchers were able to distinguish genetically between the subspecies of the disease that cause syphilis and that cause yaws, which are not readily distinguishable in skeletal remains.

Changes in a brain signalling system contribute to the development of alcohol addiction-like behaviours in rats, according to a new study led by researchers at Linköping University, Sweden. The findings, to be published in Science, indicate a similar mechanism in humans.

Fast rising bedrock below West Antarctica reveals an extremely fluid Earth mantle

Eurekalert - Jun 21 2018 - 00:06
An international team of researchers, with a new study published in Science with DTU Space as lead author, finds that the bedrock below the West Antarctic Ice Sheet is rising much more rapidly than expected, revealing a very different Earth structure than previously believed. This discovery has important implications in understanding the present and future climate changes in Antarctica.
