U.S. teens who are food insecure are more likely to engage in emotional eating and consume sugar-sweetened beverages and junk foods

Coccolithophores, a globally ubiquitous type of phytoplankton, play an essential role in the cycling of carbon between the ocean and atmosphere. New research from Bigelow Laboratory for Ocean Sciences shows that these vital microbes can survive in low-light conditions by taking up dissolved organic forms of carbon, forcing researchers to reconsider the processes that drive carbon cycling in the ocean. The findings were published this week in Science Advances. The ability to extract carbon from the direct absorption of dissolved organic carbon is known as osmotrophy. ...

Plastic pollution is seemingly omnipresent in society, and while plastic bags, cups, and bottles may first come to mind, plastics are also increasingly used to make clothing, rugs, and other textiles.  A new study from UC San Diego’s Scripps Institution of Oceanography, published May 24 in the journal PLOS One, for the first time tracked the ability of natural, synthetic, and blended fabrics to biodegrade directly in the ocean.  Lead author Sarah-Jeanne Royer conducted an experiment off the Ellen Browning Scripps Memorial Pier and found that natural and wood-based cellulose fabrics degraded within a month. Synthetic textiles, including so-called compostable ...

Rising temperatures due to climate change are likely influencing human migration patterns, according to a new study by Rita Issa of University College London and colleagues, published May 24 in the open-access journal PLOS Climate. In the last decade, heatwaves were frequent, and surface temperatures were the warmest on record. As the planet warms, many people are expected to leave their homes to escape extreme temperatures. However, the exact role of heat in human migration is not yet understood. To illuminate this relationship, Issa’s team conducted a review of research documents, ...

The epidemic of firearm injury and death in the USA is preventable, and the field of public health can offer practical solutions, argue Dr. Megan L. Ranney and colleagues in an opinion article in PLOS Global Public Health. Through harm reduction and community engagement programs, public health professionals, healthcare providers and community members can reduce the impact on individuals, families and communities. Despite the attention school and public mass shootings in the US gain, they make up a minority of US firearm injuries and deaths. Most firearm deaths are from homicide and suicide: ...

Political parties regularly claim to have their finger on the pulse and be able to read the public mood. Yet a new study challenges the idea that being political makes you good at understanding others: it shows gender, not politics, is a far more important factor in determining people’s social skills. Analysis of a sample of 4,000 people from across the UK, compiled by a team of psychologists at the University of Bath, highlights that being female and educated are the biggest determinants of whether you can understand or read others’ ...

The prevalence of sleep disorders, like sleep apnea, is on the rise in the U.S., but current protocols to conduct clinically accepted assessments are expensive and inconvenient. Georgia Tech researchers have created a wearable device to accurately measure obstructive sleep apnea — when the body repeatedly stops and restarts breathing for a period — as well as the quality of sleep people get when they are at rest. Under conventional methods, people who are suspected of having some sleep issue or disorder ...

To know when it’s time for a meal – and when to stop eating again – is important to survive and to stay healthy, for humans and animals alike. Researchers at the Max Planck Institute for Biological Intelligence investigated how the brain regulates feeding behavior in mice. The team found that the hormone ghrelin activates specialized nerve cells in a brain region known as the amygdala. Here, the interaction between ghrelin and the specialized neurons promotes food consumption and conveys ...

A team of researchers at the University of Houston College of Pharmacy is reporting that by manipulating TAK1, a signaling protein that plays an important role in development of the immune system, they can slow down disease progression and improve muscle function in Duchenne muscular dystrophy (DMD).  DMD, caused by mutations in dystrophin gene, is an inheritable neuromuscular disorder that occurs in one out of 3,600 male births. DMD patients undergo severe muscle wasting, inability to walk and eventually death in their early thirties due to respiratory failure. The ...

Research question Can these contributions to standing postural control be quantified from CoP trajectories in neurotypical adults? Methods Instantaneous contributions can be negative or larger than one, and integrated contributions sum to equal one. Proof-of-concept demonstrations validated these calculated contributions by restricting CoP motion under one or both feet. We evaluated these contributions in 30 neurotypical young adults who completed two (eyes opened; eyes closed) 30-s trials of bipedal standing. We evaluated the relationships between limb contributions, self-reported limb dominance, and between-limb ...

A University of Texas at Arlington civil engineering researcher will use a NASA grant to help forecasters better predict extreme weather events using a variety of existing NASA data sources. Yu Zhang, associate professor in the Department of Civil Engineering, said the $638,000 grant will use ocean circulation data, atmospheric conditions and current weather information to make longer-range forecasting more reliable. Having a more accurate forecast could help officials make better decisions about the state’s water resources—for example, knowing when to release water from reservoirs. “Using ...
