Sept. 5, 2023 – In a new report posted online in the  American Journal of Respiratory and Critical Care Medicine, a global consensus conference of 32 critical care experts with broad international representation and from diverse backgrounds has proposed a new definition of acute respiratory distress syndrome (ARDS). In addition to the experts, critical care societies from around the world provided input,  once they received feedback from their members. The report, which builds on the 2012 Berlin Definition of ARDS, will be published Jan. 1, 2024 in the American Thoracic Society’s AJRCCM. ARDS is a life-threatening illness in which the lungs ...

AMES, IA – During Frito-Lay's first "Crash the Super Bowl" contest in 2006, thousands of participants submitted 30-second videos promoting Doritos. Entries were winnowed down to five finalists, and a public vote selected the winning commercial, which aired during the most watched American television broadcast of the year. The ad boosted Doritos sales and pulled in awards, sparking other big brands, like Nestlé, BMW and Fisher-Price, to launch their own crowdsourcing contests. "Crowdsourcing has become more prevalent over the last decade. It can generate innovative ideas and solutions and engage ...

A new opinion piece published in Health Affairs Forefront raises questions around current approaches to assess drug safety and effectiveness in people with obesity. The article sheds light on how increased body fat can modify the effects of drugs used to treat common conditions, in some cases rendering the drugs ineffective or unsafe for people with obesity. The article, titled “Assessments Of Drug Safety And Effectiveness Continue To Fail People With Obesity,” argues that drug manufacturers should be required to show correct dosing instructions on their labels ...

Over the course of four weeks this summer, a motley crew of biologists, engineers, entrepreneurs and programmers gathered at predetermined sites within Windsor Nature Park, a 185-acre tropical rainforest located in the heart of Singapore. They’d traveled from all over the world to participate in a one-of-a-kind competition hosted by the XPRIZE Foundation, in which 13 teams would have three days to identify as many organisms within the forest as possible. Up to 10 winning teams would equally split $2 million and advance to the 2024 finals, where they’d vie for the first-place prize of $5 million. But there was a catch: All observations and data collection ...

Approximately 95% of the world’s food supply is directly or indirectly produced on soil, according to the Food and Agriculture Organization of the United Nations. Soil health is therefore critical to the health of all living organisms—especially plants. Equally as critical, resources that consider the overlap between soil’s mineral nutrition and plant diseases have been scarce, until members of the American Phytopathological Society (APS) recognized this gap. APS PRESS has newly published an updated edition of the first book to successfully combine the two important plant science disciplines of nutrition and pathology. Mineral Nutrition and Plant Disease, ...

CHAMPAIGN, Ill. — Seven years after an initial $17.9 million award from the National Institutes of Health, the Illinois Kids Development Study at the University of Illinois Urbana-Champaign will receive approximately $13.7 million – awarded in two phases – to continue its work for another seven years. The money coming to Illinois is part of a national collaborative effort to explore how environmental exposures influence child development, cognition, growth and health. IKIDS is part of Environmental Influences on Child Health Outcomes, a national initiative to study five ...

Gratitude is a strong emotion, usually felt by a person who benefits from an intentional good deed of another person. Receiving gifts or benefits can instill a feeling of gratitude in people who receive them, i.e., beneficiaries, encouraging them to be more prosocial, while also helping to create a bond with their benefactors. This has led several researchers to examine the determinants of gratitude. Interestingly, beneficiaries often have preconceived beliefs about receiving a benefit. For instance, they may have no prior expectations of receiving a ...

PULLMAN, Wash. – A more efficient U.S. Postal Service can increase voter turnout in all states regardless of their mail voting laws, according to a Washington State University study. WSU researcher Michael Ritter analyzed election data from 2012 through 2020, when the pandemic encouraged many more people than usual to vote by mail. He found that in general more accessible mail voting laws, such as universal mail-in voting and no-excuse mail voting, increased the probability that individuals would vote. Restrictive laws, such as requiring ...

Organometallic compounds, molecules made up of metal atoms and organic molecules, are often used to accelerate chemical reactions and have played a significant role in advancing the field of chemistry.  Metallocenes, a type of organometallic compound, are known for their versatility and special "sandwich" structure. Their discovery was a significant contribution to the field of organometallic chemistry and led to the awarding of the Nobel Prize in Chemistry in 1973 to the scientists who discovered and explained their sandwich structure.  The ...

Opposites don’t actually attract. That’s the takeaway from a sweeping CU Boulder analysis of more than 130 traits and including millions of couples over more than a century. “Our findings demonstrate that birds of a feather are indeed more likely to flock together,” said first author Tanya Horwitz, a doctoral candidate in the Department of Psychology and Neuroscience and the Institute for Behavioral Genetics (IBG). The study, published Aug. 31 in the journal Nature Human Behaviour, confirms what individual studies have hinted at for decades, defying the age-old adage that “opposites ...

A new study published in IOP Publishing’s journal Environmental Research Letters examines the links between drinking water quality violations and social vulnerability in the United States, revealing that these violations disproportionately affect the most vulnerable communities. Approximately 70% of the population affected ranked in the highest social vulnerability category, with many different social parameters, beyond income, linked to different drinking water quality violations.  The study, led by researchers from the Jackson School of Geosciences, University of Texas in Austin, used new water quality data ...

"Evaluation of the effects of the pandemic and associated measures can provide a historical account and inform health care service planning for both postpandemic recovery and mitigation of potential consequences ...

Peer-reviewed / Empirical study New study challenges political claims that some high-income countries have achieved “green growth”– revealing that under current growth-oriented strategies, emission reductions in these nations fall drastically short of meeting the climate goals and fairness requirements of the Paris Agreement. If current trends continue, even the 11 high-income countries that have "decoupled" carbon emissions from GDP growth would on average take over 200 years to get their emissions close to zero, and would emit more than 27-times their fair share of the “global carbon budget” ...

It seems intuitive that forests would provide better habitat for forest-dwelling wildlife than farms. Yet, in one of the longest-running studies of tropical wildlife populations in the world, Stanford researchers found that over 18 years, smaller farms with varying crop types – interspersed with patches or ribbons of forest – sustain many forest-dependent bird populations in Costa Rica, even as populations decline in forests. In a paper published Sept. 4 in the Proceedings of the National Academy of Sciences, Nicholas Hendershot and colleagues ...

For those fortunate enough to walk normally, wandering is such an expected behavior that we hardly consider that it involves complex, partly involuntary processes. “Animals move to explore their environment in search of food, interaction with others, or simply out of curiosity. But the perception of danger or a painful stimulus can also activate an automatic flight reflex”, Martin Carbo-Tano, a post-doctoral fellow at Paris Brain Institute, explains. In both cases, movement initiation relies on the activation of so-called reticulospinal control neurons, which form an intertwined network in ...

Halle/Saale, Fort Lauderdale. More than 100 years of observations in nature have revealed a universal pattern of species abundances: Most species are rare but not very rare, and only a few species are very common. These so-called global species abundance distributions have become fully unveiled for some well-monitored species groups, such as birds. For other species groups, such as insects, however, the veil remains partially unlifted. These are the findings of an international team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg ...

Extreme El Niño weather saw South America’s forest carbon sink switch off Hot and dry conditions resulted in increased tree death  Evidence that most forest areas withstand periods of severe drought Greatest impact in forests with drier climates  Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research.    For a long time, tropical forests have acted as a carbon sink, taking more ...

When it comes to global warming trends, the Arctic is a troubling outlier. The Arctic warms nearly four times faster than the global average, and aerosols play an important role in that warming. Scientists have long known that pollutants from other regions can accumulate in the Arctic atmosphere where they alter atmospheric chemistry, absorb sunlight, and affect local weather patterns, leading to localized warming that melts ice and snow. Sea salt particles dominate aerosol mass concentration, but their production mechanisms and impact on Arctic climate have remained unclear. Atmospheric scientists led by Jian Wang, director of the Center for Aerosol ...

Around 5.2% of the global population carries abnormal hemoglobin genes [1]. Each year, 300,000 to 500,000 children are born with severe hemoglobinopathies worldwide, with approximately 80% of these cases occurring in developing countries [2]. Thalassemia is the most common hereditary hemoglobinopathy and occurs in 4.4 out of every 10,000 live births [3]. It is prevalent in Mediterranean coastal areas, Africa, the Middle East, Southeast Asia, and southern China. A previous study indicated that Ganzhou, the southernmost city in Jiangxi province, had a thalassemia prevalence ...

Abu Dhabi, UAE (September 4, 2023) – In a breakthrough in cancer therapeutics, a team of researchers at the Magzoub Biophysics Lab at NYU Abu Dhabi (NYUAD) has made a significant advance in light-based therapies – biocompatible and biodegradable tumor-targeting nanospheres that combine tumor detection and monitoring with potent, light-triggered cancer therapy to dramatically increase the efficacy of existing light-based approaches. Non-invasive, light-based therapies, photodynamic therapy (PDT) and photothermal therapy (PTT) have the potential to be safe and effective alternatives to conventional cancer treatments, which are beset by a ...

Traditionally, the impact of human activity on an ecosystem has lacked context when planning restorative ecosystem mitigation and management strategies. Multiple human activities over time and space, the resilience of a particular ecosystem, and the stress caused by many individual or related, overlapping activities that generate cumulative effects may affect the overall "ecosystem response footprint," or ability of an ecosystem to adapt and change to human activity. A team of marine scientists reviewed the most recent perspectives on ecological footprints to rigorously define the term "ecosystem response footprint" as the ...

WEST LAFAYETTE, Ind. – A new cancer therapy developed by Purdue University researchers attacks tumors by tricking cancer cells into absorbing a snippet of RNA that naturally blocks cell division. As reported today in Oncogene, tumors treated with the new therapy did not increase in size over the course of a 21-day study, while untreated tumors tripled in size over the same time period. Cancer can begin almost anywhere in the human body. It is characterized by cells that divide uncontrollably and that may be able to ignore signals to ...
