People who became pregnant using assisted reproductive technologies were found to be over twice as likely to develop preeclampsia than those with traditional pregnancies, according to a study presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology. The study, based on an analysis of health records from over 2.2 million patients, is the first to assess how reproductive technologies may affect the risk of cardiovascular complications during pregnancy on a national scale. Preeclampsia is a pregnancy-related complication involving new onset high ...

People who used marijuana daily were found to be about one-third more likely to develop coronary artery disease (CAD) compared with people who have never used the drug, according to a study presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology.        As cannabis becomes legal in an increasing number of U.S. states, this study is among the largest and most comprehensive to date to examine the potential long-term cardiovascular implications of using the drug. CAD is the most common form of heart disease and occurs when the arteries that supply blood to the heart ...

People with Type 2 diabetes who were given a smartphone app that delivers personalized cognitive behavioral therapy (CBT) saw significantly greater reductions in their blood sugar and less need for higher doses of diabetes medications at six months compared with those who only received standard diabetes care and a control app, in a study presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology. A clear “dose effect” was seen, with patients completing more CBT lessons seeing the greatest benefits. “When studied in a large randomized controlled ...

More than 100 years ago, Charles Doolittle Walcott from the Smithsonian Institution was asked to examine strange star-shaped fossils with lobes hailing from the ~ 514-million-year-old Conasauga Formation in Alabama. Walcott described these odd fossils as jellyfish that likely floated in the middle Cambrian seas of what is now the southeastern United States. Little did he know that the Cambrian fossil he named would cause over 100 years of controversy. The controversy hinged on the interpretation of what Brooksella really was: Was it truly a jellyfish ...

The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons. What happens ...

University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression as a new study shows that physical activity is 1.5 times more effective than counselling or the leading medications.   Published in the British Journal of Sports Medicine, the review is the most comprehensive to date, encompassing 97 reviews, 1039 trials and 128,119 participants. It shows that physical activity is extremely beneficial for improving symptoms of depression, anxiety, and distress.   Specifically, the review showed that exercise interventions ...

It takes a few moments for the sound of thunder to reach our ears after a flash of lightning. This phenomenon is due to the photoacoustic (PA) effect where materials near the lightning instantly expand as the optical energy of the lightning is absorbed and converted into thermal energy. Using this PA effect, photoacoustic computed tomography (PACT) has become a premier preclinical and clinical imaging modality to take images inside the body without using a contrast medium. However, its low-quality images, which can be improved with multiple ultrasound sensors and a multi-channel data acquisition (DAQ) system, ...

· Diseased neurons have pathology in which proteins become misfolded and toxic · Normally supportive cells attack the diseased neurons and destroy them · This pathology occurs in 90% of ALS patient brains and in frontotemporal dementia and Alzheimer’s disease CHICAGO --- Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, ...

Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021. Lead author Adjunct Professor Fred Wells, from Curtin’s School of Molecular and Life Sciences, said the west end of Rottnest Island had suffered a “catastrophic decline” in biodiversity. “Since 1982, we have monitored biodiversity of marine molluscs and echinoderms ...

This study is led by Dr. Shaowei Chen (University of California). Natural gas reforming accounts for 95% of the hydrogen gas produced in the United States; yet the hydrogen is non-sustainable and “grey”, as it originates from fossil fuels . To obtain sustainable “green” hydrogen gas, electrochemical water splitting by using renewable electricity has emerged as one of the most promising technologies, which consists of hydrogen evolution reaction (HER) at the cathode and oxygen evolution reaction (OER) at the anode . Yet, due to the sluggish electron-transfer kinetics and complex reaction pathways, OER typically entails a large overpotential and severely ...

By Alistair Jones SMU Office of Research & Tech Transfer – Despite hero moments in movies where fingers clatter at dizzying speed across computer keyboards, not everyone in the real world finds code fascinating, nor algorithms intriguing. In fact, there is a worldwide shortage of skilled data scientists and software engineers. David Lo, a Professor of Computer Science at Singapore Management University (SMU), suggests two reasons for the shortfall. “First, software today is everywhere; organisations, companies, governments ...

An analysis of fossils of non-avialan theropod dinosaurs – a dinosaur clade that includes an array of body sizes – has provided findings that run contrary to expectations regarding the factors that inform the evolution of body size diversity. “Once quantified and analyzed in a phylogenetic framework [like this], we predict that diverse growth strategies will be recognized in other clades,” say the study’s authors. Over evolutionary history, many taxa have evolved very large and very small body sizes, and even closely related species can exhibit widely disparate sizes. ...

In the UK, disparities in mortality risk factors exist between ethnic groups, with differences in overall mortality, top causes of mortality and individual mortality risk factors, according to a new study published this week in the open-access journal PLOS Global Public Health by I. King Jordan of Georgia Institute of Technology, US, and colleagues. Despite the progress made in improving mortality rate, life expectancy, and disease survival outcomes in the last century, health disparities between various population ...

RICHLAND, Wash.—There’s a lot of potentially useful raw materials bound up in used face masks, grocery bags and food wrap. But it has been much cheaper to keep making more of these single-use plastics than to recover and recycle them. Now, an international research team led by the Department of Energy’s Pacific Northwest National Laboratory has cracked the code that stymied previous attempts to break down these persistent plastics. They reported their discovery in today’s issue of Science. Low temperature and reaction control Typically, recycling plastics requires ‘cracking’ or ...

The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found – to their surprise– that smaller and larger theropod dinosaurs like these didn’t necessarily get that way merely by growing slower or faster. In a new paper published in Science, “Developmental strategies underlying gigantism and miniaturization ...

High-resolution microscopy techniques, for example electron microscopy or super-resolution microscopy, produce huge amounts of data. The visualization, analysis and dissemination of such large imaging data sets poses significant challenges. Now, these tasks can be carried out using MoBIE, which stands for Multimodal Big Image Data Exploration, a new user-friendly, freely available tool developed by researchers from the University of Göttingen and EMBL Heidelberg. This means that researchers such as biologists, who rely ...
