Sophia Antipolis, France - 29 Aug 2020: More than 90% of babies born with heart defects survive into adulthood. As a result, there are now more adults living with congenital heart disease than children. These adults have a chronic, lifelong condition and the European Society of Cardiology (ESC) has produced advice to give the best chance of a normal life. The guidelines are published online today in European Heart Journal,1 and on the ESC website.2
Sophia Antipolis, France - 29 Aug 2020: Atrial fibrillation is the most common heart rhythm disorder and increases the risk of stroke by fivefold. Patients with irregular heartbeats should choose the treatment plan with their health professionals, according to European Society of Cardiology (ESC) Guidelines published online today in European Heart Journal,1 and on the ESC website.2 The document was developed in collaboration with the European Association of Cardio-Thoracic Surgery (EACTS).
An incredibly rare dinosaur embryo discovered perfectly preserved inside its egg has shown scientists new details of the development and appearance of sauropods which lived 80 million years ago.
Sauropods were the giant herbivores made famous as being 'veggie-saurs' in the 1993 film Jurassic Park. The incredible new find of an intact embryo has shown for the first time that these dinosaurs had stereoscopic vision and a horn on the front of the face which was then lost in adulthood.
Ethylene, a key feedstock in the chemical industry, often includes traces of acetylene contaminants, which need to be removed. In the journal Angewandte Chemie, researchers describe a robust and regenerable porous metal-organic framework that captures acetylene with extraordinary efficiency and selectively. Its synergistic combination of tailor-made pore sizes and chemical docking sites makes the material especially efficient, the study says.
Over the past 20 years or so, the risk for US men and women of suffering from cognitive impairment and dementia has increased. This is the conclusion of a new study by researchers at the Max Planck Institute for Demographic Research (MPIDR) and colleagues that takes into account learning effects when repeating the same dementia test.
Duchenne muscular dystrophy (DMD) is the most common muscle disease in children and is passed on by X-linked recessive inheritance. Characteristic is a progressive muscular atrophy. The disease often results in death before the third decade of life. Researchers of the Universities of Maynooth (Ireland) and Bonn have found a connection between dystrophic muscles and the lymphatic system in mice with Duchenne disease. The results have now been published in the journal iScience.
AMES, Iowa - Nature has worked for eons to perfect surface textures that protect, hide and otherwise help all kinds of creatures survive.
There's the shiny, light-scattering texture of blue morpho butterfly wings, the rough, drag-reducing texture of shark skin and the sticky, yet water-repelling texture of rose petals.
Neighbourhoods with high bikeability and walkability scores actually present higher crash risks to cyclists and pedestrians in Vancouver, according to new research from the University of British Columbia.
A research project on algal blooms along the Swedish coast, caused by eutrophication, revealed that large predators such as perch and pike are also necessary to restrict these blooms. Ecologist Britas Klemens Eriksson from the University of Groningen and his colleagues from Stockholm University and the Swedish University of Agricultural Sciences, Sweden have now shown that stickleback domination moves like a wave through the island archipelagos, changing the ecosystem from predator-dominated to algae-dominated.
The quantum properties underlying crystal formation can be replicated and investigated with the help of ultracold atoms. A team led by Dr. Axel U. J. Lode from the University of Freiburg's Institute of Physics has now described in the journal Physical Review Letters how the use of dipolar atoms enables even the realization and precise measurement of structures that have not yet been observed in any material.
Beginning in May 2020, after the police killing of George Floyd, a Black American man, 'Black Lives Matter' demonstrations and riots engulfed the United States, the United Kingdom, and several European countries. Though Mr. Floyd's killing served as the immediate catalyst for the unrest, many scholars suggest that the COVID-19 pandemic and the resulting economic crisis played a deeper, more pivotal role in creating conditions that led to the protests.
Extremely energy-efficient artificial intelligence is now closer to reality after a study by UCL researchers found a way to improve the accuracy of a brain-inspired computing system.
The system, which uses memristors to create artificial neural networks, is at least 1,000 times more energy efficient than conventional transistor-based AI hardware, but has until now been more prone to error.
MedAxiom, an American College of Cardiology Company and the premier source for cardiovascular organizational performance solutions, has released its eighth annual Cardiovascular Provider Compensation and Production Survey. The report reveals trends across cardiology, surgery, advanced practice providers (APPs) and non-clinical compensation that help cardiovascular organizations as they face a new normal and are reevaluating compensation models and the definition of work productivity.
Key findings include:
DARIEN, IL - Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality.
Hibernation is a familiar feature on Earth today. Many animals -- especially those that live close to or within polar regions -- hibernate to get through the tough winter months when food is scarce, temperatures drop and days are dark.
