If a patient is successfully resuscitated after a cardiac arrest and circulation resumes, they are not out of the woods yet. A number of factors can influence whether and how they survive the trauma in the subsequent phase. The administration of the anaesthetic midazolam has a positive effect, as shown by a multicenter study of 571 patients.
The single-celled organism Naegleria fowleri ranks among the deadliest human parasites. Researchers have now discovered viruses that infect this harmful microbe. Named Naegleriavirus, these belong to the giant viruses, a group known for their unusually large particles and complex genomes.
A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news.
The enzyme PI3K plays a critical role in cell migration. Scientists have long understood this function. But researchers have recently unveiled that a subunit of this enzyme also has the ability to slam on the breaks to this process.
Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
A new study sheds light on how parasites, often overlooked, can dramatically affect the balance between predator and prey populations. Researchers developed a groundbreaking mathematical framework that predicts when predators, prey, and parasites can coexist, considering factors like random fluctuations and parasite effects on both populations. This research provides a valuable tool for conservation by helping predict how parasites influence ecosystem resilience and informing strategies to protect vulnerable species.
Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.
Researchers have developed a deep learning tool that is capable of reliably diagnosing moon blindness in horses based on photos.
As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.
A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.
Researchers have developed a method to determine how reliably target proteins can be labeled using super-resolution fluorescence microscopy.
Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed.
Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.
Scientists demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results show that the air-cloud interface is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds. The research will enable scientists to gain insight into how changes in atmospheric aerosol levels could affect clouds and climate.
A research team has discovered that cancer, one of the leading causes of death worldwide, can be caused entirely by epigenetic changes, in other words, changes that contribute to how gene expression is regulated, and partly explain why, despite an identical genome, an individual develops very different cells (neurons, skin cells, etc.).
Nursing homes in disadvantaged communities are more likely to overmedicate residents with antipsychotics, especially homes that are understaffed, according to a new study.
A multidisciplinary research team has combined ancient DNA data with a clear archaeological, anthropological and historical context to reconstruct the social dynamics of Avar-period steppe descent populations that settled in Europe's Carpathian Basin in the 6th century.
A mystery that has puzzled the scientific community for over 50 years has finally been solved. A team has discovered that a certain type of chemical reaction can explain why organic matter found in rivers and lakes is so resistant to degradation.
The mass production of conventional silicon chips relies on a successful business model with large 'semiconductor fabrication plants' or 'foundries'. New research by shows that this 'foundry' model can also be applied to the field of flexible, thin-film electronics.
Researchers have grown diamonds under conditions of 1 atmosphere pressure and at 1025 degrees Celsius using a liquid metal alloy composed of gallium, iron, nickel, and silicon, thus breaking the existing paradigm. The discovery of this new growth method opens many possibilities for further basic science studies and for scaling up the growth of diamonds in new ways.
