Researchers have modelled the fluid dynamics of multi-rotor wind turbines, and how they interact in wind farms. The research demonstrates a clear advantage for a turbine model with four rotors.
With their 220-metre diameter, the wind turbines at the future Dogger Bank wind farm in the North Sea are the world's largest yet. But large, larger, largest is not necessarily the best when it comes to wind turbines.
Hyperbaric oxygen therapy (HBOT) can relieve self-reported symptoms and side-effects of radiotherapy against cancer in the pelvic region, a study shows. After 30-40 sessions in a hyperbaric chamber, many patients experienced reductions in bleeding, urinary incontinence, and pain alike.
"This treatment is highly effective for the majority of the patients" states Nicklas Oscarsson, first author of the article, a doctoral student in anesthesiology and intensive care at Sahlgrenska Academy, University of Gothenburg, and senior consultant at Angered Hospital.
Hostile and competitive people are more likely to give in to drug consumption, according to a study published by a research group at the University of Cordoba (Spain). When a person faces a decision of taking or not taking these kinds of substances, multiple factors come into play, such as social environment, family history and one's own experiences. Now, this research has confirmed that certain personality traits can also be risk factors.
Drug addiction is a vicious cycle of reward and withdrawal. Chronic users often relapse because of the unpleasant physical and psychological symptoms they experience when they stop taking the drug. Now, researchers report in the Journal of Proteome Research metabolic changes in the brains of rats during methamphetamine self-administration and withdrawal that could help identify biomarkers and treatments for addiction.
Energy is information. Lengthening the time during which a system is capable of retaining energy before losing it to the local environment is a key goal for the development of quantum information. This interval is called the "coherence time". Several studies have been performed with the aim of retarding decoherence.
New assistive technology can diagnose collapsed lungs from chest x-rays with a higher degree of accuracy than radiologists.
The system, developed at the University of Waterloo, uses artificial intelligence (AI) software to search a huge database of x-ray images with known diagnoses for comparison to x-rays of new patients with unknown conditions.
That approach enables researchers to identify 75 per cent of cases of collapsed lungs, or pneumothorax. On average, medical specialists diagnose fewer than 50 per cent of cases when chest x-rays are used.
MIT researchers have developed a model that recovers valuable data lost from images and video that have been "collapsed" into lower dimensions.
The model could be used to recreate video from motion-blurred images, or from new types of cameras that capture a person's movement around corners but only as vague one-dimensional lines. While more testing is needed, the researchers think this approach could someday could be used to convert 2D medical images into more informative -- but more expensive -- 3D body scans, which could benefit medical imaging in poorer nations.
A team of engineers and marine biologists built a better suction cup inspired by the mechanism that allows the clingfish to adhere to both smooth and rough surfaces, such as rocks in the area where the tide comes and goes.
PROVIDENCE, R.I. [Brown University] -- A new software system developed by Brown University researchers turns cell phones into augmented reality portals, enabling users to place virtual building blocks, furniture and other objects into real-world backdrops, and use their hands to manipulate those objects as if they were really there.
A University of Wyoming researcher and his team have shown, for the first time, the ability to globally align single-wall carbon nanotubes along a common axis. This discovery can be valuable in many areas of technology, such as electronics, optics, composite materials, nanotechnology and other applications of materials science.
Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate?
An international collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT) in Japan has uncovered a novel virus that may help answer those questions. They published their results online, ahead of print, on July 22 in Infection, Genetics and Evolution, an Elsevier journal.
The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics.
Health experts are increasingly concerned about the rise in medication resistant bacteria.
Flinders University researchers and collaborators in Japan have produced a nanomesh that is capable of delivering drug treatments.
Many of today's scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life data. Providing validation data, using up-to-date methods, was a key motivating factor for a recent experimental study conducted by researchers at the University of Illinois at Urbana-Champaign.
Gone are the days when people use smart speakers -- like Amazon Echo or Google Home -- only as kitchen timers or dinner party music players. These devices have started helping people track their own health, and can even monitor for cardiac arrest.
Now researchers at the University of Washington have developed a new smart speaker skill that lets a device use white noise to both soothe sleeping babies and monitor their breathing and movement.
