A new type of computer memory which could solve the digital technology energy crisis has been invented and patented by scientists from Lancaster University in the UK.
The electronic memory device - described in research published in Scientific Reports - promises to transform daily life with its ultra-low energy consumption.
In the home, energy savings from efficient lighting and appliances have been completely wiped out by increased use of computers and gadgets, and by 2025 a 'tsunami of data' is expected to consume a fifth of global electricity.
WASHINGTON -- One of the largest studies on out-of-pocket costs for nursing home care finds prices are high and rising faster than other medical care and consumer prices, reports a team of health policy researchers.
Their study, published in Medical Care Research and Review, reviews nursing home prices in eight states between 2005-2010 and uncovers out-of-pocket prices that increase significantly beyond normal inflation and inflation in medical care prices.
WEST LAFAYETTE, Ind. - The United States is seeing an increase in the number of neurological diseases. Stroke is ranked as the fifth leading cause of death, with Alzheimer's being ranked sixth. Another neurological disease - Parkinson's - affects nearly 1 million people in the U.S. each year.
Implantable neurostimulation devices are a common way to treat some of these diseases. One of the most commonly used elements in these devices is platinum microelectrodes - but it is prone to corrosion, which can reduce the functional lifetime of the devices.
If the climate continues warming as predicted, spruce beetle outbreaks in the Rocky Mountains could become more frequent, a new multi-year study led by Colorado State University finds.
Physicists discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.
New research shows an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. Even by the end of the century, the island could lose 4.5% of its ice, contributing up to 13 inches of sea level rise.
Engineers have shown it is technically possible to guide a tiny robotic capsule inside the colon to take micro-ultrasound images.
Known as a Sonopill, the device could one day replace the need for patients to undergo an endoscopic examination, where a semi-rigid scope is passed into the bowel - an invasive procedure that can be painful.
Micro-ultrasound images also have the advantage of being better able to identify some types of cell change associated with cancer.
The prosthetics technology is based on potato and corn materials which serve as "food" for the replaced tissues and can be slowly absorbed by the patient's own tissue. If the trials are successful, the treatment can be used for sclerosis, aneurysms, and various blood vessel pathologies.
Scientific inquiry often begins with the "why."
Without expecting to do more than answer a question posed by a YouTube video, Virginia Tech researchers may have changed how people think about the process of freezing.

Electric cars struggle with extreme temperatures, mainly because of impacts on the electrolyte solutions in their lithium-ion batteries. Now, researchers have developed new electrolytes containing multiple additives that work better over a wide temperature range. They report their results in ACS Applied Materials & Interfaces.
We marvel at flying animals because it seems like they can access anywhere, but a first study of its kind has revealed that wind can prevent seabirds from accessing the most important of habitats: their nests.
If human pilots or animals are to land safely, they must monitor and respond to the wind. These ideas are well established in aeronautical engineering, but how the win affects the ability of birds to land has never been considered before.
PITTSBURGH--Computer vision researchers have demonstrated they can use special light sources and sensors to see around corners or through gauzy filters, enabling them to reconstruct the shapes of unseen objects.
The researchers from Carnegie Mellon University, the University of Toronto and University College London said this technique enables them to reconstruct images in great detail, including the relief of George Washington's profile on a U.S. quarter.
New Rochelle, NY, June 19, 2019-Surfaces that enable endothelial cell attachment without causing blood clotting are needed for various tissue engineering efforts. A new approach involving phage display has been used to identify unique peptides with these typically divergent characteristics. The work is published in Tissue Engineering, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. Click here to read it for free through July 20, 2019.
EAST LANSING, Mich. - While previous research has suggested a link between low levels of vitamin D in the blood and an increased risk of cardiovascular disease, a new Michigan State University study has found that taking vitamin D supplements did not reduce that risk.
The large-scale study, published in the Journal of the American Medical Association Cardiology, found that vitamin D supplements did not decrease the incidence of heart attacks, strokes or other major adverse cardiovascular events.
COLUMBUS, Ohio - Researchers were surprised to find that a migratory songbird that breeds in the eastern and central United States is concentrated during winter in just one South American country.
The study found that 91 percent of 34 Prothonotary Warblers fitted with tracking technology at six U.S. breeding sites spent their winter in northern Colombia - an area just 20 percent the size of their breeding range.
