Nanotechnology news

	Giant enhancement of magnetic effect will benefit spintronics (Phys.org)—Researchers have demonstrated that coating a cobalt film in graphene doubles the film's perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum multilayers that are being researched for this property. In a material with a high PMA, the magnetization is oriented perpendicular to the interface of the material's layers. High-PMA materials are being researched for their applications in next-generation spintronic devices, such as high-density memories and heat-tolerant logic gates. The researchers, Hongxin Yang, et al., have published a paper on the giant PMA enhancement in a recent issue of Nano Letters.
	3D "nanobridges" formed using electron beam writing with tiny jets of liquid precursor Researchers have demonstrated a new process for rapidly fabricating complex three-dimensional nanostructures from a variety of materials, including metals. The new technique uses nanoelectrospray to provide a continuous supply of liquid precursor, which can include metal ions that are converted to high-purity metal by a focused electron beam.
	Nanotube "forest" in a microfluidic channel may help detect rare proteins and viruses Engineers at MIT have devised a new technique for trapping hard-to-detect molecules, using forests of carbon nanotubes.

Those who commute home after working the night shift may be at high risk for drowsy driving crashes because of disruption to their sleep-wake cycles and insufficient sleep during the night.
Study finds that more than one-third of patients with metastatic cancer continue to work A new analysis indicates that many patients continue working after being diagnosed with metastatic cancer, but a heavy burden of symptoms may prevent them from doing so. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study illustrates the need to treat difficult symptoms so that patients can maintain their employment.
	Biochemical clues may predict who develops Alzheimer's disease—and who doesn't Investigators have wondered why the brains of some cognitively-intact elderly individuals have abundant pathology on autopsy or significant amyloid deposition on neuroimaging that are characteristic of Alzheimer disease (AD). Researchers reporting in The American Journal of Pathology investigated biochemical factors and identified differences in proteins from parietal cortex synapses between patients with and those without manifestation of dementia. Specifically, early-stage AD patients had elevated concentrations of synaptic soluble amyloid-β (Aβ) oligomers compared to controls who were not demented but displayed signs of AD pathology. Synapse-associated hyperphosphorylated tau (p-tau) levels did not increase until late-stage AD.

	Candy games stimulate appetite At least once a week, two thirds of all children of primary-school age will play an internet game that was created to draw attention to a brand. Most of these advertisements are for snacks and candy. Only 6% of these children are aware that such advergames are advertisements. In the meantime, such games do affect their behaviour, discovered Frans Folkvord, and if it were up to him they would be banned. Folkvord, a behavioural scientist at Radboud University, will be awarded a PhD for his work on 13 January 2016.
	Protein that boosts memory identified Increasing the level of a certain DNA-modified enzyme in the brain significantly improves cognitive ability. The discovery was made by the research team led by Prof. Dr. Hilmar Bading at the Interdisciplinary Center for Neurosciences of Heidelberg University. Mouse experiments showed that the Dnmt3a2 protein can boost memory performance in the animals. Because this protein also affects fear memory and the ability to erase bad memories, the researchers hope these findings can be used to develop new treatments for post-traumatic stress disorder and other forms of anxiety. The results of the research were published in the journal Molecular Psychiatry.

	Reduction of contrast medium volume and radiation dose in CTA scans Wouter Nijhof obtained his PhD at the University of Twente for the research he conducted in collaboration with the Radiology department at the Jeroen Bosch Hospital in 's-Hertogenbosch. The results of his PhD thesis can almost directly be applied in nearly every hospital. Dr Nijhof showed that a CTA scan (a scan of the arteries) can be performed with a contrast medium volume reduction of up to 75% and up to 50% reduction in radiation dose. CT scans using contrast medium are the third most common cause of acute renal failure and renal insufficiency as a result of hospital treatments. The health benefits that Nijhof's research can bring are therefore enormous.

Researchers find heart attack patients not always receiving lowest-risk care More than 375,000 American each year experience a heart attack, during which blood flow to a part of the heart is impeded by blocked arteries. Physicians often treat patients with stents, which prop open the arteries to allow blood to flow again. They use two approaches to place stents: transradial, or entry of the catheter which delivers the stent through the wrist, or transfemoral, in which the catheter is placed through the groin. In a comparison of bleeding complications and mortality between the two approaches, researchers from the Perelman School of Medicine at the University of Pennsylvania found that those at risk for more bleeding were often treated with a riskier procedure - the transfemoral approach - a demonstration of the so-called risk-treatment paradox. The findings, from the largest study of its kind, are detailed in this week's Journal of the American College of Cardiology: Cardiovascular Interventions.
