Umbrella-shaped diamond nanostructures make efficient photon collectors

Standard umbrellas come out when the sky turns dark, but in the nanoworld, umbrella shapes may be the next creative way to enhance light emission. Inspired by recent work to enhance the luminescence from diamond nanopillar structures, a team of researchers in Japan has discovered that "umbrella-shaped" diamond nanostructures with metal mirrors on the bottom are more efficient photon collectors than their diamond nanostructure "cousins" of other shapes.

A 'hot' new development for ultracold magnetic sensors

Magnetoencephalography, or MEG, is a non-invasive technique for investigating human brain activity for surgical planning or research, and has been used in hospitals and universities for more than 30 years. It's just one of the many powerful technologies made possible by a tiny device called a SQUID, short for superconducting quantum interference device. SQUIDs can detect minuscule magnetic fields, useful in applications ranging from medical imaging of soft tissue to oil prospecting.

Scientists gain insight into origin of tungsten-ditelluride's magnetoresistance

Scientists recently discovered that tungsten ditelluride (WTe2) is electronically three-dimensional with a low anisotropy. Anisotropy reflects the change in properties of a material when the direction of the current or the applied magnetic field is varied.

Internal fingerprint sensor peers inside fingertips for more surefire ID

In the 1971 film Diamonds are Forever, British secret agent James Bond uses fake fingerprints as part of a ploy to assume the identity of a diamond smuggler. At the time, sham prints were purely a futuristic bit of Bond gadgetry, but technology has since caught up.

Tiny dancers: Can ballet bugs help us build better robots?

When it's time to design new robots, sometimes the best inspiration can come from Mother Nature. Take, for example, her creepy, but incredibly athletic spider crickets.

New equation bolsters multiphase modeling code

While designing models for the Multiphase Flow with Interphase Exchanges (MFiX) code, one of the National Energy Technology Laboratory's most robust computational tools, Physical Research Scientist Jordan Musser realized that an important component of energy system behavior was not accurately accounted for in the existing code. In energy systems, it is common for more than one phase of matter to interact with another, a phenomenon known as multiphase flow. For instance, during combustion and gasification, coal particles interact with gases, creating a gas-solid.

Making the (reactive) case for explosives science

A "reactive case" is a new concept in explosives science currently being tested at Los Alamos National Laboratory. A reactive case would do more than just contain an explosive, but rather become part of the explosive event itself, actually enhancing or boosting the explosion while decreasing far-field fragmentation damage. Advancing fundamental explosives science by testing entirely new ideas like this is a key component of the Laboratory's national security mission.

Formation of coastal sea ice in North Pacific drives ocean circulation and climate

An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing climate on regional and global scales. Coastal sea ice formation takes place on relatively small scales, however, and is not captured well in global climate models, according to scientists at the University of California, Santa Cruz, who conducted the study.

Study implicates global warming as a factor in increasing economic losses due to hurricanes

(Phys.org)—A trio of researchers affiliated with Universidad Nacional Autónoma in Mexico, and VU University in the Netherlands, has conducted a study on the source of an increase in property dollar amounts lost over the past several decades due to hurricanes and has concluded that it cannot be blamed on an increase in wealth or construction—instead, they suggest in their paper published in Nature Geoscience, that it is due to more storms, because of global warming. Stéphane Hallegatte with the Climate Change Policy Team at the World Bank, offers a News & Views piece in the same journal edition on the work done by the team, outlining the process that was used, and highlighting possible problems with the results.

From good to bad with a copper switch

At the molecular level, the difference between Doctor Jekyll and Mr Hyde lies in a metal, copper. In its physiological form, the prion protein (PrPC ) is 'good' and is involved in normal body processes. It can happen, however, that because of some as yet unknown mechanism, it changes form and turns into a threat for the health of humans and animals (it is responsible for neurodegenerative diseases such as spongiform encephalopathies). According to a new SISSA study, the mechanism underlying this change is a metal, copper, or rather a particular region of the protein to which the metal binds, which acts as a sort of 'switch' that turns PrPC into its terrible alter ego.

New dental tool creates stronger bonds for fillings

Establishment of enhancer landscapes in hematopoietic cells revisited

A study from Patrick Matthias and his group at the FMI challenges a widely accepted model on how epigenome dynamics control the differentiation of hematopoietic cells. The plasticity of pluripotent stem cells was thought to be written in their genome in the form of a reduced heterochromatin prevalence and an abundance of "primed" regulatory regions (promoters and enhancers), from which the active elements to be used in later developmental stages are selected. Here, the authors show that early priming of enhancers and heterochromatin dynamics only play a minor role and that most active enhancers are generated de novo without involvement of these mechanisms. The study thus provides important novel insights into the dynamic regulation of the epigenome during hematopoiesis and possibly other systems.

Is nutrition the future of brain health?

We take it for granted that our body can regenerate cells that become injured or simply wear out and die. For most of the 20th century, however, scientists were convinced that one organ—the brain—lacked that ability. Shortly after birth, they thought, our brains had as many neurons as they were ever going to have, and if we lost brain cells because of injury or aging, we were never going to make more of them.

Opinion: You can't be 'a little bit OCD' but your everyday obsessions can help end the stigma

"I'm a little bit OCD" is a phrase that's often bandied around. Perhaps you've used it to describe your excessive cleaning habits or desire for order. Some argue that the flippant use of this phrase trivialises a serious condition and increases stigma. It certainly doesn't help our understanding of the problem. But denying the obsessive-compulsive experiences that we all have may actually be increasing stigma and preventing those who are suffering from seeking help.

New study explains why you bulk up with resistance training, not endurance training

Resistance and endurance exercises affect the body very differently. These differences suggest that adapting to exercise involves many processes, but scientists have observed that one gene in particular, peroxisome proliferator-activated receptor-gamma coactivator PGC-1α, controls many of them. New research in Physiological Reports shows that although both resistance and endurance exercises activate the PGC-1α gene, the adaptation processes stimulated are not the same and depend on the type of exercise.

Different memory resolutions map onto different brain locations

Neuroscientists from Radboud University's Donders Institute have shown that memories of the same events co-exist at different resolutions in the brain. Coarse and fine memory scales are distributed across different parts of the hippocampus, a brain area that plays an important part in memory. Nature Neuroscience publishes the results on October 19.

Bangladesh health successes shift chronic diseases to poor

A new study published in the International Journal of Epidemiology shows that over the past decades Bangladesh observed a successful health transition while chronic diseases shifted from the rich to affect in excess also poor households. Observations over more than two decades demonstrate that the situation is actually worsening as chronic diseases frequently drag more households below the poverty line. The challenges in health service delivery and financing are huge.

Transfusion with stored blood safe in heart surgery

A large registry study led from Sweden's Karolinska Institutet shed new light on the much debated issue of transfusions with stored blood. The study, which is published in the journal JAMA, shows that the use of stored blood units does not influence patient outcomes after heart surgery.

Annual vs. biennial mammography and breast tumor prognostic characteristics

Premenopausal women diagnosed with breast cancer following a biennial screening mammogram were more likely to have bigger more advanced tumors than women screened annually, while postmenopausal women not using hormone therapy had a similar proportion of tumors with less favorable prognostic characteristics regardless of whether their screening mammogram was biennial or annual, according to an article published online by JAMA Oncology.

Later age recommended for first screening mammogram

Among the changes in the American Cancer Society's updated breast cancer screening guideline is that women with an average risk of breast cancer should undergo regular, annual screening mammography beginning at age 45 years, with women having an opportunity to choose to begin annual screening as early as age 40; women 55 years and older should transition to screening every other year (vs annual), but still have the opportunity to continue with annual screening; and routine screening clinical breast examination is no longer recommended, according to an article in the October 20 issue of JAMA.

A new way to starve lung cancer?

Scientists have identified a new way to stop the growth of lung cancer cells, by blocking their ability to use alternative sources of nutrition. The discovery was made possible by identifying the metabolic programs used by cancer cells to fuel their growth. The findings point to possible new avenues for treating lung cancer, which is the second most common cancer and accounts for over one-quarter of all cancer-related deaths. The results of the study were published Oct. 15 in the journal Molecular Cell.

Preeclampsia associated with increased risk of heart defects in infants

An analysis of more than 1.9 million mother and infant pairs finds that preeclampsia was significantly associated with noncritical heart defects in offspring, and preeclampsia with onset before 34 weeks was associated with critical heart defects; however, the absolute risk of congenital heart defects was low, according to a study in the October 20 issue of JAMA.

Muscle relaxant or opioid combined with NSAID does not improve low back pain

Among patients with acute, low back pain presenting to an emergency department, neither the nonsteroidal anti-inflammatory drug (NSAID) naproxen combined with oxycodone/acetaminophen or the muscle relaxant cyclobenzaprine provided better pain relief or improvement in functional outcomes than naproxen combined with placebo, according to a study in the October 20 issue of JAMA.

Tdap vaccination during pregnancy following other recent tetanus-containing vaccine

Among women who received the tetanus, diphtheria, and acellular pertussis (Tdap) vaccine during pregnancy, there was no increased risk of adverse events in the mothers or adverse birth outcomes in newborns for women who had received a tetanus-containing vaccine in the previous 5 years, according to a study in the October 20 issue of JAMA.

Effect of duration of storage of red blood cells transfused for cardiac surgery

Although some studies have suggested that transfusion of stored red blood cell (RBC) concentrates may be harmful, as blood undergoes several physiological changes during storage, an analysis of patients who underwent cardiac surgery in Sweden over a 16-year period found no association between duration of RBC storage and risk of death or serious complications, according to a study in the October 20 issue of JAMA.

Inherent mindfulness linked to lower obesity risk, belly fat

Their findings, published in Neurosurgery, lend hope to patients around the world with neurological conditions that are difficult to treat due to a barrier mechanism that prevents approximately 98 percent of drugs from reaching the brain and central nervous system.

Researcher develops vaccine for fatal disease

Over 200 million people in 74 countries suffer from schistosomiasis and four times that many are at risk for the disease since they do not have access to clean water. A recent discovery in the Texas Tech University Health Sciences Center (TTUHSC) research laboratory may make it possible to reduce the number of infections from this disease.

Mechanism identified for enhancing immunological memory in helper T cells

Vaccines help prevent disease by inducing immunological memory, the ability of immune cells to remember and respond more quickly when re-exposed to the same pathogen. While certain phases of the pathway are well understood, little is known about the role of helper T cells, a "master orchestrator" of the immune response that send signals to activate the immune system.

'Big Data' used to identify new cancer driver genes

In a collaborative study led by Sanford Burnham Prebys Medical Discovery Institute (SBP), researchers have combined two publicly available 'omics' databases to create a new catalogue of 'cancer drivers'. Cancer drivers are genes that when altered, are responsible for cancer progression. The researchers used cancer mutation and protein structure databases to identify mutations in patient tumors that alter normal protein-protein interaction (PPI) interfaces. The study, published today in PLoS Computational Biology, identified more than 100 novel cancer driver genes and helps explain how tumors driven by the same gene may lead to different patient outcomes.

Team combats memory loss by enhancing brain function

A new study, led by scientists at The Scripps Research Institute (TSRI), the Veterans Affairs San Diego Healthcare System (VA) and University of California (UC) San Diego School of Medicine shows that increasing a crucial cholesterol-binding membrane protein in nerve cells (neurons) within the brain can improve learning and memory in aged mice.

Does living in the United States promote teenage risk taking?

Teenagers are known for taking unnecessary risks, from reckless driving to smoking marijuana, but some seek out risky experiences more than others. A new study of sensation-seeking behavior led by a researcher at Columbia University's Mailman School of Public Health with colleagues from Columbia University's Department of Psychiatry and the University of Puerto Rico School of Medicine, shows that children growing up in the United States versus Puerto Rico were more likely to seek out new and risky behaviors. Results of the study, the first to look at sensation-seeking patterns in young children and teenagers, are published online in the Journal of the American Academy of Child and Adolescent Psychiatry.

Research study validates neuroreader for accurate and fast measurement of brain volumes

A new neuroimaging software, Neuroreader, was shown to be as accurate as traditional methods for detecting the slightest changes in brain volume, and does so in a fraction of the time, according to a research study published in the Journal of Alzheimer's Disease this month. The research validates the software program that can be used for measuring hippocampal volume, a biomarker for detecting Alzheimer's Disease.

Researchers find AKI a predictor of higher mortality rates for stroke patients

A University of Cincinnati (UC) researcher, in collaboration with other investigators, has found that ischemic and hemorrhagic stroke patients who suffer from acute kidney injury (AKI) requiring dialysis have higher death rates and greater odds of entering long-term care or nursing facilities after hospitalization.

Stimulating specific brain area could help defrost arms frozen by stroke

Little can be done to help the hundreds of thousands of people whose severe strokes have left them with one arm stuck close to the sides of their bodies like a broken wing. A 30-patient study by Washington researchers, however, has found that magnetically stimulating a specific part of their brains can affect arm movements—raising hope that, in the future, a short course of therapy targeting this area could help to free the arm and restore some use of the stroke-affected limb.

Understanding the activation of BAT for improved diabetes treatment

Research into diabetes and obesity has made some huge strides in recent years. And one of the most promising findings is related to the functioning of BAT, home to brown adipocytes. BAT has been revealed to be a major site for lipid breakdown and glucose uptake. In fact, the thermogenic capacity of even small amounts of brown adipocytes has emerged as an attractive target for anti-diabesity (diabetes and obesity) therapies.

Assessing the combined effects of chemicals using non-animal methods

Main strengths of non-animal methods lie in their integrated use and putting into context different aspects of the hazard from combined exposure to multiple chemicals. But in order to benefit from these tools in the hazard assessment of mixtures, more guidance on their use is needed to facilitate a more widespread application.

EU Regulation on Medical Devices still poses dangers to patients' interests

The proposed Regulation on In Vitro Diagnostic Medical Devices (IVDs) negotiations, currently at the stage of tripartite negotiations between the Council (representing Member State governments), the European Parliament, and the European Commission, still risks restricting the rights of patients and doctors to carry out essential genetic testing, says the European Society of Human Genetics (ESHG) today (20 October 2015) in a statement issued by a range of organisations representing geneticists and patients.
