In the minuscule world of nanotechnology, big steps are rare. But a recent development has the potential to massively improve our lives: an engine measuring 200 billionths of a metre, which could power tiny robots to fight diseases in living cells.

Drug delivery that hits the dot

Drug treatments are made more efficient by delivering them to specific sites in the body where they are needed. For example, specific targeting of anticancer drugs to tumour sites could reduce required doses, provide more sustained effects and minimise side effects. Such targeting is possible by encapsulating drugs in polymeric nanoparticles, or nanocapsules, that transport them through the body to their targets. However, the properties of various nanocapsules and of drugs can vary, and testing the effectiveness of different systems can be difficult.

Physics news

First movies of droplets getting blown up by x-ray laser

Researchers have made the first microscopic movies of liquids getting vaporized by the world's brightest X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. The new data could lead to better and novel experiments at X-ray lasers, whose extremely bright, fast flashes of light take atomic-level snapshots of some of nature's speediest processes.

Ultra-fast method to create terahertz radiation advances materials science

Revealing the nature of magnetic interactions in manganese oxide

For nearly 60 years, scientists have been trying to determine how manganese oxide (MnO) achieves its long-range magnetic order of alternating up and down electron spins. Now, a team of scientists has used their recently developed mathematical approach to study the short-range magnetic interactions that they believe drive this long-range order. By comparing measurements of the local magnetic interactions in MnO with those predicted by competing theoretical models, they determined that the antiparallel electron spin alignment is due to neighboring Mn ions interacting magnetically through an intermediary nonmagnetic oxygen ion—a mechanism called superexchange.

Optics breakthrough to revamp night vision

A breakthrough by an Australian collaboration of researchers could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture.

Researchers propose new method for creating extremely strong spin currents

In our computer chips, information is transported in form of electrical charge. Electrons or other charge carriers have to be moved from one place to another. For years scientists have been working on elements that take advantage of the electrons angular momentum (their spin) rather than their electrical charge. This new approach, called "spintronics" has major advantages compared to common electronics. It can operate with much less energy.

How much can a mode-2 wave move?

Look out over the ocean and you might get the impression that it's a mass of water acting as a single entity. However, the world's oceans are made up of layers of different densities, called stratifications, with complex fluid dynamics. Often bulges, called mode-2 internal waves, form in the thickness of these layers, trapping materials inside that then move along with the wave.

The team also suggests a way of enhancing the effect. The results of the study have been published in the journal Physical Review B.

Low temperature heterogeneous integration without glue

Realization of large scale photonic integration for one-chip optical routers is crucial for future optical networks and interconnection for big data transmission and artificial intelligence technology. To meet these technical needs, platforms based on silicon photonic integrated circuits are expected to play an important role because of the availability of large diameter wafers and CMOS fabrication technology.

Bug-zapping lasers could add new weapon to our insect-fighting arsenal

Control and monitoring of disease-vector insects are critical to global health, as insect vectors spread pathogens among humans, animals and agricultural products, creating worldwide strain on health care and food resources. Mosquito-borne malaria, for example, caused over 200 million infections and over 400,000 deaths in 2015, according to the World Health Organization. A small insect is also to blame for the jump in the price of orange juice in recent years. The Asian citrus psyllid, a vector of citrus greening disease, has devastated orange groves in Florida and threatened citrus production around the world.

Hunting for dark matter's 'Hidden Valley'

Researchers focusing on the fragmentation of plastic waste

First discovered by sailors, the masses of plastic debris floating at the center of vast ocean vortices called gyres are today under close scrutiny by scientists. To better understand the fragmentation of microplastics under the effect of light and abrasion by waves, researchers combined physico-chemical analyses with statistical modeling. They were thus able to show that pieces of plastic debris behave in very different ways according to their size. The bigger pieces appear to float flat at the surface of the water, with one face preferentially exposed to sunlight. However, the researchers observed fewer small-sized debris (around 1 mg) than predicted by the mathematical model. Several hypotheses are put forward to explain this lack. The findings were obtained by researchers from CNRS and Université Toulouse III – Paul Sabatier from samples collected during the 7th Continent Expedition. They are published in the journal Environmental Science: Nano on 23 May 2016.

Astronomy & Space news

Scientist suggests possible link between primordial black holes and dark matter

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe's existence, known as primordial black holes. Now a scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, suggests that this interpretation aligns with our knowledge of cosmic infrared and X-ray background glows and may explain the unexpectedly high masses of merging black holes detected last year.

Study documents African monkeys eating bats

Although Cercopithecus monkeys, a widely distributed genus in Africa, usually have a discerning palate for fruits and leaves, they are opportunistic omnivores that sometimes consume lizards, snakes, birds and mice. These forest-dwelling primates share habitat and food resources with bats, which are known reservoirs for zoonotic diseases such as Ebola, Marburg and Henipa viruses as well as bacteria and parasites that can be spread between animals and humans. This has led researchers to hypothesize that primate consumption of fruits contaminated with an infected bat's saliva or feces facilitates zoonotic disease transmission. Scientists estimate that more than six out of every 10 infectious diseases in humans are spread from animals.

Is ecotourism an effective conservation tool?

Nature is in trouble. Across the globe, degradation and loss of habitat, over-exploitation of natural resources, and human-induced changes in climate are causing species to decline at an unprecedented speed. As the rate of global biodiversity loss is increasing, there are a growing number of species that need investment in conservation programs. However, the amount of available funding falls well below what is required to halt the global conservation crisis. With restrictions in financial support limiting the action that can be taken to prevent biodiversity loss, ecotourism is becoming an increasingly important source of revenue for conservation efforts.

Smoking during pregnancy associated with increased risk of schizophrenia in offspring

A study by researchers at Columbia University's Mailman School of Public Health, Columbia University Medical Center (CUMC), New York State Psychiatric Institute and colleagues in Finland reports an association between smoking during pregnancy and increased risk for schizophrenia in children. The paper evaluated nearly 1,000 cases of schizophrenia and matched controls among offspring born in Finland from 1983-1998 who were ascertained from the country's national registry. Results showed that a higher maternal nicotine level in the mother's blood was associated with an increased risk of schizophrenia among their offspring. The findings persisted after adjusting for important confounding factors including maternal and parental psychiatric history, socioeconomic status, and maternal age. The study provides the most definitive evidence to date that smoking during pregnancy is associated with schizophrenia.

New disease gene will lead to better screening for pediatric heart disease

Cardiomyopathy, or a deterioration of the ability of the heart muscle to contract, generally leads to progressive heart failure. It is frequently inherited, and, because approximately 40% of children born with it are likely to die within five years of diagnosis, being able to identify its genetic basis is particularly important. Now, an international team of researchers has identified a new disease gene which is implicated in the development of severe paediatric cardiomyopathies. The gene is probably also involved in a milder, adult-onset form of the condition.

Epigenetic modification increases susceptibility to obesity and predicts fatty liver

Scientists of the German Center for Diabetes Research (DZD), led by the German Institute of Human Nutrition (DIfE), have demonstrated that the epigenetic modification of the Igfbp2 gene observed in young mice precedes fatty liver in adulthood. In addition, young animals with this modification exhibit impaired glucose metabolism and are significantly more prone to morbid obesity. Annette Schürmann of DIfE said, "In morbidly obese people with incipient diabetes, we were able to demonstrate this modification in the corresponding gene. In the future, it may potentially be used as a risk marker."

Touch creates a healing bond in health care

In contemporary health care, touch – contact between a doctor's hand and a patient – appears to be on its way out. The expanding role of CT and MRI imaging is decreasing reliance on touch as a way of making diagnoses. Pressures to move patients through the system more quickly leave health professionals with fewer opportunities to make contact. Our experience suggests that when doctors spend fewer minutes with patients, less time is available for touch.

Oncologists need to better discuss patient life expectancy

Despite their nearness to death, a sizeable proportion of advanced cancer patients remain unaware of basic information about their illness or its treatment, researchers from Weill Cornell Medicine report. Reviewing test results with their oncologist not only improves patients' understanding of the fatal nature of their illness, but also helps to inform their decisions about care.

Closer to the source of the itch

Psoriasis is an inflammatory skin condition that affects some 125 million people worldwide. It is characterized by itchy, scaly skin plaques. The exact cause of psoriasis is unclear. But mounting evidence implicates the immune system in the overproduction of cell-signalling molecules called cytokines, which stimulate skin cells called keratinocytes to express genes that maintain an inflammatory microenvironment. Now, scientists at Hokkaido University in Japan have found more evidence that a cytokine called IL-17A is especially critical in this process.

How neural circuits implement natural vision

At any given moment, the neuronal circuits in the brain receive and process sensory information that permits us to perceive and interact with the environment. Yet it remains unclear how the visual brain processes natural stimuli. Together with an international team of researchers from the Centre Nationale de la Recherche Scientifique (CNRS) in Marseille, the CNRS in Gif-Sur-Yvette, and New York State University, neuroscientists Jens Kremkow and Ad Aertsen from the Bernstein Center Freiburg have developed a new computational model that simulates how neurons in the visual cortex process sensory stimuli. This model may help neuroscientists to better understand how neuronal networks in the visual system process natural stimuli. The study has now been published in the journal Frontiers in Neural Circuits.

Facebooking your doctor's appointment

Current screening methods miss worrisome number of persons with mild cognitive impairment

Mild cognitive impairment (MCI) is a slight but noticeable and measurable decline in cognitive abilities, such as remembering names or a list of items. While changes may not be severe enough to disrupt daily life, a clinical diagnosis of MCI indicates an increased risk of eventually developing Alzheimer's disease or another type of dementia.

Opinion: More accountability needed in how drugs are priced and reimbursed

Approving new medicines that hit the market is the responsibility of the EU, but it is left up to individual member states to decide which ones they wish to subsidise. New prescription medicines can be very expensive and few patients could afford novel drugs for cancer and especially rare conditions if they had to pay out of their own pockets. But, thanks to state subsides, what most EU patients pay is only a fraction of the original price, be it in the form of a flat prescription fee (as happens in England) or various levels of patient co-payment depending on the patient and the medicine (as happens in Poland).

Chemo, radiation, surgery combo boosts survival for pancreatic cancer patients

In roughly one-third of pancreatic cancer patients, tumors have grown around the pancreas to encompass critical blood vessels. Conventional wisdom has long held that surgery to remove the tumors is rarely an option, and life expectancies are usually measured in months. Mayo Clinic, teaming oncologists, gastrointestinal and vascular surgeons and others, is finding that many of these patients actually are candidates for surgery. Mayo has been fine-tuning a protocol to treat them, and in two studies, found survival now stretching into years.

Wire bristles from barbecue brushes can cause serious injuries

While many people view Memorial Day weekend as the unofficial start of the summer grilling season, they may not be aware of the dangers of eating food cooked on grills cleaned with wire-bristle brushes. A new study conducted at the University of Missouri School of Medicine identified more than 1,600 injuries from wire-bristle grill brushes reported in emergency rooms since 2002. Loose bristles can fall off the brush during cleaning and end up in the grilled food, which, if consumed, can lead to injuries in the mouth, throat and tonsils. Researchers advise individuals to inspect their food carefully after grilling or consider alternative grill-cleaning methods.

Despite pressing need, survey finds most americans unlikely to enroll in clinical trials

The lack of participation in clinical research may be the Achilles' heel of today's cancer community. According to a new survey of more than 1,500 consumers and nearly 600 physicians conducted on behalf of Memorial Sloan Kettering Cancer Center (MSK), only 35 percent of Americans indicated that they were "likely" to enroll in a clinical trial. Other studies have shown that only 4 percent of cancer patients enroll in clinical trials nationally each year.

Effective protection for non-smokers could prevent 30% of all cancer deaths

Every year, lung cancer causes around 1.6 million deaths worldwide. 70% of all lung cancer patients throughout the world are smokers or ex-smokers and, in Central Europe, this figure is higher than 80%. Smoking is therefore regarded as the central risk factor for this disease. On occasion of World No Tobacco Day (31st May 2016) Robert Pirker, cancer expert from the Comprehensive Cancer Center (CCC) at MedUni Vienna and Vienna General Hospital, is therefore calling for improved protection for non-smokers and redoubled efforts in the area of smoking prevention.

(Phys.org)—A trio of researchers has, by conducting two studies, found evidence that suggests untrained polling callers are able to "guess" with almost 60 percent accuracy, which people they call will actually follow through on claims they have made regarding whether they will vote in an upcoming election. In their paper published in Proceedings of the National Academy of Sciences, Todd Rogers, with Harvard University and Leanne Brinke and Dana Carney with the University of California, describe their two studies and their assessment of possible signals given by respondents that potentially serve as cues to polling callers that give away their true intent.

Study finds little change in the IMF's policy advice, despite rhetoric of reform

A new study, the largest of its kind, has systematically examined International Monetary Fund (IMF) policies over the past three decades.

The cost of being poor, as told by toilet paper

One of the greatest fictional stories isn't a summer blockbuster and doesn't star a big-budget Hollywood celebrity. It's the story that individuals are poor due to their lack of will/drive/desire, and if they worked harder, they'd work themselves out of poverty. We like to call it the "American Dream." Perhaps the most effective endorsement of this story is that people continue to believe it, despite U.S.-based data proving the opposite. In fact, the poverty rate in the US remained mostly consistent from 1966 to 2014, fluctuating from 15% to 11% (US Census, Table 2).

Organizational innovations to accelerate technology transfer and translational research do they work?

Innovations in life sciences, engineering, and technology have enabled new products in numerous sectors such as innovative diagnostics, treatments for human and animal health, medical devices, advances in communication, e-learning, aviation, and 3D printing. Yet transfer of scientific discovery and technology to innovation-in-society is onerous, and can take several decades to materialize. In order for societies to fully enjoy the expected benefits of technology investments, research findings have to be moved from "lab to society."
