'Helix-to-Tube'—a simple strategy to synthesize covalent organic nanotubes

Organic nanotubes (ONTs) are tubular nanostructures composed of organic molecules that have unique properties and have found various applications, such as electro-conductive materials and organic photovoltaics. A group of scientists at Nagoya University have developed a simple and effective method for the formation of robust covalent ONTs from simple molecules. This method is expected to be useful in generating a range of nanotube-based materials with desirable properties.

Physics news

Researchers use quantum dots to manipulate light

Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology. The study was published on August 30th in Nature Communications.

Invisibility cloak with photonic crystals

Almost as elusive as unicorns, finding practical materials for invisibility cloaking is challenging. Michigan Technological University researchers have new ideas how to solve that.

A 'nonlinear' effect that seemingly turns materials transparent is seen for the first time in X-rays at SLAC's LCLS

Imagine getting a medical X-ray that comes out blank – as if your bones had vanished. That's what happened when scientists cranked up the intensity of the world's first X-ray laser, at the Department of Energy's SLAC National Accelerator Laboratory, to get a better look at a sample they were studying: The X-rays seemed to go right through it as if it were not there.

Reducing runoff pollution by making spray droplets less bouncy

When farmers spray their fields with pesticides or other treatments, only 2 percent of the spray sticks to the plants. A significant portion of it typically bounces right off the plants, lands on the ground, and becomes part of the runoff that flows to streams and rivers—often causing serious pollution. But a team of MIT researchers aims to fix that.

New instrument improves studies of explosions, helps control hot spots

Testing explosions is epic science. The most detailed studies of explosive charges have been conducted at national laboratories using a gun as big as a room to fire a flat bullet—the flyer plate, typically 100 millimeters in diameter—into an explosive charge inside a thick-walled chamber that contains the fierce blast. The tests require enormous facilities.

Quest to find the 'missing physics' at play in landslides

During the 1990s, Charles S. Campbell, now a professor in the Department of Aerospace and Mechanical Engineering at the University of Southern California, began exploring why large landslides flow great distances with apparently little friction, and the larger the volume of flowing rock the lesser the friction.

New optical material offers unprecedented control of light and thermal radiation

A team led by Nanfang Yu, assistant professor of applied physics at Columbia Engineering, has discovered a new phase-transition optical material and demonstrated novel devices that dynamically control light over a much broader wavelength range and with larger modulation amplitude than what has currently been possible. The team, including researchers from Purdue, Harvard, Drexel, and Brookhaven National Laboratory, found that samarium nickelate (SmNiO3) can be electrically tuned continuously between a transparent and an opaque state over an unprecedented broad range of spectrum from the blue in the visible (wavelength of 400 nm) to the thermal radiation spectrum in the mid-infrared (wavelength of a few tens of micrometers). The study, which is the first investigation of the optical properties of SmNiO3 and the first demonstration of the material in photonic device applications, is published online today in Advanced Materials.

Theorists solve a long-standing fundamental problem

Trying to understand a system of atoms is like herding gnats - the individual atoms are never at rest and are constantly moving and interacting. When it comes to trying to model the properties and behavior of these kinds of systems, scientists use two fundamentally different pictures of reality, one of which is called "statistical" and the other "dynamical."

Colors from darkness: Researchers develop alternative approach to quantum computing

Earth news

Technique could assess historic changes to Antarctic sea ice and glaciers

Historic changes to Antarctic sea ice could be unravelled using a new technique pioneered by scientists at Plymouth University.

Increases in coastal development and precipitation push a parasite from land to sea

Coastal waters near heavy human development are more likely to receive land-based "pathogen pollution," which can include viruses, bacteria and parasites, according to a recent study from the University of California, Davis. The study said higher levels of rainfall and development increase the risk of disease-causing organisms flowing to the ocean.

Did meteorites bring life's phosphorus to Earth?

Meteorites that crashed onto Earth billions of years ago may have provided the phosphorous essential to the biological systems of terrestrial life. The meteorites are believed to have contained a phosphorus-bearing mineral called schreibersite, and scientists have recently developed a synthetic version that reacts chemically with organic molecules, showing its potential as a nutrient for life.

People enhanced the environment, not degraded it, over past 13,000 years

Fires pollute the air in West Africa

West Africa is changing rapidly. An explosively growing population, massive urbanization, and unregulated deforestation modify the composition of the atmosphere, thus affecting weather and climate. How exactly these emissions are changing the region in the long term is not clear. The EU-funded project DACCIWA coordinated by Karlsruhe Institute of Technology (KIT) therefore studied the air over the coastal region of West Africa with the help of research aircraft and ground stations.

Researchers show that when it comes to climate change and stream flow, plants play an important role

In California's Sierra Nevada mountains, as more precipitation falls in the form of rain rather than snow, and the snowpack melts earlier in spring, it's important for water managers to know when and how much water will be available for urban and agricultural needs and for the environment in general.

Impact of road transport on air quality not given sufficient priority in UK transport planning

UK transport planning is not sufficiently taking into account the environmental impacts of transport choices according to researchers from the Centre for Transport and Society and Air Quality Management Resource Centre at the University of the West of England (UWE Bristol).

Medicine & Health news

Behind the curtain: Abnormal discharge of striatal projection neurons in Parkinson's disease revealed

(Medical Xpress)—Parkinson's disease (PD) – an incurable, progressive illness caused by dysfunction and death of dopaminergic neurons in the brain (mainly in the substantia nigra) – results in a wide range of symptoms, motor system disorders such as tremors, akinesia (muscle rigidity), bradykinesia (slowed motion), and impaired balance (PD-related nonmotor symptoms include depression, gastrointestinal disorders, low blood pressure, and sleep disorders.) While PD can be managed with to varying degrees with medication and (less frequently) surgery, its precise cause has yet to be identified. At the same time, neuronal interconnection (or circuitry) models of Parkinson's disease are based on dopamine loss in a subcortical nucleus of the forebrain known as the striatum, as well as atypical striatal inputs into the basal ganglia (a neuronal network that plays a role in motor function and is thus relevant to PD and other neurological disorders manifesting with tremors and other involuntary movements). However, current research has been focused largely on extrastriatal mechanisms rather than striatal discharges in PD. Recently, however, scientists at Emory University School of Medicine, Atlanta, San Pablo University, Madrid and Instituto de Salud Carlos III, Madrid studied striatal projection neuron (SPN) patterns in PD patients undergoing deep brain stimulation (DBS) surgery, and compared that activity pattern with patients having the non-PD conditions essential tremor (ET) and isolated dystonia (ID) that lead to tremors and intermittent muscle contractions, respectively. The researchers found that their study provides significant insight into the role of striatal mechanisms in basal ganglia circuits and PD pathophysiology, as well as reports for the first time altered striatal SPN activity in dystonia and activity compatible with unchanged striatal function in ET.

The immune system's influence on sickness behaviour

It is hard to find the words to describe how I feel at the moment because my brain is only working at about 10% capacity. At least I made it to work today. This is an improvement on last week, when I decided to stay home after waking up exhausted with a warm and unpleasant throbbing pressure spreading into my eyeballs and across my sinuses.

Brain's internal compass also navigates during imagination

When you try to find your way in a new place, your brain creates a spatial map that represents that environment. Neuroscientists from Radboud University's Donders Institute now show that the brain's 'navigation system' is not only active during actual or virtual movement, but also when imagining view directions. This suggests that the brain's spatial navigation system might also be important for cognitive functions such as imagination and memory. Scientific journal eLife published the results on August 30.

First randomized trial compares stenting techniques for coronary bifurcation

Coronary bifurcations – a type of coronary artery narrowing – are best treated with a technique known as culotte stenting, as opposed to T-and-protrusion (TAP) stenting, when there is need for a side-branch stent according to results of the BBK II (Bifurcations Bad Krozingen) trial.

Cannabinoid receptor activates spermatozoa

Biologists from Bochum and Bonn have detected a cannabinoid receptor in spermatozoa. Endogenous cannabinoids that occur in both the male and the female genital tract activate the spermatozoa: they trigger the so-called acrosome reaction, during which the spermatozoon releases digestive enzymes and loses the cap on the anterior half of its head. Without this reaction, spermatozoa cannot penetrate the ovum. The researchers published their findings in Scientific Reports.

Systems biology research study reveals benefits of vacation and meditation

Scientists from the Icahn School of Medicine at Mount Sinai, the University of California, San Francisco, and Harvard Medical School used a rigorous study design to assess the biological impact of meditation compared to vacation. They examined the effect of meditation on gene expression patterns in both novice and regular meditators. The researchers found that a resort vacation provides a strong and immediate impact on molecular networks associated with stress and immune pathways, in addition to short- term improvements in well-being, as measured by feelings of vitality and distress. A meditation retreat, for those who already used meditation regularly, was associated with molecular networks characterized by antiviral activity. The molecular signature of long-term meditators was distinct from the non-meditating vacationers. The study was published today in Springer Nature's journal Translational Psychiatry.

Psychopaths feel fear but see no danger

Researchers from Vrije Universiteit Amsterdam and Radboud University Nijmegen found proof that psychopathic individuals can feel fear, but have trouble in the automatic detection and responsivity to threat. For many decades fear has been put forth as a hallmark feature of psychopathy, the impairments in which would lead to bold risk-taking behavior. Sylco Hoppenbrouwers (VU Amsterdam), Erik Bulten and Inti Brazil (Radboud University) reviewed theoretical and empirical brain and behavioral data pertaining to fear and psychopathy and found that psychopathic individuals have trouble detecting threats. There was however little evidence that the conscious experience of fear was affected, indicating that the experience of fear may not be completely impaired in psychopathy. It's the first study to provide empirical evidence that the automatic and conscious processes can be independently affected within one psychiatric disorder.
