Scientists apply 'twistronics' to light propagation and make a breakthrough discovery

A research team led by scientists at the Advanced Science Research Center at The Graduate Center, CUNY (CUNY ASRC), in collaboration with National University of Singapore, University of Texas at Austin and Monash University, has employed "twistronics" concepts (the science of layering and twisting two-dimensional materials to control their electrical properties) to manipulate the flow of light in extreme ways. The findings, published in the journal Nature, hold the promise for leapfrog advances in a variety of light-driven technologies, including nano-imaging devices; high-speed, low-energy optical computers; and biosensors.

Researchers discover skyrmions can split like biological cells

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that skyrmions— a type of quasiparticle with properties that could lead to the next generation of data storage and transfer— reproduce by splitting in a way very similar to biological cell division.

Researchers synthesize silicon-based quantum dots

NDSU researchers recently developed a new method of creating quantum dots made of silicon. Quantum dots, or nanocrystals, are tiny nanometer-scale pieces of semiconductor that emit light when their electrons are exposed to UV light. The most common application of quantum dots is in QLED displays. Through their use, digital displays have become brighter and much thinner, resulting in improvements to television and, potentially, cell-phone technology.

Extremely brilliant giga-electron-volt gamma rays from a two-stage laser-plasma accelerator

Laser-wakefield accelerators have led to the development of compact, ultrashort X-ray or gamma-ray sources to deliver peak brilliance, similar to conventional synchrotron sources. However, such sources are withheld by low efficiencies and limited to 107-8 photons per shot in the kiloelectron volt (KeV) to megaelectron volt (MeV) range. In a new report now published on Science Advances, Xing-Long Zhu and a research team in physics and astronomy in China and the U.K., presented a new approach to efficiently produce collimated, ultrabright gamma (γ)-ray beams. The resulting photon energies were tunable for up to gigaelectron volts by focussing a multi-petawatt laser pulse into a 2-stage wakefield accelerator. The high-intensity laser allowed them to efficiently generate a multi-gigaelectron volt electron beam with a high density and charge during the first stage of the experiment. The laser and electron beams entered a high-density plasma region in the second stage thereafter. Using numerical simulations, they demonstrated the production of more than 1012 gamma ray photons per shot with energy conversion efficiency above 10 percent for photons above 1 megaelectron volt (MeV) and achieved a peak brilliance above 1026 photons S-1mm-2mrad-2 per 0.1 percent bandwidth at 1 MeV. This research outcome will offer new avenues in both fundamental and applied physics and engineering.

Scientists carry out first space-based measurement of neutron lifetime

Physics principle explains order and disorder of swarms

Current experiments support the controversial hypothesis that a well-known concept in physics—a critical point—is behind the striking behavior of collective animal systems. Physicists from the Cluster of Excellence Centre for the Advanced Study of Collective Behavior at the University of Konstanz showed that light-controlled microswimming particles can be made to organize into collective states such as swarms and swirls. By studying the particles fluctuating between these states, they provide evidence for critical behavior—and support for a physical principle underlying the complex behavior of collectives. The research results were published in the scientific journal Nature Communications.

Ultra-thin camera lenses of the future could see the light of day

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making artificial materials known as metasurfaces, which consist of a multitude of interacting nanoparticles that, together, can control light. They could have great use in the optical technology of tomorrow.

Exotic electron-electron interactions found unnecessary for conduction in nickelates

Some metal oxides, such as nickelates, have a tuneable resistivity, which makes them an interesting material for adaptable electronics and cognitive computing. These materials can change their nature from metallic to insulating. How exactly this metal-insulator transition takes place is a topic of great interest in condensed matter physics. However, even the metallic behavior in nickelates seems unusual. Scientists from the University of Groningen, together with colleagues from Spain, have now found that it is not as complex as was previously assumed. The results were published on 11 June in the journal Nature Communications.

A breakthrough in developing multi-watt terahertz lasers

Terahertz lasers could soon have their moment. Emitting radiation that sits somewhere between microwaves and infrared light along the electromagnetic spectrum, terahertz lasers have been the focus of intense study due to their ability to penetrate common packaging materials such as plastics, fabrics, and cardboard and be used for identification and detection of various chemicals and biomolecular species, and even for imaging of some types of biological tissue without causing damage. Fulfilling terahertz lasers' potential for us hinges on improving their intensity and brightness, achieved by enhancing power output and beam quality.

Matrix imaging: an innovation for improving ultrasound resolution

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis. Researchers at the Institut Langevin (CNRS/ESPCI Paris-PSL)1 have developed a new non-invasive ultrasound method that avoids such aberrations.

Earth news

Scientists detect unexpected widespread structures near Earth's core

University of Maryland geophysicists analyzed thousands of recordings of seismic waves, sound waves traveling through the Earth, to identify echoes from the boundary between Earth's molten core and the solid mantle layer above it. The echoes revealed more widespread, heterogenous structures—areas of unusually dense, hot rock—at the core-mantle boundary than previously known.

More than 1000 tons of plastic rains into western US protected lands annually

Novel noncovalent bond blocks repulsive odor of isocyanides

Isocyanides are an important class of organic compounds owing to a wide range of chemical transformations they can undergo. These molecules are employed for the synthesis of various pharmaceuticals, polymers, catalysts, and luminophores. Widespread use of isocyanides in chemistry and chemical industry is, however, hampered by their extremely foul odor, described by some researchers as "mind-boggling," "horrid" and even "murderous." Luca Turin, one of the leading experts in fragrance chemistry, called isocyanides "the Godzilla of scent." This odor is so terrible that the United States patented the use of isocyanides (generally low on the toxicity scale) as a non-lethal chemical weapon.

Biology news

Dopamine signaling allows neural circuits to generate coordinated behaviors

For a nematode worm, a big lawn of the bacteria that it eats is a great place for it to disperse its eggs so that each hatchling can emerge into a nutritive environment. That's why when a worm speedily roams about a food patch it methodically lays its eggs as it goes. A new study by neuroscientists at MIT's Picower Institute for Learning and Memory investigates this example of action coordination—where egg-laying is coupled to the animal's roaming—to demonstrate how a nervous system coordinates distinct behavioral outputs. That's a challenge many organisms face, albeit in different ways, during daily life.

A thousand elephants threatened by starvation have journeyed through the hills of northern Thailand, making a slow migration home from tourist sites forced shut by the pandemic.

Kissing bugs also find suitable climatic conditions in Europe

An infection with Chagas disease is only possible in Latin America since the insect species that spread the disease only occurs there. Scientists at Goethe University and the Senckenberg Society for Natural Research have now used ecological niche models to calculate the extent to which habitats outside of the Americas may also be suitable for these insects. The result: Climatically suitable conditions can be found in southern Europe for two kissing bug species; along the coasts of Africa and Southeast Asia, the conditions are suitable for yet another species. The Frankfurt scientists therefore call for careful monitoring of the current distribution of triatomine bugs.

Sustainable cover-crop farming practice faces one big limitation: Land to produce seeds

As farmers around the globe look to grow food more sustainably—with less water, fertilizer, pesticides and other environmental impactors—the use of cover crops is becoming more popular. These crops, which are often grasses or legumes, or many other types of plants, are generally grown between the harvest and planting season of the land's main cash crop, to reduce erosion, build soil fertility and control weeds, among other benefits. Their use has jumped in recent years. From 2012 to 2017, U.S. cover crops increased to 6.2 million hectares, an increase of 50%.

Researchers identify 'hot spots' for developing lymphatic vessels

When an embryo develops, a wide variety of proteins and enzymes trigger a series of biochemical reactions. The development of the lymphatic vasculature is crucially dependent on one specific protein—the growth factor VEGF-C. In order to become biologically active and to initiate downstream signaling events, the protein must first undergo processing steps. Thus far it was unclear, however, how and where the necessary factors come together that are required for VEGF-C activation, and which cell types provide these individual factors during development.

Experts clarify subtypes of multiple sclerosis to improve care and clinical trials

An international committee of multiple sclerosis (MS) experts has clarified their previously published descriptors of the different courses of MS and disease activity. MS subtypes are consensus definitions rather than pathologically defined phenotypes, and are easily misconstrued. The review was prompted in part by differences in specified indications for MS therapies recently approved by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA). The goal of the review is to improve care and access to treatments, and to refine the selection of clinical trial participants so that trial outcomes can be better applied to clinical care.

How can physicians flourish?

Doctors can only perform at the best of their ability in an environment that acknowledges and strengthens 'calling and comradeship.' According to Ph.D. student Myra van den Goor of the University of Twente, these human- and relationship-directed values have been pushed to the background in recent years by a more commercial, business-like climate in health care—one dominated by the importance of procedures and efficiency. Van den Goor: "I argue that attention should once again be directed towards the person, rather than towards process, registration and production. My findings and recommendations show how doctors work at a high level of performance in an extremely dynamic environment, and what they need in order to remain 'simply' good doctors."

Photographic protocol developed to plan breast cancer surgeries

Breast cancer is most common among women: More than half a million new cases were detected in the European Union in 2018. Surgery and breast reconstruction are part of the treatment in a high percentage of cases, by way of oncoplastic techniques that require a broad image study to design the most suitable and personalized surgical strategy. However, there was no standardized protocol to establish the requirements for a full photographic study, from all viewpoints and with an optimum image quality, while also preserving patient privacy and comfort. Research professors from the Degrees in Medicine and Industrial Design at the CEU Cardenal Herrera University (CEU UCH) have collaborated in this first photographic protocol proposal for breast cancer surgery, with the participation of students and in collaboration with the National Autonomous University of Mexico (UNAM).

Fentanyl tops list of drugs found in Baltimore overdose patients

A new University of Maryland study found fentanyl tops the list of drugs detected in overdose patients at two Baltimore hospital emergency departments. The finding suggests that hospitals and medical systems throughout the United States consider adding fentanyl, a potent synthetic opioid linked to most fatal overdoses in Maryland, to their routine drug testing panels. That is the conclusion of researchers at the University of Maryland School of Medicine (UMSOM) and the Center for Substance Abuse Research (CESAR) at the University of Maryland, College Park. Currently, fentanyl is not routinely included in these panels nationwide. The study is based on de-identified urinalysis results and other data collected through the new Maryland Emergency Department Drug Surveillance (EDDS) system, launched to support improved patient outcomes.

Cold plasma against the coronavirus

Many seriously ill COVID-19 patients must contend with more than just the coronavirus. Approximately half of the people who were mechanically ventilated yet still died had acquired additional infections in hospital. Cold plasma therapy could prevent these superinfections and reduce the risk of hospital staff becoming infected with coronavirus. Preliminary tests carried out by terraplasma medical GmbH, the subsidiary of the Max Planck spin-off terraplasma, suggest that cold atmospheric plasma (i.e. weakly ionized air) can render SARS-CoV-2 harmless in cell cultures. In order to clarify whether cold plasma can actually help treat COVID-19, investigations in both cell cultures and COVID-19 patients have been initiated together with various partners.
