Physics news

Pure quantum-mechanical mixture of electrons and photons demonstrated in bismuth selenide

In 2013, MIT physicists showed for the first time that shining powerful mid-infrared laser light on solid bismuth selenide produces Floquet-Bloch states, which are characterized by replicas of electronic energy states inside a solid with gaps opening up at crossing points of replica states. The same external light also interacts with free electron states immediately outside the solid producing a competing state, called the Volkov state, which is gapless.

Criteria to predict experimentally stable allotropes

(Phys.org)—A group of researchers from France, the U.K. and Florida proposes criteria to determine whether an allotrope is experimentally feasible. They use theoretical carbon allotropes, penta-graphene and Haeckelites, as examples and demonstrate why penta-graphene, contrary to recent research, is not experimentally practical while Haeckelites could be isolated in the presence of charge transfer ions. Their study appears in The Proceedings of the National Academy of Science.

Powerful protein promotes post-injury regeneration and growth of injured peripheral nerves

The peripheral nervous system is a vast network of nerves that exists primarily outside of brain and spinal cord and connects to the far reaches of the body. The very expanse of peripheral nerves makes them highly vulnerable to injuries such as blunt-force blows, cuts, and leg and arm fractures, as well as diseases that attack peripheral nerves such as diabetes, Charcot-Marie-Tooth, and Guillain-Barre syndrome. Unlike the central nervous system (brain and spinal cord), peripheral nerves do have the capacity to regenerate, and inflammatory immune responses play a key role in regeneration.

Anti-inflammatory drug and gut bacteria have a dynamic interplay, according to study

A nonsteroidal anti-inflammatory drug (NSAID) changed the composition and diversity of gut microbes, which in turn shaped how the drug is broken down and ultimately, cut its effectiveness, according to an animal study from the Perelman School of Medicine at the University of Pennsylvania. Gut bacteria that make up the gastrointestinal microbiome play an important role in the metabolism of most chemicals humans ingest, motivating studies of microbe-driven breakdown of clinically important drugs. In fact, gut bacteria are involved in the digestion of over 30 U.S. Food and Drug Administration (FDA)-approved drugs.

Stored fat is a feat of evolution

In spite of the bad press, stored fat is actually a really wonderful thing. Without the capacity to store energy in the form of fat, we would have been unlikely to survive through millions of years of evolution and we would certainly look very different to the way we look today. We needed the capacity to store energy to survive periods of famine, and fat is a very sensible way to do this.

Mental Synthesis experiment could teach us more about our imagination

While there is general consensus that the ability to imagine a never-before-seen object or concept is a unique and distinctive human trait, there is little that we know about the neurological mechanism behind it. Neuroscientist Dr. Andrey Vyshedskiy proposes a straightforward experiment that could test whether the ability to imagine a novel object involves the synchronization of groups of neurons, known as neuronal ensembles. Since the process involves mentally combining familiar images, scenes or concepts, Dr. Vyshedskiy proposes calling this process 'mental synthesis.' His research idea is published in the open-access Research Idea and Outcomes (RIO) Journal.

Sharing of research data and findings should be the norm in public health emergencies

Team finds possible new pharmacological target for one of the most important and elusive oncogenes

The MYC oncogene intervenes in many types of cancer, some of which are very aggressive; researchers suspect that controlling its activity could open avenues to new treatments. However, MYC is an especially complex oncogene that has resisted therapeutic manipulation to date. Researchers of the Spanish National Cancer Research Centre (CNIO) have now managed to identify a protein that is essential for MYC to cause cancer in mouse models, and they believe that it could be a new target for future anti-cancer drugs. The paper, which has been published today in Nature Communications, uses genome wide data analysis techniques to study the behaviour of MYC in networks that consist of hundreds of genes.

Parkinson's disease: New insights into a traveling protein

In Parkinson's disease, the protein "alpha-synuclein" aggregates within neurons of patients and appears to propagate across interconnected areas of the brain. How this happens remains largely unknown. It has been proposed that alpha-synuclein may behave like a "prion": pathological forms of the protein may be capable of changing the conformation of normal alpha-synuclein and thus triggering its aggregation and neuron-to-neuron propagation (a phenomenon referred to as "seeding"). Recent findings by scientists at the German Center for Neurodegenerative Diseases (DZNE) reveal that aggregation, spreading and pathology caused by alpha-synuclein do not necessarily involve prion-like seeding. Instead, they could be triggered by enhanced alpha-synuclein expression and trans-neuronal passage of monomeric and oligomeric forms of the protein. Researchers led by Prof. Donato Di Monte report on this in the journal Brain.

Why white, older men are more likely to die of suicide

Biogerontology Research Foundation calls for a task force to classify aging as a disease

The first paper published on June 15th, the authors provide a set of arguments for classifying ageing as a disease. The paper by Bulterijs, Roy and colleagues propositions that disease classification is too often dependent on social and cultural context, and that separating 'normal' progression from 'healthy' aging lacks coherence and hinders efforts to ameliorate age-related suffering. For example, several currently recognized diseases, such as osteoporosis, isolated systolic hypertension, and senile Alzheimer's disease, were in the past ascribed to normal aging. Recognising aging as a unique, but multisystemic disease would provide a framework to tackle and prevent many chronic conditions; alleviating both financial, social and moral burden.
