Experiments confirm a quantum material’s unique response to circularly polarized laser light

Added: 26.10.2021 19:18 | 10 views | 0 comments

Scientists are probing topological insulators with circularly polarized light to reveal their many secrets. These exotic materials have potential for quantum computing and other technologies. They discovered that high harmonic generation produces a unique signature from the topological surface.

Fighting multiple sclerosis with cold

In evolutionary biology, the 'Life History Theory,' first proposed in the 1950s, postulates that when the environment is favorable, the resources used by any organism are devoted for growth and reproduction. Conversely, in a hostile environment, resources are transferred to so-called maintenance programs, such as energy conservation and defense against external attacks. Scientists developed this idea to a specific field of medicine: the erroneous activation of the immune system that causes autoimmune diseases. By studying mice suffering from a model of multiple sclerosis, the research team succeeded in deciphering how exposure to cold pushed the organism to divert its resources from the immune system towards maintaining body heat.

Mechanism underlying the emergence of virus variants unraveled

Added: 26.10.2021 19:18 | 2 views | 0 comments

Scientists have probed the molecular origins of recombination in RNA viruses. Hiccups during the copying process of viruses cause recombination to take place: the exchange of segments of viral RNA. While this can lead to the emergence of new virus variants, the mechanism can also be exploited to induce non-viable defective viruses

Breaking trade-off problem that limits thermoelectric conversion efficiency of waste heat

Added: 26.10.2021 18:18 | 2 views | 0 comments

Scientists demonstrate that breaking the trade-off problem between thermopower and conductivity improves thermoelectric performance. They suggest introducing lattice strain into Mott insulator oxide LaTiO3 converts the electronic state to metal, and increases both thermopower and conductivity to induce a 100-fold increase in power factor, which in turn enables the conversion of waste heat to electricity more efficiently. Their findings could help ensure a more energy-efficient future.

New PCR assays offer hope in the fight against the environmental spread of antimicrobial resistance

Added: 26.10.2021 18:18 | 4 views | 0 comments

Researchers have successfully trialed two new qPCR assays to help detect the presence of transmissible AMR using water and wastewater samples. The scientists present a DNA-based testing method that provides a surrogate for monitoring AMR, which will make AMR screening cheaper and more accessible around the world.

In a series of experiments that began with amoebas -- single-celled organisms that extend podlike appendages to move around -- scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.

Immune cell implicated in development of lung disease following viral infection

Added: 26.10.2021 17:59 | 1 views | 0 comments

Scientists have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
