The Ministry of New and Renewable Energy has published the R&D; Roadmap for Green Hydrogen Ecosystem in India. This document was published on 13th October, 2023. One of the central pillars of the National Green Hydrogen Mission is the establishment of a supportive research and innovation ecosystem for green hydrogen …
This study addresses the evolutionary dynamics of antimalarial drug resistance after changes in drug use. We show that chloroquine resistance in Plasmodium falciparum from French Guiana was lost after sustained drug removal, whereas the resistance marker PfCRT K76T remained fixed in the parasite population. This phenotypic reversion was caused by …
Two natural dyes containing anthocyanin are extracted from sour and sweet pomegranate from Iran. Spectrophotometric evaluation of the natural dyes in solution and on a TiO2 substrate was carried out to assess changes in the status of the natural dyes. The results show that the natural dyes indicate buthochromic shift …
Nature has created excellent technologies around us, and as such, it is the chief mentor to humans on creativity and technology development. Nature uses fibre as a building block – natural structures like wood, bamboo, bone, muscle, etc. all have fibrous structure. Fibre spinning and weaving technologies are available in …
Antibiotic resistance among enterococci and γ-proteobacteria is an increasing problem in healthcare settings. Dense colonization of the gut by antibiotic-resistant bacteria facilitates their spread between patients and also leads to bloodstream and other systemic infections. Antibiotic-mediated destruction of the intestinal microbiota and consequent loss of colonization resistance are critical factors …
Culex quinquefasciatus is one of the principal vectors of West Nile virus (WNV). The mosquito also acts as a bridge vector as it feeds on both birds and humans. In the background of the recent reports of WNV activity in Kerala and Assam with fatalities, a study was initiated to …
Self-consciousness would seem to be a sine qua non for moral competence in a social world. You and we are morally competent in no small part because you know what you ought to do, and we know what we ought to do. A mouse, in contrast, cannot say to itself: …
The Public Health England (PHE) reported what it described as a “landmark review” of evidence about e-cigarettes. The headline in their press release quoted their top-line finding—“E-cigarettes around 95% less harmful than tobacco”. Kevin Fenton, Director of Health and Wellbeing at PHE, commented that, “E-cigarettes are not completely risk free …
Non-thermal microwave/lower frequency electromagnetic fields (EMFs) act via voltage-gated calcium channel (VGCC) activation. Calcium channel blockers block EMF effects and several types of additional evidence confirm this mechanism. Low intensity microwave EMFs have been proposed to produce neuropsychiatric effects, sometimes called microwave syndrome, and the focus of this review is …
Mice exposed to high levels of arsenic in utero are more susceptible to tumors such as hepatic and pulmonary carcinoma when they reach adulthood. However, effects of in utero arsenic exposure on general physiological functions such as reproduction and metabolism remain unclear. The researchers evaluated the effect of in utero …
Genomewide association studies can be used to identify disease-relevant genomic regions, but interpretation of the data is challenging. The FTO region harbors the strongest genetic association with obesity, yet the mechanistic basis of this association remains elusive. Original Source
Within the gastrointestinal tract vagal afferents play a role in control of food intake and satiety signalling. Activation of mechanosensitive gastric vagal afferents induces satiety. However, gastric vagal afferent responses to mechanical stretch are reduced in high fat diet mice. Transient receptor potential vanilloid 1 channels (TRPV1) are expressed in …
Conservation researchers have increasingly begun to use drones to conduct population counts of animals or study changing habitats. But new research suggests that wild black bears may be disturbed by a drone’s presence, prompting questions about the appropriate use of these devices in the field. Here, a brown-coated cub born …
The latest Ebola virus (EBOV) epidemic spread rapidly through Guinea, Sierra Leone, and Liberia, creating a global public health crisis and accelerating the assessment of experimental therapeutics and vaccines in clinical trials. One of those vaccines is based on recombinant vesicular stomatitis virus expressing the EBOV glycoprotein (VSV-EBOV), a live-attenuated …
A domestic sheep has given birth to a baby mouflon in a rare successful example of interspecies cloning, according to scientists in Iran. The wild Isfahan mouflon – or ovis orientalis isphahanica – was cloned by researchers at Iran’s Royan Institute, which is dedicated to reproductive biomedicine and stem cell …
Research has shown that genes play an important role in educational achievement. A key question is the extent to which the same genes affect different academic subjects before and after controlling for general intelligence. The present study investigated genetic and environmental influences on, and links between, the various subjects of …
A novel way of cooking rice to maximize the removal of the carcinogen inorganic arsenic (Asi) is presented here. In conventional rice cooking water and grain are in continuous contact, and it is known that the larger the water:rice cooking ratio, the more Asi removed by cooking, suggesting that the …
Energy ministers from the Southern African Development Community will discuss plans for a renewable-energy research center as countries throughout the region battle chronic blackouts. The center will focus on “practical implementation” of clean-energy technologies, Wolsey Barnard, deputy director-general for energy programs at South Africa’s Department of Energy, said Tuesday in …
We propose a model of a bus traveling through a sequence of traffic lights, which is required to stop between the traffic signals to pick up passengers. A two dimensional model, of velocity and traveled time at each traffic light, is constructed, which shows non-trivial and chaotic behaviors for realistic …
Children living in poverty generally perform poorly in school, with markedly lower standardized test scores and lower educational attainment. The longer children live in poverty, the greater their academic deficits. These patterns persist to adulthood, contributing to lifetime-reduced occupational attainment. The objective is to determine whether atypical patterns of structural …
Direct delivery of aerosolized vaccines to the respiratory mucosa elicits both systemic and mucosal responses. This vaccine strategy has not been tested for Ebola virus (EBOV) or other hemorrhagic fever viruses. Here, we examined the immunogenicity and protective efficacy of an aerosolized human parainfluenza virus type 3–vectored vaccine that expresses …
