The study, which is yet to be peer reviewed, looked into the cases of 44 vaccinated and 22 non-vaccinated long COVID patients.

Before vaccination, most patients showed serious symptoms and complained of fatigue, breathlessness and insomnia.

In January and February, a few of the participants received their vaccine shot, following which their symptoms were matched to those who were yet to get vaccinated. A month later, both the groups were reassessed and were asked whether their symptoms had improved, worsened or stayed the same.

Researchers found a 5.6 per cent decrease in worsening symptoms and 23.2 per cent increase in symptom resolution among the vaccinated participants in opposition to 14.2 percent and 15.4 percent for the unvaccinated respectively.

However, the scientists clarify that the study is too small “to make firm conclusions.” According to them, more research needs to be conducted in support of the claim.

Number of OCI cards issued has doubled since last 5 years | India News – Times of India

[ad_1]

Read More/Less


NEW DELHI: As many as 3.2 lakh overseas citizens of India (OCI) cards were issued per annum between 2015 and 2021 as compared to an average 1.7 lakh cards issued per year between 2005 and 2014. This, a home ministry official said, pointed to the growing popularity of the OCI card scheme with the Indian diaspora “in view of the OCI application process being made online and various relaxations offered over the years to extend the coverage and benefits of the scheme”.
The government, through an executive order in 2019, had revised the OCI guidelines to require OCI cardholders to take special permission for undertaking activities like research, missionary work, Tablighi work, mountaineering and journalism and for visiting restricted, protected or prohibited areas while on a multiple entry, life-long visa, the changes were given statutory backing last week through a notification in the gazette. Prior to 2019, such permission was required only for research work.
“These are not new restrictions and were in existence and in the public domain since 2019. The notification does not further restrict the pursuit of these activities. OCI cardholders can do all major activities without any permission from government authorities,” a home ministry official said.
“This notification does not in any way take away the rights and privileges of an OCI cardholder as specified in various FEMA regulations,” he added. Stating that the government had facilitated foreigners eligible for or registered as OCI cardholder to a great extent, the official said these initiatives had led to the number of OCI cards issued doubling in the last six years.

Multipurpose herb

Published in Current Biology

Catnip (Nepeta cataria), a garden herb known for its hallucinogenic effects on domestic cats, is also used to ward off insects, especially mosquitoes. A new study has now decoded how the plant does this. The researchers found that Catnip and its active ingredient Nepetalactone activates an irritant receptor called TRPA1.

Welcome to Bahamas

Published in PNAS

Who were the original inhabitants of the picturesque Bahamas? When did they arrive? A detailed study of the fire and vegetation (of the last 3,000 years) showed that indigenous people called Lucayans arrival in the northern Bahamas at around 830 CE. “While people were present in Florida more than 14,000 years ago at the end of the last ice age, these people never crossed the Florida Straits to nearby Bahamian islands, only 80 to 105 km away…Meanwhile, the Caribbean islands were populated by people migrating from South American northward,” explains Peter van Hengstum, one of the authors in a release.

Frogs and noise-cancellation

Published in Current Biology

To find a suitable partner, male frogs sit in one place and call loudly. But how does the female hear and select the male of her species among all the other background noise and overlapping calls of other frog species? Their lungs act as noise-canceling headphones says a new study. The lungs when inflated were found to reduce their eardrum’s sensitivity to noise in a particular frequency range, making it easier to hear their mate’s calls.

Meet Gliese 486 b, a new exoplanet found orbiting the red dwarf star Gliese 486. The exoplanet is 2.81 Earth masses, 1.31 Earth radii and is a Super-Earth (exoplanet larger than Earth and smaller than Neptune). “The gravity is also 70% stronger than on Earth, making it harder to walk and jump. Someone who weighed 50 kg on Earth would feel like they weighed 85 kg on Gliese 486b, explains astronomer José Antonio Caballero in a release.

Oil spill cleaner

Published in Advanced Materials

A new resin membrane could soon help clean up beaches contaminated with oil spills. Named SAVER (superamphiphilic vitrimer epoxy resin) membranes, they can separate oil and water efficiently. The paper reports that it is similar to classical epoxy resins and “the blocked membrane can be easily recovered when contaminated…recycled, and re‐used.”

Clustering educational institutes and research centres

[ad_1]

Clustering is a promising model to achieve a critical mass in a university to invigorate research

National Education Policy 2020 (NEP) envisions establishing large multidisciplinary universities to promote research directed to solve contemporary national problems, and provides the option of setting up clusters of higher education institutes. Cluster-based universities would increase faculty strength, both in terms of numbers and diversity of disciplines, and facilitate conduct of research on real life problems.

Mainstay of research

Doctoral students are the mainstay of research in universities. In many countries including India, universities also conduct off-campus doctoral programmes in research laboratories. The Indian Institute of Science pioneered a variant of off-campus programme called External Registration programme which enabled employees working in laboratories or industries to register for a doctoral programme under the supervision of its faculty and carry out a major part of research at their workplace. The external registration programme has now been adopted by more higher education Institutes. The topic of research taken upunder off-campus programmes is always of relevance to the workplace. One could go a step further and make workplaces pursuing knowledge-based work a part of a cluster-based university.

Homi Bhabha National Institute (HBNI), Mumbai, established in 2005, by the Department of Atomic Energy, is a cluster-based university and I have had a long association with it. Jet Propulsion Laboratory (JPL), California, U.S., is a federally funded research and development centre managed by California Institute of Technology (Caltech).

The intellectual environment and identity of JPL are profoundly shaped by its role as a part of Caltech. A large laboratory, JPL has about 6,000 full time employees, and Caltech was placed eighth in the Academic Ranking of World Universities (ARWU) by Shanghai Rankings in 2020.

SOKENDAI (the Graduate University for Advanced Studies) established in Japan in 1988 and running only doctoral programmes, brings together several research institutions and museums such as the National Museum of Japanese History.

The Paris-Saclay University received its legal status in 2019, though it has been functioning as a “university system” since 2015. The university shares 275 laboratories with several research organisations, including CEA (Atomic Energy and Alternate Energies Commission), INSERM (French Institute of Health and Medical Research) and others. Though just accredited, Paris-Saclay university was placed fourteenth in ARWU by Shanghai Rankings in 2020. It is now one of the Europe’s biggest research universities.

Common objective

All countries have their unique legal framework for establishing universities, and therefore, while there are differences in the structure of HBNI, SOKENDAI, Paris-Saclay University, and Caltech, the objective is to benefit from synergies. It enables conducting academic research on focussed areas. It also enables pursuit of academic research and post-academic research in the same university, and results in faster deployment of results of research. Benefits can be seen from the growth and success of HBNI, which was ranked fourteenth a,pmg universities by NIRF-2020. Nature Index ranked HBNI at second position among all academic institutions in India during the period October 1, 2019 to 30 September 2020. Another example of a cluster-based university in India is the Academy of Scientific and Innovative Research established in 2011. Nature Index has ranked it at eighth position in India.

Different concepts

India needs to earnestly pursue this model. Institutions for clustering in a university can be selected based on different concepts; some examples could be institutes managed by a Department or a Ministry or a Public Trust, institutes located in close proximity, institutes pursuing similar objectives etc. Many industry associations have established research centres and more could be encouraged to do.

I will like to add a note of caution as well. In a cluster-based university, the ‘rewards system’ has to recognise all aspects of talent and all knowledge-based output. One may recall the advice given by P. B. Medawar to young scientists that “technicians are colleagues in a collaborative research”, and “despite their paper degrees”, young scientists have a lot to learn about research. This advice is more important today when complexity of experimental facilities is growing, and need not only competent technicians, but highly competent engineers, called scientific officers in national laboratories, for their design, construction, safe operation and maintenance. Scientific officers have deep insights about research capabilities of facilities.

For moving away from single-discipline institutions to multi-disciplinary universities, clustering is a promising model to achieve a critical mass in a university to invigorate research.

Scientists decode how Mars may have lost its atmosphere

[ad_1]

The researchers believe the study has important implications for the search for habitable exoplanets

Solar winds may have led to Mars losing its atmosphere, according to a computer simulation study which confirms the long held belief that planets need a protective magnetic field to block such harmful radiations in order to sustain life.

While factors like the existence of a moderately warm, moist atmosphere and liquid water determine whether a planet can host life, the study, published in the Monthly Notices of the Royal Astronomical Society, noted that the ability of planets to generate magnetic fields around them is an overlooked aspect.

According to the scientists, Arnab Basak and Dibyendu Nandi from the Indian Institutes of Science Education and Research (IISER) Kolkata, these magnetic fields enveloping planets can act like a protective umbrella, shielding the atmosphere from the super fast plasma winds of the Sun.

On the Earth, they said a geo-dynamo mechanism generates the planet’s protective magnetosphere — an invisible shield that stops the solar wind from eroding away our atmosphere.

In the current study, the scientists simulated two scenarios of the Red Planet — one considering a young Mars with its magnetosphere intact, and the other with the planet without this force field.

 

The simulations revealed that in the young Mars, the magnetosphere may have acted as a shield stopping the solar wind from coming too close to the planet’s atmosphere thus protecting it.

Without an intrinsic magnetosphere, the researchers said the solar wind magnetic field may have first draped around, and slipped past Mars, carrying bits of the planet’s atmosphere away, eventually eroding it completely. They said the findings confirm the belief that the magnetospheres around planets play a crucial role in determining their ability to sustain life.

Alternatively, planets that lose their magnetic field eventually become inhospitable with loss of their atmosphere, the scientists added.

The researchers believe the study has important implications for the search for habitable exoplanets via initiatives like NASA’s James Webb Space Telescope and ISRO’s ExoWorlds mission.
