RSS chief pays tribute to Gauri Lankesh, Dharam Singh

Chamarajanagar, Jan 3: The residents of Galipura layout in Chamarajanagar city boycotted the annual Community Based Survey (CBS), conducted by the Health and Family Welfare department, mistaking it to be the National Register of Citizens (NRC).

Majority of the residents in the layout belong to Muslim community. The people, who mistook CBS to the NRC survey, got into arguments with the Asha workers, who were given the responsibility of collecting information. They even tore the forms into pieces and vent their ire.

The Health Department conducts CBS every year in the urban areas and collects all details including Aadhaar number, residential address, details of family members, health problems and others.

Fifteen Asha workers were deputed for the survey in the layout. A few youths started questioning them alleging it to be an NRC survey and started arguing with them.
Tahsildar Mahesh, District Health and Family Welfare Officer Dr N C Ravi, with the help of Muslim leaders cleared the confusion. The community leaders assured of explaining it to the residents and extend cooperation to the survey.

Udupi, July 17: An Indian expatriate from coastal Karnataka who was working in Kuwait passed away in a hospital in the oil-rich country reportedly due to covid-19.

Sheikh Mohammed Syed (54) was a native of Kharvi in Kundapura taluk of Udupi district. He is survived by his mother, wife and three daughters. 

An ex athletic champion from Bhandarkars' Arts & Science College, he was a well-known Volleyball and Kabaddi player in Kundapur.  He was associated with many sports associations in Udupi. 

An employee of KRH firm, he was hospitalized in Kuwait three weeks ago due to ill health. He was tested positive for covid-19.

He breathed his last yesterday without responding to any treatment. Final rites were held in Kuwait. 

Prior to migrating to Kuwait, he had worked in United Arab Emirates for several years. A sports enthusiast, he had trained many athletes in Udupi.

Washington DC, Jun 8: Astronomers acting on a hunch have likely resolved a mystery about young, still-forming stars and regions rich in organic molecules closely surrounding some of them.

They used the National Science Foundation's Karl G Jansky Very Large Array (VLA) to reveal one such region that previously had eluded detection and that revelation answered a longstanding question.

The regions around the young protostars contain complex organic molecules which can further combine into prebiotic molecules that are the first steps on the road to life.

The regions, dubbed "hot corinos" by astronomers, are typically about the size of our solar system and are much warmer than their surroundings, though still quite cold by terrestrial standards.

The first hot corino was discovered in 2003 and only about a dozen have been found so far. Most of these are in binary systems, with two protostars forming simultaneously.

Astronomers have been puzzled by the fact that, in some of these binary systems, they found evidence for a hot corino around one of the protostars but not the other.

"Since the two stars are forming from the same molecular cloud and at the same time, it seemed strange that one would be surrounded by a dense region of complex organic molecules and the other wouldn't," said Cecilia Ceccarelli, of the Institute for Planetary Sciences and Astrophysics at the University of Grenoble (IPAG) in France.

The complex organic molecules were found by detecting specific radio frequencies, called spectral lines, emitted by the molecules. Those characteristic radio frequencies serve as "fingerprints" to identify the chemicals.

The astronomers noted that all the chemicals found in hot corinos had been found by detecting these "fingerprints" at radio frequencies corresponding to wavelengths of only a few millimetres.

"We know that dust blocks those wavelengths, so we decided to look for evidence of these chemicals at longer wavelengths that can easily pass through dust," said Claire Chandler of the National Radio Astronomy Observatory, and principal investigator on the project.

"It struck us that dust might be what was preventing us from detecting the molecules in one of the twin protostars," added Chandler.

The astronomers used the VLA to observe a pair of protostars called IRAS 4A, in a star-forming region about 1,000 light-years from Earth. They observed the pair at wavelengths of centimetres.

At those wavelengths, they sought radio emissions from methanol, CH3OH (wood alcohol, not for drinking). This was a pair in which one protostar clearly had a hot corino and the other did not, as seen using the much shorter wavelengths.

The result confirmed their hunch. "With the VLA, both protostars showed strong evidence of methanol surrounding them. This means that both protostars have hot corinos. The reason we did not see the one at shorter wavelengths was because of dust," said Marta de Simone, a graduate student at IPAG who led the data analysis for this object.

The astronomers cautioned that while both hot corinos now are known to contain methanol, there still may be some chemical differences between them. That, they said, can be settled by looking for other molecules at wavelengths not obscured by dust.

"This result tells us that using centimetre radio wavelengths is necessary to properly study hot corinos," Claudio Codella of Arcetri Astrophysical Observatory in Florence, Italy, said.

"In the future, planned new telescopes such as the next-generation VLA and SKA, will be very important to understanding these objects," added Codella.
