Bengaluru, Jul 16: Amid difficulties being faced by COVID-19 patients in getting beds, the Karnataka government on Wednesday made bed allocation display board mandatory in all hospitals registered under Karnataka Private Medical Establishment (KPME).

"It is made mandatory that all hospitals registered under KPME in Karnataka State should display at the reception counter, a bed allocation display board," a notification issued by the state government read.

"It should display the name of the hospital, the total number of beds (as per of KPME registration) and the total number of beds allocated for COVID-19 patients referred by Bruhat Bengaluru Mahanagara Palike (BBMP)," it said.

The notification further stressed that the data must corroborate with the data of the central bed allocation system of BBMP. The display board should be arranged by July 16.

Non-compliance to the order issued by the state government will attract punishment under relevant sections of the Disaster Management Act 2005 and Indian Penal Code, the order read.

The state government on June 23 issued a notification making it mandatory to reserve 50 per cent of the beds in private hospitals to treat COVID-19 patients referred by public health authorities.

Mangaluru, Mar 29: Dakshina Kannada Co-operative Milk Producers’ Union Limited in a statement announced that their milk collection centres across Dakshina Kannada and Udupi districts will be closed on March 29 and 30.

Due to a shortage of storage space with them, the Union has decided to stop collecting milk on these two days, according to the statement issued here on Saturday.

The sale/retail of milk and milk products won’t be affected in these two days.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.
