An international team of astronomers has conducted an astrometric and photometric wide-field study of the open cluster Messier 37. As a result, the researchers completed a comprehensive catalog of more than 200,000 sources in the field of Messier 37 and identified the hottest white dwarf candidate members of this cluster. The study was detailed in a paper published July 7 on arXiv.org.

Open clusters (OCs), formed from the same giant molecular cloud, are groups of stars loosely gravitationally bound to each other. So far, more than 1,000 of them have been discovered in the Milky Way, and scientists are still looking for more, hoping to find a variety of these stellar groupings. Studying OCs in detail could be crucial for improving our understanding of the formation and evolution of our galaxy.

Messier 37 (or M37, also known as NGC 2099) is the brightest and richest Galactic OC in the constellation Auriga, located at a distance of about 4,500 light years. The has a radius of at least 10 and a total mass of some 1,500 solar masses. The age of Messier 37 is estimated to be between 400 and 550 million years, while its metallicity is at a level of 0.02–0.08.

From endpoint fluorescence to melting curve analysis.

Today’s research on somatic, genetic and epigenetic variation in eukaryotic cells requires fast, accurate and cost-effective methods for screening large numbers of samples or loci in parallel. Variations identified by genomic sequencing or array studies need to be subsequently confirmed and validated.

Real-time PCR has become a well established technology for this purpose. The plate-based LightCycler 480 system offers a broad selection of methods and applications (Fig. 1).

Tech major Google is reportedly slowing down its hiring processes for the rest of 2022. According to a memo by CEO Sundar Pichai to employees, obtained by The Verge, Google will still support its “most important opportunities”, and focus on hiring engineering, technical and other critical roles.

Until now, Google has remained relatively immune to economic uncertainties, and in fact, its sister brand YouTube did well in Q4 2020 — first year of the Covid-19 pandemic. It was reported that its ad revenue hit $6.9 billion — up by 46% quarter-on-quarter. Pichai, in his memo, also highlights that the company hired approximately 10,000 employees in the second quarter of this year, and has a “number of commitments for Q3”, Pichai said in the memo adding that “Google will pause the hiring process for the rest of the year”.

“For the balance of 2022 and 2023, we’ll focus our hiring on engineering, technical and other critical roles, and make sure the great talent we do hire is aligned with our long-term priorities,” he reportedly wrote in the memo.

What seems like a sci-fi movie can be turned into reality if Japan’s technology is to be believed. Humans can travel across different planets on a train in the near future! Yes, you read that right. Japan has laid out plans in a bid to send humans to Mars and the Moon, according to The Weather Channel India.

Japan has made plans to build a glass habitat structure that would copy Earth’s gravity, atmosphere and topography to make us feel like home.

Researchers from Japan’s Kyoto University in collaboration with Kajima Construction are working on this plan that might shake up space travel, the Weather Channel reported. The researchers announced this last week in a press conference, the EurAsian Times reported.

“We know now that in the early years of the twentieth century this world was being watched closely by intelligence greater than man’s…across an immense ethereal gulf, minds that to our minds as ours are to the beasts in the jungle, intellects vast, cool and unsympathetic, regarded this earth with envious eyes and slowly and surely drew their plans against us.” So began actor Orson Welles’ chilling Mercury Theater radio performance on October 30, 1938 that Martians were invading, leading terrified listeners to believe that Earth was under attack by hostile aliens.

Welles’ chilling performance was a dramatization of the H.G. Wells science-fiction classic, “The War of the Worlds,” and was part of a weekly series of dramatic broadcasts created in collaboration with the Mercury Theatre on the Air for CBS, according to a transcript of the program.
