Indian moms rank 3rd in foreign-born babies in US

October 27, 2016

Washington, Oct 27: Indian women rank third after their Mexican and Chinese peers among foreign mothers giving birth to children in the US with Asian immigrants increasingly accounting for a larger share, according to a latest study.

IndianAmong new foreign-born US mothers from the top 10 sending locations, those from India stand out for their low share of births outside marriage (one per cent), high rates of college degree attainment (87 per cent) and high annual family incomes (USD 104,500), the Pew Research Center said yesterday.

At the opposite end of the spectrum, new mothers from Honduras stand out for the high share who are unmarried (66 per cent), lack a high school diploma (51 per cent) and are living in poverty (49 per cent), it said.

"New moms from India stand out on both measures – almost nine-in-ten (87 per cent) have a bachelor's degree, and their annual median incomes top USD 100,000," said the study according to which after rising for decades, the share of US babies born to unmarried women has stabilised in recent years, driven by a sharp decline in births outside of marriage among foreign-born women, and a levelling off among US-born women.

According to the report, as per the latest statistics, in 2014 as many as 901,245 babies were born out of foreign-born mothers. Of these, Mexico accounted for the largest share of 287,052, followed by China (44,829) and India (43,364).

The 287,000 births to Mexican-born women in 2014 outnumbered all births to women from Asia, Europe, North America and Oceania combined.

China and India are the next most common origin countries – babies with mothers from these countries each account for five per cent of births to the foreign born.

It said none of the other countries comes even close to India when it comes to education and financial well off.

"The Indian case is particularly extreme – none of the other top sending countries come close in terms of the share of new moms with a bachelor's degree. Some six-in-ten new mothers from China and about half from the Philippines (52 per cent) have this credential. About a third of new mothers from Vietnam (35 per cent) have a bachelor's degree, while 18 per cent lack a high school diploma," the report said.

In terms of financial well-being, Indian-born new mothers have annual median family income more than twice as high (USD 104,500) as new US-born mothers (USD 51,200).

At the other end of the financial spectrum, just four per cent of Indian-born new mothers are in poverty, compared with 26 per cent of US-born mothers, it added.

New mothers from the Philippines, Vietnam and China are also relatively well-off. Those from the Philippines have annual incomes of about USD 75,000, those from Vietnam have incomes of about USD 70,000, and those from China have incomes of about USD 67,000, the study said.

Poverty rates for new mothers from these countries range from nine per cent to 14 per cent. Further more than nine-in- ten mothers of newborns from the Philippines and India are English-proficient, meaning they speak English "well" or better, it said.

"Just one per cent of new mothers from India are unmarried," the report said, adding that marriage is virtually universal among new mothers from India.

Births outside of marriage are also quite uncommon for new mothers from the other top sending countries in Asia: 11 per cent of new mothers from China are unmarried, as are 18 per cent from Vietnam and 19 per cent from the Philippines. The US average is 42 per cent.

Two-thirds of births to women from Honduras are to unmarried mothers. More than half of births to women from most other Latin American countries also occur outside of marriage, it said.

The exception is among women from Mexico: 47 per cent of births to Mexican immigrants occur outside of marriage, a rate slightly higher than among births to US-born mothers who are unmarried (42 per cent).

Pew said some 23 per cent of new mothers from India are 35 years old or older – far below the shares found among new mothers from the other major Asian sending countries.

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.

In a study conducted in 117 countries, researchers have found that the world is experiencing the most dramatic reduction in the seismic noise (the hum of vibrations in the planet's crust) in recorded history due to global COVID-19 lockdowns.

Measured by instruments called seismometers, seismic noise is caused by vibrations within the Earth, which travel like waves and the waves can be triggered by earthquakes, volcanoes, and bombs - but also by daily human activity like travel and industry.

This quiet period was likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, the study published in the journal Science, reported.

The new research, led by the Royal Observatory of Belgium and five other institutions around the world including Imperial College London (ICL), showed that the dampening of 'seismic noise' caused by humans was more pronounced in more densely populated areas.

"Our study uniquely highlights just how much human activities impact the solid Earth, and could let us see more clearly than ever what differentiates human and natural noise," said study co-author Stephen Hicks from ICL in the UK.

For the findings, the research team looked at seismic data from a global network of 268 seismic stations in 117 countries and found significant noise reductions compared to before any lockdown at 185 of those stations.

Researchers tracked the 'wave' of quietening between March and May as worldwide lockdown measures took hold.

The largest drops in vibrations were seen in the most densely populated areas, like Singapore and New York City, but drops were also seen in remote areas like Germany's the Black Forest and Rundu in Namibia.

Citizen-owned seismometers, which tend to measure more localised noise, noted large drops around universities and schools around Cornwall, UK and Boston, US - a drop in noise 20 per cent larger than seen during school holidays.

The findings showed that countries like Barbados, where lockdown coincided with the tourist season, saw a 50 per cent decrease in noise.

"The changes have also given us the opportunity to listen in to the Earth's natural vibrations without the distortions of human input," the study authors wrote.

Earlier in April, a study published in the journal Nature, reported at least a 30 per cent reduction in that amount of ambient human noise since lockdown began in Belgium.

U.S. electric vehicle maker Tesla Inc is "very close" to achieving level 5 autonomous driving technology, Chief Executive Elon Musk said on Thursday, referring to the capability to navigate roads without any driver input.

"I'm extremely confident that level 5 or essentially complete autonomy will happen and I think will happen very quickly," Musk said in remarks made via a video message at the opening of Shanghai's annual World Artificial Intelligence Conference (WAIC).

"I remain confident that we will have the basic functionality for level 5 autonomy complete this year."

Automakers and tech companies including Alphabet Inc Waymo and Uber Technologies are investing billions in the autonomous driving industry.

However industry insiders have said it would take time for the technology to get ready and public to trust autonomous vehicles fully.

The California-based automaker currently builds cars with an Autopilot driver-assistance system.

Tesla is also developing new heat-projection or cooling systems to enable more advanced computers in cars, Musk said.

Industry data showed Tesla sold nearly 15,000 China-made Model 3 sedans last month.

Tesla has become the highest-valued automaker as its shares surged to record highs and its market capitalisation overtook that of former front-runner Toyota Motors Corp.
