US life expectancy drops for first time since AIDS crisis peak

December 8, 2016

Miami, Dec 8: Life expectancy in the United States dropped last year for the first time since the peak of the HIV/AIDS crisis more than 20 years ago, as deaths rose from nearly every major cause, federal data showed today.

aids-dayThe total US population's life expectancy in 2015 was 78.8 years, a decrease of 0.1 year from 2014, said the report by the National Center for Health Statistics.

Deaths from eight of the top 10 causes mounted, including spikes in accidental deaths among children and deaths from Alzheimer's disease in the elderly.

The report did not delve into the reasons for the across-the-board decline in life expectancy from birth, but experts pointed to economic struggles, drug addiction and the increasing burden of dementia on an ageing population as potential factors.

Across the nation, 86,212 more people died in 2015 than a year earlier.

"This is unusual," said lead author Jiaquan Xu, an epidemiologist at the NCHS, which is part of the US Centers for Disease Control and Prevention."2015 is kind of different from every year," Xu told AFP.

It "looks like much more death than we have seen in the last few years." The last time life expectancies at birth dropped for the total US population was in 1993, a year when the deaths from AIDS reached a peak in the United States, compounded by a bad flu year that resulted in more flu and pneumonia deaths, he said.

Homicide and accidental death rates also went up that year.For 2015, the data also showed a 1.2 per cent increase in the death rate for the total population, and this "rose significantly for the first time since 1999," noted the report.

For US men, life expectancy dropped 0.2 years from 76.5 years in 2014 to 76.3 years in 2015.

For US women, life expectancy decreased 0.1 year to 81.2 years in 2015.The overall downward trend in America stands in sharp contrast to the situation worldwide, where global life expectancy has increased five years from 2000 to 2015, according to the World Health Organization.

Women in Japan currently have the longest average lifespan at 86.8 years, while men in Switzerland can anticipate 81.3 years.Sierra Leone has the lowest life expectancy, with women at 50.8 years and men at 49.3.

In the United States, life expectancy has stagnated nationwide in recent years. Federal data from 2014 showed a slight downturn in life expectancy for white people, which experts said could be due to rising drug abuse particularly the prescription painkiller epidemic and poverty. But this year, there was no single cause.

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.

The World Health Organisation (WHO) on Saturday launched a Health Alert on WhatsApp where over 1.5 billion users can ask questions and they will be provided with reliable information about new coronavirus 24/7.

This will also serve government decision-makers by providing the latest numbers and situation reports, WhatsApp said in a statement.

To contact the WHO Health Alert, save the number +41 79 893 1892 in phone contacts, and then simply text the word 'Hi' in a WhatsApp message to get started.

The service responds to a series of prompts and will be updated daily with the latest information.

"You can also visit the WhatsApp Coronavirus Information Hub at whatsapp.com/coronavirus," and click on the WHO link on the homepage to open up a chat with the WHO Health Alert if you have WhatsApp installed," said the micro-blogging platform.

The WHO Health Alert will provide official information on topics such as how to protect yourself from infection, travel advice, and debunking new coronavirus myths.

The service is initially launching in English but will be available in all six languages within the coming weeks (English, Arabic, Chinese, French, Russian and Spanish.)

"Digital technology gives us an unprecedented opportunity for vital health information to go viral and spread faster than the pandemic. We are proud to have partners like Facebook and WhatsApp, that are supporting us in reaching billions of people with important health information," said Dr Tedros Adhanom Ghebreyesus, Director-General of the WHO.

The WHO Health Alert is the latest official NGO or government helpline to become available on WhatsApp, joining the Singapore Government, The Israel Ministry of Health, the South Africa Department of Health, and KOMINFO Indonesia.

Earlier this week, WhatsApp, in partnership with the World Health Organization, UNICEF, and UNDP, launched the WhatsApp Coronavirus Information Hub. The hub offers general tips and resources for users around the world to reduce the spread of rumours and connect with accurate health information.

WhatsApp also announced a $1 million grant to the International Fact Checking Network to support fact-checking for the #CoronaVirusFacts Alliance.

Facebook on Monday launched a new consumer marketing campaign in India titled 'More Together'. India is the first country in the Asia Pacific region where such a campaign is being rolled out.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

"India is at the heart of Facebook and one of our focus areas this year is to tell the exciting story of a service that is deeply embedded in the fabric of India," said Ajit Mohan, Vice President and Managing Director, Facebook India.

The campaign would have multiple campaigns over the next few weeks in eight languages and the one will be set in the context of Holi.

Facebook in 2019 introduced a new company logo to further distinguish the company from the Facebook app.

The company recently announced the appointment of Avinash Pant as the Marketing Director for India operations, to drive the consumer marketing efforts across the family of apps.
