‘Anxiety Cells’ Identified in the Hippocampus

by Neuroscience News

Researchers reveal in mice, certain cells within the hippocampus fire when the animal is anxious and this triggers anxiety related behaviors to occur.

'We Heard the Bells: The Influenza of 1918'

Retropolis

The flu can kill tens of millions of people.
In 1918, that’s exactly what it did.

By Ashley Halsey III January 27 Email the author

The flu arrived as a great war raged in Europe, a conflict that would leave about 20 million people dead over four years.

In 1918, the flu would kill more than twice that number — and perhaps five times as many — in just 15 months. Though mostly forgotten, it has been called “the greatest medical holocaust in history.”

Experts believe between 50 and 100 million people were killed. More than two-thirds of them died in a single 10-week period in the autumn of 1918./.../

Human Development Reports

29 January 2018

By Asghar Zaidi, Professor of International Social Policy, University of Southampton

It is no secret that the world’s population is ageing. As fertility declines and life expectancy increases, the proportion of older people is projected to grow across the world. Therefore, it is increasingly important to develop metrics that assess the effectiveness of policies and programmes affecting older people.

The 2002 Madrid International Plan of Action on Ageing (MIPAA) is central to this measurement agenda and has three priority areas:

Older persons and development (in particular social protection);
Advancing health and well-being into old age; and
Ensuring enabling and supportive environments.

Fifteen years later, it is timely to assess the effectiveness of the Plan and indeed review it is a theme of this week’s UN Commission for Social Development.

The MIPAA started with great promise as one of the only international policy frameworks to focus on older people. The latest UN review of MIPAA shows that despite progress, its implementation remains uneven across both countries and the three priority areas. Major constraints include lack of resources, political will and data.

In such introspection, another critical question is how the MIPAA stays relevant when the international community is committed instead to its newest and most comprehensive policy framework to date, the 2030 Agenda for Sustainable Development.

FREE TECH TOOLS & WEBSITES

10 FREE TECH TOOLS & WEBSITES EVERY TEACHER SHOULD KNOW ABOUT

Confession: I was a late tech adopter.

I didn’t own a computer until I was in college. I couldn’t record on the VCR, and I didn’t have a smartphone until about 2009. As a new teacher, I felt comfortable with PowerPoint and Word, yet I rarely explored any other tech tools.

I felt out of my league when it came to tech, and chalked it up as something the younger, more tech-savvy members of the staff would do. My mindset changed as the number of devices available in our school grew, as well as my observations of the ease with which my students could navigate and create with their laptops. They inspired me to try more tech.

Several years later, as I teach my global studies course and my students explore the world in real time through their devices, I couldn’t imagine not being a to take advantage of this technology. There are free tools that are easy to use—even for the tech novice.

Here are my picks for the top 10 tech tools and websites every teacher should know about!

JAN PIETRZAK has just one demand. He’s not fussy about the design of the centennial arch with which he wants to mark the Polish victory over the Bolshevik armies in 1920. But he does insist that it must be taller than the 237-metre (778-foot) Palace of Culture and Science, given to the Polish nation by Stalin.
Mr Pietrzak is a gruff old man with white hair and a fine, bushy moustache, a popular entertainer best known for a patriotic song that became an anthem for Solidarity in the 1980s. Although the Warsaw authorities have balked at his dream of a triumphal arch, he has the backing of the Law and Justice party, which forms the national government. It will be a symbol, he says: “Young people …will know that Poland was victorious—like Trafalgar Square.”

Fotos, vídeos e aplicativos que não são usados são os conteúdos mais frequentes entre os usuários que não querem apagá-los por medo de perdê-los. Batizados de “acumuladores digitais”, estas pessoas estão acostumadas a guardar materiais e conteúdos de todos os tipos em seus dispositivos sem discriminar quão importantes eles são. Pesquisa desenvolvida pela Western Digital detectou características e hábitos mais frequentes entre esse tipo de usuário.

O avanço da tecnologia e sua incorporação na vida cotidiana têm gerado um apego cada vez mais forte, em especial pelos celulares, revela o levantamento. De acordo com o estudo, 43% dos participantes confessam que têm medo de perder ou ficar longe de seus smartphones por muito tempo.

World Economies 2017

Every One of the World’s Big Economies Is Now Growing

By PETER S. GOODMANJAN. 27, 2018

Growth Across the Globe

For the first time since the financial crisis a decade ago, all of the world’s major economies are growing.

LONDON — A decade after the world descended into a devastating economic crisis, a key marker of revival has finally been achieved. Every major economy on earth is expanding at once, a synchronous wave of growth that is creating jobs, lifting fortunes and tempering fears of popular discontent.

No tidy, all-encompassing narrative explains how the world has finally escaped the global downturn. The United States has been propelled by government spending unleashed during the previous administration, plus a recent $1.5 trillion shot of tax cuts. Europe has finally felt the effects of cheap money pumped out by its central bank./.../
