Digital Nomads: The Solo Wanderer traveling across Africa to find what connects us | TechCabal

digital nomads: the solo wanderer traveling across africa to find what connects us | techcabal


In 2017, Katchie Nzama, more popularly known as The Solo Wanderer, backpacked from Africa’s Northernmost point to its Southernmost point on her own. It took her six months to travel across 21 countries in a trip she tagged #BreakingBorders.

She has since expanded her travel repertoire, having visited 35 of Africa’s 54 countries.  

Her life sometimes sounds like one big vacation and she has stories for days. She talks about the beauty of Tunisia and how the country hasn’t recovered from the Arab Spring. In another breath, she talks about being in Sierra Leone during the 2017 mudslide.

Yet, way before all these travels, she talks about growing up in South Africa.

“I grew up in Johannesburg and I always traveled growing up. But my curiosity about traveling through Africa started in high school when a Nigerian student joined our class during the year. He spoke in a different accent from all of us and I was so curious about Nigeria where he came from.”

But there was no dramatic punt across the continent yet. Instead, after high school, Nzama worked at an event planning company as a marketing coordinator.

“I hated working in an office, it was the most horrible life …



Opinion: The U.S. unraveling of science insulation from politics

opinion: the u.s. unraveling of science insulation from politics


With myriad suggestions for addressing the coronavirus pandemic, there is a common refrain: Trust the scientists.But some scientific voice can be found to support nearly any assertion. Each year, nearly 2.5 million new scientific papers are published in about 30,000 journals. We can’t make policy based on single studies or the opinion of a single scientist.
There are legitimate disagreements about whether the virus is spread by droplets or airborne mists. There is evidence that opening schools will either harm or not harm small children. We don’t know for certain if the protection offered by cloth masks is similar to N-95s or how far we need to distance from each other. Knowing whom to trust is challenging.
Until very recently, the United States was the world’s exemplar in making sense from divergent scientific opinions. More than 150 years ago, President Abraham Lincoln and Congress created the National Academy of Sciences to provide independent, objective advice on science and technology. In the 1940s, engineer Vannevar Bush persuaded President Franklin Roosevelt that science was the ticket to a successful war effort and to a continuing strong economy.
Starting in 1933, U.S. presidents, Republicans and Democrats alike, made extensive use of …

A Crazier Crazy Straw for Cutting-Edge Science

a crazier crazy straw for cutting-edge science


In this artist’s conception, data from the small angle neutron scattering (SANS) experiment at the NIST Center for Neutron Research (NCNR) form a colorful backdrop to transparent spheres representing part of a worm-like micelle, a tiny structure often found in soaps. Higher-intensity neutron scattering (red regions) indicates that the micelles are aligning strongly with the direction of flow through the NCNR’s capillary rheoSANS device, lining up like toothpicks in a tube. The micelles are one of many substances whose properties under extreme flow conditions could become better understood with the new research tool. Credit: R. Murphy/NIST

What do the loopy straws that children like to sip drinks through have in common with cutting-edge science? Ask Ryan Murphy and his colleagues at the National Institute of Standards and Technology (NIST), where the team has thought up a creative way to explore the properties of fluids under extreme conditions.
The team invented a device that can push fluids through a narrow tube at the velocity of a car hurtling down a rural interstate — about 110 km per hour. This might not sound overly fast to a road tripper, but the …

PaleoanthropologyAndrew M. SugdenThe Border Cave site in the KwaZulu-Natal region of South Africa has been a rich source of archaeological knowledge about Stone Age humans because of its well-preserved stratigraphic record. Wadley et al. now report the discovery of grass bedding in Border Cave, dated to approximately 200,000 years ago. The bedding, identified with a range of microscopic and spectroscopic techniques, was mingled with layers of ash. It also incorporated debris from lithics, burned bone, and rounded ochre grains, all of which were of clear anthropogenic origin. The authors speculate that the ash may have been deliberately used in bedding to inhibit the movement of ticks and other arthropod irritants. These discoveries extend the record of deliberate construction of plant bedding by at least 100,000 years.Science, this issue p. 863

This story was originally published August 6, 2020 by the Thomson Reuters Foundation.


MILAN, Aug 6 (Thomson Reuters Foundation) – Offering sunny beaches, cheap living and low infection rates, countries are competing for a new generation of remote workers in a bid to ride out the pandemic and make up for lost visitors.

From Estonia to Barbados, nations have launched visa regimes aimed at wooing “digital nomads” to bolster their economies, chasing the sort of people who mix work with travel and can set up shop any place with an internet connection.

“Work from Paradise,” boasts the web page of Barbados’ 12-month Welcome Stamp Visa, which launched in July, allowing remote workers to relocate to the Caribbean island for one year.

“Our new … (visa) allows you to … work from one of the world’s most beloved tourism destinations,” the country’s Prime Minster, Mia Mottley, wrote in a welcome message on the page.

Interest in “digital nomadism” is set to …

michael soulé (1936–2020)


Michael Soulé, widely credited with starting the field of conservation biology, died on 17 June at age 84. Michael’s research laid the intellectual groundwork for a new avenue of study, and he cofounded the Society for Conservation Biology in 1985 to ensure that the nascent field had the resources and organization to address the critical environmental issues we face today. Michael’s vision of a better world, in which nature holds a central place, has inspired scientists and nature enthusiasts across the globe.Born on 28 May 1936, Michael grew up in San Diego, California. His free-ranging childhood, spent exploring tide pools and collecting abalones and lobsters, sparked his lifelong love of natural history and helped shape his interest in ecosystems. Michael obtained his undergraduate degree in biology at San Diego State College and his Ph.D. in biology in 1964 from Stanford University in Stanford, California.After joining the biology faculty at the University of California (UC) San Diego in 1967, Michael became troubled by the rapid loss of natural habitats in Southern California. He resigned from the university in 1979 to become director of the Kuroda Institute for the Study of Buddhism at the Zen Center of Los Angeles. In 1984, he returned to academia, first teaching at …

In the late 1400s, a terrifying disease erupted in Europe, leaving victims with bursting boils and rotting flesh. The syphilis epidemic raged across the continent, killing up to 5 million people. For centuries, historians, and archaeologists have debated the origin of the disease, with some blaming Christopher Columbus and his crew for bringing it back from the Americas. Now, using DNA of the pathogen extracted from the remains of nine Europeans, researchers have found evidence that the epidemic was homegrown: diverse syphilis strains were circulating in Europe, perhaps decades before Columbus’s voyages.

Today, syphilis and other conditions caused by the same bacterium, Treponema pallidum, such as yaws and bejel, are making a comeback, with millions of people infected every year. “These diseases are not just a problem of the past,” says Verena Schuenemann, a palaeogeneticist at the University of Zürich and co-author of the new study. By understanding when and where T. pallidum originated, and how it has evolved, she says, researchers can learn how it might behave in the future and be prepared to treat …

To the Mathematician Eugenia Cheng, There’s No Gap Between Art and Science

to the mathematician eugenia cheng, there’s no gap between art and science


“The boundaries between subjects are really artificial constructs,” says the mathematician and author, whose new book is “X+Y: A Mathematician’s Manifesto for Rethinking Gender.” “Like the boundaries between colors in a rainbow.”What’s the last great book you read?“Notes From a Young Black Chef: A Memoir,” by Kwame Onwuachi and Joshua David Stein. I think it’s really important to read first person accounts of the way Black people are disadvantaged by the structures of American society, as well as by systems and by individuals. This memoir is bracing to those of us privileged to have been protected by our ethnicity or our relative affluence. In the end, however, it’s a deeply inspiring story from someone who was almost destroyed by the disadvantages piled onto them by society but who managed to rise up and then work to help others rise too.Are there any classic novels that you only recently read for the first time?“Yevgeny Onegin” (in translation). I’ve known and loved the opera since I was a teenager, but the only thing I read was many articles about the difficulties of translating it, and so shied away from reading it in …

2019-2020 Leadership Alexandria Class Volunteers with Habitat for Humanity of Douglas County

2019-2020 leadership alexandria class volunteers with habitat for humanity of douglas county


The Alexandria Lakes Area Chamber of Commerce 2019-2020 Leadership Alexandria class assisted in a variety of projects for a Habitat for Humanity Homebuyer this year. This was done in the Alexandria area on Monday, July 13 and Monday, July 27.The Leadership Alexandria program kicks off each October with a two-day retreat, where participants learn more about their personality style, about working with different personality styles and about other key leadership traits. The class then comes together one full day each month from November to May to learn about the area’s history, the local business community, local government and more. Throughout the year the class is given the opportunity to choose one community service project that they will complete after graduation. This year’s class chose to volunteer with Habitat for Humanity.Due to COVID-19, the 25-member class was unable to work together in this effort and instead broke into four smaller groups that volunteered on two different build days. Projects consisted of a variety of things including putting up poly, taping around electrical units, putting on siding and building picnic tables. The 2019-2020 Leadership Alexandria class still has two sessions to complete prior to graduation. These were postponed due to …
