Boogaali | The Ugandan Company that’s Making Affordable & Sustainable Bicycles Out of Bamboo

It’s in his workshop, in the capital city of Kampala, that young Ugandan entrepreneur Noordin Kasoma designs bicycles made from bamboo. His company, Boogaali Bicycles limited, produces bicycles that are, not only affordable but also sustainable.

In an industry dominated by steel and aluminium, the use of bamboo is not as bizarre as it might seem. Kasoma says his bikes are strong, light and durable. They are also comfortable, he says.

“The bamboo itself tries to absorb the shocks that you are passing through, better than steel or aluminium.”

Bamboo frames aren’t uncommon in the cycling world. Noordin’s bicycles, however, come with a Ugandan spin: the joints are reinforced with bark cloth, a traditional clothing material extracted from the inner bark of the Mutuba tree.

In addition to being hand-crafted, the Boogaali bamboo bicycles are customized according to the cyclist’s needs and specifications.

Biscayne Bay fish kill is a warning sign, researcher says

Researchers set out Wednesday to survey Biscayne Bay between the 79th Street and Julia Tuttle Causeways, where dead fish were seen bobbing along the surface.

FIU’s autonomous surface vessel surveys Biscayne Bay near Morningside Park.

“It is an emergency. The bay is not in a good place right now,” said Piero Gardinali, a chemistry professor who is director of the institute’s Freshwater Resources Division. “It’s a warning sign more than anything else. People have been predicting that things like this could happen. I think it’s time for us to sit at the table and say ‘OK, let’s do something about it.’”

Researchers believe fish were killed when the bay’s saltwater became so hot, it could no longer retain oxygen in the amounts necessary for marine life to thrive.

They are using an autonomous surface vehicle equipped with sensors to measure temperature, dissolved oxygen, turbidity and chlorophyll, which can be an indicator for algae. What they find could provide more details on the health of the bay. The vessel allows researchers to collect more data over a larger area.

LinkedIn now has a newsroom of 65 journalists. It’s hiring more.

In Dan Roth’s dream world, members of LinkedIn, where he has served as editor in chief since 2011, would habitually read the LinkedIn Daily Rundown with their morning cup of coffee.

They’d then turn their attention to the site’s podcast or newsletter during their commute to work. When they get to their desks, they’d open LinkedIn.com on their browsers, where they can read from a carefully curated feed of professional and business news throughout their work day. Users who felt inspired by the content would share links on their own timeline. They’d check their notifications tab to see if others have engaged with the content they share. 

Who knows? They might even talk about one of LinkedIn’s articles at their next staff meeting.

This is Roth’s aspiration for LinkedIn’s 645 million members and for workers who have yet to use the site. He envisions LinkedIn as the perfect “utility” for professionals.

Surface Clean-Up Technology Won’t Solve Ocean Plastic Problem, According To Study

Clean-up devices that collect waste from the ocean surface won’t solve the plastic pollution problem, according to a new study. Researchers compared estimates of current and future plastic waste with the ability of floating clean-up devices to collect it – and found the impact of such devices was “very modest.”

However, river barriers could be more effective and – though they have no impact on plastic already in the oceans – they could reduce pollution “significantly” if used in tandem with surface clean-up technology.

Florida Aquarium Successfully Spawns Threatened Pillar Coral – Video Will Blow Your Mind!

For the second year in a row, scientists at The Florida Aquarium in Apollo Beach have successfully spawned threatened Atlantic pillar coral (Dendrogyra cylindrus) though lab-induced techniques. The scientific marvel occurred this week in a research laboratory as a part of a scientific spawning project called Project Coral.

The corals spawned at nearly exactly the same time as last year, at approximately 100 minutes after sunset on the second day after the full moon of August.

Zillow CEO: Real estate market is beginning ‘great reshuffling’ as people seek more space at home

The U.S. real estate market is beginning to show signs of a “great reshuffling,” as people relocate to homes with more privacy and space to ease working from home, Zillow CEO Rich Barton said on the company’s Q2 2020 earnings call this week. 

“I believe we are at the dawn of a great reshuffling,” Barton said. “I’m sure I don’t need to spell it out for you because we are all living it, spending an average of nine hours more per day at home. Zoom meetings are changing the way families think about space and privacy. Home offices are in high demand. Backyards are more desirable than parks and gyms. Work-from-home policies are eliminating the commute for many. There’s an endless list of considerations.”

Gone Phishing

Obinwanne Okeke was supposed to be a rags-to-riches Nigerian success story. Then the feds followed the money.

There he was, smiling on the cover of Forbes Africa magazine, dollar bills raining like confetti. It was June 2016, and Obinwanne Okeke, then 28, was on top of the world; he had just landed a coveted spot on the magazine’s prestigious 30 under 30 list of African entrepreneurs. In the article, he was one of many whiz kids described as “Africa’s bright young things.”

The 17th child of a polygamous father whose mother was the fourth wife, Okeke’s father died when he was 16, and his mother, a teacher, worked multiple jobs to put him and his siblings through school. Growing up in Ukpor, a village in southeastern Nigeria, was tough, and luxuries like sneakers or a Game Boy were hard to come by, he said in a 2018 BBC interview.

Turns out, Okeke had been involved in a string of sophisticated online scams since at least 2015 — including when he was gracing that glossy Forbes Africa cover. He was arrested at Dulles International Airport, Virginia, on August 6, 2019, for defrauding a company of nearly $11 million. He pleaded guilty to conspiracy to commit wire fraud on June 18, 2020, and now faces up to 20 years in prison at his sentencing in October.

Slocum Glider “Silbo” Circumnavigates the Atlantic Ocean | Science & Technology | News

Teledyne Marine’s Slocum G2 Glider named Silbo, manufactured by Teledyne Webb Research, has completed an over 4-year journey that circumnavigated the Atlantic Ocean in four legs, a first for an autonomous underwater vehicle (AUV).

In all, Silbo covered 22,744 km and spent roughly 1,273 days at sea.  

During Silbo’s incredible journey, it collected hurricane data, corrected current models, and provided close to 5000 CTD casts that aided metalogical forecasting. With partners from Rutgers University and its student base, UVI, PLOCAN, UGCLP, the Marine Institute, and others, Silbo also participated in the Challenger glider mission.

Silbo has been a test bed for many new engineering hardware and software features for both existing and next generation Slocum gliders. Recent legs have provided data on new battery configurations, advanced software, and techniques for piloting long endurance missions and minimizing biofouling.  Silbo’s accomplishments have been critical in the glider community’s understanding of techniques used to increase robot durations at sea.
