The mere presence of your mobile near you drains your brain!
This interesting experiment talks about how the position of our mobile phones impacts our cognitive ability.
The mere presence of one’s own smartphone may induce “brain drain” by occupying limited-capacity cognitive resources for purposes of attentional control. Because the same finite pool of attentional resources supports both attentional control and other cognitive processes, resources recruited to inhibit automatic attention to one’s phone are made unavailable for other tasks, and performance on these tasks will suffer. We differentiate between the orientation and allocation of attention and argue that the mere presence of smartphones may reduce the availability of attentional resources even when consumers are successful at controlling the conscious orientation of attention.

20,000 leagues under the sea
This article is a masterclass view of the world of undersea cables that fuel a large part of our online internet life.
These cables, only about as thick as a garden hose, are high-tech marvels. The fastest, the newly completed transatlantic cable called Amitié and funded by Microsoft, Meta and others, can carry 400 terabits of data per second. That's 400,000 times faster than your home broadband.
Such cables don't come cheap: A transatlantic cable costs about $250 million to $300 million to install.
Subsea cables are pretty tough, but every three days or so, one gets cut, TeleGeography said. The primary culprits, accounting for about 85% of cuts, are fishing equipment and anchors. Ships often will anchor themselves to ride out storms, but the storms push the ships and they drag their anchors.
Most of the other cuts are from the Earth itself, like earthquakes and mudslides. Tonga, whose single subsea cable connection was severed by a volcanic eruption, is another example.
Human-caused climate change is creating more extreme storms. In 2012, Hurricane Sandy cut 11 of the 12 high-capacity cables that connected the US and Europe.
Thoughts of the Week
"One of the hardest things to do in investing is to reverse your thinking. It is even more difficult to do after a specific approach has been profitable for a long time. The longer the period of successful thinking, the more important the reversal will be."

Video of the Week
Michael Oswald's film The Spider's Web reveals how at the demise of the empire, the City of London's financial interests created a web of secrecy jurisdictions that captured wealth from across the globe and hid it in a web of offshore islands. Today, up to half of global offshore wealth is hidden in British jurisdictions and Britain and its dependencies are the largest global players in the world of international finance.
