Since this news was published, users have taken to social media to share images and videos of the flooding and placed the blame on the seeding exercises.

While it is easy to correlate the two incidents and blame the flooding on the seeding exercises, a deeper look at the reality tells a different story.

Cloud seeding isn’t new to Dubai. The Bloomberg report states that the technique has been used since 2002 and has never shown such disastrous outcomes in the previous two decades. One can be certain that the seeding experiments have not gone wrong on this occasion since Dubai conducts about 300 such operations every year. The NCM also clarified that it did not do any cloud seeding on the day the storm struck.

Quantum Barkhausen noise, which arises from the cooperative quantum tunnelling of a huge number of magnetic spins, has been observed for the first time and may be the largest macroscopic quantum phenomena ever seen.

Researchers in the US and Canada have detected an effect known as quantum Barkhausen noise for the first time. The effect, which comes about thanks to the cooperative quantum tunnelling of a huge number of magnetic spins, may be the largest macroscopic quantum phenomena yet observed in the laboratory.

In the presence of a magnetic field, electron spins (or magnetic moments) in a ferromagnetic material all line up in the same direction – but not all at once. Instead, alignment occurs piecemeal, with different regions, or domains, falling into line at different times. These domains influence each other in a way that can be likened to an avalanche. Just as one clump of snow pushes on neighbouring clumps until the entire mass comes tumbling down, so does alignment spread through the domains until all spins point in the same direction.

Saddened by the news of Prof. Daniel Dennett’s passing. a brilliant philosopher with with such great influence in cognitive science. It’s such a great loss.

Daniel Dennett, professor emeritus of philosophy at Tufts University, well-known for his work in philosophy of mind and a wide range of other philosophical areas, has died.

Professor Dennett wrote extensively about issues related to philosophy of mind and cognitive science, especially consciousness. He is also recognized as having made significant contributions to the concept of intentionality and debates on free will. Some of Professor Dennett’s books include Content and Consciousness (1969), Brainstorms: Philosophical Essays on Mind and Psychology (1981), The Intentional Stance (1987), Consciousness Explained (1992), Darwin’s Dangerous Idea (1995), Breaking the Spell (2006), and From Bacteria to Bach and Back: The Evolution of Minds (2017). He published a memoir last year entitled I’ve Been Thinking. There are also several books about him and his ideas. You can learn more about his work here.

ReachBot is inspired by the movement of the Harvestman spider, also known as a daddy-long-legs. The current model boasts a small body and long, extendable legs equipped with grippers. Moreover, the booms will allow the robot to move ahead.

These appendages allow ReachBot to navigate through the narrow passages of Martian caves to hunt for signs of life and other key resources, like water. The multiple extendable boom limbs have a three-finger gripper that clutches onto the rocks and uses them as anchor points.
