The scoop on UAE’s artificial rain: Did cloud seeding drown Dubai?

Posted by in category: geoengineering

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 detected for the first time

Posted by in categories: materials, quantum physics

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.

Scientists are one step closer to knowing the mass of ghostly neutrinos — possibly paving the way to new physics

Posted by in category: particle physics

By precisely measuring the mass of neutrinos — ghostly particles that stream through your body by the billions each second — physicists could find some glaring holes in the Standard Model of particle physics. A new experiment has taken them one step closer.

Spider-like robot could crawl into Mars’ congested caves to hunt life

Posted by in categories: robotics/AI, space

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.
