Scientists declaring climate emergency is 'an exercise in advocacy'

  Scientists declaring climate emergency is 'an exercise in advocacy' Sky News host Chris Kenny says only a fraction of the scientific community have signed a petition to declare a climate emergency, and therefore it is merely “an exercise in advocacy”. Mr Kenny’s comments come after a group of scientists rallied and put a declaration together, joining a global push to call for a climate emergency. The Sky News host said 11,000 is a “significant number of signatures” but said it does need to be kept “in perspective”.“This is 11,000 scientists from all sorts of areas from around the world, effectively signing a petition,” he said.

If you’re trying to build something that won’t sink, making it out of metal seems like a terrible idea.

We make boats and ships out of metal because it’s sturdy and lasts a long time, but it weighs a lot and, if something goes wrong, there’s nothing stopping it from sinking to the bottom.

Researchers from the University of Rochester have come up with a potential solution.

It’s a metal that absolutely hates water, strongly repelling it and creating pockets of air that allow the metal to float under just about any circumstance.

Researchers have created a metallic structure that is so hydrophobic, it refuses to sink - no matter how often it is forced into water or how much it is damaged or punctured. Possible applications include unsinkable ships and wearable flotation devices that will still float after being punctured.

Scientists here on Earth have been experimenting with analogs of Martian soil to determine what might grow there. There are a number of candidates, including potatoes, and it’s entirely possible that we’ll one day be growing crops somewhere other than Scientists invented metal that refuses to sink .

Its inventors believe it could revolutionize ship design and create truly unsinkable boats.

The secret is a special pattern that is etched into the surface that traps air and prevents water from making clean contact, pushing it away.

The team says this “superhydrophobic” etching technique was inspired by the natural world. The bodies of fire ants are hydrophobic, and spiders that craft underwater webs use their bodies to trap air and carry it with them beneath the surface.

“The key insight is that multifaceted superhydrophobic (SH) surfaces can trap a large air volume, which points towards the possibility of using SH surfaces to create buoyant devices,” the researchers explain in a new research paper.

To demonstrate how the metal behaves, the researchers devised an experiment with two seemingly identical metal discs.

Gold Coast Deputy Mayor refuses to comment on donations 'error' following tribunal

  Gold Coast Deputy Mayor refuses to comment on donations 'error' following tribunal Gold Coast Deputy Mayor Donna Gates refuses to comment on a ruling handed down by the Office of the Independent Assessor made public this week. Gold Coast Deputy Mayor Donna Gates has refused to comment on a ruling handed down by the Councillor Conduct Tribunal and made public this week. Cr Gates was re-elected unopposed in 2016 and the tribunal said information she subsequently submitted for a register of interests was misleading.

What makes the robots appear so incredibly lifelike is their fluidity of movement. They twist and turn and hop around in a manner that mirrors four-legged animals, and knowing that these little fellas are metal and wires instead of flesh and bone fills you with an even mix of wonder and dread.

Scientists invented metal that refuses to sink .

One of the disks is “normal” metal, while the other is the same material with the special etching technique applied. As you can see in the video, the superhydrophobic metal disc refuses to sink, even when pushed deep beneath the water.

Perhaps even more important for real-world use cases, the metal retains its water-repelling properties even when damaged.

The researchers drilled several holes in the disc, revealing that it still floated the surface even when its structural integrity was compromised.

This proves that metal etched in such a way could be useful in the manufacturing of boats and ships, potentially giving them real “unsinkable” properties and allowing them to remain afloat even when damaged.

'Mickey Mouse' and other fake scientists revealed as signatories to massive climate petition .
Daily Telegraph Opinion Editor James Morrow says the petition calling for the declaration of a climate emergency is signed by ‘climate cultists’ trying to enforce ‘their own socialist ideals’. Mr Morrow’s comments come after it was revealed that the 11,000 signatures touted in the media as proof there is a climate emergency may have been hijacked by a few fake signatories - like Mickey Mouse from the Mickey Mouse School of the Blind and Zoology professor Araminta Aardvark from the University of Neasden.
