Godstone sinkhole to be investigated with 3D maps, says council
She said: "What I have seen is information that says the borehole testing is delayed, and they're going to use less intrusive testing methods and survey methods."The less intrusive testing methods will be used first."One of the alternative methods that may be used is LiDar - which stands for Light Detection and Ranging.It is a remote sensing technique which uses lasers to measure distances and create 3D maps, Ms Sayer added.The technology has been around since the 1970s when it was used in meteorology, but is now used by autonomous vehicles to sense surroundings.
A source from Surrey County Council, whose highways department is responsible for the investigation, said equipment will arrive 26 February. He said: "We're waiting for some specialist equipment to arrive on site to carry out further comprehensive assessment to ensure any stability and repair work is safe and designed properly."Tandridge District Council said it will be hosting a public meeting at St Nicholas Youth Centre on Tuesday evening to address concerns from residents and business owners.

World's first portable mosquito ‘air defence' blasts biters with lasers to neutralise them on its own, inventor claims
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A MOSQUITO-busting laser that can supposedly kill up to 30 mozzies a second has been proposed by a Chinese firm. The gadget, called Photon Matrix, is claimed to be able to detect the mosquito, as well as its angle and size, within just three milliseconds.

The laser will allegedly scan its surroundings to avoid firing at larger objects such as people and pets. However, it is still a prototype - so it is unclear if it can really do the job just yet. The company expects to make its first deliveries of the product in October this year.

According to its inventor, Jim Wong from Changzhou, China, it is a 'prototype of the first mosquito air defence system capable of identifying and neutralizing mosquitoes using high-specification LiDAR technology.' Photon Matrix can detect objects that are flying at a top speed of 3.3 feet (one meter) per second. That parameter is good news for house flies, which will only be fatally hit by it if they are flying really slowly. 4 bitten-worlds-first-portable-mosquito-1008450849 Credit: Photon Matrix Mosquitoes, however, typically fly at a much slower pace than house flies. So it weeds out the nasty critters, without taking out harmless house flies. 'I was quoted £10,000 for a garden renovation but did it MYSELF for £1,000 using ChatGPT to show my kids what single mums can do' To this end, Wong says the mini laser weapon will not harm humans or pets, and is safe for use indoors. Wong is raising money for the project on crowdfunding site Indiegogo, and the campaign has already met the its initial goal, Interesting Engineering reported. Mosquitoes are responsible for over 700,000 deaths annual due to the diseases they spread - including Malaria, Dengue, Chikungunya, and Encephalitis. According to the Indiegogo page for the device, the basic edition of Photon Matrix has a waterproof design and can be installed easily. This leaves it best placed to sit by water, which tends to attract mosquitoes - especially in summer. It can also be powered by a simple power bank or through a portable power station, according to the listing. The compact device on display is said to have a range of 9.84 feet (3 meters) for the basic version. However, the pro version can detect mozzies up to 19.6 feet (6 meters) away, according to the inventor. Both the basic and pro versions have a scan angle of 90 degrees. While the basic version is on offer for $468 (£345), the pro version is available for $668 (£492) - though these are early bird prices. 4 Man while applying insect repellent on his hand.

‘Gateway to the underworld' discovered beneath ancient temple
Hiyah Zaidi Published May 27, 2025 4:46pm Updated May 27, 2025 4:46pm Link is copied Comments An ancient pyramid in Mexico was found to contain liquid mercury and experts believe it may have been considered as a 'gateway to the underworld'. It's thought that this finding could suggest the existence of a king's tomb or a ritual chamber below one of the most ancient cities of the Americas. The Quetzalcoatl temple – also known as the Feathered Serpent Pyramid – sits in the ancient city of Teotihuacan, Mexico, and is thought to have been built around 1,800 and 1,900 years ago (Picture: Yasemin Kalyoncuoglu/Anadolu via Getty) It remained mysterious for many years, until in 2015, when researchers discovered a large amount of liquid mercury, which they suggested meant the structure was used to 'look into the supernatural world'. Mexican researcher Dr Sergio Gómez had spent six years slowly excavating the tunnel, which was unsealed in 2003 after 1,800 years (Picture: REUTERS/Henry Romero) In the excavation, they found three chambers at the end of a 300ft tunnel that sat almost 60ft below the temple. Near one of the entrances, they found a trove of artefacts which includes jade statues, jaguar remains, and a box filled with carved shells and rubber balls. And of course, they also found liquid mercury. This is not the first time liquid mercury has been found at an ancient site. Dr Rosemary Joyce said at the time archaeologists have found mercury at three other sites around Central America (Picture: INAH/Handout via Reuters) Dr Gómez suggests that the liquid may have symbolised an underworld river or lake. This idea is echoed by Dr Annabeth Headreck, a professor at the University of Denver. She told the Guardian that the shimmering reflective qualities of liquid mercury could have resembled 'an underworld river, not that different from the river Styx' (Picture: REUTERS/Henry Romero) She said: 'Mirrors were considered a way to look into the supernatural world, they were a way to divine what might happen in the future. It could be a sort of river, albeit a pretty spectacular one' (Picture: Apolline Guillerot-Malick/SOPA Images/LightRocket via Getty) Over the next 16 years, Dr Gómez and his team excavated over 3,000 ceremonial and ritual artefacts and have now developed a comprehensive survey of the pyramid and tunnel using LiDAR scanners and photogrammetry. And a few archaeologists have contributed their knowledge of the pyramid site and its cultural significance to amplify their understanding of the site (Picture: DeAgostini/Getty) The temple of Quetzalcoatl is a monument which lies in the centre of the Mesoamerican Teotihuacan universe. It sits around 12 miles northeast of Mexico City in the ancient city of Teotihuacán. It was designated as a UNESCO World Heritage site in 1987, and receives around 4.5 million visitors annually. The Aztecs referred it as the place where the Gods were created, and the Quetzalcoatl is the third largest pyramid in the city (Picture: REUTERS/Henry Romero)

During an excavation project researchers discovered large amounts of liquid mercury in 2015. Its something experts believe means the structure was used to 'look into the supernatural world.'

Dr Annabeth Headrick agreed with this interpretation, telling the Guardian that the the qualities of liquid mercury might appear to resemble "an underworld river, not that different from the river Styx.

"It could be a sort of river, albeit a pretty spectacular one," Dr Headrick added. The Quetzalcoatl Temple is located around 12 miles northeast of Mexico City in Teotihuacán - the heart of the Mesoamerican Teotihuacan universe. Around 4.5 million people visit the temple - which is the third largest in the city - every year. It became a UNESCO World Heritage Site in 1987, and was listed on the World Monuments Watch in 2004 as tourist visitation led to the site's deterioration. More than a hundred human remains, which may have been sacrificial victims, were found under the structure in the 1980s. The Aztecs believed it was the place where Gods were created, with sacrifices being made as tributes. 6 The Temple is around 1,800 to 1,900 years old Credit: Getty 6 It is the third largest temple in the Teotihuacán region of Mexico Credit: Getty
