Ancient tombs (pictured) span large distances in the northwestern Saudi Arabian counties of Al-'Ula and Khaybar, aerial surveys carried out by the University of Western Australia reveal. They form 'funerary avenues' - long-distance 'corridors' linking oases and pastures - dating back to the Bronze Age. Most of the tombs are described as 'pendant' tombs because they resemble circular pieces of jewellery attached to a chain, or 'tail' (top right).
Rare 'rainbow-hued' blanket octopus that stretches its arms out to form a cape when threatened is spotted twirling through the Great Barrier Reef
A marine biologist had a 'once in a lifetime encounter' when she captured pictures and footage of a rare blanket octopus swimming through the Great Barrier Reef in Australia. First discovered in 1963, the marine animal gets its name from sheets of webbing that stretch between some of their arms. And it will stretch its arms out to create a blanket-like silhouette n the hopes of scaring away predators.
Metal plate implanted into head of Peruvian warrior 2,000 years ago is thought to be the world's first skull surgery and the patient - who had elongated his skull - SURVIVED
The Museum of Osteology in Oklahoma says the skull, which is in its collection, is reported to have been that of a man who was injured during battle before having some of the earliest forms of surgery to implant a piece of metal in his head to repair the fracture. Experts told the Daily Star that the man was believed to have survived the wound and the surgery, with the skill now a key piece of evidence in proving that ancient peoples were capable of performing complex surgeries. The skull in question is an example of a Peruvian elongated skull, which is an ancient form of body modification where tribe members intentionally deformed the skulls of young children by binding them with cloth or even binding the head between two pieces of wood for prolonged periods of time.
Travel like a superhero! Bizarre zero emission electric craft that will allow its 'Superman-like' pilot to whizz through the air at 160mph completes its first untethered flight test
The full-scale electric ZEVA Aero, created by Tacoma, Washington-based firm ZEVA, performed a series of unmanned flight tests in rural Pierce County on January 9. ZEVA Aero completed four flights, totalling more than four minutes of controlled hovering, simulated taxiing manoeuvres at slow speeds and limited vertical climb manoeuvres. The 'personal flying machine' can transition from an upright 'hover mode' to 'forward flight mode' where the passenger faces downwards as they zoom through the air in a 'Superman-like trajectory' (illustration bottom right).
All aboard the HS2 metaverse! 'Digital twin' of the high-speed track will allow engineers to put on a virtual reality headset and fix faults using data from Formula One-style sensors
Sensors will detect any faults or issues on train tracks and beam data back to a 3D digital replica, or metaverse, at a nearby control centre in Washwood Heath, Birmingham. HS2, which is estimated to cost more than £100 billion overall, aims to provide a high-speed rail service linking London and northern England. The first 'phase' of the line, between London and Birmingham, is expected to open between 2029 and 2033.
The most detailed 3D map of the universe EVER is under construction: Astrophysicists unveil stunning 'CT scan' of 7.5 million galaxies that are among 35 million set to be captured during five-year project
The Dark Energy Spectroscopic Instrument (DESI) has completed its first seven months of a survey that is expected to take a total of five years. An international collaboration of scientists, led by the US Department of Energy's Lawrence Berkeley National Laboratory in California, are using the survey to create a 'phenomenally detailed 3D map' that will help explain dark energy. It has so far catalogued over 7.5 million galaxies, and is adding more at about a million a month, on its mission to have a map showing 35 million unique galaxies. The aim of the project is to shed light on the mysterious dark energy, a force that makes up 68 per cent of the universe and is accelerating its expansion.
Fancy a byte to eat? Chinese restaurant chain is forced to use ROBOT waiters priced at £14,500 each after struggling with staff shortages during the Covid pandemic
Directors at The Chinese Buffet unveiled one BellaBot in each of four restaurants in Liverpool, St Helens, Bolton and Wigan, to serve food to diners in place of humans. Quirky footage shows Bella, who features a wide-eyed feline face, sweeping across the restaurant floor dishing out delicacies to delighted customers. The guide price for the friendly-faced robots is $20,000 (£14,500), which is less than the cost of employing a waiter at minimum wage for 40 hours per week.
Watch the Earth BREATHE: Mesmerising animation captures plants taking up and releasing carbon as the seasons change
The animation was created by an ecologist at the Max-Planck-Institute for Biogeochemistry in Jena, Germany. It shows the carbon cycle - the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Parts of the globe can be seen sinking as the Earth's plants suck carbon out of the atmosphere, but inflate when these plants release carbon.
Have astronomers discovered the first EXOMOON? Mysterious body that is almost three times the size of Earth could be orbiting a Jupiter-sized planet outside our Solar System
What's believed to be an 'exomoon' - a moon outside our solar system - is orbiting a Jupiter-sized planet called Kepler 1708b, 5,500 light-years away from Earth, report scientists at Columbia University in New York. The experts made the discovery using data from NASA's Kepler space telescope (inset), which was decommissioned in 2018.
A luxury boat that's perfect for high-flyers! 'Mega' 490ft-long superyacht-cum-blimp that is designed to FLY as well as sail is unveiled in futuristic concept
Called Air Yacht, the extravagant vehicle has been revealed in detailed concept images by the Rome-based company Lazzarini Design Studio, which has not revealed how much it might cost. The dry carbon fibre structure can reach 60 knots with its electric engines and two blimps, allowing it to fly, hover and float on the water too. Air Yacht is not an airship for public transportation or touristic purposes; rather, it is conceived for a private owner, according to the design firm. Luxury features include an on-board swimming pool (pictured) and a spacious living and dining area.
Robot with a pair of 'claws' at the end of humanoid-shaped arms is used to perform transvaginal hysterectomies at three US medical facilities
Hominis features a pair of 'pinching claws' attached to two humanoid-shaped arms. This robotic assistant is helping US surgeons perform transvaginal hysterectomies. Hominis enters through the vagina to perform the hysterectomy and then wraps its arms around the uterus to perform the operation.
HS2 dig unearths Roman market town in Northamptonshire: Ancient artefacts reveal how 30 Iron Age roundhouses were 'Romanised' into a wealthy trading settlement almost 2,000 years ago
Stunning artefacts have been found near the village of Chipping Warden in Northamptonshire. The site is known as Blackgrounds after the black soil found there. The presence of such a significant archaeological site in the area has been known since the 18th century, but recent geophysical surveys have revealed the original Iron Age part of the site. Findings include a Roman lead die surrounded by bone gaming pieces (top right) and more than 300 Roman coins (bottom right) - an indicator of the location's prosperity.
The future of farming? John Deere unveils its first driverless tractor that can be controlled by farmers using a smartphone and even stops ploughing if animals run in front of it
The US farming equipment giant revealed details of the adapted 8R tractor on the first day of the Consumer Electronics Show (CES) in Las Vegas on Wednesday. It comes with six pairs of cameras and artificial intelligence, allowing it to check its position to the inch, and stop if it detects an animal or object in its path. As well as selling an adapted 8R, John Deere said the cameras and computers for automated tilling can be installed on an existing tractor in just one day. The company will deliver up to 20 machines this year, with a scaled up rollout in the coming years - but is yet to decide if the new kit will be sold directly, leased or offered as a subscription.
Two weeks with the new Nokia 6310: Rebooted version of the iconic 'brick phone' is a welcome relief from social media and annoying apps - and Snake is just as fun as we remember!
Nokia's latest reboot, modelled on the original 6310 from 2001 (inset), may be the answer to a smartphone detox in 2022. The Espoo, Finland-based firm says the handset is a 'perfect tonic' for a yearning for nostalgia. It comes with a 2.8-inch screen, a 20-day battery life and the classic mobile game Snake - although the phone's camera is just 0.3 megapixels, resulting in some very grainy images.
Death of 'Throes:' Astronomers watch rapid self-destruction of a massive star in real time - for first time ever - as cosmic object collapses into a supernova
Throes, a red supergiant, was seen exploding and collapsing into a supernova by astronomers in real time. This is the first time this type of event has been witnessed by human eyes. Prior to this historic event, it was thought red supergiants showed no evidence of their soon-to-be explosions, but throes was found to emit a bright radiation leading up to its final days. The team put together an animation (pictured) (showing what they saw unravel during the star's transformation to a supernova.
Formula One of the future? Hydrogen-powered 'carcopter' that can reach speeds of 155 mph and costs £665,000 is to be tested on race circuits after being unveiled at CES 2022
French company Maca says it plans to test its eco-friendly £665,000 hydrogen-powered 'carcopter' on racetracks this year. It will have a top speed of 155mph, meaning a pilot onboard the 23ft craft can give Formula One stars a run for their money.But unlike the gas-guzzling machines driven by Sir Lewis Hamilton and co, this vehicle does not create any CO2 emissions and is fully recyclable. The firm hopes carcopter racing may even replace F1 as a sport.
Leonard lights up the night sky! Astrophotographer captures newly-discovered comet in extraordinary detail as it streaks through space in a blaze of blue, green and orange colours
Astrophotographer Andrew McCarthy (pictured inset) waited for several hours to capture Comet Leonard (main) from his home in Arizona after it made its closest approach to Earth on December 12. Images show the 'incredible structure and colour' around the comet's nucleus and its wispy, green-tinted tail. Comet Leonard was discovered by astronomer Gregory J Leonard on January 3, 2021, making it a relatively recent cosmic finding.
This is NOT a fish tale! Goldfish are trained to 'DRIVE' a robotic tank by swimming in a certain direction to show they can navigate on land as well as in the water
Six goldfish were trained to use a specially-made vehicle and find their way around a room towards a food reward, report scientists at Ben-Gurion University, Beersheba, Israel. The results suggest that fish can adjust their navigation skills 'to a wholly different terrestrial environment', according to the researchers, who have published their results in a new paper.
Many women have reported changes in their menstrual cycle after getting the COVID vaccine and new study validates these claims - it found after one shot cycles can be prolonged for 19 hours. However, a subgroup of app users who received two vaccine doses in the same menstrual cycle (358 users) had a larger average increase in cycle length of two days.
