Performing a proper backflip becomes pretty important when you need to complete the backflip challenges in Jinzhou. Or perhaps you just want to know how to do a backflip for fun in Wuthering Waves, which is what we’ll explain below. Wuthering Waves: How to perform a backflip Backflips not only look cool, but once you learn how to do one you can easily pass the backflip challenges in Jinzhou. Completing these grants you a few nice rewards, and the only reason I learned how to backflip was from these challenges. You can do a backflip in Wuthering Waves by walking forward, jumping, and before you press the dodge button you stop pushing forward. Screenshot: PC Invasion Upon making it to these backflip challenges, I was confused about how a backflip was supposed to be performed, despite the NPC explaining it to me. The easiest way to explain how doing a backflip works is as so: Walk forward Jump Let go of the button/analog stick for walking forward Dodge S...

Like any other online multiplayer game, XDefiant has launched with a handful of error codes that are frustrating players. One annoying error is Bravo-08 which is preventing players from matchmaking. This guide explains potential fixes. XDefiant: How to fix Bravo-08 error code Fix #1: Check XDefiant servers First things first, you want to make sure the XDefiant servers are running smoothly. Considering the online nature of the game, a lot of the error codes stem from the servers having issues. Below are links that you can use to check XDefiant’s server status. XDefiant X account Ubisoft’s XDefiant official help page At the time of writing, the Ubisoft help page does state there is a “degradation of online services.” This could be the reason why players are receiving the Bravo error code. Fix #2: Restart router and check your wifi If the servers are running smoothly, then the Bravo-08 error could be occurring because of something on you...

When getting your first characters in Wuthering Waves, it is tempting to go all out and level them up right away, spending all your resources. However, maybe you should be saving them for something else. When should you level up your characters Really, the best thing to do when it comes to spending your valuable Resonance Potions on Resonators is to wait for a good pull. Rather than blowing everything on the first ones you get, it is best to wait until you get a 5-star resonator and work on them instead. There won’t be many for most people, so there will be time to collect more resources between 5-star pulls. In the meantime, it is possible to level up your other resonators or characters by simply playing Wuthering Waves. Fighting enemies and completing tasks will award XP and levels to your equipped party. So, rather than spending Resonance Potions on 4-star and below characters, you should save it for your 5-star resonators. Screenshot: PC Invasion So, before you...

Increasing your Chef Level in Wuthering Waves will grant you a ludicrous amount of rewards, and will fill your tummy at the same time. I would suggest not to sleep on this, as your Chef Level could prove rather lucrative. How to level up your Chef Level in Wuthering Waves Leveling up your Chef Level will be a passive process for most in Wuthering Waves, but I would say it’s worth actively thinking about considering how good the rewards are. Every time you cook a meal (not an ingredient), you’ll gain Proficiency, which will directly contribute to your Chef Level. As you gain Proficiency, you’ll level up your Chef Level and get rewarded at certain milestones. Note that the more demanding a dish is, the more Proficiency you’ll get from it. Screenshot: PC Invasion Each dish will only be able to net you so much Proficiency, however, so you can’t farm the same meal ad nauseum to fast track your Chef Levels. The max amount of Proficiency one meal c...

Saying the Quiet Part Out Loud

Laili rock shelter on the island of Timor, north of Australia, appears to provide the smoking gun to rule out what was once considered the obvious route for one of the greatest and least understood migrations in human history. In the process, it may tell us something important about how people first arrived on Timor itself, and islands like it.The ancient presence of humans in Australia provides a major puzzle for anthropologists, particularly since it became clear how far back that began. Australia’s wildlife proves it was never connected by a land bridge to Southeast Asia, so the first inhabitants must have had the capacity to cross wide expanses of water. Yet interaction with what is now Indonesia apparently stopped, only resuming far more recently.Initially, it was widely believed that the first Australians reached their new home from Timor, now referred to as the “southern route.” Although today this requires crossing hundreds of kilometers of water, during the last Ice Age when sea levels were lower, Australia stretched much further northwest.However, for some time Professor Sue O’Connor of the Australian National University and other anthropologists have been raising questions about this path. There is no evidence of human habitation on Timor prior to around 50,000 years ago. Meanwhile, the oldest stone tools in Australia have been found in a layer of sediment deposited at Madjedbebe 65,000 years ago.Around a dozen sites of human habitation on Timor have been excavated, with no signs of an earlier human presence. However, O’ Connor told IFLScience that at most of these sites, the oldest evidence of humans sits directly on bedrock. “If the human presence is at the base of the cave a big erosion event may have removed all the sediment,” leaving uncertainty as to what was there before.However, at Laili on Timor’s north coast, O’Connor and co-authors of a new study found layers thick with tools, the remains of fire, and fishbones dating back to around 44,000 years ago, then a sudden shift. Below were meters of yellow sediment, with no signs of human presence other than the occasional younger tool or bone that had been pushed down. The contrast between this yellow sediment and the darker layers above formed through the mixture of ash makes this “a non-occupation layer” in O’Connor’s words, showing the site was definitely not occupied 55,000 years ago.Multifunctional stone tools found in layer 20 at Laili, the first human that shows evidence of human presence, in stark contrast to what is below.Image Credit: Shipton et al/Nature Communications. CC BY 4.0Theoretically, people might have been in Timor at the time, but chosen to live elsewhere, but O’Connor considers this unlikely. Laili holds the oldest evidence of humans on Timor yet, found after many searches. Moreover, it’s hard to imagine inhabitants ignoring such an attractive site for long. It sits near a large river that would have provided fresh water, and is within walking distance of the sea, where Timor’s residents would have got most of their food before agriculture. Where other sites sometimes have only a few signs of humans in their oldest inhabited layers, suggesting occasional use by small bands of people, Laili is rich with signs of humanity from the first dark layer.In some places, the evidence of ancient human presence is now submerged, after attractive coastal plains sunk when the Ice Age ended. However, O’Connor told IFLScience that Timor is different, plunging to the edge of the continental shelf almost immediately offshore. Geologic activity has also been raising the island, almost keeping place with sea level. “Laili Is 4 kilometers [2.5 miles] from the sea today; 45,000 years ago it would have been 5 kilometers [3.1 miles],” she said. There’s little scope for former sites to be lost.This leaves two explanations for Australia’s habitation. Either the dates at Madjedbebe are wrong, as a few anthropologists claim, and Australia was also uninhabited until about 45,000 years ago, or people got there another way.Supporters of the first idea note that it is the sediments, not the tools, that were dated at Madjedbebe. Perhaps humans arrived much later, but deliberately or accidentally buried tools in older deposits. Alternatively, they arrived via the “northern route”, crossing the Wallace Line to Sulawesi and then island hopping to New Guinea, connected to Australia at the time.Humans besides Homo sapiens lived on Sulawesi 200,000 years ago, but the oldest signs of our own species are a similar age to O’Connor’s finds on Timor. However, Sulawesi is a much larger and less explored island. It’s plausible humans were there long before they started painting the walls.O’Connor also told IFLScience that Sulawesi would have been a much more attractive location for humans looking to expand beyond mainland Southeast Asia. It has plenty of game such as deer, pigs, and possums that would have been familiar to arrivals from the mainland. “Timor has nothing but rats and bats,” O’Connor told IFLScience. Indeed, the absence of large mammals is part of the reason most caves there lack pre-human sediment, as cave users can track in mud or leave droppings.Timor’s sparse resources might not have mattered if people got there by chance, but the team doubts that was the case. “The traditional view held by researchers is that early humans who were making these significant water crossings were stumbling upon these islands by mistake, largely because it was so long ago,” co-author, ANU’s Dr Shimona Kealy, said in a statement. “Their arrival on Timor was no accident. This was a major colonization effort, evident through the sheer number of people who were making the journey. It’s a testament to these peoples’ level of maritime technology and the boats they created, but also their confidence and competence in braving maritime crossings.”The work is published open access in the journal Nature Communications. 

In the bitterly cold waters of the Arctic Ocean, scientists have discovered a strange and unique coral that’s “almost certainly a new species.”When you think about corals, you might imagine tropical temperatures, crystal-clear waters, and clownfish. However, corals are incredibly diverse and inhabit many different ecosystems across the planet, from the idyllic atolls of the Pacific to the darkest depths of the ocean. There's even an abundance of Arctic corals located along the edge of the continental shelf where water temperatures are just above zero degrees Celsius (32°F).The latest discovery was made by a team of researchers from the The Nippon Foundation-Nekton Ocean Census that’s currently on a mission to document the depths of the Arctic Ocean. They set off from Tromsø in northern Norway on May 3 aboard the ship RV Kronprins Haakon and will be wrapping up their expedition this week.The potentially new species of coral were found living on the stalk of a crinoid, also known as sea lilies. Ocean Census released a video of their experts discussing the discovery – and, as you can see, they’re pretty excited about it.                   “We've seen very, very few corals since we've been here in the Arctic. On the dive today, we saw lots of these crinoids growing, and what we found on this crinoid is a coral living on the crinoid stalk. It's almost certainly a new species,” Professor Alex Rogers, Principal Investigator at Ocean Census, explains in the video.“It really demonstrates coevolution in the deep sea but also how effective the remotely operated vehicle [ROV] is. We get the specimens in such good condition that those sorts of relationships are actually preserved,” Rogers added.The curious coral is just one of the expedition's finds over the past few weeks. They previously explored the Svyatogor Ridge, a site at a depth of around 3,700 meters (12,140 feet) within the Arctic mid-ocean ridge system that’s loaded with hydrothermal vents. In this strange environment, rich in methane and sulfur, their ROV snooped around the array of chemosynthetic communities that live here, including tube worms and shelled bivalve mollusks.The coral was found living on the stalk of a sea lily.Image courtesy of Ocean Census & Martin HartleyThe expedition is especially significant because this environment is facing several existential threats. Along with being impacted by climate change, some of these unique habitats are being eyed-up for deep-sea mining. This would essentially involve dredging the seafloor looking for nuggets of rare metals, like lithium and cobalt, potentially causing irrevocable damage to the fragile ecosystems that dwell here.“Understanding every aspect of our ecosystem holds immense significance. Today, we possess new tools, empowering us to uncover discoveries previously beyond our reach. Innovations such as eDNA analysis, advancements in taxonomy, and machine learning represent sophisticated means of gathering essential information,” Jan-Gunnar Winther, Pro-rector for Research and Development at UiT The Arctic University of Norway and Specialist Director at the Norwegian Polar Institute located in Tromsø, said in a statement.“With our current capabilities to amass vast amounts of data and consolidate it effectively, there lies tremendous potential. If this data is made accessible and shared widely, not just by those who collected it, it could have a profound impact on scientific understanding,” Winther added.
