Scientists have discovered an ancient skull in China, like no other they've seen before. The 300,000-year-old child skull was first discovered in Hualongdong back in 2019 alongside other fossil remains. The Chinese Academy of Sciences (CAS) have struggled to match them to a known lineage. The discovery left researchers baffled as it did not resemble Neanderthals or Denisovans, according to Science Alert. It led them to believe we are either missing a branch from the human family tree or need to add to it. While the skull had similarities to early modern humans, there is a lack of chin and was likened to an extinct species of human in Asia known as a Denisovan. This shape has "never been recorded in late Middle Pleistocene hominin fossil assemblages in East Asia," scientists said in a recent analysis. They believe the remains, known in the science world as HDL 6, could possibly be a combination of modern human and unknown hominin that existed in China, according to the outlet.

The tomb is guarded by a terracotta army of soldiers and horses and was found by farmers back in 1974 in the Shaanxi province of China. Not only do archaeologists believe it will cause damage, but there are rumours of deathly booby traps that could kill curious intruders, according to IFL Science. Writings by Chinese historian Sima Qian 100 years after Qin Shu Huang's death claim "Palaces and scenic towers for a hundred officials were constructed and the tomb was filled with rare artifacts and wonderful treasure." He continued: "Craftsmen were ordered to make crossbows and arrows primed to shoot at anyone who enters the tomb. Mercury was used to simulate the hundred rivers, the Yangtze and Yellow River, and the great sea, and set to flow mechanically." Have your say in our news democracy.

Scientists are trying to work out the source of dark matter. A group want to house a giant international particle detector that would be built 3,000ft underground in a working mine in Boulby, North Yorkshire to find the cause of the mysterious space matter. “We are entering the last-chance saloon to show that these particles are the cause of dark matter, and we want to make sure Britain is at the heart of that work by building the final generation of these detectors,” physicist Professor Chamkaur Ghag of University College London told the Observer. Scientists know the universe contains more matter than can be seen directly because they can see galaxies held together in clusters when they should be flying apart. Extra mass must be generating more gravity and holding these galaxies together, Most researchers think particles called weakly interacting massive particles – Wimps - are the source of dark matter. But these Wimps are hard to detect so scientists are trying to have a proper stab at it by combining resources and working in one Yorkshire site. “And what we are striving to do in Britain is to get it built at Boulby. Essentially, we want the last-chance saloon for Wimps to be built in the UK,” said Ghag. Dark matter accounts for around 85 per cent of the universe’s mass.There are also mines in South Dakota, and near Rome in Italy that are also hunting for Wimps which could provide answers.

Sex toys may seem harmless, but many have not been assessed for health risks and could have terrible effects. According to experts, our body may absorb the chemicals in the toys and recent experiments at Duke University found that four different sex toys, including anal toys, beads, dual vibrators, and external vibrators, shed nanoplastic fragments when mechanically rubbed and scraped. What's more, all these sex toys were found to contain phthalates; a group of chemicals that that can damage the liver, kidneys, lungs, and the reproductive system, at high enough concentrations. More research needs to be done to see if adults can absorb these chemicals when using sex toys on permeable tissues but it doesn't sound great. Sign up to our free Indy100 weekly newsletter Especially as the United Kingdom lacks specific chemical regulations for sex toys. "Some of the phthalates identified in our experiments have been observed concurrently with serious fertility complications or loss of fertility in rodents at high concentrations," the authors of the study wrote, "though causation may not have been demonstrated, the correlation is concerning enough to warrant further investigation."

Self-conscious people may suck in their stomachs - but doing so can be unhealthy. Adam Taylor, Professor and Director of the Clinical Anatomy Learning Centre, Lancaster University, has explained that the habit can create abdominal imbalance and all sorts of problems. In an article, he explained: "This can lead to a condition called 'hourglass syndrome; – a detrimental change in the structure of the abdominal wall, which may cause a visible crease to form in the mid-abdomen. Not only that, but this change can also have a knock-on effect on the internal organs and other parts of the body if left untreated." He added: "When we suck our stomach in it causes our rectus abdominis (commonly referred to as our "six-pack" muscles) to contract. But since we tend to store more fat tissue in our lower abdomen, the muscles at the top of the stomach tend to be more active. This creates a fold or crease in the abdomen over a long period, with the belly button being pulled upwards. "Sucking the stomach in places greater pressure on the lower back and neck. This is because they now have to compensate for changes in core stability." Sign up to our free Indy100 weekly newsletter He also said it may lead to changes in breathing capacity, though said more research needs to be done, and said sucking in the abdomen also puts strain on the pelvic floor which could cause incontinence. Fortunately, hourglass syndrome is reversible through exercises that strengthen core muscles like planks or bridges, he explained. And he also said the condition develops over weeks of consistently sucking in the stomach. "So occasionally sucking the stomach muscles in is not likely to cause problems," he said.

Record-setting wildfires and deadly heat waves across the globe are providing the most tangible evidence of climate change

How many cups of coffee are too many cups of coffee to drink in a day when it's on your employer's dime? Researchers dug down to find the answer.

A chemical reaction that gives food flavour could have helped evolution, one study suggests. According to New Scientist, the Maillard reaction is when the temperature between sugars and amino acids rises above approximately 140°C. It often occurs in food such as toasted bread, meats and roasted vegetables. Caroline Peacock at the University of Leeds wanted to explore whether it could happen at lower temperatures. To do this, scientists added iron or manganese minerals to a solution made up of sugar glucose and the amino acid glycine. When the substance was incubated at 10°C, the process was sped up by around 100 times. The temperature is said to be similar to the seabed at the edges of continents. Peacock and the team discovered that the Maillard reaction also occurs on the ocean floor, where iron and manganese minerals are often found. If this is the case, it could cause the carbon in sugars and amino acids to be stored in "large, complex polymers that microbes find harder to ingest," Peacock said, as per the publication. Sign up for our free Indy100 weekly newsletter "If you can get your carbon through the 1-metre danger zone [at the top of the sea floor], where carbon generally is attacked and degraded and turned back into carbon dioxide by microbes, that will lock it away from the atmosphere," she explained. The team estimated that the minerals could lock away roughly 4 million tonnes of carbon every year. If this process didn't exist, the atmosphere could have warmed by a further 5°C over the past 400 million years, the study suggested. "This process has such a profound impact on atmospheric oxygen," she says. "Because complex life forms require higher levels of oxygen, as they’re more energetically demanding, we think it’s reasonable to surmise this process had a hand in creating conditions required for complex life."

So far this year, we’ve mostly been seeing artificial intelligence pop up on our timelines as a tool for creating trivial things like odd news songs from classic bands or bizarrely sexualised images of classic artworks However, it looks like AI had a vital practical implementation recently after spotting a dangerous asteroid heading close to Earth that was originally missed by scientists. A 600-foot asteroid named 2022 GN1 was found thanks to a new algorithm, and it was revealed that our planet had a close shave with the object last year. As it’s now been revealed, 2022 GN1 flew a relatively close 4.5 million miles from Earth in September 2022. Sign up to our free Indy100 weekly newsletter It sounds like a huge distance, but it falls within the definition of a potentially hazardous asteroid (PHA). At the time, it was completely missed due to it being obscured by starlight from objects in the Milky Way. The algorithm, named HelioLinc3D, spotted the object after observing data from the Zwicky Transient Facility (ZTF) telescope. The team leader behind the algorithm, Mario Jurić, released a statement saying: “This is just a small taste of what to expect with the Rubin Observatory in less than two years, when [the algorithm] HelioLinc3D will be discovering an object like this every night. “But more broadly, it’s a preview of the coming era of data-intensive astronomy. From HelioLinc3D to AI-assisted codes, the next decade of discovery will be a story of advancement in algorithms as much as in new, large, telescopes.” Meanwhile, scientists think they have come up with a new approach to mitigating global warming: put up a giant “umbrella” in space to protect the Earth from excess sunlight.
