How the discovery of an ancient stone tool could rewrite human history
Neanderthal-like stone tools, made using the Quina method, have been discovered in China, challenging the conventional understanding of human evolution in East Asia.
This discovery disputes the idea that the Middle Stone Age (between 300,000-30,000 years ago) was a period of stagnation in East Asia, while Europe and Africa saw significant advancements.
A Quina stone scraper, thick and asymmetrical with a broad and sharp working edge, was found with clear signs of use and resharpening.
Researchers are uncertain whether this technology was introduced to East Asia by westward migration or developed independently.
Further investigation, including the search for ancient human remains, may reveal whether this technology is linked to Neanderthals, Denisovans, or even an unknown human ancestor.

Scientists have a new way that we can find out if aliens exist
'Are we alone in the universe?' is a question humanity has long asked. But a team of scientists has created a new way to answer whether aliens exist. Daniel Apai, an astrophysicist and astrobiologist at the University of Arizona, studies exoplanets – worlds that orbit other stars. Figuring out if exoplanets are habitable is tricky, as they're too far out of reach to properly research. Instead, stargazers and space officials narrow the list of habitable planets down by whether they have water. Apai and his colleagues developed a model that shows how Earth organisms would fare on alien worlds by considering factors beyond water, like temperature or a creature's metabolism. Not every planet is a blue marble like Earth: 'Hot Jupiters' are gas giants that orbit blisteringly close to their stars, 'super-Earths' are our planet's big older brothers and loner rogue planets drift through space. So rather than asking what all life needs, Apai instead asked: 'Would the conditions in the habitat – as we know them – allow a specific (known or yet unknown) species or ecosystem to survive?' He wrote in The Conversation. 'Even on Earth, organisms require different conditions to survive – there are no camels in Antarctica. By talking about specific organisms, we made the question easier to answer.' Take the camel, Apai said. Under his team's 'quantitative habitability framework', they first look at what conditions the animal needs to live beyond water, such as a hot, dry climate. Next, they look at the habitat, with Antarctica being an icy wasteland, it 'would correctly predict a near-zero probability that Antarctica is a good habitat for camels'. To test the model, published on arXiv, the researchers looked at if methanogens, one of the oldest forms of life, could make it on the exoplanet TRAPPIST-1e-like. The model said the 'habitat suitability' for these one-celled organisms would be 69%, making it a good candidate for astronomers to examine. Closer to home, the model said the suitability for methanogens just below the surface of Mars or the oceans of Jupiter's moon, Europa, is at most 55% and 50%, respectively. TRAPPIST-1e-like also has a habitat suitability of between 13% and 80% for cyanobacteria, commonly known as blue-green algae. More Trending Evidence of alien life in the universe right now is next to none, and with all the space in the universe, scientists only have so much time and resources to work out if a planet or moon could host extraterrestrials. Apai hopes the model will help scientists think outside the box when it comes to what life can look like and know where best to look for it. The researchers will make a massive database of critters that live in extreme environments, such as insects that live in the Himalayas or microorganisms that live in hydrothermal vents on the ocean floor. Apai said: 'If scientists do detect a potential signature of life, this approach can help assess if the environment where it is detected can actually support the type of life that leads to the signature detected.'

Super Earth in ‘Goldilocks zone' discovered with new alien-hunting tool – now it will search for more habitable planets
Located in the Lyra constellation, the Super Earth planet completes an orbit of its nearby star every 207.5 days ET PHONE HOME Super Earth in 'Goldilocks zone' discovered with new alien-hunting tool – now it will search for more habitable planets Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) SCIENTISTS have stumbled across a new Super-Earth that orbits inside its star's habitable zone with a new alien-hunting tool. Searching for Earth-like planets - and Earth-like life - is the ultimate goal for planetary science.

An international team of scientists, led by the Yunnan Observatories of the Chinese Academy of Sciences (CAS), have used a new technique to find these potentially habitable worlds. It's called the Transit Timing Variation (TTV) technique - which looks for changes in the predicted transit times of an exoplanet. If the time changes, it could indicate the presence of other unseen planets in the system that are gravitationally influencing the transiting planet. The technique is a good way to detect smaller planets that would otherwise be difficult to find By analysing the TTV signals of Kepler-725b, a gas giant planet in the same system, the team were able to find its hidden sister planet Kepler-725c, according to a new study published in Nature Astronomy. Researchers said the technique offers a promising alternative in the hunt for "Earth 2.0." Kepler-725c has 10 times the mass of Earth and is located in the habitable zone of the sun-like star Kepler-725. It receives roughly 1.4 times the solar radiation than Earth does. Best-ever sign of ALIEN life found on distant planet as scientists '99.7% sure of astounding biological activity signal' Located in the Lyra constellation, the Super Earth planet completes an orbit of its nearby star every 207.5 days. During part of this orbit, the planet enters its star's habitable zone - meaning it could host alien life. Little else is known about the planet so far. It is the first time it has been used to discover a Super-Earth, a type of rocky exoplanet that is larger than Earth but too small to be considered a gas giant like Neptune. Astronomers have relied on alternative techniques to find exoplanets for decades. Like the transit method, where astronomers track how the light from a host star dims when a planet passes in front of it. Or through radial velocity (RV) observations, which is when scientists watch the slight wobble of a star as it interacts with the gravitational pull of an orbiting planet. However, both of these techniques have their flaws and make it difficult to detect planets with long orbital periods. The transit approach, for example, requires a planet's orbit to align exactly with our line of sight from Earth. Whereas the RV method requires extremely high-precision measurements, which makes it harder to find smaller planets. 3 An artist's impression of the Kepler-725 system - the small planet in the lower right is the newly discovered Super-Earth in the habitable zone Credit: Gu Shenghong All you need to know about planets in our solar system Our solar system is made up of nine planets with Earth the third closest to the Sun.

Archaeologists finally crack origin mystery of Tibet's ‘ghost ancestors'
Archaeologists have discovered that the ancestors of the Tibetan people, including a mysterious group known as the 'ghost' population, came from China 's Yunnan province more than 7,100 years ago. Researchers say the discovery helps solve an important mystery about how humans spread across East Asia. Scientists studying ancient DNA from East and Southeast Asia know that humans started spreading across the continent at least 19,000 years ago and that they split into northern and southern branches early on. But there are significant gaps in our understanding of the genetic origin of modern populations such as the Tibetans. Tibetan people carry genes from northern East Asians but also from an unknown group – the 'ghost' population – which some archaeologists think may be linked to ancient humans such as the Denisovans or an early group of modern humans from Asia. Denisovans are 'an extinct group of archaic humans previously known mainly from remains discovered in Siberia and Tibet ', according to the European Research Council. Previous research has pointed to China 's Yunnan region as the key to understanding the origins of Tibetan as well as Austroasiatic populations, referring to ethnic communities in Southeast Asia who speak Austroasiatic languages like Vietnamese, Khmer, and Mon. Studies indicate that about 80 per cent of the genetic makeup of Tibetan people comes from northern Chinese populations who lived between 9,500 and 4,000 years ago. The ancestry of the remaining 20 per cent remains unclear and is referred to as Tibet 's 'ghost' population. In a new study, scientists sequenced DNA from over 125 individuals who lived in Yunnan between 7,100 and 1,500 years ago. They compared the ancient genomes to the DNA of modern Tibetans and found that one person who might belong to the 'ghost' group carried genes of both ancient and modern Tibetans. This 7,100-year-old individual from Yunnan was discovered to be as genetically distinct from most modern East Asians as a 40,000-year-old person from the area now known as Beijing, indicating a previously unknown Asian ancestry. Scientists say this individual is the first known potential representative of Tibet 's previously uncharacterised 'ghost' lineage. Researchers suspect this lineage likely diverged from other early Asian people over 40,000 years ago and managed to survive in southern regions due to more stable climates during the Ice Age. They discovered that a unique 'central Yunnan' ancestry, different from the known northern and southern East Asian groups, appeared some 5,500 years ago and helped shape the genes of people speaking Austroasiatic languages today. This ancestry seems to have emerged before the widespread adoption of agriculture in the region, suggesting demographic expansions likely preceded the spread of farming. The findings show that Yunnan was for long an important crossroads where different groups of people met and mixed. 'This study not only fills a critical gap in the genetic data of prehistoric populations in East and Southeast Asia but also identifies one of the Tibetan Plateau's 'ghost ancestors' for the first time from a genetic perspective,' researchers said.
