Scientists make revelation about origins of life on Earth
Researchers have discovered complex organic molecules, considered precursors to life's building blocks, within a disc surrounding a protostar.
This finding addresses a crucial missing link, demonstrating that these complex molecules can survive the violent process of a protostar evolving into a young star.
The survival of these molecules means they can be inherited by planet-forming discs, suggesting that life could be more abundant than previously thought.
The significant findings have been reported in a new study published in The Astrophysical Journal Letters.

Scientists have found weird animals at the bottom of the ocean that challenge our understanding of life
Strange animals found at the bottom of the ocean challenge our current understanding of life, scientists have said. Researchers diving almost 10,000 meters deep into the Pacific Ocean found tube worms and molluscs that get their energy from chemical reactions, they say. That suggests that life is able to prosper in more extreme environments than we realised, researchers say – and there could be many more such strange animals waiting to be found. Some researchers have even suggested that studying life that thrives in such extreme environments could help us understand where and how alien life might be found elsewhere in the universe. When organisms live in extreme environments, they must find different ways to produce energy. Some of them use chemosynthesis, which gather their energy from chemical reactions rather than the light-based photosynthesis that supports the life we see around us. Many of those chemosynthesis-based communities can be found deep under the sea, thriving on the hydrogen sulfide and methane that seep up from the floor. Researchers have now found such life deep in the ocean, after an expedition that saw them climb into a submersible and examine 2,500 kilometres of trenches in the northwest Pacific.

Joe Rogan is stunned by 'alien probe' hurtling towards Earth at 130,000mph
Joe Rogan expressed shock during his podcast after reading a article detailing a mysterious interstellar object reportedly on a path toward Earth. NASA has identified the object, named 3I/ATLAS, as a likely comet, but Harvard astrophysicist Avi Loeb has proposed a more controversial theory, suggesting the object could be 'an alien probe.' Rogan said that the object is approaching from behind the sun, making it difficult to detect, adding that Loeb believes the object is on a direct trajectory toward Earth and could arrive in 2027. During Tuesday's episode of The Joe Rogan Experience, the podcaster read aloud from the article, reacting in real-time to its contents. ' The object measures roughly seven miles in diameter. Holy f***. How big is New York City?'* he said, astonished. 'Bigger than Mount Everest, making it the largest interstellar object ever spotted.' The article also included skepticism from astronomer Chris Lintott of the University of Oxford, who told Live Science that Loeb's theory was 'nonsense on stilts.' Rogan acknowledged the criticism but defended Loeb's credentials: 'Harvard is legit and Avi is a legit astronomer.' The podcaster then speculated that the object could be intentionally sent to Earth to wipe out humanity and reset civilization, similar to how the dinosaurs were wiped out. Rogan offered his scenario for what could happen if the object turns out to be an alien craft, suggesting 'that might be the end of the Earth.' He speculated that the timing of the object's arrival could coincide with a tipping point in the rise of artificial intelligence, imagining a future where AI gains control of the planet and deems humanity unsalvageable. 'It wipes everything out. Just like when the dinosaurs were here. Maybe that's how they reset the game,' said Rogan. In his view, such an extinction-level event could pave the way for a new beginning. 'We start fresh with new organisms, and then they come along and do genetic engineering, just like they did with us and monkeys, to create a new version of humans,' he continued. 'But this time, they make us a little less territorial, a little more inquisitive, more interested in innovation and less focused on controlling resources. Because that's what f**** us.' 3I/ATLAS was first identified on July 1 in data from the Vera C. Rubin Observatory in Chile. A team of more than 200 researchers determined that the object's nucleus, the solid core of a comet, is roughly 3.5 miles wide, and its appearance suggests it contains large amounts of ice and dust in a surrounding cloud known as a coma. However, Loeb recently challenged this classification in a preprint study published on arXiv. Loeb and his team found that 3I/ATLAS appears to lack a coma altogether, raising doubts about whether it is a natural object. According to the Harvard professor, the absence of a coma could mean the object isn't a comet at all but something artificial. 'The consequences, should the hypothesis turn out to be correct, could potentially be dire for humanity, and would possibly require defensive measures to be undertaken (though these might prove futile),' the study warned. Loeb's theory draws from a bleak scientific concept known as the Dark Forest Hypothesis, which suggests that intelligent civilizations may remain silent or act preemptively to eliminate threats, meaning they could view humanity as something to destroy before it becomes dangerous. 'As a scientist, I respond to evidence collected by instruments, the professor shared in a blog post on Wednesday. 'As of now, we have anomalies but we need more data on 3I/ATLAS or other interstellar objects in order to ascertain whether any one of them is technological in origin. 'Once we find an interstellar artifact beyond a reasonable doubt, the next step will be to figure out its technological capabilities and intent.'

EU climate goals at risk as ailing forests absorb less CO2, scientists say
COPENHAGEN/BRUSSELS/STOCKHOLM, July 30 (Reuters) - Damage to European forests from increased logging, wildfires, drought and pests is reducing their ability to absorb carbon dioxide, putting European Union emissions targets at risk, scientists warned on Wednesday. The European Union has committed to reaching net zero emissions by 2050. The target includes the expectation that forests will suck up hundreds of millions of tonnes of CO2 emissions and store it in trees and soil, to compensate for pollution from industry. But that assumption is now in doubt. The average annual amount of CO2 Europe's forests removed from the atmosphere in 2020-2022 was nearly a third lower than in the 2010-2014 period, according to a paper led by scientists from the EU's Joint Research Centre - its independent science research service. In the later period, forests absorbed around 332 million net tonnes of CO2 equivalent per year, said the paper, published in the journal Nature. Recent data from EU countries suggest an even steeper decline. "This trend, combined with the declining climate resilience of European forests, indicates that the EU's climate targets, which rely on an increasing carbon sink, might be at risk," the paper said. Today, Europe's land and forestry sector offsets around 6% of the EU's annual greenhouse gas emissions. That's 2% short of the amount the EU calculates is needed to meet climate goals - with the gap expected to widen by 2030. Agustín Rubio Sánchez, professor of ecology and soil science at the Polytechnic University of Madrid, said it was "wishful thinking" to rely on forests to meet climate targets. "Forests can help, but they shouldn't be assigned quantities to balance carbon budgets," he told Reuters. The findings are a political headache for EU governments, who are negotiating a new, legally-binding 2040 climate target - which is designed to use forests to offset pollution that industries cannot eliminate. Already, some are warning this won't be possible. "What should we do when there are factors that we, as countries, as governments, have not much ability to control - like forest fires or drought," Sweden's environment minister Romina Pourmokhtari said in a news conference last week. Over-harvesting, climate change-fuelled wildfires and droughts, and pest outbreaks are all depleting forests' carbon storage. However, some of these risks can be managed - for example, by reducing intense logging, or planting more diverse tree species, which may enhance CO2 storage and help forests withstand climate extremes and pests, the paper said.
