One of the key building blocks required for human life has been found in the depths of space. Astronomers have been looking out into a region 1,000 light-years from Earth, known as the Perseus Molecular Complex, and they’ve found an amino acid which is essential in human growth. Tryptophan is one of the 20 amino acids required for humans to develop. Babies require it to grow and it’s also important for protein development and muscle function in adults Readings from the Spitzer telescope, which is no longer in use, were crucial to the discovery.

Dr Susana Iglesias-Groth is from the Instituto de Astrofísica de Canarias and was lead author on the new research. "The evidence for tryptophan in the Perseus molecular complex should encourage additional effort to identify other amino acids in this region, and in other star-forming regions,” Dr Iglesias-Groth said. “It is a very exciting possibility that the building blocks of proteins are widely present in the gas from which stars and planets form – it may be key for the development of life in exoplanetary systems.” The findings were published in the Monthly Notices of the Royal Astronomical Society. It comes after research showed that life forms could potentially be able to survive in the conditions in the clouds above Venus. The key point revolves around the presence of the biosignature gas phosphine, which is often identified as a sign of life. It also posits the idea that potential life forms on the planet could use sulphuric acid the way life forms on Earth use water. Have your say in our news democracy.

Scientists have just uncovered billions of years’ worth of secrets buried beneath the surface of the moon. Our celestial companion has been a source of awe and mystery since time immemorial, but now, thanks to China’s space programme, we’re starting to piece together its past. In 2018, the Chang’e-4 lander, of the Chinese National Space Administration (CNSA), became the first spacecraft ever to land on the far side (or the dark side, if you'd prefer) of the moon. Since then, it has been capturing incredible images of impact craters and extracting mineral samples, offering a long-sought insight into the structures that make up the top 1,000 feet of the moon’s surface. Earlier this month, the Chang’e-4’s findings were finally published, and the world was invited to delve deep into the history of our cherished natural satellite. The results, published in the Journal of Geophysical Research: Planets, reveal that the top 130 feet (40m) of the lunar surface are made up of multiple layers of dust, soil, and broken rocks. Hidden within these layers is a crater, which formed when a large object slammed into the moon, according to Jianqing Feng, an astrogeological researcher at the Planetary Science Institute in Tucson, Arizona, who co-led the pioneering analysis. Beneath this, Feng and his colleagues discovered five distinct layers of lunar lava that spread across the landscape billions of years ago. Experts believe that our moon formed 4.51 billion years ago, when a Mars-size object crashed into Earth and broke off a chunk of our planet, as Live Science notes. Over the following 200 million years or so, the moon continued to be pummelled by space debris, with numerous impacts leaving cracks in its surface. Just like on Earth, the moon’s mantle contained pockets of molten magma, which infiltrated the newly formed cracks thanks to a series of volcanic eruptions, Feng explained. However, the new data provided by Chang’e-4 showed that the closer the volcanic rock was to the moon’s surface, the thinner it got. "[The moon] was slowly cooling down and running out of steam in its later volcanic stage," Feng said. "Its energy became weak over time." It is understood that volcanic activity on the moon died out between a billion and 100 million years ago, which means it is largely considered “geologically dead”. However, Feng and his co-authors have suggested there could still be magma buried deep beneath the lunar surface. Chang’e-4 still has much work to do, and Feng and his team hope this is just the beginning of their literally ground-breaking mapping of the moon.

A food delivery driver has taken to TikTok with claims his company marked the trip as "too short" to complete. In the viral clip, that's racked up almost 4 million views, Josh (@BikingDC) recorded himself collecting a coffee order from the vendor, before delivering it to a customer two blocks away. “Quick trip,” Josh jokes to the customer, who responded: "Yeah man, it’s hard to get out of the office." As Josh rides away, his phone shows a notification that read: "Can not complete delivery … The trip was too short to complete." Sign up for our free Indy100 weekly newsletter "Imagine doing your job so fast they app tells you to slow down," the TikToker wrote as the caption. "Homie ordered down the street because he cant leave post and i can respect that … but like i still need paid. [sic]." The footage was flooded with comments from baffled users, with one saying "They really need to fix that." Another joked: "Bro does his job so good that app can't process." "It’s probably because he bought normal delivery instead of priority so he has to take his time delivering it," a third theorised. @bikingdc Imagine doing your job so fast they app tells you to slow down ? Homie ordered down the street because he cant leave post and i can respect that … but like i still need paid ? #uber #ubereats #doordash #delivery #fooddelivery #bike #bicycle #washingtondc It comes after a separate food delivery driver hit out at their customer for giving a $5 (£3.90) tip. "I just wanna say, this is a nice house for a $5 tip," the driver says in footage captured on the video doorbell. In response, the customer responds: "You're welcome." The worker didn't take to the response too well, and yelled "f*** you," before heading back to his car. "I say 5$ is good since it was a 20$ order...seriously, what do they expect more than what the order is," one person wrote under the viral clip, as another chimed in: "Did he expect a 100 dollar tip on a 20 dollar order?"
