Astronomers have discovered a new way that stars can die. In a study published in the journal Nature Astronomy, experts have worked out that a minute-long gamma-ray burst of light, which occured in 2019 and evidence a star dying, happened because stars collided within the densely crowded environment near the supermassive black hole at the centre of an ancient galaxy. Normally gamma-ray bursts (GRB) last around two seconds and happen when stars collapse. “For every hundred events that fit into the traditional classification scheme of gamma-ray bursts, there is at least one oddball that throws us for a loop,” said study coauthor Wen-fai Fong, assistant professor of physics and astronomy at Northwestern University’s Weinberg College of Arts and Sciences, in a statement. “However, it is these oddballs that tell us the most about the spectacular diversity of explosions that the universe is capable of.” Over time, astronomers have observed three main ways that stars can die, depending on their size. Lower mass stars like our sun shed their outer layers as they age, eventually becoming dead white dwarf stars.

Doing so can leave behind dense remnants like neutron stars or result in the creation of black holes. A third form of star death results when neutron stars or black holes begin to orbit one another in a binary system and spiral closer to one another until they collide and explode. But the new observation suggests a fourth type of death. “Our results show that stars can meet their demise in some of the densest regions of the universe, where they can be driven to collide,” said lead study author Andrew Levan, an astrophysics professor at Radboud University in Nijmegen, Netherlands, in a statement. “This is exciting for understanding how stars die and for answering other questions, such as what unexpected sources might create gravitational waves that we could detect on Earth.” “The lack of a supernova accompanying the long GRB 191019A tells us that this burst is not a typical massive star collapse,” said study coauthor Jillian Rastinejad, a doctoral student of astronomy at Northwestern, in a statement. “The location of GRB 191019A, embedded in the nucleus of the host galaxy, teases a predicted but not yet evidenced theory for how gravitational-wave emitting sources might form.” “While this event is the first of its kind to be discovered, it’s possible there are more out there that are hidden by the large amounts of dust close to their galaxies,” said Fong, who is also a member of the Center for Interdisciplinary Exploration and Research in Astrophysics at Northwestern. “Indeed, if this long-duration event came from merging compact objects, it contributes to the growing population of GRBs that defies our traditional classifications.” You learn something new every day.

Vegetarianism may be written in your DNA, a study has found. According to new research which analysed 5000 vegetarians and 300,000 meat eaters, there are genes associated with how well someone is able to adhere to a vegetarian lifestyle. Researchers identified three genes that are strongly identified and another 31 that are potentially identified with vegetarianism. In a genetic analysis, the researchers saw that vegetarians are more likely than non-vegetarians to have different variations of these genes. This might be because of how different people process lipids, or fats. Several of the genes that the study found to be associated with vegetarianism had to do with metabolising lipids and given plants and meat differ in the complexity of their lipids, it may be that some people genetically need some lipids offered by meat. “At this time we can say is that genetics plays a significant role in vegetarianism and that some people may be genetically better suited for a vegetarian diet than others,” said lead study author Dr. Nabeel Yaseen, professor emeritus of pathology at Northwestern University’s Feinberg School of Medicine. “A large proportion of self-described vegetarians actually report consuming meat products when responding to detailed questionnaires,” he said. “This suggests that many people who would like to be vegetarian are not able to do so, and our data suggest that genetics is at least part of the reason.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Experts have explained the reason why every glass of water we consume has dinosaur urine in it and it's not as gross as it sounds. When you get a cold glass of water from the tap, chances are you don’t think much about it before getting it down the hatch, so long as it looks clean. But, water experts have explained that the water you’re drinking may have gone through a dinosaur or even through your neighbour, before getting to you. This is because every drop of water on Earth has gone through a continuous water cycle over billions of years, and the amount of water on the planet at any given time is always the same. Severn Trent Water explained more, telling the Birmingham Mail how our planet's water cycle works. Sign up to our free Indy100 weekly newsletter They explained: “ Heat energy from the sun causes water to evaporate into the atmosphere from sea, lakes and the soil. “Air currents containing water vapour rise over higher ground into cooler temperatures which causes condensation and creates clouds. “More air currents cause the clouds to move around the Earth, across sea and land. As the clouds cool, precipitation as snow, sleet, hail or rain.” They explained that the vast majority of precipitation on Earth ends up back in waterways, such as seas, lakes and rivers. Continuing, they revealed: “97 per cent of the world’s water is salty sea water, two per cent is frozen in the polar ice caps and one per cent is fresh water for us to use.” Water companies collect and store water in reservoirs, which is then treated and tested by the Environment Agency and Drinking Water Inspectorate. It can then be distributed to homes through pipes. Then, the wastewater that has been used is transported through drains and sewers to sewage treatment works and returned to streams and rivers.
