The solar system is famously vast, but new data from scientists has revealed that it extends even further than once thought. It is a discovery that was made thanks to distant objects that were spotted during a scan of telescope images. They appeared to show faint signs of rock located beyond Pluto, suggesting that the material of the solar system extends further into interstellar space than was previously believed. The new method of looking at telescope images has dispelled decades of hypotheses from astronomers who believed that the Kuiper Belt, a circumstellar disc in the outer solar system, becomes suddenly more sparse from 48 times the distance between Earth and the Sun. But, belts of rubble have now been seen extending out more than twice the distance experts previously thought. The discovery was made by a team of astronomers who were led by Canada's Herzberg Astronomy and Astrophysics Research Centre who were on a mission to find new targets for the probe “New Horizons” to explore on its way through the outer reaches of the solar system. With light at the end of the solar system in short supply, experts realised if they stacked multiple images taken at different times, they could combine the light to increase the visibility of an object, increasing its visibility. Using machine learning to help them on their way, experts trained the system before testing it with real data captured from the Subaru Telescope on Mauna Kea in Hawaii. In comparison to humans, the technology identified more than double the amount of Kuiper Belt Objects, revealing to experts just how vast the solar system is. They presented their findings at the 54th Lunar and Planetary Science Conference 2023. While the team’s results have not yet been peer-reviewed, they appear to suggest that our solar system has a minimum of two rings of material stretching as far as the distance Pluto is from planet Earth.

In 2020, philosopher Toby Ord published The Precipice, a book on the risk of human extinction. The chances of "existential catastrophe" for humanity in the next century according to Ord? One in six. It was a shocking number that alarmed many. After years of being flooded with warnings over climate change, rogue AI, nuclear weapons and pandemics, it's hard to disagree that humans face worrying chances. In his book, Ord discusses a number of potential extinction events, some of which can be examined through history. His research involved looking at the number of space rocks that have hit the moon over its history to figure out the likelihood than an extinction-sized asteroid hitting Earth. This was, in fact, looked at in 2022 by French scientists Jean-Marc Salotti, he calculated the odds of an extinction-level hit in the next century to be roughly one in 300 million. By contrast, Ord estimated the risk to be one in a million, although he does point out a considerable degree of uncertainty. Probabilities can be hard to understand in this context. Traditional probability, for example, relies on observations and a collection of repeated events, but human extinction would be a one-off. But there is another way to think if, called Bayesianism, after the English statistician Thomas Bayes. It sees probabilities as a ranking system of sorts. Specific number predictions shouldn't be taken so literally, but rather compared to other probabilities to understand the likelihood of each outcome. Ord's book contains a table of potential causes of extinctions, accompanied by his personal estimates of their probability. From a Bayesian perspective, we can view these as relative ranks. Ord thinks extinction from an asteroid strike (one in a million) is much less likely than extinction from climate change (one in a thousand). However, even using Bayesianism traditionally requires the incorporation of observational evidence. So, what do we make of Ord's "one in six"? Well it's better to take it less literally but to think of it as a warning, to jump start action on issues such as climate change to hopefully reduce the risk of human extinction in the next century.

We're all familiar with the different basic tastes - sweet, sour, salty, bitter, and umami - but now scientists have found a sixth one where the tongue detects ammonium chloride. Research from USC Dornsife has discovered that protein receptors on the tongue not only respond to sour taste but also to ammonium chloride as well. Scientists were very much aware that the tongue responds to ammonium chloride, but haven't been able to specify which exact protein receptors... until now. The protein OTOP1 is responsible for this which can be found in the cell membranes and forms a channel for hydrogen ions moving into the cell. Whenever we taste anything that's particularly sour such as vinegar or lemon juice, OTOP1 is able to detect the acidity found in both of those. Therefore, given that ammonium chloride similarly affects the concentration of hydrogen ions within a cell, research was carried out on whether OTOP1 protein would react to this too. After lab-grown human cells with OTOP1 protein were created and exposed to acid or to ammonium chloride, the team found that ammonium chloride was a "strong activator" of OTOP1. “We saw that ammonium chloride is a really strong activator of the OTOP1 channel. It activates as well or better than acids,” Dr Emily Liman, a professor of biological sciences at USC Dornsife and study author. Now, perhaps you're wondering what ammonium chloride tastes like, one example of where it can be found is in salt liquorice candy which is popular in Nordic countries. “If you live in a Scandinavian country, you will be familiar with and may like this taste,” Dr Liman added. Though the flavour can be of an acquired taste and one that many may not be a fan of - but there is an explanation for this. “Ammonium is found in waste products – think of fertilizer – and is somewhat toxic, so it makes sense we evolved taste mechanisms to detect it,” Dr Liman explained.
