Apple has released a new version of its Pencil drawing tool, after days of speculation about updates for iPads. In recent days, some rumours have suggested that Apple was planning new versions of at least its base iPad and iPad mini, with a range of updates. But it appears those reports may be the result of confusion about the new launch, which actually just brought the new Pencil, which looks to be the only iPad-related updated so far. Apple refers to the new release as the “Apple Pencil (USB-C)”, and it now sits alongside the first and second generation of the drawing tool. Those will both remain on sale. The new version largely takes the features of the first generation and puts them into the more square design of the second-generation Pencil. But the new port is perhaps the most notable part, and may be the reason for the new release: until now, users of the base model iPad could only use the first-generation Pencil, but that uses a Lightning cable to charge, which is not supported by that iPad. The new Pencil also adds some features from the second-generation, however, including the option to place it wirelessly on the side of the iPad. The second-generation Pencil retains a host of extra features and a higher price. It can charge when attached magnetically to an iPad, includes the option to tap it to change tools, and to have it engraved. The updates mean that Apple now offers three versions of the Apple Pencil with different features and compatibilities, which can be compared on Apple’s website. The first generation remains available for $99, the new one will be $79 when it goes on sale next month and the second-generation is $129, or the same in pounds.

In space, discoveries continue to be made that challenge scientific beliefs, as distant objects reveal the solar system is much bigger than first thought and the observation was previously made that a part of the sun is broken. Now, there is evidence to suggest the existence of a ninth undiscovered planet that is at the very edge of the solar system and could point towards evidence that our understanding of gravity is wrong. The discovery was made by two scientists who studied the effects that the Milky Way galaxy had on objects in the solar system’s outer edge. Galaxies are able to rotate extremely fast without any of their contents escaping, and most experts believe that the existence of dark matter might explain why. Dark matter is invisible and does not emit, nor reflect light, and it is hypothesized that galaxies are surrounded by dark matter rings that bind the galaxies together in their own gravitation pull and stop them from emitting material. But now, the gravitational theory of Modified Newtonian Dynamics (MOND) may suggest that dark matter is not why galaxies stay intact despite staggering rotational speeds. Instead, some believe that under the rotational velocities experienced by galaxies, a new kind of gravitational behaviour occurs. Case Western Reverse scientist Harsh Mathur, explained: “MOND is really good at explaining galactic-scale observations, but I hadn’t expected that it would have noticeable effects on the outer solar system.” Planet 9 comes into play because objects in the Kuiper belt (the disk that surrounds the outer edges of the solar system) were observed clustering and exhibiting orbital anomalies that do not occur with other objects in the belt. Experts believe this may be due to the presence of an undiscovered ninth planet, as this is a phenomenon that occurred before with the discovery of new planets as their gravitation pull attracts other solar system objects. Katherine Brown, Hamilton College professor of physics, said: “We wanted to see if the data that support the Planet Nine hypothesis would effectively rule out MOND.” Their study revealed that the hypothesis could be correct and could point towards the existence of Planet 9, but they urged that their dataset was very small, so no definitive conclusions could be made. Brown explained: “Regardless of the outcome, this work highlights the potential for the outer solar system to serve as a laboratory for testing gravity and studying fundamental problems of physics.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

A group of scientists and philosophers claim to have identified a “missing law of nature”, in a discovery which has huge implications for our understanding of how, basically, everything works. Most of us are familiar with the names – if not the intricacies – of many of the physical laws which govern the world and beyond, such as gravity and thermodynamics. And yet, no established physical law has been able to describe the behaviours of countless complex systems that exist across the universe – until now. In a paper published in the PNAS journal on 16 October, a multidisciplinary team from some of the US’s top institutes and universities, unveiled a new law claiming to do just that. In a nutshell, their law states that evolution is not limited to life on Earth, it also occurs in other massively complex systems – from planets to atoms. This means that these systems naturally “evolve” to states of greater diversity, and complexity. In other words, the researchers found evolution to be a common feature of the natural world's complex systems which, according to the Carnegie Institution for Science, comprise the following characteristics: “They are formed from many different components, such as atoms, molecules, or cells, that can be arranged and rearranged repeatedly “Are subject to natural processes that cause countless different configurations to be formed.” Only a small fraction of these configurations survive via a process of natural selection called “selection for function”. According to the researchers, regardless of whether the system is living or nonliving, when a new configuration works and function improves, evolution occurs. The authors' new law – which they have christened "the Law of Increasing Functional Information" – states that the system will evolve "if many different configurations of the system undergo selection for one or more functions." "An important component of this proposed natural law is the idea of 'selection for function,'" the study’s lead author, astrobiologist Dr Michael L. Wong, explained. The team’s research builds on Charles Darwin’s theory of natural selection, which suggests the function exists to ensure the “survival of the fittest”. For their work, Dr Wong and his team expanded on this perspective, pointing to the existence of three types of this selection for function in nature. The first, most basic type, they claim, is stability – the stable arrangements of atoms or molecules which are selected to continue. Second, are dynamic systems which are selected for their ongoing supplies of energy. And the third, and most intriguing, function is "novelty" – the tendency of evolving systems to explore new configurations which can lead to surprising new behaviours or characteristics. Novelties are, ironically, nothing new. Indeed, life’s evolutionary history is rich with examples: photosynthesis evolved when single cells learned to harness light energy; multicellular life evolved when cells learned to cooperate; and species evolved thanks to advantageous new behaviours such as walking and thinking. The same type of evolution happens in the mineral kingdom, as the Carnegie Institution for Science notes in a release published by Phys.org. Indeed, Earth's minerals, which began with about 20 at the dawn of our solar system, now number almost 6,000 known today. This is thanks to the ever more complex physical, chemical, and biological processes which have occurred over the past 4.5 billion years. The paper also notes that just two major elements – hydrogen and helium – formed the first stars shortly after the big bang. Those earliest stars then used this hydrogen and helium to create around 20 heavier chemical elements, which was built upon by the next generation of stars. "Charles Darwin eloquently articulated the way plants and animals evolve by natural selection, with many variations and traits of individuals and many different configurations," co-author and research lead Robert M. Hazen explained. "We contend that Darwinian theory is just a very special, very important case within a far larger natural phenomenon. “The notion that selection for function drives evolution applies equally to stars, atoms, minerals, and many other conceptually equivalent situations where many configurations are subjected to selective pressure." The new law has a number of exciting implications, including a deeper understanding of how the Universe itself came to exist. It could also help explain how life differs from other complex evolving systems, and could help aid the search for life elsewhere. Furthermore, at a time when increasingly autonomous AI systems are of increasing concern, it’s very handy to have a law that characterises how both natural and symbolic systems evolve. It also offers insights into how we could artificially influence the rate of evolution of some systems which, again, could prove invaluable. The key point to remember, as Dr Wong put it, is that whilst life is the “most striking example of evolution”, it’s not the only one. Evolution, it transpires, is everywhere.

Minuscule traces of metal from space junk that's designed to be disposable are invisibly polluting the Earth's atmosphere, a new study has found. In recent times, spacecrafts launched into space have been designed so that they fall out of orbit and fall back down to Earth after their intended use. So instead of the materials crashing on land, they can burn up in the upper atmosphere. Although the debris of rockets and satellites burn up when re-entering the planet's atmosphere, the consequences of metal vapour being left behind currently remain unknown. But given the amount of space exploration taking place, the amount of metal vapour is expected to rise in the years to come. Physicist Daniel Murphy of the National Oceanic and Atmospheric Administration (NOAA) has led a team of researchers to investigate what effects this metal vapour could have as well as its impact over time and this study was published in Proceedings of the National Academy of Sciences, as per Science Alert. He listed "iron, silicon, and magnesium from the natural meteoric source" as the current refractory material in stratospheric particular. Murphy has warned how this composition could be affected by the metal vapour from space junk. "However, the amount of material from the reentry of upper-stage rockets and satellites is projected to increase dramatically in the next 10 to 30 years," he wrote. "As a result, the amount of aluminum in stratospheric sulfuric acid particles is expected to become comparable to or even exceed the amount of meteoric iron, with unknown consequences for inclusions and ice nucleation." To find out if metal vapour remained, Murphy and his team took and analyzed 500,000 stratospheric aerosol droplet samples to see if they had traces of spacecraft metals. Aerosols contain sulfuric acid droplets made from the oxidation of the carbonyl sulfide gas and in the atmosphere, this can appear naturally or as a pollutant. Metal and silicon traces can be found in these droplets too, acquired from meteors which vaporize upon atmospheric entry. Around 20 metals were discovered from this research, and while some metals had similar ratios to the vaporizing meteors, other metals such as lithium, aluminium, copper, and lead exceeded the anticipated amounts. Particles from vaporized spacecraft were found in 10 per cent of stratospheric aerosols over a certain size while other common spacecraft metals such as niobium and hafnium were also present. Consequently, these traces of spacecraft particles could affect how water freezes into ice in the stratosphere, and stratospheric aerosol particles could change in size. Due to more space exploration planned in an "era of rapid growth" for the industry, the researchers predict "the percentage of stratospheric sulfuric acid particles that contain aluminum and other metals from satellite reentry will be comparable to the roughly 50 per cent that now contain meteoric metals."

Scientists have unearthed a new species of wasp in the Amazon – and it's rather terrifying. The alien-looking parasitic creature came to light when a team at Utah State University were researching Allpahuayo-Mishana National Reserve in Peru. The wasp, known as Capitojoppa amazonica, has a giant almond-shaped head and is known to latch on to prey before sucking its blood and then eating it from the inside. It does so by laying eggs in its victims including caterpillars, beetles and spiders. The study’s lead author, biologist Brandon Claridge called the practice a "solitary endoparasitoid". "Once the host is located and mounted, the female will frantically stroke it with her antennae," Claridge told Live Science in an email. "If acceptable, the female will deposit a single egg inside the host by piercing it with her ovipositor (a tube-like, egg-laying organ)." He went on to explain that in some instances, "females will even stab the host with the ovipositor and feed without laying an egg as it helps with gaining nutrients for egg maturation." This isn't the first horrifying discovery, with researchers recently finding a new species of tarantula in Thailand that is characterised with illuminous blue legs. The spider is one of the rarest in the world, with Dr Narin Chomphuphuang explaining how it lurks in hollow trees. "The difficulty of catching an electric-blue tarantula lies in the need to climb a tree and lure it out of a complex of hollows," he explained. "During our expedition, we walked in the evening and at night during low tide, managing to collect only two of them."

Software company Adobe unveiled a new futuristic “digital dress” that lets wearers change patterns on its surface on the fly with the click of a button. The dress, created under Adobe’s “Project Primrose”, is made of sequins which are “reflective light-diffuser modules” built using liquid crystals such as those in smart lighting. Researchers say the sequins are basically tiny screens built using smart materials. The dress was unveiled for the first time for the audience at Adobe’s MAX conference last week with the software company describing it as bringing “fabric to life”. Video from the conference showed Adobe researcher Christine Dierk wearing the strapless outfit, which appeared like an average cocktail dress on first impression, but the patterns on it begin to shift immediately with the touch of a remote button. “Unlike traditional clothing, which is static, Primrose allows me to refresh my look in a moment,” the Adobe scientist said while demonstrating that its colors can go from light to dark in a moment. The researcher-turned-model also showed that the dress not only had static changes, but also animated designs with patterns fading in and out. Ms Dierk, who not only designed the dress but also stitched it herself, demonstrated that the outfit will even respond to movement. Researchers say the dress is built using “reflective-backed polymer-dispersed liquid crystal (PDLC)” a material commonly used in smart windows. “This low-power non-emissive material can be cut to any shape, and dynamically diffuses light,” scientists wrote in a study presented at a tech conference last year, but it remains unclear how heavy the dress can actually get. “Designers can layer this technology into clothing, furniture, and other surfaces to unlock infinite style possibilities – such as the ability to download and wear the latest design from a favorite designer,” Adobe noted. They said the high-tech sequins are also used for smaller products part of Project Primrose including a handbag and a canvas. “We hope this work inspires future designers of flexible displays,” scientists said.
