Singularity Player Commands - EVE Community

If the world as we know it comes to an end (maybe even starting with an earthquake, birds and snakes and airplanes), future generations will have access to a vault containing duplicates of seed samples from the worlds crop collections, a frozen Noahs Ark of animal DNA to bring species back from extinction, and if a new initiative pans out as intended, a black box to record how it all went down.

This week saw the launch of Earths Black Box, a well-intentioned but somewhat morbid project of questionable value in Tasmania, Australia. An Australian marketing communications company called Clemenger BBDO is collaborating on the project with researchers from the University of Tasmania. Their stated intention is to hold the world accountable for Earths future by creating a device that records and stores data about how we handle the climate crisis.

If the worst is to happen and as a civilization we crash as a result of climate change, this indestructible box will be there and will record every detail of that, said Jim Curtis, executive creative director at Clemenger BBDO. So whoevers left, or whoever finds it afterwards, learns from our mistakes. Not to be too grim or anything.

The box will have a casing of three-inch-thick steel and be topped with solar panels, which will provide energy for the electronics inside, namely computers and storage drives set up to collect data on climate change. An algorithm will regularly scrape the internet for this data based on 500 different metrics, including things like atmospheric CO2 levels, temperature changes on land and in the oceans, population fluctuations, energy consumption, and policy changes that may impact the environment.

According to CNN, developers estimate the box has the capacity to store enough data for three to five decadesso unless that number increases many-fold, the world will have to end pretty soon for this thing to serve its intended purpose. Researchers are reportedly working on expanding the systems storage capabilities, which seems pretty key to its utility. One option that could make sense is to only store data for a given timeframe, i.e. delete anything over 20 years old to make space for new informationor, only store the headlines and stories that got the most press within a given year, as those will likely be the most significant and relevant anyway.

Who will use the data and how theyll access it in the hopefully distant future is another key detail still being ironed out. It is impossible to anticipate who or what will find [the box], but it can be assumed that it will not be of any use unless it is discovered by someone or something that is intelligent and civilized, with the capability of understanding and interpreting basic symbolism, said Jonathan Kneebone, director of the artistic collective Glue Society, which is involved with the project.

Depending what it is that leads to humanitys ultimate demise, a box made of steel may not be as resilient as its creators are banking on. Could it survive an asteroid impact? A massive flood? How about an earthquake? (In fairness, these are all pretty unlikely in this location; Tasmania was chosen partly for its geologic stability).

Large-scale efforts to curb or repair climate change are proliferating; the last four months alone have brought news of cloud seeding, solar geoengineering, the worlds biggest direct air capture facility, real-time tracking of global carbon emissions, and a supercomputer creating a digital twin of Earth. Meanwhile, new solar farms and wind turbines continue to spring up, and fusion power is inching closer to becoming a reality.

You cant say we arent trying.

But there are a lot of cars on the worlds roads, a lot of people and manufacturing facilities and server hubs gobbling up power (among an endless list of other gobblers), and extensive damage to our atmosphere, oceans, and forests that, for all our best efforts, will be very hard to undo. Meanwhile, the global population continues to grow, as does demand for goods and services that require energy to be produced and delivered.

One thing is clear: humanity isnt going down without a fight. But whether well be able to science the sh*t out of this remains to be seen. A black box storing all the dirty details doesnt seem like the most helpful of tools, but it would make it easier for our great-great-great-great (great, great) grandchildren to figure out where we went wrong.

Construction of Earths Black Box is expected to be complete in early 2022.

Earth Will Soon Have a Black Box to Chronicle Humanity's Downfall - Singularity Hub

AI is exerting an ever greater influence on our lives, which is leading to growing concern over whether we can trust it to act fairly and reliably. Ethical hackers, AI audits, and bias bounties could help us keep a lid on the potential harms, say researchers.

Theres increasing awareness of the dangers posed by our reliance on AI. These systems have a worrying knack for picking up and replicating the biases already present in our society, which can entrench the marginalization of certain groups.

The data-heavy nature of current deep learning systems also raises privacy concerns, both due to their encouragement of widespread surveillance and the possibility of data breaches. And the black box nature of many AI systems also makes it hard to assess whether theyre working correctly, which can have serious implications in certain domains.

Recognition of these issues has led to a rapidly expanding collection of AI ethics principles from companies, governments, and even supranational organizations designed to guide the developers of AI technology. But concrete proposals for how to make sure everyone lives up to these ideals are much rarer.

Now, a new paper in Science proposes some tangible steps that the industry could take to increase trust in AI technology. A failure to do so could lead to a tech-lash that severely hampers progress in the field, say the researchers.

Governments and the public need to be able to easily tell apart between the trustworthy, the snake-oil salesmen, and the clueless, lead author Shahar Avin, from Cambridge University, said in a press release. Once you can do that, there is a real incentive to be trustworthy. But while you cant tell them apart, there is a lot of pressure to cut corners.

The researchers borrow some tried and tested ideas from cybersecurity, which has grappled with the issue of getting people to trust software for decades. One popular approach is to use red teams of ethical hackers who attempt to find vulnerabilities in systems so that the designer can patch them before theyre released.

AI red teams already exist within large industry and government labs, the authors note, but they suggest that sharing experiences across organizations and domains could make this approach far more powerful and accessible to more AI developers.

Software companies also frequently offer bug bounties, which provide a financial reward if a hacker finds flaws in their systems and tells them about it privately so they can fix it. The authors suggest that AI developers should adopt similar practices, offering people rewards for finding out if their algorithms are biased or making incorrect decisions.

They point to a recent competition Twitter held that offered rewards to anyone who could find bias in their image-cropping algorithm as an early example of how this approach could work.

As cybersecurity attacks become more common, governments are increasingly mandating the reporting of data breaches and hacks. The authors suggest similar ideas could be applied to incidents where AI systems cause harm. While voluntary, anonymous sharingsuch as that enabled by the AI Incident Databaseis a useful starting point, they say this could become a regulatory requirement.

The world of finance also has some powerful tools for ensuring trust, most notably the idea of third-party audits. This involves granting an auditor access to restricted information so they can assess whether the owners public claims match their private records. Such an approach could be useful for AI developers who generally want to keep their data and algorithms secret.

Audits only work if the auditors can be trusted and there are meaningful consequences for a failure to pass them, though, say the authors. They are also only possible if developers follow common practices for documenting their development process and their systems makeup and activities.

At present, guidelines for how to do this in AI are lacking, but early work on ethical frameworks, model documentation, and continuous monitoring of AI systems is a useful starting place.

The AI industry is also already working on approaches that could boost trust in the technology. Efforts to improve the explainability and interpretability of AI models are already underway, but common standards and tests that measure compliance to those standards would be useful additions to this field.

Similarly, privacy-preserving machine learning, which aims to better protect the data used to train models, is a booming area of research. But theyre still rarely put into practice by industry, so the authors recommend more support for these efforts to boost adoption.

Whether companies can really be prodded into taking concerted action on this problem is unclear. Without regulators breathing down their necks, many will be unwilling to take on the onerous level of attention and investment that these approaches are likely to require. But the authors warn that the industry needs to recognize the importance of public trust and give it due weight.

Lives and livelihoods are ever more reliant on AI that is closed to scrutiny, and that is a recipe for a crisis of trust, co-author Haydn Belfield, from Cambridge University, said in the press release. Its time for the industry to move beyond well-meaning ethical principles and implement real-world mechanisms to address this.

New infosec products of the week: December 10, 2021 - Help Net Security

In 2020, scientists made global headlines by creating xenobotstiny programmable living things made of several thousand frog stem cells.

These pioneer xenobots could move around in fluids, and scientists claimed they could be useful for monitoring radioactivity, pollutants, drugs, or diseases. Early xenobots survived for up to ten days.

A second wave of xenobots, created in early 2021, showed unexpected new properties. These included self-healing and longer life. They also showed a capacity to cooperate in swarms, for example by massing into groups.

Last week, the same team of biology, robotics, and computer scientists unveiled a new kind of xenobot. Like previous xenobots, they were created using artificial intelligence to virtually test billions of prototypes, sidestepping the lengthy trial-and-error process in the lab. But the latest xenobots have a crucial difference: this time, they can self-replicate.

The new xenobots are a bit like Pac-Man. As they swim around they can gobble up other frog stem cells and assemble new xenobots just like themselves. They can sustain this process for several generations.

But they dont reproduce in a traditional biological sense. Instead, they fashion the groups of frog cells into the right shape, using their mouths. Ironically, the recently extinct Australian gastric-brooding frog uniquely gave birth to babies through its mouth.

The latest advance brings scientists a step closer to creating organisms that can self-replicate indefinitely. Is this as much of a Pandoras Box as it sounds like?

Conceptually, human-designed self-replication is not new. In 1966, the influential mathematician John Von Neumann discussed self-reproducing automata. Famously, Eric Drexler, the US engineer credited with founding the field of nanotechnology, referred to the potential of grey goo in his 1986 book Engines of Creation. He envisaged nanobots that replicated incessantly and devoured their surroundings, transforming everything into a sludge made of themselves.

Although Drexler subsequently regretted coining the term, his thought experiment has frequently been used to warn about the risks of developing new biological matter.

In 2002, without the help of AI, an artificial polio virus created from tailor-made DNA sequences became capable of self-replication. Although the synthetic virus was confined to a lab, it was able to infect and kill mice.

The researchers who created the new xenobots say their main value is in demonstrating advances in biology, AI, and robotics.

Future robots made from organic materials might be more eco-friendly, because they could be designed to decompose rather than persist. They might help address health problems in humans, animals, and the environment. They might contribute to regenerative medicine or cancer therapy.

Xenobots could also inspire art and new perspectives on life. Strangely, xenobot offspring are made in their parents image, but are not made of or from them. As such, they replicate without truly reproducing in the biological sense.

Perhaps there are alien life forms that assemble their children from objects in the world around them, rather than from their own bodies?

It might be natural to have instinctive reservations about xenobot research. One xenobot researcher said there is a moral imperative to study these self-replicating systems, yet the research team also recognizes legal and ethical concerns with their work.

Centuries ago, English philosopher Francis Bacon raised the idea that some research is too dangerous to do. While we dont believe thats the case for current xenobots, it may be so for future developments.

Any hostile use of xenobots, or the use of AI to design DNA sequences that would give rise to deliberately dangerous synthetic organisms, is banned by the United Nations Biological Weapons Convention and the 1925 Geneva Protocol and Chemical Weapons Convention.

However, the use of these creations outside of warfare is less clearly regulated.

The interdisciplinary nature of these advances, including AI, robotics, and biology, makes them hard to regulate. But it is still important to consider potentially dangerous uses.

There is a useful precedent here. In 2017, the US national academies of science and medicine published a joint report on the burgeoning science of human genome editing.

It outlined conditions under which scientists should be allowed to edit human genes in ways that allow the changes to be passed on to subsequent generations. It advised this work should be limited to compelling purposes of treating or preventing serious disease or disability, and even then only with stringent oversight.

Both the US and UK now allow human gene editing under specific circumstances. But creating new organisms that could perpetuate themselves was far beyond the scope of these reports.

Although xenobots are not currently made from human embryos or stem cells, it is conceivable they could be. Their creation raises similar questions about creating and modifying ongoing life forms that require regulation.

At present, xenobots do not live long and only replicate for a few generations. Still, as the researchers say, living matter can behave in unforeseen ways, and these will not necessarily be benign.

We should also consider potential impacts on the non-human world. Human, animal, and environmental health are intimately linked, and organisms introduced by humans can wreak inadvertent havoc on ecosystems.

What limits should we place on science to avoid a real-life grey goo scenario? Its too early to be completely prescriptive. But regulators, scientists, and society should carefully weigh up the risks and rewards.

Iridia to Double Headcount and Footprint to Accelerate Growth

Amy Kruse of Prime Movers Lab to Join Board of Directors

SAN DIEGO, Dec. 14, 2021 (GLOBE NEWSWIRE) -- Iridia, Inc., a pioneer in DNA-based data storage, today announced that it has closed a follow-on round of $6 million with Prime Movers Lab. Amy Kruse, General Partner of Prime Movers Lab, will be joining Iridias Board of Directors effective immediately. This round is preceded by an oversubscribed $24 million financing, which will facilitate the companys ability to double its headcount and physical footprint. Proceeds from this follow-on round will fund further validation of the companys technology and the development of working prototypes.

Iridias disruptive technology is designed to integrate the writing, storage, and read back of massive amounts of data using synthetic DNA as the storage media. This combination of functionality will significantly increase data density and durability compared to conventional approaches, while dramatically reducing the physical and carbon footprints of commercial data centers around the world.

We are extremely excited to have Prime Movers Lab on board as an equity partner, as well as the addition of Amy to our board, said Murali K. Prahalad, Ph.D., President and CEO of Iridia. They bring a tremendous amount of strategic expertise in deploying complex technologies into real-world environments, as well as the potential for participating in additional financing rounds.

Amy Kruse brings over 15 years of experience working with emerging companies. She is currently a General Partner at Prime Movers Lab where she leads their life sciences investments. Previously, Amy served as the Chief Scientific Officer at Optios, as well as VP and Chief Technology Officer at Cubic Global Defense overseeing innovation and the R&D portfolio across the entire defense enterprise. Early in her career, she served as a government civilian program manager at DARPA. Amy is a Founding Member of the Loomis Innovation Council and a Guest Lecturer for Singularity University. She earned a BS in Cell and Structural Biology and a Ph.D. in Neuroscience from University of Illinois Champaign-Urbana, where she was awarded an NSF Graduate Fellowship.

Story continues

As the volume of data being generated every day increases at exponential rates, the demand for storing that data is also skyrocketing. We think DNA provides the most exciting opportunity for solving the data storage problem, and Iridia has the right team and approach for the vast and underserved data storage space, said Kruse. Iridias proprietary biochemistry and system architecture will be more energy-efficient, cost-competitive, and secure than competing data storage solutions.

Data generation is expanding exponentially. The Economist predicts there will be up to 1 trillion computerized, networked devices by 2035. The worlds ability to generate digital data is far exceeding our ability to store it, thus significantly constraining the power of big data analytics. Currently, over 20 zettabytes of digital data are lost each year due to storage capacity limitations. To put this in context, to store one zettabyte of data would require more than one billion, one terabyte hard drives. And if technologies such as flash memory were used to meet this growing need, the resultant archive would need up to 100 times the worlds available supply of microchip-grade silicon by 20401.

Iridias unique and patented method of data storage integrates semiconductor technology with a disruptive enzyme-based chemistry to add DNA-based bits representing 0s and 1s in a programmable fashion. This offers the potential to add orders of magnitude more storage capacity compared to current archival technologies such as magnetic tape and hard-drives paving the way for commercially viable DNA data storage solutions.

As the industry focus on DNA data storage expands, Iridia will be well positioned with a solution designed specifically for the modern data center, said Jay T. Flatley, Chairman of the Board of Iridia and Chairman and former CEO of Illumina. This additional funding will enable the company to accelerate development of working prototypes, an important milestone on the path to commercialization and adoption.

Iridia Raises $6 Million in Follow-on Equity Funding for Development of Industrys First DNA-based Memory Chips - Yahoo Finance

In science fiction movie, The Core, an intrepid crew journeys to the center of the Earth in a vessel that melts through the planets crust and mantle with a giant laser. Drilling startup, Petra, was founded on a similar idea. But they had a problem.

What do you do with all the lava?

In The Core, you dont do anything with it because its science fiction, and the vessel, Virgil, is made of a fanciful material called unobtainium that not only withstands extreme heat and pressure but also converts it into energy that somehow further reinforces Virgils hull.

Lacking unobtainium, Petra pivoted.

To be clear, their first prototype didnt use lasers, rather it melted rock with a plasma torch. But when the team realized disposing of all that magma was a bit of an issue, they decided to try pulverizing the rock with superheated gas instead.

The new rig is a robot, semi-automated with machine vision, that tunnels through solid rock without touching it. (Though the drilling itself is contact-free, the robot touches the surface with sensors.)

In a recent trial of the tech, the Petra team decamped to Minnesota to pit their tunneling robot, Swifty, against Sioux Quartzite, one of the worlds toughest rock types. After setting Swifty up and hitting the gas, they made quick work of a 20-foot demonstration bore hole.

we averaged an astounding one-inch-per-minute in a geology usually excavated by dynamite, said Ian Wright, Petras CTO and a Tesla cofounder, in a press release. No tunneling method has been able to tunnel through this kind of hard rock until now. Petras achievement is due to Swiftys thermal drilling method which efficiently bores through rock without touching it.

Next stop, the center of the Earth? Not so much. The company has some fairly specific plans in mind for the near future.

While other startups, like Elon Musks Boring Company, focus on tunnels big enough for roads, Petra is aiming to hollow out tunnels 20 to 60 inches in diameter to bury utilities. (Though Wright cofounded Tesla, he says he wasnt involved in the Boring Company.)

Cofounder and CEO Kimberly Abrams was motivated to start a company to tackle the challenge in 2018 when downed power lines sparked the devastating Paradise wildfire in California. That fire, and others since, led California utility PG&E to pledge to bury 10,000 miles of power lines in the riskiest areas at an estimated cost of $15 billion to $30 billion. With $65 billion from the recently passed $1.2 trillion infrastructure bill earmarked for grid improvements, demand for alternative boring technologies may grow in coming years.

What we realized in 2018 was that some of the most disaster-prone areas of the country were also the areas that had these nightmare geologies that no utility company or construction company could bore utility tunnels throughgeologies of granite and basalt that stopped tunneling projects in their tracks and that cause billions of dollars of cost overruns, Abrams said to Forbes.

Expense is a reason utilities havent buried more power lines in the past. John Fluharty, a contractor who works with utility companies to install pipelines, told Wired that its costs five times more to bury lines as opposed to stringing them pole-to-pole above-ground and up to 20 times as much when the buried lines need to travel through hard rock.

Abrams said the company think their tech could reduce costs by 50 to 80 percent.

The process, called thermal spallation drilling, isnt new, but has yet to be widely commercialized. Petra isnt sharing technical details, citing competitive concerns. Generally, though, Swifty breaks rock into small pieces with a jet of gas heated to 1,800 degrees Fahrenheit and uses a vacuum to clear the shattered remains from the tunnel. The non-contact method makes quick work of hard rock without suffering broken cutter heads.

Its much too early to know how much of an impact Petras technology will have, but the company, which emerged from stealth only recently, has raised $33 million to find out. Up next are tests out in the field on materials like granite, dolomite, limestone, and basalt.

Burying utilities, power lines in particular, would likely take many years to complete, even after new innovations prove themselves. But it seems a worthy project.

In addition to reducing the risks of disasters like wildfires, burying utilities infrastructure can also reduce longterm maintenance costs. And the grid is only likely to grow as demand for renewable energy and electric vehicles increases.

But besides practical and safety benefits, wouldnt it be just lovely to hide the mess of cables electrifying the planet, too?

This Robot Tunnels Through Solid Rock by Blasting It With a Jet of Superheated Gas - Singularity Hub

Raise your hand if you live in a stable universe thats rapidly expanding to support its own vastness. Not so fast Earthlings. We might have an end-game level crunch-time problem on our hands.

Up front: Everyones heard of the Big Bang. And long-time Neural readers will certainly be familiar with the Big Rip. But its long past time we talked about the Big Crunch.

This hypothetical event would be our universes final act. It would essentially be the exact opposite of the Big Bang.

Our universe would collapse in on itself until it became an infinitesimal singularity a single point containing everything that ever was.

Background: The astrophysics world is all atwitter right now on the heels of the recent discovery of yet another galaxy that apparently contains low or no dark matter.

This is a lot like cutting open an apple and realizing that instead of its delicious, juicy pulp, it contains well, nothing.

It wouldnt make much sense because we expect there to be something inside the apple to help it keep its physical form. Even air would be something. Finding nothing would be a difficult pill to swallow.

Such a discovery would force us to rethink the physics of apples, much like Sir Isaac Newton did in the summer of 1666.

More background: The Big Crunch is, of course, only theoretical. But the recent discovery of these dark matter-free galaxies could lend some credence to the idea.

This is because many scientists believe that dark energy and dark matter make up the majority of the universe.

We believe our universe started expanding the moment the Big Bang happened and hasnt stopped since. And we believe that this expansion is fueled by dark energy.

Dark matter (theoretically) works diametrically to dark energy. Its believed to be a force that holds space together.

Its a bit more complicated than all that, but the important part is that we can only observe these forces indirectly. Thats why theyre called dark, we cant actually see them, but astrophysics simulationsdont tend to work unless we account for them.

How it all ends: Obviously, if the entire universe were once again reduced to a singularity, as scientists believe it was just before the Big Bang, everything in it would be rearranged. We cant say it would be destroyed because it would all still be there, it would just be infinitely tiny.

Its a pretty good bet than anything living wouldnt survive the Big Crunch. And the lack of dark matter in observable galaxies could be a major cause for concern.

This is because, as astrophysicist Paul Sutter wrote in an article published earlier today, whether or not the universe itself is actually stable remains an open question.

An unstable or even mostly stable universe could be potentially catastrophic for the future of its inhabitants. This may have something to do with the fact that the universe hates entropy.

According to Sutter:

The apparent metastability of the quantum fields of the universe is a little unsettling. Although it could mean that the universe could persist for billions, even trillions, of years without anything going wrong at all, it could also mean that the universe is already beginning to transform.

This sounds like a form of error-correction at a fundamentally universal level. Sutter hypothesizes such a transformation could be entirely mundane, leaving our observations of the universe mostly unchanged. However, they also posit that it could radically alter the underlying physics of the universe to such a degree that chemistry and atomics as we understand them no longer function viably.

Quick take: The lack of dark matter in nearby galaxies is a cause for concern because, currently, we cant explain why it isnt there. Like the pulp inside of an apple, we expect to see dark matter inside of a galaxy when we use technology to penetrate its outer skin.

Ultimately, this could be nothing. Science is hard and sometimes the answers to big exciting questions are boring. Maybe the dark matter is there and we just arent looking for it the right way.

But the scientists are convinced theyve got it right, at least as right as any other observations on distant galaxies have been.And, if they are right about the missing dark matter, then its possible the instability of the universe could be a big problem.

If the Big Crunch were to eventually happen, there should be a single moment where the universes expansion away from its original singularity converts into a reduction toward an infinitesimal point again.

This process could have already begun.

According to Sutters article:

All it would take is one little shake in the wrong direction, in some random patch of the universe, where the Higgs falls apart and the underlying quantum fields find a new, more stable configuration. That region of new universe would then propagate outward at nearly the speed of light through the old universe.

Sutter isnt necessarily referring to the idea of the Big Crunch, but the ideas they present lend themselves to the possibility of such an end for our universe.

The Big Crunch, or some other universe-altering event, could be happening right now. And wed have no way of knowing when its effects would reach our neck of the cosmos. It could be trillions of years from now orbefore you finish reading this sentence.

Whew! Glad were all still here.

The good news is that if the universe can go from Big Bang to Big Crunch once, it seems perfectly plausible to assume it can do it again. So if we all snuff it in an instant, we can take solace in the fact that the stardust were made out of could once again burn brightly after the next Big Bang populates the cosmos with stellar entities again.

Maybe our entire universe is just a time crystal expanding and contracting inside a giant quantum computer.

Can galaxies without dark matter tell us how the universe ends? - The Next Web

From a roadtrip through the Australian desert, to traversing treacherous terrain in New Zealand, here are a collection of new books that explore the highs and lows of travel whilst celebrating extraordinary journeys.

By Chance the Future is Amy Rudders debut novel that tells a story of stepping out into the world and trusting youll know what to do when you get there.

Blending travel writing, philosophical treatise, self-deprecating comedy with a dose of political criticism, the book takes you on a journey back in time to the year 2001.

The author highlights both our very human hypocrisy and genuine attempts to connect, and the singularity and the sameness of our youthful adventures as we attempt to individuate from our families and countries of origin.

While the story is focused on life at the turn of the century, it makes you reflect on where we were 20 years ago in comparison to where we are today at a distance and with hindsight.

Uprising by Nic Low is a riveting blend of nature writing, indigenous storytelling and great adventure through New Zealands Southern Alps.

Best described as a part-guide and part-memoir, the book follows Low on a journey of discover as he retraces the paths and stories of his ancestors.

Having grown up hearing stories from the mountains on his fathers European side, the author sets out to understand how his Maori ancestors on his mothers side knew that same terrain before Europeans arrived in New Zealand.

Throughout the gripping adventure, the author meets with tribal leaders to try and understand how his forebears saw and traversed the land. He then sets out on an expedition across treacherous terrains using only the traditional oral maps of his ancestors as his guide.

Inspired in part by a bundle of wartime love letters from the authors English-born father to her mother, the 300-page memoir dissects what it means to be a Chutney Mary and the complexities and nuances of having mixed blood.

Throughout the book, the Melbourne-based author and social researcher shares some fascinating moments from her own life, having worked for over two decades in India. It also provides a wealth of observation, knowledge and insight; from horrendous accounts of the 1947 partition, to a dowry murder, to chronic corruption.

Engaging and beautifully written, A Touch of India leaves readers with a richer understanding of middle-class India, whilst providing a touch of history, travel and textiles along the way.

Road Tripping with Pearl Nash is Poppy Nwosus third romantic novel for young adults. It follows protagonist Pearl Nash on a road trip during the summer holidays before her final year of school, exploring friendship, love, grief and the courage to move forward in life.

While the whirlwind road trip through South Australias coastal desert region was supposed to save Pearls slowly disintegrating friendship with her best friend, nothing seems to go to plan and the protagonist ends up in the middle of nowhere beside a boy with an endlessly irritating attitude but a great smile.

Full of adventure, humour and heart, Road Tripping with Pearl Nash is a story about home and family, about breaking apart and fusing together, and, of course, about love.

BTS V is known for his soulful jazz vocals on songs like Stigma and Singularity. Last Christmas, this artist shared his love for several jazz artists, even revealing that hes been listening to two or three holiday LPs.

Heres what we know about the Inner Child singer, Kim Taehyung.

Along with Jin, Suga, J-Hope, RM, Jimin, and Jungkook, V is one of the vocalists behind songs like Permission to Dance, Life Goes On, and Butter. He appears as a dancer, singer, and songwriter in BTS, even acting as a visual consultant for the Be (Deluxe Edition) photoshoots.

Outside of his work with BTS, the singer sometimes releases solo music inspired by the winter and snow. In 2019, that included the all-English track Winter Bear. He released Snow Flower on Christmas Eve in 2020, sharing his love for the holiday season that same year.

In 2020, the BTS members participated in solo interviews, discussing their latest album Be (Deluxe Edition) and the success of their first all-English single Dynamite. Because it was around the holidays, it made sense that V shared he was listening to Christmas music.

Well, Im listening to LPs lately. Its getting to be Christmas season, and I love snow, so I bought two or three Christmas LPs to listen to, V said during the interview with Weverse Magazine. Im also listening to old jazz songs by Frank Sinatra, and Sammy Davis Jr. Frank Sinatra is cool, like chilled wine; Sammy Davis Jr. is crazy talented.

V wouldnt be the only BTS member to share his love for the holiday season, as these K-pop idols often wish fans a happy holiday during live streams and on social media. They even performed Santa Claus is Comin to Town in conjunction with the Disney Holiday Singalong.

V often shares his love for all things vintage, including movies like The Godfather and The Shawshank Redemption. V added that Sinatra and Davis Jr. were artists he found cool during the same Weverse interview.

Those two were also a big inspiration to me while we were working on Dynamite, V said. Sinatra has all this jazzy body language, but he also threw some disco in there. And I imagined how Sammy Davis Jr. might dance if there were a mic on stage and he had to dance around it.

Of course, V often shares his love for todays top artists. In one Twitter video, he played with a tiger puppet while listening to The View by Surfaces. In his Spotify playlist, V included songs by Anthony Joseph, David Halliday, and others.
