Prehistoric rubbish hints that early cooks cared about flavour

In the popular imagination, a Palaeolithic lunch is a giant hunk of meat, roasted over an open fire. Science, too, has focused more on the Stone Age hunter than the ancient gatherer. But that is changing, according to Ceren Kabukcu at the University of Liverpool, UK, and her team, who analysed the charred remains of prehistoric food to expand our understanding of Palaeolithic menus1.

I hope this vial of blood contains answers because I have a nagging question - have I managed to dodge Covid?
It seems remarkable that anyone could. The virus has swept the world since it emerged in China nearly three years ago. Fresh variants have become better and better at infecting us. Even vaccines make Covid milder rather than being an impenetrable shield.

S13Does Influencer Marketing Really Pay Off?
Influencer marketing is a huge industry, with companies around the world spending billions of dollars on these partnerships. But do these investments actually pay off? To quantify the ROI of influencer marketing, the authors analyzed engagement for more than 5,800 influencer posts and identified seven key variables that drive a campaign’s effectiveness, including characteristics of both the influencer and of their individual posts. They further found that by optimizing these variables, the average brand could boost ROI by 16.6%, suggesting that many companies are designing campaigns that leave substantial value on the table. By adopting these research-backed guidelines, brands can move past anecdotal evidence to ensure that their marketing dollars go toward the partnerships and content that are most likely to offer returns.

S15Why parents are baffled by eco choices
I am preparing to embark on a challenge to parent more sustainably, and, as I stand in my kitchen to get a feel for where I might be able to make some changes, I can't help but feel I've bitten off more than I can chew. Plastic baby bottles are lined up like skittles in my cupboards; drawers are a technicolour spectacle of lurid plastic baby food pouches and individually wrapped biscuits. Tupperware and zip-lock plastic bags threaten to consume me, and there are plastic bowls, weaning pots, and baby spoons everywhere.
"Is having a baby in 2021 pure environmental vandalism?" reads one headline I come across in my research. Looking at my kitchen, I can see why.

S14Embrace Ambivalence When Making Big Career Decisions
Career inflection points are moments of potential change and transition that often evoke feelings of ambivalence: the simultaneous experience of positive and negative emotions about something. Whether prompted by sudden, external triggers (e.g., promotion opportunity or job loss) or creeping stressors that reach a tipping point, career inflection points are opportunities to reevaluate not only career decisions, but also ourselves. The studies the authors have conducted on careers, identity, and ambivalence, along with the work of other scholars, have led them to conclude that you can harness ambivalence at career inflection points to craft a more authentic and fulfilling career. Here, they discuss the effects of ambivalence — and how to use yours to your advantage.

S16As GoTo slashes 12% of workforce, massive tech layoffs hit Southeast Asia
Citra had only joined GoTo Group, the massive Indonesian ride-hailing and e-commerce decacorn, in early October 2022. So it was a shock when, a month and a half later, she discovered she’d been fired as part of mass layoffs. On November 18, the Alibaba and SoftBank-backed company, valued at some $15 billion, announced it was laying off 12% of its roughly 10,500-person permanent workforce.
“I was on sick leave, so I found out about the news from Instagram,” recalled Citra, who requested a pseudonym to avoid potential friction with the company. “Very abrupt. I know someone who joined two weeks before the announcement and was also laid off.”

S23Time is money? No, time is far more valuable. Here's how to spend money to optimize your time
Four thousand weeks is the average lifespan of a person living in the modern world. With exercise and healthy living, you may push that number out a couple of months. Then again a disease or accident may just as easily cut it short. Give or take, 4,000 weeks is all the time you have to build the life you want.
Admittedly, such framing is stark, but it’s something we all understand on a gut level: Our time is limited, and that makes it the most precious resource we have. Yet when it comes to how we use our time, it’s often in service of money.

S24Be thankful for an out-of-equilibrium Universe![]()
You couldn’t make the Universe we have today if everything were always the same. Although many philosophically favored the idea that the Universe was static and unchanging — an idea popularized in the 20th century as the Steady-State Theory — such a Universe would look vastly different than our own. Without an early, hot, dense, and more uniform past, our Universe couldn’t have expanded, cooled, gravitated, and evolved to give us what we have today: a cosmos where galaxies, stars, planets, and even life not only all exist, but appear to be quite abundant.
The reason is simple: the Universe isn’t in equilibrium. Equilibrium, which occurs when any physical system reaches its most stable state, is the enemy of change. Sure, in order to perform mechanical work, you need free energy, and that requires an energy-liberating transition of some sort. But there’s an even more fundamental problem than extracting energy: without beginning from a hot, dense state in the distant past, and then cooling and falling out-of-equilibrium, the Universe we see today wouldn’t even be possible.

S25How mind wandering helps prepare you for the future
When psychologist Jonathan Smallwood set out to study mind-wandering about 25 years ago, few of his peers thought that was a very good idea. How could one hope to investigate these spontaneous and unpredictable thoughts that crop up when people stop paying attention to their surroundings and the task at hand? Thoughts that couldn’t be linked to any measurable outward behavior?
But Smallwood, now at Queen’s University in Ontario, Canada, forged ahead. He used as his tool a downright tedious computer task that was intended to reproduce the kinds of lapses of attention that cause us to pour milk into someone’s cup when they asked for black coffee. And he started out by asking study participants a few basic questions to gain insight into when and why minds tend to wander, and what subjects they tend to wander toward. After a while, he began to scan participants’ brains as well, to catch a glimpse of what was going on in there during mind-wandering.

S18Satellite Constellations Could Harm the Environment, New Watchdog Report Says
Elon Musk’s Starlink and other satellite sources of light pollution and orbital debris should face an environmental review, the U.S. Government Accountability Office finds
Do people have a right to an unobstructed view of the heavens? For most of human history, such a question would have been considered nonsensical—but with the recent rise of satellite mega constellations, it’s now being asked again and again. Mega constellations are vast groups of spacecraft, numbering in the thousands, that could spark a multitrillion-dollar orbital industry and transform global connectivity and commerce. But the rise of mega constellations also threatens to clutter the night sky, cripple the work of some astronomers and create space debris that harms people on Earth and in space alike.

S26How to recession-proof your finances
In the wake of the COVID-19 pandemic, the stock market and economy seemed to continue stronger than ever for a while. Then, inflation started to soar. What goes up must come down, and now we’re being hit by a double-whammy of post-pandemic economic problems and new geopolitical issues, like the energy crisis.
If you’re worried about a recession coming soon, you’re not alone. 74% of U.S. consumers are thinking the same thing, and experts echo their concerns. More than two-thirds of economists expect a recession to hit the country in 2023, with some believing it may come earlier.

S17Scientists Ruin Delicious Seabass to Probe Why Some Organs Don’t Fossilize
If every living thing died right now, by some estimates only around 1 percent would become fossils. Even fewer would have any soft tissues preserved. These rare tissue fossils offer crucial clues about biology and evolution, but their formation remains mysterious. Why do scientists find fossilized intestines, for example, but never a fossilized liver?
Fossils develop when minerals replace the body parts of organisms that die and get buried in sediment, such as the mixture of mud and seawater on the ocean floor. Paleontologists are particularly fond of the fossil-building mineral calcium phosphate because it can preserve soft organs in exquisite detail—sometimes all the way down to cell nuclei. This mineral forms only under specific acidity conditions, so scientists have hypothesized for decades that differences between decaying organs’ pH levels determine which ones get preserved.

S31The long poem is just right for our confounding, fractured age | Psyche Ideas
is lecturer in English at Worcester College, University of Oxford. She is the author of Reading Time in the Long Poem: Milton, Thomson, and Wordsworth (2022).
In 1848, Edgar Allan Poe proclaimed that readers would no longer waste their time on long poems: ‘the day of these artistic anomalies is over. If, at any time, any very long poem were popular in reality, which I doubt, it is at least clear that no very long poem will ever be popular again.’ It’s not hard to see why long poems aren’t the most fashionable form of literature today. Poetry demands a sustained close attentiveness that is already difficult to achieve; long poems, which take up whole books with hundreds or even thousands of lines, combine this intense concentration with arduous duration. If reading a sonnet is hard work, why put yourself to the trouble of reading an epic?

S32The dance of the macaws | Psyche Films
A vast majority of Guatemalans are Christian, with Catholicism in the region rooted in 16th-century Spanish conquest. However, echoes of the Mayan culture that thrived in pre-Hispanic times still resonate in the country’s largely Indigenous highlands, where ancient rituals are incorporated into Christian ceremonies. The Dance of the Macaws captures one such highlands town, Santa Cruz Verapaz, where Mayan priests, elders and practitioners keep the flame of the region’s traditional religious beliefs burning.
Directed by the Guatemalan photographer and filmmaker Ricky Lopez Bruni, the short documentary chronicles the interwoven rituals of dance, worship and celebration that take place in Santa Cruz Verapaz during Catholic Holy Week. In particular, the film focuses on a ceremony with deep Mayan roots known as the Dance of the Macaws. Spanning several days and venues, the ritual is centred on a dance in which locals re-enact an ancient myth once painted on ceramic vessels.

The asteroid poses no danger to Earth, but researchers wanted to test whether this approach is feasible in case of a future threat of impact.
