Scientists pinpoint when humans started to use tools made from whale bone

Scientists have discovered the oldest evidence of humans crafting tools from whale bones, dating back roughly 20,000 years.
The bones, shaped into narrow projectiles for hunting, were found during excavations in the Bay of Biscay, near Spain and France, over a century ago. While researchers suspected the tools were ancient, their fragmented condition made accurate dating difficult.
Recent technological advancements have now enabled scientists to determine the age of the oldest tools. Analysis revealed that the bones originated from various whale species, including blue whales, fin whales, and sperm whales.
'Humans and whales have clearly been encountering one another for a long time,' said Vicki Szabo with Western Carolina University, who studies the history of whaling and was not involved with the latest research.
Scientists think that ancient humans were crafting whale bone instruments in places including the Arctic and South Pacific. There's been solid evidence of whale bone tools dating back to about 5,000 years ago, but the new research published Tuesday in the journal Nature Communications pushes the timeline back.
Ancient humans weren't necessarily hunting whales, said study author Jean-Marc Petillon with the French National Centre for Scientific Research. More likely, they were scavenging the bodies of beached whales and fashioning their dense, heavy bones into tools to hunt reindeer or bison.
The tools indicate that ancient people in the area took advantage of resources near the sea for survival. They likely also collected seashells and fished. Finding such evidence has been difficult as rising sea levels disrupt coastlines across the globe, scientists said.
'It's one more contribution to the importance of coastal environments for human groups, even in this long past," said Petillon.

Ewwwww la la! Tourists film human excrement, rats and piles of rubbish in Paris and complain of 'pee smell' in streets

Faeces splattered on the pavement. Puddles of urine collecting on the street. Piles of rubbish mounting on roads. It's not exactly what comes to mind when thinking about Paris. Visitors of the once-venerated city, described in gorgeous meter by the countless poets who travel to France 's capital for inspiration, are increasingly complaining about conditions in the city, especially on social media. One video showing faeces on the streets alongside piles of discarded rubbish, was shared to social media with the caption: 'The architecture, the history, the magic? It's real. But I'd be lying if I didn't say it also smells kinda funky, and the streets can be really dirty.' Another showed a tourist walking across the Pont du Carrousel bridge in the centre of Paris, which was uploaded with the caption: 'I don't know if it's just us wondering, but why does Paris stink like pee everywhere.' And a third showed mounds of trash in front of the eastern side of the Palais Garnier, a world famous opera house, as well as rats scurrying across the street and homeless people sleeping in the open. In recent years, the city has been forced to contend with striking bin men leading to unsavoury images of piles of rubbish in the streets. One expert pointed to the apparent propensity of French men to use streets as their own personal loos. Nicolas Fieulaine, a professor of social psychology at the University of Lyon, told the BBC in 2023: 'In the French imagination, and i'm not sure it's the case anywhere else, public urination is an option that seems available. '[It] doesn't call a person's moral character into question.' Fieulaine said the history of France's obsession with public urination began with the early 19th century public health movement in Paris, which saw massive scientific and institutional reforms in urban areas that aimed to improve the broad quality of life for French citizens. While it did end up improving public health, the professor said it also made public urination a 'taboo'. This has in turn made it attractive for men who want to feel 'power over public spaces.' 'it conveys a sense of freedom.. which excludes women. 'It's a powerful form of appropriation. Urinating somewhere is about marking one's territory.' Another problem appears to be waste management in the city. @olga_stern PARIS IN SOCIAL MEDIA VS PARIS IN REALITY ✨️Social medias show a perfect Paris with clean streets, beautiful monuments and sunny cafés. But let's be honest… the real Paris has its less glamorous side too. Trash piling up after strikes, rats on metro tracks and in parks, homeless people & beggars, crowded streets and metro, poop on the sidewalks…😱 ❤️I still love Paris, but life here isn't always like a postcard. It's messy, chaotic, imperfect, but full of soul. Would I trade it? Never. ❓️What's your real Paris experience? ✅️ this blog is about cool locations & events and life in Paris and France 🇫🇷 #paris #france #parisinreality #trash #rats #beggars #travelfrance #paristravel ♬ son original - Olga The Greater Paris area is home to around 7 million people. And every year, an estimated 17.4million people visit. All of these people leave behind an estimated 3.3million tons of waste every year. And experts have said the ageing infrastructure in the city simply isn't able to keep up. Jean Dupont, a Paris-based waste management specialist, told the What Is Green Living blog: 'The infrastructure hasn't evolved in tandem with the city's growing population and increasing consumption patterns. This mismatch creates bottlenecks, especially during peak tourist seasons.' There is also a nationwide problem with attitudes towards recycling, according to statistical data. While the average EU nation recycles 47% of its waste, France recycles just 28%. A 2021 study found that in Paris, just 60% of residents consistently sort their rubbish, with many citing confusion over the sorting system as a primary reason not to properly recycle. As a result, items that could have been recycled often end up in refuse bins that pile up in the streets. Paris has also seen a swathe of labour strikes over the past few years. @ Paris, l'amour et... la mauvaise odeur ? (Choc en ville!)

Walkouts threatened to start collective action in May and continue from July 1 to September 8, the CGT union branch representing binmen warned. This period included the Olympic Games, which ran from July 26 to August 11. Refuse workers in the Paris region demanded an extra 400 euros (£340) per month and a one-off 1,900-euro (£1,625) bonus for those working during the Olympics. And the year prior, a three-week strike by rubbish collectors against President Emmanuel Macron's unpopular pensions reform saw more than 10,000 tonnes of waste piled in Paris streets at its height. Images of the heaps of trash, some mounting several metres high, were seen around the world.

Do electric vehicles make people more carsick?

With electric cars skyrocketing in popularity around the world – in 2024, 22% of new car sales worldwide were electric vehicles, compared with 18% in 2023 – a growing body of studies and an increasing number of people have found that they feel more motion sick riding in EVs than in traditional petrol or diesel cars. Anecdotes of feeling sick in the passenger or back seat of electric cars litter social media, as do questions from wary prospective buyers. There is a scientific explanation behind why a person might feel more sick in an EV, though, according to multiple academic studies. 'Greater sickness in EVs can be attributed to a lack of previous experience, as both a driver and as a passenger, where the brain lacks accuracy in estimating the motion forces because it relies on previous experience in other types of cars,' said William Emond, a PhD student researching car sickness at the Université de Technologie de Belfort-Montbéliard in France. Though EVs are becoming more popular, combustion cars still dominate. Riders have a longer history with gas cars and so have had more time to adapt to their specific cues. If a person has spent most of their life driving a combustion engine car, their brain anticipates acceleration after the rev of the engine, a warning that they are about to experience a change in speed. In a battery-powered car, the electric motor makes no such noises. In addition to general unfamiliarity, research has found links between specific features common to electric vehicles and motion sickness. One 2024 study concluded that there were strong correlations between motion sickness severity and the seat vibrations of electric vehicles, while a 2020 study found that the lack of engine sound in an EV might be a major contributing factor to increased feelings of carsickness. 'If we are accustomed to traveling in non-EVs, we are used to understanding the car's motion based on signals such as engine revs, engine vibrations, torque, etc. Yet, traveling in an EV for the first time is a new motion environment for the brain, which needs adaptation,' Emond explains. Additionally, the regenerative braking technology used in EVs – where the motor converts the slowing car's kinetic energy into electricity that then is stored in the battery – results in low-frequency deceleration, meaning that the vehicle slows down gradually and steadily, over a relatively longer period, rather than rapidly or in quick pulses. Such low-frequency deceleration tends to be associated with higher levels of motion sickness. A 2024 study suggested the feature acted as one of the main triggers of motion sickness in electric vehicles. The study's authors wrote: 'Our results confirmed that higher levels of RB [regenerative braking] can induce MS [motion sickness].' Motion sickness is thought to be caused by a mismatch between various sensory signals the brain simultaneously receives about the body's movement. Specifically, it happens when the inner ear, which helps control balance, the eyes, and the body send conflicting information to the brain. 'Better knowledge on self-motion allows us to anticipate motion forces, which is crucial for motion sickness. Yet, when the motion forces as estimated or anticipated by the brain differ from what actually is experienced, then the brain interprets this 'neural mismatch' as a situation of conflict,' Emond said. 'If this conflict persists over time, it may surpass a threshold for triggering autonomic reactions of the body such as symptoms apparent to 'motion sickness'.' Being able to anticipate the movement of a vehicle appears to be integral to the experience of motion sickness, which is why people who are driving a car don't tend to experience symptoms. They know what is coming. The interplay between anticipation of motion and actual motion experienced may be why EVs are associated with worse motion sickness, as these vehicles provide fewer clues regarding upcoming movements. 'When discovering a new motion environment, the brain needs to habituate because there is no knowledge of previous experience in such a context. This is, for example, why almost everyone becomes sick in zero-gravity environments,' Emond says. As EV ownership continues to increase, some researchers are already looking into a solution for the cars' specific type of nausea. Several research papers have suggested that motion sickness in autonomous EVs could be treated by using visual signals, such as interactive screens and ambient lighting, or vibrational cues to allow a passenger's brain to anticipate motion changes, alleviating the lurching feeling in the back of an electric taxi.
