Watch: Chimpanzees give each other first aid
Chimpanzees use forest first aid to treat wounds and leaves to wipe their bottoms, scientists have found.
A study, led by a University of Oxford researcher, catalogued the apes dabbing leaves on their wounds, or applying sap and chewed up plant matter to the injuries.
They treated the wounds of other members of their group as well as their own.
The research, published in Frontiers in Ecology and Evolution, adds to a growing body of evidence on how apes take care of themselves in the wild.
Dr Elodie Freymann, of Oxford University's School of Anthropology, said: 'We humans like to fancy ourselves unique in lots of different ways. And I think for a long time, we thought that healthcare was one of those ways in which we humans are special.'
She said there was 'a whole behavioural repertoire that chimpanzees use when they're sick or injured in the wild – to treat themselves and to maintain hygiene'.
Dr Freymann added: 'Some of these include the use of plants that can be found here. The chimpanzees dab them on their wounds or chew the plants up, and then apply the chewed material to the open injury.'
Footage of the apes treating each other was included in the study, conducted in Uganda's Budongo Forest, as well as years of observations noted by field staff, researchers and visitors.
A log book dating back to the 1990s was found to include anecdotal accounts of the apes dabbing wounds, removing snares and cleaning themselves with leaves after defecating, or mating.

Dr Freymann previously reported that chimpanzees appeared to seek out specific medicinal plants to treat their ailments.
A 2024 paper saw researchers test the plants eaten by sick or wounded chimps and found that they often had antibacterial or anti-inflammatory properties.
Meanwhile, an orangutan was recorded applying the leaves of a plant commonly used in traditional medicine to a cut on its face, seemingly to hasten healing.
Gorillas, chimpanzees and bonobos have also been recorded swallowing whole leaves from Aspilia plants to get rid of worms.
In 2022, a community of chimpanzees in Gabon was seen putting insects onto their open wounds, potentially as a form of first aid.
Chimpanzees in captivity have long been observed giving each other basic medical care, including removing splinters and cleaning each other's teeth.
Finding the same tendency in the wild means 'additional evidence for empathic capacities in our closest evolutionary relatives', researchers concluded.
They said it was still not clear how the behaviour was learnt or transmitted and 'establishing this will be an important step for understanding whether any components of non-human healthcare systems are influenced by local medicinal cultures'.
Studying ape healthcare could even lead to the discovery of medicines, scientists believe.
Dr Freymann told the BBC: 'The more we learn about chimpanzee behaviour and intelligence, the more I think we come to understand how little we as humans actually know about the natural world.
'If I were plopped down here in this forest with no food and no medicine, I doubt that I'd be able to survive very long, especially if I were injured or sick.
'But chimpanzees thrive here because they know how to access the secrets of this place, and how to find all they need to survive from their surroundings.'

Scientists Just Launched the First Quantum Computer Into Space
The world of quantum computing has barged into a new frontier: space. A tiny quantum computer housed in a satellite is now in orbit around Earth, ScienceNews reports, residing some 330 miles above our planet after being launched aboard a SpaceX rocket last month. It's a trailblazing experiment intended to test how well these delicate devices can survive the extreme conditions of space, where they could allow satellites to quickly and efficiently perform intense calculations on their own. The experiment is also a ripe opportunity to put some fundamental physics principles to the test, according to project lead Philip Walter, a physicist at the University of Vienna. "Being the first here also means we have the duty and privilege to investigate if things operate in the way as we'd be used to on the ground," Walther told ScienceNews. Built in just eleven days, the idea behind the device was to "shrink a whole quantum laboratory down to the size of a satellite payload," Walter said in a statement before the launch. It's safe to say that they delivered on that premise. At a size befitting its quantum ambitions, the finished device is less than a gallon in volume, weighs just 20 pounds and some change, and will on average use only 10 watts of power, and no more than 30. The potential — and we stress potential — advantage of using a quantum computer in space is that it can perform "edge computing," or process data directly on the satellite. Otherwise, that data needs to be beamed down to Earth, put through calculations on a ground-based computer, and sent back up, which expends extra time and energy. Most importantly, they can theoretically perform specific types of calculations faster than classical computers, making them an enticing option in fields such as machine learning. Or at least, that's what they promise to do eventually. This device in particular is a photonic quantum computer, which uses individual photons — the massless particles that make up light — to represent units of information called qubits. A qubit, unlike a classical, electron-based bit, can be a 1 or 0 at the same time using a spooky quantum property known as superposition. As an added bonus, quantum computers have shown that they can potentially be more energy efficient. That's great news for satellite missions, which operate with extremely tight energy budgets. The fuel they launch with is essentially what they work with. Quantum computing in space may sound like a no-brainer, then — we've been testing quantum communications up there for years now — but it's important to remember that it still highly experimental tech with a whole lot unrealized potential and few applications outside of a laboratory. Though there have been pretenders to the throne in the past, no one has yet achieved clear "quantum supremacy," a point where a quantum computer can perform calculations that a classical one can't. One of the biggest issues in the field is that a quantum computer typically require a meticulously controlled environment to function, because even the slightest disturbance can cause a qubit to lose its quantum state, and thus, its information. In space, where there's no protective atmosphere, the computer's electronics are at the mercy of extreme temperature swings and blasts of cosmic radiation. The good news is that Walter's team has confirmed that its hardware is now operational, he told ScienceNews. Its long-term resilience will have to be borne out, but it's an encouraging start. Once its work is finished, the satellite will make a controlled re-entry into the Earth's atmosphere, where it will meet a fiery — but safe — end. Until then, it'll hopefully keep itself busy by taking images of Earth and crunching the numbers. More on quantum computing: Chinese Hackers Use Quantum Computer to Break Military Grade Encryption

Yoga, Zumba or HIIT? The best way to exercise, based on your personality type
Curating your fitness routine to better match your personality could help you get the most out of your workouts, a new study shows. The paper, published last month in Frontiers in Psychology, shows that certain personality traits may indicate which type of exercises people enjoy and how likely they are to stick with them. "We found that our personality can influence how we engage with exercise, and particularly which forms of exercise we enjoy the most," Flaminia Ronca, one of the study's co-authors and an associate professor at University College London, said in a press release. "It's OK if we don't enjoy a particular session," Ronca said. "We can try something else." Ronca and her fellow researchers recruited 132 adults, and placed them into two groups. One group was told to follow at-home workouts of cycling and strength training, and the other group was asked to follow their usual routines. Participants were given a questionnaire to determine their personality type and stress levels. By the end of the study, a total of 86 participants completed their group's assignment and surveys which asked which workouts they enjoyed the most before and after the experiment began. The paper focused on the Big Five personality traits used in psychology: Here are the workouts that each personality type found the most exciting. People who scored high in extraversion seemed to enjoy high-intensity workouts (HIIT) and team sports. Some exercises that extroverts should try are: Those who got high scores for conscientiousness tended to like goal-oriented exercises. They really enjoyed activities like training for a marathon or joining a run club. Exercises that conscientious people should explore are: People that scored high in neuroticism, or those who often experienced mood swings and anxiety, preferred light, one-on-one workouts. "This group might appreciate being given space for independence and privacy during an exercise program," Ronca said. Anxious people may benefit from having private sessions with a personal trainer or a Pilates instructor, and would likely avoid group classes. People who fall into the group of openness and agreeableness liked fun workouts and looked for variety. Exercises for open-minded and agreeable people to consider are: It is not at all surprising that introverts preferred to work out on their own and in their homes. Some exercises that introverts would likely gravitate towards are:

Bronze Age Humans Got High on Psychoactive Betel Nuts
Long before Ethiopian monks in the 9th century discovered that coffee tree fruit helped them stay awake during evening prayer (according to legend, anyway), communities in Southeast Asia have been chewing betel nuts—the seeds of the areca palm and a stimulant that heightens people's alertness, energy, euphoria, and relaxation—since antiquity. But new research indicates that betel nut chewing has been practiced for even longer. By studying ancient dental plaque from Bronze Age individuals in Thailand, an international team of researchers suggests that people were consuming the stimulant 4,000 years ago. This novel approach paves the way for future investigations of ancient behaviors in the absence of traditional archaeological evidence. 'We identified plant derivatives in dental calculus from a 4,000-year-old burial at Nong Ratchawat, Thailand,' Piyawit Moonkham, an anthropological archaeologist at Chiang Mai University and first author of the study published yesterday in Frontiers in Environmental Archaeology, said in a statement. Dental calculus, also called tartar, is hardened dental plaque. 'This is the earliest direct biomolecular evidence of betel nut use in south-east Asia.' Moonkham and colleagues analyzed 36 dental calculus samples from six individuals from Nong Ratchawat, a Bronze Age archaeological site in central Thailand. The team also produced their own betel liquid samples to investigate the interactions between ingredients and make sure their analysis could accurately detect the psychoactive compounds. 'We used dried betel nut, pink limestone paste, Piper betel leaves, and sometimes Senegalia catechu bark and tobacco. We ground the ingredients with human saliva to replicate authentic chewing conditions,' Moonkham explained. 'Sourcing materials and experimentally 'chewing' betel nuts to create authentic quid samples was both a fun and interesting process.' A betel quid is a chewing mixture consisting of the areca nut and other ingredients, such as those listed above. It's worth mentioning that a heavy use of betel nuts can eventually lead to health risks such as oral cancers and heart disease. Ancient Egyptians Mixed Psychedelics, Bodily Fluids, and Alcohol for Rituals, Scientists Confirm The team's analysis revealed traces of arecoline and arecaidine in three of the samples, all from the same individual—organic compounds present in betel nuts as well as coffee, tea, and tobacco, which can have a significant impact on a person's physiology. In other words, betel chewing has likely existed for at least 4,000 years. 'In essence, we've developed a way to make the invisible visible—revealing behaviors and practices that have been lost to time for 4,000 years,' said Shannon Tushingham, senior author of the study and associate curator of anthropology at the California Academy of Sciences. Furthermore, 'the presence of betel nut compounds in dental calculus does suggest repeated consumption, as these residues become incorporated into mineralized plaque deposits over time through regular exposure.' While consistent betel juice chewing usually stains teeth, the researchers did not identify any such staining. They suggest that this could be due to different consumption methods, ancient teeth cleaning practices, or processes that prevented the stains from lasting over 4,000 years. They also didn't find any evidence indicating that the individual's burial was special compared to the others—evidence that, presumably, might have provided insight into why the individual consumed betel nuts. 'Psychoactive, medicinal, and ceremonial plants are often dismissed as drugs, but they represent millennia of cultural knowledge, spiritual practice, and community identity,' Moonkham concluded. 'Archaeological evidence can inform contemporary discussions by honoring the deep cultural heritage behind these practices.'
