The COVID-19 pandemic changed the way many people approached their work across the globe. For Carnegie Mellon University Africa's Jema Ndibwile, it changed the way he viewed a completely different type of virus: a computer virus.
Longtemps considérées comme de charmantes anecdotes, les interactions sociales entre primates et autres animaux semblent en réalité largement répandues. L’étude de ce primatologue rassemble 427 cas, allant du jeu au toilettage et aux soins, dont certains évoquent de véritables liens affectifs...
Une pyramide vieille de plus d'un millénaire s'est effondrée en quelques heures, emportée par des pluies diluviennes. Ce n'est pas un scénario de film catastrophe : c'est la réalité brutale de juillet 2024 au Mexique. Le changement climatique détruit désormais ce que des siècles n'avaient pas...
Une découverte troublante lie la maladie d'Alzheimer à une bactérie présente dans nos bouches. Des chercheurs ont identifié Porphyromonas gingivalis, responsable des maladies gingivales, dans le cerveau de patients atteints d'Alzheimer. Cette piste infectieuse pourrait réformer notre...
McGill University researchers have developed a more energy-efficient method of building AI systems that are better at measuring—and indicating—their own uncertainty. This will help users determine when human oversight is needed, when additional data should be collected and when a model is being asked to work beyond the conditions it was trained for, the researchers said.
32 millions de moustiques lâchés dans la nature, non pas pour piquer, mais pour stopper la propagation de maladies. Le projet de la filiale de Google fait autant parler les scientifiques que le grand public. Une initiative aussi audacieuse que méconnue qui mérite qu'on s'y attarde sérieusement.
L’été 2026 est l’été de tous les records. Derrière ces chiffres, un bilan humain lourd et une menace largement sous-estimée, selon des chercheurs. Celle de températures qui pourraient devenir invivables pour toute une tranche de la population.
99 % des infarctus et des AVC survenus dans une cohorte de plus de neuf millions d'adultes ont été précédés d'au moins un facteur de risque parmi quatre. L'idée d'un accident cardiaque qui frappe sans prévenir en sort ébranlée. Une autre étude nuance toutefois le tableau, en particulier chez les...
Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde compared with Neptune's rotation. The predominant theory is that Triton is a captured Kuiper Belt object that caused a major disruption in Neptune's early moon system. Now, a new study published in Science Advances provides spectroscopic evidence to support this theory.
A recent National Student Safety Survey found that one in six students attending Australian universities had been sexually harassed and one in 20 had been sexually assaulted since starting university.

Scientists are increasingly relying on powerful data sources and tools that they often cannot fully understand, inspect or verify, according to a new study.

Whether on lunch break or on the clock, many employees scroll through the news and social media during the workday. Researchers found that employees who "doomscroll" at work suffer hidden costs that extend beyond lost productivity.
It's 2 a.m., and a teenage girl, worrying about an issue with a friend, lies awake. Rather than wake her parents, she picks up her phone, opens an AI app and types, "I'm so stressed out, I can't sleep."
Fulfilling friendships and close social relationships are strongly linked to excellent physical and mental health, finds a substantial global study published in the Journal of Mental Health.
Kids, marriage and commute: A study co-authored by Dr. Mariana Macedo of Constructor University provides new insights into how major life transitions alter how individuals navigate and experience urban environments. Published in npj Complexity, the research challenges traditional urban planning models that rely on a single, average citizen profile, advocating instead for demographically sensitive city designs.
It doesn't take a scientist to figure out that social media can trend toward the negative. But it might take one to figure out why. In a new paper in PNAS, professor of psychology Joshua Conrad Jackson and colleagues show that algorithms aren't the only driver of online negativity. Another culprit is what psychologists call differentiation, the innate drive to stand out from one's peers.
Alexis Sheffield, a doctoral candidate in clinical psychology, recently published a research article about a study exploring factors that contribute to the elevated rates of sexual assault among bisexual women and to better understand that disparity.
