Researchers say artificial intelligence system matches human expert classification about 90% of the time

Experts have created an app that uses artificial intelligence to identify dinosaurs from the footprints left behind after they stomped across the land tens of millions of years ago.

“When we find a dinosaur footprint, we try to do the Cinderella thing and find the foot that matches the slipper,” said Prof Steve Brusatte, a co-author of the work, from the University of Edinburgh. “But it’s not so simple, because the shape of a dinosaur footprint depends not only on the shape of the dinosaur’s foot but also the type of sand or mud it was walking through, and the motion of its foot.”

Traditional bodybuilding advice has been to push workouts to the point of failure, and that soreness is an indicator of effectiveness. But recent studies show there’s another way

Until pretty recently, the conventional wisdom about building muscle was that it worked via a system you might think of as “tear and repair” – the idea being that working out causes microtears in the muscle fibres, which trigger the body’s repair processes, encouraging the muscles to come back bigger and stronger.

That’s why many old-school trainers will tell you that there’s no gain without pain, and why a lot of bodybuilding advice includes increasingly byzantine ways of pushing your biceps and triceps to the point where you can’t do another repetition: the more trauma you can cause, the thinking goes, the more “swole” you can become.

Researchers observed the primates switching social groups and passing information on where to find the ripest fruit

Spider monkeys share tips about where to find food by changing their social groups in a “clever system for sharing insider knowledge”, research has shown.

They were observed to frequently switch subgroups of three or more individuals in a way that enabled them to share information about the location of fruit trees and timing of when they would ripen.

Why do some people age better than others? Five extraordinary individuals – who scientists are studying – share their tips

Lajuana Weathers is determined to be the healthiest version of herself. She starts each day with a celery juice, is always trying to increase her step count, and meditates daily. Weathers is also 89 years old. And she has no plans to slow down. “I wake up in the morning and feel blessed that I have another chance at a day of life,” says the grandmother of six, and great‑grandmother of six more, who lives in Illinois in an independent living facility for seniors. “I look at my life as a holistic entity, and in that life is my physical, social, emotional and spiritual wellbeing. I have to take care of all of those. That’s what I like about the ageing process. All the clutter of raising children is out and I can concentrate on the wellness of me.”

Weathers is a superager. This isn’t a self-proclaimed label, but one backed up by science – she is part of the SuperAging Research Initiative at the University of Chicago. To qualify for the study, you have to be over 80 years old and have memory performance that’s at least as good as the average 50- to 60-year-old. There are about 400 superagers enrolled across North America.

Les hommes seraient plus épargnés par le temps que les femmes, et leur horloge biologique serait moins importante que celle des femmes lorsqu'il est question de parentalité. Si ce n'est pas entièrement faux, ce n'est pas 100 % vrai non plus : on vous explique pourquoi.

Selon les projections des géologues, la planète Terre n'aura plus rien à voir avec ce que l'on connaît aujourd'hui dans 250 millions d'années. Si la France existe toujours d'ici là, elle occupera une place de choix sur le planisphère.
