Voici pourquoi laisser un fruit abîmé dans son jardin serait un geste précieux pour la biodiversité

30 July 2026 at 17:00
Une pomme fripée, une poire trop mûre, abandonnées au fond du jardin par simple négligence. Ce geste anodin peut pourtant sauver la mise à tout un cortège de créatures affamées. À l'approche de l'hiver, un fruit oublié devient un festin vital. Et un coup de pouce insoupçonné à la biodiversité.

Apple’s eras keep changing, and so do mine (Macworld/Jason Snell)

25 June 2026 at 12:00

My first day on the job at Macworld, Apple was perilously close to going out of business. It was the fall of 1997, and Steve Jobs had returned to Apple and engineered the ejection of Gil Amelio as CEO, but there was no iMac yet, no visible turnaround in terms of products at all. Beyond the release of the iconic “Think Different” ad campaign, there was nothing.

Apple’s survival hung by a thread. Steve Jobs asked everyone to trust him. At Macworld Expo, he had enlisted Bill Gates—Bill Gates, of all people!—to help him instill belief in the world that Apple would find a way to survive.

The world was skeptical, to say the least. My family asked what job I thought I’d get once Apple went out of business. The magazine I had worked at for four years, MacUser, had been folded, and some of us had been transferred over to our rival, Macworld, presumably to publish issues until Apple finally gave up the ghost and died. We existed to minimize the loss exposure of our respective publishing companies.

1997 was weird, folks. And that’s how my tenure at Macworld started.

Apple’s 27 OS releases are out of the ordinary–in a good way (Macworld/Jason Snell)

A few bug fixes and improvements for this year.

The last two years at WWDC, Apple has felt like it’s been in a hurry. In 2024, in a hurry to catch the AI wave before it entirely passed them by. (They didn’t catch that wave—they wiped out, lost their surfboard, and may have been partially gnawed on by a shark.) Then last year it felt like it was trying to cover up its embarrassment about AI failures by rushing out a new design scheme that felt ill conceived, especially when it came to the Mac.

This year feels different. Apple is unveiling a second take on its AI plans, but it feels like they’ve spent the intervening two years trying to make sure that this time, it sticks. And when it comes to almost every other announcement at WWDC 2026, it feels like the company is taking stock, measuring twice, and cutting once. As famed basketball coach John Wooden warned his young charges, it’s important to be quick—but not to hurry.

12 semaines de jeûne intermittent : une étude révèle ce qu’il reste de la perte de poids un an après

Perdre du poids est une chose, éviter de le reprendre en est une autre. Selon une étude publiée dans Clinical Nutrition, le jeûne intermittent pourrait contribuer à maintenir les résultats obtenus plusieurs mois après la fin de l'intervention. Que faut-il réellement en penser ?

Deep in the Jungles of Borneo, Scientists Just Discovered a “Hyperparasite” Organism That Preys on Zombie Fungi

22 June 2026 at 15:28

Scientists working in the jungles of Borneo report an unsettling discovery: a parasitic organism that they say has a hunger for zombie fungi.

This “hyperparasite” fungus thrives, according to Malaysian scientists behind the discovery, by feeding on forms of fungi that are known to infect insects and temporarily take control of them before ultimately killing them.

The unusual fungus was discovered during field trips by researchers with the University of Malaysia Sabah’s Institute for Tropical Biology and Conservation, who have designated it a hyperparasite because of its unique strategy of feeding through parasitizing another parasite organism.

A Hyperparasitic Zombie-Killer

“The fungus belongs to the genus Pleurocordyceps and acts as a specialized hyperparasite,” said Jaya Seelan Sathiya Seelan, the institute’s deputy director, in a statement provided to AFP last week.

In the television show and related video game series, The Last of Us, a unique approach to the idea of a zombie apocalypse is presented, where humans can become infected by a novel variety of cordyceps. Fortunately, in real life, these parasitic fungi only manipulate insects by hijacking their nervous systems and temporarily taking control of their bodies for a time.

The infected insects begin engaging in erratic behavior as the parasitic fungus takes hold, which eventually fills their bodies and then bursts out in a final, gruesome death for the unlucky host.

A Horned Hyperparasite

The newly discovered “hyperparasite,” Pleurocordyceps cornusynnemata, garners its name from a distinctive horn-shaped appearance, and works by targeting insects—namely tropical ants—which have already been infected by a variety of zombie fungus known as Ophiocordyceps.

“Rather than manipulating the insect’s nervous system itself, Pleurocordyceps infiltrates and feeds directly on the thriving Ophiocordyceps tissue inside the host,” Seelan recently explained, adding that the unique fungus was discovered while investigating a dead ant specimen that was collected from the Danum Valley in southern Sabah.

Although Pleurocordyceps cornusynnemata is not the first hyperparasite fungus known to science, Seelan said it is the first recognized by science possessing its distinctive horn-shaped structure.

The research team with the University of Malaysia Sabah’s Institute for Tropical Biology and Conservation also says they discovered a new species of fungus that similarly attacks and kills spiders by spreading its invasive spores throughout their bodies before death.

Parasites with Promising Potential

Despite their unsettling parasitic nature, scientists are very intrigued by cordyceps. One reason is that these fungi that can hijack and “zombify” the nervous systems of some insects also possess a range of health benefits when consumed by humans, which include boosting energy and athletic stamina, as well as supporting immune function and helping to reduce inflammation.

“These newly documented fungi hold immense potential,” Seelan told AFP, “both as sources for developing next-generation antimicrobial drugs and as highly effective biocontrol agents against agricultural pests.”

The team’s findings were published in a recent study, titled “Taxonomy and phylogeny of Pleurocordyceps (Polycephalomycetaceae, Hypocreales) associated with ants and cicadas from Malaysia, including a new species and new records,” which appeared in the journal Phytotaxa.
