O MacBook Neo trouxe leveza e um preço competitivo ao ecossistema Apple, mas quem prefere Windows também tem hoje portáteis igualmente leves e capazes para o dia a dia, fáceis de encontrar em Portugal.
The post 4 alternativas leves e compactas ao MacBook Neo sem “esticar” demasiado o orçamento appeared first on Tek Notícias.
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.
“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.
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.
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.

It seems fair to say that Apple's MacBook Neo took the rest of the PC industry by surprise. Companies are used to competing on price and features with $1,000-and-up Apple laptops like the MacBook Air and MacBook Pro, but their $600 and $700 models usually come with cut corners and compromises that are more noticeable than the Neo's. The CEO of Asus admitted to being surprised by the laptop's price (while simultaneously trying to downplay the Neo's value); a Microsoft-backed study comparing PCs to the MacBook Neo included several laptops that can't compete with the Neo's price unless they're deeply discounted.
In the last couple of weeks, we've started to see a more intentional and targeted response to the MacBook Neo from PC makers. These mostly seem to revolve around Intel's low-end Core Series 3 processors, codenamed Wildcat Lake; while Intel's last few generations of low-end chips have mostly been rebrands of older and less power-efficient parts, Wildcat Lake is a new purpose-built budget chip that benefits from Intel's latest CPU and GPU architectures and its 18A manufacturing process. This should help these chips compete better with the Apple A18 Pro in the MacBook Neo.
Many early Wildcat Lake systems have already been announced, though not all have included a price tag, and several have only been announced for the Chinese market as of this writing. Lenovo is planning to launch some IdeaPad Slim models with the new processors, with some optional spec upgrades including 16GB of RAM and a 120 Hz high-refresh-rate display. Asus and HP have also announced some early products.
