Over the past week, the laptop Microsoft sent me has been summarizing books and movies, generating images from my imagination, and running a 70-billion-parameter AI model that would be a stretch to fit on most laptops. It also played AAA games at a speed and fidelity I would have thought impossible on an ARM system just a year ago. Microsoft wants to sell you one computer for all of your needs, and for once that doesn't feel like total marketing fluff. Mostly.
Microsoft is throwing both arms around the new Nvidia RTX Spark platform with the Surface Laptop Ultra—and setting its sights on the would-be MacBook Pro buyer, or as the company called it, "a high performance audience." The bet is that rather than a gaming desktop for fun and a development laptop for work, buyers will pay more for one machine that does both.
The Surface Laptop Ultra arrives at a strange time in personal computing. Recent industry numbers showed a 20 percent drop in total PC shipments year over year in the third quarter of 2026. That's not just consumer purchasing either—that's across the board. Between the RAMpocalypse that has exploded consumer prices and an industry fixated on enterprise money, there hasn't been much new hardware to excite PC enthusiasts.
Our leading hypothesis for how our memories are stored is that when you learn something, the connections among neurons involved get stronger and physically larger, and that constitutes the memory. The trouble is that these connections significantly change over time—they’re plastic.
“If you compare the arrangement of these connections on day one with the same on day four or five, it's very, very different," says Kazumasa Tanaka, a neuroscientist at the Okinawa Institute of Science and Technology Graduate University in Japan. To learn how a memory that can last for years can sit on hardware that shifts every few days, Tanaka’s team made the shift a bit more dramatic. In a recent Science study, they induced a hibernation-like state in mice, which basically erased the state of more than half of their synapses. And yet the mice apparently have kept their memories.
Hibernation is a specialty of squirrels, hamsters, and bears, but the neural circuit that triggers it is conserved across mammals, and is present in species that never hibernate in the wild—like mice. In June 2020, a team of researchers led by Takeshi Sakurai, a neuroscientist at the University of Tsukuba and a collaborator on Tanaka’s study, developed a technique to artificially activate this hibernation circuit. This can be done by activating a population called Q neurons in a region of the hypothalamus.
A fruit fly hunting a piece of rotting fruit or a mate navigates by smell, following plumes of odor. Out in the wild, turbulent air swirls these plumes into a chaotic, broken landscape—dense chemical filaments laced through long stretches of clean air. A fly trying to find the source gets the smell in stutters, from constantly shifting directions, with no guarantee that a next whiff is coming at all.
Scientist had little idea of how fruit flies manage this chaotic signal with a brain the size of a pinhead. For a long time, biologists stood by the “surge and cast” model, which posited that insects solved this with hardwired reflexes. The idea was that, when a fly registers the plume with olfactory neurons in its antennae, it simply flies upwind until it’s gone and then flies side to side attempting to catch it again. But now a team led by Vanessa Ruta, a neuroscientist at the Rockefeller University, has shown that fruit flies do something far more advanced.
The trouble with the traditional surge and cast model is that it struggles to explain how an insect tracks a meandering plume across long distances. Chemical cues floating in the air in the natural environment are often sparse and unreliable. But those same features make the mechanism behind olfactory navigation notoriously difficult to test. "Odors are invisible," Ruta says, "and often they're carried along by turbulent airflow." We’ve got no way of knowing what the animal is smelling from one moment to the next.
Apple saw an excellent and better-than-anticipated Q3 2026 in terms of iPhone sales, but its revenue for services—like Apple TV, Apple Music, AppleCare, or iCloud—slipped downward, disappointing experts who were hoping for more. Further, fears about memory prices and supply constraints slightly soured reception to what could have otherwise been a slightly positive but business-as-usual quarter.
That's the key takeaway from the company's Q3 2026 earnings call today.
South Korea’s government and top tech companies are committing $1 trillion to several flagship megaprojects that could bolster global memory chip supply, build new AI data centers, and spur commercial deployment of humanoid robots by 2028.
The announcement comes as South Korean companies such as Samsung and SK Hynix have enjoyed record profits and stock valuations due to the AI industry’s demand for memory chips—with the subsequent supply strain leading to memory chip shortages and higher prices for consumer electronics. Meanwhile, Hyundai Motor Company is racing to mass-manufacture humanoid robots developed by its subsidiary, Boston Dynamics, so that the robotic workers can start taking over certain laborious tasks in automotive factories and other workplaces.
“We must secure the core elements of AI faster than any other country,” said South Korean President Lee Jae Myung in a televised speech on June 29, as reported by BBC News and other media outlets. “Semiconductors, physical AI, and AI data centers are the triple axis for a great leap forward."
A decade ago, AMD added a protection to its high-end CPUs to protect them against cold boot attacks and other types of physical exploits that siphon sensitive data out of the connected memory chips. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to physical attackers.
Over time, AMD added TSME to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips have gotten used to the added security. Recently and without warning or notice, this lower-end line of AMD chips suddenly dropped the protection, and did so in a way that was impossible to detect on Windows machines and required a fair amount of technical work when using Linux.
AMD has yet to say why TSME worked on these CPUs, or even to confirm the change. AMD declined to answer questions sent by email other than to say TSME "is a security feature only applied to PRO CPUs as part of AMD PRO Technologies." The statement is the first known time the chipmaker has explicitly made this restriction public.
