Why cats prefer silver vine to catnip and other May highlights

fivenewscrypto    juin 03, 2026   

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. May's list includes the discovery of a possible prehistoric mining site in the Pyrenees; a new species of tiny blue octopus; why cats seem to prefer silver vine to catnip; and why political polarization might behave like a phase transition, among other noteworthy stories.

High in the eastern Pyrenees is a prehistoric cave, excavated between 2021 and 2023. Based on analysis of artifacts uncovered at the site, a team of Spanish archaeologists believes this may have served as an ancient copper smelting spot, with far more frequent occupation by humans than previously thought. The researchers described these preliminary findings in a paper published in the journal Frontiers in Environmental Archaeology.

Moderna gets $50 million to develop mRNA Ebola vaccine against Bundibugyo

Moderna gets $50 million to develop mRNA Ebola vaccine against Bundibugyo

fivenewscrypto    juin 02, 2026   

The global health organization Coalition for Epidemic Preparedness Innovations (CEPI) announced Monday that it will "urgently accelerate development" of three vaccine candidates against Bundibugyo ebolavirus (BDBV), pledging a little over $60 million in the effort to extinguish an outbreak currently raging out of control in the Democratic Republic of the Congo.

Under the plans, CEPI has committed up to $50 million to US-based Moderna for preclinical development and Phase 1 clinical testing of its mRNA-based BDBV vaccine candidate. The funding will simultaneously allow the company to ramp up manufacturing capabilities and ready large-scale Phase 2/3 trials in the event the vaccine makes it through early testing. The vaccine will use Moderna's mRNA vaccine platform that allowed for rapid development of a COVID-19 vaccine during the pandemic.

"[W]e believe our mRNA platform can play an important role in responding rapidly to emerging infectious disease threats," Moderna CEO Stéphane Bancel said in a statement Monday. " We will move with urgency and scientific rigor to support the response and help bring a potential vaccine closer to the communities that need it most."

Hackers duped Meta AI support chatbot to steal celebrity Instagram accounts

Hackers duped Meta AI support chatbot to steal celebrity Instagram accounts

fivenewscrypto    juin 02, 2026   

Meta’s AI support chatbot proved unusually helpful to hackers looking to steal and resell notable Instagram accounts—the hackers simply asking the bot to change the accounts’ associated email addresses while using VPN to mask their true locations.

Videos featuring the “shockingly easy” exploit have been circulating among Telegram groups for hackers and security researchers, according to 404 Media. The exploit allowed hackers to take over and flip valuable Instagram accounts worth hundreds of thousands of dollars on the gray market before Meta implemented an emergency patch on May 29. The Barack Obama White House account and the Chief Master Sergeant of Space Force’s account also posted pro-Iranian images and messages while they were temporarily compromised.

Attackers simply had to use a VPN to approximately match their location to the target Instagram account’s region, begin a password reset process, and then ask Meta’s AI support chatbot to change the email address associated with the account, according to 404 Media. It’s a very straightforward prompt injection attack.

New Trump vaccine order based on "no credible scientific evidence," doctors say

New Trump vaccine order based on "no credible scientific evidence," doctors say

fivenewscrypto    juin 02, 2026   

The American Medical Association came out swinging this weekend at an executive order President Trump signed Friday that reaffirms intentions to model US childhood vaccine recommendations after those of Denmark—a country with universal healthcare, less diversity, and a population about the size of Maryland's.

“There is no credible scientific evidence to support," such a change, AMA President Bobby Mukkamala said in a statement. The current vaccine schedule "is built on decades of rigorous research and real-world data, and it is designed to protect children in the US when they are most vulnerable based on our nation’s disease burden," he said.

The plan to align federal childhood vaccine recommendations with Denmark's was first revealed by anti-vaccine Health Secretary Robert F. Kennedy Jr. in January. The overhaul would see the total number of recommended immunizations drop from 17 to 11, walking back recommendations for shots against rotavirus, COVID-19, influenza, meningococcal disease, hepatitis A, and hepatitis B. It stemmed from a December executive order by Trump to align US vaccine recommendations with the "best practices from peer, developed countries."

ROG Xbox Ally X20 adds OLED screen, control upgrades

ROG Xbox Ally X20 adds OLED screen, control upgrades

fivenewscrypto    juin 02, 2026   

When the Steam Deck OLED launched three years ago, we were glad to see that the new, more brilliant screen fixed the biggest flaw of Valve's original handheld hardware. So we're unsurprisingly excited about today's announcement that Asus is preparing a new, OLED-equipped ROG Xbox Ally X20 for the coming holiday season. Still, it's a bit worrying that Asus is positioning the new upgrade as a niche collector's item rather than its new handheld gaming standard.

The X20 expands the 7-inch screen found on last year's ROG Xbox Ally line to 7.4 inches, matching the display on the Steam Deck OLED and approaching the 7.9-inch screen on the Switch 2. The 1080p HDR panel also increases the maximum brightness from 500 nits on original Xbox Ally models to a full 1400 and adds some new anti-glare coating that should help when playing in direct sunlight. The X20's 120 Hz display now supports Dolby Vision HDR colors and FreeSync Premium Pro to help smooth frame rates while still providing a larger color gamut.

On the control front, the X20 introduces magnetic TMR thumbsticks, replacing the carbon-film potentiometers that made the original Xbox Ally more prone to stick drift and physical wear. A new D-pad on the X20 also introduces a neat little lift-and-twist design that can transform it from a four-direction cross to a more circular eight-direction pad, similar to the convertible D-pad found on some now-classic Xbox 360 controllers.

Nvidia RTX Spark comes to Windows PCs with Arm CPU, RTX GPU, and unified memory

Nvidia RTX Spark comes to Windows PCs with Arm CPU, RTX GPU, and unified memory

fivenewscrypto    juin 02, 2026   

These days, Nvidia primarily sells AI data center products, and its traditional consumer devices feel like more of a side project. But the company occasionally still releases something designed for consumers. After a couple of years of rumors, Nvidia has announced an Arm-based chip designed to power Windows PCs. Dubbed RTX Spark, the new chip combines a 20-core Nvidia Grace CPU co-developed with MediaTek, up to 6,144 Blackwell-based GPU cores (the same architecture as the RTX 50-series GPUs), and support for up to 128GB of unified LPDDR5x memory.

Nvidia and its partners offered nothing about expected pricing, but both "slim Windows laptops with all-day battery life and premium displays" and "compact desktop PCs" are slated to be "available this fall" from partners including Asus, Dell, HP, Lenovo, Microsoft, MSI, Acer, and Gigabyte.

This isn't Nvidia's first chip for Windows PCs; earlier chips in the Tegra series powered several of the short-lived Windows RT tablets. But Tegra chips largely stopped appearing in consumer devices following the Tegra X1 in the late 2010s (variants power the original Nintendo Switch and the apparently unkillable Nvidia Shield TV box). Modern Arm-based PCs in the Windows 10 and Windows 11 eras have all used processors from Qualcomm.

Intel: Our upcoming AI chip will be cheaper, run cooler than Nvidia, AMD options

Intel: Our upcoming AI chip will be cheaper, run cooler than Nvidia, AMD options

fivenewscrypto    juin 02, 2026   

Intel plans to ship an AI chip by the end of this year that uses cheaper memory and cooling technology than rival offerings from Nvidia and AMD, as the US chipmaker seeks to capitalize on a sharp turnaround in its fortunes.

Kevork Kechichian, who leads Intel’s data center group, told the FT that the company is “starting with the basics” as it tries to challenge its rivals in the booming market for semiconductors that power AI.

Its new “Crescent Island” graphics processing unit is designed to speed up “inference” tasks, the stage when a user makes their request, rather than the training of models, an area where Nvidia’s processors are dominant.
