Cosmic Void: Are We Living in a Giant Void?

New research suggests we might reside within a vast cosmic void, potentially resolving the 'Hubble tension'—the discrepancy in the universe's expansion rate. Analyzing the 'sound' of the early universe (baryon acoustic oscillations), researchers found our local region has roughly 20% lower matter density than average. This low-density void would gravitationally affect observations, making the universe appear to expand faster, aligning with measurements. The study concludes that a universe model incorporating a local void is significantly more likely than one without, offering a novel perspective on a long-standing cosmological puzzle.

Game Changer: First 100% Protective HIV Drug Approved

A 44-year battle against HIV may finally be turning the corner. The FDA has approved lenacapavir (Yeztugo), a twice-yearly injection offering nearly 100% protection against HIV infection. This capsid inhibitor prevents viral replication, marking a monumental breakthrough. Gilead Sciences is ensuring global access by offering affordable pricing and signing royalty-free licensing agreements with six generic manufacturers. This innovative approach, combined with partnerships like the one with the Global Fund to fight AIDS, aims to reach up to two million people in low- and lower-middle-income countries, signaling a potential turning point in the fight against the HIV epidemic.

Volt Boot: Exploiting Power Domain Isolation to Bypass On-Chip SRAM Security

2025-07-29

This paper introduces Volt Boot, a novel attack that leverages power domain isolation in modern Systems-on-a-Chip (SoCs) to compromise the security of sensitive information stored in on-chip SRAM. Traditional cold boot attacks are ineffective against on-chip SRAM, but Volt Boot achieves cross-power-cycle SRAM data retention by maintaining the voltage of the target memory domain during system reset. Experiments on three commercially available Cortex-A processors successfully extracted data from caches, CPU registers, and iRAM, demonstrating the attack's effectiveness. The research highlights new security challenges for systems relying on on-chip computation and proposes countermeasures such as eliminating power domain isolation, purging residual memory, resetting SRAM at startup, and enforcing TrustZone support.

Robot Hand Outperforms Humans at Blackberry Harvesting

Researchers at the University of Arkansas have developed a novel soft robotic gripper capable of harvesting blackberries more efficiently than humans. Inspired by the opening and closing of a tulip, the gripper features three soft fingers and force sensors to ensure gentle handling and prevent damage. By measuring the force used by human pickers, researchers optimized the gripper's picking parameters. While further development of computer vision and positioning technologies is needed, the gripper demonstrates potential to surpass human capabilities in efficiency and consistency, promising applications in other soft fruit harvesting and assistive technologies for people with limited mobility.

Is DJI Circumventing US Bans with the SkyRover X1 Clone?

With an unofficial US customs ban in place, DJI drones are practically unavailable in the US. Yet, a near-identical clone, the SkyRover X1, is readily available on Amazon. Investigations reveal striking similarities: identical specs, features, app, and even use of DJI's online infrastructure. Security researchers have even logged in using their DJI credentials. While the manufacturer denies a DJI connection, evidence suggests DJI's involvement, possibly through licensing or other means, mirroring past strategies using third-party manufacturers. Although not officially banned, a de facto ban looms, forcing DJI to employ creative methods to maintain market presence.

Algospeak: How Social Media Is Reshaping Language

Adam Aleksic's new book, *Algospeak*, explores how social media algorithms are transforming language. Algorithms fuel the creation and spread of new words, slang, and grammatical rules, like "rizz," "aura," and "-pilled." While the author views this "algospeak" as showcasing human adaptability and ingenuity, he also highlights potential downsides, including power imbalances and cultural homogenization – such as the mainstreaming of online subculture slang and appropriation of African American Vernacular English (AAVE). The review also touches on the algorithm's impact on the attention economy and culture, and the potential negative consequences for reading and literature.

Black Holes, Satellite Navigation, and a Crowded Radio Highway

Global satellite navigation systems rely on precise measurements of Earth's position, which in turn depends on observations of black holes at the centers of distant galaxies. Scientists use radio telescopes to receive radio waves from black holes, but in recent years, electromagnetic pollution from WiFi, mobile phones, and satellite internet has become increasingly severe, crowding the radio spectrum and interfering with observations of black hole signals. This threatens satellite navigation and many other services that rely on precise Earth positioning. Solving this problem requires international cooperation, securing more radio spectrum resources for geodesy at World Radio Conferences, or establishing radio quiet zones around essential radio telescopes.

Beetroot Juice, Oral Microbiome, and Blood Pressure in Older Adults

A new study reveals that the blood pressure-lowering effect of nitrate-rich beetroot juice in older adults may be linked to specific changes in their oral microbiome. Researchers found that after two weeks of consuming concentrated beetroot juice twice daily, older adults experienced a decrease in blood pressure, unlike younger participants. This effect is likely due to the suppression of potentially harmful oral bacteria, impacting the conversion of nitrate to nitric oxide, crucial for vascular health. The study suggests that encouraging older adults to consume more nitrate-rich vegetables could offer significant long-term health benefits.

Ancient Japanese Culinary Traditions Outlasted the Rice Revolution

New research reveals that the introduction of rice farming to Japan 3,000 years ago, while transformative, didn't immediately overhaul Japanese cuisine. Despite the simultaneous arrival of millet, a staple in Korean cooking, analysis of pottery residues and plant remains shows it failed to gain traction in Japanese diets. Fish remained a primary food source, highlighting the resilience of culinary traditions in the face of significant technological shifts. This suggests that cultural practices can persist even with major agricultural changes.
