Fruit Fly Gyroscopes: Unveiling the Internal Architecture of Flight Stabilizers

Spanish researchers have discovered that the fruit fly's haltere, a gyroscopic organ essential for flight stability, is not hollow. Its unique shape arises from an intricate internal cellular structure acting like architectural supports. These structures connect via cellular projections and a protein matrix (laminin and collagen), creating an internal tension system that counteracts external forces and maintains the haltere's shape. Experiments with genetically modified fruit flies showed that disrupting this system leads to haltere deformation and impaired flight stability. This research not only reveals the developmental mechanism of the fruit fly haltere but also offers new insights for tissue engineering and biomimetic structure design.

US Electricity Prices Soar: Wholesale Costs and Transmission Bottlenecks

Since 2020, US electricity prices have skyrocketed by 35%. This article delves into trends in wholesale electricity prices, finding that the increase is linked to both generation costs and transmission bottlenecks. Independent System Operators (ISOs)/Regional Transmission Organizations (RTOs) manage electricity markets using Location Marginal Pricing (LMP), composed of energy, congestion, and losses. Analyzing LMP data across various ISOs/RTOs reveals a significant surge in wholesale electricity prices since 2020, partly due to rising natural gas prices. However, transmission bottlenecks are increasingly significant, hindering the movement of inexpensive electricity from low-cost areas to high-demand regions, amplifying price volatility. California's solar power growth and natural gas supply shortages in certain areas exacerbate transmission congestion.

Can America Still Build Stuff? The Data Says Yes

This data-driven article refutes the claim that America has lost its ability to build large-scale projects. Using numerous charts and graphs, the author demonstrates continued growth in US construction across housing, roads, utility-scale solar plants, pipelines, and bridges. While acknowledging that regulations like environmental protection laws may cause some delays, the article argues their benefits outweigh the costs. The author contends that the focus on failed projects overshadows the numerous successful ones, suggesting that reduced large-scale construction often results from project completion rather than a decline in capacity. Examples such as high-speed rail projects illustrate this point.

Cisco Firewall and TLS 1.3 Compatibility Issues

2025-05-22

A company encountered a problem with their Cisco firewall: due to TLS 1.3 encrypting server certificates, the firewall couldn't enforce URL or application access rules based on certificate content. To solve this, Cisco introduced TLS Server Identity Discovery, using an additional TLS 1.2 handshake to retrieve the certificate in plaintext. However, this clashed with expected Postgres database behavior. The actual issue wasn't TLS 1.3 incompatibility, but rather the firewall wasn't configured to block unknown applications; it attempted to learn the certificate for 3 seconds before giving up and allowing the connection.
