Science Confirms Pricey Audio Cables Offer No Real Benefit

Rigorous measurements by Audio Science Review compared a $4,100 Kimber Kable KS1036 with a $7 Amazon Basics RCA cable, finding virtually identical performance across frequency response, THD+N, and SINAD, and even slightly more interference in the expensive cable; the result supports the view that you don’t need to shell out for pricey cables—the biggest gains come from speakers, amps, DACs, and room treatment rather than cables.

Philly dental clinic shuts down as health officials urge HIV, hepatitis testing

Philadelphia health officials warned patients of Smiles at Rittenhouse Square about potential HIV and hepatitis exposure from April 2025 through May 2026 after an unannounced inspection found unsanitary practices. The clinic is closed and the sole dentist’s license was suspended for public‑health safety concerns. Officials say the risk is likely low, but a list of potentially exposed patients could be hundreds; those seen in the period should get tested, with a hotline (215-685-5488) established and guidance on testing. Hepatitis B vaccination offers protection, but there are no vaccines for HIV or hepatitis C; testing may require multiple blood draws to establish baselines and follow up. A second clinic with a similar name in the same building is not under investigation.

Meta Debuts Forum, a Reddit‑like app built for Facebook Groups

Meta quietly released Forum, a Reddit-like app focused on Facebook Groups that requires a Facebook account and syncs with the main Facebook app. Users can use anonymized usernames, but admins see real identities; the feed surfaces conversations from Groups (potentially across Groups based on interests) and posts cross-post to the main app. It includes AI tools—Ask to pull answers across Groups and an admin assistant for moderators—and is currently in testing with no major public announcement.

Gadgets Don’t Cut Fuel Bills—Performance Upgrades Do

Gadgets Don’t Cut Fuel Bills—Performance Upgrades Do

Project Farm tested fuel-saving gadgets and found they don’t deliver real savings; gains came from performance mods that improve airflow (high-flow exhaust, cold-air intake) plus ECU tuning, and later from driving behavior (lower speeds, proper tire inflation). Baseline 17.06 mpg on a 319k-mile Suburban rose to 18.78 mpg with about $974 in mods, and peaked at 20.39 mpg with driving changes. At ~$4.50/gal, it would take tens of thousands of miles to recoup the investment, meaning the biggest payoffs come from careful driving and proper maintenance rather than gimmicks.

Hantavirus cruise-ship case tests global traveler monitoring strategies

Passengers exposed on the hantavirus-stricken MV Hondius are entering a key window for symptom onset, prompting countries to adopt divergent monitoring—mandatory hospital quarantines in France and Spain vs. voluntary home isolation in the U.S. and U.K.—with varying testing approaches. Incubation averages about three weeks and can extend up to six, leading many nations to monitor for 42 days after disembarkation. The U.S. currently tests only after symptoms appear, a strategy experts warn may miss early infections that timely PCR testing could catch. The case highlights differences in risk communication and public-health resource use as exposed travelers return home and authorities seek to contain spread.

District-by-District Test Scores Echo a Decade of Decline in U.S. Math and Reading

Stanford's Educational Opportunity Project, linked with NAEP, shows third- to eighth-grade math and reading scores have declined over the past decade. The Times provides a district-by-district lookup for changes since 2015, with exclusions for states and districts lacking data (e.g., New York); where 2015 data are missing, baseline scores come from the 2014–2016 average to enable cross-district comparisons.

Indiana Confirms CWD in Franklin County, Expands Regional Surveillance

Indiana DNR confirmed three chronic wasting disease (CWD) cases in wild deer from Franklin, Rush, and Noble counties for the 2025-26 season. The finding expands the state’s CWD Positive Area to LaGrange, Steuben, DeKalb, Noble, Allen, and Whitley counties and triggers enhanced surveillance in Franklin and Rush. Testing is voluntary and free for legally harvested deer, with CDC advising against consuming CWD-positive meat; no human cases have been reported. Hunters can submit samples via DNR head drop sites or participating businesses, while Purdue’s ADDL offers paid testing.

Mass HIV screening urged as Russia battles rising infections

Mass HIV screening urged as Russia battles rising infections

Health Minister Mikhail Murashko urged annual HIV testing for about one-third of Russia’s population to curb rising infections, saying broader screening is essential to reduce transmission. Russia logged roughly 54 million HIV tests in 2024 (about 37% of the population), the highest in years, but WHO data show a high prevalence of about 890 per 100,000 with total living with HIV around 1.25 million in 2025. Officials also note a treatment gap, with about 900,000 officially under medical supervision in 2025. The government frames early detection through expanded testing as the key to preventing further spread.

LAX Automated People Mover Enters Passenger-Free Testing Phase

LAX Automated People Mover Enters Passenger-Free Testing Phase

LAX’s 2.25-mile Automated People Mover begins about 60 days of passenger-free testing with empty trains, running on the planned schedule while officials work through system integration and reliability checks. Before any riders board, the line must operate 24/7 for 30 days without issues; after that, additional testing and user-feedback rounds will follow. The $5.5‑billion project has faced delays since 2019 and ongoing disputes with contractor LINXS, pushing back a public opening, and while officials hope it will be ready for World Cup-related travel, no opening date has been set. The system is designed to ease airport congestion by linking terminals, parking, and pickup/drop-off zones.

Ten Facts Doctors Want Men to Know About Testosterone

Ten Facts Doctors Want Men to Know About Testosterone

Doctors say most age-related drops in testosterone come from ill health and obesity rather than aging itself, with only about 2–3% losing endogenous production due to a medical problem; weight loss and exercise can raise levels, since fat increases estrogen and lowers testosterone. For those with genuine deficiency, testosterone therapy (gel or injections) can improve sexual function, bone density, cholesterol and insulin sensitivity, and may reduce mortality in some conditions, though treatment choice is personal. Beware of self-diagnosis and unregulated private clinics that push therapy, as unnecessary use can suppress natural testosterone and cause infertility. Always confirm with two morning tests, four weeks apart due to diurnal variation; there is no male menopause, and a normal range doesn’t guarantee prevention of age-related decline that might not require therapy.

NASA’s X-59 second test ends early after cockpit warning

NASA’s experimental X-59 supersonic jet ended its second flight after nine minutes due to a cockpit warning, cutting the planned one-hour mission short. NASA said the data collected on systems and handling— aided by a camera-based cockpit display instead of a traditional windscreen—remains valuable as the program pushes toward higher speeds and muffled sonic booms for over-land flights, with more than 100 flights planned to advance the project.
