Things Worth Noting
Physics is full of unsolved mysteries that baffle scientists. Dark matter (27% of the universe) and dark energy (68%) drive galaxies apart and speed up expansion, yet remain undetected. The cosmic microwave background supports inflation, but why the universe began so uniform is unknown. Matter dominates over antimatter due to baryon asymmetry, and the arrow […]
Humanity faces existential risks that could end our future, from natural disasters like asteroid impacts, supervolcanic eruptions, gamma-ray bursts, and solar flares to human-made threats including climate change, nuclear war, pandemics, superintelligent AI, and cyberattacks. Climate drives biodiversity loss and societal collapse through extreme weather and resource scarcity. Nuclear winter from war could kill billions […]

In an era of economic uncertainty, with inflation stabilizing but fiscal pressures mounting, building wealth from nothing remains a realistic pursuit for those committed to discipline, patience, and strategic action. Whether you’re starting with zero savings or burdened by debt, the path to financial independence involves cultivating a growth mindset, setting clear financial goals, and […]
On November 11, 2025, a powerful X5.1 solar flare erupted from sunspot AR4274 during solar cycle 25’s peak, causing R3-level radio blackouts across Africa and Europe. The flare’s soft X-rays ionized the ionosphere, disrupting high-frequency (HF) radio used in aviation, maritime, and emergency services, while also causing GPS errors and radar interference. A coronal mass […]
Vitamin D3 supplementation may cut the risk of a second heart attack by 50% in survivors, according to the TARGET-D trial. This study of 630 recent heart attack patients used targeted dosing to raise blood levels above 40 ng/mL, often requiring 5,000 IU or more daily. While overall major cardiac events showed no big change, […]
U.S. shoppers are outraged as steep tariffs threaten Italian pasta imports. The administration imposed a 15% baseline tariff on EU goods, plus up to 91.74% anti-dumping duties, totaling 107% for brands like Barilla, La Molisana, and Rummo. A Commerce Department probe found Italian firms dumping pasta below fair value, harming U.S. producers. Duties start in […]
Kefir and yogurt are both fermented dairy foods packed with probiotics for gut health, but they differ in ways that matter. Yogurt uses two main bacteria (Lactobacillus bulgaricus, Streptococcus thermophilus) and has a thick, creamy texture. Kefir ferments with kefir grains—a mix of up to 61 bacteria and yeasts—making it fizzy, drinkable, and more probiotic-diverse. […]
The cornea heals fastest—scratches often clear in 24-48 hours thanks to quick cell growth and eye lubrication. The mouth follows closely; tongue or cheek cuts mend in days, three times faster than skin, due to moist saliva, helpful bacteria, and active genes like SOX2 that speed repair with less scarring. Muscles and tendons heal well […]
Saving money won’t make you rich—inflation erodes its value, and low returns in savings accounts or high-yield options fail to beat rising costs. Over time, your nest egg loses real purchasing power. Instead, invest in the stock market, where historical S&P 500 returns average 10% annually through compound interest and capital gains. Diversify with index […]
