Gut Microbes Transform Veggie Nitrates and Iron into Molecules Potentially Boosting Heart Health

Karolinska Institutet researchers found gut bacteria convert dietary nitrate and nonheme iron from vegetables into dinitrosyl iron complexes (DNICs), which circulate to tissues and may support cardiovascular and metabolic health. DNICs were absent in germ-free mice, confirming a microbiome role. In animal models, boosting DNIC levels improved blood pressure, vascular function, glucose control, and reduced liver fat, suggesting a mechanism by which vegetables may reduce disease risk, though human relevance and measurement methods require further study.

Clocking Your Supplements: What the Science Really Says About Timing

A review of 84 studies finds that for generally healthy adults routine vitamin and mineral supplements offer little protection against heart disease, cancer, or early death and may cause harm when taken without a clear need. When timing matters, it’s about absorption rather than the clock: iron absorption can be sharply reduced by coffee and large calcium-rich meals (with a vitamin C boost helping modestly), while vitamin D is better absorbed with fat-containing meals. B12 timing is less crucial unless absorption is impaired by factors like metformin or acid suppressants. In most cases, follow product instructions, consider addressing definite deficiencies, and consult a clinician before adding supplements, especially if you’re on other medications or taking high doses.

Five brain-boosting nutrients and their best food sources, per neurologist Dr. Rahul Chawla

Neurologist Dr. Rahul Chawla highlights five nutrients essential for brain function—Vitamin B12, Omega-3 fatty acids (DHA), iron, folic acid, and flavonoid antioxidants—along with their key food sources (meat/fish/dairy, flax/chia/walnuts, lentils/beans/spinach, leafy greens/citrus, berries/dark chocolate), and notes that correcting deficiencies and ensuring adequate protein, choline and magnesium support overall brain health.

Supplements under the microscope: when pills help and when to skip

Most people gain little from supplements if they eat well; multivitamins show only tiny memory benefits, and real food is the best source of nutrients. Some supplements may help in specific cases—creatine for athletes, collagen for certain skin/joint needs, vitamin D in UK winters, magnesium for those with low intake, omega-3 for non-fish eaters, and iron for deficiency—though these should be guided by a clinician. Focus on a balanced plate with protein, a variety of plants, fiber-rich carbs and healthy fats, and use supplements only where clearly indicated.

Sip Smart: How Coffee Can Affect Your Supplement Absorption

Coffee can interfere with the absorption of iron, calcium, vitamin D, B vitamins, zinc, and magnesium. To maximize uptake, time your coffee 1-2 hours away from taking supplements or eating vitamin-rich foods, and consult a healthcare professional before starting any supplement regimen.

Psyche: a metal-rich asteroid reshaping planetary science

Asteroid 16 Psyche, about 225 km wide in the main belt, may contain large amounts of iron and nickel, prompting a back‑of‑the‑envelope figure of around $10 quintillion that is more a scale marker than a mining forecast. NASA’s Psyche mission (launched 2023) will map its composition and structure to understand whether it’s a remnant planetary core or a mixed rock-metal body, shedding light on planetary formation rather than turning Psyche into a market resource.

Smart Food Pairings to Boost Your Nutrient Uptake

Dietitians say you can boost nutrient absorption by smart pairings: combine vitamin C–rich foods with iron-rich plant foods (e.g., strawberries in a spinach salad or a lemon-dressed lentil salad); add healthy fats to meals containing vitamins A, D, E and K (olive oil on salads, seeds/nuts); use spices like black pepper, garlic, and ginger to improve zinc, iron, and curcumin absorption; pair vitamin D sources with calcium (fatty fish with leafy greens) to enhance calcium uptake; and focus on a varied, nutrient-dense diet to maximize the bioavailability of nutrients.

Cape Cod meteor likely iron with unusual density, NASA finds

NASA says the Cape Cod Bay meteor was likely an iron meteorite, unusually dense at about 8,000 kg/m³, broke apart around 31 miles up with few small fragments, and could potentially be recovered from the ocean floor; the density estimate is preliminary and awaits further analysis.

Experts warn against common supplement pairings that can block absorption

A TODAY health explainer warns that popular supplements can interfere with each other at high doses, reducing absorption or causing unintended effects. Notable combinations to avoid include calcium with iron, calcium with magnesium, calcium with zinc, zinc with copper, zinc with iron, and vitamin C with vitamin B12 or high-dose vitamin E with vitamin K. Experts advise taking interacting nutrients several hours apart, consulting a doctor, verifying supplement quality, using third-party certifications, and prioritizing a food-first approach rather than megadosing to replace a healthy diet.

Iron-Forged Fossils Unveil a Lost Australian Rainforest

In New South Wales, researchers uncover exceptionally preserved fossils embedded in ferricrete goethite, revealing a Miocene rainforest with fine details like feathers and insect organs and showing iron minerals can preserve soft tissues, potentially guiding future searches for iron-based fossil deposits worldwide.

Iron and UV light unlock cheap hydrogen from alcohols

Scientists at Kyushu University discovered that mixing methanol with iron ions and sodium hydroxide and then exposing the mixture to UV light triggers a rapid release of hydrogen—921 mmol per hour per gram of catalyst—comparable to costly modern catalysts. The approach works with other alcohols and biomass feeds, offering a cheap, abundant iron-based route to sustainable hydrogen production. Although the reaction mechanism isn’t fully understood yet, the simple setup could be replicated widely and help decouple hydrogen generation from fossil fuels; researchers plan to optimize the process moving forward.

Antarctic Earthquakes Trigger Rapid Surface Phytoplankton Blooms

New research links underwater earthquakes near the Australian Antarctic Ridge to boosted surface phytoplankton blooms by enhancing iron release from hydrothermal vents, speeding nutrient delivery to the surface and cascading through the Southern Ocean food web, with potential implications for ocean carbon uptake and climate models. The study combines decades of satellite data with seismic records and points to a surprising, faster-than-expected pathway from deep-sea fluids to surface life.

League Ranked Rebalance Targets Fairer Climbing: Iron for Learners, Master Expansion

Riot explains changes to ranked MMR distribution to improve fairness and competitiveness: Iron becomes a true learning tier by pulling more experienced players into Bronze, while the upper end of Diamond is moved toward Master to reflect playing levels; ongoing and future tweaks include possible Apex-tier expansion, LP dynamics improvements in Master+, and autofill/secondary-role parity tests with planned rollouts in 26.4 and 26.5.

Antarctic melt releases iron that may stall the ocean's carbon sink

New findings show iron released from melting West Antarctic ice is chemically altered and not usable by marine algae, potentially reducing the ocean’s capacity to absorb carbon dioxide. If ice loss continues, less algae could form, diminishing carbon uptake and possibly accelerating warming and sea-level rise.

Ancient Vietnamese teeth dyed black: iron-based paste reveals 2,000-year-old beauty trend

Archaeologists studying 2,000-year-old skulls from Vietnam’s Dong Xa Iron Age site found iron oxide and sulfur in tooth enamel, indicating ancient people dyed their teeth black with an iron–tannin paste—likely using tannins from betel nut. The practice, dating to the Iron Age, was a cosmetic trend that persisted in parts of Southeast Asia and would have required days to weeks of application with periodic touch-ups.
