A light-activated material now splits water into hydrogen without rare-metal catalysts, pointing to cheaper solar fuels.

The Positive Papers

  1. Citicore Renewables marks 11 years with 1-Gigawatt clean energy milestone
    Citicore Renewables reached one gigawatt of installed clean-energy capacity after eleven years of project development in the Philippines. The company completed multiple solar and wind installations that now feed into the national grid. Capacity at this scale displaces an estimated volume of coal-fired generation each year, though exact displacement figures depend on grid dispatch rules. The milestone shows a private developer can sustain multi-year build-out in an emerging market without repeated government subsidies. One open question is whether similar developers in neighboring countries can replicate the pace when transmission upgrades lag. The result still faces weather and maintenance variability that can reduce realized output below nameplate ratings. The eleven-year timeline reflects steady addition of individual projects rather than a single large installation. Each project contributes to the cumulative one-gigawatt total now operating. Realized annual energy depends on local solar and wind resource quality at each site. Source: manilastandard.net
  2. Scientists just found a new way to make hydrogen from water
    Researchers developed a sulfur-based photocatalyst that produces hydrogen from water under visible light without an added platinum or iridium co-catalyst. Early lab tests show the material maintains activity for multiple hours and avoids the rapid degradation seen in many prior organic photocatalysts. The approach lowers material cost because common sulfur compounds replace scarce metals. Scale-up questions remain around long-term stability under continuous sunlight and the engineering needed to collect the gas at usable pressure. If the chemistry holds, it could reduce the capital cost of decentralized solar-hydrogen systems. The team has not yet published outdoor pilot data. The unusual sulfur-based chemistry is the key feature highlighted by the researchers for future cost reductions. Visible-light operation means the material can use a broader portion of the solar spectrum than some ultraviolet-limited alternatives. No expensive metal co-catalyst requirement removes one major cost driver found in conventional systems. Source: sciencedaily.com
  3. Pomegranates, Walnuts and Berries Could Unlock Heart Failure Treatment By Producing Urolithin A
    King’s College London researchers found that urolithin A, a metabolite formed in the gut after eating pomegranates, walnuts, or certain berries, improved heart-muscle contraction strength by up to 80 percent in models of heart failure with preserved ejection fraction. The compound works by clearing damaged mitochondria inside cardiac cells. Current drug options for this form of heart failure remain limited, so a dietary route to higher urolithin A levels offers a low-cost adjunct. Human trial data are still needed to confirm the magnitude of benefit and the fraction of people who produce the metabolite efficiently. The finding gives individuals a concrete dietary lever while larger studies proceed. The eighty-percent improvement figure comes from controlled models rather than human patients. Mitochondrial clearance is the specific cellular mechanism identified in the work. Limited existing treatments for this heart-failure subtype make the dietary pathway particularly relevant for further investigation. Source: goodnewsnetwork.org

Think Positive

Simon Sinek’s “start with why” principle holds that knowing the deeper purpose behind an action supplies the resilience needed when progress feels slow. When the hosts examine the hydrogen photocatalyst or the urolithin A data, the same pattern appears: the researchers kept refining the work because they anchored it to a clear reason—cheaper clean fuel or better heart-failure options—rather than to any single experiment. Listeners can borrow the same habit. Before beginning today’s chosen action, write one sentence that states the personal “why” behind it; then begin the task. The sentence need not be eloquent; its job is simply to keep the larger reason visible when friction appears. That written sentence acts as a quick reference point during the day whenever motivation dips. The practice turns an abstract goal into a concrete reminder that can be reread in under thirty seconds.


The Lever

Contact your nearest cardiology or nutrition-research clinic this week and ask whether they are recruiting volunteers for any dietary-intervention study on urolithin A or mitochondrial health. The call takes roughly ten minutes and requires only your basic health history. If a study matches, participation may involve blood draws and food logs over several weeks at no cost to you. Early results from related work suggest measurable shifts in cellular energy markers within four to eight weeks for compliant participants. If even one percent of listeners complete the call, clinics gain a larger pool of screened volunteers and accelerate trial enrollment timelines. The main barrier is uncertainty about eligibility; the receptionist can usually clarify that in the first conversation and add your name to a wait-list if nothing fits today. The action stays entirely within one phone call and does not require travel or upfront payment. Clinics listed on university or hospital websites are the practical starting point for locating the right contact number.

Do Positive Dispatch

Yesterday’s lever asked you to request a standard lipid panel blood test from your doctor this month and bring the printed results to your next visit; if you booked the test or received results, reply to the club email with the date you scheduled it and any out-of-pocket cost.


Network pick: Planetterrian Daily (today): “A protein known as the glue holding cells together also helps epithelial cells swallow…”—a cellular-mechanism story that pairs with today’s mitochondrial and dietary findings.
