The study of Indonesian kids shows that being short (stunted) doesn’t always mean a child is malnourished; many short kids had normal body fat and no signs of illness, while overweight kids grew taller. This challenges the idea that low height automatically signals poor nutrition.

A small study looked at four teenage girls who have a rare genetic change (SHANK3 mutation) that caused a sudden drop in mental health, like mutism and hallucinations. Traditional meds didn’t help much, but treatments that calm the immune system seemed to improve their symptoms, and two girls got back to their normal level of function.

In a study of Mexican‑American adults, the researchers found that having unhealthy blood pressure, cholesterol, blood sugar, insulin resistance, or inflammation was linked to early signs of artery thickening, while simply being overweight or obese didn’t add extra risk. People who weren’t obese but had these metabolic problems showed the same artery changes as obese people. This means keeping your metabolism healthy matters more than just losing weight.

The study shows that the natural hormone α‑melanocyte‑stimulating hormone (α‑MSH) can calm down basophils, a type of immune cell involved in allergies, by binding to the MC‑1R receptor and lowering allergy‑related signals. However, the short peptide KPV, which some biohackers experiment with, did NOT have any effect on basophil activity or cytokine release.

In mouse models of lung cancer, the protein vimentin is essential for tumors to grow quickly and spread. Mice that lack vimentin or are treated with a compound called withaferin A develop smaller tumors and live longer. Without vimentin, cancer cells become more vulnerable to a type of cell death called ferroptosis.

In rats that suffered severe burns, the amount of aldosterone that could bind to kidney cells dropped, which could affect fluid balance and blood pressure. Giving the anti‑inflammatory peptide KPV (Ac‑D‑Lys‑L‑Pro‑D‑Val) helped keep the aldosterone binding levels normal, similar to other anti‑inflammatory agents like anti‑TNF antibodies and alpha‑MSH.

A big analysis of five randomized trials looked at whether putting drug‑coated stents (PCI) is as safe and effective as heart bypass surgery (CABG) for a serious blockage in the main heart artery. It found that both methods are equally safe in terms of death, heart attacks, and strokes, but stents lead to more repeat procedures later on.

The tiny peptide KPV can block inflammation signals in lung cells by stopping a key protein (p65RelA) from entering the nucleus. It works in a dose‑dependent way and reduces inflammatory chemicals like IL‑8 and eotaxin. A related hormone, γ‑MSH, does something similar but through a specific lung receptor (MC3R).

Alpha-MSH and its short piece KPV can calm down inflammation by stopping a key switch (NF‑kB) that turns on inflammatory genes. They work both in the body and in the brain, and cells that make more of this peptide become resistant to bacterial toxins.

People who carry certain rare truncating mutations in the heart protein titin (TTNtv) generally have a normal lifespan, but after age 60 they face a modestly higher risk of death, especially in recent decades. The extra risk is small (about 10‑30% higher) and appears mainly in older adults.

Researchers found that a tiny piece of the hormone alpha‑MSH, called KPV, can lower HIV virus activity in lab-grown immune cells. The peptide seems to work by blocking a cell signal (NF‑kappaB) that the virus uses to replicate. While the effect is clear in test tubes, there’s no data yet on safety or effectiveness in people.

Scientists built tiny particles that carry the anti‑inflammatory peptide KPV and hide them inside a special gel that only breaks down in the colon. In mice with chemically‑induced colitis, this system released the peptide right where the gut is inflamed and dramatically cut down inflammation, even though the amount of KPV used was 12,000 times lower than if you just gave the free peptide.

Researchers found that a special type of MRI scan can accurately estimate how well each kidney works in kids with swollen kidneys, matching the results of the usual radioactive scan. This means doctors could use MRI instead of the more invasive test.

A review says the body’s melanocortin system can calm gut inflammation in mouse models of IBD, and drugs that tweak this system might someday help treat Crohn’s or ulcerative colitis, but there’s no ready‑to‑use supplement or protocol for people now.

The study shows that a lung‑cancer drug called amivantamab works best in tumors that have high levels of a protein called amphiregulin (AREG). This effect is seen even without the immune system’s help, suggesting the drug blocks the protein’s signal directly. While interesting for cancer treatment, it doesn’t give any direct tips for everyday health or longevity practices.

Researchers found that babies with a rare genetic disease called Aicardi‑Goutières syndrome (AGS) often show higher levels of a lipid marker (C26:0 Lyso‑PC) and an interferon‑related gene signature in newborn blood spots, which could cause them to be flagged as positive in newborn tests meant for a different disease (X‑linked adrenoleukodystrophy).

A study gave hydrocortisone to very premature babies to see if it would help them survive without lung disease or brain problems. The drug didn’t meaningfully improve survival or reduce lung issues, and it didn’t change brain outcomes either, but it did raise the chance of high blood pressure. For most people, especially those looking to boost health or performance, this isn’t a useful or relevant finding.

A big study gave newborns with brain‑oxygen loss a drug called erythropoietin, hoping it would protect their brains, but it didn’t lower death or disability and actually caused more serious side effects.

The study shows that a MRI‑based measure called the gadoxetic acid uptake rate (k1) combined with liver size (k1VL) lines up well with traditional liver function tests, while the portal‑vein perfusion rate (kpv) does not. This imaging trick helps doctors see how well different parts of the liver are working, especially in sick livers, but it isn’t something you can use at home.

The study found that a protein called NLRP3 builds up in skin cells (melanocytes) of people with vitiligo because a helper protein (β‑TrCP1) is missing, which stops the cell’s cleanup system (autophagy) from removing NLRP3. This buildup triggers inflammation and cell death, worsening the skin spots. Researchers packaged a gene‑silencing tool (shRNA) inside tiny KPV‑coated liposomes that specifically target melanocytes and knock down NLRP3, which reduced vitiligo signs in mice.
