Phages explode bacteria to share vital vitamin B12 with microbes

Vitamin B12 is biological gold. All living organisms need a little bit of it to form red blood cells and DNA, as well as to build and support brain and nerve cells.

Genetic changes in zebrafish reveal new pathways for back pain

Neck and back pain could be caused by changes in gene activity that trigger the breakdown of the spine's natural shock absorbers, new research suggests.

First-trimester protein intake linked to lower odds of small-for-gestational-age birth

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

Blood filtration method helps clear circulating lipids and toxic microplastics

The machine is not new. Some version of it has run in hospital treatment rooms for about four decades, drawing blood from one arm, separating out the plasma, passing it across a filter or an adsorber, and returning it to the other arm.

Complete medaka genome sequence reveals repetitive DNA with biological significance

Researchers sequenced the genomes of three medakas, or Japanese rice fish, which are a common model organism used for biological research, nearly 10 and 20 years ago.

Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

Researchers uncover hierarchical sensory processing system in the zebrafish brain

How does the brain make sense of what we see, hear, and feel—and transform these separate signals into a coherent perception of the world?

Perilla oil improves blood flow and reduces inflammation in healthy smokers

Cardiovascular disease (CVD) is among the leading causes of death worldwide. In South Korea, it is the second leading cause of death, and its incidence has continued to rise in recent years.

New light-sheet imaging system tracks brain seizure dynamics in 3D

Seizures can race through the brain in seconds, making them difficult to capture in detail. To overcome this challenge, researchers have developed a new high-resolution light-sheet imaging system that is fast enough to image seizure propagation in the brain of a larval zebrafish in 3D.

Fish oil supplementation during pregnancy changes two childhood brain metabolic markers

Randomized maternal fish oil supplementation from pregnancy week 24 lowered offspring cerebral blood flow and oxygen metabolism at age 10 but did not alter precuneus lactate. The small differences resembled a more adult-like metabolic profile, although researchers found no associated cognitive or behavioral benefits.

New project documents vanishing heritage diets for future health benefits

The world's 'heritage' diets could hold vital clues to better health. Writing in Nature Medicine, researchers from 12 countries have launched the World Diet Initiative, a global effort to document and study these diets before this knowledge is lost.

Blue LED lights help chemists build complex drug molecules

In drug discovery, building complex molecules quickly is the name of the game.

Lung tumors hack the nervous system to cause severe cachexia

Cachexia is a condition in which patients affected by cancer or other chronic diseases become sick and lose weight.

New Italian data show extreme longevity is spreading beyond the blue zones

A nationwide ecological analysis of Italian regions found that aging and extreme longevity indicators rose steadily from 1982 to 2025, with northern and central regions generally leading. Regional patterns linked higher longevity indices to lower diabetes and cerebrovascular mortality and healthier contemporary nutrition profiles, while Cilento emerged as a notable southern hotspot.

Meat and dairy cuts may improve health without raising food costs

A Scottish microsimulation study found that reducing meat and dairy intake, especially red meat among high consumers, could improve modeled health and environmental outcomes without increasing diet costs. However, some nutrient intakes, particularly calcium and iodine, declined, highlighting the need for carefully planned substitutions and fortified alternatives.

New fluidic technology makes soft robots and wearables three times more powerful

Researchers have found an ingenious way to make soft robots and wearable technology more than three times more powerful by harnessing the surface tension of a tiny liquid metal droplet smaller than a rain droplet.

Dutch study shows why plant-based eating can miss key nutrients

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.

New labeling scheme could reduce Listeria infections from ready-to-eat foods

Listeria infections are on the rise, and around 15% of people in the EU who contract the infection die from it.

Fish-inspired device enables scalable monitoring of beating heart organoids

An international team, including the University of Tokyo, has created a sensor inspired by the lateral line in fish - their "sixth sense" organ - which measures the pulse of lab-grown 3D heart tissue (cardiac organoids).

Children and adults who eat more live microbe-rich foods have healthier diets

French children and adults widely consumed foods likely to contain live microbes, mainly yogurt, unpasteurised cheese, fruits, and vegetables. Higher intake was associated with more nutrient-rich diets and better diet quality scores, but the cross-sectional study cannot prove health benefits.
