The famous axiom 'the enemy of my enemy is my friend' is part of Austrian psychologist Fritz Heider's social balance theory, introduced in the 1940s. Previous studies have tried to model social networks based in famous theory but results remained controversial. New model takes into account two key pieces simultaneously: Not everyone knows everyone else in a social network, and some people are friendlier than others. With those two constraints, large-scale social networks consistently align with social balance theory. Model has broad applications for exploring political polarization, neural networks, drug interactions and more.
Published New study challenges one-size-fits-all approach to vitamin D supplementation guidelines

A new study sheds light on the complexities of achieving optimal vitamin D status across diverse populations. Despite substantial research on the determinants of vitamin D, levels of vitamin D deficiency remain high. Researchers believe their findings have significant implications for the development of tailored recommendations for vitamin D supplementation.

Some neurological disorders can be improved through photobiomodulation, a non-invasive technique based on the application of low-intensity light to stimulate altered functions in specific regions of the body. Now, a study reveals how photobiomodulation applied to the brain-gut axis is effective in recovering some cognitive alterations and sequelae caused by chronic stress. The study opens up new perspectives for applying the technique in future therapies for the treatment of neurological diseases in patients.
Published When working out, males are programmed to burn more fat, while females recycle it--at least in rats

Vigorous exercise burns fat more in males than in females, but the benefits of exercise are broad for everyone.
Published Medical school scientist creates therapy to kill hypervirulent bacteria

Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk include seniors and patients with other health problems such as diabetes, cancer, kidney failure and liver disease.
Published Microneedles and suction cup for blood diagnostics, modeled on leeches

A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing countries.

Combining time-restricted eating with high-intensity functional training may improve body composition and cardiometabolic parameters more than either alone, according to new research.
Published Biomarkers in blood to predict liver cancer

Early detection has the potential to transform treatment and outcomes in cancer care, especially for cancers like liver cancer, which is typically diagnosed at a late stage with limited options for cure. A new study suggests that proteins detectable in the blood could improve predictions about risk of liver cancer years before typical diagnosis.
Published Social-media break has huge impact on young women's body image, study finds

There's a large and growing body of evidence pointing to potentially negative impacts of social media on mental health, from its addictive nature to disruptions in sleep patterns to effects on body image. Now, a new study has found that young women who took a social media break for as little as one week had a significant boost in self-esteem and body image -- particularly those most vulnerable to thin-ideal internalization.

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell adhesion in this phenomenon and pave the way for improved assisted reproductive technology (ART).

Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.
Published Researchers identify causal genetic variant linked to common childhood obesity

Researchers have identified a causal genetic variant strongly associated with childhood obesity. The study provides new insight into the importance of the hypothalamus of the brain and its role in common childhood obesity and the target gene may serve as a druggable target for future therapeutic interventions.
Published Scientists work out the effects of exercise at the cellular level

The health benefits of exercise are well known but new research shows that the body's response to exercise is more complex and far-reaching than previously thought. In a study on rats, a team of scientists has found that physical activity causes many cellular and molecular changes in all 19 of the organs they studied in the animals.
Published Nutrient research reveals pathway for treating brain disorders

The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer's and stroke, mimicking choline so they can be smuggled into the brain.
Published Virtual reality environment for teens may offer an accessible, affordable way to reduce stress

Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.
