Published Time-restricted eating and high-intensity exercise might work together to improve health
(via sciencedaily.com) 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 Social-media break has huge impact on young women's body image, study finds
(via sciencedaily.com) Original source 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.
Published Cell contractions drive the initial shaping of human embryos
(via sciencedaily.com) Original source 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).
Published Father's gut microbes affect the next generation
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) 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 Women are 40% more likely to experience depression during the perimenopause
(via sciencedaily.com) Original source Women are 40% more likely to experience depression in the perimenopause than those who aren't experiencing any menopausal symptoms, finds a new study.
Published Discovery of an atypical heat shock factor, HSF5, involved in meiotic mechanisms: Implications for male infertility
(via sciencedaily.com) Original source Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.
Published An electrifying discovery may help doctors deliver more effective gene therapies
(via sciencedaily.com) Original source In an effort to improve delivery of costly medical treatments, a team of researchers in electrical engineering has developed a stimulating method that could make the human body more receptive to certain gene therapies.
Published Student links worm behavior to brain disease
(via sciencedaily.com) Original source An undergraduate student turns her honor's thesis into a peer-reviewed publication on schizophrenia research.
Published Uncovering the secret of long-lived stem cells
(via sciencedaily.com) Original source Researchers have discovered that the enzyme cyclophilin A, which is produced in large amounts in hematopoietic stem cells, is key for these cells to retain their regenerative potential and avert the effects of aging via an unexpected mechanism.
Published Loneliness grows as we age
(via sciencedaily.com) Original source Loneliness in adulthood follows a U-shaped pattern: it's higher in younger and older adulthood, and lowest during middle adulthood, reports a new study that examined nine longitudinal studies from around the world. The study also identified several risk factors for heightened loneliness across the whole lifespan, including social isolation, education and physical impairment.
Published An omega-6 fatty acid may reduce the risk for bipolar disorder
(via sciencedaily.com) Original source A genetic propensity to higher circulating levels of lipids containing arachidonic acid, an omega-6 polyunsaturated fatty acid found in eggs, poultry, and seafood, has been found to be linked with a lower risk for bipolar disorder. This new evidence paves the way for potential lifestyle or dietary interventions.
Published Researchers target neurogenesis in new approach to treat Parkinson's disease
(via sciencedaily.com) Original source Researchers have found a way to better control the preclinical generation of key neurons depleted in Parkinson's disease, pointing toward a new approach for a disease with no cure and few effective treatments.
Published Childcare pick-up: A 1-hour window to build healthier eating habits
(via sciencedaily.com) Original source After-care food and drink accounted for about 22% of the day's added sugar and about one-third of the sweet and salty snack foods the children ate, according to a new study.
Published Cranberry extracts could boost microbiota and counter cardiometabolic diseases
(via sciencedaily.com) Original source Cranberry extracts appear to improve intestinal microbiota and help prevent chronic diseases such as diabetes and cardiovascular diseases. The study reported beneficial effects after only four days of use.
Published Microarray patches safe and effective for vaccinating children, trial suggests
(via sciencedaily.com) Original source The first study of the use of microarray patches to vaccinate children has shown that the method is safe and induces strong immune responses. The phase 1/2 randomized trial compared results from the measles and rubella vaccine delivered by a microarray patch, a small sticking plaster-like device with an array of microscopic projections that painlessly penetrate the skin and deliver the vaccine, or by conventional injection with a needle and syringe.
Published Study finds school entry requirements linked to increased HPV vaccination rates
(via sciencedaily.com) Original source A new study shows that school entry requirements are linked to an increase in human papillomavirus (HPV) vaccinations.
Published One in eight grown-ups love extreme tartness
(via sciencedaily.com) Original source For most people, biting into a lemon would leave them puckered up and desperate to lose that sour flavor, but a new study revealed that roughly one in eight adults like intensely sour sensations. The cross-cultural study demonstrated there is a subset of 'sour likers' who enjoy exceptionally sour foods.
