The findings show significant overlaps with genes related to neurological disorders and obesity in humans, providing a new framework for studying these connections.
A systematic review by University of Bristol researchers found that consuming low energy sweeteners instead of sugar leads to reduced calorie intake and body weight. The study also suggests that LES beverages may be more effective than water in reducing weight, as they do not increase appetite.
A new study found that children's brains respond differently to high- and low-calorie foods based on their body weight. Children with more lean body mass had a greater brain response to high-calorie foods, while those with higher body fat had reduced activity in the brain when looking at healthier options.
A new Northwestern Medicine study found that walking at an easy pace for three hours a week improves prostate cancer survivors' fatigue, depression, and body weight issues. Non-vigorous walking also showed benefits in these areas, with brisk walking potentially leading to similar improvements.
A study led by Tokyo Medical University researcher Toshihiro Nakajima found that an anti-inflammatory drug can counteract obesity in mice by regulating mitochondrial biogenesis and fatty acid breakdown. The drug, LS-102, inhibits the Synoviolin gene, leading to increased energy control pathways.

The study's findings have important implications for weight management support and advice, as many individuals may not be receiving the help they need due to inaccurate assessments.
A model describes how a person's size determines their carrying capacity, not just body weight. The study reveals that smaller individuals can comfortably carry more pack weight than expected.

A team of scientists discovered that the ancient piranha relative Megapiranha paranensis had a bite force that could crush bone and pierce through thick shells, rivaling even the mighty T. rex. The study, published in Scientific Reports, used computer simulations to estimate the bite forces of living and extinct piranhas.
A new life sciences study using 14 years of data on gray wolves in Yellowstone National Park found that cooperative group behavior and a mother's weight are crucial for raising successful offspring. Larger packs tend to get larger and win the 'arms race' of holding territories against competing packs.
Researchers found that mother wolves' body weight and pack size play a crucial role in enabling pups to survive and thrive. The study suggests that managers can use information on pack size, female wolf weight, and disease prevalence to set harvest limits and ensure sufficient population growth.
A survey of carers and pharmacists found that they often incorrectly calculated paracetamol doses for overweight children. The recommended dose should be adjusted according to the child's actual body weight, but many responders got it wrong. To prevent adverse consequences, simple evidence-based dosing guidelines must be developed.
A team at the University of Vermont discovered that crowdsourcing can effectively predict user behavior, such as body weight and electricity use. The experiment showed that self-directed questions and answers by visitors to websites led to computer models that accurately predicted these outcomes.
Researchers from Max Planck Institute decoded genes for extreme body size in mice, revealing 67 loci and new genes regulating energy balance, metabolic processes, and growth. The study's findings suggest that artificial selection can parallel natural selection to alter similar genes, shedding light on the genetic basis of complex traits.
Researchers at the University of Cincinnati found evidence that BPA can alter the structure of the uterus, leading to increased susceptibility to pyometra, a potentially deadly infection. In animal models, exposure to BPA induced immune cell numbers in the uteri, which were five-fold higher than control animals.
Research found that over half of school children carry rucksacks weighing 10% or more of their body weight, increasing the risk of back problems. Girls are more susceptible to back issues, which worsen with age. Experts advise parents and teachers to promote healthy backpacking habits.
A new clinical trial shows that high doses of 'load' through programmed electrical stimulation of the muscle significantly slows bone density loss in patients with spinal cord injury. Average bone density in the femur was almost 40% lower in patients who received low or no load compared to those who received high load.
Research has found that obesity is associated with neuronal injury in the hypothalamus, a crucial brain region for regulating body weight. Additionally, turnover of nerve cells in this area is inhibited by obesity, indicating a significant impact on energy balance control.
A recent study published in JAMA found that adhering to a healthy lifestyle, including not smoking, exercising regularly, and eating a balanced diet, can significantly lower the risk of sudden cardiac death in women. The study analyzed data from over 81,000 women and found that those who met four key lifestyle criteria had a 92% lower ...
A recent study found that coffee made from capsules contains higher levels of furan, a toxic compound linked to cancer, compared to drip coffee. The levels were highest in espresso and lowest in instant coffee. However, the amounts are still within safe limits for human consumption.
A study found that media exposure to idealized body shapes improves women's body satisfaction, at least initially. However, this effect is often accompanied by increased dieting behavior and ultimately unsustainable body image.
