The reason why some people find it so hard to resist finishing an entire bag of chips or bowl of candy may lie with how their brain responds to food rewards, according to researchers who found that when certain regions of the brain reacted more strongly to being rewarded with food than being rewarded with money, those people were more likely to overeat.
A new study featured in the Journal of the Academy of Nutrition and Dietetics found that after drinking a small amount of caffeine, participants consumed 10 percent less at a breakfast buffet provided by researchers, but this effect did not persist throughout the day and had no impact on participants' perceptions of their appetites. Based on these findings, the investigators have concluded that caffeine is not effective as an appetite suppressant and weight-loss aid.
A TGen-led team has identified how DNA methylation is associated with a condition known as non-alcoholic fatty liver disease (NAFLD), which can lead to liver cirrhosis and death, and is one of the leading indicators for liver transplants. In one of the most exacting studies of its kind, TGen scientists found evidence that DNA methylation has a role in the initiation of NAFLD-related fibrosis, according to a study published in the journal Clinical Epigenetics.
A new study investigates the best combination of renewables for providing the lowest cost to power system operators in two of China's provinces best suited to scale up renewable energy.
In a first of its kind randomized trial, researchers from the UCI School of Medicine found therapy dogs to be effective in reducing the symptoms of attention deficit/hyperactivity disorder (ADHD) in children. The study's main outcomes were recently published by the American Psychological Association in the Society of Counseling Psychology's Human-Animal Interaction Bulletin (HAIB). Additional new findings were presented at the International Society for Anthrozoology 2018 Conference held July 2-5 in Sydney, Australia.
Cities can serve as useful proxies to study and predict the effects of climate change, according to a North Carolina State University research review that tracks urbanization's effects on plant and insect species.
In a new study that challenges scientists' presuppositions about the carbon cycle, researchers find that tiny organisms may be playing in outside role in the way carbon is circulated throughout the ocean.
Sulfate samples from an ancient lake bed yield new clues about the 'Boring Billion' years in Earth history between 'oxygenation events' that allowed life as we know it. A Rice University postdoctoral researcher's tests revealed the oxygen anomaly that gave researchers a glimpse into conditions 1.4 billion years ago.
The availability of water from underground aquifers is vital to the basic needs of more than 1.5 billion people worldwide. In recent decades, however, the over-pumping of groundwater, combined with drought, has caused some aquifers to permanently lose their essential storage capacity.
Rats exposed in the womb and during lactation to plasticizing chemicals known as phthalates had fewer neurons and synapses than those that were not exposed, researchers report in a new study. The phthalate-exposed rats had reductions in the size of their medial prefrontal cortex, a brain region that regulates behavior, and showed deficits in cognitive flexibility. The variety of phthalates and quantities used in the study were environmentally relevant to human exposures, researchers said.
