Research shows skeleton to be endocrine organ

...the number of insulin-producing cells and reducing stores of fat. In this published research, authors show that an increase in osteocalcin activity prevents the development of type 2 diabetes and obesity in mice. This discovery potentially opens the door for novel therapeutic avenues for the prevention ...

Conventional plowing is 'skinning our agricultural fields'

...ears. "Returning the organic matter to the soil stores carbon," Montgomery said. "If all farms on the planet were converted to no-till, the range of estimates for sequestered carbon runs from 10 percent of current carbon emissions to about half. "It's probably closer to 10 percent, but even that would...

Sugar and spice and everything nice: Health differences in newborn girls and boys

...d therefore must rely in part on internal nutrient stores to produce energy anaerobically (without oxygen). The end-products of this process (anaerobic metabolism) are lactate and hydrogen ions (H+) which can accumulate in the liver cells during ischemia leading to detrimental affects. Thus, to better und...

Computer graphics spills from milk to medicine

...the milk. Putting the model in reverse, grocery stores could identify spoiled meats, contaminants or other food safety issues if a particular food problem consistently and detectably changed the light scattering properties of the food, said Jensen. The model has already provided insights into the myst...

Why nectar-feeding bats need a 'power drink' to fly

...We found the bats depleted almost 60% of their fat stores each day, but even this phenomenal rate was still barely enough to sustain their metabolism when nectar was absent. This underlines how accurately these bats must balance their energy requirements every day and how vulnerable they are to ecological p...

Genomics study provides insight into the evolution of unique human traits

The scientists also found dramatic gene copy number differences potentially associated with cognition, reproduction, immune function, and ...

New role for protein in fat cells may improve understanding of obesity and diabetes

Scientists find brown fat master switch

...und in brown but not in white fat -- the type that stores excess calories and causes waistlines to bulge. In some of the mouse experiments, the Dana-Farber investigators inserted PRDM16 genes into precursors of white fat, and implanted the white fat precursors under the skin of the animals. The PRDM16 ge...

Insulin sensitizer also serves as energy-conserving signal to the brain

... expenditure in an effort to maintain adequate fat stores during lean times, the researchers report. Energy homeostasis may be mediated by both short-term regulators, such as gut hormones, and long-term regulators, said Takashi Kadowaki of the University of Tokyo. In this study, we identified, for the fir...

Stem cell licensing deal positions Toronto as world leader in technology

...ocess to remove the cells from the cord tissue and stores them for future use. Unlike cord blood stem cells, which can also be harvested, mesenchymal cells are the building blocks for the muscle, bone and connective tissues of the body. HUCPVCs also serve as regulators of the immune system. Published uses ...

University of Colorado invention may allow thirsty crops to signal farmers

... clips to individual plant leaves and collects and stores information, said Seelig. When the leaves lose enough water to contract to a critical width, the sensor can wirelessly signal computers. The computers, for example, could instruct individual pivot irrigation systems used widely on Colorado's east...

Lack of sun does not explain low vitamin D in elderly who are overweight

...g in different climates. However, if low vitamin D stores are not attributed to low sunlight exposure in this population, it suggests that we should explore other possibilities, says Harris. The most likely explanation seems to be that vitamin D is sequestered in fat tissue, reducing its entry into the bloo...

New Brandeis research sheds light on memory by erasing it

In an important study published this week in the Journal of Neuroscience, Brandeis University researchers report for the first time that memory storage can be induced and then biochemically erased in slices of rat hippocampus by manip...

Hot flashes -- Studies explore the role of genes, obesity and alcohol

...d to estrogen, because adipose tissue produces and stores estradiol, the major estrogen in humans. Most people had assumed that obese women would have higher circulating estrogen levels because of this, Flaws said. That assumption turned out to be incorrect, at least for women in midlife. "It could be tha...

UCLA/Toronto researchers unlock key to memory storage in brain

This further strengthened the bond between people and dogs and led to increasing popularity of smaller dogs as companions.

...e. It acts in the brain to tell the body that fuel stores have been restocked and that it can stop feeding. Many individuals who are obese exhibit leptin resistance, that is, they do not respond appropriately to high levels of leptin in their blood. One possible cause of leptin resistance is that leptin onl...
