Third-person self-talk helps control emotion, says study

A study published online in a nature journal Scientific Reports suggests that talking in the third person to oneself in stressful times might help controlling emotions and it needs no additional mental effort than first person self-talk, which is normally used by people to talk to themselves.

Stem cells in the brain found to influence aging in mice

A study conducted by a team of researchers led by Dongsheng Cai at the Albert Einstein College of Medicine, New York, finds that injecting extra stem cells into the hypothalamus in the brain of mice slows down the aging process.

Stem cells in the brain found to regulate aging

Scientists at Albert Einstein College of Medicine have found that stem cells in the brain's hypothalamus govern how fast aging occurs in the body.

Exercise may not be equally effective in males and females, research shows

Healthcare practitioners regularly prescribe diet and exercise as a method for patients to lose weight. But exercise might not be equally effective in males and females, according to new research conducted at the University of Colorado, Anschutz Medical Campus.

Loss of smell linked to weight loss in mice despite same food intake, study reveals

Experiments conducted at the University of California, Berkeley, suggest that the odor of food has a direct link with how the body processes the calories. The new study conducted on mice published in the first week of July in the journal Cell Metabolism implicates that the ability to detect the smell of food is related to whether the calories are burnt rather than stored.

Sense of smell may play key role in how the body deals with calories

Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight.

UA researcher’s findings on estrogen may lead to promising treatment for hot flashes

Fifteen years ago, Dr. Naomi Rance was at work when she experienced her first hot flash. Rance, a physician and researcher at the University of Arizona College of Medicine - Tucson, took note.

Research provides insights into how light may interact with the brain to affect sleep

Humans are diurnal animals, meaning that we usually sleep at night and are awake during the day, due at least in part to light or the lack thereof. Light is known to affect sleep indirectly by entraining--modifying the length of--our circadian rhythms and also rapidly and directly due to a phenomenon known as masking.

Insulin in the brain may help regulate eating behavior and facilitate weight loss, study shows

Eating behavior and the subjective feeling of hunger are regulated by a variety of hormones. Here a key role is played by the hormone insulin because it is not only active in the body, but also in the brain.

Japanese scientists show how male pheromone enhances female sexual behavior in mice

A study by a group of Japanese scientists showed how a male pheromone in mice enhances sexual behaviors in females--and how it may enhance a different behavior, aggression, in males -- by identifying distinct neural circuits and neurons that generate a particular behavioral response to specific chemical signals.

Long-distance brain connections can target, stimulate discrete pools of stem cells

Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the University of Basel reports in the current issue of "Science" that long-distance brain connections can target discrete pools of stem cells in their niche and stimulate them to divide and produce specific subtypes of olfactory bulb neurons

Scientists show how brain circuits govern hunger and cravings

The urge to satisfy hunger is a primal one, but – as any dieter knows – choices about when and what to eat can be influenced by cues in the environment, not just how long it's been since breakfast.

Research reveals link between POMC neurons and release of insulin by the pancreas

The brain is key in the regulation of appetite, body weight and metabolism. Specifically, there is a small group of hypothalamus neurons, called POMC, that detect and integrate signals that inform on the energy state of the organism and activate the appropriate physiological responses.

New study establishes link between prenatal stress and onset of eating disorders

Stress affects the body and can trigger illness -- from psychiatric disorders to heart disease. Humans are exposed to stress at different intensities throughout life -- as children, in adolescence, and in old age. But when is the impact of stress on our systems most powerful? Many researchers maintain that the critical effect occurs prenatally, inside the womb.

Cluster headaches: searching for effective therapies

Cluster headaches are probably the most painful types of pain a human can suffer and it is for no small reason that this condition is also sometimes referred to as suicide headache.

Mice study may help explain why dieting can be inefficient way to lose weight

A study carried out in mice may help explain why dieting can be an inefficient way to lose weight: key brain cells act as a trigger to prevent us burning calories when food is scarce.

UAB professor receives $1.5 million grant to explore links between circadian fluctuations and glaucoma

Brian Samuels, M.D., Ph.D., assistant professor in the University of Alabama at Birmingham Department of Ophthalmology, has received a five-year, $1.5 million grant from the National Eye Institute to explore the links between circadian fluctuations and glaucoma. This is Samuels' first R01 grant.

Newly discovered molecule plays central role in appetite control mechanisms

A newly discovered molecule increases appetite during fasting -- and decreases it during gorging. The neuron-exciting protein, named NPGL - apparently aims to maintain body mass at a constant, come feast or famine. An evolutionary masterstroke, but not great news for those looking to trim down -- or beef up for the summer.

Study finds link between circadian variations in body temperature and arousal in brain-injured patients

For people with severe brain injuries, researchers have found that the rhythm of daily fluctuations in body temperature is related to their level of consciousness, according to a preliminary study published in the April 19, 2017, online issue of Neurology, the medical journal of the American Academy of Neurology.
