The brain acts as a profound regulatory centre, controlling myriad processes throughout the body in ways we are only just beginning to understand. In new findings, Australian scientists have shown surprising connections between the brain and regulation of bone mass. One of the key functions of our skeletons is to provide mechanical support. In order to fulfil this role, bone tissue is modified throughout our lives, in response to changing activity levels and body weight. Bone mass increases...

Researchers at the University of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive. In contrast to "every man for himself" interpretations of Charles Darwin's theory of evolution by natural selection, Dacher Keltner, a UC Berkeley psychologist and author...

Even the anticipation of sweets may cause our muscles to start taking up more blood sugar, say researchers reporting in the December issue of Cell Metabolism, a Cell Press publication. That message is delivered via neurons in the brain's hypothalamus containing the chemical known as orexin and the sympathetic nervous system, the studies in mice and rats suggest. Orexin neurons are known to switch on when we are motivated to eat or seek other rewards. They also play a role in active...

Taste stimulation and its anticipation activates muscle glucose metabolism via 'orexin' neurons in the brain and thereby reduces blood glucose level in mice Japanese research group led by Professor Yasuhiko Minokoshi and Dr. Tetsuya Shiuchi, scientists at the National Institute for Physiological Sciences, NIPS, Japan, found that meals stimulated with sweet taste and motivated with its anticipation regularly activates "orexin" in the brain and it stimulates muscle glucose metabolism via the...

Ghrelin, a hormone produced in the stomach, may be used to boost resistance to, or slow, the development of Parkinson's disease, Yale School of Medicine researchers report in a study published in a recent issue of the Journal of Neuroscience. Parkinson's disease is caused by a degeneration of dopamine neurons in an area of the midbrain known as the substantia nigra, which is responsible for dopamine production. Reduced production of dopamine in late-stage Parkinson's causes symptoms such as...

Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin's receptor was linked to a person's ability to infer the mental state of others. Interestingly, this same genetic variation also related to stress reactivity. These findings could have a significant impact in adding to the body of knowledge about the importance of oxytocin,...

A new study carried out at the University of Haifa has found that the oxytocin hormone, known as the 'love hormone,' also affects antisocial behaviors, such as envy and gloating A new study carried out at the University of Haifa has found that the hormone oxytocin, the "love hormone", which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. "Subsequent to these findings, we assume that the hormone is an overall trigger for...

New research suggests that a drug used to treat cancer could possibly stop contractions and even prevent premature labor, BBC News reported. The drug Trichostatin A was tested on tissue taken from 36 women undergoing a caesarean, according to a team of researchers from The Newcastle University. They found that the therapy worked by increasing the levels of a protein that controls muscle relaxation -- a much need treatment, as there are over 50,000 premature births every year in the UK and...

A new study indicates a link between autism and alterations to the oxytocin receptor, OXTR, caused by inherited alterations that do not involve DNA sequence mutation. The study, published in the open access journal BMC Medicine, identified the non-DNA change in 'OXTR' via an autistic child and his mother, who potentially has obsessive-compulsive disorder. Dr Simon Gregory headed up a team from the US, UK and Italy, who analyzed the DNA of 119 people with autism and 54 neurotypical...

Researchers at Duke University Medical Center have uncovered a new genetic signature that correlates strongly with autism and which doesn't involve changes to the DNA sequence itself. Rather, the changes are in the way the genes are turned on and off. The finding may suggest new approaches to diagnosis and treatment of autism. The researchers found higher-than-usual numbers of gene-regulating molecules called methyl groups in a region of the genome that regulates oxytocin receptor expression...

Labor Induction is a process of giving an artificial start to birth with medical intervention or other methods. When an induction is not performed for emergency or other medical reasons, the method is considered an elective process. The decision to induce labor has increased in recent years due to its convenience or because it easily accommodates busy schedules. The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...
