Children suffer consequences, too, when mom and dad argue or have tension in their relationship, experts warn.

Dads, in particular, let the negative emotions and tension from their marriage spill over and harm the bond they have with their child, says a new study's lead author, psychologist Chrystyna D. Kouros, Southern Methodist University, Dallas.

The findings drive home the conclusion that the quality of a marriage is closely tied to each parent's bond with their child, Kouros said.

Laboratory mice are one of the most common animal models used in biological and medical research. Thousands of laboratory mouse strains are produced by artificial selection – the process by which humans breed animals over dozens of generations for particular traits.

Patients with implanted artificial cochlea often complain that they cannot recognize speech well in natural environments, especially if background of noise is present. Researchers think that a poor ability to localize sound in a complex auditory environment is responsible for the weak speech perception observed under these conditions. Pentobarbital anesthesia prolongs the recovery time of responses to lagging stimulus.

Many previous chronobiological studies have reported on detection of circadian fluctuation in performing simple motor tasks, fine skilled movement, and anaerobic exercise. However, to the best of our knowledge, literature concerning variation of sensory function according to the circadian cycle is lacking.

Diffuse lesions involving the posterior quadrant (PQ) of the cerebral hemisphere (temporal, parietal, and occipital lobes) induce intractable epilepsy. These patients are potential candidates for surgical treatment. Maintenance of isolated nerve tissue activity after surgery plays a crucial role in the neuroprotective effects of neurosurgery treatment. Shaoya Yin and colleagues from Tianjin Huanhu Hospital in China selected two patients with temporal-parietal-occipital (PTO) intractable epilepsy to receive posterior quadrant disconnection.

Dental researchers at the University of Adelaide are warning parents of the dangers of soft drinks, fruit juice, sports drinks and other drinks high in acidity, which form part of a "triple-threat" of permanent damage to young people's teeth.

For the first time, researchers have been able to demonstrate that lifelong damage is caused by acidity to the teeth within the first 30 seconds of acid attack.

Magnetic resonance spectroscopy can quantitatively analyze in vivo abnormalities of biochemical metabolism within brain tissue in a noninvasive and non-radioactive manner. Compared with 3.0T magnetic resonance spectroscopy, high-field magnetic resonance spectroscopy (≥ 7.0T) exhibits high spatial resolution and density resolution, microscopic imaging of the living body, and obtains both high scanning resolution and result precision within a shorter scan time, thus providing a higher value in clinical diagnosis. In a recent study reported in the Neural Regeneration Research (Vol.

Levodopa is the preferred treatment for Parkinson's disease in the clinic. However, long-term use of levodopa may lead to various motor complications, among which levodopa-induced dyskinesia is the most common, severely affecting patients' quality of life. Dr. Jiancheng He and co-workers from Shanghai University of Traditional Chinese Medicine in China established a model of Parkinson's disease dyskinesia in rats, and treated these animals with Compound Formula Rehmannia.

A Japanese research group led by Prof Norihiro Sadato, a professor of the National Institute for Physiological Sciences (NIPS), National Institutes of Natural Sciences (NINS), has found that people with autism spectrum disorders (ASD) have decreased activity in an area in the brain critical for understanding if his/her movement was imitated by others.

When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell's fate. Until now, only concentration of the chemical signals was thought to matter in determining if the cell would become, for example, muscle, skin, brain or bone.

"Physics summer work, please help!!!," a post on Yahoo! Answers begins. "I cant figure out how to do this anywhere!!! Best answer awarded? Need help immediately!!!!!."

Scientists at the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg have grafted neurons reprogrammed from skin cells into the brains of mice for the first time with long-term stability. Six months after implantation, the neurons had become fully functionally integrated into the brain. This successful, because lastingly stable, implantation of neurons raises hope for future therapies that will replace sick neurons with healthy ones in the brains of Parkinson's disease patients, for example.

Autism does not appear to be solely caused by a deficiency of oxytocin, but the hormone's universal ability to boost social function may prove useful in treating a subset of children with the developmental disorder, according to new findings from the Stanford University School of Medicine and Lucile Packard Children's Hospital Stanford.

The happiness of over 18,000 people worldwide has been predicted by a mathematical equation developed by researchers at UCL, with results showing that moment-to-moment happiness reflects not just how well things are going, but whether things are going better than expected.

A triple therapy for glioblastoma, including two types of immunotherapy and targeted radiation, has significantly prolonged the survival of mice with these brain cancers, according to a new report by scientists at the Johns Hopkins Kimmel Cancer Center.
