Nicotine alters gut microbiome differently in males and females, mice study shows

Many people who smoke or chew tobacco can't seem to escape nicotine's addictive properties. Studies show that women in particular seem to have a harder time quitting, even with assistance, when compared to men.

Sonic Hedgehog helps solve mysteries of Parkinson's disease

You may know Sonic Hedgehog as a Sega videogame character who saves us all from world domination. But within the realm of science, Sonic Hedgehog is also helping to solve the mysteries of Parkinson's Disease.

New study sheds light on normal function of Parkinson's gene

A new study published in the journal Neuron sheds light on the normal function of LRRK2, the most common genetic cause for late-onset Parkinson's disease. The study was supported by the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health.

Study sheds new light on why autism is more common in boys

Researchers aiming to understand why autism spectrum disorders (ASD) are more common in boys have discovered differences in a brain signaling pathway involved in reward learning and motivation that make male mice more vulnerable to an autism-causing genetic glitch.

NTU Singapore, KAIST scientists discover new mechanism that causes Parkinsonian symptoms

Scientists from Nanyang Technological University, Singapore and the Korea Advanced Institute of Science & Technology have identified a new mechanism that causes the hallmark symptoms of Parkinson's disease, namely tremors, rigidity, and loss of voluntary movement.

Researchers identify new mechanism that causes hallmark symptoms of Parkinson's disease

A KAIST research team has identified a new mechanism that causes the hallmark symptoms of Parkinson's disease, namely tremors, rigidity, and loss of voluntary movement.

Brain rewiring due to dopamine loss may be source of impaired movement in Parkinson's disease

The brain's own mechanisms for dealing with the loss of dopamine neurons in Parkinson's disease may be a source of the disorder's abnormal movement, according to a Northwestern Medicine study published in Neuron.

New approaches to prevent or treat antipsychotic-induced supersensitivity psychosis

In the current issue of Psychotherapy and Psychosomatic, professor Guy Chouinard, one of the most important psychopharmacologists, provides a synthesis of the data that are concerned with neglected side effects of commonly used psychotropic drugs.

Study finds mechanism behind super-sharp night vision for brief time during total eclipse

If you were fortunate enough to witness the recent total solar eclipse in all its glory, you might have noticed something surprising.

Researchers find mechanism that explains differences in skin’s responsiveness to heat, mechanical stimuli

Researchers at the Bluestone Center for Clinical Research at the New York University College of Dentistry (NYU Dentistry) have identified a novel molecular mechanism which explains why dark-skinned and light-skinned people respond differently to heat and mechanical stimulation.

Existing antidepressant drug could slow progression of Parkinson’s

Michigan State University scientists now have early proof that an antidepressant drug that's been around for more than 50 years could slow the progression of Parkinson's.

Biologists unlock key elements behind animal kinship attachments

A baby lamb is separated from its family. Somehow, in vast herds of sheep that look virtually identical, the lost youngling locates its kin. Salmon swim out to the vast expanses of the sea and migrate back home to their precise spawning grounds with bewildering accuracy.

Reprogrammed stem cell therapy shows promise in Parkinson's

Japanese investigators have found that their experimental stem cell therapy for Parkinson’s disease actually works. In their experimental therapy, the team of researchers “reprogrammed” stem cells to make them neurons and implanted them into the brain of monkeys with a version of Parkinson’s disease. Stem cell therapy showed improvement of symptoms in these patients and was found to be safe. The study was published yesterday, 30th August 2017 in Nature.

Bacterial community in the gut of Parkinson's patients differs from that of healthy people

Parkinson's disease is an insidious disease: by the time it manifests as the typical motor dysfunctions such as tremors or muscle rigidity, portions of the brain have already been irreversibly destroyed.

Researchers use zebrafish animal model to explore drug-seeking behavior

As the opioid crisis escalates, the science behind addiction remains poorly understood. To address this need, researchers at University of Utah Health devised a system that allowed zebrafish, a small tropical fish, to self-administer doses of hydrocodone, an opioid commonly prescribed to people for pain.

Teenagers’ impulsive and risk taking behavior not related to brain deficit symptoms

A popular theory in recent neuroscience proposes that slow development of the prefrontal cortex - and its weak connectivity with brain reward regions - explains teenagers' seemingly impulsive and risky behavior.

Brain scans reveal lower serotonin transporters in people with mild cognitive impairment

In a study looking at brain scans of people with mild loss of thought and memory ability, Johns Hopkins researchers report evidence of lower levels of the serotonin transporter -- a natural brain chemical that regulates mood, sleep and appetite.

ACR develops 3 new guidance documents, revises 32 others to advance science of radiology

The American College of Radiology developed 3 new guidance documents and revised 32 others to advance the science of radiology and improve the quality of service to patients.

Diabetes drug shows promise as Parkinson’s treatment

A drug commonly used to treat diabetes could help people living with Parkinson’s disease, say researchers.

UVA researchers identify connection between dopamine neurons and brain’s circadian center

Neurons in the brain that produce the pleasure-signaling neurotransmitter dopamine also directly control the brain's circadian center, or "body clock" - the area that regulates eating cycles, metabolism and waking/resting cycles - a key link that possibly affects the body's ability to adapt to jet lag and rotating shift work, a new University of Virginia study has demonstrated.
