A Second Interstellar Visitor Has Arrived in Our Solar System. This Time, Astronomers Think They Know Where It Came From
Live Science - 9 Oct 2019 22:17
When 'Oumuamua passed through our solar system in 2017, no one could figure out where the object came from. But astronomers think they've worked out how Comet 2I/Borisov got here.
Siblings of problem gamblers also impulsive, prone to risk-taking
Science Daily - 9 Oct 2019 21:17
Biological siblings of people with gambling disorder also display markers of increased impulsivity and risk-taking, according to a new psychology study. The findings suggest people with gambling disorder -- a psychiatric...
Uncovering the presynaptic distribution and profile of mitochondria
Science Daily - 10 Oct 2019 00:24
Scientists have provided unprecedented insight into the presynaptic distribution and profile of mitochondria in the developing and mature calyx of Held.
New diagnostic criteria may enable earlier detection of cognitive impairment in women
Science Daily - 10 Oct 2019 00:24
Study finds when verbal memory test cut-offs were tailored to patient sex, more female patients and fewer male patients were considered to have amnesic mild cognitive impairment. This could change the way aMCI diagnoses ...
Virtual review of cancer clinical trial treatment options quicker than conventional method
Science Daily - 10 Oct 2019 00:24
Using virtual, cloud-based, interconnected computing techniques applied to 51,000 variables, researchers reduced the time needed to assess a cancer patient's tumor profile and suitability for clinical trials from 14 to 4...
Social determinant screening useful for families with pediatric sickle cell disease
Science Daily - 10 Oct 2019 00:24
Individuals with sickle cell disease (SCD) face the burdens of chronic illness and often racial disparities, both of which may increase vulnerability to adverse social determinants of health (SDoH). For children with SCD...
Randomized controlled trial suggests healthier diet may directly reduce depression
Science Daily - 9 Oct 2019 22:28
Young adults with depression whose diet is usually unhealthy showed significantly fewer symptoms of depression after eating a healthy diet for three weeks, according to a new study.
Humans have salamander-like ability to regrow cartilage in joints
Science Daily - 9 Oct 2019 22:28
Contrary to popular belief, cartilage in human joints can repair itself through a process similar to that used by creatures such as salamanders and zebrafish to regenerate limbs, researchers found.
New mechanism fueling brain metastasis
Science Daily - 9 Oct 2019 21:24
Scientists described a novel mechanism through which astrocytes, the most abundant supporting cells in the brain, also promote cancer cell growth and metastasis in the brain.
Core symptom of schizophrenia reversed in adult mice
Science Daily - 9 Oct 2019 21:24
Researchers have restored normal working memory to a mouse model of schizophrenia, eliminating a core symptom of the disorder that, in people, has proven virtually impossible to treat.
New method visualizes groups of neurons as they compute
Science Daily - 9 Oct 2019 21:23
Using a fluorescent probe that lights up when brain cells are electrically active, researchers found they can image the activity of many neurons at once, in mice brains. The technique could allow neuroscientists to analy...

Scientists find gender-distinct circuit for depression
Science Daily - 9 Oct 2019 21:23
Depression affects women nearly twice as much as men, but unraveling the brain's blueprint that regulates this behavior, let alone identifying specific molecular differences between sexes, has proven difficult. Researche...
