The opioid epidemic has boosted the number of organs available for transplant



Posted: 16 May 2018 02:22 PM PDT


The researchers examined 17 years of transplantation records and found no significant change in the recipients' chance of survival when the organ donation came from victims of drug intoxication.


Cannabidiol significantly reduces seizures in patients with severe form of epilepsy



Posted: 16 May 2018 02:22 PM PDT


Cannabidiol (CBD), a compound derived from the cannabis plant that does not produce a 'high,' was shown in a new large-scale, randomized, controlled trial to significantly reduce the number of dangerous seizures in patients with a severe form of epilepsy called Lennox-Gastaut syndrome. This study also is the first to offer information on cannabidiol dosing for patients with treatment-resistant epilepsy.


Novel therapy inhibits complement to preserve neurons and reduce inflammation after stroke



Posted: 16 May 2018 11:46 AM PDT


Researchers report that, after ischemic stroke, the complement system identifies stressed but salvageable neurons for removal by microglial phagocytosis. To preserve these neurons, the investigators designed a novel therapeutic that targets a complement inhibitor to a damage signal expressed after stroke. A single post-stroke injection protected neurons from microglial attack in a preclinical model, reducing neuronal loss.


How the gut influences neurologic disease



Posted: 16 May 2018 10:12 AM PDT


A study sheds new light on the connection between the gut and the brain, untangling the complex interplay that allows the byproducts of microorganisms living in the gut to influence the progression of neurodegenerative diseases.


Intimacy in later life does not slow memory loss



Posted: 16 May 2018 09:37 AM PDT


Older people who enjoy a sexually active and emotionally close relationship with their partner tend to perform better at memory tests than sexually inactive older adults on a short-term basis, but this is not the case over a longer period of time. This is according to a study using data from more than 6000 adults aged 50 and over.


How 'navigational hazards' in metro maps confuse travelers



Posted: 16 May 2018 09:36 AM PDT


Some features in metro maps cause passengers to make substantial mistakes in journey planning, but it may be possible to detect and rectify these with automated software, new research has indicated.


Clues to treating psychoses in mental health patients



Posted: 16 May 2018 09:36 AM PDT


Researchers recently found evidence that boosting how well people at risk for psychosis learn from positive and negative feedback could potentially keep psychosis at bay. The team also found that brain scans using functional magnetic resonance imaging, coupled with behavioral measures, could provide markers for the diagnosis of psychosis risk. Researchers hope findings will help mental health professionals to understand how to better treat their patients with psychoses and prevent the onset of psychosis.


People make different moral choices in imagined versus real-life situations



Posted: 16 May 2018 09:35 AM PDT


Researchers often use hypothetical scenarios to understand how people grapple with moral quandaries, but experimental results suggest that these scenarios may not always reflect real-life behavior. The findings showed that people tend to focus more on the outcome of their decision and less on absolute moral principles when faced with a real-life scenario as opposed to a hypothetical scenario.


C'mon get happy: Upbeat songs by female singers dominate the charts, UCI study finds



Posted: 16 May 2018 07:14 AM PDT


Roll over, Beethoven. Elvis Presley too. Female singers with upbeat dance songs are far more likely to make the bestseller music charts, according to new findings. Yet the number of happy songs has declined in recent years, while more negative tunes are increasing.


Mutation protects against Alzheimer's-like disease in mice



Posted: 16 May 2018 07:14 AM PDT


Researchers have discovered a mutation that can protect against Alzheimer's disease in mice. The study found that a specific mutation can reduce the characteristic accumulation of the amyloid-beta peptide that occurs.


Artificial Intelligence improves stroke and dementia diagnosis in most common brain scan



Posted: 16 May 2018 07:14 AM PDT


Artificial Intelligence improves stroke and dementia diagnosis in commonest form of brain scan.


How humans repress prejudices



Posted: 16 May 2018 07:14 AM PDT


A philosopher has used psychoanalysis to investigate why people are often not aware of their prejudices. In her accounts, she has been elaborating how prejudices can become unconscious.


Stroke prevention drug combo shows promise, study says



Posted: 16 May 2018 05:56 AM PDT


If you've had a minor stroke or a transient ischemic stroke (TIA), taking the clot-preventing drug clopidogrel along with aspirin may lower your risk of having a major stroke within the next 90 days, according to new research.


Drug to treat bleeding may benefit some stroke patients



Posted: 16 May 2018 05:56 AM PDT


Patients with stroke caused by bleeding on the brain (intracerebral hemorrhage) may benefit from receiving a drug currently used to treat blood loss from major trauma and bleeding after childbirth, an international trial has revealed.


Not quite a 'double bind' for minority women in science



Posted: 15 May 2018 01:27 PM PDT


Many studies have shown that both minority and women scientists face disadvantages in reaching the highest levels of their careers. So it would make sense that minority women would face a 'double bind' that would particularly disadvantage them. But a new study using a massive database of scientific articles suggests that minority women actually face what might be called a 'one-and-a-half bind.'


National trial: EEG brain tests help patients overcome depression



Posted: 15 May 2018 01:27 PM PDT


A new study found that measuring electrical activity in the brain can help predict a patient's response to an antidepressant.


In era of #MeToo, majority of employees say their employers fail to take new steps addressing sexual harassment



Posted: 15 May 2018 05:17 AM PDT


The spotlight on workplace sexual harassment since fall 2017 has led to high-profile resignations, terminations and lawsuits. And while the revelations and consequences have prompted ongoing, national conversations about appropriate behavior, only 32 percent of working Americans said that their employer has taken new steps to prevent and address sexual harassment in the workplace, according to a new survey.


Your body is transparentized in a virtual environment



Posted: 15 May 2018 05:17 AM PDT


Researchers have found that visual-motor synchronicity of only the hands and feet can induce a sense of illusory ownership over an invisible body interpolated between virtual hands and feet. This active method to induce a sense of illusory ownership over an invisible body at a distance has potential applications in skill learning/transfer and the concept of body-appearance-irrelevant communication in the future.
