Think chimpanzee beds are dirtier than human ones? Think again



Posted: 16 May 2018 02:23 PM PDT


Chimpanzees (Pan troglodytes) appear to keep tidier sleeping arrangements than humans do. That's one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night.


The mystery of lime-green lizard blood



Posted: 16 May 2018 02:23 PM PDT


Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards remain healthy with levels of green bile that are 40 times higher than the lethal concentration in humans.


Alternative treatment for mild asthma



Posted: 16 May 2018 02:23 PM PDT


People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option.


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.


Individualized ovarian, brain cancer therapies



Posted: 16 May 2018 10:12 AM PDT


Researchers have discovered that a molecular communication pathway -- thought to be defective in cancer -- is a key player in determining the effectiveness of measles virus oncolytic cancer treatment in ovarian and aggressive brain cancers. This discovery enabled researchers to develop an algorithm to predict treatment effectiveness in individual patients.


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.


Exploration of diverse bacteria signals big advance for gene function prediction



Posted: 16 May 2018 10:12 AM PDT


Scientists have developed a workflow that enables large-scale, genome-wide assays of gene importance across many conditions. The study, 'Mutant Phenotypes for Thousands of Bacterial Genes of Unknown Function,' has been published in the journal Nature and is by far the largest functional genomics study of bacteria ever published.


New nuclear RNA retention activity discovered



Posted: 16 May 2018 10:11 AM PDT


Gene expression involves mRNA transport from its place of synthesis to the cytoplasm where protein translation occurs. However, many non-coding RNA species do not follow this flow and new data now demonstrate how cells prevent the unwanted export of RNA and instead ensure nuclear degradation.


An electronic rescue dog



Posted: 16 May 2018 10:11 AM PDT


Scientists have developed the smallest and cheapest ever equipment for detecting people by smell. It could be used in the search for people buried by an earthquake or avalanche.


Diagnosing breast cancer with an imaging pill



Posted: 16 May 2018 09:37 AM PDT


For women, mammograms are a sometimes uncomfortable, but necessary, annual ritual. But this procedure doesn't always provide accurate results, and it exposes women to X-rays. In a new study, scientists report that they have developed a non-invasive 'disease screening pill' that can make cancerous tumors light up when exposed to near-infrared light in mice without using radiation.


Beef peptides block bitter tastes



Posted: 16 May 2018 09:37 AM PDT


From burgers to steaks, beef has a long history of being a delicious part of dinner. But what if that pleasant experience of eating beef could extend beyond the dinner plate? Now, one group reports that beef protein, when broken down into peptides, can block bitter taste receptors on the tongue. Such peptides could someday be used to make other foods and even medicines taste better.


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.


Wearable technology and AI to predict the onset of health problems



Posted: 16 May 2018 09:37 AM PDT

The study found that the data from wearable sensors and artificial intelligence that assesses changes in aerobic responses could one day predict whether a person is experiencing the onset of a respiratory or cardiovascular disease.


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.


Plug-and-play diagnostic devices



Posted: 16 May 2018 07:23 AM PDT


Researchers have developed modular blocks that can be put together in different ways to produce diagnostic devices. These 'plug-and-play' devices can test blood glucose levels in diabetic patients or detect viral infection, among other functions.


Exercise beats genetics in determining amount of body fat



Posted: 16 May 2018 07:23 AM PDT


With obesity now a global epidemic, there is increased focus on risk factors that contribute to weight gain, especially in postmenopausal women. Although many women may blame genetics for their expanding waistlines, a new study shows that as women age they are more likely to overcome genetic predisposition to obesity through exercise.


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.


Per-capita end-of-life spending is decreasing rapidly, according to new study



Posted: 16 May 2018 07:14 AM PDT


Health economists have long considered end-of-life spending to be one of the major contributors to the overall increase in health spending in the United States. That narrative has been supported by recent research findings that increased use of hospice care costs more than it saves, that end-of-life care intensity has been increasing, and end-of-life intensive care unit has accelerated.


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 electronic health records can benefit clinical trials



Posted: 16 May 2018 07:14 AM PDT


A new study has indicated that the Secure Anonymized Information Linkage (SAIL) Databank can provide a simple, cost-effective way to follow-up after the completion of randomized controlled trials.


Cell type switch helps colon cancer evade treatment, study suggests



Posted: 16 May 2018 07:14 AM PDT


Researchers have discovered that colon cancers are often resistant to existing drug treatments because they are composed of two different cell types that can replace each other when one cell type is killed. The study suggests that combination therapies targeting both cell types at once may be more effective at treating colorectal cancer, the third highest cause of cancer-related death in the United States.


Researchers take key step toward growing human organs in laboratory



Posted: 16 May 2018 07:14 AM PDT


Researchers have learned that precursor cells for skeletal muscles actually also give rise to neurons, blood vessels, blood cells and immune cells, pushing science one step closer to generating body parts in a laboratory.


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.


Method to overcome false positives in CT imaging for lung cancer



Posted: 15 May 2018 01:28 PM PDT

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.


Keeping kids with asthma out of the hospital



Posted: 15 May 2018 11:46 AM PDT


Only multimodal interventions that combined multiple categories were effective at reducing the risk of readmission for pediatric asthma between 30 days and one year after initial discharge, Children's research finds.


Biologists find mechanisms that control where transcription factors bind



Posted: 15 May 2018 11:25 AM PDT


A team of biologists has determined how transcription factors, which guide gene regulation, function differently in embryonic development. The results help illuminate how cells acquire distinct functions as the embryo matures.


Targeted biopsy for prostate cancer more effective than traditional method



Posted: 15 May 2018 10:15 AM PDT


Researchers have found that MRI fusion biopsy -- coupling MRI and ultrasound to visualize suspicious lesions in the prostate gland and targeting the biopsy to that particular area -- outperformed standard prostate biopsy in patients with a prior negative prostate biopsy.


Superbug MRSA infections less costly, but still deadly



Posted: 15 May 2018 10:15 AM PDT


Drug-resistant staph infections continue to be deadlier than those that are not resistant and treatable with traditional antibiotics, but treatment costs surprisingly are the same or slightly less, a new national analysis shows.
