| Neutrons produce first direct 3-D maps of water during cell membrane fusion Posted: 20 Sep 2018 02:52 PM PDT New 3-D maps of water distribution during cellular membrane fusion are accelerating scientific understanding of cell development, which could lead to new treatments for diseases associated with cell fusion. |
| TINY cancer detection device proves effective in Uganda testing Posted: 20 Sep 2018 01:10 PM PDT About half the size of a lunch box, the Tiny Isothermal Nucleic acid quantification sYstem (or TINY) has shown promise as a point-of-care detector of Kaposi sarcoma-associated herpesvirus (KSHV) in resource-limited settings such as sub-Saharan Africa. |
| Smart pills dumb down medical care, experts warn Posted: 20 Sep 2018 01:10 PM PDT Enthusiasm for an emerging digital health tool, the smart pill, is on the rise but researchers caution health care providers and policymakers to slow down when it comes to allowing this technology in patient care settings. |
| Preventing a dengue outbreak at the 2020 Summer Olympics Posted: 20 Sep 2018 01:10 PM PDT New controls and frameworks are recommended to detect dengue and other infectious diseases and help prevent their spread during the 2020 summer Olympics and Paralympics being held in Tokyo, researchers report. |
| Human skeletal stem cells identified Posted: 20 Sep 2018 01:10 PM PDT Human skeletal stem cells that become bone, cartilage, or stroma cells have been isolated from fetal and adult bones. This is the first time that skeletal stem cells, which had been observed in rodent models, have been identified in humans. The researchers were also able to derive the skeletal stem cells from human induced pluripotent stem cells, opening up new therapeutic possibilities. |
| Scientists grow human esophagus in lab Posted: 20 Sep 2018 01:10 PM PDT Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids. This is the first time scientists have been able to grow human esophageal tissue entirely from pluripotent stem cells (PSCs), which can form any tissue type in the body. |
| Drug overdose epidemic has been growing exponentially for decades Posted: 20 Sep 2018 01:10 PM PDT Death rates from drug overdoses in the US have been on an exponential growth curve that began at least 15 years before the mid-1990s surge in opioid prescribing, suggesting that overdose death rates may continue along this same historical growth trajectory for years to come. These findings suggest that, to be successful, prevention efforts must extend beyond control of specific drugs to address deeper factors driving the epidemic. |
| Novel biomarker found in ovarian cancer patients can predict response to therapy Posted: 20 Sep 2018 01:10 PM PDT Researchers have identified an independent prognostic factor, cancer/testis antigen 45, that is associated with extended disease-free survival for women with advanced ovarian cancer. Patients with high levels of CT45 in their tumors lived more than seven times as long as patients who lacked sufficient CT45. |
| Gut sense: Neural superhighway conveys messages from gut to brain in milliseconds Posted: 20 Sep 2018 01:10 PM PDT Searching for a more direct connection between the gut and the brain, researchers were shocked to see that distance spanned by a single synapse, relaying the signal in less than 100 milliseconds, less than the blink of an eye. The finding has profound implications for the understanding of appetite and appetite suppressants, most of which target slow-acting hormones rather than fast-acting synapses. |
| A naturally occurring antibiotic active against drug-resistant tuberculosis Posted: 20 Sep 2018 01:08 PM PDT Researchers have discovered that a naturally occurring antibiotic called kanglemycin A is effective against Mycobacterium tuberculosis, the bacteria that cause tuberculosis, even in drug-resistant strains. |
| Why do people share? It's contagious, six-year study of Hadza people shows Posted: 20 Sep 2018 08:55 AM PDT In the modern world, people cooperate with other people including strangers all the time. We give blood, tip providers of various services, and donate to charity even though there is seemingly nothing in it for us. Now, researchers who've studied Hadza hunter-gatherer people in Tanzania over a six-year period have new and surprising insight into why people work together. |
| How lactoferrin clamps down on free roaming iron ions to stop nefarious effects on cells Posted: 20 Sep 2018 08:55 AM PDT What prevents our cells being damaged due to overexposure to iron ions is a protein called lactoferrin, known for its ability to bind tightly to such ions. Researchers used a combined experimental and molecular dynamics simulation to study the changes in the structure of lactoferrin as it binds to iron ions. |
| Even the best healthcare facilities can do more to prevent infections Posted: 20 Sep 2018 08:55 AM PDT Healthcare-associated infections can be reduced by up to 55 percent by systematically implementing evidence-based infection prevention and control strategies, according to a review of 144 studies. The study suggests that there is considerable room for improvement in infection prevention and control practices, regardless of the economic status of the country. |
| In depression the brain region for stress control is larger Posted: 20 Sep 2018 08:55 AM PDT Although depression is one of the leading psychiatric disorders, its cause remains unclear. A recent study found that those affected by depressive disorder have a larger hypothalamus compared to their healthy counterparts. This could explain why many sufferers show increased levels of the stress hormone cortisol and are very often afflicted with periods of tension. |
| Intestines modify their cellular structure in response to diet Posted: 20 Sep 2018 08:55 AM PDT Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility. |
| Nerve cells in the human brain can 'count' Posted: 20 Sep 2018 08:55 AM PDT How do we know if we're looking at three apples or four? Researchers were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities. A similar effect can be observed for digits: In humans, the neurons activated in response to a '2' are for instance not the same as the neurons activated for a '5'. |
| Researchers patent technology for smart seat cushion, adaptable prosthetics Posted: 20 Sep 2018 08:55 AM PDT Researchers have patented a smart seat cushion that uses changes in air pressure to redistribute body weight and help prevent the painful ulcers caused by sitting for long periods of time in a wheelchair. The same technology can be used to create prosthetic liners that adapt their shape to accommodate changes in body volume. |
| Mathematics meets biology to uncover unexpected biorhythms Posted: 20 Sep 2018 08:55 AM PDT A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles. |
| Sample size matters in multisensory integration studies Posted: 20 Sep 2018 08:55 AM PDT Sample size (the number of individuals examined for a study) is the most important factor determining the accuracy of the study results. |
| Fish-rich diets in pregnancy may boost babies' brain development Posted: 20 Sep 2018 07:22 AM PDT Women could enhance the development of their unborn child's eyesight and brain function by regularly eating fatty fish during pregnancy. This is the suggestion from a small-scale study. The research supports previous findings that show how important a prospective mother's diet and lifestyle choices are for the development of her baby. |
| Simulations of every woman's breast tissue address delay on enhanced MRI cancer detection Posted: 20 Sep 2018 07:21 AM PDT Researchers have simulated how over 20 different breast tissue ratios respond to heat given off by MRIs at higher field strengths than available in hospitals today. |
| Anti-cancer drugs may hold key to overcoming antimalarial drug resistance Posted: 20 Sep 2018 07:21 AM PDT Scientists have found a way to boost the efficacy of the antimalarial drug artemesinin with the help of chemotherapy medicines. Artemisinin works through a 'double whammy' attack on the deadly parasite. The drug damages proteins in malaria parasites and clogs the parasite's waste disposal system, known as the proteasome, which chemo can target. |
| Immediate compression could help prevent complications after deep-vein thrombosis Posted: 20 Sep 2018 07:21 AM PDT People with deep-vein thrombosis (DVT) can substantially cut their risk of potentially debilitating complications by starting adequate compression therapy in the first 24 hours of DVT therapy (known as the acute phase of treatment), suggests a new study. |
| American girls read and write better than boys Posted: 20 Sep 2018 07:21 AM PDT As early as the fourth grade, girls perform better than boys on standardized tests in reading and writing, and as they get older that achievement gap widens even more. |
| Analysis of sea squirt embryo reveals key molecules in dopaminergic neuron differentiation Posted: 20 Sep 2018 07:21 AM PDT Researchers have used a novel approach for analyzing the central nervous system of a proto-vertebrate to identify a regulatory cocktail that induces the creation of dopaminergic neurons/coronet cells, a primitive version of the hypothalamus. The findings shed more light on how neurons differentiate into particular subtypes, with potential implications for the treatment of conditions such as Parkinson's disease. |
| Hidden costs of cobalt mining in DR Congo Posted: 20 Sep 2018 07:21 AM PDT Cobalt mining comes at a great cost to public health in the Democratic Republic of the Congo. New research reveals that children are particularly vulnerable: their urine and blood samples contain high concentrations of cobalt and other metals. |
| New test procedure accelerates the diagnosis of multi-resistant hospital pathogens Posted: 20 Sep 2018 07:11 AM PDT The diagnosis of multi-resistant hospital pathogens is now possible in 45 minutes instead of 72 hours. Further research is necessary before the procedure is ready for clinical application. |
| Fatty acids can slow down an overheated immune system Posted: 20 Sep 2018 07:11 AM PDT The STING protein is normally an important part of our immune system, but in some autoimmune diseases it is itself the source of the disease. The pharmaceutical industry is therefore engaged in a race to find a drug that can inhibit STING. Now, researchers may have found it. |
| Test could detect patients at risk from lethal fungal spores Posted: 20 Sep 2018 04:59 AM PDT Scientists have discovered a genetic mutation in humans linked to a 17-fold increase in the amount of dangerous fungal spores in the lungs. The study could allow doctors to screen patients at risk from Aspergillus, and could easily be developed into a test. |
| Crunched for time? High-intensity exercise gives same cell benefits in fewer minutes Posted: 20 Sep 2018 04:58 AM PDT A few minutes of high-intensity interval or sprinting exercise may be as effective as much longer exercise sessions in spurring beneficial improvements in mitochondrial function, according to new research. |
| Can a common heart condition cause sudden death? Posted: 20 Sep 2018 04:58 AM PDT About one person out of 500 has a heart condition known as hypertrophic cardiomyopathy (HCM). This condition causes thickening of the heart muscle and results in defects in the heart's electrical system. Under conditions of environmental stress such as exercise, HCM can result in sudden death. In other cases, patients may go undiagnosed, with their heart function declining gradually over decades. |
| High gluten diet in pregnancy linked to increased risk of diabetes in children Posted: 19 Sep 2018 05:03 PM PDT A new study suggests that a high gluten intake by mothers during pregnancy is associated with an increased risk of their child developing type 1 diabetes. |
| Discovery could explain failed clinical trials for Alzheimer's, and provide a solution Posted: 19 Sep 2018 05:03 PM PDT A vicious feedback loop underlying brain degeneration in Alzheimer's disease may explain why so many drug trials have failed, according to researchers. Their study also identifies a clinically approved drug which breaks the vicious cycle and protects against memory-loss in animal models of Alzheimer's. |
| Understanding epilepsy in pediatric tumors Posted: 19 Sep 2018 10:39 AM PDT Researchers have identified a neuronal BRAF somatic mutation that causes intrinsic epileptogenicity in pediatric brain tumors. |
| Can video game exercises help chronic low back pain? Posted: 19 Sep 2018 10:39 AM PDT Home-based video-game exercises can reduce chronic low back pain in older people by 27 percent, which is comparable to benefits gained under programs supervised by a physiotherapist, new research has found. |
| Newborn opioid withdrawal requires a 'cascade of care,' study suggests Posted: 19 Sep 2018 10:30 AM PDT A new study reports that effective management of neonatal abstinence syndrome (NAS) -- withdrawal symptoms occurring in infants exposed to opioids in utero -- requires a coordinated 'cascade of care' from prevention through long-term follow-up. |
| If pigeons were brilliant, would they flock? Posted: 19 Sep 2018 10:30 AM PDT Researcher looked at how people behave in simple reasoning games and found that people are usually driven to 'flock,' or behave similarly to others in a given situation. |
| A little labeling goes a long way Posted: 19 Sep 2018 10:30 AM PDT New research reveals that infants can use even a few labeled examples to spark the acquisition of object categories. Those labeled examples lead infants to initiate the process of categorization, after which they can integrate all subsequent objects, labeled or unlabeled, into their evolving category representation. |
| New insights into the way the brain combines memories to solve problems Posted: 19 Sep 2018 08:15 AM PDT Current theories do not easily explain how people can use their episodic memories to arrive at novel insights. New research provides a window into the way the human brain connects individual episodic memories to solve problems. |
| New method enables accurate diagnosis of Alzheimer's disease Posted: 19 Sep 2018 08:15 AM PDT A new brain imaging method can show the spread of specific tau protein depositions, which are unique to cases with Alzheimer's. |
| Getting help with parenting makes a difference -- at any age Posted: 19 Sep 2018 08:15 AM PDT Parenting interventions for helping children with behavior problems are just as effective in school age, as in younger children, a new study finds. |
| Cell mechanism regulating protein synthesis in stress conditions discovered Posted: 19 Sep 2018 08:15 AM PDT New research has uncovered the mechanism used by cells to optimize the production of proteins in stressful situations by altering tRNA abundance. |
| Heartbeat paces learning, study finds Posted: 19 Sep 2018 08:15 AM PDT A new study shows that the processing of external information varies during the phases of the cardiac cycle. |
| Difficult people have most to gain from practicing compassion Posted: 19 Sep 2018 08:15 AM PDT New research finds that the most disagreeable individuals, who are also the least likely to be kind, can benefit most from behaving more compassionately. |
| What your cell phone camera tells you about your brain Posted: 19 Sep 2018 08:15 AM PDT Your brain is structured to make the best possible decision given its limited resources, according to new research that unites cognitive science and information theory -- the branch of mathematics that underlies modern communications technology. |
| No increased risk of lung infections among infants using popular anti-reflux medicines Posted: 19 Sep 2018 07:10 AM PDT New research shows infants using popular anti-reflux medicines like omeprazole are not at increased risk of pneumonia or other lower respiratory tract infections, contrary to findings from other international studies. |
