| Slow walking may be to blame for perceived congestion in pedestrian areas Posted: 12 May 2022 06:26 AM PDT When designing public spaces or other places where foot traffic is considered, planners and architects need to know how people perceive the spaces in question. It is commonly believed that a space will feel more congested if the crowd density is higher. However, new research suggests that walking speed of individuals actually plays a greater role than crowd density in how someone feels about a busy space. Also, age and gender seem to affect someone's perception of how congested an enclosed space feels to them. |
| When unconscious, the brain is anything but 'silent' Posted: 12 May 2022 06:26 AM PDT The cerebral cortex is thought to be the seat of conscious processing in the brain. Rather than being inactivated, specific cells in the cortex show higher spontaneous activity during general anesthesia than when awake, and this activity is synchronized across those cortical cells. Improving our understanding of the neuronal mechanisms of general anesthesia could lead to better anesthetic drugs and improved surgical outcomes. |
| Flu causes cardiac complications by directly infecting the heart Posted: 11 May 2022 11:23 AM PDT Researchers have shown for the first time in mice that heart problems associated with the flu are not caused by raging inflammation in the lungs, as has long been predicted. Instead, the electrical malfunctions and heart scarring seen in some of the sickest flu patients are caused by direct influenza infection of cardiac cells. |
| Designer neurons offer new hope for treatment of Parkinson's disease Posted: 11 May 2022 09:36 AM PDT Scientists describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson's destruction of dopaminergic cells. |
| Multiple sclerosis: Glatiramer acetate compatible with breastfeeding, study suggests Posted: 11 May 2022 09:36 AM PDT For patients suffering from multiple sclerosis (MS), becoming a mother is fraught with difficult questions: is it acceptable to continue disease modifying treatment during pregnancy and breastfeeding to keep the disease at bay, or does this put the child at risk? A study on the drug glatiramer acetate can relieve mothers of this concern during the breastfeeding period. A comparative study between children whose mothers had taken the drug while breastfeeding and those who hadn't revealed no significant differences in several infant health outcomes during the first 18 months of life. |
| Novel supramolecular CRISPR-Cas9 carrier enables more efficient genome editing Posted: 11 May 2022 09:36 AM PDT CRISPR-Cas9 is considered a revolutionary gene editing tool, but its applications are limited by a lack of methods by which it can be safely and efficiently delivered into cells. Recently, a research team has constructed a highly flexible CRISPR-Cas9 carrier using aminated polyrotaxane (PRX) that can not only bind with the unusual structure of Cas9 and carry it into cells, but can also protect it from intracellular degradation by endosomes. |

| How a leaky gut leads to inflamed lungs Posted: 11 May 2022 07:49 AM PDT In addition to increased morbidity and impaired lung function after a Streptococcus pneumoniaeinfection in older mice, the researchers also found elevated levels of gut-derived bacteria in the lungs, suggesting that bacteria that migrate from the intestine to the lungs may partially be responsible for the poor outcomes in older individuals. |
| Clues about concussions from the gut Posted: 10 May 2022 12:15 PM PDT Scientists suggest telltale signs of concussions might be found in the gut. By taking blood, stool and saliva samples from 33 football players, the researchers were able to examine the diagnostic potential of the gut's microbiome. They say their findings demonstrate that a simple, objective diagnostic test could be developed to track the impact of concussions and signal when it's safe to return to action. |
| Posted: 10 May 2022 12:14 PM PDT It is well documented that lying during interviews takes up more cognitive energy than telling the truth. A new study found that investigators who used this finding to their advantage by asking a suspect to carry out an additional, secondary, task while being questioned were more likely to expose lie tellers. The extra brain power needed to concentrate on a secondary task (other than lying) was particularly challenging for lie tellers. |
