| Decoy particles trick coronavirus as it evolves Posted: 11 Apr 2022 03:43 PM PDT Decoy nanoparticles mimic cells, attracting viruses to bind to them rather than infecting healthy cells. Researchers tested the strategy against the novel coronavirus and five of its variants, finding it was consistently effective. |
| How to rejuvenate the immune system of elderly people and reduce their risk of infectious disease Posted: 11 Apr 2022 03:43 PM PDT A new study identifies a reason for why older adults are significantly more susceptible to infectious diseases than younger people, a critical societal issue most recently exemplified by the COVID-19 pandemic. |
| Lead as a social determinant of child and adolescent physiological stress and behavior Posted: 11 Apr 2022 01:05 PM PDT Lead is an environmental neurotoxicant that causes neurocognitive deficits and cardiovascular and metabolic disorders. It also disproportionately affects socially disadvantaged communities. The association between lead exposure and children's IQ has been well studied, but few studies have examined the effects of blood lead on children's physiological stress and behavior. Three new studies shed light on how lead can affect children and adolescents' physiological stress and emotional/behavioral development. |

A study suggests that some smokers may have robust mechanisms that protect them from lung cancer by limiting mutations. The findings could help identify those smokers who face an increased risk for the disease and therefore warrant especially close monitoring. |

| Researchers identify potential new treatment for metabolic syndrome Posted: 11 Apr 2022 08:37 AM PDT Metabolic syndrome increases a person's risk for diabetes, heart disease, and stroke, and includes conditions such as obesity, high blood pressure and high blood sugar. In a recent mouse-model study, researchers have furthered their progress to develop a drug to treat metabolic syndrome by identifying a receptor that controls appetite and body weight. |
| Smoking increased in those trying to quit during COVID-19, study shows Posted: 11 Apr 2022 07:14 AM PDT A study showed statistically significant and potentially clinically important differences between those who increased and decreased tobacco use during the pandemic. Among current smokers, 28.2 percent reported increased tobacco use, 17.3 percent reported decreased tobacco use and 54.5 percent reported no change. In addition, there were no reports of relapse among former smokers. |
| Hyperbaric oxygen therapy shows promise for opioid addiction treatment Posted: 11 Apr 2022 07:14 AM PDT Hyperbaric oxygen therapy may help people being treated for opioid addiction reduce their methadone dose and better manage pain and withdrawal symptoms, according to a pair of recent studies. The research team recruited participants enrolled in a local opioid treatment program to test the effects of hyperbaric oxygen therapy, a treatment that involves breathing pure oxygen in a pressurized environment. |
| Certain personality traits associated with cognitive functioning late in life Posted: 11 Apr 2022 07:13 AM PDT People who are organized, with high levels of self-discipline, may be less likely to develop mild cognitive impairment as they age, while people who are moody or emotionally unstable are more likely to experience cognitive decline late in life, according to new research. |
| Innovative technology will use smart sensors to ensure vaccine safety Posted: 11 Apr 2022 07:13 AM PDT A new study enables developers to determine vaccine safety via smart sensors that measure objective physiological parameters. |
| Posted: 11 Apr 2022 07:13 AM PDT A trial which used artificial intelligence to train new teachers to spot potential learning difficulties in pupils found that the approach significantly improved their assessment skills. 178 trainees assessed six fictionalised pupils for potential signs of conditions such as dyslexia and ADHD. Half received feedback in the form of a pre-written 'expert solution', while the others received feedback from AI. In a subsequent test of the quality of their reasoning when predicting potential learning difficulties in pupils, those who received the AI feedback scored 10 percentage points higher than the other group. The researchers suggest that AI may therefore be an effective substitute for close, personal feedback on teacher training programmes when training these skills, if one-to-one support is not available. |
| SARS-CoV-2: Neutralization of BA.1 and BA.2 by therapeutic monoclonal antibodies Posted: 11 Apr 2022 07:13 AM PDT Scientists studied the sensitivity of Omicron BA.1 and BA.2 to nine monoclonal antibodies, some of which are used in pre-exposure prophylaxis in immunocompromised individuals. The scientists showed a loss of neutralizing activity against BA.1 and BA.2 in people treated with two antibody cocktails. |
| Heart issues after COVID-19 uncommon in children and young adults, more research needed Posted: 11 Apr 2022 07:13 AM PDT The new scientific statement details what has been learned about how to treat, manage and even likely prevent cardiovascular complications from the SARS-CoV-2 virus in children and young adults, and calls for more research, including studies following the short- and long-term cardiovascular effects from COVID-19, the disease caused by the SARS-CoV-2 virus. |
| Friend or foe? The immune system collaborates with blood cancer cells Posted: 11 Apr 2022 07:13 AM PDT An international study demonstrates that the body's immune system attacks itself in a rare type of blood cancer. Consequently, treatment should be targeted at the immune system as well, not only the cancer cells. |
| Research helps provide scientific framework for psilocybin use in therapeutic settings Posted: 11 Apr 2022 07:12 AM PDT A new paper provides a scientific framework to help shape the rollout of a program in Oregon that will legally permit the use of psilocybin for therapeutic reasons. |

| Posted: 10 Apr 2022 08:07 AM PDT New research finds that the consumption of healthy plant-based foods, including fruits, vegetables, nuts, coffee, and legumes, is associated with a lower risk of developing type 2 diabetes (T2D) in generally healthy people and support their role in diabetes prevention. |
| Insights into the dynamic ultrastructure of the heart Posted: 08 Apr 2022 02:53 PM PDT What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the heart beating -- almost at a molecular level. |
| From computer to benchtop: Researchers find clues to new mechanisms for coronaviruses infections Posted: 08 Apr 2022 11:30 AM PDT A group of bat viruses related to SARS-CoV-2 can also infect human cells but uses a different and unknown entryway. While researchers are still honing in on how these viruses infect cells, the findings could help in the development of new vaccines that prevent coronaviruses from causing another pandemic. |
| Posted: 08 Apr 2022 07:31 AM PDT A new study finds that liberals and conservatives differ in how they perceive dominance in women, which may influence their likelihood to vote them into political office. |
| Human Lung Chip reveals the effects of breathing motions on lung immune responses Posted: 08 Apr 2022 05:38 AM PDT The mere motions of breathing are known to influence vital functions of the lungs, including their development in babies, the production of air-exchange-enhancing fluid on their inner surfaces, and maintenance of healthy tissue structure. Now, new research has revealed that this constant pattern of stretching and relaxing does even more -- it generates immune responses against invading viruses. |
| How to keep knowledge alive for emergencies Posted: 07 Apr 2022 11:19 AM PDT Researchers have investigated how to prevent knowledge and skills that were learned long ago and are rarely used from getting rusty. |
| Two DNA defense systems behind resilience of 7th cholera pandemic Posted: 07 Apr 2022 11:19 AM PDT Two DNA defense systems protect the bacterial strains responsible for the ongoing seventh cholera pandemic from potentially harmful genetic material and viruses, scientists have found. Their study also shows that the defense systems may have been key in the evolution and success of these strains. |
