Oregon researchers find cell division machinery that makes brain cells
High-resolution imaging of fruit flies at the University of Oregon has captured mechanical motions that stem cells use to make neurons, the cells that make up the brain. These motions coordinate cell division with differentiation, where newly born cells become neurons.

Childhood disadvantage affects brain connectivity
In a new study, researchers have examined how "neighborhood disadvantage" and how it can affect the developing brain, including the brain's connectivity between regions. The study appears in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier.

New study identifies plasticity disparities between patients with brain malformation
Recently published in the scientific journal Brain Communications, a new study distinguished structural patterns between individuals with corpus callosum dysgenesis (CCD), a congenital condition that consists of the absence or incomplete development in the connecting structure between the two brain hemispheres. The research was carried out by the D'Or Institute for Research and Education (IDOR), the University of Pittsburgh, Oswaldo Cruz Foundation (Fiocruz), and the Federal University of Rio de Janeiro (UFRJ).

Maintaining self-control -- The careful balance of the immune system
Researchers from the University of Tsukuba determined in mice that a balance between two receptor molecules, called DNAM-1 and TIGIT, helps tell the immune system whether to fight or hold back. In the absence of DNAM-1, TIGIT can produce more signals that suppress activation of certain immune cells, such as regulatory T cells. The balance between these two receptors may be a novel mechanism that can be therapeutically targeted to fight autoimmune diseases.

Americans who get news from traditional sources more likely to accept COVID-19 vaccine
Americans who get their news from traditional sources (e.g.: TV, newspapers) are more likely to accept the COVID-19 vaccine than those who rely on social media.

Adolescents' well-being and learning during COVID-19 linked to psychological needs
A new survey study suggests that, for adolescents who received unplanned distance education due to the COVID-19 pandemic, experiencing one's own competence was linked to positive emotion, self-motivation to learn, and pro-learning behaviors. Feeling connected to others was also linked to positive emotion. Julia Holzer of the University of Vienna, Austria, and colleagues present these findings in the open-access journal PLOS ONE.

Getting "wind" of the future: Making wind turbines low-maintenance and more resilient
Wind turbines in remote locations with harsh weather often suffer from frequent system failures, increasing cost and yielding unsatisfactory power. Now, in a new study, a global team of researchers suggest and validate a reliable and robust low-cost computation scheme for the simultaneous real time detection and resolution of multiple system faults in wind turbines. Their method paves the way for economical wind mill farms even in challenging environments.

Study of Utah cancer care-at-home model demonstrates lower costs, better outcomes
A study published today in the Journal of Clinical Oncology expands on evidence of lower health care costs and fewer unplanned health care visits in an acute care model of Huntsman Cancer Institute's Huntsman at Home program, which brings cancer care to patients in their homes.

New antimicrobial surface reduces bacteria build-up on medical instruments
Patient infection from urinary catheters are a global health concern. In a world-first, Monash University researchers have developed a new 3D antimicrobial surface to reduce bacterial build-up. The study saw a reduction in bacteria colonisation for three leading Urinary Tract Infection (UTI) pathogens, including E. coli.

Health and the city: Using urban design to promote heart health
Cities harbour a dangerous cocktail of environmental stressors which politicians must tackle to save lives and preserve health. That's the conclusion of a paper published today in European Heart Journal, a journal of the European Society of Cardiology (ESC). "By 2050, three in four people will live in cities, where up to 80% of energy is consumed and 70% of greenhouse gases are emitted," said study author Professor Thomas Münzel

Doctor and mother recounts COVID-19 experience that saw her placed on special ECMO respiratory support and remain in hospital for 150 days
A general practitioner, wife and mother has recounted her experience with COVID-19 which saw her stay in hospital 150 days and become one of the first patients to be treated with extracorporeal membrane oxygenation (ECMO), special equipment that completely takes over the function of the lungs and is a last resort option. The self-written case report appears in the journal Anaesthesia Reports.

Study reveals huge pressures on anaesthesia and critical care workforce and hospitals during winter wave of COVID-19 pandemic, and devastating drop in surgical activity
New research published in Anaesthesia (a journal of the Association of Anaesthetists) shows the huge pressure that anaesthesia and critical care staff in the UK have been under throughout the winter wave of COVID-19, as the number of newly admitted infected patients surged and most planned surgeries, including a substantial number of critical cancer operations, were cancelled.

Did Earth's early rise in oxygen help multicellular life evolve?
Georgia Tech researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when oxygen is scarce, it can't diffuse very far into organisms, so there is an evolutionary incentive for multicellular organisms to be small to ensure most of their cells can still access oxygen.

Rising energy demand for cooling
Climate-related temperature rises will further increase the cooling demand of buildings. A projection by Empa researchers based on data from the NEST building and future climate scenarios for Switzerland shows that this increase in energy demand for cooling is likely to be substantial and could have a strong impact on our future - electrified - energy system.

Strengthening interpersonal relationships helps medical patients live longer
New research from BYU published in PLOS Medicine found that providing medical patients with social support leads to an increased chance of survival and elongation of life. Such findings come at a critical time as doctors and healthcare professionals seek new ways to improve care and decrease mortality.

Researchers develop framework incorporating renewables and flexible carbon capture
As the global energy demand continues to grow along with atmospheric levels of carbon dioxide (CO2), there has been a major push to adopt more sustainable and more carbon-neutral energy sources. Solar/wind power and CO2 capture - the process of capturing waste CO2 so it is not introduced into the atmosphere - are two promising pathways for decarbonization, but both have significant drawbacks.

Saving the eastern monarch butterfly: SFU research
Simon Fraser University researchers are playing a key role in guiding conservation efforts to protect a declining butterfly population. The eastern monarch butterfly, an important pollinating species known for its distinct yellow-orange and black colour, is diminishing due to the loss of the milkweed plant--its primary food source.
