Fear and worry got you down? Here’s how to calm these feelings.
Have you grown more worried and fearful about life over the years? You aren’t alone. Research has shown that feelings of fear, general anxiety, and nervousness tend to rise with age.
These negative feelings can manifest in many ways. You could be more concerned about your financial future, the risk of a new or returning health problem or injury, or as the recent COVID-19 pandemic has shown, changes in world events.
“People become more fearful about daily life because they worry a setback will come at any time, and it’s something they can’t control,” says Dr. Ipsit Vahia, medical director of Geriatric Psychiatry Outpatient Services at Harvard-affiliated McLean Hospital.
Estudos realizados na Alemanha, nos Estados Unidos e em Cingapura indicam que as células T podem levar à cura de pacientes infectados pelo novo coronavírus sem que estes cheguem a desenvolver anticorpos. Desse modo, podem ser inúteis testes que detectam a presença de anticorpos mesmo para quem comprovadamente contraiu a covid-19. As informações são de reportagem do jornal britânico The Telegraph.
As células T são a parte 2 de uma resposta trifásica à infecção. O vírus começa a se ligar a receptores nas membranas mucosas na parte posterior do nariz e da garganta. Nesse ponto, com a detecção de uma proteína estranha no corpo, a 1ª fase imune entra em ação. As chamadas células imunes “não específicas”, que respondem a qualquer invasor instantaneamente, começam a atacá-la. Se não puderem, o backup é chamado: células T.
Metacognition, thinking about how you think, has been shown to help students improve their grades. Stanford University researchers published a new study that outlines a 15-minute thinking hack that led to an average improvement of one third of a letter grade for the participants.
The research stems from the insight that while many resources are provided by educational institutions, students don’t always know how to use them effectively. Patricia Chen, a postdoctoral research fellow who led the study, hypothesized that if students were made more self-reflective about how they approach their studies and the available resources, they could do better.
