一、

We smile because we are happy,and we frown because we are sad.Recent studies suggest that our emotions are driven by their related facial expressions.

This February psychologists at the University of Cardiff in Wales found that people whose ability to frown is lessened by botox injections(肉毒杆菌注射)are happier,on average,than people who can frown.The researchers administered an anxiety and depression questionnaire to 25females,half of whom had received botox injections to stop frowning.The botox injected people reported feeling happier and less anxious in general.

In a related study from March,scientists at the Technical University of Munich found that the botox subjects had much lower activity in the brain circuits(回路)involved in emotional processing and responses—in the amygdala,hypothalamus and other parts of the brain—as compared with controls who had not received treatment.

The concept works the opposite way,too.People who frown during an unpleasant procedure report feeling more pain than those who do not,according to a study published in May2008in the Journal of Pain.Researchers applied heat to the forearms of29participants,who were asked to either make unhappy,neutral or relaxed faces during the procedure.Those who exhibited negative expressions reported being in more pain than the other two groups.

No one yet knows why our facial expressions influence our emotions as they seem to.The associations in our mind between how we feel and how we react may be so strong that our expressions simply end up strengthen our emotions—there may be no evolutionary reason for the connection.

Humans are no strangers to widespread viruses,and each time a vaccine is developed,it gives us hope for the future.Now,the world is waiting for a vaccine to fight COVID-19.

Scientists worldwide have been rolling up their sleeves to work toward an effective novel coronavirus vaccine.

Under the coordination(协调)of the World Health Organization(WHO),up to172 countries have been engaging with the“largest and most diverse COVID-19vaccine portfolio(系列产品)”,a plan known as the COVAX Global Vaccines Facility.

COVAX is a system for joint purchasing and balancing the risks of multiple vaccines.When a vaccine proves to be safe and effective,all countries within the facility will be able to access it, according to Xinhua.

The plan is aimed to ensure that all countries,no matter their economic status,can get the vaccine in a timely manner when one is available.It also makes sure that prices will be kept as low as possible.

“A number of vaccines are now in the final stage of clinical trials,”said WHO Director-General Tedros Adhanom Ghebreyesus on Aug24,adding that the goal of COVAX is to deliver at least2billion doses of a vaccine by the end of2021.

According to the WHO,at present,nine potential vaccines are part of the portfolio.

To guarantee the equal access and fair assignment of COVID-19vaccines,the WHO has said
