>High-stress jobs can be fatal
Researchers discovered that two specific factors - having a high-stress job and low control over one's work - are correlated with higher mortality rates.
Over 3,000 Americans were tracked in a survey, which found that those with high-stress, low-control jobs were 43% more likely to die than those in lower-risk categories.
The point is not that everyone should quit their jobs in terror. Rather, those with influence over employees' work experience - like company heads and managers - should do as much as possible to increase workers' feelings of autonomy, especially for workers in high-stress jobs, according to Erik Gonzalez-Mulé, an assistant professor at the University of Indiana's Kelley School of Business, who co-authored the study.
Gonzalez-Mulé says one comparatively simple option is to allow people to decide where to work, whether that's from home or, in former times, from a café or other non-office workspace.
>Kids more prepared against virus
Children may be protected from coronavirus because they catch so many colds, scientists have suggested.
Figures from the Office for National Statistics suggest children are just as likely to pick up the virus, but few ever develop serious disease, or even show symptoms.
Now scientists have suggested that children may be resistant because their immune systems are already well primed by the common cold.
The common cold is caused by four different types of coronavirus that circulate in the community and are largely harmless.
But while adults pick up a cold around two to four times a year, school age children catch an average of 12 colds annually, studies have shown.
Professor Sir John Bell, Regius Professor of Medicine, University of Oxford told the House of Lords Science and Technology Select Committee, that it may allow youngsters to build up some ongoing resistance that adults do not have.
"How you respond may be due to the state of your existing immunity to coronaviruses generally," he told peers.
>Negativity raises dementia risk
Persistently engaging in negative thinking patterns may raise the risk of Alzheimer's disease, finds a new University College London-led study.
In the study of people aged over 55, published in Alzheimer's & Dementia, researchers found "repetitive negative thinking" is linked to subsequent cognitive decline as well as the deposition of harmful brain proteins linked to Alzheimer's.
Lead author Dr Natalie Marchant, UCL psychiatry, said: "Depression and anxiety in mid-life and old age are already known to be risk factors for dementia. Here, we found that certain thinking patterns implicated in depression and anxiety could be an underlying reason why people with those disorders are more likely to develop dementia. We hope that our findings could be used to develop strategies to lower people's risk of dementia by helping them to reduce their negative thinking patterns."
>Vaccine shows promising results
China has unveiled the results of the phase 1 and phase 2 clinical trials of an inactivated COVID-19 vaccine candidate, which shows promising results in both safety and efficacy, according to the China National Pharmaceutical Group (Sinopharm).
The vaccine, developed by the Wuhan Institute of Biological Products under the China National Biotec Group (CNBG) affiliated to Sinopharm, involved 1,120 volunteers aged between 18 and 59 in its clinical trials, which started on April 12.
The results revealed a good safety record, with no cases of severe adverse effects found in the clinical trials. The vaccine receivers inoculated with two injections in different procedures and doses have all produced high titers of antibodies.
The CNBG is actively promoting overseas cooperation in the phase 3 clinical trial of the vaccine and has secured the intention of cooperation of several companies and research institutions from other countries.
