  • A different coronavirus outbreak in late 2019 made many dogs in the UK very ill.
  • The strangeness of the disease led veterinarians to send questionnaires to their peers and pet owners.
  • The findings point toward the need for better systems to identify disease outbreaks in animals.

  • Bioelectronic medicine is an emerging field that focuses on manipulating the nervous system to treat diseases.
  • Clinical studies show that using electronic devices to stimulate the vagus nerve is effective at treating inflammatory diseases like rheumatoid arthritis.
  • Although it's not yet approved by the US Food and Drug Administration, vagus nerve stimulation may also prove effective at treating other diseases like cancer, diabetes and depression.

7 dimensions of depression, explained

From baboon hierarchies to the mind-gut connection, the path to defeating depression starts with understanding its causes.

  • According to the World Health Organization, more than 264 million people suffer from depression. It is the leading cause of disability and, at its worst, can lead to suicide. Unfortunately, depression is often misunderstood or ignored until it is too late.
  • Psychologist Daniel Goleman, comedian Pete Holmes, neuroscientist Emeran Mayer, psychiatrist Drew Ramsey, and more outline several of the social, chemical, and neurological factors that may contribute to the complex disorder and explain why there is not a singular solution or universal "cure" that can alleviate the symptoms.
  • From gaining insight into how the brain-gut connection works and adopting a more Mediterranean diet, to seeking help from medical or spiritual practitioners, depression is a personal battle that requires a personalized strategy to keep it at bay, as well as more research and understanding.

  • The first human cases of COVID-19 (subsequently named SARS-Cov-2) were first reported by officials in Wuhan City, China, in December 2019. The first cases of the virus in Europe were discovered at the end of January 2020.
  • Although there were really no preventative measures that could have completely stopped the pandemic, a new study takes a retrospective look at the months preceding the rapid spread of this virus.
  • Researchers suggest that, in a successive phase of the pandemic (or any pandemic), monitoring social media could help public health authorities mitigate the risks of a contagion resurgence.
