Coronavirus mutations similar to those in the UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, scientists say.
A team led by University of Cambridge researchers observed the virus mutating in the case of an immunocompromised patient treated with convalescent plasma.
They saw the emergence of a key mutation, also seen in the new variant, that led to the rapid spread of the virus before the country was forced into lockdown in January.
A burgeoning industry in Woorabinda with the potential for international appeal could drastically improve the economic independence of the Central Queensland shire.
Woorabinda Aboriginal Shire Council, conservation organisation Greening Australia, and Rural and Remote Development Consultants announced on Friday they were going ahead with practical testing for large-scale wattleseed production at Woorabinda nearly 20 years after the then-mayor Steven Kemp commissioned a feasibility study into the idea.
The 12 months of testing will involve analysing plant varieties, soil types, and the water requirements needed to sustainably and commercially produce the plant.
Initial funding included $38,000 from Greening Australia and $40,500 from the Department of State Development, but private investment may be required in the long-term.
Worrying new coronavirus variants aren’t just imported they can be home grown
The 45-year-old patient had been sick with coronavirus for months. Doctors had given him the antiviral drug remdesivir to fight the virus, anticoagulation drugs to prevent blood clots, immune modulators to try to control his out-of-control immune response and steroids to fight inflammation.
He’d been home on and off but never seemed able fully recover. His blood oxygen would drop, although tests indicated he was negative for the virus.
Dr. Jonathan Li, who leads a lab at Brigham and Women’s Hospital in Boston studying viruses such as HIV and their mutations, was called in to help study what was going on in the patient.
LONDON All at once, the coronavirus seemed to change.
For months, Dr. Steven Kemp, an infectious disease expert, had been scanning a global library of coronavirus genomes. He was studying how the virus had mutated in the lungs of a patient struggling to shake a raging infection in a nearby Cambridge hospital, and wanted to know if those changes would turn up in other people.
Then in late November, Dr. Kemp made a startling match: Some of the same mutations detected in the patient, along with other changes, were appearing again and again in newly infected people, mostly in Britain.
