‘I felt betrayed’: how Covid research could help patients living with chronic fatigue syndrome

Posted on by

People with ME/CFS face debilitating symptoms but often feel dismissed by doctors. The focus on long Covid could help change that

In the fall of 2016, Ashanti Daniel, a nurse in Beverly Hills, California, went to an infectious disease physician looking for answers about a weird illness she couldn’t shake. After falling sick with a virus four months earlier, she still felt too tired to stand up in the shower.

The appointment lasted five minutes, she said. The doctor didn’t do a physical exam or check her vitals. His assessment: her illness was psychogenic, resulting from something psychological.

Fishermen alerted authorities to ‘suspicious’ items floating in the sea

The Algerian coastguard has seized almost half a tonne of cocaine after fishers alerted authorities to “suspicious” items floating off the north-west coast.

The coastguard fished out 490kg (1,080 pounds) of cocaine split up into 442 packages from the water six nautical miles (11 kilometres) off Oran’s Cap Carbon on Saturday evening, a defence ministry statement said on Monday.

Now is not the time to abandon all Covid caution

Analysis: scientists say the Delta variant should make the government think twice about resting all its hopes on vaccines

If the new health secretary is to be believed, we are about to embark on an “exciting new journey” come 19 July. Sajid Javid, like the prime minister, appears confident that restrictions will be lifted irreversibly on that date. The data, however, is beginning to tell a different story.

When Boris Johnson said his government would be guided by “data, not dates”, the scientific community – for the most part – endorsed the cautious approach. Now, the signs are ominous. Driven by the highly transmissible Delta variant, cases are once again starting to rise exponentially. Vaccination rates have slowed. An exhausted NHS is seeing a rise in hospitalisations. Over half of all people in the UK are not fully vaccinated.

Mixing Covid vaccines offers strong immune protection – study

Posted on by

Oxford researchers say having AstraZeneca then Pfizer jabs is almost as potent as two shots of Pfizer

Having different Covid vaccines for first and second shots produces a strong immune response to the virus, according to research that will help improve the resilience of vaccine programmes around the world.

Scientists in Oxford looked at the impact of a mix-and-match approach to vaccinations where people were given either the standard two shots of Oxford/AstraZeneca or Pfizer/BioNTech vaccine, or a combination of the two.

Vaccine inequality: how rich countries cut Covid deaths as poorer fall behind

Developed countries are seeing the benefits of quickly vaccinating their populations, but concerns remain about the unequal share of global vaccine supplies

New analysis by the Guardian has confirmed that a speedy Covid vaccination campaign pays off when it comes to escaping the worst of the pandemic.

As the chart below shows, countries such as Israel, the UK and the US have all seen deaths decline as vaccination coverage extended to the most vulnerable in their societies.

Covid live news: Luxembourg PM ‘tests positive for Covid’; UK records 14,876 new cases

Xavier Bettel in isolation after self-test result, according to reports; UK’s daily cases figure falls slightly from Saturday

France reported 1,345 coronavirus patients in intensive care today - four less than yesterday - and updated its overall death toll to 84,512, reports Reuters.

UK opposition leader Keir Starmer says there are “huge questions still to answer” following the resignation of health minister Matt Hancock.

Asked if Sajid Javid is a good replacement for Hancock, who resigned after footage emerged of him kissing an aide, PA reports that the Labour leader said:

We need a strong Health Secretary as we come through the pandemic.

But obviously there’s huge questions still to answer. If anybody thinks that the resignation of Matt Hancock is the end of the issue, I think they’re wrong and I think the incoming Health Secretary and the Prime Minister now have serious questions to answer about the CCTV, about the access, the passes, the contracts, etc.

Wild swimming scientist Heather Massey: ‘Hypothermia is not a pretty sight’

The physiologist and survival expert on the joys and dangers of cold water immersion

Dr Heather Massey is a researcher at the University of Portsmouth’s Extreme Environments research group and a seasoned open water swimmer. Having swum the Channel and competed in the world ice swimming championships, her research into the effects of extreme temperatures on the body is personal.

During lockdown the number of people enjoying wild swimming soared, but so did the number of deaths. Massey’s research examines whether cold water swimming is more likely to kill or cure.

The Oxford vaccine: the trials and tribulations of a world-saving jab

Posted on by

Amid bemusement from scientists at the deluge of often undeserved criticism, the Guardian pieces together the story behind the vaccine’s successes and failures

In January 2020, when most of the world slept soundly in ignorance of the pandemic coming its way, a group of scientists at Oxford University got to work on a vaccine to save the planet. They wanted it to be highly effective, cheap, and easy to use in even the poorest countries.

Prof Sarah Gilbert, Prof Andrew Pollard and others pulled it off. With speed crucial, they designed it and launched into trials before bringing in a business partner. The giant Anglo-Swedish pharmaceutical company AstraZeneca would manufacture it, license it around the world – and not make a profit until the pandemic was over.

Astronomers estimate 29 habitable planets are positioned to see Earth transit and intercept human broadcasts

For centuries, Earthlings have gazed at the heavens and wondered about life among the stars. But as humans hunted for little green men, the extraterrestrials might have been watching us back.

In new research, astronomers have drawn up a shortlist of nearby star systems where any inquisitive inhabitants on orbiting planets would be well placed to spot life on Earth.

Cloud spraying and hurricane slaying: could geoengineering fix the climate crisis?

Around the world, dozens of ingenious projects are trying to ‘trick’ the ocean into absorbing more CO2. But critics warn of unforeseen consequences

Tom Green has a plan to tackle climate change. The British biologist and director of the charity Project Vesta wants to turn a trillion tonnes of CO2 into rock, and sink it to the bottom of the sea.

Green admits the idea is “audacious”. It would involve locking away atmospheric carbon by dropping pea-coloured sand into the ocean. The sand is made of ground olivine – an abundant volcanic rock, known to jewellers as peridot – and, if Green’s calculations are correct, depositing it offshore on 2% of the world’s coastlines would capture 100% of total global annual carbon emissions.

High stress may make ‘broken heart syndrome’ more likely, study finds

Posted on by

Condition also known as takotsubo cardiomyopathy is brought on by an acute emotional shock

Two molecules associated with high stress levels have been implicated in the development of broken heart syndrome, a condition that mainly affects post-menopausal women and is usually brought on by severe stress, such as the loss of a loved one.

The syndrome, formally known as takotsubo cardiomyopathy, is characterised by weakening of the heart’s main pumping chamber and was first identified in 1990 in Japan. It looks and sounds like a heart attack and is consequently often confused for one.
