Climate crisis: Scientists spot warning signs of Gulf Stream collapse

Posted on by

A shutdown would have devastating global impacts and must not be allowed to happen, researchers say

Climate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points.

The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown.

Zakynthos island and Chania on Crete hit by measures aimed at cutting Covid spread; advisers to government in Tokyo say surge requires harsher measures

With 16 million Australians again plunged into lockdown as authorities struggle to contain Delta variant outbreaks, the national cabinet is set to examine how allowing vaccinated residents to be freed from restrictions could provide a “powerful incentive” to be immunised.

The prime minister, Scott Morrison, will meet with state and territory leaders on Friday amid fresh tensions between New South Wales and the commonwealth over the state’s prolonged and expanding lockdown and as Victoria enters its sixth lockdown following fresh Covid cases.

I have been vocal publicly about our need and want for more vaccines.

We know the vaccines stop the spread. They protect life and keep people out of hospital. That’s why it is so critical and every jurisdiction around the world is finding Delta challenging.

Greece imposed a night-time curfew and banned music on two popular tourist islands on Thursday to contain the spread of Covid-19, its civil protection deputy minister said.

The Mediterranean country, which is trying to rebuild a tourist sector hard hit by the coronavirus pandemic, is also battling a wave of wildfires during a protracted heatwave, Reuters reports.

We call on the residents and visitors in these areas to fully comply with the measures to limit the spread of the virus.

The risks and rewards of vaccinating UK children against Covid

Analysis: official advisers have called for jabs to be given to children aged 16 and 17 in a rethink of policy

Just weeks ago, the Joint Committee on Vaccination and Immunisation (JCVI) recommended that children over the age of 12 should only be vaccinated if they were extremely vulnerable or lived with someone at risk, citing concerns about an inflammatory heart condition linked to the Pfizer/BioNTech jab. Now the JCVI has tweaked that decision to allow children aged 16 and 17 to be routinely offered the vaccine.

Coronavirus live news: England and Wales deaths reach three-month high; Indonesia struggles with surge in cases

Latest updates: Covid deaths registered in England and Wales in the week ending 23 July up 50%; Indonesia’s health workers struggle under weight of new cases

More than 200 areas across England and Wales had at least twice as many deaths than average during the first Covid, according to analysis by the Office for National Statistics (ONS).

The figures come as the number of coronavirus deaths registered in England and Wales in the week ending 23 July has reached 327, the highest figure recorded for three months.

Ivermectin may combat Covid infection and reduce infectiousness, a new Israeli study suggests.

The Jerusalem Post reports that the widely used anti-parasite drug was tested in a small randomised control trial, which is yet to be peer-reviewed, and saw 22% more patients who received ivermectin test negative for the virus by day six than the placebo group.

Hundreds of critical health workers in the Australian state of Queensland have gone into isolation as the country battles a growing Delta outbreak, while New South Wales raced to administer 6m vaccine doses before the scheduled end of lockdown in less than four week’s time.

Queensland’s chief health officer, Dr Jeannette Young, said health workers in quarantine included all the cardiac surgeons at the Queensland Children’s hospital, leading to delays in surgery and outpatient work.

Covid restrictions and screens linked to myopia in children, study shows

Hong Kong research suggests less time outdoors and more doing ‘near work’ accelerates short-sightedness

Spending more time indoors and on screens because of Covid restrictions may be linked to an increased rate of short-sightedness in children, researchers say.

The study, which looked at two groups of children aged six to eight in Hong Kong, is the latest to suggest that lockdowns and other restrictions may have taken a toll on eyesight: data from more than 120,000 children of a similar age in China, published earlier this year, suggested a threefold increase in the prevalence of shortsightedness, or myopia, in 2020.

Study says pigments on cave stalagmites were applied through ‘splattering and blowing’ more than 60,000 years ago

Neanderthals, long perceived to have been unsophisticated and brutish, really did paint stalagmites in a Spanish cave more than 60,000 years ago, according to a study published on Monday.

The issue had roiled the world of paleoarchaeology ever since the publication of a 2018 paper attributing red ocher pigment found on the stalagmitic dome of Cueva de Ardales to our extinct “cousin” species.

Research into non-injectable Covid vaccines brings hope for needle-phobics

Posted on by

Scientists say anxiety around needles could be playing role in vaccine hesitancy in the UK

The sight of a needle piercing skin is enough to chill a quarter of adult Britons and trigger up to 4% into fainting. But hope is on the horizon for needle-phobics as researchers are working on a range of non-injectable Covid vaccine formulations, including nasal sprays and tablets.

Almost every vaccine in use today comes with a needle, and the approved Covid-19 vaccines are no exception. Once jabbed, the body’s immune system usually mounts a response, but scientists in the UK and beyond are hoping to harness the immune arsenal of the mucous membranes that line the nose, mouth, lungs and digestive tract, regions typically colonised by respiratory viruses including Covid-19, in part to allay the fears of needle-phobics.

New Zealand prime minister Jacinda Ardern has taken a Covid-19 test after picking up a “seasonal sniffle” from her three-year-old daughter, the government spokesman said on Tuesday.

Ardern will step back from her duties for the day due to the sickness and the deputy prime minister Grant Robertson will take on the responsibilities, the spokesman said.

Doggerland: Lost ‘Atlantis’ of the North Sea gives up its ancient secrets

Posted on by

The land mass that linked Britain to continental Europe was rich in early human life until it flooded

The idea of a “lost Atlantis” under the North Sea connecting Britain by land to continental Europe had been imagined by HG Wells in the late 19th century, with evidence of human inhabitation of the forgotten world following in 1931 when the trawler Colinda dredged up a lump of peat containing a spear point.

But it is only now, after a decade of pioneering research and the extraordinary finds of an army of amateur archaeologists scouring the Dutch coastline for artefacts and fossils, that a major exhibition is able to offer a window into Doggerland, a vast expanse of territory submerged following a tsunami 8,000 years ago, cutting the British Isles off from modern Belgium, the Netherlands and southern Scandinavia.

A fall in case numbers last month raised hopes that Britain may be reaching herd immunity, but experts warn against complacency, given uncertainty about new variants and autumn’s return to school

John Edmunds has been at the centre of the unravelling of the Covid-19 pandemic since cases first appeared in January 2020. A member of Sage, the government’s scientific advisory group, and a professor of epidemiology at the London School of Hygiene & Tropical Medicine, he has consistently warned ministers about the threats posed by the disease.

These risks have often been clear in their nature. But today, 18 months after Covid-19 first appeared, he believes the nation stands at a point of maximum uncertainty about the future of the pandemic.
