Rewilding our cities: beauty, biodiversity and the biophilic cities movement

Buildings covered in plants do more than just make the cityscape attractive – they contribute to human wellbeing, biodiversity, and action on climate change

Our cities are dominated by glass-faced edifices that overheat like greenhouses then guzzle energy to cool down. Instead, we could have buildings that are intimately connected to the living systems that have evolved with us, that celebrate the human-nature connection that is central to our wellbeing.

As more of us in Australia live in urban areas and our cities grow, bringing nature into our cities is a key part of establishing and rebuilding that connection. As well as bringing beauty into urban environments, we know that people are healthier when they are connected to nature. Research also shows that crime rates decrease in areas with street trees and that property values increase.

Covid certificates on the cards for use in England since December

Report shows government was considering plan months before ministers went public

A government-commissioned report in December examined how Covid certificates could be used to decide whether people should be allowed into sports events, pubs and other crowded spaces, months before ministers publicly confirmed the plan.

A document prepared for NHS test and trace and seen by the Guardian shows that the research also looked into whether certificates could be made a condition of entry for family events such as weddings or even small casual gatherings.

Plea to ease Covid maternity rules as women continue to get bad news alone

But Not Maternity Alliance says postcode lottery remains despite guidance issued in December

The majority of women who have received bad news about their pregnancy since December were on their own at the time, despite the NHS ordering trusts to allow partners to be present throughout scans, labour and birth, the Guardian can reveal.

An alliance of pregnancy rights campaigners have written to the health secretary, Matt Hancock, urging him to draw up a roadmap for easing visiting restrictions in maternity services.

The ‘elite controllers’ who can naturally suppress HIV

Research into how some HIV-positive people keep the virus at bay promises to yield new treatment possibilities, from vaccines to gene therapies

The year was 1998 when Joel Blankson encountered a patient he would never forget. Blankson was working in the HIV clinic at John Hopkins School of Medicine, Baltimore, when an HIV-positive woman in her mid-40s arrived for some routine tests.

Blankson gave her a PCR test, intending to prescribe a newly developed combination of medicines called antiretroviral therapies to suppress the infection, and prevent her developing Aids.

Australian Covid vaccine rollout to continue after blood clot case in Melbourne

The acting chief medical officer says it is ‘likely’ the 44-year-old Victorian man’s condition is related to the vaccine

Australia’s acting chief medical officer says there will be no changes to the national vaccination program for Covid-19 while health authorities continue to investigate whether blood clots developed by a 44-year-old Victorian man are linked to the AstraZeneca jab.

Prof Michael Kidd said the Australian Technical Advisory Group on Immunisation (Atagi) and the Therapeutic Goods Administration (TGA) had not recommended any change to the rollout of the vaccine following an urgent meeting of health authorities on Saturday.

Seven UK recipients of Oxford jab reported dead after clotting

Experts say numbers of rare blood clots remain low and benefits of Covid vaccine far outweigh risks

Further cases of a rare blood clotting syndrome including seven deaths have been reported among recipients of the Oxford/AstraZeneca jab in the UK, although experts say the numbers remain low and the benefits of the vaccine far outweigh any risks.

The Medicines and Healthcare products Regulatory Agency (MHRA), runs a “yellow card” scheme to pick up suspected side-effects or other concerns for medicines and medical devices.

‘We’re in a really good place’: is Israel nearing the Covid endgame?

Vaccination centres are winding down and infections continue to fall as country reopens

At the peak of Israel’s Covid vaccination drive, the halls of a huge basketball arena in Jerusalem were filled with people, each anxiously waiting up to two hours until their number was called. More than 3,000 people a day were being vaccinated here in January.

On Monday, no more than 15 people lingered around long rows of empty chairs. Some barely had time to sit down before they were called to receive a jab. “They wait about 10 seconds,” said Shani Luvaton, the head nurse at the vaccination centre. She only uses half her booths for just a few hundred people a day.

‘We want to deliver’: Covid vaccine delays hit vulnerable Melbourne tower residents

Community health groups have nurses, GPs and locals ‘ready to go’, but a lack of deliveries has forced them to cancel vaccination clinics

For the past four months, in the towering Richmond housing estate of Melbourne, community health workers have been hard at work, preparing locals for the arrival of the Covid-19 vaccine.

It’s a difficult but vital task. Many of the roughly 2,000 residents are vulnerable or elderly, use shared services and are densely packed into the estate’s five towers, creating a high-risk Covid-19 environment.

Covid vaccine scheme ‘unacceptably slow’ in Europe, says WHO

Hans Kluge urges ramping up of manufacturing and asks governments to share excess shots

Europe’s vaccination campaign is “unacceptably slow” while rising infection rates in most countries across the region mean its virus situation is “more worrying than we have seen in several months”, the World Health Organization has said.

The WHO regional director for Europe, Hans Kluge, said on Thursday that vaccines “present our best way out of this pandemic. Not only do they work, they are highly effective in preventing infection. However, their rollout is unacceptably slow.”

Death without answers: an agonising 24-hour hunt for medical help in Guinea-Bissau

Bernardo Catchura spent a last desperate night seeking treatment in the healthcare system he had spent decades campaigning to improve. His wife is still unsure how he died

In their 15 years together, Maimuna Catchura had not known her husband to be ill. But one night in late January, 39-year-old lawyer, activist and musician Bernardo Catchura could not sleep, and complained of severe stomach pain.

The pain forced Catchura from his bed at his house in Bissau, Guinea-Bissau’s capital. That night he would navigate the country’s medical care maze, visiting pharmacies, clinics and hospitals. Before the night was through, he even considered crossing the border into Senegal to get help.

Damage: the silent forms of violence against women

How is it that those with the power to inflict most harm are blind to the consequences of their actions?

It is a truism to say that everyone knows violence when they see it, but if one thing has become clear in the past decade, it is that the most prevalent, insidious forms of violence are those that cannot be seen. Consider, for example, a photograph from January 2017. A group of identical-looking white men in dark suits looked on as their president signed an executive order banning US state funding to groups anywhere in the world offering abortion or abortion counselling.

The passing of the “global gag rule” effectively launched the Trump presidency. (It was scrapped by Joe Biden soon after his inauguaration a few weeks ago.) The ruling meant an increase in deaths by illegal abortion for thousands of women throughout the developing world. Its effects have been as cruel as they are precise. No non-governmental organisation (NGO) in receipt of US funds could henceforth accept non-US support, or lobby governments across the world, on behalf of the right to abortion. A run of abortion bans followed in conservative Republican-held US states. In November 2019, Ohio introduced to the state legislature a bill which included the requirement that in cases of ectopic pregnancy, doctors must reimplant the embryo into the woman’s uterus or face a charge of “abortion murder”. (Ectopic pregnancy can be fatal to the mother and no such procedure exists in medical science.)

New Covid vaccines needed globally within a year, say scientists

Survey of experts in relevant fields concludes that new variants could arise in countries with low vaccine coverage

The planet could have a year or less before first-generation Covid-19 vaccines are ineffective and modified formulations are needed, according to a survey of epidemiologists, virologists and infectious disease specialists.

Scientists have long stressed that a global vaccination effort is needed to satisfactorily neutralise the threat of Covid-19. This is due to the threat of variations of the virus – some more transmissible, deadly and less susceptible to vaccines – that are emerging and percolating.

Looking up health symptoms online less harmful than thought, study says

Results show increase in self-diagnosis accuracy after participants searched for advice online

That throbbing headache just won’t go away and your mind is racing about what may be wrong. But Googling your symptoms may not be as ill-advised as previously thought.

Although some doctors often advise against turning to the internet before making the trudge up to the clinic, a new study suggests that using online resources to research symptoms may not be harmful after all – and could even lead to modest improvements in diagnosis.
