Singapore has suspended the use of video-conferencing tool Zoom by teachers, its education ministry said on Friday, after “very serious incidents” occurred in the first week of a coronavirus lockdown that has seen schools move to home-based learning, Reuters reports.

One of the incidents involved obscene images appearing on screens and strange men making lewd comments during the streaming of a geography lesson with teenage girls, according to local media reports.

These are very serious incidents. MOE (Ministry of Education) is currently investigating both breaches and will lodge a police report if warranted. As a precautionary measure, our teachers will suspend their use of Zoom until these security issues are ironed out.

Elimination: what New Zealand’s coronavirus response can teach the world | Michael Baker and Nick Wilson

Posted on by

New Zealand’s drive against Covid-19 is showing promise and it is not too late for other countries to follow

Epidemiologists love to evoke the memory of John Snow, who famously advocated removing the handle from the Broad Street pump in London, an action that helped to end a severe outbreak of cholera. In the face of the Covid-19 pandemic we need to take the same kind of decisive action, yet western countries have appeared remarkably slow to do so, despite the advantages of immense scientific knowledge and modern tools of pandemic control.

New Zealand now appears to be the only “western” nation following an articulated elimination strategy with the goal of completely ending transmission of Covid-19 within its borders. The strategy appears to be working, with new case numbers falling. Most cases are now returning travellers, who are safely quarantined at the borders, and the few remaining case clusters in the community are being traced and further spread stamped out. But it is far too soon to claim victory, and the country is remaining under an intense lockdown to support the elimination effort.

Care homes across globe in spotlight over Covid-19 death rates

Residential homes have emerged as key breeding ground for infections from Madrid to New York

Care homes for older people across much of Europe and North America are struggling to cope with the global coronavirus pandemic, prompting allegations of inhumane treatment and calls for high-level inquiries.

Appalling stories have emerged from residential homes, which have emerged as a key location for infections. People aged 70 and older are at higher risk of getting very sick or dying from the coronavirus. And people 85 and over are even more vulnerable, global figures show.

Tolkien was right: giant trees have towering role in protecting forests

Study highlights importance of biodiversity as part of strategy to stop planet overheating

Scientists have shown to be true what JRR Tolkien only imagined in the Lord of the Rings: giant, slow-reproducing trees play an outsized role in the growth and health of old forests.

In the 1930s, the writer gave his towering trees the name Ents. Today, a paper in the journal Science says these “long-lived pioneers” contribute more than previously believed to carbon sequestration and biomass increase.

WHO warned of transmission risk in January, despite Trump claims

Notes to global health leaders on 10 and 11 January highlighted possible infection routes

The World Health Organization warned the US and other countries about the risk of human-to-human transmission of Covid-19 as early as 10 January, and urged precautions even though initial Chinese studies at that point had found no clear evidence of that route of infection.

Technical guidance notes seen by the Guardian and briefings by top WHO officials warned of potential human-to-human transmission and made clear that there was a threat of catching the disease through water droplets and contaminated surfaces, based on the experience of earlier coronavirus outbreaks, such as Sars and Mers.

Research on Massospondylus carinatus embryos sheds new light on animals’ development

The fossilised skulls of dinosaur embryos that died within their eggs about 200m years ago, have been digitally reconstructed by scientists, shedding new light on the animals’ development, and how close they were to hatching.

The rare clutch of seven eggs, some of which contain embryos, was discovered in South Africa in 1976, with the developing young found to be a species of dinosaur called Massospondylus carinatus.

Southern hemisphere neighbours have developed different strategies but both are working – for now

Its more than 35,000km (21,750 miles) of coastline was always going to be Australia’s strongest advantage in keeping coronavirus at bay, but even so, the speed with which it was used was breathtaking.

Without warning on Thursday 19 March, the Australian prime minister, Scott Morrison, announced: “Australia is closing its borders to all-non citizens”. The ban was effective from 9pm the next day.

Experts reexamine eggs – some dating back to bronze age – to understand origins and designs

They are about the same size as a standard Easter egg, but are rather older – with some specimens dating back five millennia to the early bronze age.

A collection of decorated ostrich eggs belonging to the British Museum in London has been reexamined by experts in an effort to understand where they originated, and how their often elaborately painted or engraved designs were created.

New study finds ocean ecosystems likely to collapse in 2020s and land species in 2040s unless global warming stemmed

Wildlife species will die out and natural ecosystems collapse in the near future if the climate crisis goes unchecked, scientists have warned, as new research shows that the natural world is at far greater risk from climate breakdown than previously thought.

Catastrophe could strike this decade for some species, as key temperature thresholds are crossed. Instead of the anticipated gradual decline of species, there are likely to be a series of sudden collapses.

Scientists create mutant enzyme that recycles plastic bottles in hours

Bacterial enzyme originally found in compost can be used to make high-quality new bottles

A mutant bacterial enzyme that breaks down plastic bottles for recycling in hours has been created by scientists.

The enzyme, originally discovered in a compost heap of leaves, reduced the bottles to chemical building blocks that were then used to make high-quality new bottles. Existing recycling technologies usually produce plastic only good enough for clothing and carpets.

Humans living in Amazon 10,000 years ago cultivated plants, study finds

Findings from Bolivia show plants were domesticated in region shortly after last ice age

The Amazon basin was a hotspot for the early cultivation of plants, with inhabitants having munched on squash and cassava more than 10,000 years ago, researchers have revealed.

The team say the new findings from Bolivia offer direct evidence such plants were grown in south-west Amazonia, meaning the region has a claim to join the Middle East, China, south-west Mexico and north-west South America as locations where wild plants were domesticated shortly after the last ice age. The team say the discovery chimes with other clues.

Executive order says US will oppose any international effort to bar it from removing chunks of moon, Mars or elsewhere in space

The world may be racked by the coronavirus, but Donald Trump has less earthly concerns on his mind, too, after signing an executive order encouraging the US to mine the moon for minerals.

The executive order makes clear that the US doesn’t view space as a “global commons”, opening the way for the mining of the moon without any sort of international treaty.

Human impact on wildlife to blame for spread of viruses, says study

Increased contact with animals likely cause of outbreaks such as Covid-19, say experts, as conservationists call for global ban on wildlife markets

Hunting, farming and the global move of people to cities has led to massive declines in biodiversity and increased the risk of dangerous viruses like Covid-19 spilling over from animals to humans, a major study has concluded.

In a paper that suggests the underlying cause of the present pandemic is likely to be increased human contact with wildlife, scientists from Australia and the US traced which animals were most likely to share pathogens with humans.

Analysis depends on data – so predictions for Italy and Spain, where peak has passed, are more reliable than for UK

The Institute of Health Metrics and Evaluation in Seattle, based at the University of Washington, is the best organisation in the world at collecting data on diseases and mapping out why we fall ill.

Its Global Burden of Disease study is a massive collaborative effort that is valued and used in every country. But even for such an organisation, predicting what will happen to us all as a result of Covid-19 is a tricky business.
