‘Magnetic turd’: scientists invent moving slime that could be used in human digestive systems

Researcher who co-created substance says it is not an April fool’s joke and they hope to deploy it like a robot

Scientists have created a moving magnetic slime capable of encircling smaller objects, self-healing and “very large deformation” to squeeze and travel through narrow spaces.

The slime, which is controlled by magnets, is also a good electrical conductor and can be used to interconnect electrodes, its creators say.

Seabed regulator accused of deciding deep sea’s future ‘behind closed doors’

The ISA, obliged to frame industry rules by 2023, drops reporting service and is accused of lacking transparency in plans for mining
• Podcast: The race to mine the deep sea

The UN-affiliated organisation that oversees deep-sea mining, a controversial new industry, has been accused of failings of transparency after an independent body responsible for reporting on negotiations was kicked out.

The International Seabed Authority (ISA) is meeting this week at its council headquarters in Kingston, Jamaica, to develop regulations for the fledgling industry. But it emerged this week that Earth Negotiations Bulletin (ENB), a division of the International Institute for Sustainable Development (IISD), which has covered previous ISA negotiations, had not had its contract renewed.

Covid lockdown extended in Shanghai as outbreaks put economy on the skids

China’s largest city and financial powerhouse is struggling to cope with the country’s worst outbreak since the start of the pandemic in Wuhan

Shanghai has been plunged into an extended lockdown and some residents face another 10 days of isolation in their homes as China’s strict zero-Covid policy threatens to derail the country’s economy.

The eastern half of China’s biggest city had been due to emerge on Friday from a four-day lockdown aimed at crushing a persistent outbreak of the Omicron variant, but the extension was announced late on Thursday night.

Hundreds fitted with artificial pancreas in NHS type 1 diabetes trial

Adults and children wear device that monitors glucose level and adjusts amount of insulin delivered

Hundreds of adults and children with type 1 diabetes in England have been fitted with an artificial pancreas that experts say could become the “holy grail” for managing the disease, in a world-first trial on the NHS.

The groundbreaking device uses an algorithm to determine the amount of insulin that should be administered and reads blood sugar levels to keep them steady. The NHS trial has so far found the technology more effective at managing diabetes than current devices and that it requires far less input from patients.

Failure to consider long Covid impact will hit UK economy, says expert

Dr Nathalie MacDermott says condition has substantial impact on people’s ability to work and costs to government and business

The UK will pay an economic price for failing to consider long Covid when lifting restrictions and recommending vaccinations for children, a doctor has warned.

The decision to drop all Covid rules in England was largely based on whether the NHS could handle the number of sick patients, but far more people are expected to develop long-term medical problems after fighting off the virus.

Global melanoma rate to increase by 50% by 2040, researchers predict

Australia’s skin cancer rate rising in over 50s, but ‘declining quite steeply’ among younger age groups

New cases of melanoma are set to increase by 50% globally by 2040, with a 68% increase in deaths, according to new research.

An international team of researchers have analysed the global burden of melanoma, which accounts for approximately one in five skin cancers. Data from the International Agency for Research on Cancer estimated that there were 325,000 new melanoma cases and 57,000 deaths in 2020.

Experts push for genetic testing to personalise drug prescriptions

Pharmacogenomic testing could save the NHS money in the long term and reduce the risks of side-effects

Genetic testing to predict how individuals will respond to common medicines should be implemented without delay to reduce the risk of side-effects and ensure that everyone is given the right drug at the right dose, experts have said.

About 6.5% of UK hospital admissions are caused by adverse drug reactions, while most prescription medicines only work on 30% to 50% of people. A significant part of this is due to genetics: almost 99% of people carry at least one genetic variation that affects their response to certain drugs, including commonly prescribed painkillers, heart disease drugs and antidepressants. By the age of 70, about 90% of people are taking at least one of these medications.

‘Africa must be self-sufficient’: John Nkengasong on learning the deadly lessons of pandemics

The outgoing director of Africa Centres for Disease Control has seen Ebola, Aids and now Covid – and warns complacency is dangerous

The past five years have been “like going from one fire to the next, with barely any time to catch your breath”, says John Nkengasong, the outgoing head of the body charged with responding to health emergencies in Africa.

A relentless term as the first director of the Africa Centres for Disease Control and Prevention (Africa CDC) saw Nkengasong manage the response to Ebola and Lassa fever outbreaks. But nothing compared to the formidable test brought by Covid-19.

Australian scientists solve mystery of moment monotremes migrated

Fossil analysis is shedding new light on the origins of egg-laying mammals and their arrival on the continent

Researchers have pinpointed exactly how and when echidnas likely arrived in Australia as part of a fossil analysis shedding new light on the origins of egg-laying mammals.

The platypus and four species of echidna are the only remaining living monotremes – mammals that lay eggs instead of giving birth to live young. New analysis of every monotreme fossil discovered to date has recast the earliest history of the animals.

Shanghai rules out full lockdown despite sharp rise in Covid cases

Concern about economy leads city to try targeted approach with rolling restrictions of individual neighbourhoods

Shanghai has recorded a sharp rise in Covid-19 cases, but officials have ruled out a full lockdown over the damage it would do to the economy.

Millions of Chinese in affected areas have been subjected to city-wide lockdowns by an Omicron-led outbreak that has sent daily case counts creeping ever-higher, though they remain insignificant compared with other countries.

‘Climate smart’ policies could increase southern Africa’s crops by up to 500%

Researchers outline urgent steps to improve food security in the face of increasing natural disasters caused by the climate crisis

The climate crisis is threatening food stocks in sub-Saharan Africa, but a comprehensive approach to food, farming and resources could increase crop production by more than 500% in some countries in the region, according to new research by more than 200 experts.

There is no single technological fix to the threat posed by the barrage of natural disasters striking the region, they said, but significant improvements could be achieved with new approaches, based on modelling done by the network of researchers in Malawi, Tanzania, South Africa and Zambia.

Wolverine fish and blind eel among 212 new freshwater species

Report from Shoal on 2021’s newly described species shows ‘there are still hundreds and hundreds more freshwater fish scientists don’t know about yet’


Scientists are celebrating 212 “new” freshwater fish species, including a blind eel found in the grounds of a school for blind children and a fish named Wolverine that is armed with a hidden weapons system.

The New Species 2021 report, released by the conservation organisation Shoal, shows just how diverse and remarkable the world’s often undervalued freshwater species are, and suggests there is plenty more life still to be discovered in the world’s lakes, rivers and wetlands.

Mystery owner of Stan the T rex finally revealed following $31.8m auction

Paleontologists celebrate ‘happy ending’ as Abu Dhabi museum is revealed as owner, after fearing implications of sale to secret buyer

On 6 October 2020, a mysterious buyer paid a record-breaking $31.8m for the famous Tyrannosaurus rex skeleton known as Stan.

The rare, mostly complete skeleton of the dinosaur quickly vanished from the public eye. Paleontologists were left worried that the auction sale to a secret buyer would drive up the cost of rare skeletons, price out smaller museums and deny researchers – and the public – access to them.

Music improves wellbeing and quality of life, research suggests

A review of 26 studies finds benefits of music on mental health are similar to those of exercise and weight loss

“Music,” wrote the late neurologist Oliver Sacks, “has a unique power to express inner states or feelings. Music can pierce the heart directly; it needs no mediation.”

A new analysis has empirically confirmed something that rings true for many music lovers – that singing, playing or listening to music can improve wellbeing and quality of life.

European Space Agency suspends €1bn Mars mission with Russia

The ESA has commissioned a study of how to get ExoMars off the ground without Roscosmos involvement

The European Space Agency has suspended its €1bn (£844m) ExoMars mission, a joint project with Russia that was due to launch a robotic rover in September. Member states of the ESA voted on Thursday to cancel the launch because of the Russian invasion of Ukraine.

“The decision was made that this launch cannot happen, given the current circumstances and especially the sanctions that are imposed by our member states,” said agency director general Josef Aschbacher. “This makes it practically impossible, but also politically impossible to have a launch of [the rover] in September.”
