Tasmanian devils slash population of brushtail possums that ‘overwhelmed’ tiny island

Posted on by

Possums on Maria Island expanded beyond usual habitat and had become ‘pretty significant predator’

The introduction of Tasmanian devils to Maria Island halved the population of brushtail possums, according to new research that suggests restoring top predators to ecosystems could help limit the number of overabundant prey.

In 2012, the carnivorous marsupials were introduced to the island off the east coast of Tasmania to create a geographically isolated insurance population free from devil facial tumour disease.

Existing UK fertility law should be updated to regulate modern treatments, says HFEA

Children born via sperm or egg donation would not need to wait until adulthood to find out more about their biological parents, under proposed changes to the law in the UK.

At present, donor-conceived children cannot obtain information about their biological parents until they are 18. But the Human Fertilisation and Embryology Authority (HFEA) said the law should be updated so this information can be made available after the birth of a child, should the donor choose.

Updated finding a departure from previous studies on how the virus emerged and comes with ‘low confidence’

The virus which drove the Covid-19 pandemic most likely emerged from a laboratory leak but not as part of a weapons program, according to an updated and classified 2021 US energy department study provided to the White House and senior American lawmakers, the Wall Street Journal reported on Sunday.

The department’s finding – a departure from previous studies on how the virus emerged – came in an update to a document from the office of National Intelligence director Avril Haines. It follows an FBI finding, issued with “moderate confidence”, that the virus spread after leaking out of a Chinese laboratory.

Ocean voyage to study declining sea ice levels cancelled after RSV Nuyina required repairs leaving climate scientists dismayed

A major scientific expedition to urgently assess record-low sea ice levels in Antarctica has been cancelled due to ongoing repairs on Australia’s icebreaking vessel, RSV Nuyina, with climate scientists expressing disappointment at “Band-Aid” solutions.

US scientists have this week reported that the floating ice around the continent – which protects melting glaciers from currents and warmer waters – has reached the lowest level ever recorded, in part due to unprecedented heatwaves in recent years.

Biden administration’s rule for federal scientists is a ‘gag order’, critics say

Posted on by

Federal scientists would largely be barred from publicly discussing research, which could have a ‘chilling effect’, experts say

The Biden administration has proposed what some critics label a “gag order” on federal scientists in the US that would largely bar them from publicly discussing their research, and could effectively prohibit them from taking part in controversial studies on issues like the climate crisis, chemical pollution and biosafety.

The rule would have a “chilling effect” on the nation’s scientific discourse, and a similar policy has already been used to censor scientists, said Jeff Ruch, Pacific director of Public Employees for Environmental Responsibility (Peer), a non-profit that protects federal researchers.

‘Crazy interesting’ findings by Australian researchers may reveal key to Covid immunity

Posted on by

University of Sydney scientists have found a receptor protein which ‘acts a bit like molecular velcro, in that it sticks to the spike of the virus’

Australian researchers have found a protein in the lungs that sticks to the Covid-19 virus like velcro and immobilises it, which may explain why some people never become sick with the virus while others suffer serious illness.

The research was led by Greg Neely, a professor of functional genomics with the University of Sydney’s Charles Perkins Centre in collaboration with Dr Lipin Loo, a postdoctoral researcher and Matthew Waller, a PhD student. Their findings were published in the journal PLOS Biology on Friday.

Scientist who edited babies’ genes says he acted ‘too quickly’

Exclusive: He Jiankui stops short of apologising for procedure that shocked the world of science in 2018

The scientist at the heart of the scandal involving the world’s first gene-edited babies has said he moved “too quickly” by pressing ahead with the procedure.

He Jiankui sent shock waves across the world of science when he announced in 2018 that he had edited the genes of twin girls, Lulu and Nana, before birth. He was subsequently sacked by his university in Shenzhen, received a three-year prison sentence, and was broadly condemned for having gone ahead with the risky, ethically contentious and medically unjustified procedure with inadequate consent from the families involved.
