Vera C. Rubin Observatory first images
A spectacular new 10-year telescopic survey of the universe gets underway in Chile. Also, a project to create human chromosomes completely synthetically.Almost three decades ago Tony Tyson (now of UC Davis) and colleagues were standing in the control room of the world’s biggest (at the time) digital astronomical camera. It was 3am when he suggested astronomers could do better. This week, the Vera...

Half a universe once lost now found
The universe is thought to consist of 70% Dark Energy, 25% Dark Matter, and just 5% Baryonic matter which is the atoms that make up you and me. At least, that’s what the models suggest. But a well-kept secret between astronomers and cosmologists for all these years has been that they have not actually ever seen almost half of that 5% normal matter because it is thinly dispersed as gas between the...

The first solar polar pictures
ESA’s Solar Orbiter camera probe begins raising its orbit towards the sun’s poles, whilst Betelgeuse’s elusive buddy continues to sneak past our best telescopes.Earlier this year, Solar Orbiter started to stretch its orbit over greater latitudes – effectively standing on cosmic tiptoes to catch a glimpse of the Sun’s poles. This week, we have seen the first ever pictures of them, and as solar...

Potential fungal 'Agroterror'?
What is Fusarium graminearum and why were scientists allegedly smuggling it into the US? Also, Alpine Glacier collapse and an HIV capitulation.The FBI has accused two Chinese scientists of trying to smuggle a dangerous crop fungus into the US, calling it a potential agro-terrorist threat. But the fungus has long been widespread across US farms, and elsewhere, and is treatable. So what’s going on?...

Thirteen months to a chip off the moon
China is aiming to join the small club of nations who have successfully returned scientific samples of asteroids for analysis on earth, teaching us more about how our and potentially other solar systems formed. Tianwen-2 launched successfully this week, bound for an asteroid known as Kamo‘oalewa, which sits in a very strange orbit of both the earth and the sun, making it a “quasi-satellite”. Last...

WHO Pandemic Agreement reached
This week, 124 countries agreed at the World Health Assembly in Geneva on measures aimed at preventing a future pandemic. The agreement very strongly favours a “One Health” approach, appreciating how so many potential pathogens originate in human-animal interactions. Still to agree on the terms of how to share pathogens and information with global science and vaccine researchers, eventually the...

Vaccinating rabies’ reservoir dogs
In 2015, the World Health Organisation set the goal of eradicating rabies deaths from dog-bites to “Zero by 2030”. A team at the University of Glasgow and colleagues in Tanzania have been assessing the efficacy of dog vaccination schemes for reducing the numbers of human infections over the last 20 years. As Prof Katie Hampson tells Science in Action, in rural areas especially, vaccinating dog...

Gain-of-Function: Loss-of-Funding
This week, the White House posted an executive order which details the administration’s intent to stop ‘dangerous gain-of-function research’. We talk to Gigi Gronvall, an immunologist and biosecurity expert at Johns Hopkins University who fears the timing and added bureaucracy could stop all sorts of important biosciences unnecessarily, and that the order is somewhat ideologically driven.Also,...

Scientists of the world unite
Scientists from around the world have gathered together at the annual European Geosciences Union general assembly, to discuss current projects, working hypotheses and potential findings. There are nearly 18,000 in attendance this year and there is much to learn. AMOC – the Atlantic Meridional Overturning Circulation - brings warmth to the north and cooler waters to the south in huge volumes....

Wet market SARS CoV-2 origins revisited
Last week, the website covid.gov looked very different, containing information on coping with covid and US research. This week it leads you to a White House webpage outlining the lab-leak hypothesis – that the pandemic was the result of dodgy lab work at the Wuhan Institute of Virology. The scientific consensus however continues to suggest a zoonotic crossover event. And a preprint recently...
