Science stories of the week

Not a headline I wanted to read.

Bird flu in cats points to risk of another pandemic​

Paywall so...

https://phys.org/news/2025-05-bird-flu-cats-pandemic.html - this is swine flue H5N1

Just a little back ground on this to tie it all together

Spanish flu (that did not originate in Spain) was also H1N1 - this killed about 50 million people.

This mutated over time as do all living things and we now have "seasonal" flu, also H1N1 - this is an Influenza type A

The H and N are types of protein found on the virus.

 
Not 'this week,' but close enough...thought it was interesting.


An oasis compared to the kind of "Free thoughts" and "Pseudoscience" topics that apparently dominate this week.

  • The plug flow from four 32-centimeter-long tubes for 20 seconds produced enough electricity to continuously power 12 LED lightbulbs during that time. “We think it will be helpful in rainy places, including tropical countries like Singapore,” Soh says.

In contrast to places where springtime is about it for rain.

This is weird.

Length contraction is a feature of SR but the rotation is new to me, I had not thought it through fully.

Some background here and if you scroll down the Penrose- Terrel effect is mentioned "Visual effects."

  • "Technically, it is currently impossible to accelerate rockets to a speed at which this effect could be seen in a photograph. However, the group led by Peter Schattschneider from USTEM at TU Wien found another solution inspired by art: they used extremely short laser pulses and a high-speed camera to recreate the effect in the laboratory. "We moved a cube and a sphere around the lab and used the high-speed camera to record the laser flashes reflected from different points on these objects at different times," explain Victoria Helm and Dominik Hornof..."
So basically a simulation of the appearance or visual illusion that one might observe at that speed, of a couple of uncharacteristically plain or "devoid of surface details" Borg vessels. (The spherical version of the latter being rarely witnessed in the ST franchise.) Hopefully more imitations to come of effects that would be encountered under extreme conditions.

Transmission of transgenic mosquito-killing fungi during copulation


From the article above.

"A team of researchers including a University of Maryland entomologist has successfully turned the pesky mosquito's sex life into its downfall.

By creating what amounts to a sexually transmitted disease specifically for mosquitoes, the scientists unveiled a potentially powerful new weapon in the global fight against malaria."

The paper.

800,000 Galaxies at your fingertips.

More from Webb, once you start playing around with the link below, it becomes a little addictive.
You can zoom in and view the individual pixel, my understanding is that spectral data is available for each one, that was one of the features of the instruments.
Zooming right in then out step by step illustrates the incredible technology Webb has in its locker.
You have other features too, top right you can change filters if you know what you are doing!
