Commentary: The greatest risk from AI comes from cells, not steel, with 70% of national security practitioners believing AI increases bioweapon risk and AI-aided researchers potentially making pathogens more deadly.

AI’s greatest threat is biological, not robotic
To mitigate the risks, safeguards such as mandating DNA screening and implementing regulations on AI development are needed.

Thanks to Canadian @shiventaneja.bsky.social for developing these instructions. The CR Box has a high clean air delivery rate for particles in the size ranges of wildfire smoke & should remove a large amount of heavier organic gas-phase components. All at a fraction of cost of other air cleaners.

It's #NationalIceCreamDay! Discover how science shapes the smooth, creamy texture of ice cream in this infographic: www.compoundchem.com/2015/07/14/i... #ChemSky 🧪
Infographic on the chemistry of ice cream. Ice cream is formed from fats, proteins and emulsifiers, which in combination stabilise air bubbles in ice cream. Small crystals are needed for smooth ice cream, and air makes up 30-50% of ice cream's volume. A range of flavouring compounds are used. Stabilisers, often extracted from seaweed, are added in small amounts to reduce the rate of melting.

What's Earth made of? The latest edition of #PeriodicGraphics in @cenmag.bsky.social journeys to the centre of Earth to look at the elements and minerals that make up our planet's different layers: cen.acs.org/physical-che... #ChemSky 🧪
Infographic on the composition of Earth. Scientists determine the composition of Earth by analysing surface rocks and inferring the density and composition of deeper layers from how seismic waves move through Earth. 

Oxygen is the most abundant element in the crust. Mafic rocks, rich in magnesium and iron, dominate oceanic crust. Felsic rocks, higher in silicates, are the most abundant in continental crust.

The mantle is composed mainly of magnesium-rich silicate minerals, such as olivine and pyroxene. The lower mantle contains less magnesium than the upper mantle.

Earth's outer core is liquid, while the inner core is solid. Both layers consist mainly of an iron-nickel alloy with lighter element impurities. The core’s exact composition is still unknown. Molten iron stirring in the outer core drives Earth's magnetic field.

From @brianbilston.bsky.social, send me a slow news day... 🙏
Serenity Prayer
Send me a slow news day
A quiet, subdued day,
In which nothing much happens of note,
Save for the passing of time,
The consumption of wine,
And a re-run of Murder, She Wrote.

Grant me a no-news day,
A spare-me-your-views day,
In which nothing much happens at all,
Except a few hours together,
Some regional weather 
A day we can barely remember.

Indirect costs = the costs of keeping a university running. Heating and lighting it, the library, the IT department, HR, cleaning etc. The actual costs are perhaps 50-100% of the direct costs of research. This is a pillow on the face of academic research in USA.

The NIH capping the indirect cost rate (IDC) for grants at 15% can best be described as a direct assault on Universities. It’s such a bureaucratic, innocuous sounding thing that actually means that research universities will be kneecapped. Thousands of employees across the US will lose their jobs.
