A new type of white paint has the potential to cool buildings and reduce the reliance on air conditioning, say researchers.
In a study, the new product was able to reflect 95.5% of sunlight and reduce temperatures by 1.7C compared to the ambient air conditions.
The engineers involved say the impact is achieved by adding different-sized particles of calcium carbonate.
Buildings of all types are one of the biggest sources of CO2…

Black holes are powerful engines of pure gravity
, capable of pulling on objects so intensely that they can’t possibly escape. 
When those objects near the event horizon, they’re accelerated to incredible velocities. Now, some physicists are suggesting harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick, the new study finds, is to carefully set everything up so that particles
don’t get lost forever in the insatiable black hole. This new insight…

SpaceX CEO Elon Musk has confirmed that Starship and Raptor’s first triple-engine static fire was a success, opening the door for nosecone installation.
Around 3:13 am CDT, October 20th, Starship serial number 8 (SN8) successfully fired up three Raptor engines less than two hours after completing the first successful three-engine preburner test. With zero direct human intervention, SpaceX remotely detanked the rocket’s cryogenic liquid methane and oxygen propellant – the remnants now too warm to…
