What happens when you try to chop a photon in half?
A photon is a single particle of light, and under normal circumstances, it can’t be divided. But a photon is also not a particle, in the sense that it does not have a specific location. Instead, it is an extended object. So if a photon is only partway through the process of reflecting from a

The Space Force is now seeking to buy up to $30 billion in rocket launches
The Space Force originally estimated the Lane 1 launch providers would compete for at least 30 task orders over a five-year period. Officials put a ceiling of $5.6 billion on the Lane 1 contract to cover these 30 missions. The Space Force capped the Lane 2 contract at $13.7 billion last year, a number officials

As mosquito ranges expand, better monitoring is key to preventing disease
Monitoring programs are typically labor-intensive and expensive, requiring teams to set and check traps, alongside specialists who can identify, sort, and test the samples. While some traps attract female mosquitoes with “stinky water” loaded with decaying organic material, others require dry ice to release carbon dioxide that mosquitoes sniff out when hunting for mammals. But

The report oil companies are worried about: Climate attribution science
These approaches are still the subject of ongoing development, so the report has two recommendations: researchers should be very transparent about the uncertainties in what they’re doing, and they should develop tools to make these analyses useful for disaster preparedness. Knowing that a new weather extreme is possible is far less useful than knowing what

These painted e-tattoos could be the future of wearable biosensors
Scientists at Pennsylvania State University have developed a novel conductive ink that can be painted directly onto the skin in colorful custom designs, turning into a functional electrode for biomonitoring after drying. They described their work in a new paper published in the Proceedings of the National Academy of Sciences (PNAS). As previously reported, epidermal

SpaceX is gearing up for Starship’s 13th test flight later this week
One reason SpaceX isn’t attempting an orbital flight this week is Starship’s failure to complete one of its test objectives on the last launch, when the spacecraft was supposed to ignite one of its six Raptor engines for a brief burn in space. The spacecraft skipped the burn after a Raptor engine shut down prematurely
